Why do male chicks play more than females? Study finds answers in distant ancestor
Play is widespread, but far from ubiquitous, across the animal kingdom. Especially common in mammals, play is also known to occur in taxa as diverse as birds, fish, octopuses, and even insects. But what is its function, given that natural selection n.....»»
Alpacas found to be the only mammal to directly inseminate the uterus
A pair of biologists from Mount Holyoke College, working with a colleague from North American Camelid Studies Program, the Nunoa Project, has found that the male alpaca thrusts his penis all the way into the uterus of the female during mating, making.....»»
Long snouts protect foxes when they dive headfirst into snow, study finds
When hunting for mice in winter, red and Arctic fox are known to plunge headfirst at speeds of 2–4 meters per second, but their sharp noses reduce the impact force in snow and protect them from injury, according to a new Cornell University study......»»
Cartilage healing discovery in animal models could lead to new human therapies

Exploring why young women in Australia are reluctant to enter politics
Despite growing momentum to increase female representation in Australia's national parliament, it continues to be a male dominated domain. New research from Monash University explores why young women still feel reluctant to become a member of the nat.....»»
Researchers find babbling by zebra finch chicks is important step to memorizing songs
When babies learn to talk or birds learn to sing, the same principle applies: listen and then imitate. This is how the first babble becomes the first word or vocalization. Male zebra finch chicks initially memorize the song of an adult bird. Later, t.....»»
Older male blue tits out-compete young males when it comes to extra-marital breeding
Young male blue tits are less successful in fathering offspring outside their breeding pair, not because of a lack of experience, but because they are outcompeted by older males, Bart Kempenaers and colleagues from the Max Planck Institute for Biolog.....»»
Bonobos are more aggressive than previously thought, study shows
Chimpanzees and bonobos are often thought to reflect two different sides of human nature—the conflict-ready chimpanzee versus the peaceful bonobo—but a new study published in Current Biology shows that, within their own communities, male bonobos.....»»
