Electroconvulsive therapy (ECT) is a crude but effective treatment for depression. It consists of applying a brief alternating current to the brain in order to induce a generalized seizure, which usually lasts for less than half a minute. It looks nothing like the picture to the left.ECT is typically given three times per week, and a dozen sessions are enough to produce a dramatic improvement in depression in most cases. However, how it works is entirely mysterious. There are plenty of theories......... Read more »

Many farmers throughout Latin America and around the world rely on pesticides to control pest invasions; in the case of Andean potato crops, this method is not only costly but has been shown to cause adverse health effects as well. Due to the risks involved in pesticide usage, and the ever-increasing demand for high-yield crops, new methods of controlling pest invasions are being explored by researchers regularly. And as counterintuitive as these new findings sound, ecological scientists have d........ Read more »

As marine scientists, sometimes we forget or don't even realize how much local baymen and fishermen actually know. Or maybe we don't trust them because they are "lay" persons. But they work the bay, they try to catch many of the species we study (as money is a big driver of research), and they know things. Local baymen who have worked the bay for years suggest that bay scallop recruitment is higher in years after cold/wet winters. Sometimes, we take what they say with a grain of salt. Howev........

It’s good to be omniscient.
Only a few natural studies have been able to approach that level of knowledge. Peter and Rosemary Grant come fairly close in some seasons studying finches on the smaller Galapagos Islands. A new paper must must surely be a contender for god-like knowledge of a population of animals.

The skull of a spotted hyena (Crocuta crocuta), photographed at the AMNH's "Extreme Mammals" exhibit.
There was something strange about the assemblage of Homo erectus fossils found at Zhoukoudian - the famous 750,000 - 200,000 year old site in China popularly known as Dragon Bone Hill. Despite the abundance of skulls and teeth, there were hardly any remains of the hominins from below the neck. Where were the bodies?
The majority of Homo erectus fossils from Zhoukoudian were discovered and s........ Read more »

The model for bacterial death by antibiotics was fairly simply until recently. Antibiotics work by targeting a certain area of the bacteria; beta-lactams target the cell wall, Rifamycins target RNA synthesis, tetracyclins inhibit protein synthesis etc. The theory was that by inhibiting these processes, a certain vital function within the bacteria would be stopped, leading to its death.However due to research done by Kohanski (references below) the story is looking a bit more complicated. Looking........ Read more »

It turns out birds aren't bird brains when it comes to what they eat. A number of species of birds have been shown to choose foods that contain higher levels of healthy things like protein and antioxidants and lower levels of not-so-healthy things like heavy metals and pesticides. Since they're suck finicky eaters, scientists figured to let them choose between conventionally and organically grown food, and see which they deemed better for them. The vote was unanimous: birds prefer non-organic.... Read more »
