The second part of the interview with Dr. Mark Lindeman is up on Neural Gourmet: Of public opinion, exit polls and fraud (or the lack thereof) (Part 2): Some people have referred to the "uncanny accuracy" of the exit polls. I think it's a very bad sign when the adjective "uncanny" drifts into…
Tangled Bank is up on Salto Sobrius.
Shakespeare's Sister has another article up on AlterNet: Bush gropes German Chancellor Angela Merkel Bush channeled the Creepy Guy at Work who gives a female coworker an unwanted massage, much to his repulsed target's chagrin. -------------snip----------- This is the ultimate in rude and…
Years of research die with specially bred lab mice: When a power failure triggered the death of nearly 600 mice at Ohio State University last week, a group of researchers lost more than their lab rodents. Mary Cheng lost years of insight into the human brain. Caroline Whitacre lost a better…
Reed Cartwright, the blogger of De Rerum Natura and Panda's Thumb fame, has moved to my neighborhood (OK, 28.7 miles from me), getting ready to start his postdoc at NCSU. A loss for Georgia is a gain for North Carolina. I hope he enjoys the vibrant local blogging community.
Keyboard screwed up! Bakspace, Delete, 1st, 3rd, 5th, 7th key on high row do not work (q, e, t, u, and a). Does anyone know what could be wrong? (using onscreen keyboard to type this) Update: I bought a new one and it works fine....
Scientists Discover Why Cornea Is Transparent And Free Of Blood Vessels, Allowing Vision: The key, say the researchers, is the unexpected presence of large amounts of the protein VEGFR-3 (vascular endothelial growth factor receptor-3) on the top epithelial layer of normal healthy corneas.…
Kevin goes on a huge hike, finds an enormous snake, watches another snake eat a frog, carries a snake for 45 minutes in his hands, gets bitten by a pseudocobra, drinks five liters of stream water and gets sick....all in great detail under the fold.... Bancang (Bantong) 10 July Today the plan was to…
I love my kids, and they are growing into wonderful, passionate atheists. This one is from March 24, 2005, under the fold.... The kids' spring break just started, the weather is gorgeous, and the computer is broken. What a great opportunity to spend a lot of time together (instead of timing each…
Apparently there is a meme going around the blogosphere in which people dig into their personal libraries on a search for the oldest book they have - originals, that is, not reprints or printouts. Considering that I am a book lover and a book hoarder, I was surprised to see how few of my books are…
Grand Rounds Vol. 2 No. 43: It's all about the ladies is on ChronicBabe
?? Which Creature Of The Sea Are You?? SeahorseTake this quiz! Quizilla | Join | Make A Quiz | More Quizzes | Grab Code Well, the questions are kinda iffy, so when I did the quiz the second time around with alternate answers, I got a cephalopod after all, and a description that fits…
Mark Lindeman is a guy who did the statistical analysis of the exit polls and final numbers of the 2004 election and conluded that there was NO fraud, or at least not enough to make a difference. He is, thus, a liberal unloved by some other liberals. He is thus a liberal unhappy that his data…
Do you think YOU can solve this puzzle? Go see the first three clues, the fourth clue and the final clue. Any ideas?
From Financial Times: 'Social jet lag' causes fatigue and illness (also on MSNBC): Half the people in modern urban societies suffer from "social jet lag" because their body clocks are seriously out of step with their real lives, the Euroscience forum in Munich heard on Monday. The result was…
Here is a little tangent to Kevin's adventure. You may recall from one of the previous installments (Kevin in China, part 6 - The Mystery Snake) that there was an evening that Kevin does not remember very clearly, due to great hospitality of his hosts and the high alcohol levels of the wine served…
This post about the origin, evolution and adaptive fucntion of biological clocks originated as a paper for a class, in 1999 I believe. I reprinted it here in December 2004, as a third part of a four-part post. Later, I reposted it here. III. Whence Clocks? Origin, Evolution, and Adaptive Function…
New Carnival of the Green is up on Powering Down.
David Ng of Science Fair is asking an informal AskThe ScienceBlogger question: Are there any children's books that are dear to you, either as a child or a parent, and especially ones that perhaps strike a chord with those from a science sensibility? Just curious really. And it doesn't have to be a…
Ingeo is a fabric made out of genetically engineered corn - one more way the agricultural-military-industrial complex is finding a way to get you to consume all those tons of corn they are paying the farmers to grow. Fashion of future may grow in cornfield: ``We think there is a tremendous future…
The latest question in the Ask A ScienceBlogger series is actually not that easy to answer, though some have, so far, valiantly tried: Is every species of living thing on the planet equally deserving of protection?... My attempt at the answer is under the fold.... My first knee-jerk answer is "Yes…
The second edition of Encephalon, the neuroscience carnival, is up on Pure Pedantry.
Chris Clarke is equally surprised. At this rate, we'll have a tropical rainforest there soon.

Do you read Darren Naish's blog Tetrapod Zoology? If not, you should start now. Just check out some of the most recent posts, for example this two-parter on sea snakes: 'A miniature plesiosaur without flippers': surreal morphologies and surprising behaviours in sea snakes and Sea kraits: radical…

Tar Heel Tavern #73 is up on A Sort of Notebook.
Interview with John Edwards on Southern Studies. Instapundit thinks that Edwards on the top of the ticket could have won in 2004. Ed agrees and points to an interesting post by Instalawyer. As usual, frightened Republicans in the comments trot out the hair and some errors or fact....
I am teaching the Intro Bio lab right now and thought it would be appropriate to schedule this post to appear at the same time. I wrote it last time I taught this, but today's lab will be pretty much the same. Being second summer session, the class will probably be really small, which will make…
