Latest / Uncomfortable Conversations with Josh Szeps / "Are We Scientifically Illiterate?" with Prof. Luke O'Neill
Transcript
- 0:00Gay humans do your research. They say do your own research
- 0:07Watch YouTube videos listen to podcasts question the mainstream narrative open your eyes
- 0:14Is that the path to wisdom or is it the path to madness?
- 0:20Cannot perhaps be both
- 0:23I've lately become something of an agutator against
- 0:27Taking too much personal responsibility for understanding every issue
- 0:31The world is just too complicated
- 0:33We need to outsource
- 0:35Most complex facts about the world to people who spend their whole lives studying them
- 0:40It is just not rigorous. It feels rigorous, but it's not rigorous to
- 0:47See an academic paper tweeted by someone with a PhD on Twitter and to let that out way the considered opinions of the mainstream
- 0:56Establishment which knows how to put that paper in context and what the counter-vailing evidence might be and how to weigh that
- 1:03Paper against others that contradict it and how to adjust for
- 1:06Statistical anomalies that I might not be well trained enough to consider
- 1:11We just can't do all of that by ourselves. We can't all be experts in everything
- 1:16But on the other hand, we also don't want to be sheeple
- 1:20We don't want to be
- 1:22gullible in believing everything we're told
- 1:25So what is the answer especially in a world where fewer and fewer people trust fewer and fewer sources of information about the
- 1:32Most basic challenges that we face like pandemics and climate chaos and democracy itself
- 1:39One place to start is by listening to all sides, but not giving them equal
- 1:45Credence
- 1:47By respecting the consensus, but not pillorying the dissidents
- 1:53by
- 1:54Refusing to talk down to the irrational and
- 1:57By calmly finding a common ground of reason and compassion with each other. So
- 2:03This is a podcast about not glossing over disagreement, but encouraging it in other words about having conversations that are
- 2:11sensitive and respectful and common ground seeking, but sometimes inevitably
- 2:17constructively
- 2:19uncomfortable
- 2:29Today on the show a delightful educator of science Luke O'Neill, professor
- 2:34Luke O'Neill, professor of biochemistry at Trinity College Dublin. He's a celebrated Irish popularizer of
- 2:43science
- 2:44He as well as being an immunologist himself and widely acclaimed scientist
- 2:50He also engages with the public a lot on scientific topics especially in Ireland and abroad
- 2:54He's got a weekly science slot on the Irish national radio station news talk
- 2:59He won a book of the year award in 2020 for a book called Nevermind the Bollocks. Here's the science
- 3:06Can you imagine imagine any any more Irish title than that and
- 3:11He wrote a memoir like a diary covering COVID-19
- 3:15Which was entitled keep calm and trust the science a remarkable year in the life of an immunologist
- 3:21I just wanted to get his thoughts about science literacy and how we can all get a little bit more rational
- 3:26Please enjoy professor Luke O'Neill
- 3:29I
- 3:38Don't know what you have to break this and I'll see if we've got some levels
- 3:42I'm having a large crop of coffee
- 3:45As far as it's 7 a.m. It's unreasonable for me to
- 3:49Ask you what you had for breakfast some fair isn't I'm not I'm not having the full Irish
- 3:53That's for that very good all right have you got me just you sound very clear of us say I'm in a studio mate
- 4:04You see now. What do you got? Yeah? Yeah, I'm in vacation
- 4:10It's been an interesting couple of years for science and the public understanding of science because I I feel like
- 4:17A few years ago it meant something to say, you know follow the science on something and you know
- 4:22You could be I expose the main fault line might be climate science and
- 4:27And now I feel like when I hear someone say, you know
- 4:31Well, you know, let's just follow the science. I don't know whether they mean let's trust the institutions that are telling us
- 4:38The science or yeah, I mean
- 4:41Institution can't be trusted and I've done my own research and his data that I've found that contradicts the mainstream
- 4:47Narrative what what is science and what does it mean to trust it?
- 4:50Well, you're right. Just incredible. What's happening away for obvious reasons scientists? I mean in Ireland
- 4:56Every single news item had a scientist kind of think disgusting code
- 5:00But obviously, you know, so it's been in the deepest faces I had to break it, but it wasn't just Ireland. It was
- 5:07Exactly, yeah, we all over the fact I've never seen so many immunologists becoming household names
- 5:12That's right. That way you all over the world your public health
- 5:15I'm proud to give West conferences every single day, you know, we'd all have
- 5:20Here in Sydney we would huddle around the television at a precisely 11 a.m
- 5:24Every day more than a year and the premier of the state would stand up and then she'd be followed by the you know the chief
- 5:29Health Officer and you know, we'd be gambling on what the number of cases would be and
- 5:35Yeah, yeah, I know I know this obsession that happens. Yeah, it's a strange business that the world and I've been doing science
- 5:42stuff for years in the media you see so so now now that it's all calmed down here anyway, we're back to normal
- 5:48Yeah, stories which know be listened to you
- 5:52Yeah, unless there's a penguin who just had sex in a zoo or something
- 5:56Yeah, that's not a big thing. Yeah, that feels good stuff. Yeah, I always go
- 6:01There was always a minority of well-meaning people listening to science and discussing it and buying the books and the bookshops and all that kind of thing
- 6:08You know, there was always a reason a little for a set of people you might say doing that, but one thing they got me just was a book of mine came
- 6:15I'd last year in Ireland. It's got never mind the Bollocks series of science
- 6:18You see it's a title and that outsells lots of other books and the publisher was amazed because you know
- 6:24It wouldn't normally see a science walk out selling say Obama's by out of biography or whatever
- 6:28So that's shift towards science has definitely been evident great and and my my job is to say what science is you see it's empirical
- 6:36Based on data. That's what science is really a hypothesis
- 6:39You do an experiment you get data and that that's no entrance the frame hopefully
- 6:44But you're quite right the vast majority of people are professional scientists
- 6:46So how they how they're engaging with this is still an ongoing process is the way I would put it
- 6:51I put it in the long run. It'll it'll matter, you know, but I mean these will take size more
- 6:55I mean it's easy when it's cut when it's a cut and dried thing
- 6:58But the problem is especially in an unfolding uncertain climate like a pandemic
- 7:02The you know, it's it's easier said than done to say you've got a hypothesis and then you get data and you test the hypothesis and
- 7:10You follow where that leads because the layperson is not necessarily well trained enough to understand all the mitigating counter effects that that
- 7:19particular data set might include and to understand it in the context of all the other peer reviewed studies that are going on especially
- 7:26When there is genuine uncertainty in the scientific community
- 7:28So I feel like some of the most quite unquite scientifically minded people in terms of the people who think that they're doing their own
- 7:35Science are actually the most misled because they'll see something on social media which will be from really from a you know
- 7:42Great a legit authority, but we don't know how to interpret it offset it very true. It's very true
- 7:49And you're stuck then trying to trust the so called experts and voices you might trust you see and then that that comes down to
- 7:55A question to trust more than empirical evidence exactly and that unless the way people have to be because I spent eight years
- 8:02Training to be a scientist remember so we can't expect my next or an Aver who isn't a scientist to have the same level of
- 8:08Of kind of a of in-depth knowledge that I would have and I mean we're right with all due respect
- 8:13We may not even expect you to have the same level of in-depth knowledge of another field of science
- 8:18And this is how you'll see people with PhDs coming forth and you know spouting some sort of vaccine misinformation nonsense
- 8:24Yeah, and their followers will say look. I mean, this is a highly credentialed individual and that makes it that makes it tricky
- 8:31Very tricky very and then it comes down to just a feel all most I think
- 8:35And it's very hard isn't it? I hear exactly what you're saying. I mean all I would ever do in the media is try to give the evidence
- 8:42That now you know and I've had if I sent any tweets out
- 8:45I always put a link to the paper and do my best to say here's the evidence
- 8:48But you quite like these are very technical things aren't they so so you need the so-called expert to be the mediator between the
- 8:54Complexity of the science and then and then a general audience and that that's a tricky especially with this you're right normally before
- 9:00The pandemic there'd be a discovery made it was pretty definitive and you can describe it with confidence that this
- 9:05This is what was found in this lab and this is what this story might mean with this one
- 9:09It was changing all the time because you knew in the famous words of the big levels can you shit?
- 9:14Keep keep coming to light so so that was the tricky bit here and then how do you convey that you know and that's right
- 9:20I think what's what's good is it's like my day job anyway if I go to a scientific conference I hear a speaker
- 9:25Oh my god, I don't trust that guy. You know how I don't like a lab or a day look that's that's the scientific process
- 9:30It's always about debate read you know and finally getting to some kind of bottom line and the good news is we did get the bottom lines with this
- 9:37With this virus. We know a lot about us. We know a lot of information. We know about various approaches to
- 9:42To study it and make the vaccines and therapies and all kinds of things, you know, so so things for me
- 9:47As you would imagine given the number zeta for science
- 9:50Science is delivered on this one huge for us as a planet. Well science may have but the scientific conversation may not have
- 9:58That's true. Well, that got very garbled and there were lots of you know as you say missed information and to it and very
- 10:03reputable
- 10:04People saying certain things that that I would have said I don't like the look of that
- 10:08You know, for instance, give my scientific training but about a lay audience wouldn't be able to say that maybe so it's a really
- 10:14A really difficult isn't it in a sense and this applies to many scientific topics not just COVID
- 10:18Well, yeah, but I mean this one in particular bumps up against our real lives in a way that many scientific topics don't
- 10:24You know when you so you come up with the vaccines and now we have to convince eight billion people or six billion people
- 10:30Have many people might be eligible for it to all have something injected into them and then yeah
- 10:36You know, that's a proactive thing that we have to do. So I've got four-year-old twins and I'm frankly
- 10:43somewhat relieved that
- 10:45They weren't five at precisely the point that they would have been eligible to get vaccinated just because
- 10:53they've had COVID and it was fine and
- 10:56You know, I'm not sure what the what the risk balance would have been between the threat of COVID to a five-year-old versus
- 11:03vaccine side effects for a five-year-old, you know, it's a no-brainer if you're over the age of 40 or something
- 11:09But I think people got got concerned about the state requiring everybody to do something in the absence of absolutely unclad
- 11:18information
- 11:19Yeah, I'm very understandable special parents and kids that's a hundred percent
- 11:23I understand there was an anxiety and if you don't trust your state you're in trouble, aren't you?
- 11:26You know, why would I believe my government if I don't trust my government to do certain things and that became an issue in
- 11:32NASA countries where the vaccine uptake was low even for adults
- 11:36Yeah, I don't I don't trust that guy on the telly telling me this stuff you can get lost kind of territory, you know
- 11:41again
- 11:43Well, I think is you got to appeal to people's sense of reason and then when being reasonable that's the world I often use
- 11:49You know and they can't look at all the data can they the endless Pfizer trial data with 500 pays document
- 11:56That's ridiculous isn't it you know so they end up having to trust the experts then see yes
- 12:00I like trusting their doctor if you're sick and you go to your doctor and suggest something for you
- 12:05You might actually trust the doctor and so I'll go for that, you know
- 12:07But again, it comes down to that word trust in a way. Yeah. How how's the trust doing in Ireland
- 12:13Yeah, we were very happy here overall. I think we got the 97% vaccination of our adults population
- 12:19well with the booster and everything which is great, you know
- 12:22Children, I'd say what it's the same as you guys in the sense them is a bit of a noxence here and there but many parents
- 12:27Still vaccinated they they they accept that this is just another vaccine that they're given their kids loads of vaccines
- 12:32Anyway, no, I know it's new that that was where the anxiety would come from but by and large Ireland did extremely well
- 12:37I think we're third in Europe for our vaccine of take care of great and Josh
- 12:41I see that as evidence of a functioning educated democracy
- 12:45You see such evidence that
- 12:47People are reasonable here in Ireland not everybody obviously it was fair enough
- 12:50But the majority did they they just took this on faith a lot of the time and went first, you know
- 12:55Interesting that you mentioned functioning educated democracy
- 12:57um
- 12:58What do we need to do to make sure that we are more functioning more educated and more democratic?
- 13:04Yeah education education education education right phrase isn't that you know
- 13:08You've got you've got to have a very high level of an education in any country always and I'm a educationist as well
- 13:14Obviously, you know in Ireland they do science up to the age of 16 and school here
- 13:17So it's quite older than some other countries, you know
- 13:20So all you can do is educate people in school
- 13:22How to look at the complexities we're discussing to be honest like like people have to decide now for themselves
- 13:27Based on what they're seeing in social media whether they go whether they believe something or not
- 13:31Don't they and education helps that the start of education really I think is is the starting point for all of this
- 13:37The purpose of education
- 13:39One definition Josh is to make people reasonable
- 13:42Didn't work a course in many countries. Why did you
- 13:45But that's the goal of education radius to make people reason. That's all you know for with an education system one level
- 13:51And
- 13:53And as I say in Ireland we seem to have achieved that was already very happy about really
- 13:57And yet the people who cite the most statistics and the most data are sometimes the most unreasonable because this
- 14:04Rabbit hole, you know, I mean kind of but you've said it recently
- 14:07But you know if you meet if you encounter someone who knows every single
- 14:12minute detail about what happened on the 22nd of November
- 14:151963 was it when JFK was shot
- 14:19Yeah, then you can bet that that person is a conspiracy theorist who is not
- 14:23Yeah, you know as connected or the moon landing or something if they know precisely what the material that the flag was made out of was or something
- 14:30Then they're likely to be actually less reasonable than someone who takes it on faith
- 14:36That's true. Yeah, well the question there is what gives rise to unreasonableness in a way
- 14:39You know, and it's a very complex human trait. You know, it can be it's based on human psychology that dreaded
- 14:45aspect of science, which is always very hard to pin down
- 14:48But some people who are highly educated can be extremely unreasonable
- 14:52So the two the two don't directly correlate necessarily again. You look at my statistics on average, you know what I mean
- 14:58Yeah, people are going to education on average. They should be more of these for the law is these elites
- 15:02The law is the mavericks we like mavericks and science by the way who who kicked the tires a lot
- 15:06That's not a bad thing in science by the way, you know
- 15:09But it always for me it comes down to just show me your evidence show me your data
- 15:12Which would happen to me at a professional scientific conference anyway, you know
- 15:16You can say what you like of course yet. Oh, it's a free free world
- 15:19Hopefully, but you got to back it up a data and then I might say oh, maybe that goes right
- 15:23And in my business and immunology the science has changed over decades because new again new shit comes to life
- 15:29If you're reasonable as a scientist you accept that, you know
- 15:32The change or opinion change your opinion on something
- 15:34The most adult sub-short will change in their minds or opinion on something which is which is difficult
- 15:39That seems to be part of our tribal evolutionary origins in a way you can't back down. Can we?
- 15:43Yeah, yeah, yeah, that becomes a difficult then it becomes a tribal thing doesn't it and you know and a face-saving thing as much as
- 15:53All of us you don't free to yeah exactly and I can dominate I can trump if I can use the word
- 15:58Yeah, yeah, yeah, yeah, yeah, yeah, we're sticking that down. Yeah, exactly
- 16:03Let's talk about education then Luke because it's interesting
- 16:05I I am now a very scientifically minded person and I'm fascinated by it
- 16:10But that was because in my teens I discovered Carl Sagan and Richard Dawkins and Richard Feynman and and my eyes were open through books
- 16:19Science at school. I hated it. It was all
- 16:22Petri dishes and you know, it was always sort of almost wrote learning and the table of the elements and everything
- 16:27What I loved being a sort of poetic humanities
- 16:30Nambi Pambi was the philosophy of science the majesty of science the poetry of science and I sort of wish that that got taught in school
- 16:38Yes, I strange. Yeah, I agree. I mean at the trouble is science is is is is full of facts is the problem
- 16:44You know, let's face it like I could describe the immune system to you and give you all these awful drive facts
- 16:49We'll bore the arse off you know, so so as an educator
- 16:53How do I make that interesting to kids? I still lecture in university. You see so but you're right
- 16:58That's that's this disappointing when that happens in a sense and again
- 17:02I'm a huge fan of science teachers in Ireland. I'm actually ready. It is Josh
- 17:05I'm president of the Irish science teachers
- 17:07Oh, lad
- 17:09Yeah, here we go
- 17:11Your pipe and you're not the president of the humility society of Ireland. No, no, no, not yes
- 17:19That's I'm aspiring to be that. Yeah, that's a long way to go yet
- 17:24My way together. Yeah, but no, I mean the and the science teachers are a great bunch
- 17:28I was at the conference two weeks ago, and this is the very thing they talk about
- 17:30How to make how to turn turn kids aren't as nice as ways to do it
- 17:34It sounds as if you had the a very unpleasant experience in a way
- 17:38Yeah, I mean maybe that wasn't unpleasant. There was just you know, it was just nothing. It was just blah
- 17:42I was just like what's inspiring about that strike. Yeah. Yeah, whereas I was lucky
- 17:46I had a great science teacher in school, which is with this the reason I became a scientist
- 17:50A guy called Tran Moon. He was the image of Shaggy and Scooby-Doo
- 17:53That was how I remember him and he really aspired me
- 17:56You know, so I was lucky in that sense
- 17:57You know, I'd good teacher in school
- 17:59Let's come back to the original question of what science actually is
- 18:02I mean you said that it was data, but let's put it in a historical context because people have had
- 18:06Information for a very long time and it's not it's not the case that simply accumulating
- 18:11Information is going to yield a strong scientific theory
- 18:15So what what comes first like the data or
- 18:18The theory and what makes a theory good?
- 18:21It starts with curiosity. You want to know something and it can be anything
- 18:25It can be dinosaurs stars science isn't the vote
- 18:28Discovered a new widget remember touch technology. So science is just the vote being curious and asking your question
- 18:35So you come up with the question and you try and answer it
- 18:37Now the way we answer questions usually is through experiments and we design experiments
- 18:41To help us answer the question and if the experiment then agrees with our hypothesis we get to a bottom line
- 18:46And then we say you know
- 18:48Ecos mc squared or whatever you want to call it you know
- 18:50So in other words that that's the scientific process and action and then the big question is what constitutes evidence
- 18:56And in my lab I need three or four independent lines of evidence to support the bottom line
- 19:01You know some allows might need one you know so it's about the strength of the evidence ultimately to support
- 19:07What the bottom line is about some particular aspect of the natural world
- 19:10And that really that really captures what the scientific process is about
- 19:13And it is all about the strength of the evidence and the the type of experiments you do
- 19:18That's why I teach you eight years of training really
- 19:20So eventually you want to become an independent scientist and design your own experiments
- 19:24That takes training you know takes a use of an effort read you super
- 19:27And then you can call yourself a card carrying scientist in a sense
- 19:30Because you can do you can do discovery stuff
- 19:32So it does take time to learn it's like an other skill reading
- 19:35What got you into it Luke?
- 19:37Well I'll say initially it was just the joy of us with the great teacher reading
- 19:41And then the one yourself just I began reading those books
- 19:43I remember reading Isaac Asimov
- 19:44He was a big hero as a teenager
- 19:47And he actually he's got science fiction over course
- 19:49But he also wrote the guide to science which I vividly remember reading
- 19:53At the age of 18 and I think I like this you know
- 19:56I think an element to me just was giving me
- 19:59That sort of reassurance maybe is one word for it
- 20:01To explain the the enormity of existence
- 20:04You know like I just enjoyed learning this
- 20:07What are you with Dawkins and he said I love Carl Sagan as well
- 20:10I mean those guys that's there about reading they're giving up
- 20:13We enjoy it because we get a sense of intellectual stimulation of course
- 20:17But secondly sense of wonder
- 20:19And then terribly it explains the complexity and enormity of things as well for me
- 20:24And that was a jump off point in many ways for me
- 20:26And did you find the fact that it explains things
- 20:28You just said it gave you reassurance
- 20:31I mean most Irish people get their reassurance presumably from their faith
- 20:35Was what was your
- 20:36Not anymore
- 20:37Not anymore
- 20:38That's the way it was the other
- 20:39You've never seen it in my lifetime
- 20:41You've never seen a country change
- 20:43It was as Ireland as a kid
- 20:44Yeah yeah
- 20:45It was 95% of observance of the Catholic faith
- 20:49Now it's about 10%
- 20:50You know that's got to go
- 20:52But you're right though yeah for decades here
- 20:54The church and religion
- 20:56For others say the same function anyway
- 20:57I don't see any difference there
- 20:59We're all human beings after all
- 21:01And someone used all their things to give them comfort
- 21:03For me I use science the way to think about you
- 21:05Was that a change? Were you raised religious?
- 21:08I was
- 21:09Yeah we all were
- 21:10Well they shot you you see if you didn't go
- 21:11It's not us a joke
- 21:15I wasn't like anybody else
- 21:17But I don't have a teenager
- 21:18And evidently I went
- 21:19What is this shit
- 21:20Yes no no
- 21:21I've got respect for people
- 21:22If that's their thing that's fine
- 21:24I'm going to shove it down my neck I don't mind
- 21:27But that was a funny one
- 21:28Yes so it started
- 21:29All of us went to that religious experience
- 21:31And then we came out the other end
- 21:32Hopefully relatively intact you see
- 21:35And when you say
- 21:36When you say you don't mind if people believe that
- 21:38As long as they don't shove it down your neck
- 21:40I mean the case of a Richard Dawkins or a Sam Harris
- 21:44Would be or a Christopher Hitchens
- 21:45Would be it they can't help but shove it down your neck
- 21:48Because there's something corrosive to the whole society
- 21:51Into the whole national or global conversation
- 21:54About people founding such fundamental ideas
- 21:58On unreasonable beliefs
- 22:00Or on a commitment to historical events
- 22:02That are so obviously
- 22:04Unlikely at best and ludicrous
- 22:06At worst
- 22:08Do you share that concern?
- 22:11I am inclined to more sympathetic towards people
- 22:14If they decide to believe
- 22:15It's certain things that's their business really
- 22:17You know and if it gives them to the nice
- 22:19That's fine by me you know
- 22:21Now if you're a scientist
- 22:23You got that coffee true
- 22:24Any of that
- 22:24Why would somebody believe that
- 22:26It becomes if it becomes malignant
- 22:28And begins harming others
- 22:29Then that's that's that's disastrous
- 22:31And we've seen that through history anyway
- 22:32And maybe that's where they're coming from
- 22:34In that regard
- 22:35Yeah well I think they also feel like it trains your mind
- 22:37To to get used to taking things on
- 22:40On two little evidence
- 22:41And to be rigorous about thinking
- 22:43So it makes it harder for us to
- 22:45Come to common solutions about things like the climate crisis
- 22:48If you're if you're sort of contaminated by the idea
- 22:51That you can just muddle along without thinking too carefully
- 22:54About the most fundamental things that you believe
- 22:57Well it's funny to say that yesterday
- 22:59Josh I saw a great someone sent me this poster
- 23:01Along the lines of
- 23:02Education is no good
- 23:03It destroys your faith in God
- 23:07So that kind of thing
- 23:09Yeah that's exactly right
- 23:10Yeah
- 23:10Again that's the malignant side of this innocent
- 23:13And I can see exactly where they're coming from
- 23:15The darkens will be of the viewers
- 23:17You know that it was all run
- 23:18A huge negative
- 23:19All this you see
- 23:20For lots of species on earth
- 23:21Kind of thing you see
- 23:22Yeah
- 23:23But that that that takes away from the fact that for many
- 23:25It's a very positive thing
- 23:26It can be very positive
- 23:28We humanism is one way to do it
- 23:30Plus Jesus or whatever
- 23:31You know so
- 23:32Do you keep the humanism far to can't argue
- 23:34You can't argue with that
- 23:34Ganya
- 23:35Yeah
- 23:36Yeah
- 23:37It's the other stuff that that's definitely a challenge you
- 23:40So if you were inspired to go into science
- 23:42By this science teacher
- 23:43How did you end up specializing
- 23:45Why did you end up an immunologist
- 23:47Yeah but then I said
- 23:49That's got one of the university
- 23:50Mainly to have a few beers
- 23:52And the usual kind of things
- 23:53And I picked science because I loved it from school
- 23:55And then I got drawn towards biology
- 23:57I mean to me biology is the ultimate science
- 23:59Because it explains life itself
- 24:01And that was the
- 24:02In the back of my mind
- 24:03Trying to understand life
- 24:04You know
- 24:04And then again just to
- 24:06I was in university
- 24:07And I began to specialize
- 24:08Just out of interest really
- 24:10Ended up an immunology
- 24:11Because
- 24:12I realized that the basis for most diseases
- 24:15Has a dysfunctional immune system
- 24:17You know at the background
- 24:17Somewhere
- 24:18So I feel like I'd be good to work on
- 24:19If I work in the immune system
- 24:21I might be able to help
- 24:22Come off with ways to treat diseases
- 24:24My first disease I worked on was Crohn's disease
- 24:26And I found what she built
- 24:28And then I moved into room with
- 24:29So I had arthritis and acne
- 24:30These are all diseases
- 24:31So the immune system goes crazy
- 24:32And begins attacking your own tissues
- 24:34Still on
- 24:34We still don't know why
- 24:35That's still the mystery
- 24:36They've got a lot of immunity
- 24:37So that got my imagination basically
- 24:40Here was a very complicated world
- 24:43Which I could do science in
- 24:45And make discoveries
- 24:46Which is my first thrill
- 24:47To make a discovery
- 24:48And then it'd be useful to design new medicines
- 24:50And that would be the ultimate dream
- 24:51And I still haven't got there yet
- 24:52So I'm still talking about
- 24:54And when you say that these kinds of diseases
- 24:56These inflammatory diseases
- 24:58We don't really know what causes them
- 25:00And we're not entirely sure how to cure them
- 25:03Do we? I have a close family member
- 25:04Who had ulcerative colitis
- 25:05Which is very similar to Crohn's disease
- 25:07So you'd be very familiar with that
- 25:08And you know
- 25:09Was on a powerful drug to combat it
- 25:12And gradually through lifestyle changes
- 25:14Was able to win himself off that drug
- 25:16And is now free from it
- 25:18What's happening there
- 25:20It's very difficult
- 25:21So I mean I've been working on these things
- 25:23For over 35 years now myself
- 25:24You know
- 25:25We still don't really know
- 25:26It's a shocking thing
- 25:27We've learned a bit about the component parts
- 25:29Of the immune system to go wrong
- 25:30So we know some of the
- 25:32The sort of that
- 25:33You know cell types
- 25:34And some of the chemicals
- 25:35The immune molecules that are made
- 25:37You know
- 25:38They're overproduced in these diseases
- 25:40So one idea would be to block those
- 25:41And ramp them down
- 25:43You might relieve some of the symptoms
- 25:44Not that the drugs do
- 25:45But you're right though
- 25:46We've no way to stop it starting
- 25:48We've no way of predicting its course
- 25:50When these disease either
- 25:51So these are still big mysteries
- 25:53And again very active
- 25:54They're still important
- 25:56Because they're so common
- 25:57And it's also debilitating
- 25:58Because you would know
- 25:59From your own
- 26:00Connections there
- 26:01So we need
- 26:02We need to do better
- 26:03And now there has been advances
- 26:04In rheumatoid arthritis
- 26:05It was a huge advance in the 30 years
- 26:07They did discover new ways
- 26:09To block some of these mediators
- 26:10Like go crazy in that disease
- 26:12You don't see people having wheelchairs
- 26:14Anymore on rheumatoid
- 26:15Where you did when I started
- 26:17So there has been some progress
- 26:18But we do need to stop them at sorcery
- 26:20And another example
- 26:21Josh is a big breakthrough
- 26:23About a month ago
- 26:23As MMS might be caused
- 26:25By Epstein-Barravars
- 26:26Now if that's true
- 26:28Oh yeah
- 26:29You can no vaccinate
- 26:30Of course against MS
- 26:31With nothing tremendous
- 26:32You know
- 26:32Oh wait
- 26:33And we're not going to be vaccinated
- 26:34Against that already
- 26:35No
- 26:36No
- 26:36No
- 26:36And it's a mystery
- 26:38It's very common
- 26:38Epstein-Barravars
- 26:39We've all probably had it
- 26:41It causes, I think, a glandular fever
- 26:43If you're a teenager
- 26:44If kids pick this up
- 26:45You know
- 26:46But for some reason
- 26:47With the right
- 26:47Drone genetic background
- 26:49Combined with that virus
- 26:50You might develop MS
- 26:51So is the suggestion
- 26:53That the glandular fever could trigger MS initially
- 26:56Or that if you've had glandular fever in the past
- 26:58You're susceptible to it
- 27:00No
- 27:00No, it looks as if
- 27:01Like most people have had Epstein-Barravars
- 27:03And yet MS
- 27:04Is not common
- 27:05I mean it's maybe one or two
- 27:06Persons in Ireland
- 27:07Which is quite high
- 27:08So
- 27:09It'll be a combination of your genetic background
- 27:11Then you get infected
- 27:12And that might progress into MS
- 27:14I'm just trying to figure out
- 27:15If I'm at higher risk
- 27:16If I can get vaccinated
- 27:17Or if I'm at higher risk
- 27:18Because I have had the virus
- 27:20But
- 27:21For 15 years
- 27:23Right, no
- 27:24I don't want to worry about that
- 27:24If you haven't got infected
- 27:26We don't know
- 27:27I mean it's MS can develop later in life
- 27:30This discovery
- 27:30There's a massive analysis happening now
- 27:32Of course
- 27:32To see this holds off
- 27:34You see
- 27:34It's a bit like
- 27:35Human papaloma virus
- 27:36And survival cancer
- 27:38There's a vaccine for that
- 27:39It's discovered Australia
- 27:40By the way
- 27:40You know
- 27:40Yeah
- 27:42That was a great discovery
- 27:43That vaccine
- 27:44Now not not everybody
- 27:45You get to HIV-V to develop cancer
- 27:46So it's a bit like that
- 27:47You know
- 27:47So I say
- 27:48Something else going up
- 27:48There's something else happening
- 27:50Wasn't there also a breakthrough
- 27:50A similar breakthrough with ulcers
- 27:53There was
- 27:54That other famous Australian
- 27:55Dip terror
- 27:56I give the Aussies credit
- 27:57So it's horrendous
- 27:58Now it's just a crying out loud
- 28:00Not only we got exposure
- 28:01But you know
- 28:02Also
- 28:03Inflammatory
- 28:04It was being judged
- 28:05And this isn't the blood
- 28:06Smoke up your country's ass
- 28:07Necessarily
- 28:08But it
- 28:08There's been fantastic
- 28:09Immunality in Australia for decades
- 28:11You know
- 28:12And we're all on our off
- 28:12The taste of the wee high
- 28:14The water lies the hall
- 28:14Is the student male
- 28:15And that's a world-class place
- 28:17For that major discoveries
- 28:18Or made there
- 28:19That have contributed directly to human health
- 28:21Which is my dream to love yourself
- 28:23Yeah, we're not all crocodile dandies
- 28:25You know, so that's right
- 28:26That's right
- 28:27Yes, yes
- 28:28That's right exactly
- 28:29But probably, Marcia, he's a hero
- 28:31As you know, because nobody believed him
- 28:33A true maverick
- 28:33Again, we love that
- 28:34You know
- 28:34And he proves in himself
- 28:36By taking this bacteria
- 28:37Helicopacter
- 28:38So just explain it to people
- 28:39Because not everyone will know this
- 28:40So ulcers back in the day
- 28:42And my dad had ulcers
- 28:43This was supposed to be some kind of a
- 28:44Stress-related thing
- 28:46Or you know
- 28:46Some sort of a mystery
- 28:48And when someone, when this Aussie
- 28:49Proposed that there might be a bacterial
- 28:52Cause
- 28:52That was considered to be ludicrous
- 28:54But what happened?
- 28:56Yeah
- 28:56Well, exactly
- 28:57When I was younger
- 28:59And also was a middle-aged man
- 29:00Too many martinis
- 29:02Wasn't meeting his sales targets
- 29:04Smoked him
- 29:04What you got
- 29:04And also
- 29:05That kind of the
- 29:05You know
- 29:06But whatever
- 29:07And Marcia was in the hangar
- 29:09I mean
- 29:09There's a bacteria here
- 29:10Because he'd go back to a pylori
- 29:11Funny name
- 29:12That was the bacteria he identifies
- 29:14In the stomachs of people with ulcers
- 29:16And that kind of just
- 29:17That could just be a
- 29:18You know, a carative thing
- 29:20Didn't have to be causative
- 29:21And then he proves
- 29:21It's this bacteria
- 29:22That irritates the
- 29:24The digestive system
- 29:24And brings out ulcers in the stomach
- 29:26Astring ulcers
- 29:27You know
- 29:27And to prove it
- 29:28He eventually took
- 29:29Drank someone's self
- 29:31And he gave himself an ulcer
- 29:32You know
- 29:33So
- 29:33No
- 29:33And he took
- 29:34Hydrosandibiotics
- 29:36Killed it
- 29:36And they also went away
- 29:37And that was
- 29:38That was
- 29:38And he was warned as we call this
- 29:39But
- 29:40Yeah
- 29:40So
- 29:41We needed more clinical trials
- 29:42But it was proven
- 29:43And this is a revolution
- 29:44He won the Nobel Prize party for this
- 29:46It was a very painful
- 29:48Horrible disease
- 29:49You know
- 29:49People drink a milk
- 29:51To try to balance the acid
- 29:52All this stuff
- 29:53No, it changed my dad's life
- 29:54When that breakthrough happened
- 29:55Oh yeah
- 29:56Exactly
- 29:57So we love that
- 29:57That's a great
- 29:58That's one of my best examples
- 29:59Of how great science is
- 30:00And it's such
- 30:01You know, an idea
- 30:02Hypothesis
- 30:03Test it
- 30:03Get data
- 30:04Back it up
- 30:05A press
- 30:05Though
- 30:06Millions of people don't suffer
- 30:07As much as they did before
- 30:08Because
- 30:08I know
- 30:09Nobody can
- 30:09There's no misinformation
- 30:10With this one
- 30:11You know
- 30:11Not only
- 30:12Not only
- 30:12No, that's right
- 30:13There it is
- 30:13There's the facts
- 30:14In front of the
- 30:15Yes
- 30:16And so then the human
- 30:18Human problem of virus
- 30:19As you said as well
- 30:20And cervical cancer
- 30:21Yeah
- 30:21That connection was made
- 30:22Now you're saying that there might be
- 30:24A connection that's being made
- 30:25Between Epstein bar
- 30:27And MS
- 30:28Yes
- 30:29That's right
- 30:29I'm still unclear as to whether or not
- 30:31You're saying that
- 30:32We need to vaccinate people
- 30:33Who've never been infected
- 30:35With Epstein bar
- 30:36Because
- 30:37That would reduce their risk
- 30:39Or even if you have had a vaccination
- 30:41Would still reduce your risk
- 30:43Unlikely
- 30:44Yeah
- 30:44Had it probably too late
- 30:45But we don't have anything
- 30:46We don't
- 30:46Well, it might be possible
- 30:47But the idea would be
- 30:48If this holds up
- 30:49Josh in a sense
- 30:50We will be vaccinating teenagers
- 30:52Against Epstein bar
- 30:53Virus
- 30:54And MS might go away
- 30:55Wouldn't that be tremendous
- 30:56I don't believe it's more
- 30:56I also have a
- 30:57We need more data
- 30:58Recently diagnosed with MS
- 31:00It's quite
- 31:00Yeah
- 31:01And
- 31:02Exactly
- 31:02Well
- 31:03I was a devastating
- 31:04Devastating disease
- 31:05Now again
- 31:05There's been progress with MS
- 31:06When I began my research
- 31:08I was I say 30 years ago
- 31:09There was
- 31:09No, it was nothing for MS
- 31:11There's three or four options now
- 31:12And they do help some people
- 31:14You know, not everybody
- 31:15So there has been a bit of progress there
- 31:16But if this turns out to be the case
- 31:18MS could be a thing of the past
- 31:20Which would be tremendous
- 31:20Wow
- 31:21So when you think about this
- 31:22There are other things
- 31:23There are other ailments
- 31:24That you suspect
- 31:25Might have a viral bacterial cause
- 31:27That we just don't know yet
- 31:29Yeah, we're looking for them
- 31:31I mean
- 31:31What idea would be
- 31:32All these diseases
- 31:33Are caused by an infection
- 31:34And that sets the immune system
- 31:36Off-kilter
- 31:36Basically
- 31:37And then begins to
- 31:38Attack our own tissues
- 31:39Is the idea here
- 31:40And often when you end up
- 31:41When your doctor's surgery
- 31:43You've cleared the infection
- 31:44You see
- 31:45But the immune system is still burning away
- 31:47You know
- 31:47And it's right
- 31:48Re-re-re-calibrated
- 31:49That's where I saw
- 31:50It's too
- 31:50So you won't find the damn thing
- 31:51But you know
- 31:52For the MS study
- 31:53They taken samples of 18, 19-year-olds
- 31:56It was in the U.S. Army strange
- 31:57Right
- 31:58And everybody gives a blood sample
- 32:00And when they sign up
- 32:01Basically
- 32:02You know
- 32:02They went into the archival material
- 32:04And then
- 32:05It's tried to figure out
- 32:05Who went on to develop MS
- 32:07And saw this correlation
- 32:08Then with F-Sign Barbar
- 32:09So it was very retrospective in a way
- 32:11You know
- 32:12Pretty clever
- 32:12Wasn't it to do that in a sense
- 32:13You see
- 32:14So that's the kind of thing
- 32:15But the trouble is
- 32:15As I say
- 32:16When often with these diseases
- 32:18You're trying to shut the stable door
- 32:19After the horse's bolt
- 32:20And you're waiting to try to find
- 32:21In that
- 32:21You know
- 32:22But still
- 32:23There's this reason
- 32:23What I thought this is
- 32:24Maybe they're all caused by viruses
- 32:25All these disease
- 32:26You never know
- 32:27No again
- 32:27We do more evidence
- 32:28But I thought there's nothing
- 32:29On the reason
- 32:29What I thought this is
- 32:30Well certainly
- 32:31I mean
- 32:31Are you just talking about diseases
- 32:32That are
- 32:33That involve the immune system going haywire
- 32:36Yeah
- 32:37It's exactly
- 32:38So
- 32:38I mean
- 32:39This is also a problem with COVID
- 32:40As well
- 32:40Just to loop back to that
- 32:41Obviously
- 32:42That
- 32:42You know
- 32:43When
- 32:43When COVID
- 32:44Does you in
- 32:45And frequently
- 32:46Especially in the cases
- 32:47Where younger people
- 32:49Die from COVID
- 32:50And correct me if I'm wrong
- 32:50It's because
- 32:51Their immune systems are going
- 32:52Absolutely berserk
- 32:53And they've got this
- 32:54Is it a cytokine storm
- 32:55That just
- 32:55That's exactly right
- 32:56Throwing the system out
- 32:57Precisely
- 32:58Now there's a great word
- 32:59For me
- 32:59Just
- 33:00I work on cytokines
- 33:01I've worked on them
- 33:02Since the mid
- 33:0380s really
- 33:03You know
- 33:04And many are these
- 33:05Discovered cytokines
- 33:06I'll have that
- 33:07Especially
- 33:07We are
- 33:08Yes
- 33:08There you have it
- 33:09Basking in the
- 33:10In the inherited glory
- 33:11For a countryman
- 33:12And they go
- 33:12Well
- 33:13Well let's get
- 33:14To get the message out
- 33:15Australia's
- 33:15Contributions
- 33:16To the world of cytokines
- 33:17To be massive
- 33:18Over the honest
- 33:18I got them
- 33:19I'm not making it up
- 33:19So
- 33:20So it's great
- 33:21You know
- 33:21And you're right
- 33:21But this
- 33:21This so-called cytokine storm
- 33:23cytokines
- 33:24So basically
- 33:24The messengers of the immune system
- 33:26And they
- 33:26When you have an infection
- 33:27They go up
- 33:28Wake up the immune cells
- 33:29So it's then
- 33:29Clear the infection
- 33:30That's the way the immune system works
- 33:31You know
- 33:32The trouble is
- 33:33And you get too many cytokines
- 33:34The dreaded
- 33:35Military
- 33:36Andology friendly fire
- 33:37You know
- 33:38You get collateral damage
- 33:39And then you get all the
- 33:39Symptomology
- 33:40And COVID is exactly like that
- 33:42And in general we call this
- 33:44Sepis the cause
- 33:44In the case of bacteria
- 33:46In fact, same
- 33:46And I think
- 33:47Out of control
- 33:47Immunable
- 33:48Why happened to the mystery
- 33:49Oh no, I thought
- 33:50Sepis was just
- 33:51That the bacteria
- 33:52Was getting to
- 33:53To strong a foothold
- 33:54In you
- 33:55I didn't realize
- 33:55That it was an immunological response
- 33:57Oh absolutely
- 33:58Sepis is again
- 33:59An overactive immune
- 34:00Response to bacteria
- 34:01That goes
- 34:02Systemic
- 34:03As aware
- 34:03And then you're
- 34:04Livered
- 34:04And you're long
- 34:04And everything gets affected
- 34:05You know
- 34:06And then
- 34:06Sepis is still a lethal condition
- 34:08You see
- 34:08And again we're trying to
- 34:09Why I walk into that
- 34:10That's trying to stop
- 34:11That's almost impossible
- 34:12As soon as they think
- 34:13The trains are so run
- 34:14It's almost
- 34:15Then possible to stop
- 34:16But you see
- 34:16The COVID is
- 34:17Do you think that COVID is
- 34:18The long COVID is a good example
- 34:20Jewish
- 34:20Because
- 34:21That seems to be the immune system
- 34:23Of kilter
- 34:24And persisting then
- 34:25From from months
- 34:25And even years
- 34:26It looks like
- 34:27They're in some people
- 34:28They've awful symptoms
- 34:29That go on
- 34:29For months and months
- 34:30And again
- 34:30The virus now gone
- 34:31Remember more than likely
- 34:33Yes
- 34:33Instead the immune system
- 34:34And reset you see
- 34:35Is now been flipped
- 34:36To give you those symptoms as well
- 34:38That's funny isn't
- 34:39I hadn't really thought about that
- 34:40There is no virus
- 34:41There is no COVID virus left in you
- 34:43When you've got long COVID
- 34:44It's you
- 34:45That's right
- 34:45Doing it
- 34:46Is there a way
- 34:47If all of this has to do
- 34:48With an overreaction of our
- 34:50Immune system
- 34:50So many of these different
- 34:52ailments
- 34:53Then rather than playing a game of
- 34:54Wacomole
- 34:55And sort of trying to
- 34:56Hit each one
- 34:58By either devising a vaccine
- 34:59To take
- 35:00To prevent you from
- 35:02You know
- 35:02From being infected with
- 35:03Whatever that
- 35:04That bug is in advance
- 35:06Or a treatment after
- 35:07You have been infected
- 35:09Could there be any
- 35:10Grand sort of
- 35:12You know like
- 35:12Physicists want something
- 35:13That's just printed on the t-shirt
- 35:15That is the
- 35:16You know the
- 35:16The grand equation
- 35:18Could there be a way of
- 35:18Regulating
- 35:19The immune system
- 35:20So that it just doesn't go
- 35:22There aren't these spikes and troughs
- 35:24The could the could well be
- 35:25In fact one of the big advances
- 35:27In the past
- 35:27They ten years
- 35:28Is to find those key
- 35:29Nodes
- 35:30They're going to call them
- 35:30You know
- 35:31The master switch
- 35:32That gets flipped
- 35:33You see
- 35:34And then get reversed
- 35:34That master switch
- 35:35You could have
- 35:36Have a treatment for many different diseases
- 35:38We know this
- 35:39For example
- 35:39Stereoids work in many
- 35:40In the family disease
- 35:42So they
- 35:42They seem to
- 35:43Control this central
- 35:45So the switching mechanism
- 35:46That's got that's come crazy
- 35:47And our
- 35:48Stereoids work in asthma
- 35:49They're working colitis
- 35:50They work in skin diseases
- 35:52For that reason
- 35:53Now we don't have to know more
- 35:54About how
- 35:54Stereoids work
- 35:55By the way
- 35:55That's still a bit
- 35:56A bit of an unknown
- 35:57But certainly
- 35:57You're right
- 35:58That kind of evidence
- 35:58What suggest there is some way
- 36:00To reset the whole thing
- 36:01Which could be then used
- 36:02For across all these diseases really
- 36:04Could there be a utility
- 36:05In taking
- 36:06Lotus
- 36:06Stereoids
- 36:07I mean, I sometimes get hives
- 36:08When I
- 36:09You know, when I eat some
- 36:10Weird things
- 36:11I'll
- 36:11You know, just have some
- 36:12What sort of look like
- 36:14Mosy bites
- 36:15On my body
- 36:15And if I pop a couple of steroid
- 36:17Tablets
- 36:17Like a
- 36:18You know, I mean
- 36:19Obviously
- 36:19We're not talking about
- 36:20Like human growth
- 36:21Home
- 36:21Home
- 36:22Stereoids
- 36:22We're talking about
- 36:23Anti-algae pills
- 36:25Then it goes away
- 36:26In the same way
- 36:27That we
- 36:28We expect that there's
- 36:29Probably a positive outcome
- 36:30On your heart
- 36:31If you take a half an aspirin
- 36:32A day
- 36:33Could there be
- 36:34A similar case to
- 36:35To be made for steroids
- 36:37But again, the history
- 36:38Of that's a great one
- 36:38When that was discovered
- 36:39In the 50s
- 36:40There was a guy called
- 36:41Hensch
- 36:41He was a rheumatologist
- 36:42He noticed a woman
- 36:43When they go pregnant
- 36:45The arthritis went away
- 36:46If they'd rheumatized
- 36:47And he wondered why
- 36:48And he knew there was changes
- 36:49In these steroids
- 36:50Your own pregnancy
- 36:51And he got one of the steroids
- 36:53A glucose chord
- 36:54A chord
- 36:54Gave it to a man
- 36:55And that guy's arthritis went away
- 36:57And they all thought
- 36:58Wow, we've now got a way
- 36:59To cure arthritis
- 37:00You know
- 37:01So it's a great hope
- 37:02But the trouble is the side effects
- 37:03Stereoids do many different things
- 37:05In your body
- 37:05They don't just suppress
- 37:07The inflammatory process
- 37:09So again, they can't be used routinely
- 37:10Because they get skin thinning
- 37:12And various other things happen sadly
- 37:13You see
- 37:14And that can happen in science
- 37:16So you think you've cracked it
- 37:17And then some little dirty fact crops
- 37:19Or you see
- 37:19So you can all know
- 37:20You know
- 37:21Then you've got to back to square what
- 37:22But steroids are very useful
- 37:24Especially in their acute inflammation
- 37:25If you're a massive inflammatory reaction
- 37:27Some steroid will give you relief
- 37:28Then in fact an asthma is a good example
- 37:30That disease
- 37:31Stereoids are used
- 37:33To treat severe asthma for that reason
- 37:34Because they can dampen
- 37:35They put the fire out
- 37:36But the trouble is they've got these
- 37:38You can't use them chronically
- 37:39Because they've got these
- 37:39Or the other effects
- 37:40That are just to do with inflammation
- 37:42Extraordinary stuff
- 37:43Do you suspect that they're just
- 37:45To take a completely different pivot
- 37:46While we're talking about biology
- 37:47How widespread do you think
- 37:49The biological systems are
- 37:50In the universe
- 37:51Do you think about that?
- 37:53I do
- 37:54Oh yeah, well I always
- 37:55Like as I'm half you see
- 37:56That's the difference
- 37:57The side science
- 37:58Fiction to peasant and warner space
- 38:00Or to see what's not a great idea
- 38:01At the aliens
- 38:02Have governed our evolution
- 38:04In a way
- 38:04You know
- 38:05So I mean there has to be life
- 38:07Outside the earth
- 38:08It's just the loves to
- 38:09Average is basically you know
- 38:11There's billions and billions of galaxies
- 38:13Isn't there and there's lots of planets now
- 38:15I mean the big breakthrough in astronomy
- 38:16Was the discovery of these exoplanets
- 38:19That are in the right kind of gold
- 38:20You locks his arm as they call it
- 38:22So more than likely
- 38:23Then we will find
- 38:24Well when we find us
- 38:25The next question
- 38:26But I wouldn't be at all surprised
- 38:27If life has evolved
- 38:28In other parts of the universe really
- 38:31Do you think that consciousness has
- 38:32Yeah, possibly
- 38:34Yeah, that's that's that's that's mind you
- 38:36And that is the central question in all biology
- 38:39Now what is consciousness
- 38:40So we said of no clue
- 38:41Terrifyingly
- 38:42Hmm spider what
- 38:43And there's a few clues having said
- 38:44That there's a bit of progress
- 38:45But uh
- 38:46But still that that's that's the greatest
- 38:48The brain the mind
- 38:49Remains the greatest scientific
- 38:50And one of them already
- 38:52And when we can't get near it
- 38:53It might be judge either
- 38:54With a conference in Dublin in 2018
- 38:56Addressing this
- 38:57And all the right neurosiders came
- 38:59And even at the end of that
- 39:00We said
- 39:00We scratched our heads literally
- 39:02And said what the hell is this about
- 39:03You know, it's that
- 39:03Yeah
- 39:04And we consciousness is a product of biology
- 39:06Remember so
- 39:08If there is a biological system elsewhere
- 39:10Consciousness more than likely
- 39:11Will be part of everything
- 39:13Well is it a consequence of biology
- 39:15I mean this is interesting
- 39:15I've just been having a conversation
- 39:17With Toby Walsh
- 39:18Here in Sydney on my radio show
- 39:19Who's an artificial intelligence expert
- 39:22He's got a new book out about AI
- 39:23And you know he was sort of saying
- 39:25The same thing that you just did
- 39:26Which is it's impossible to know
- 39:27Whether or not machines will be conscious
- 39:29Because we don't even know why we're conscious
- 39:31Yeah
- 39:32But if we
- 39:33I mean if you're not religious
- 39:34And you don't think that we have a soul
- 39:36And you think that
- 39:38You know animals
- 39:39Most animals at least are conscious
- 39:41That there's something
- 39:42That it's like to be them
- 39:43As a result of what's going on inside their skulls
- 39:46That there's some kind of
- 39:47Complicated information processing going on
- 39:49That is causing consciousness to arrive
- 39:52The sense of being alive to arise
- 39:54Then why couldn't an equally
- 39:56Sophisticated network of information processing
- 40:00Yeah
- 40:00That's made out of silicon and microchips
- 40:03Be conscious
- 40:04Exactly
- 40:04That doesn't have to be biological
- 40:06You know
- 40:07It's chemical
- 40:07Let's put it that way
- 40:08Yeah
- 40:09Right
- 40:10And you can make a chemical system
- 40:11That's a machine
- 40:13Can't you
- 40:13But it's so complicated
- 40:14It's almost impossible to envision you to see
- 40:16I think we're like
- 40:17You know the great analogy is
- 40:19Like it had aliens could be among us
- 40:21We can't even see them
- 40:22Like when it ends
- 40:24When it ends crawls on your aboot
- 40:26That answer doesn't know what you exist
- 40:27Does he
- 40:28And yet you're there with the ads
- 40:29You know what I mean
- 40:30Yeah
- 40:31They could be hiding
- 40:32We're like
- 40:33Yeah, we're like ants crawling on
- 40:35Some big creatures boot at the moment
- 40:37Basically
- 40:38You're tough in the country
- 40:38This kind of thing you see
- 40:40So
- 40:40I mean it's such an interesting topic
- 40:42There's obviously
- 40:43And there is lots of research happening
- 40:44The closest we've got to it
- 40:45By the way
- 40:46I think it's at N grams
- 40:48It's about ENG or AMS
- 40:50They are interesting
- 40:50That'll networks of neurons in the brain
- 40:52And they seem to have some kind of emergent property
- 40:55But still they were a long way off
- 40:56Understanding these comments
- 40:58In my opinion
- 40:58I don't know if they should be told
- 40:59What do they look?
- 41:00What are ENG grams?
- 41:01ENG grams
- 41:02They're very complex kind of
- 41:03And neural networks
- 41:04There's the best way to describe them in the brain
- 41:07And you can manipulate them
- 41:08And create false memories
- 41:10Amazingly
- 41:11By targeting these pathways
- 41:12For instance
- 41:13So we know
- 41:13Memory is a key part of consciousness
- 41:15Of course
- 41:15So there's lots of work going
- 41:16And I'm not a neuroscientist
- 41:18I endanger myself now
- 41:20But I think the way in regard
- 41:21But I'm very interested in this
- 41:23No more than anybody else
- 41:24So ENG grams
- 41:26They reckon
- 41:27Some of the closest
- 41:28We're getting to understanding memory
- 41:30For instance
- 41:30And memory is a key part of consciousness
- 41:32Yeah
- 41:33What happens when you lose your memory
- 41:35But you still have consciousness in dementia
- 41:37But
- 41:37The great question
- 41:38Yeah, that's very good
- 41:40Yeah, that's a good point
- 41:40The people who memory sadly
- 41:42They're diseases
- 41:43So we need progress
- 41:44I mean
- 41:45Remember there's a desperate need
- 41:46For better inside cell cybers
- 41:48For instance
- 41:48And again there's big, big effort happening
- 41:50The really good question
- 41:51That clearly memory begins to go
- 41:53Why do we remember stuff from childhood
- 41:55Not from later in life
- 41:56For instance
- 41:57So
- 41:58And you know
- 41:59That's the case with dementia as well
- 42:00You can't remember what you did
- 42:01Very much to go
- 42:02But you can totally remember
- 42:03What you were doing in your five years old
- 42:06It's weird
- 42:06So whatever was laid down there
- 42:08Must have been so durable
- 42:10In a way
- 42:10It still persists
- 42:11You see
- 42:12Whereas more recent memories down
- 42:13So again
- 42:13That's another big mystery
- 42:15But
- 42:15But that's an area that's so important
- 42:17Because as we get older
- 42:18As we know the aging population
- 42:21Dimension will go off a lot
- 42:23And it's such a heartable disease for people
- 42:24So again we'd like to see progress there
- 42:26Basically
- 42:27You know
- 42:27That's my clarion call
- 42:29They're from a scientist
- 42:30And gets stuck in
- 42:31And this is going to make something interesting
- 42:34Have you heard the case look of the guy
- 42:35I think he was a composer
- 42:37Who had the most severe case of
- 42:40Amnesia ever recorded
- 42:42I think
- 42:43I come up with what happened in a stroke or something
- 42:45And his brain would almost completely reset
- 42:48Every five or six minutes
- 42:50So that he was almost like he was waking up
- 42:52Into an entirely new universe
- 42:55And his wife has written a book about it
- 42:57Which I really want to read
- 42:58But he would
- 42:59You know he got to the point where he had a note book
- 43:01A diary
- 43:02And it was
- 43:03It would be full of sentences like
- 43:06This is the real me now
- 43:09This is me now
- 43:10And that would be scribbled out
- 43:11And then underneath it would be like
- 43:12No, no, no, this is me
- 43:13That was not me
- 43:14This is the real
- 43:15This is the true me
- 43:16God
- 43:16And that would be scribbled out
- 43:17It sounds like
- 43:18And it's just
- 43:19It makes you wonder
- 43:19It makes you wonder
- 43:20Who are you when you don't have content
- 43:23Well, that's right
- 43:24Yes, you'd wonder what's changing in his brain
- 43:26In a sense
- 43:27Wouldn't you
- 43:27Would that could be imaged in some way
- 43:28The big advance in neurobiology
- 43:30Was the invention of the
- 43:32Function of MRI machine
- 43:33And follow bits of the brain
- 43:34Working and changing and so on
- 43:36You know, that was the huge advance
- 43:37For you know
- 43:38But in fact
- 43:38In fact, that would be
- 43:39That person would be a great subject of study
- 43:41Wasn't they?
- 43:42Yes
- 43:43Except every five minutes he'd be
- 43:44Trying to be
- 43:45Wouldn't know why he's in an MRI
- 43:46You'd see
- 43:47That's the way he's saying
- 43:48He gets exactly
- 43:49Yeah
- 43:49He gets exactly
- 43:49Yeah
- 43:50Yeah
- 43:50And was this personality changing every five minutes as well
- 43:53What a terrifying prospect
- 43:54Yeah
- 43:55I don't think it was
- 43:56Yeah, I don't think it was
- 43:57It was the same guy
- 43:58But you know
- 43:59All of a sudden just had no
- 44:00No
- 44:01No
- 44:02Past
- 44:03Right
- 44:04So just
- 44:05Pivoting back to your field of expertise then
- 44:07What's the basic
- 44:08Like can you just explain
- 44:10What our immune system is actually doing
- 44:11I don't have
- 44:12For me the immune system is just a metaphor
- 44:14Like when I talk about
- 44:15The vascular system I can picture
- 44:17Vains and arteries
- 44:19And like when we talk about other
- 44:21Aspects like I sort of have an image in my head of
- 44:23The DNA double helix or something like that
- 44:25But the immune system
- 44:26Like what actually is it
- 44:29Yeah, it just blows in different cell types really
- 44:31That that's where the complexity comes from
- 44:32I began the first studies began in the early sort of 20th century
- 44:36When they begin to notice
- 44:37To put begin white blood cells
- 44:39Going into sites of infection
- 44:40And what are those white blood cells
- 44:42What do they do and you know
- 44:43And then scientists began to study these cells
- 44:46And they began to realize
- 44:47That the cells were making interesting things
- 44:49Antibodies
- 44:50Being a great example
- 44:51They kind of lock on to a bacteria
- 44:53And kill it say
- 44:54Or allow the immune system to digest it in various ways
- 44:57So it's a very complex network of different cell types
- 45:00Making sort of
- 45:01You know sort of
- 45:02I guess weapons and making ammunition
- 45:04And making all kinds of things
- 45:06To fire at the infectious agents
- 45:08So it evolved basically to fight bacteria virus
- 45:11As a parasites and so on
- 45:13Reliced it is complex
- 45:14Because it has to be regulated very carefully
- 45:16As we just discussed
- 45:17Because it goes out of control
- 45:19It is like an army
- 45:20We use that analogy a lot actually
- 45:22You know
- 45:22And then you have a war against the invader
- 45:25And you clear the invader
- 45:26With all your weapons
- 45:27And your machinery and all that
- 45:29Sometimes it becomes a civil war
- 45:31Where the army attacks your own tissues
- 45:33Is the way to think of it you see
- 45:34So the army is the best metaphor we have really for us
- 45:37I mean I'm across all the metaphors
- 45:39But I'm not across what's actually happening
- 45:41So I had COVID a few months ago
- 45:44As many many people have in the past year
- 45:46I was a triple-vaxed
- 45:49It was mild
- 45:50But what's actually happening when
- 45:52So I'm feeling
- 45:53Like I'm feeling really tired
- 45:55When I start getting COVID
- 45:56And I start thinking
- 45:57Oh this isn't great
- 46:00What if you zoomed in on a particular part of my anatomy
- 46:04Would you be able to see a virus
- 46:07Would you be able to see my cell
- 46:09A cell of mine doing something physically to a
- 46:12Absolutely
- 46:12Actual virus
- 46:14We could indeed
- 46:14And we can see exactly what's going on
- 46:16And we can read
- 46:17We can do that in a lab as well
- 46:18By taking cells and infecting them
- 46:20We use that as a model obviously
- 46:21As well as infecting people
- 46:23But we can take animals and infect them
- 46:25And we can see the virus
- 46:26So we can see the immune system
- 46:27Taking up the virus
- 46:28What happens is the virus
- 46:30The first step in the process
- 46:31Is the immune sense of the virus
- 46:33Your immune cells are bristling with sensors
- 46:36To try to look for viruses basically
- 46:38And the main way we sense this virus
- 46:40Is through sensing its RNA
- 46:41Because I do not know just the RNA virus
- 46:43There are sensors in your body
- 46:45To pick up on the RNA
- 46:46And latch onto it literally
- 46:48You know
- 46:48One is called a regi
- 46:50For it's
- 46:50And that's in every cell in your body
- 46:52If the virus is there
- 46:53The regi detects it
- 46:55And that's the alarm now
- 46:56It's always the virus
- 46:57Intruder you see
- 46:58And the regi then turns on a set of genes
- 47:00That are immune genes
- 47:01That begin to combat the virus
- 47:03A very good example
- 47:04I think something to fear on us
- 47:05And again, dare I say the Aussies
- 47:07Have made discoveries in interference as well
- 47:10In fact, I shout out to one of the best mates
- 47:12Paul Herzog is in Monash
- 47:14She's been a working on interferons for years
- 47:15For us
- 47:16You know what?
- 47:16So the interferon
- 47:17They get made
- 47:18Interferons get made
- 47:19And guess what they do
- 47:20They stop the virus replicated
- 47:22They're a great thing
- 47:23You know
- 47:23Because the virus can't divide
- 47:24If you stick interferons on the cell
- 47:27It shuts down the cell's machinery
- 47:28That the virus hijacks by the way
- 47:30You might know
- 47:30The virus is very simple
- 47:32Hasn't got many genes
- 47:33And hijacks are
- 47:34Our own bodies in a way to copy itself
- 47:36The interferons stop all that
- 47:38And that's why kids are so resistant by the way
- 47:41Because kids make a massive amount of interference
- 47:44So if a child in hails the virus
- 47:45In the robot airways and their noses
- 47:47Then they make a huge amount of interferon
- 47:49And that stops the virus
- 47:50And it tracks the cat to bite
- 47:51And as you get older
- 47:53The reason my older people are susceptible
- 47:55Is your immune system begins to go off the boil
- 47:57Like making parts of your body
- 47:58Yeah
- 47:58You know
- 47:59And now the virus is to foothold
- 48:00And we know the interferon response
- 48:02That's one example
- 48:03Judging away
- 48:04But I can give you loads of it
- 48:05But again, Peter Darkey
- 48:07A Nobel Prize winning Australia
- 48:09And remember
- 48:09Who went over
- 48:10He was the guy
- 48:11Who discovered
- 48:12How the immune system presents bits of viruses
- 48:15To see it
- 48:16You know
- 48:16So
- 48:17So they think of the MHC
- 48:18It's called
- 48:19You know
- 48:19And they latch onto the virus
- 48:21They take a piece of it
- 48:22And show it to the T cells
- 48:24The T cells are very important
- 48:25To cells over the immune system
- 48:27Peter got the Nobel Prize
- 48:28Because before his discovery
- 48:29We didn't really know that part of it
- 48:31You know, how bits of virus were being shown
- 48:33As aware to the key troops
- 48:35So it was
- 48:36And then
- 48:37And Peter was discovery was so important
- 48:38Because I gave us a big insight
- 48:40Into how the immune system sees viruses
- 48:42This happens with COVID
- 48:43You can see with COVID
- 48:44You can see
- 48:44It's called antigen presentation
- 48:46Is the name for this, by the way
- 48:47You're presenting an antigen from the virus
- 48:50And how the immune system can see it
- 48:52Opening up a little box
- 48:53And like a little briefcase
- 48:54And saying
- 48:54Here you go
- 48:55That's what this is
- 48:56Yeah
- 48:56That's what I'm saying
- 48:57And you're talking about the analogies
- 48:59And the more that I said
- 49:00I'll give you that
- 49:01It's interesting
- 49:02You mentioned Peter
- 49:03Peter Doherty
- 49:04Because his outfit
- 49:05The Doherty Institute is the main
- 49:08Is probably the most prestigious
- 49:10Institute in Australia now
- 49:11So all of the
- 49:12All Australians
- 49:12Maybe government was getting its COVID advice
- 49:14From the Doherty Institute in Australia
- 49:15It's very familiar with that name
- 49:17From getting a lot of
- 49:18Public Health advice
- 49:19During the pandemic
- 49:20And Josh
- 49:20From them
- 49:21Even better
- 49:22He's Irish, sure, man
- 49:23He's told me
- 49:24Anyway
- 49:25I think he's trying to answer
- 49:27Three of Actors of the y'all are saying
- 49:28Well, I suppose Doherty
- 49:29I suppose Doherty
- 49:30Yeah, you'll get away
- 49:31Give him away
- 49:32Um
- 49:33I've mentioned aspirin with regards to heart disease
- 49:35But I'd forgotten about aspirin's role
- 49:37Aspirin's role as an anti-inflammatory
- 49:39Uh
- 49:39Yeah
- 49:40As well
- 49:40Can you tell us the background
- 49:42To the development
- 49:43I can
- 49:44I can indeed
- 49:45I did my PhD in London
- 49:47In the place where that was
- 49:48Discovered actually before aspirin
- 49:50Was shown on how it works
- 49:51It was a mystery for a long time
- 49:53That goes back to herbal
- 49:54Stolf Josh
- 49:55It was first shown that will over
- 49:56Was anti-inflammatory you see
- 49:58And from the willow tree
- 50:00That said like a herbal thing
- 50:01Gone back hundreds of years
- 50:02Someone purifies from willow
- 50:04Things called salicylates
- 50:06From selic
- 50:06Switched the name of the willow
- 50:08And then salicylates
- 50:09Where were the basis for aspirin
- 50:10And it was made in the early 1900s
- 50:12As an anti-inflammatory
- 50:14Nobody knew how it worked
- 50:15Right
- 50:16Finally in the 70s
- 50:17They discovered
- 50:18Aspirin blocks things called prostaglandins
- 50:21Now prostaglandins are made by your immune system
- 50:24And they cause pain
- 50:25And swelling
- 50:25You know these prostaglandins
- 50:27Again, another chemical factor news
- 50:29An aspirin stops production of prostaglandins
- 50:31So hey, press though
- 50:32That was discovered
- 50:33And then on the back of that then
- 50:34Came drugs like ibuprofen
- 50:36Paracetamol
- 50:37They all do the same thing
- 50:38They all stop prostaglandins
- 50:39And that's why they're anti-inflammatory you see
- 50:41And they're useful
- 50:42In certain situations
- 50:44Why do they stop the disease
- 50:45Why do they stop pain
- 50:47Well prostaglandins
- 50:48Will sensitize nerve endings
- 50:50Pain is the part of the response to infection
- 50:53By the way
- 50:54If your damage is your hand
- 50:55And it gets injured say
- 50:57You want to guard it
- 50:58Don't you
- 50:58So pain is a normal response
- 51:01To protect that damage tissue
- 51:03So if you're using your hand
- 51:04So that's a repair
- 51:05You know
- 51:05But the trouble is
- 51:06It can go off guilt or again
- 51:07And the pain can be too intense
- 51:09And all the rest of it
- 51:10And prostaglandins are made in that injury
- 51:12Situation
- 51:13And then they're promoting that pain response
- 51:15And aspirin will stop that
- 51:16Is pain always a response to something real
- 51:18What about when I pop up ibuprofen
- 51:19Because I've got a headache
- 51:21Yeah
- 51:21Yeah, well again the headache
- 51:23Is being caused by prostaglandins
- 51:25Open your head now basically
- 51:26A causing vasodilation
- 51:28And enhancing the pain response there
- 51:30You see
- 51:30And that's actually a bad thing
- 51:31You know
- 51:32And that area of pain
- 51:34Is a very important area remember
- 51:35We need better pain killers
- 51:37That are addictive
- 51:38But that's a huge research area
- 51:40It took me almost
- 51:40Because pain is a feature of any diseases
- 51:42You know
- 51:42Now prostaglandins are causing what's called acute pain
- 51:45So just in response to injury
- 51:46You know
- 51:47There's more chronic pain
- 51:48And we need better ways
- 51:49To treat that in many ways
- 51:50So pain is a very important area of research
- 51:53I won't keep you forever Luke
- 51:55But let's just wrap up by thinking about
- 51:56How we can best make people scientifically literate
- 51:59Without resorting to education education education
- 52:02Because I know that you're in educator
- 52:03What's the look hanging fruit for people
- 52:05Who want
- 52:06Who are committed to the
- 52:08To the project of being reasonable
- 52:10And of following evidence
- 52:12To do so
- 52:13Are there cultural or communal
- 52:15Or I don't know
- 52:16Educational things that individuals can do
- 52:18Well as you said
- 52:20That likes to Carl Sagan
- 52:21And so on
- 52:21There's some fantastic popular science books out there
- 52:24I'd start with that
- 52:25Because they're so superb
- 52:26You written
- 52:27As you know
- 52:27It's brilliant
- 52:28There's a whole range of them in a way
- 52:30You know
- 52:31So reading
- 52:32These are the popular science books is great
- 52:34And obviously through TV
- 52:36And media
- 52:36And our conversation helps
- 52:37I hope
- 52:38You know
- 52:38Because
- 52:38Just just open your mind to science
- 52:40Is the trick here in a sense
- 52:41So find
- 52:42Find a writer
- 52:43Not more than in literature
- 52:44I'll bet the certain writers you hate
- 52:46You know
- 52:46If you might find a writer you like
- 52:47You know
- 52:49Whatever
- 52:50Float your vote
- 52:50You know
- 52:51Just just get stuck in
- 52:52Because
- 52:53Science is
- 52:54In my opinion anyway
- 52:56Science is one of the most
- 52:57Wonderful things we have
- 52:58As a species
- 52:58Because it's a way to explain the world
- 53:00Explain the world
- 53:01And then secondly maybe
- 53:02Get something useful
- 53:03That we need out of it
- 53:04And Covid is the great example of that
- 53:05You know
- 53:06Without science
- 53:07We've been a really bad place with Covid
- 53:09Like if Covid had cropped up
- 53:10A medieval times
- 53:11It would have killed millions
- 53:12You know
- 53:13And yeah
- 53:13We can have this stuff
- 53:14We can have this stuff
- 53:16And indeed it did
- 53:16But yeah
- 53:17But I'm talking about
- 53:18Not like that
- 53:19Yeah, hundreds of millions
- 53:20Hundreds of millions
- 53:21Forzaicely
- 53:22Yeah
- 53:22So
- 53:23So in other words
- 53:23Science, science
- 53:24To stop that
- 53:25And then
- 53:25She was a great reader
- 53:27While I'm knowledge
- 53:28I will add to the
- 53:29Reg to the general recommendation of books
- 53:31That Cosmos by Carl Sagan
- 53:33Is amazing
- 53:34And Dawkins' best book
- 53:35I think about this
- 53:37Sort of
- 53:37About the sort of
- 53:37Majesty of Sciences
- 53:39Is called Unweaving the Rainbow
- 53:41And Sagan's best book about
- 53:43Is the Demon Haunted World
- 53:44I think it's subtitled
- 53:45Science as a candle in the dark
- 53:47And it's
- 53:48Incredibly prescient
- 53:49When you read some of the passages
- 53:51From decades ago
- 53:52He's writing about
- 53:53A sort of scientifically
- 53:54Literate society
- 53:56That sort of dabbles
- 53:57In
- 53:57Witchcraft and Astrology
- 53:59And things like that
- 54:00And you know
- 54:00Gates their horoscopes
- 54:02And elects
- 54:04Sort of populist
- 54:07You know
- 54:07Celebrities as their leaders
- 54:09And doesn't really think
- 54:10Through things very rationally
- 54:11And you sort of
- 54:12Think about Trump
- 54:13And
- 54:14Johnson
- 54:14Still resonating
- 54:15Yeah, we haven't changed
- 54:17Watch out, we tap
- 54:18And judge over those
- 54:18Time-outs of yours
- 54:20Well, you're doing your bit, Luke
- 54:22So thanks for being with us
- 54:23And it's lovely to talk to you
- 54:24Take care
- 54:25Great, thanks very much
