You and Your Doppleganger Share More Than Looks

Study shows that unrelated look-alikes also share genes and even behaviors

(Newser) - Studies of twins are common. Studies of unrelated people who could pass for twins, not so much.

DNA Slavery Study Yields Surprises

More enslaved people came to the US from Nigeria than previously thought, researchers say

(Newser) - Using historical records has been the most traditional way to shed light on the dark stain of slavery in the United States. Now, per new research that the Scientist calls "the largest DNA study to examine African ancestry in the Americas," gene analysis is helping put more pieces...

In Phenomenon Seen Across Species, the Ladies Have It

Female mammals typically live longer, likely owing to genetics

(Newser) - It's not just in human populations that females tend to live longer than males. The same trend has been seen in mammals such as elephants, lions, and orcas, according to a new study. Indeed, demographic data for 134 populations of 101 mammalian species shows females outlive males in 60%...

For Gene Editing, a 'New Frontier'

If deemed safe, scientists hope for widespread use of CRISPR procedure inside patients' bodies

(Newser) - "We literally have the potential to take people who are essentially blind and make them see." Those are the attention-grabbing words of Charles Albright, the chief scientific officer at Editas Medicine, which is sponsoring a study to wield DNA technology in a novel way: edit genes using the...

3 Cheetahs, 2 Cubs, One 'Big Breakthrough'

Birth via surrogacy allows for greater genetic diversity

(Newser) - Ohio has welcomed two new scientific marvels—the first ever cheetah cubs born via in vitro fertilization. Cheetahs are a vulnerable species, with only 7,500 left in the wild. They also have low genetic diversity owing to a mass die-off about 10,000 years ago. That's made breeding...

Do Humans Have a 'Gay Gene?' Big New Study Thinks Not

Sexual orientation is instead a complex stew of genetics and environment, say researchers

(Newser) - Humans do not have a "gay gene" that determines their sexual orientation, according to the largest study (by far) ever conducted on the issue. Researchers studied the genomes of 470,000 people, hunting for a pattern to explain human sexuality, reports Live Science . They found five genetic markers deemed...

Landmark Gene-Editing Work May Help Restore Vision

Researchers will use CRISPR technology to try to help patients with rare disease

(Newser) - 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, per the AP . People with the disease have normal eyes but lack a gene that converts light into signals to...

Woman Feels No Pain, Didn't Realize It Until Age 65

Jo Cameron has been through several operations and childbirth without painkillers
