A gene-editing first: scientists tried CRISPR to fight HIV

Sep. 11, 2019 5:03 PM EDT

Scientists are reporting the first use of the gene-editing tool CRISPR to try to cure a patient's HIV infection by providing blood cells that were altered to resist the AIDS virus. The gene-editing tool has long been used in research labs, and a Chinese scientist was scorned last year when he revealed he used it...

Scientists rethink Alzheimer's, diversifying the drug search

Sep. 10, 2019 2:58 PM EDT

WASHINGTON (AP) — When researchers at the University of Kentucky compare brains donated from people who died with dementia, very rarely do they find one that bears only Alzheimer's trademark plaques and tangles — no other damage. If they do, "we call it a unicorn," said Donna Wilcock, an Alzheimer's...

New genetic links to same-sex sexuality found in huge study

Aug. 29, 2019 2:41 PM EDT

CHICAGO (AP) — The largest study of its kind found new evidence that genes contribute to same-sex sexual behavior, but it echoes research that says there are no specific genes that make people gay. The genome-wide research on DNA from nearly half a million U.S. and U.K. adults identified five genetic...

Library of spider silk could hold secrets for new materials

Aug. 14, 2019 12:12 PM EDT

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 looked...

First CRISPR study inside the body to start in US

Jul. 25, 2019 12:08 PM EDT

Patients are about to be enrolled in the first study to test a gene-editing technique known as CRISPR inside the body to try to cure an inherited form of blindness. People with the disease have normal eyes but lack a gene that converts light into signals to the brain that enable sight. The experimental treatment...
