First Hibernating Primate Found Outside Madagascar : Discovery News

… typically weighing about 1 pound. The nocturnal creature lives in trees and, unlike other primates, it can’t leap. Its diet includes tree gum, insects, and fruit. The scientists studied the animal’s body temperature in the fall, winter and spring in Vietnam. They found that the creature engaged in episodes of hibernation between December and February that lasted up to 63 hours each. The researchers suspect both an internal clock mechanism that kicks in during seasons of food scarcity …

A cray-active solution for cancer research

… new environmental conditions such as diet, population density or temperature. “Epigenetic factors may also influence cancer risk and play a role in the clinical development of the disease,” says Lyko. For example, colleagues at DKFZ have recently shown that epigenetics plays a major role in medulloblastoma, an aggressive brain tumour in children (DKFZ PM Nr. 30/2014). Lyko explains that, “in order to understand the basics of epigenetics, we need models. The usual mouse and rat …

Bird poo spider fires up Hilton

… species also spins a web around its resting place so it looks like splatter from the dropping. After discovering the new species in 2006, Roff went through the ­process of naming the spider and publishing his research on the spider in the African Invertebrates scientific journal. The species is the 13th spider of the Pasilobus species. The spider has an unusual diet, feeding only on male moths which it attracts by releasing a scent similar to that of a female moth. When the male moth …

The role of species competition in biodiversity

… from around 40 million years ago to the present; theorizing that competition from other species was a factor driving extinction rates, they also compiled data for five additional carnivore families including cats, bear dogs, false saber-tooth cats, and bears. They developed an analytical framework to invesigate whether speciation and extinction rates responded to evolution of body mass—a good approximation of diet for canids. The authors suggest that body size can indirectly correlate with …
