Experiencing sweaty palms, a rapid heart rate and nausea shouldn’t be the standard response before taking an important exam. However, for many students this has become a debilitating reaction when the pressure to perform academically affects their test scores. I became more aware of this situation when my 13-year- old niece started “choking under pressure” [...]... Read more »

According to the laws of physics when [calories in] exceed [calories out] people gain weight.
Unfortunately, when you actually deal with people (read: biological systems), this simple law is anything but simple. This is because, thanks to complex biological feedback mechanisms, designed by nature to keep us alive and thriving, changing caloric intake in turn affects [...]... Read more »

I don’t have much time this week and next to blog, but yesterday Science published an interesting paper by Hui Cao and colleagues at Yale that is hard to ignore. It is the ‘anti-laser’. In short, this anti-laser does exactly the same what a laser does, just with time reversed. You can do that because the [...]... Read more »

The ICU can be a terrifying place for an intern. Of course, the patients are probably a bit more frightened, but then, many of them are unconscious.

In my last post on koalas I discussed how they evolved to fit into a very specific ecological niche and how they lost some brain in the process.

The first detailed study of infection of nonhuman primates with the retrovirus XMRV reveals that the virus establishes a persistent infection characterized by infection of multiple tissues. Viremia (virus in the blood) is low and transient, with proviral DNA detectable in blood lymphocytes. The results show that the Rhesus macaque can be used to study [...]... Read more »

One of the problems with understanding the natural history of autism is the lack of well-designed outcome studies in the disorder. Outcome studies tend to be expensive and grant agencies commonly do not fund studies longer than a few years. However, given the increased interest and funding in autism, I suspect there will be more research in this area.An example of how outcome studies help in understanding the natural history of autism is a study published ahead of print by the Journal........
