I've gotten some email asking for a simplified executive summary of this paper, so here it is.
A large study of almost a thousand autistic individuals for genetic variations that make them different from control individuals has found that Autism Spectrum Disorder has many different genetic causes: there isn't one single gene responsible for ASD, but a constellation of hundreds, each with the potential to affect the development of the brain and cause the symptoms of autism. They don't know exactly how each of these genes contributes to the disorder, but they have found that many of them are…
drorzel | June 10, 2010The Science Channel debuted a new show last night, Through the Wormhole with Morgan Freeman, with the premier apparently designed by committee to piss off as many Internet types as possible. The overall theme was "Is there a creator?" and it featured physicist-turned-Anglican-priest John Polkinghorne talking about fine-tuning but no atheist rebuttal. It spent a good ten minutes on Garrett Lisi and his E8 theory, making it sound a whole lot more complete than it is. And it got this aggressively stupid review in the Times:
Oh, let's face it: it was hard to concentrate on the first half of the…
drorzel | June 10, 2010One of the questions asked of Neil deGrasse Tyson at the WSF thing last week was "When did you change from a mild-mannered astrophysicist to a rock-star scientist?" (or something close to that phrasing). In his answer, he said that after his first tv interview was edited down to a three-second shot of him wiggling his hips, he made a deliberate effort to practice giving sound bites-- answering questions in 3-4 sentences with a good "hook" for the tv people to work with.
I thought of this when I stumbled across the following YouTube clips, which were shot by TV Ontario when I was at the…

The most recent issue of Scientia Pro Publica (Science for the People); "Scientia Pro Publica 32: Biology Overload" was published by Philip at his blog, The Dichotomous Trekkie 2.0. This was Philip's first ever blog carnival, and he did an excellent job! So go there, leave some warm fuzzies for Philip, then read the linked essays and be sure to leave your comments on at least one of those essays, either telling those authors what they did well, or making…
pontiff | June 8, 2010Fellow Yrekan Austin Sendek's quest to get "Hella" the official prefix for 1027 has scored a Googol-sized success. Err I mean a Google-sized success:
Austin also writes to inform me that there is an official petition, which can be found here.
Also I'm amused to note that the google-monster also recognizes smoots.
oracknows | June 7, 2010Orac is currently away at the ASCO meeting in Chicago. Shockingly, he was so busy that he didn't bother to write anything last night. Fortunately, he found something from the archives that's perfect for this occasion. Although it's not about ASCO specifically, ASCO is an even bigger meeting. This was originally written in 2005 on the "old' Respectful Insolence blog and then reposted in 2006. That' means if you haven't been reading at least three and a half years, it's new to you. It's also related to scientific meetings. Hmmm. This reminds me. I really should update this or do more…

drorzel | June 7, 2010In my write-up about the Hidden Dimensions panel, I mentioned in passing that:
I also would've liked to see an experimental physicist up there, to provide a little more grounding about what the actual problems are, and how you might hope to look for something. But then, I always think there should be more experimental physicists involved in everything.
I'm going to be traveling today, so I thought I would throw up a filler post offering a list of things that would be improved by the inclusion of an experimental physicist. Then I realized that that would be kind of difficult, as everything is…
rallain | June 7, 2010As part of the Ask a ScienceBlogger series, reader Jim Swanson asks:
When I open the dishwasher after washing and the contents are still hot, why do the glass and ceramic items dry off more quickly than the plastic items?
This is a great question. Great because it is something most everyone can relate to and great because there is some good science. Really, this shows the difference between temperature and thermal energy. I think the common idea is that temperature is a measure of the energy something has - but this isn't quite true.
Ok, let me first start with a sample case. Suppose you…

drorzel | June 6, 2010A great clip from his World Science Festival appearance the other night, especially the bit toward the end:
"One thing I think that as a nation we should be embarrassed by is that the scientists-- you can do this experiment yourself, I've done the experiment-- the scientists, by and large, know more liberal arts than the science that is known by liberal artists."
Or you can read my longer, less funny version from a couple of years ago. Either way, it's an important message: It should be exactly as embarrassing in educated company to say "I'm no good at math" as it would be to say "I'm no…

Books to the ceiling,

The Birdbooker Report is a special weekly report of a wide variety of science, nature and behavior books that currently are, or soon will be available for purchase. This report is written by one of my Seattle birding pals and book collector, Ian "Birdbooker" Paulsen, and is edited…
drorzel | June 6, 2010You might not know this, because I've been so shy about mentioning it here, but I'll be signing How to Teach Physics to Your Dog at 1:30 pm today as part of the Authors Alley program at the World Science Festival Street Fair. It's true.
It looks (at least in the tiny patch of sky I can see out our hotel window) like a beautiful day here in Manhattan, so if you're in the area, it would be a great day to come by an outdoor science festival. And given the stuff they were setting up last night, and the atmosphere at the events we've attended so far, it should be plenty festive, even if you're a…
drorzel | June 5, 2010Since I was going to be down here anyway to sign books at the World Science Festival Street Fair, Kate and I decided to catch one of the Saturday events at the Festival. It was hard to choose, but we opted for the program on Hidden Dimensions: Exploring Hyperspace (Live coverage was here, but the video is off), because it was a physics-based topic, and because I wrote a guest-blog post on the topic for them.
(No, we didn't go to the controversial "Science and Faith" panel, opting instead to have a very nice Caribbean dinner at Negril Village, just around the corner. I'll take excellent…
drorzel | June 5, 2010Over at Tor.com, Kate has a Lord of the Rings re-read post about the Battle of the Pelennor Fields, which includes a shout-out to me that I missed because I was driving to NYC:
Ãomer is "scarely a mile" away when the standard unfurls and is clearly seen to bear the White Tree, Seven Stars, and a high crown. If I were at home, I could ask the resident scientist to tell me how big these elements would need to be to be visible at a mile, but I'm finishing this post on the train down to New York City (vacation! Woo! I'm going to try and write the next post while I'm there, too, so as to make up…
drorzel | June 5, 2010We missed the formal presentaion at the World Science Festival stargazing event last night, and it was cloudy enough to prevent actual stargazing, but the giant mock-up of the James Webb Space Telescope is giant and cool even in the dark. More importantly, Neil deGrasse Tyson is awesome. We got there around 9:30, and he was taking questions from an informal group of people having around where the presentation had been. When we left at 11pm, he was still going strong. More amazingly, I don't recall seeing him drink anything.
He may be a robot. A really awesome robot who is amazingly generous…
drorzel | June 4, 2010Over at Inside Higher Ed they have a news report on complaints about the content of required reading for students entering college. This comes from the National Association of Scholars, a group dedicated to complaining that multiculturalism is corrupting our precious bodily fluids pushing aside the shared heritage of Western civilization, so most of it is pretty predictable. I was surprised by one thing in their list of commonly assigned books this year, though:
What are the freshmen reading? Based on the report's analysis of 290 programs (excluding books that are required parts of courses),…
oracknows | June 4, 2010Since its very inception five years ago, The Huffington Post has been, to steal a phrase from Star Wars, a wretched hive of scum and villainy, at least when it comes to anything resembling medicine. Of course, that's the problem. Very little, if anything, published in HuffPo resembles actual science-based medicine. The vast majority of medicine published there consists either of anti-vaccine screeds that are beyond stupid, quantum woo courtesy of Deepak Chopra, or pure, dangerous quackery, such as advocating homeopathy for H1N1 and acid-base woo for cancer. It's so bad that on more than one…
catdynamics | June 3, 2010A pair of papers just out show a mysterious absence of acetylene on Saturn's moon Titan.
Combined with a net flux of molecular hydrogen to the surface, this provides a tantalizing hint that there might be biochemistry taking place, with methane as the working fluid and hydrogen and acetylene as the primary energy source in a reductive metabolism.
Such a metabolic cycle was suggested five years ago by Chris McKay at NASA Ames.
The data, from NASA's Cassini Mission shows two hints of peculiarities.
C2H2 - acetylene is missing from the mix of nitrogen, methane and hydrocarbons seen in Titan's…
