Old and healthy: Researchers find novel genes for longevity in mammals

The genetic basis of lifespan determination is poorly understood. Most research has been done on short-lived animals, and it is unclear if these insights can be transferred to long-lived mammals like humans. By comparing genes of long- and short-lived rodents, researchers from Leibniz Institute on Aging (FLI) in Jena/Germany now identified in a collaborative project...

Island emus’ size related to size of island homes

Emus that lived isolated on Australia's offshore islands until the 19th century, including Kangaroo Island, King Island and Tasmania, were smaller versions of their larger mainland relatives -- and their overall body size correlated to the size of the islands they inhabited.

Published today in the journal Biology Letters, this was the surprise finding of a...
