Oldest fossil of a flying squirrel sheds new light on its evolutionary tree

The oldest flying squirrel fossil ever found has unearthed new insight on the origin and evolution of these airborne animals.

Writing in the open-access journal eLife, researchers from the Institut CatalĂ  de Paleontologia Miquel Crusafont (ICP) in Barcelona, Spain, described the 11.6-million-year-old fossil, which was discovered in Can Mata landfill, approximately 40 kilometers outside the city.

A study of hundreds of captive chimpanzees showed that males that get along well with others -- by being sensitive, protective and cooperative -- outlived their less amiable peers.

The team, led by researchers at the University of Edinburgh, found...

New knowledge about retrovirus-host coevolution

Retroviruses have colonised vertebrate hosts for millions of years by inserting their genes into host genomes, enabling their inheritance through generations as endogenous retroviruses (ERVs). Researchers from Uppsala University now provide new knowledge about the long-term associations of retroviruses and their hosts by studying ERV variation and segregation in wild and domestic rabbit populations. The...

How wasp and bee stinger designs help deliver the pain

Next time you're stung by a wasp or a honeybee, consider the elegantly designed stinger that caused you so much pain.

In a new study, researchers found that the stingers of the two species are about five times softer at the tip than at the base to make it easier to pierce your skin. The stingers...

Getting a grip on the slow but unique evolution of sharks

Scientists at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan, in collaboration with other Japanese institutes and aquariums, have decoded the whole genomes of two shark species for the first time and improved the whale shark genome sequences released previously. By analyzing the genomes and comparing them with those of other vertebrate species,...

Bag a job, bag your prey

How many jobs should an applicant consider before accepting the next job offer? Turns out the same decision-making process that goes into searching for a job also applies to hunters searching for prey, and the knowledge can be used in conservation.

In a new study published today, researchers used a job search theoretical model to better...
