How many species are there here? It’s a beguilingly simple question, and a fundamental area of interest. A moments thought shows that the bigger here is, the more species there will be. So, if we start from a little patch of my lawn, and take successively larger heres until we’ve included the whole world, we [...]... Read more »

Like atlatls, but to an even greater degree, bows are rare in the archaeological record because they were made of perishable materials. While some types of atlatls had more durable attachments such as hooks and weights, bows were almost always made of wood and various fibrous materials, except in some areas where they were made [...]...

Young adults in the USA are more likely than ever before to tell pollsters that they don't see themselves as 'being' of any particular religion - they are unaffiliated. The data are clear, but the reason for this shift is not.
It might simply be their age. Maybe they will be more likely to identify with a religion when they're older. Alternatively, there could be an uptick in the numbers of people who are leaving religion - for good.
Or maybe it's a snowball effect. More than ever before, Amer........ Read more »

The 2,000 year dance between the Jewish people and Western civilization has spawned many questions of scholarly interest. A relatively minor point, though not trivial, has been the issue of the biological relatedness of the Jewish people, and their relatedness to the nations among whom they were resident. This particular point became more starkly relevant [...]... Read more »

Kevin Zelnio of Deep Sea News tweeted the title of this piece and sent my mind going over the various theories of citation, what citations mean, studies showing how people cite without reading (pdf) (or at least propagate obvious citation errors), and also how people use things but don't cite them in certain fields...

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 »

Before I was introduced to wikis in April 2008, I never would have envisioned how much my teaching could use these new technologies. More importantly, my students could not be more ready to take their education to a new level that I sincerely hope will better connect them to the world and prepare them to participate in a digital world. The time is now, and while students have been hungry for this opportunity, the reinforcing research is thorough enough to justify using wikis,blogs, podcasts, F........ 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 »

One of the most interesting things about exercise is that it results in important health improvements even in the absence of weight loss. For example, just a single session of exercise can result in improved insulin sensitivity, increased levels of HDL cholesterol (aka the "good" cholesterol) and reductions in plasma triglyceride levels - all tremendously important markers of disease risk. In addition to these metabolic changes, new research by our friend and former labmate Lance Dav........ Read more »
