NEW YORK (AP) — With two pairs of fine-tipped tweezers and the hands of a surgeon, Cheryl Hayashi began dissecting the body of a silver garden spider under her microscope. In just a few minutes she found what she was seeking: hundreds of silk glands, the organs spiders use to make their webs. Some...

This microscope image shows the 46 human chromosomes, blue, with telomeres appearing as white pinpoints. Research released on Tuesday, July 16, 2019 offers some of the first biological clues to why women may be more likely than men to develop Alzheimer's disease, and how this most common form of dementia varies by gender.

LOS ANGELES (AP) — New research gives some biological clues to why women may be more likely than men to develop Alzheimer's disease and how this most common form of dementia varies by sex. At the Alzheimer's Association International Conference in Los Angeles on Tuesday, scientists offered evidence...

NEW YORK (AP) — Inside an Indiana aquafarming complex, thousands of salmon eggs genetically modified to grow faster than normal are hatching into tiny fish. After growing to roughly 10 pounds (4.5 kilograms) in indoor tanks, they could be served in restaurants by late next year. The salmon produced...

DURHAM, N.C. (AP) — A panel of top scientists has concluded the endangered red wolf of the southeastern U.S. is a species unto itself. The study by the National Academy of Sciences gives the beleaguered canine a scientific and political boost as its numbers plummet in the wild. The panel also found...

This March 2019 image shows part of the health advice option in a 23andme genetic test. But Isaac Kohane, a biomedical researcher at Harvard, said research in the field is still limited and that there’s little evidence any small effects from genetic variations can be translated into meaningful dietary advice.

NEW YORK (AP) — Avoid fast food, eat vegetables and exercise. It sounds like generic health advice, but they're tips supposedly tailored to my DNA profile. The suggestions come from 23andme, one of the companies offering to point you toward the optimal eating and exercise habits for your genetics...

A scientist at the NY Genome Center in New York demonstrates equipment used in single-cell RNA analysis on Wednesday, Sept. 26, 2018. Until recently, trying to study key traits of cells from people and other animals often meant analyzing bulk samples of tissue, producing an average of results from many cell types. But scientists have developed techniques that let them directly study the DNA codes, and its chemical cousin RNA, the activity of genes and other traits of individual cells. (AP Photo/Malcolm Ritter)
