Parents each pass on two genes for eye color, or so your teacher probably told you. Sorry to break it to you, but very few traits actually work this way. With more genetic information available, it’s becoming clear that a number of different genes determine each feature.

Wild chimpanzee females in western Tanzania who leave home or are orphaned take roughly three years longer to start a family. The researchers analyzed more than 50 years’ worth of daily records for 36 female chimps born in Gombe National Park.

In a new study, MIT researchers have developed nanoparticles that can deliver the CRISPR genome-editing system and specifically modify genes in mice. The team used nanoparticles to carry the CRISPR components, eliminating the need to use viruses for delivery.

A study tracked the eye movement of twins finds that genetics plays a strong role in how people attend to their environment. The study offers a new angle on the emergence of differences between individuals and the integration of genetic and environmental factors in social, emotional and cognitive development.

Researchers in the University of Wisconsin–Madison Department of Biochemistry have discovered that a cellular pump known to move drugs like antibiotics out of E. coli bacteria has the potential to bring them in as well, opening new lines of research into combating the bacteria.

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 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 to think.

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.

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.”

Through the Middle East and Turkey, it’s thought that the ancestors of modern humans 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 spot where it happened.

In 2013, an influenza virus 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.

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.

When encountering a female, a male mouse will try to mate with it, and when encountering another male, the mouse will attack. The animals don’t have to be taught to perform these behaviors. This has led to the presumption among neuroscientists that the brain circuits mediating these behaviors are “hardwired.”
