A passer-by drops something and you spring to pick it up. Or maybe you hold the door for someone behind you. Such acts of kindness to strangers were long thought to be unique to humans, but recent research on bonobos suggests our species is not as exceptional in this regard as we like…

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,…

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…

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…

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…

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…

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…

Bees use their vision to navigate, but until now little was known about what happens inside their brains — which are smaller than a grain of rice — as they perform this task. “Polarized-light-based compass neurons and optic-flow-based speed-encoding neurons are located in a part of the bee brain called the central complex,”…

Scientists attending a recent meeting of the American Society for Microbiology reported they had uncovered a highly disturbing trend. They revealed that bacteria containing a gene known as mcr-1 – which confers resistance to the antibiotic colistin – had spread round the world at an alarming rate since its original discovery 18…

Two separate teams of researchers have used advanced DNA sequencing methods to analyze the 52,000-year-old remains of a Neanderthal woman from Vindija Cave in Croatia, and the 34,000-year-old remains of four anatomically modern humans from the Upper Paleolithic archaeological site of Sunghir. The findings are published in two papers in the journal Science. Kay…

Sixty years ago, a team of scientists went looking for yellow fever in the jungles that line the northwestern edge of Lake Victoria. What they found instead, in the blood of a rhesus monkey, was a new virus, one they named for the area’s dense vegetation: Uganda’s Zika Forest. Within a few years, Zika…

Patrick Allard, ISG faculty, along with Virginia Zaunbrecher, Elizabeth Beryt, Daniela Parodi, Donatello Telesca, Joseph Doherty, and Timothy Malloy, published the paper titled “Has Toxicity Testing Moved into the 21st Century? A Survey and Analysis of Perceptions in the Field of Toxicology” in the August 2017 issue of Environmental Health Perspectives. ABSTRACT: BACKGROUND:Ten years ago, leaders in…
