Sex is an expensive way to make a copy of yourself. A plant that reproduces sexually has to build flowers and make pollen, and then take apart the very combination of genes that carried it through…
Researchers at Boston Children's Hospital have reported a way to insert whole genes at a chosen point in the human genome without cutting both strands of the double helix and without waiting for the…
Researchers have built a combined genetic map of cultivated peanut and used it to read the DNA of 2,320 accessions, meaning distinct samples held in a seed bank. The work was published on September…
Researchers who analyzed the genetics of Alzheimer's disease separately in carriers and non-carriers of the high-risk ε4 version of the APOE gene found nine genetic signals for the disease that never…
Genetic risk scores for common diseases predict less accurately for a person the further that person's ancestry sits from the group the score was built in, and the decline follows a straight line.…
A blood test that can flag Alzheimer's disease before symptoms appear predicts how soon those symptoms arrive more sharply when it is read alongside a common gene result, a Columbia University-led…
A gene-editing tool that changes a single letter of DNA without cutting through the double helix altered every copy of the cholesterol gene PCSK9 in human embryos, a study published in Nature on…
A genome sequence can end a family's search for an answer, and it can also hand them a list. Among the millions of spelling differences that make one person's DNA unlike anyone else's, a clinical…
In maternity wards in New Orleans, Omaha, the Twin Cities and New York City, women who had just given birth were handed a debit card and told it would be topped up on the same day every month until…
Jian Li, Peng Yi and colleagues at the Joslin Diabetes Center at Harvard Medical School report that switching off a single gene turned human pancreatic duct cells into cells that make insulin, and…
Two teams published large genetic studies of multiple sclerosis in Nature Genetics on Sept. 7, both using patient groups beyond the European-ancestry populations behind most of the field's data. One…
Melon seeds are a problem on an archaeologist's table. They turn up at Chinese sites, small and flat and stubbornly anonymous: melons, cucumbers and their wild relatives all belong to the genus…
