A UCLA research team led by Patrick Allard, assistant professor of society and genetics, has been awarded a $1.1 million grant from the John Templeton Foundation as part of the foundation’s funding efforts for research into genetics. The project’s co-leaders are Amander Clark, associate professor of molecular, cell and developmental biology, and Hannah Landecker, director of the UCLA Institute for Society and…
Wild fruit bats, living in crowded roosts, are exposed to calls from hundreds of fellow bats from birth. Most often these calls are made in response to unsolicited physical contact, and essentially amount to a crabby “move out of my way.” In a study published Wednesday in PLOS Biology, a team of Israeli researchers found that bat pups match their vocalizations…
When the ancestors of modern humans migrated out of Africa, they passed through the Middle East and Turkey before heading deeper into Asia and Europe. Here, at this important crossroads, it’s thought that they encountered and had sexual rendezvous with a different hominid species: the Neanderthals. Genomic evidence shows that this ancient interbreeding occurred, and Western Asia is the most likely…
In 2013, an influenza virus that had never before been detected began circulating among poultry in China. It caused several waves of human infection and in late 2016, the number of people to become sick from the H7N9 virus suddenly started to rise. As of late July 2017, nearly 1,600 people had tested positive for avian H7N9. Nearly 40 percent…
Not long ago, a lengthy drive on a hot day wouldn’t be complete without scraping bug guts off a windshield. But splattered insects have gone the way of the Chevy Nova — you just don’t see them on the road like you used to. Biologists call this the windshield phenomenon. It’s a symptom, they say, of a vanishing population. “The windscreen phenomenon is probably one of the best illustrative ways…
Adult male mice have a simple repertoire of innate, or instinctive, social behaviors: When encountering a female, a male mouse will try to mate with it, and when encountering another male, the mouse will attack. The animals do not have to be taught to perform these behaviors. This has led to the widespread presumption among neuroscientists that the brain circuits…
