Jonah at The Frontal Cortex posted a great article exposing the limits of genetic determinism. Sometimes a genetic explanation seems so obvious, but further study shows that environment also plays a prominent role. Definitely read the whole thing.

What does a scanner see? Into the head? Into the heart? Does it see into me? Clearly? Or darkly? Think about it this way. Everything that you have ever been or ever will be, everything you have loved, every preference, every joy, every sweet or sordid memory is contained in a squishy mass of about…

...I am just concerned that she needs to stay out of the sun because being a redhead she is at high risk for skin cancer: Fair-skinned redheads are known to have increased risk of developing melanoma. Now researchers may have pinpointed one of the reasons: variations in a gene called MC1R. This…

Every time I think that Britney Spears cannot become more trailer trash, she goes and becomes the black hole into which all other trailer trash in the Universe is sucked: That would be Britney Spears in the latest issue of Bazaar being her very pregnant self. 1) That was disturbing when Demi Moore…

This weeks Ask a Scienceblogger is: What are some unsung successes that have occurred as a result of using science to guide policy? I don't know if this is unsung but it bears repeating because it is truly a triumph of science over those who would prefer the research had not been done. In 1964, the…

When a man wakes up after a 20 year coma, you know that people are going to pay attention. Particularly after the Terry Schiavo business, I think it is important to add some facts to this debate as early as possible before it gets completely out of control. So let's talk about this guy. In 1984…

Neurodudes has an excellent article on software intended to reduce medical errors. Just from my limited personal experience, I would say that such software would be useful if people understand that it is limited in scope. There are three general reasons I think that software is useful in…

In 4th of July related news, Takeru Kobayashi has yet again proven that stomach size and total body size have no clear correlation. A 160-pound wonder from Japan set a new record by devouring a sickening 53 3/4 frankfurters in 12 minutes to win the annual Independence Day hot dog eating competition…

You remember what you learned in biology right -- or maybe health. A woman is born with all the eggs she will ever have. Well some researchers in Australia are disputing that point. By doing stereology on mice aged 1 to 200 days they claim to show that the overall number of eggs does not…

When you get in a conversation about pharmaceuticals, everyone always asks me: "Why can't they just give them away? Drug companies make so much money anyway. Why do we even have patents?" Well, the reason is that piracy stifles innovation. If people can't make any money off what they make,…

Hellllloooooo, love-dart. When molluscs mate, the male shoots this little spear into the female depicted here protruding from the female's head: Hot. But why all the she-snail hating. Chase and Blanchard show in this work that the purpose of the dart is for the male snail to convey his man mucus…

What is wrong with this picture? It's wrong for one. What this picture represents is what is called the "motor homunculus." The motor homunculus is the idea that on a particular gyrus of the brain -- the precentral gyrus -- all muscle are represented by discrete pools of neurons. Activation of…
