Same-sex sexual behaviour is common in animals but puzzles evolutionary biologists since it doesn't carry the same obvious benefits as heterosexual courtship behavior that leads to mating and production of offspring. A study from Uppsala University sheds new light on the pervasiveness of same-sex sexual behaviour in the animal kingdom.

Having analyzed the data collected for more than three decades, scientists managed to show that the effects of climate changes in the Arctic may come out on a completely different continent, a few thousand kilometers away from the Arctic ice. One of the authors, Eldar Rahimberdiev, researcher at the Biological faculty of MSU, says that the work is unique, as earlier scholars did not consider these problems so complex.

Although ski season is behind us, serious skiers are already looking ahead to next season and searching for ways to shave split-seconds off their race times. Now scientists may have a new way to help -- perhaps in time for the next Winter Olympics. One team has determined how the microscopic texture of the bottoms of skis could affect their speed, depending on snow temperature. Their study appears in the journal ACS Applied Materials & Interfaces.

Why is the WebMD website so successful? Last week, John Oliver ridiculed them for promoting every suspect association between anything and cancer, without any analysis or critical thinking. 

A new paper paper in the journal Communication Research may provide some answers. They are publishing churnalism and advertorials about science and health, and that is far more effective than the numerous advertisements they carry.

Diagnoses of celiac disease (CD), an autoimmune disease, are increasing, no real surprise after not one but two bestselling food books based on suspect studies claimed wheat is poison.

Psychologically, women may not like much competition, according to a female psychologist, and that may account for inequality in academia and the work force.

If that is true, though, why is psychology 70 percent women? There is just as much competition, it just isn't men. It may be that because psychology has a smaller monetary reward, women feel more communal than competitive, according to Dr. Kathrin Hanek, the study's lead author.
