The effects of impoundments are big one for people working in aquatic ecosystems. In Kansas, a large number of dams are still being built (and a lot more are in the discussion stages). So I am constantly trying to understand more about the effects of dams and the impacts they have on upstream and downstream aquatic ecosystems. I was recently forwarded the an article by Burke, Jorde and ... Read more »

David Cameron’s “Broken Britain”, with its image of moral decay driven by the breakdown in family life and poverty, may be inciting a lot of debate in parliament and the public press, but to read many studies of human evolution, you might be mistaken for thinking that the human male has never actually played a meaningful role in childcare. Most evolutionary studies focus on female life history – age at first reproduction, number of offspring and interbirth interval, for example – to th........ Read more »

Let’s say that you’re preparing for an extremely important test that you and roughly 100 other classmates will be taking in a week. A few days before the test, you find out that your instructor will be going on a trip not long after the test is over and will be providing written and verbal feedback to the students within a day of the test.
This is unusual, because ordinarily the instructor waits a week or more before providing feedback. About half of the class finds out that the........ Read more »

I've written a lot about bacteria and plants over the last few weeks, so in celebration of the fact that my project is finally on it's way out (with a whimper rather than a bang, unfortunately, but that's how it goes sometimes) I've decided to descend into the world of viruses. I've also decided to have a go at deconstructing some clinical papers, to make a change from academia. The difference between clinical and academic research can probably be described as follows (and I'm pretty sure I've s........ Read more »

Since Darwin, scientists have been theorizing as to why there is variation in brain size between species and individuals. Does a larger brain, in say humans, indicate advanced cognitive abilities and complex language processing? Or is a smaller brain, such as the Olive-backed thrush’s, adapted to weigh less to accommodate lengthy flights?
In psychology, the field of phrenology has generally been dissolved, and with it, the idea that variations in brain size could indicate differences ........ Read more »

Ever since the Soviet Union fell apart in 1991, Russian leaders have been vowing to transform their old-line, industrial society into a modern, knowledge-based economy driven by innovative science and technology.

Coca-Cola sucks India dry. Image: Carlos Latuff / Wikimedia CommonsThe marketing executive who came up with Coca-Cola's popular slogan in 1908 most likely never expected it would be taken so literally. However, a hundred years ago there probably weren't many who imagined a term like "water wars" could exist in a region that experiences annual monsoons.

Are we Africans different to the rest of the world in our giving, punishing and trusting behaviour? Three remarkable economic anthropology studies try to examine this kind of question with several ethnic groups in four countries: the Pimbwe, Sukuma and Kahama in Tanzania, the Maasai of Kenya and the Ju/'hoan Bushmen of Namibia and Botswana.

In a more specific manner this was established with Web Ontology Language OWL-DL, Protégé and Manchester OWL Syntax.With the SO-Ph........ Read more »

ResearchBlogging.org editor Dave Munger has written an article for SEED magazine entitled "Why do we believe". The article summarizes recent blog entries regarding studies on the origins of religiosity. It's really worth reading to get a good overview of the subject, and what do you know he links my entry on god's will and beliefs in it.
Among the studies that are mentioned is a controversial study entitled "Why Liberals and Atheists Are More Intelligent" (link at the end of this post).
