Light. It’s all around and is the foundation of much of planet. Plants on land or in the shallow seas use the power of light to catalyze a cascade of interactions that ultimately result in the foundation of our planet. Even in the deep sea the products of light find their way [...]... Read more »

So this week seems to be turning out to be cooperation week. We talked about cooperative behavior of the proteins that make up the cytoskeleton on Monday, cooperation in breeding behavior in birds on Wednesday, and now it’s time to talk about cooperative behavior in bacteria. If only I’d planned it in advance. Ah well; [...]... Read more »
An unusually gripping genetics paper from Biological Psychiatry: Pagnamenta et al.The authors discuss a family where two out of the three children were diagnosed with autism. In 2009, they detected a previously unknown copy number variant mutation in the two affected brothers: a 594 kb deletion knocking out two genes, called DOCK4 and IMMP2L.Yet this mutation was also carried by their non-autistic mother and sister, suggesting that it wasn't responsible for the autism. The mother's side of the f........ Read more »

Have you been in a situation where you are the first to detect a cardiac murmur in a patient? If you are hearing it in a busy, loud Emergency Department, I find that it's at least a grade III. Should you order an echocardiogram for further outpatient evaluation? It depends on the grade and characteristic of the murmur, in addition to the patient's symptoms. For instance, all diastolic murmurs require an echo. There is a useful ACC/AHA algorithm which helps you decide.Thanks to Amy Kinard, an Eme........ Read more »

Evolutionary Anthropology has a nice paper summarizing the history of domestic cattle, based on the latest molecular marker data.

It was a rare bit of good news.

A new study identifies a likely cause of rapid degeneration in some Alzheimer's patients. The results of this study may lead to improved treatment.

Subliminal priming is a cool psychological trick that can change the way you think or the things you do without you even being aware of it. So, for example, you do a word puzzle that includes religious words, and chances are you'll behave more honestly later.
Which brings us to the Golden Rule. This is one of those basic components of human morality that pops up in pretty much every culture - the British Humanist Society even produces a poster with 20 different versions from around the world. T........ Read more »

We’ve all been there — sitting in a public place, and feeling like that person over there, talking on their cell phone, is so annoying. Why are they so annoying? What makes a cell phone conversation that you overhear so distracting?
Four researchers, led by Lauren Emberson (2010) from Cornell University, set to find out.
Previous research has shown that we don’t seem to be as distracted when listening to a full dialogue between two people as when we are listening to a “h........ Read more »

The tumor suppressor p53 is one of the cell’s very best friends. Just how good a friend it is becomes apparent when, just like in other relationships, this particular relationship turns sour. p53 is the “master guardian angel” of the genome and constitutes the most frequent genetic alteration in cancer. More than 50% of human tumors contain a mutation in the p53 gene. With this kind of glowing track record, p53 would be a prime target for drugs.It turns out that discovering drugs for p53 i........
