The Show
This Week in Science (TWIS) is a weekly, hour-long web and radio show presenting an humorous, often opinionated, and irreverent look at the week in science and technology. In each episode, TWIS discusses the latest in cutting-edge science news on topics such as genetic engineering, stem cells, cybernetics, epigenetics, space exploration, neuroscience, microbiology, the end of the world, and a show favorite – Countdown to World Robot Domination.
TWIS broadcasts weekly at 7:30pm Pacific Time on Thursdays in live streaming video from the This Week in Tech Network, TWiT.TV. TWIS audio is rebroadcast from KDVS, 90.3 FM in Davis, CA on Tuesdays at 8:30am PT.

The Hosts
Dr. Kiki (Kirsten Sanford, PhD)
Before coming to Earth, Kirsten was stuck in a dead-end job as a space medic in charge of routine bloodwork in a M*A*S*H unit during the Clone Wars. With most of her hours spent doing midi-chlorian counts of sick and injured Jedi, the work quickly became boring for an active scientific mind like Kirsten’s. Nothing is more annoying than a Knight of the Force who can’t stop whining, and hearing nothing but that day in and day out, she just up and quit one day after reading a want-ad put out by the ICCX looking for scientists to be sent to Earth. Once on the job, Kirsten skillfully nosedived her AstroPod deep in some thick jungles near the planet’s equator. She named the region Burma, in memory of her beloved pet space monkey that she was forced to leave behind on her homeworld. Initially mistaking elephants for the dominant sentient species of Earth, Kirsten spent several hundred years before realizing that it was humans she was meant to study. Once that minor error was rectified, however, she wasted little time and soon was hired as chief brain surgeon to the King of Siam, under whose patronage she was able to catalog the entire extant taxonomy of Southeast Asia’s bacterial phyla (a great many centuries later, the events of this period in Kirsten’s earthly tenure would inspire the musical “The King and I” starring Yul Brynner). In time, her scientific research led her to roam the world. She walked the steppes of ancient Russia, inadvertently inventing Tartar sauce, and at length arrived in Europe toward the end of the Dark Ages. Here she documented flora and fauna, instructed local healers on the use of vitamin C in treating the Black Death, and compiled many handwritten herbals, parchment documents penned in her flowery native alien script. Some of these can still be found in rare bookshops today; the inscrutable “Voynich Manuscript” is an example of Kirsten’s early biological fieldwork on this planet. Kirsten helped bring the life sciences into the modern age when, in the mid-19th Century, she took work as a pest controller in the pea garden of an Augustinian monastery in Moravia. Here she helped a monk named Gregor Mendel develop his theories of trait heredity that would eventually grow into the science of genetics. Using her special powers, Kirsten then was able to command a flock of African swallows to carry her to the Americas, setting her down in California’s fertile central valley. Pursuing her work with birds, Kirsten enrolled in a major human research institution and studied the effects of hormones on memory formation in zebra finches. During a hiatus from school, she found work in a prominent San Francisco research hospital working on scientific experiments in which willing human test subjects were given large doses of recreational drugs. Kirsten returned to school to finish her doctorate program in Neurophysiology, enjoying a special brand of masochism by choosing do both her undergrad as well as graduate work at the University of California at Davis. Apparently she loves the smell of cow poop in the morning. It smells like victory.

Justin Jackson
An anarchistic utilitarian mystic by birth, he converted to extroverted existentialism around the age of four. By age seven he had founded “The Institute of Reason”, a common sense think tank of like minded seven year olds working to improve the world they had inherited, over which he presided as Director until an unfortunate oversight in the bylaws of the institute forced him to resign on the eve of his eighth birthday. On the walls of Justin’s office hang several PHD diplomas from top U.S. universities, including (Yale, Harvard, Stanford and UC Davis). None of them bare his name, a fact that, when confronted with, is defended by him countering “Want a drink?.” Or the possibly more sinister… “They’re just trophies. (followed by a maniacal laugh)” A self-described delusional and gift to all womankind, Justin has little tolerance for the delusional behavior of others, as is evident in his ongoing attempts to lobby members of congress to have himself installed as the nations first Religion Czar. When first approached by Kirsten to be a minion co-host of TWIS, he believed her to be a figment of his imagination, and so agreed to do the show. Feeling the stings of Kirsten’s wrath after not showing up to the first show, he began to take his imagination more seriously.
Favorite Scientist: Nikola Tesla
Vision: excellent at 20/10

Who does the music for the show? I’ve been trying to find it all morning.
Hi Kirsten and Justin, I just thought I should bring this new TWiS to your attention; Surely they could think of another title…?!?

We are still on. I don’t know why Stitcher would no longer carry our podcast. Thanks for the note!
TWIS!
I’m not a big deal, but I wanted to let you know that I have included your podcast in my top 10 podcasts of 2011. I really enjoy your podcast, and if I was more of a scientific person, you probably would have been a higher number. My website used to be bigger, but the server crashed and I am just now recovering. The list is at http://www.davidj.org/top.ten.podcasts.2011.html
Anyway, congratulations and keep up the good work!

About the Monte Hall problem that was discussed in tonight’s TWIS, I’ve seen this discussed several times in Scientific American and some others science sources. I’ve always come to the conclusion that it is a 50/50 chance when you get to the point of making the final choice. Here’s why.
There are always three different prizes: a car, a middle prize (such as a TV), and a goat. I believe it was described on the show as two goats, but I’ve never seen it that way before; so, I think that was just stated wrong. If Monte has a goat, he always shows the goat first. That’s the important part. If he does not show a goat, he shows the TV, never the car. So, if Monte shows the TV, the player always trades; because, that means the player has the goat and Monte only has the car left. The player wins the car every time.
The player does not even start out with a 1/3 chance, because he/she already knows what happens if Monte first shows a TV. That possibility has already been dealt with. After that, all that is left is a 50/50 chance (the car or the goat).
So, If Monte first shows a goat, then the only two items left are the car and the TV. At this point, it becomes a 50/50 chance.
Drawing a chart shows this to be true. I’ll copy/paste my chart for you, but I don’t know if the software will keep the formatting. You may need to put it back into a table to see it clearly.
Player: car tv goat
Monte: tv goat car
goat car tv
Monte shows: goat goat tv
Player’s decision: 50/50 chance 50/50 chance 100 % trade
I’ve always read that the chances improve by trading because Monte has specific knowledge that the player does not have. However, that’s only part of the story. The player also has specific knowledge about what happens if Monte first shows the TV; he only shows the TV if the player has the goat. In order to make the trade always be the best choice, the rules of the game would need to be changed so that Monte can show whatever he wants the first time. However, he can’t do that, because in one of the three arrangements, he doesn’t have a goat to show. He can’t show the car first because that would ruin the game.
I was unfortunately right about the formatting. If you slide the line that starts with, “goat,” over one tab, I think you can see how everything should line up in a table.
I forgot to mention before that if the game is played so that Monte always shows the TV, rather than the goat, the analysis is exactly the same. The two items just switch places.
Your show is awesome! Don’t ever stop!
~jan 12, Justin joked that we might discover that we are actually made of antimater. I don’t know whether I think there’s a chance in hell this is possible. however, I think it was Edison that thought the electron was positive.
Hey guys great show, keep up the great work.
Here is a new topic to discuss on the show if you haven’t already heard (ancient humans using fire to cook?):

I still remember the first time I heard this podcast 5 years ago on the episode where Justin did his famous DISCLAIMER! about the equivalence of the NASA budget to how many coins you can stack to the moon and the blasting intro from High School Robot. I was just blown away that night sitting on a bus stop, waiting for a bus that comes only every two hours. I became a fan after that. I was a 27 year old, low-waged data-entry clerk without a college education and I’ve been unsure of what to do with my life over the past decade. It’s not until I listened to science podcasts like TWIS and TWIV that I began to reevaluate what I want in life. Your podcasts jump started me into going back to college to get an Associate in Arts for Teaching Secondary (Biology) for High School or Middle School. Your engaging and insightful conversations gave me something worthwhile to strive for where otherwise I was a little lost. Thank your Dr.Kiki and Justin for giving me a path that I can believe in and be proud of in life.
Will continue to listen down here in Miami.
thank you so much for sharing that!
*tears*
and with that, you just gave me a path I can believe in and be proud of in life too
Justin, are you still selling your novel?
can you enable subscribing to your show via google reader? many of the other twit shows allow this. it would be handy. keep up the great show!
That sounds like a great idea. How do I do it?
good question! Justin… if you are, we should put a link to it on this site to make it easy for people to find.
Each week I find myself scratching my head and wondering why this show isn’t grant funded and syndicated on public broadcasting (in addition to the TWiT podcast, of course)!
The chemistry is great. The tone is fun, smart, and enthusiastic. The topics are timely and interesting. I think it may be two factors that inhibit crossover to wider awareness and adoption:
1) The ad hoc conversation is not a format to which “big media” or the traditional media consumer is accustomed.
2) The conversation tends toward the technical or theoretical. Viewers have to be deeply engaged in order to discover the personal relevance of the topics.
A suggestion:
1) Record the show as two separate half-hour segments, with bumps on the ends. (Allows for more sponsorship and program scheduling options.)
2) Invite subject matter experts to submit brief video clips (20-60 seconds) explaining the relevance of each story (how it might affect the life of the viewer) and insert these clips after each story.
For instance, Neil Degrasse Tyson might explain why a new observation of dark matter might impact our mastery of physics. Steven Novella might explain how a neurological study could lead to a breakthrough drug or suggest a potential new therapy. Etc.
These “guest testimonials” would provide quick punches of obvious relevance, break-up the ad hoc conversation with traditional narrative, add dynamic content to the show, and possibly engage some “star power,” all of which might make grant providers, sponsors, media broadcasters and casual science enthusiasts perk up their ears a bit.
You would need a network of potential guests, who could provide a brief response the day prior to the show. (Justin, you would need to prepare your stories in advance. Sorry!) These wouldn’t need to be interviews. Guests could send self-recorded video or “Skype-in” to TWiT for a quick recording session.
Now, I’m rambling. Anyway. All this to say I love the ‘cast, look forward to it each week, and want an ever wider audience to enjoy it as much as do I!
New High Court Ruling in Australia, stated that the federal School Chaplaincy funding ruled unconstitutional. But unfortunately not due to the blatantly obvious conflict between church and state. It isecause legislation is not appropriate.

Hi, thanks for the awesome show, I look forward to it every week.
Do you mail World Robot Domination t-shirts to the UK?
I hope you do, I really want one.
Keep up the sciency awesomeness!!

I must echo the remarks from Brian (5-23-12 entry). You have a unique style and great interpersonal chemistry. I especially enjoy the debunking services you offer.

I would benefit from a chat room tutorial so I can read the ongoing conversation wehn I view the videos from Youtube. During TWIS maggeddon I could see remarks but could not find a place on my screen to contribute.
I just reinstated a $10/ month payment and a separate $210 contribution to express my appreciation for theheroic 21 hour extravaganza.
On a significant note, when can we expect to see Blair’s riveting Spider dance again?

The February 14, 2013 show.
I have been listening to the show for several years, at least since 2009. I think longer.
While I certainly like that you all enjoy and can have fun with the science topics I find the immaturity level of Blair to be darn near intolerable.
Here is a person that is suppose to be dedicating their life to science and disseminating the latest information about science to the general public yet she giggles and guffaws when ever something about sex is the topic. It really sounds like a junior high student doing a oral report on human reproduction.
This is actually my second comment about Blair. One was while she was an intern several years back and now this one. I am not sure who is the one making the decision about keeping her on the show or what the selection process was but I would highly recommend someone that was better able to communicate.
Justin and Dr. Kiki form a good team. While Blair has much to contribute it is a high price to pay for her childish laughter.
I will admit that she is significantly better at speaking than she was when she started.
Hi Thomas. Thank you for listening to TWIS for so long, and for your candor.
I respectfully do not agree with your assessment of Blair. I find lots of humor in topics related to sex, and many times laugh and make jokes myself. A significant part of this show is about finding the humor in science, and making it more relate-able. I think Blair brings wonderful insight to this show, and has been a valuable addition to our team. Whether or not you like her laugh is not something I’m particularly concerned with.
That said, I will take your comment into consideration as we report on sensitive topics in the future. We do reach a lot of people, and we really should think about what we say before we say it.
Hi,
I’ve listened to your show for a few years, and its been a refreshing look at Science – still is. I drive long distances and your show keeps me company….
Discovered recently that the Podcasts download to iTunes isn’t working. Last podcast is Feb 28.
Are you no longer on the iTunes auto-upload system? If so, how do I access your latest podcasts?
Thanks again for a great show,

Podcasts are coming out slowly. The only two people who are able to are Dr Kiki, who as we all know is quite busy (and she just moved, and has been in the process of the move for the past few months), and myself (I have no excuse, just a little busy and a bit lazy).
Hey, did you guys hear about the Glowing Plants project? First Syn-Bio Kickstarter funded within 2 days!
http://techcrunch.com/2013/04/23/glowing-plants/
Firstly. Blair is great, leave her alone Thomas!
Secondly, my real reason for writing here, in this week’s show (413) you discussed how early man might’ve got to Indonesian islands. You stated that it wouldn’t be possible to see the islands from elsewhere because of the distances involved (16 miles or so). Well the distance from England to France, across the Straits of Dover, is about 20 miles and, on a clear day it is possible to see France from England. So maybe the ancient peoples did make boats and paddle across to land that they saw?
I enjoy almost everything about the podcast, but more and more I am finding I am more disappointed then anything. I get that you are trying to make an entertaining podcast with humor, opinions, and some irreverence. I get this, and encourage it. Even when the opinions expressed are not shared by me, I recognize that the hosts are the ones putting themselves out there and that gives them the ability to express opinions.
What I am disappointed at is the lack of use of the scientific methods in your own discussions. For example in the March 28th you spoke of
* Healthier Fruit Flies — (great story, thanks for giving it some light), but no one mentioned the fact that to Fruit, a Fruit-Fly is a “PEST”. Hence fruit that has been grown ‘organically’ will be more susceptible to pests. This does not take away from this cool story, but it is an example among many of how the hosts could have stepped back from their opinions for organic.
* Fish For Fuel — Kiki, you did try to point out that the use of this organism as defined would not interfere with their continued natural existence. Far too much unnecessary and miss-informed opinion time given here. What are their environmental needs? How fast do they reproduce? How would we need to contain them to assure they don’t get into our environment where they shouldn’t be?
* Men vs Women — Lots of theories that this is nurture vs nature – boys brought up with goal oriented play (sports, cops/robbers, building), girls brought up to socialize and consensus build (dolls, crafts). Then there is discussion about colors pink (drunk-tank-pink) vs blue. Then, while you normally encourage new and crazy ideas, you totally shutdown Justin on his (silly and nutball) idea, ok likely that was right action.
* bacterial diet – Wouldn’t the fact that you are eating less food mean that there would be less surplus energy for the bacteria? Thus the bacteria collection would change. It is good to know that it changes in favor of weight loss. I was intrigued by the change in diet desires.
It seemed in early days, the stories would be picked apart from the science they imply or enable. Now days it seems the stories are just a jumping place for some personal agenda opinion. Kiki, I can tell you are trying. I appreciate every effort.
