Prefer your coffee black? Then you probably like dark, bitter chocolate, according to new research identifying a genetic basis for those preferences.
"We developed molecular tools against many different parts of the HIV genome, so we were able to cut multiple genes out, which reduces the chance that the virus is going to replicate again," one researcher said.
Scientists temporarily attached a pig's kidney to a human body and watched it begin to work. What's it mean for life-saving transplants?
In 2005, researchers announced that they had successfully determined the gene sequence of the 1918 influenza virus. The virus was recovered from the body of a flu victim buried in the permafrost of Alaska, as well as from samples of American soldiers who fell ill at the time.
Scientists recently have found new ways to alter genes that may be safer than CRISPR. Gene editing also is being tested against diseases in children and adults, which is not controversial because those changes don't pass to future generations. Some scientists think gene editing will become more widely accepted if it's proved to work in those situations.
A forum was held in Berkeley, California, last month to get public views on gene editing — everything from modifying mosquitoes and crops to altering embryos.
The Chinese investigation seemed to confirm the existence of twin girls whose DNA He said he altered. The report said the twins and people involved in a second pregnancy using a gene-edited embryo would be monitored by government health departments. Nothing has been revealed about the third baby, which should have been born from that second pregnancy in late summer.
He Jiankui has not been seen publicly since January, his work has not been published and nothing is known about the health of the babies.
The largest study of its kind found new evidence that genes contribute to same-sex sexual behavior, but it echoes research saying there are no specific genes that make people gay.
Scientists have identified a "wake up" gene that may be responsible for activating the body's biological clock in the morning.
It's too early to tell, as the color of a baby's hair changes with time.
Some chickens lay white shell eggs and some lay brown shell eggs, similar to the way hair color varies in people.
How animals evolve and develop traits is basically the foundation of evolutionary biology.
New research conducted at Oregon Health & Science University in Portland, Ore., identifies a gene that could provide a new target for developing medication to prevent and treat alcoholism.
A Chinese researcher who sparked improved cognitive function in monkeys by implanting human genes into their brains has divided the scientific community.
A Chinese hospital has denied involvement in the alleged delivery of the world's first genetically-edited babies and experts worldwide have voiced outrage at such use of the technology.
There are multiple reasons why you may have differences in color between the two eyes.
