This Day in Skepticism (0:44)

• July 28, 1996: The remains of Kennewick Man was discovered

alright are Beck a porn about today yeah tell you what's important about today what you doing today is that this is the anniversary of July 28th anniversary the discovery of Kennewick Man 2396 Bieber means of man found in Washington State and people probably best snow can a man do to the controversy surrounding the ownership of the bones because of the local Native American tribe Matia questions custody other names and they wanted to bury them according to their tribal traditions and Sciences sued the US in order to have the ability to pass on the first and they won because the judge found that at the huge materia did not have a cultural tradition that connected in any way with the phones were suspected to be old and sure enough Winchester before they were found to be probably about nine thousand years old and because is Kennewick Man researchers figured out the deal about ah it's a complex issue because I don't know much about the spread of early American people we know a lot but there's a lot of time together man added a new puzzle piece it was quite interesting for a lot of researchers to figure out if there's been a lot of to be about what app where can we can came from and commands possible to send in square and all that good stuff so thats it thats the shortest I can I can some of that up for you the tailor to go with me to see a 2000 years old to be as much is 9000 Emilie interesting about that was at the school does not have a typical Native American teachers it looks like a tional oh it also has some other features that are doing question anything show this implies that the very different about the usual steno story that that has been sold population the American citizen new puzzle piece which really close to question a lot of thought we knew about who came over when that reason that your new modern Native American tribes to bring them to establish this is an ancestor they can't stop us a connection not even in American Sign terms of morphology DNA apparently has been a critical show show up to the ownership controversy in 2005 John McCain introduce amendment to neck pro which is the American grades protection repatriation exceeded the law that these Americans can say hey does bones your ass to inches you have to give me to watch the show the amendment would have said change the definition of Native American from: is indigenous to the United States to is or was indigenous to the United States but that fat to build is never passed this exchange had gone through man would be considered did American because you sound old take it and that would raise a whole new batch of issues because at that point to figure out which tribe get to bury Kennewick Man very good chance that you you won't be able to find a ride if you do a chance that people already wiped them out to the point that amendment was at all so many of the descendant have been wiped out really fair to require them to establish a continuous connection so they want to loosen the criteria but I think it's unfortunate because I'm a psychic point of view we want to study the remains of of human North America to pieces puzzle together and if you don't get the opportunity to do that we're going to lose a lot of information Ashley my opinion is that when you going back styles of years these bones belong to humanity their part of our shared history and your day any history of our species and yes I think that you have the right to have scientists study this to figure out to 50 piece of history together is a lot of religion Native American religion culture take it easy have certainly traditions if they believe that the scientist are investigating what are going against it really traditions then like that is there a position ray and was the argument and Avondale meteo is sad Daryl history goes back long enough to encompass tease at remains um and and governments nine that is the government rejecting the religious beliefs any right now this means are held at the Museum at you dub and they're not on display um because it would be insulting to this potentially in the Native Americans in controversy NCO when we should control over the years in limbo no actually this is owned by the federal government specifically the Army Corps of Engineers and being held by the museum is a neutral party but not being studied not being displayed so it really is still on result UTI I forgot to mention I mention to discover the remains at what makes the surnames particularly interesting is how completely where I'm at first blush it seem like they were only maybe a 100 200 years old um it wasn't until they did um radiocarbon dating that they were able to fix it The Day at around 9300 years so like the there only one maybe two major bones that were missing and Aries like fools set of teeth inside the school also is a tremendous amount that they could learn from these remains. What's the story from 9200 years ago in America.

Sally Ride (11:26)

CNN: Thank you, Sally Ride

so the news items we do have a sad news item this week Sally Ride passed away two days ago crushed her to see Sally Ride what was the first woman American in space she wrote a word the special challenger in 1983 on that made her a household name is you actually was a strong advocate a cation you usually use her fame to promote she had a website has the website Sally Ride science.com I produce education materials like that kik on sexy signs signs his life sciences physical signs to reach trying to supplement the very poor public school certification that we get in this country might feel so run science camp to clean girl only St Kitts for girls fourth grade she was awesome I was 13 years old when that happened with huge huge news and I was thinking to myself then why is she the first why we only having women in space this point it seem like it was such a long time coming can a link to the game directions sent to space 20 years prior 53.com is not really Tina Turner school but yeah 40 time direct to that party headlines for ride Sally Ride yes if it lucky growing up to it because she's such a household name by the time I was c*** isn't anything that had ever it never really occurred to me as a kid that will of course course women can go to Stacy be cool scientists I really look up to her you know but it didn't occur to me at the time that she was $60 and she initiate cross any boundaries and she agrees that frontier and she enjoy the faculty at the University of California San Diego the radical astrophysicist crap cleaner as hard core my main memory is for curly haired 0g yeah I was kinda curly show when I was was researching her I was looking up pictures everything I saw the pictures from her on the shuttle with her hair just like me to floating around everything that was burned into my head. Floating around everything that was burned into my head any out the interesting thing that came out after her desk is that not only is she the first woman American woman in space but she is also the first noon gay person in space she's very tight lipped about her private life tonight I don't think the people he knew that she was dying of pancreatic cancer and even fewer people knew that she had a long time lesbian partner 27 years together and her partner is also her business partner at Sally Ride science and she just didn't see the point in making a big deal out of it but there a lot of people now who are looking up to her as a gay icon to first and first lesbian in space Russian didn't know she was a lesbian until now so yeah I like the fact that I didn't know about it I just heard it right now and I really just don't care to be like its impact on when I think of her at all like it makes me even prouder of her because I mean she overcame so much. You know at the same time of the Boy Scouts of America controversy over discriminating against homosexuals. Hey it's really going against a living through a culture change you know a generational call to change for the younger generation of basically doesn't care about sexual orientation and you're just over time its it is attitudes are shifting the Boy Scouts now getting caught in the middle of it show me pictures of me about that is it a date discriminate against atheists and apparently that's OK but now they're getting slack for discriminating is too much sexual so I should mention Girl Scouts uh in in multiple countries initials happened in the US yet the Girl Scouts uh in their pledge Dame mention God and in several countries now Dave publicly dropped that in order to be more um galaxy read more appealing to be pretty girls and the Girl Scouts are awesome when it comes to science education and encouraging girls to explain the natural world so any cookies cookies what's not right in and tell me what's not to love how to change over the years eating those cookies guys so deadly girlscouts Kate noticed every decade you Jason stop it I got over that uses we've noticed that your cookie size is a freaking slowly and steadily beers FairPoint are you a teaser going out seriously make them bigger what are you doing like why stop a more just a record label in those condos cookies take more pictures did you guys hear about the Boy Scout who headed who had it was the Eagle Scout actually turned in the turned in his papers or what is is the bachelor fake give you bad idea the guy the guy wrote the board and said I can't in good conscience maintain my relationship with the Boy Scouts I see him a lot of fish add is back in protest of their sexuality those guys don't need no stinkin City

Mood Photography (17:36)

Neurologica Blog: Mood Photography

Alright well Jay, tell us about The latest in war photography if you guys ever hear of the line or a person's aura I have and what color are yours what do you think remind read pretty sure I'm purple orange here and I've always imagined your ass like a pill a crew Oh Steve actually like you don't have any and I explain to visible transparent well as many of you know you're there are people that believe that people give us or is that some people claim it taking actually see and the fact is that humans radiate electromagnetic energy but this is mostly infrared is it to function for body generating giving off sheet Pandora its just heat our bodies radiate energy in the form of radiation or light from our feelings or thoughts so you think about whatever you want to do whatever you want to kno wat it anyway to be able to attend today's technology see or read or peer into which actually going on in your mind and in your heart you said you sure there's no such thing isn't working right so yeah we use 89 cent called science to determine that Pandora doesn't exist so if you eat freezer please take a quick look at the electromagnetic spectrum where are the Sun where are the whores on that spectrum you by asking of course 2 answers you make it or what is metaphysical or is being picked up by somebody else it doesn't really criss cross with the physical world so people say does whatever to the typical huge spectrum of answers at you get what you ask these types of questions which is your blog today about people who have visual or sensory disorders in at an explanation for why they might see an aura DDS stand it exclamation the people believe it or see auras are just so polluted uh just suggest ability for three years in one way or another Veria speculations I will maybe they have synesthesia which we discussed actually a paper that pretty convinced we are you that doesn't sit well with the phenomenon show me to something else to: to smother visual disturbance they have a big deal to you have to visual illusion of a hella late 30 second do that 3:30 take a digitalis resampled see if you are too high does can make you see auras around any bright light source that's all very speculative and I don't think it's a major contributor to the phenomenon of people living in North Dakota mainly just new age belief and she just ability leaving or is mostly were influenced by the findings of a man named semen truly thought he was Russian better who is 39 accidentally discovered that object is on a photographic plate if its connected to voltage and images produced of that voltage stimulating a gas that image from special effects voice turns out I know you guys are dying to know the why are we talking about this today there's a new form a4a photography out there that's called the guy Coggins aura camera 6005 can you guess who invented the first eva is it guy c*** 6000 yeah 6300 cartoonish the Simpsons like right this guy and the orifice does that he takes it is, have a 10 second exposure and weather pictures being taken such a case is Santa the two boxes to capture biofeedback this device pics of electromagnetic fields that are measured at the higher vedik Meridian otherwise known as complete b******* points ugh I was reading about that it's really funny when you read a cup of the group that comes with explanations for things like this it take to reverse of energy that flows through your being an adult take a crap you'll read when you read about the air Vidic meridian translate this dataset came they came from the first place in our hands of these boxes into one or more colors its explain on the website through a patented operation distributors are projected as a radio or a field around the body language film along with the person different rates for sin to each color somebody you know about this radio oranges creative and artistic Greene Maine and healing and teaching a force of will blue file it is

Green Street main seal leak in teaching a force of will blue violet is beautiful I think it's more than enough to make anybody happy when you reach your own because everything is good don't say this particular color means you're young what color is skeptical J question do you have if you don't believe it or not I think it's there if I were to sign a colored to skepticism it would be sober okay so does the key here is that this is not taking a picture of anything this is just placing an artificial color on to the photographic film based on some BS interpretation of whatever the skin conductivity the bio feedback parameters isn't actually a picture of anything Raiders fake his shoes imaging is complete BS yes it's even stated some point I was reading that he said he knows that it's not really take me a picture of North simulating would look like guessing it was based upon tomato is a good thing is reading something very transy.edu skin conductivity temperature to fix properties can you change your body temperature in another city logical. This is this is about as Santa bring me a picture of yourself or around you and be safe thing to

Computer Modeling Life (24:06)

Phys.org: Researchers produce first complete computer model of an organism

Bob how was the first computer models pretty cool we are one step closer to treat Seaford researchers in the J Craig Center in student for the first time really tired music 20 computers to my life cycle Mycoplasma genitalium can anyone guess why they used a specific type of bacteria radio uh because because it has the smallest genome with any independent 2525 really really tiny e.coli for example which is probably a comp it has 4288 guys really really tiny Nissan to know your day with the word 2 2009 to synthesize remember that you use it because it was really tiny and go to be easy to do this is a parasitic bacterium that is usually on wanted to shows up in human respiratory and your genital tract is a transmitter a sexually transmitted to see so a really I want guys on you but done but why would we even want to respect your me to software does she like to read a primarily it's all about bringing amount of data under 18 years now when the biggest problem has not been getting enough to actually using a high-throughput studies have now you can create library really really fast problem now is trying to understand the passage reductionist approach me with Gene and knock it out and see what she says 13 minutes nothing to get a big picture of what's going on at Stanford engineering team lead Marcus Cooper Ted many of the issues were interested in aren't single gene problems into the complex result of hundreds or thousands of jeans interacting with us off the team use your own instrument and data from more than 900 scientific papers about this organism in detail things like I'm too old by logical molecular directions note to take place inside the cell phone from birth to death to keep Vancity me that I would say what's the status and then make all the stator work together in to do this by 28 different modules are categories of molecules and interactions within the cell who sings like DNA and rRNA Andy and molecules I can have a light at Dr Jenner it within the cells during the tablet and it is much wasn't communicated with each other during each time step program when was run to turn the super discreet elements into a single unified did you were going to a key factor I think it's really critical and really fascinating validated this computer model I was able to reproduce independent map data that examined many different cell phone many different scales create a model in matches with reality you're definitely at least you're on your this pretty accurate so if you're traveling this to a person that to you know that's what a tremendous oh my god oh yeah I know that's not get silly to my usual question is will want me to future hold for this kind of technology II think I see a fleet fleet design to cure a yeast mass producing sick from Brainerd possibility for the lapse in 2008 I much faster than you can imagine doing right now on this could give the ability to you suck at a computer aided design in medicine and bioengineering never really be done before

Artificial Jellyfish (28:30)

BBC News: Artificial jellyfish created from heart cells

a different kind of artificial organs inside created yeah I'm going to type you bump okay no not really haha yeah that's it take to get this is interesting Kevin kit Parker is a professor of bioengineering and physics at Harvard he was interested in growing a hearts how does one grow heart and use inspired by the way that jellyfish pump a muscle in order to lose water so you decided to try to create an artificial jellyfish you seen heartfelt really hurt cells from Iraq so long with researchers at those Harvard and Kel Tec uh He spent years studying how chilly fish move before they're able to create jellyfish like silicone body under which the printed this pattern of proteins that mimic the musculature of jellyfish next eclipse of the heart muscle is the heart muscle cells over the body and then they dropped it into a container of electrically conducting fluid and then shut it which forced to cells to contract and lose this synthetic jellyfish around water show the basic Lee Dave bioengineered a jellyfish ah I need to plan it when I found out that it was being held this year and you know it as it is playing the can actually reproduce and can't move on its own so apparently the sales contract slightly before the electricity was applied which is I don't think she is amazing to me is that this team isn't sending out a perfectly recreate a jellyfish instead the identified the primary function of a jellyfish and they talk about a new way to create it no there jellyfish doesn't look exactly like a jellyfish it is designed to move to the water though at in the way a jellyfish does um but better basically Atticus evolution is this message process and it doesn't always result in the perfect tool for the job I applied to the idea of creating replacement parts for people maybe we don't necessarily need to recreate the human heart this weekend instead building new more streamlined Oregon that's better suited for the job and it seems to be dis teams goal lead author jenna doll Ross said that to shoot engineers currently try to copy to show Oregon based on what they think is important or with AC is the major components without necessarily understanding of this component a relevant the desired function without analyzing first how different materials can be used to as for the jellyfish there now working on a simple green for it so that I can respond to it by tonight or seeking out food or energy however I could find no plans currently play status capabilities point here before we get emailed about it that the term jellyfishes out of favor because of jelly fish yeah it's not official but dumb a lot of clear easytether have been using the term jelly receive jelly rather than jellyfish butter jelly fish is still I think an acceptable terms are finish obviously yeah right right Jenny's starfish in agriculture starfish anymore see stars in India does saying anything the fish in the water in general accurate rifle mammals that live in the water to whatever let me know they were going to change the names of catfish is not really cats fish no its not even if you need a maid band man my country trip transgender what spongebob oh sorry I'm not 12 The Show yes he did you do that mermaid man died the character are the actors in the movie 3900 yeah how soon to be a dragon to use for a switch

Firewalk Mishap (33:20)

Neurologica Blog: Firewalk Mishap

Alright Evan, finish up the news items for us with Find interesting firewalking mishap that happen a reason firewalking this is Grace still doing this Tony Robbins you know self help guru on TVs big screen to other folks in headlights last week in San Jose I need inspiration talked into trees and shout the victory fire water attended by thousands I can DNA streaks off from phone scorched by the superhero with this is not know that for sure the 21 people were treated for burn injuries after going through the a fire walk exercise by which Tony and others claim that its use mind over matter you too can walk over fiery hot coals burn up at temperatures of to 2000 degrees Fahrenheit how is that possible what channel trick is what is what it is and STD did a good job you were leaving the difference between the. Of fate would vs metal on the difference between thermal conductance uh vs thermal capacity big big difference yeah I used tires as an example of a very high thermal conductance and capacity to transfer a lot of energy to learn to see if you touched a piece of iron a 2000 degrees it would a cookie very quickly as opposed to would guess very low thermal conductor for transfers energy very slowly she could touch it for 1500 restuarant hider so but not much is a huge gets transferred to your feet walking walking to go to leak brisk pace and also a short distance Richard Wiseman 2 years ago pm9 xillvideo about people were doing the fire walk with the fire walk with too long as I know the usual 10 to 15 to 25 to 30 for sure we get to about the halfway point in 15-20 feet that's it you have to keep at it wasn't just that the fire what happened to be too long is that Richard purposely made it too long where is the fireworks yeah its purest physics esse amount if he can hold how quickly can transfer it on and that's it and there was some discussion DVD ash translation I guess that is probably a minor player ameature STDs I'm shocked at that guys cheat didn't buy the power of their own will help those people walking to close your eyes grow um yeah people bringing a lot and that's a fact basically people have dairy PPV sweatier moist and I believe that that will let you create a barrier I very very very minor player and I wouldn't trust it just a fact you wanted to see a hot scale on the on the burner in your kitchen and your water on a little bit of water it's kind of scary around and it cut it last a long long time you think it should where can I bury underneath a water droplet back taxes insulation to transfer of heat to Tia to wear the droplet it away and I might be a reminder player in this really was the thermal capacity in any conduct do that that if your feet are sweaty that the members me to stick to your feet is a contact in this really pretty and has nothing to do with thinking about 30 firewalking Institute research and education organization to firt fire how long does it take to get to three weeks get this its a world-class Institute at international certifies firewalk instructors to the highest standard of safety to their press release because they had something something say about this they said and I quote sanity I think until the 21 out of 6000 who took part equates 2286 likelihood of receiving a second or third degree burn at this event what happened they say the lifetime risk of death from riding in a car is 184 a custom that is seldom given second thought uh hello apple orange uh how to walk across guns to get to school for grocery store hahaha yo city was reading this article that there's gotta be somebody take a tire to do these events like you just put on fire walk event if you don't know what you're doing in the next person that knows what they're doing has to know what the physics are right after a bit idea of like how long should be at what stage during the fire you how happy birthday to the embers have to be in order for someone to walk on it right 30 different definitely physics behind it just makes me think a lot of people that accept these things up actually do know these are the parameters at have to be met in order for people not to burn them so sure to get to stick to get people think that would ever the psychological easy answer that beer paneling is say something you know yeah but then you know the exit Dead TV show that you mentioned earlier that Richard Wiseman to sit in demonstrates clearly that there are plenty of people running these things who are true believers because she took people run fireworks and he extended leave them they were positive they could still do it nothing just needed to meditate a bit more and they make a cross and that's what makes a video funny is it a try it you know they start walking across a very calm and serene and then Midway they just suddenly run and jump into this clearly thought that this is going to work on it wouldn't have done it on camera so I I suspect there's a lot of people who turn it in terms of coke this is a standard playing this is how long do you wait before sending people cross you know and it didn't really think that the user hard and fast rules for reason I think they just think that's just how it's done.

Who's That Noisy? (40:30)

Alright well Evan, you're also going to get us up to date on Who's That Noisy we're a couple of weeks behind I think. 30 a couple weeks behind yeah couple weeks behind uh so absurd 364 field answer to that and we need to announce to accrue guessed correctly for a rose out of practice on that one good job everyone for recognizing that Victor Sam and uh John about the name of tree in OC was the first correct tren o si Racha lations to that is and then the last time when we left you last had a a local to play last week and let you know who if anyone so here we go s*** you guys remember that yeah yeah yeah yeah what is several guess is well talk to people who do I track from the message boards uh show sucked yesterday baby sloth right track there mobloc guess a baby crocodile tractor but neither of those kisses were correct this was a baby 12 to be here it's amazing what you think when you type in a weird noises babies make you get on first comes up as a human being take you but just making a weird noise very healthy one just making a weird noise kind of green yeah a little bit of an Girling cracked yeah its sick so they were the closest but not quite right so uh I'll take a picture on a already what are you up to this week alright after rereading supposing of the month okay guys of this one too short it's a little bit little bit difficult to hear I think the audience is going to play this back a couple times but I also predict that you will be at least one correct guessing this week att.net call you get that's all you need to find out find out next week that's right now it's got da torque in SU forrent.com does a way to get ahold of give us your guess good luck to everybody.

Questions and Emails

Multivitamins (43:26)

Show me to do one email this week this one comes from Chris to write you guys a great job convincing me that vitamin megadosing is a waste what about a multivitamin clearly it would be best if I eat a healthy diet I should I workout everyday give to charity volunteer learn to play music the real question is what's better a s***** diet with no vitamins or s***** diet with a multivitamin to show sex what do you guys think about that interesting version of this question we do get this the last goodbye to me all the time idea to visit you know he's just between the information to the public in the actual signs to say this but I remember when you talk about vitamin is that uses supplement for certain deficiencies for people who have certain conditions in which there they cannot or do not get certain vitamins and therefore yes they do need a compliment but that's only to be sore did you know done with you if I see a doctor is part of you know regiment um II think just taking a multivitamin for the sake taking multivitamin probably doesn't do much for a week is normal diary to get all the new series what if you don't have a healthy diet a crappy diet I think it would have to be prepare a crappy a reverse more than your average height a warrant to warrant a multivitamin more than you would think yes I guess it depends is the short answer on what you're saying but it just having a dent on healthy diet near a guiter you too much red meat and vegetables whatever d everything shows you cannot make up for that you can't have a crappy diet and take a multivitamin anyway come to your crappy diet you're not benefits a lot of benefits of having to Trish's diet.com from having a meeting like gifts for free to vegetables and then not eating the stuff that you should be eating like you too much fatter too much red meat or whatever that point of view the answer is no vitamins do not compensate for a bad diet because part of what makes a diet healthy is that you getting to much of sur stuff you're not getting enough nutrients however if your diet is a bad or is just restrictive in a certain way that you actually will become deficient in vitamin supplement doing to prevent that deficiency will help treat at deficiency that should be targeted to whatever your decision is the most common ones I see are actually. If you give you don't know how to have a proper vegetarian diet it's very common for people become b12 deficient you and I do you know if you know what you're doing but if you decide not really reading about doing what you're doing to me from your diet in a couple years down the road there b12 deficient ODST need and b12 supplements basically told Ricky Dillard actually a case is like that of course is like a specific conditions where is helpful apps fully for pregnant women for example is a common even if you're not to fish in taking a leak does heat reduce the incidence of neural tube defects but you have to be taken before you know your pregnant if I tell me no happened so short answer is a bad diet but if its not restrictive bed with your decision then yes obviously will fix the deficiency a good diet there's no benefits to taking a multivitamin.

Voiceover: It's time for Science or Fiction

S: Each week I come up with three science news items or facts, two real and one fake. And I challenge my panel of skeptics to tell me which one they think is the fake. You guys ready for this week?

J: Yeah.

B: Yeah.

E: Uh huh.

J: Oh Yeah.

S: Oh yeah. Okay, here we go. Item number one: A new study show that while multitasking a visual task with an audio task—such as driving while talking on the phone—significantly impairs performance, combining two visual tasks had little effect. Item number two: Scientists have identified a new syndrome—delayed severe allergic reaction to red meat caused by a tick bite. And item number three: Researchers have found a distinct subsystem for smell in the mouse that is likely dedicated to smelling behaviorally important odors, such as fear. Bob, go first.

B: Uh, oh boy, wow. You know you read news items— I don't know where you pull these from. Ummm.

S: And you never will (laughs), if I can help it! Imagine how hard my job would be if you knew where I'm going for my stupid news items.

B: Ha, ha. Alright a new study shows that while multitasking a visual test with an audio task impairs performance like we've heard before, but combing two visuals had little effect. Uh man, you know, I'm just not, I'm just not buying that. Cause all the studies I've read, not recently, but we've talked about it enough, they really didn't distinguish that. And I would think that, I would think that if you had two visual tasks, I mean, the idea of going back and forth, you know, would kind of the same as, you know, multitasking at work. You're going from one task to another, to the other and it's just never as good as just sticking to the one for a while. Umm, hmm. Let's see. Got a new syndrome here, delayed severe allergic reaction to red meat caused by a tick bite. Damn. I have no idea what to say about that. I can't think of anything that would get any red flags. Oh geez, I don't know. Let's see what the third one is. Distinct subsystem for smell in the mouse dedicated to things like fear. Umm, bsch-yeah, I guess, that's possible. When a creature is experiencing fear there could be some sort of release of something that would be identifiable and associated with fear— I guess. Two visual tasks. Alright, I'm gonna say the multitasking one. Umm, I'm— I still think that even if it's two visual tasks that multitasking there will be some impairment going on, because that. So yeah, I'll say that ones fiction.

S: Okay, and Rebecca?

R: Okay, the multitasking item reminds me of something I read ages ago that showed that talking on a cell phone while driving impairs your ability to drive safely much, much than carrying on a conversation with someone who is in the car with you. Which at the time, I think, was attributed to the fact that you don't have to guess at the other person's emotions and things when they're in the car with you. But you are using your sight. Uhh, so, more so, than you would on the cell phone. So, because of that, that item rings true to me. That, uhh, audio is more demanding for us than visuals. Sooo, tentatively I'm saying that one makes sense. "Allergic reaction to red meat caused by a tick bite", I haven't, I only recently learned that you can have allergic reactions to meat. I didn't realize that was a thing. But I know that is a thing now so I'm more likely to believe that than I might have previously. Caused by a tick bite? Yeah, I mean, I guess see, maybe, you know you have a certain immune response to a tick bite that also cause an allergy that you didn't have before. So that one makes sense too. The one, the one that's not making sense is the idea that mice have a dedicated area for, a dedicated subsystem for smelling fear because, mostly because behaviorally important odors such as fear, that's what bugs me because I don't understand how smelling fear in another animal is important to mouse at all. Like mice are just scared of everything, all the time. Right? Like why would they care if the cat that's after them is afraid of something. Suddenly they are gonna turn around and charge the cat? No, that's not gonna happen. I've never seen that happen. All I've ever seen is mice running for their dear little lives. So, I can't see any reason for the mouse to have the ability to detect fear in other animals. So, that one, I'm gonna say is the fiction.

S: Okay, Evan?

E: Well, let's have a look. Umm, the multitasking one, we've spoken quite a few times on the show about multitasking. Umm, but specifically, visual task with an audio task? I'm not sure we've phrased it in a specific context such as this. So, umm, it's very interesting. Significantly impairs performance, combining two visual effects had little effect. Two visual tasks had little effect. Well, driving is a visual task, what else would I be doing while I'm driving? Visual task, well— texting is a visual task. Kinda thinking that, I mean, well that's other tasks as well but certainly visuals a main component of that. Uhh, hhm, I'm not sure about that one. Umm, the second one the new syndrome. Severe— delayed severe allergic reaction to red meat. And the tick bites the carrier? So apparently what's happening here is that the tick bite carries something in it's saliva? Little tick's saliva? That gets into your system, through the blood and causes you to have an allergic reaction to red meat? Is the anything— I can't—I'm trying to think of what else to kinda equate this to. But I can't think of an example off the top of my head. (sucks breath) So, moving one to the last one. Mi— I mean— uhh. Mice that have a distinct subsystem for smell? That smells behavioral[ly] important odors as fear. I'm thinking that that one's— of the three— I kinda think that that one probably is the most likely to be true. You know, they find all kinds of cool things about mice. Mice are the classic test animal. But a distinct subsystem. Uhh, I'm not sure, that one seems to make a lot of sense to me in a certain way. Umm, Rebecca, you were talking about how mice are kinda fearful and skittish of everything and I think that actually plays into, uhh, why they may have a subsystem for it that they detect it. So, it's between, for me, multitasking or the tick bite and allergy. (sucks breath) Uhh, well, I don't like the two visual tasks having little effect. I don't know about that, I think you really gotta keep your eyes on the road, that's the bottom line. So, I'll say that that one's the fiction.

J: That a boy!

S: (drowsily) I'm sorry, which one?

E: The multitasking is the fiction.

S: I'm, I was doing something else.

(laughter)

S: Alright, Jay?

E: Ha, ha, ha.

J: I'm gonna go in reverse order. I absolutely think the one about the mice smelling fear— being wired to smell fear. Sure, that makes a lot of sense to me. I'm curious to know—

R: Seriously?

J: Yeah, just.

R: Just me?

J: Well, you know, I don't want to throw out the big pheromone thing. I mean it's like people throw that word around like, you know, it explains all these different things or whatever. But absolutely, you know, sure they could smell— you know, you were talking about the cat as a predator and all that and, sure, why wouldn't they be able to smell it. Smell things that the animal is putting off, whatever. Yeah, that makes sense. The one about the red meat caused by tick bites, the allergy situation. The only thing about that one I don't like is the word "delayed". Like a "delayed sever allergic reaction". Why would it be delayed? It's very strange. I hate ticks and I hate being bitten by ticks and I hate everything to do with them. And I think we should try to destroy all ticks and bedbugs. But anyway, I don't know about this one, I mean, what have I got to say other than it's weird and I hope that that one's the fiction. But the one that I didn't like from the moment that I heard it— that's why I went in reverse order— is this whole hoo-hah about combing visual tasks has little effect, that's BS. Combining visual tasks, meaning two different things you have to visually keep track of at the same time, that one is the fiction by far. Is the fiction. Thank-you.

S: Okay.

J: Thank-you.

S: Alright. So—

R: I'm alone in here? I can't believe I'm the only—like, uh!

S: (dryly) You're alone.

J: A-looone!

R: Immediately the mouse one.

S: You're alone. Jay, what about bed ticks? What do you feel about them?

J: Oh my God. Imagine if there were pen ticks! (laughs) Oh my God. No!

R: Dear Lord, no. Something new to be scared of.

E:

S: Alright. You all agree that scientists have identified a new syndrome, a delayed sever allergic reaction to red meat caused by a tick bite. You all think that one is science. And that one is (pauses)— science.

J: Uh, why is it delayed?

R: Yay!

J: Why delayed?

S: I don't know. But it's the first one. It's the first delayed anaphylactic, or severe allergic, reaction that has been identified.

E: Wow.

S: Uh, this is a study, really a case series, where they identified two patients that the same syndrome. They were all bitten by the lone star tick and had a—

R: How ironic, given the Lone Star Steakhouse.

S: Yeah. So the—

E: Ha, ha, ha. Sorry. I like that.

S: The tick has a specific carbohydrate that produces an immune response. The same carbohydrate is in the red meat, meat derived from mammals, so can produce a secondary or an anaphylactic severe allergic reaction. There are a couple of firsts here. This is the first identified anaphylactic reaction to a non-protein, to a carbohydrate. It's the first delayed reaction, 6-8 hours delayed after eating the meat. So, like you have a steak dinner and then in the middle of the night you wake up and can't breathe.

J: Yikes.

S: Yeah.

J: Ticks really suck.

S: Triggered by a tick bite! Yeah, that's cool. It's very interesting.

J: I mean, seriously—

S: Imagine how hard it is to make that diagnosis. But they're saying that if there are physicians in this part of the world, bits of the south-west, and patients present with an anaphylactic reaction after consuming red meat you should consider this newly identified syndrome. Very interesting. There are a lot of new things in there. Umm, let's go back to number 1: A new study shows that while multitasking a visual task with an audio task, such as driving while talking on the phone, significantly impairs performance, combining two visual tasks had little effect. Bob, Jay and Evan, you all think this one is the fiction.

S: And Rebecca—

E: (resignedly) Uhh.

S: (continues) You think this one is science.

R: No whammy, no whammy, no whammy.

E: This is it.

S: This one is—

E: I mean, this is it, right?

J: Oh—

S: (continues) The fiction!

E, B, J: (collective joyous moaning)

S: It was fiction! I suppose you could have thought that maybe, like, if you were integrating two visual into one, sort of, meta-visual task that wouldn't be multitasking but— no, no. Uhh, but no. It did in fact— the study showed that combining two visual tasks is even worse. Has more of a negative effect

S: (continues) That was the way to go with this one.

J: Thank you.

R: Ewwwh.

B: C'mon, it was obvious.

E: Wow. (cat noise)

S: They used eye tracking technology to see how the subjects were handling the tasks that they were given but also their performance on the task. And, yeah, when trying to combine two visual tasks their performance greatly suffered. The other interesting wrinkle here though is that when asked how they did, the people who were trying to multitask two visual tasks thought that they did better than when trying to multitask a visual and an audio task, even though they did worse. So they had a false sense of security, if you will, with the two visual tasks. So they were trying to model what would be worse, talking on the cell phone while driving or texting while driving. And definitely, texting while driving is much worse.

J: That's odd.

S: Kind of seems intuitive to me. I mean, you are visually distracted while trying to text.

R: Yeah, but, and you're using your fingers.

S: Yeah, although I don't—

S: I don't think that's the component though, the problem.

R: Really?

S: It's just the distraction. The diminishing of attention. You have to look away from the road to text. You brought up the previous data that shows that it's more distracting to talk on the phone than to someone who's sitting next to you in the car. We've brought this up before, you know, there's speculation about why that might be. There's the extra set of eyes, (do they) compensate for the distraction somewhat? My personal experience is that I find it really hard to talk on a cell phone, in that is takes a certain amount of concentration because the cell phone companies typically give just enough bandwidth so that human speech is recognizable. But not a lot more than that. So they are always restraining the bandwidth and I just find the audio quality, even as phones get better, the audio quality is really such that I really have to pay attention to understand what the person is saying over the cell phone.

R: Yeah.

S: Do you guys find that too?

J: No!

R: Yeah, I guess. I don't drive.

J: Ahhhh!

E: Yeah, that's right.

J: No, I don't agree with you.

S: And now we've got to use the the hands-free devices and some crappy ear phone, you're not even holding the phone up to your head. It's even harder.

J: What do you mean, it's harder?

E: It's harder. The voice, the sound quality is worse with the hands-free ear buds.

J: My head phones are epic. I have Bose headphones

Item number 1: A new study shows that while multitasking a visual task with an audio task, such as driving while talking on the phone, significantly impairs performance, combining two visual tasks had little effect. Item number 2: Scientists have identified a new syndrome - delayed severe allergic reaction to red meat caused by a tick bite. Item number 3: Researchers have found a distinct subsytem for smell in the mouse that is likely dedicated to smelling behaviorally important odors, such as fear.
