News Items
Marijuana Safety (13:04)
S: Alright, let's go on to some news items. Jay, there's a new scientific report about the safety of marijuana.
J: In the United States guys, as you know, cannabis marijuana, weed, whatever you like to call it, it has been thought to be a very dangerous, and arguably became the most fought against drug, right? We had the whole reefer madness thing going on.
E: The war on drugs.
J: The war on drugs, exactly. Over the past 20 years though, a lot of opinion has changed, significantly in fact, to the point where a lot of states in the United States are now legalising marijuana and even releasing some people that are in prison that have certain levels of convictions, right?
B: Alaska recently legalised it.
E: Very recently, yeah.
J: A recent study tested how deadly are several common and popular drugs, and it did a side-by-side comparison with some very interesting results. The study was published in the journal Scientific Reports which is a subsidiary of Nature. Steve, I'm sure you've heard of that one.
S: Mmhmm.
J: The drugs they tested were cocaine, jack(?) tobacco, alcohol, cannabis, ecstasy, meth and heroin. Guys, take a guess, which drug was the most deadly? Evan, please start.
E: Well I start about that before I actually saw it and I would have guessed meth would have been probably near the top if not the top, but it turns out I'm wrong.
J: Bob?
B: Tobacco.
J: Steve?
S: No, I mean any physician knows alcohol's an extremely toxic drug, it wrecks people.
J: So in order of the most deadly, guys you guessed well. Alcohol, then heroin, then cocaine, Jack tobacco, ecstasy, meth and cannabis at the very end of the list. Now the amazing finding was that cannabis was far and away not even near the other drugs. In fact they found that cannabis is 114 times less deadly than alcohol. Now that's, I know that it just sounds like a number, but when you see the chart and alcohol is in the deadly slice which is all the way to the left, cannabis is all the way to the right, which is very profoundly not that deadly.
E: In those statistics, for example, is it considered for people behind, driving under the influence of alcohol dying in crashes versus people under the influence of marijuana dying in crashes, is that like a fair kind of comparison that's taken into consideration?
S: No.
J: I don't think they went there, no. I think they were just studying its biological effects.
E: OK so it's how it directly affects the human body.
B: Jay, so are you saying that cannabis is the gravity of drugs?
J: Yes, it is the weakest of the drugs tested, Bob, very good.
B: By far, very good Jay, you got that, you've been listening.
J: I've been listening to you in particular, and Bob, you're my hero.
B: (laughs)
J: You're somebody's hero. Steve, a few weeks ago you mentioned what was it, the DL50 test?
S: LD50.
J: The LD50 test, and they were using that methodology, or they were using that for the scale to see which drugs were the most deadly.
S: They also, they were using another measure too, not just the LD50. BMDL10 which is the dose which gives you a 10 percent increase in the risk of dying. The authors are careful to point out that the only thing they're comparing here is the relationship between the dose typically used and the dose that'll kill you.
J: Right.
S: That's what they're looking at, they're not looking at all of the effects of the drug, and even in the discussion, the authors say, this does not mean that regularly using heroin doesn't have horrible health effects. It just means that the typical dose that's used in relationship to the dose that's likely to be fatal. And that's where cannabis is very safe from that point of view because it doesn't cause a lot of acute toxicity, but that doesn't mean that, it doesn't say anything about the long-term effects of chronic exposure, they're not really looking at chronic exposure, just...
J: Right, which can have a lot of profound effects.
E: Liver failure.
J: Right, or cannabis could have emotional and psychological effects as well or whatever. So cannabis was the only drug out of the lot that had a low mortality risk. All the others had a relatively high or high mortality risk. Surprisingly, ecstasy and meth were the second and third least deadly. Keep in mind that they were very far away from cannabis but still they were a lot less deadly than alcohol and tobacco. Alcohol is so bad guys, it's more dangerous than heroin. It's really, really, really bad.
S: Well when you think about it, people drink toxic amounts of alcohol. When you're drunk, right? You're essentially...
E: Poisoned, technically.
S: If you think of alcohol as a drug, you're overdosing on alcohol deliberately in order to get the toxic effects so people actually push alcohol to toxicity as part of recreational use. Does that make sense? So it's actually not that far from there to dying of alcohol poisoning.
J: It's important to state guys, again like Steve said, this isn't an invitation to go buy a bag of weed and smoke yourself into Spicoli (?) Land. There's a growing mindset that since marijuana is natural, that it's safe. And the word natural is almost meaningless when we talk about safety. That would be like me saying that naturally occurring chemicals are safe or safer than non-naturally occurring chemicals, and that's bullshit.
Phantom Acupuncture (18:30)
S: OK let's move on. Have you guys heard of phantom acupuncture?
B: Yes, I have.
E: Is that a new play Andrew Lloyd Webber? That guy.
S: So, this is... I've heard of placebo acupuncture and sham acupuncture, now we have phantom acupuncture. So listen to this, this is what some researchers did.
E: OK, sounds redundant but alright.
S: Right? Well I think that was the point. You know that we can induce the experience of a phantom limb in a laboratory with pretty good reliability now.
B: Yeah, it's pretty cool.
E: It's remarkable.
S: The procedure is actually pretty simple. Let's say you're sitting in front of a table and one of your arms is on top of the table, the other one is under the table, and they're both sort of covered with a blanket and then there's a manikin or rubber arm on top of the table over your arm that's under the table. Right, you get that?
B: Yep.
S: So it looks like you have two arms on the table but one is rubber with your real arm being hidden under the table. And then, while you're looking at your arms, if somebody strokes the rubber arm in the same place and time that they stroke your real arm, you will feel and see the rubber arm being stroked. That's how your brain determines that you own the different parts of your body, right?
E: Steve, the brain overcomes the actual, I'm not sure what to call it, illusion that the rubber arm is made of rubber? It's able to sort of look past that?
S: The question has some assumptions in it that I think I need to address. Let me back up and just explain how the brain generates the sense of ownership in the first place. It's an active process and essentially what it's doing is comparing multiple different sensory streams at once: what you see, what you feel, what your motor planning is doing. Are the parts of your body doing what you want them to do? And then there are circuits that are comparing that information and they create the subjective sensation that we own the parts of our body and that we control the different parts of our body. There's actually a module in the brain called the ownership module that gives you the feedback that you own a part of your body. What happens in a phantom limb is that the ownership module still exists but even if you've had a limb amputated or it's dead, and so it's creating the sensation that you own this limb even if it's not there. And I know we've talked on the show about super-numinary phantom limbs where people have had, like after a stroke and part of their body is paralysed but their ownership module is still functioning, the ownership module may create a phantom limb because it's being deprived of the normal feed back that it gets, and so people have this hallucinatory limb, they think they have this extra arm that they feel like they own and can control.
J: Now Steve, also when someone loses a limb they could have phantom pain which is an odd phenomenon as well.
S: Right. One wrinkle to that is, like some people, their phantom sensation, like so they've had their arm amputated. They might feel like their fist is clenched and they're digging their fingernails into the palm of their hand and it's painful. One of the treatments for that is to put a mirror up so that they're looking at their intact limb but their brain sees it as their missing limb and then they open their hand so it's like visually signalling the brain that they're opening the phantom limb. And that often works. It takes the pain away.
B: Silly brain.
S: Yeah. So anyway, so now we'll get back to the acupuncture. If you do this with somebody and they successfully own the rubber hand, because of the tactile illusion, then they give acupuncture to the rubber arm. Right, so that's phantom acupuncture.
B: Wow.
S: What they found is that the brain...
E: The brain lights up.
S: The brain lights up in an fMRI scan, it responds in a way similar way to acupuncture of an actual limb.
J: Whoa.
E: Whaaaa...
S: When doing acupuncture of a phantom limb.
E: Oh my gosh, isn't that kind of a case closed kind of scenario. That's it?
S: Yeah.
B: Steve, are you saying that the rubber arms actually have meridians inside?
S: Yes, so obviously...
(laughter)
E: That's exactly what he's saying.
J: Yeah Bob, if you have a AAA battery in it, yes.
S: Yeah, it's beyond absurd to think that there's chi and meridians, life force, flowing through this rubber arm but it emphasises the fact that, how subjective these sensations are, and that even just visually tricking the brain is enough to get it to respond in a way that it thinks that it should be responding, it's sort of generating the expected experience even when nothing is actually physically happening, in this case, this is a pretty darn good control. The acupuncture is happening to a rubber arm so it can't be doing anything physiologically. The only real thing that's happening is that you're seeing it happen to an arm that your brain has been tricked into thinking is part of you. So yeah, isn't that fascinating? Now I always have to throw in the normal caveats here, this is one study, fMRI studies are really tricky to do, it would be interesting to see this replicated and to see how far we can take this but yeah, I found this very interesting. Now of course, some people will say, OK well acupuncture works by tricking the brain into thinking you're not having pain. So what? You're still not having pain. But that still gets you back to it's just an elaborate placebo, do you know what I mean? It doesn't mean you can treat cancer with acupuncture, that's always the problem I have is that they're using how easily our perception can be manipulated to say that there is something specific about acupuncture that has a specific effect and that the underlying philosophy is correct and all of that stuff and therefore I'm going to use it to treat high blood pressure and cancer and mumps and all of this other nonsense. But meanwhile studies show that just pain is incredibly distractable. You know, if you just look at the other arm while a procedure is being done on one of your arms, your perception of pain will be less, for example.
E: I do that when I get a shot in the arm, I turn away and concentrate on some other part of my body or something and I don't feel it.
S: Yeah exactly. Whereas if your attention were focussed on it it might be incredibly painful, but this pretty much undercuts the notion that therefore it must have a specific physiological effect or that chi is real or meridians are real, there's no support for that in any evidence.
E: So what's left? I mean the whole acupuncture paradigm falls entirely apart as far as I'm concerned.
J: Oh it won't do anything. Evan, nothing is going to change.
E: Oh I understand that, it's not going to convince the true believers, but that part of their argument is now entirely gone. It's over.
S: Yeah. So this wasn't looking at a clinical response, this was just looking at the brain response on an fMRI scan. The researchers said that they want to do follow up studies looking to see if there's a clinical response and that will be interesting as well. Other research already has shown that the only thing that really matters to the effect of acupuncture right, it doesn't matter where you stick the needles, it doesn't matter if you stick the needles, it doesn't matter if it's a trained acupuncturist or somebody who was just told ten minutes ago how to fake their way through it, none of that matters. The only thing that matters is the interaction between the acupuncturist and the patient. And the more supportive they are, the more positive they are, the better the outcome, and that's it. You could be randomly poking them with toothpicks but if you're nice and positive and confident they'll have a placebo effect. That's it.
E: What's next, virtual acupuncture in which you don't even have to touch the patient?
S: Well you don't, right? Therapeutic touch is virtual acupuncture, basically. Just waving your hands over somebody, literally there's nothing physical happening.
E: But they didn't call it something cool like virtual acupuncture.
S: There you go Evan, that's going to be your pseudoscience, you could do that, make a million bucks.
E: Alright! I'm getting the t-shirts made now.
S: Virtual acupuncture.
B: I'd go for multi-dimensional acupuncture.
S: Guys, quantum acupuncture.
B: Oh, there you go.
E: Oh, gosh.
J: That's good.
E: Wait, Deepak might already own the rights to that, we're going to have to check on that, yeah.
S: Yeah, that one's probably out there already.

- Answer to last week: Shepard's Tone
Dumbest Thing of the Week (41:00)
S: Alright well, we have another installer of the Dumbest Thing I Heard This Week which I guess is going to be the working title for a while.
J: Steve, can I bring up things that I hear at work?
S: It needs to be something in the public domain I think. It is remarkably easy to come up with bits for this segment, I mean it like writes itself. This week we have David Tredinnick who is a conservative member of parliament in the UK, and Tredinnick says he has the solution to the rising health care costs in the National Health Service in the UK, and that is: astrology.
(laughter)
E: Oh he's got quite a sense of humour, he's a regular Stephen Fry.
S: Yeah (laughs). He says, "I do believe that astrology and complementary medicine would help take the huge pressure off doctors."
E: Oh he's serious?
S: He's serious. He thinks that, "Astrology offers self-understanding to people. People who oppose what I say are usually bullies who have never studied astrology." So he's playing the you don't know the research card. He thinks astrology could be a diagnostic tool.
J: Really? OK, well what's his mechanism?
S: Jay, don't get in to mechanism, come on. What, are you crazy?
J: I'm just asking questions, Steve.
E: This guy is in parliament, and you're nothing. Don't...
S: Criticizes the BBC for being dismissive of astrology. Yah! Dismissive of nonsense.
E: That's right, he took down Professor Brian Cox too, for his dismissive approach, yeah.
S: Yeah, criticized Brian Cox, yeah.
E: Racially prejudiced?
S: Yeah, if you are opposed to astrology, you're racially prejudiced. Racially prejudiced, yes.
B: No, you're stupid prejudiced.
S: Tell us, tell us, Mr. Tredinnick, what's the race that promotes astrology or that culturally came up with astrology, tell us please, what race we're being prejudiced against when we say that astrology is complete and utter hokum?
E: I think he'll say, "the human race."
J: Yeah, I'm serious. I'm not sure he knows what the word really means, I think he thinks it means something else in that context.
S: Yeah, it's hard to know.
E: Guys, this guy won an election. I mean swaths of people turned out and pulled a lever for this guy.
S: So in any case...
B: His lever was certainly pulled.
S: Skeptics have looked at the data for astrology. First of all, it's, as Jay said, there's no possible mechanism. The idea that the apparent position of stars relative to each other or to the planets at the moment of your birth has some influence on you is pre-scientific superstition. Seriously, it's so old-school, like we don't even bother talking about it any more. I remember the first skeptics conference I went to they had a breakout session on astrology, there were three people in there. No one cares. You know what I mean? It's so played out, the idea that it's cropping up again at this level, a member of parliament. Astrology? Really? I mean that's just, that's embarrassing.
J: That's what you're going to tie your horse to? Like, that one? Alright, OK, here we go, break out the 50 year old literature.
S: (laughs) Right.
E: All praise Zeus I guess.
S: You haven't read the research... no, it's that we read it 50 years ago. So that's why David Tredinnick earns the Dumbest Thing I Heard This Week.
E: Well he earned it, the old fashioned way.
S: (laughs) I don't know how many people are going to get that Joke, Evan.
E: (laughs) It's a bit dated.
S: It is a bit dated.
Interview with Timothy Caulfield (46:13)
S: Joining us now is Timothy Caulfield, Tim, welcome to the Skeptics' Guide.
T: Hi There.
S: Tim, you're the author of two books, at least two books: Is Gwyneth Paltrow Wrong About Everything? When Celebrity Culture and Science Clash and your previous book The Cure for Everything, Untangling the Twisted Messages About Health, Fitness and Happiness. Are those your only two or do you have any other books?
T: I've got some boring legal ones that are probably less interesting. For the general public, those are the only two.
S: OK, great. Tell us a little bit about yourself.
T: I'm a health policy researcher here at the University of Alberta, and I like to think that we do very inter-disciplinary work looking at science policy, health policy issues ranging from really everything from stem cell research to obesity policy to complementary and alternative medicine, and what we really try to do is look at what the best evidence says about a given topic and then apply that to the policy issue, and that's what really brought me into the two books that you just mentioned, I've become increasingly interested, really over the last decade, in what the science says about particular health policy issues. And as you know there's often a massive disconnect so that's really what brought me into this.
S: Can I ask you, do you tend to take an evidence based approach or a science based approach?
T: You know what, that's a great question, it's something that I've been grappling with over the last couple of weeks, now I always think that I take a science based approach, but I've been accused of taking an evidence based approach because people love to draw on literature that talks about problems with evidence based medicine. But I really think of myself as a science based scholar.
S: Yeah. So you'll consider the plausibility of the treatments that you're evaluating.
T: Yeah, that's right, that's right.
S: So tell us, answer the question in the title of your book. So is Gwyneth Paltrow wrong about everything?
T: Look, she's... she's got great style and I think that she's a fine actress and when I was younger I think I may have even had a crush on her. But she's wrong about an awful lot and the reason that I... if you've read the book you'll know that I don't really pick on Gwyneth that much, I talk about a lot of other celebrities but I just think she's such a great example of the place of celebrities in our lives right now particularly in the context of science and health and how we think of the good life because not only does she talk about these things all the time, right? Whenever she gets the opportunity. She also, it's part of her brand, right? So it's part of how she markets herself to the universe so that's why I picked Gwyneth for the title and that's why I start the book with a little bit of some Gwyneth stories.
S: Yeah, so was the book in time to catch the whole steaming her vagina?
T: I know, no I missed the v-steam. But you know it was happening right when I was doing my book tour so I mean, thank you Gwyneth, I think I owe you a cheque or something. I mean you can't make that stuff up, right? The vagina steam. It's funny, I was talking about it in class earlier.
J: Hey, does she know about the book?
T: It's a great question, as you can imagine I get it all the time. I haven't heard from her yet, I reached out to her, I reach out to her on twitter all the time and of course I've tried to reach out to her people. When I was writing the book I got close to her, in the sense that I talked to many people that were close to her and they always said, oh Gwyneth would love this, I'm sure she'd love to talk to you and it never went anywhere. As you know the book hasn't been released in the U.S. yet so it'll be interesting to hear what happens when it comes out there. I'd love to talk with her, I always joke that I'd love to sit down and have a green tea with her and tell her about all the things that she gets wrong. (laughs)
S: How do you think she would respond, do you have any basis for an opinion on that, have you had a confrontation with any other celebrities about their nonsense?
T: I think that's a fascinating question, it's one I'd actually like to study believe it or not because I'm sure you guys think about this too: does she really believe the stuff that she's saying? And in fact I've always thought that if I had the chance to talk to Gwyneth, to interview her, I'd probably only get one or two questions. I'd probably be in a scrum. And the one question I was going to as was, Gwyneth, do you really believe the stuff that you say? Because I don't know, I don't know. I wonder that about other quacks, I wonder that about people who sell unproven stem cell therapies, I wonder that about homoeopaths. Do they really believe it? And I think there's probably a continuum out there and I suspect that Gwyneth falls on the side of the continuum where belief is real.
E: Yeah Tim, I agree with that, and here's my reasoning why. It's because this is not, primarily at least, what she does or what she's known for. She's an actress, she's a singer, she's this amazing super-star, people magazine every other week. She didn't really need to go ahead and do this and her whole Goop website which ties all these things together, it wasn't out of any sort of necessity so what other motivation would there be if she really didn't believe in these things?
T: Yeah you're absolutely right, and it's not like she has training in this and that it's part of her self-identification so she's got to stick with it, right? A personal philosophy. And also I note in the book, I don't really blame celebrities for their position because, look Gwyneth and all, particularly women, but really all celebrities are under incredible pressure to look good, to look young, and so I think they are victims probably more than anybody right? They've got to do whatever they can to stay youthful looking. So I wonder if that's part of the process that allows them to try a whole bunch of crazy things and then it's a slippery slope, they start telling the world about it and then before they know it they've got a clothing line and a cleanse product. So yeah I think that you're probably right.
S: Yeah and of course the audience here is not the celebrity, I mean I don't think there's a reasonable chance you're going to convert Gwyneth Paltrow to skepticism but we're trying to use her as a jumping off point to educate the public about the scientific process, health claims etc. But can we really have a significant impact compared to the power of celebrity?
T: You know, one of the things that I wanted to do with this book is, it's a little bit of a Trojan Horse, right? I know that there is this incredible fascination with celebrity and celebrity culture, in fact, you guys are probably aware of some of the speculation in scientific literature that we may be evolutionarily predisposed to follow celebrities and as Edward L Wilson talks about our love of gossip and of hearing about other people. So I think that's one of the reasons that I wanted to write the book, because I thought it was an excuse, a Trojan Horse to really bring in this discussion about science. Are we ever going to be able to combat the power of celebrity through skepticism and teaching science? I think probably not, but I do think, and one of the things that I recommend when I speak on this, I do think that the scientific community has to get more involved with popular culture and I think that (inaudible) and even over my career I've seen a massive difference, people used to look down on you if you were in popular culture, if you had a blog or if you tweeted. I don't think, I think that's changed. I think that people understand that scientists need to be a part of the discussion because if there isn't that voice out there it's just going to be Katy Perry and Gwyneth, right? So I don't think we can ever completely compete with it but I think we have to be part of the discussion.
S: Yeah I agree with you, I think that the scientific and academic community needs to be much more involved with popular culture than they are right now and while things have improved, academia is still a mixed bag in terms of how they view academics who engage with the popular culture. We're not there yet, let me put it that way.
T: I don't think we're there yet either. I think you're right. I mean people, they assume if you've read... it's the Carl Sagan effect right? The guy was doing great science his whole life and I think that his... you often hear how people viewed him differently as a result of the work that he did, and I think that's a shame. I think that you can do both and more people should. And the other thing that scientists should do and I think are doing increasingly is when they hear something inaccurate, speak up, right? And I think that is something tangible that can be done. I'm fortunate, I serve on a lot of scientific committees and that's a recommendation that often comes out, in the context of stem cells for example. When scientists hear something inaccurate stated about, you know, whether Gordie Howe getting a stem cell treatment, that they should speak up and get on the record about what the state of the science really is. And I think I'm seeing that more and more, do you agree?
S: I'm seeing everything more and more, just because of the internet.
(laughter)
S: We're still, I think, drowned out by orders of magnitude in terms of just the amount of information that's out there. Despite that we can have a hugely disproportionate impact. So how much are you involved with regulation of health care in Canada?
T: Well I have been involved in, (inaudible) I would say, in a variety of capacities have been very involved, I mentioned stem cells a couple of times, I've been involved in stem cell policy here quite a bit, in genetics, served on a variety of advisory committees. And so that's where, throughout my career I've seen people trying to integrate science into policy-making, and it's tough sometimes, because you've got to balance public desire, public perception, political issues, with what the science really says and sometimes the best response doesn't always emerge but at least you have to have science at the table.
S: Did you follow the cases of the, the two recent cases of the little girls, both native like six nation girls who had leukaemia and were going to a Florida clinic to receive traditional care and that became a court case over whether or not the state could require that they take chemotherapy?
T: Yes, I followed that quite closely and as a law professor it's a fascinating case and obviously I was very disappointed with the results and it's a wonderful example of how politics and law and cultural sensitivity can complicate, I'm trying to think of the right terms, choosing my terms carefully here, can really complicate a decision that would really hope would be driven by the best interests of the child and by science, and what's fascinating about that case, and I don't want to get too much into the law, is that there really was, there really is some complicating constitutional law that was used to justify that decision. I think everyone in my community is disappointed by the results and unfortunately now we have that precedent so it'll be interesting what happens when future cases emerge.
S: So was that really just up to the judge or, did they have discretion to go either way, or do you think the laws as they're written, this is the only way that the case could have gone?
T: So I think it was, I think it was wrong legally. I don't think that they interpreted the constitution the way that it could have been interpreted. Having said that, there was more nuance to the law than perhaps is often portrayed in the popular press describing the case. I think, where I think the judge got it wrong was claiming that this was a cultural practice that therefore exempted it from Canadian law. I don't think, I think the best interests of the child should have prevailed, which has in the past in Canada, in other cases. The classic example is the Jehovah's Witness cases, and there's cases in the US too that are like that. So I was, again, I was disappointed, particularly since, in this case, the science, the clinical evidence was so clear, right? It wasn't a situation where people were arguing to any great degree about the actual science, but it was really about the cultural practice. So again, a disappointing decision.
S: Yeah I agree, you're right, this is one of the most clear cases you can possibly have. Almost guaranteed, like 85% cure with standard therapy and almost guaranteed that she will die of her disease without standard therapy so there was no scientific, really, debate here. I also found it very interesting, and I don't know how much this came up in the case or the press in your neck of the woods, that the "traditional" healing that was being sought in both cases is some white guy in Florida peddling snake oil that has nothing to do with six nations traditional healing practices.
T: Yeah, for sure that came up, right? For sure that came up. And I found that infuriating, and I think, was it just today or yesterday that he had his license pulled? Or yeah, I don't know if I'd call it a license that was pulled.
S: He doesn't have a license. The state told him to stop practising medicine without a license.
T: Yeah exactly.
E: They gave him one so they could pull it.
(laughter)
T: There was nothing to pull. Yeah I found that really frustrating. But you know, that happens all the time, right? In complementary and alternative medicine, that homoeopathy is portrayed somehow as having this great cultural depth to it or something when it was invented (inaudible) right? And so I find that very frustrating and that was certainly the situation in this case. Just because it's an alternative practice does not mean that it necessarily has some great cultural history to it that exempts it from scientific scrutiny.
S: And of course, even if it were cultural, I think at the end of the day, society has a responsibility to a child, and they utterly failed both of those girls. One is now dead. The other one probably will be soon, which is unfortunate, that's the bottom line. No matter what you think the child is dead. So the story is over for her.
T: It is. It's just incredibly heartbreaking and one of the things that's so frustrating as a law professor is that we had this string of cases that I think clearly gave the court jurisdiction to step in, this was really about cultural practice and that's what it came down to, and I'm sure you've heard this, there was discussion amongst the media that people shouldn't be speaking so harshly of the native community in this regard, there really was, it was a vicious kind of debate and the end result was just tragic.
S: Alright well Tim do you have anything in the future that you're working on that you'd like us to talk about?
T: Well we are looking at things like supplements, we just finished an interesting paper on vitamin D which is another discussion we could have, that's like a religion and we were looking at how vitamin D was represented in the popular press as compared with what the actual scientific literature said on it. And we're looking at a couple of other things. The other thing that we're doing right now is looking at how science is represented on twitter. We're looking at it in the context of things like stem cells and we're using the Gordie Howe incident as an example. And the other thing that we have, we have a paper coming out in Science Translational Medicine next month where we look at claims about how soon stem cell research is going to get to the clinic and so, time to the clinic. And it's always 5 years in the future, right? That it's going to be in the clinic. So we think that's a really good example of science hype and how that can feed the science-sploitation phenomenon that I talked about. Because I do think that scientists take a little bit of the blame for some of the phenomenon that we're talking about in the context of science-sploitation because there's just been so much hype on that. So that's some of the work that we're doing right now and I've got a great interdisciplinary team, I like to believe that I just sit on peoples' coat tails and have fun.
S: Alright, Tim well it was great talking with you, thanks for being on the show.
T: A real pleasure guys, thanks so much for all the great work that you guys do.
S: Well, thank you.
J: Thanks, Tim.
E: Thanks, Tim.
