According to a new June paper in Human Nature, the reactions of chimpanzees to videos showing violence against an infant chimp reveal that chimpanzees can recognize putative social norms. The chimpanzees did not, however, react in strongly negative ways – showing that chimpanzees may not intervene or protest if the […]

Researchers at the University of Vermont have discovered a link between eye color and alcohol dependency in Americans of European descent. Northern Europeans might have evolved light eye traits as an adaption to darker environments because lighter eyes provide a greater sensitivity to light (1). But an increased sensitivity to […]


A discovery in fluid dynamics with cosmological implications

The inflationary universe: A new discovery in relativistic fluid dynamics could help scientists understand the expansion and fate of the universe.

Normally, fluid dynamics and cosmology are widely separate disciplines. Problems like the flow of water through a pipe have little to do with the evolution and fate of the universe; but, as it turns out, if one allow fluids to move near the speed of light, one will find some interesting properties […]


High testosterone levels in female athletes: Weighing in on the debate

In a recent case at the “Supreme Court of Sport” in Switzerland, female Indian sprinter Dutee Chand challenged a policy that prevents women with naturally high testosterone levels from competing against other female athletes. The policy, enacted by the International Association of Athletics Federations (IAAF), prohibits women whose testosterone levels […]


Clams Discovered to Have Contagious Cancer

Clams Discovered to Have Contagious Cancer

It has long been thought that cancer is not contagious. Recent discoveries, however, have suggested otherwise. A venereal disease in dogs as well as facial tumors in Tasmanian devils have previously been identified as transmittable cancers, and this week, researchers at Columbia University found that a third cancer belonged to this group: hemic neoplasia. This cancer was first noticed in […]
