You and Your Doppleganger Share More Than Looks
Study shows that unrelated look-alikes also share genes and even behaviors
- Studies of twins are common. Studies of unrelated people who could pass for twins, not so much. But in Cell Reports , researchers dug deep into the phenomenon of dopplegangers—look-a-likes who are aren't actually related—and discovered that they share far more than superficial appearances, reports Science Alert . An...

In Phenomenon Seen Across Species, the Ladies Have It
Female mammals typically live longer, likely owing to genetics
- 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%...

3 Cheetahs, 2 Cubs, One 'Big Breakthrough'
Birth via surrogacy allows for greater genetic diversity
- 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
- 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
- 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...

Big Breakthrough Could Mean Pig Organs in Humans
Scientists who've created genetically modified piglets say perhaps in 2 years
- Pig organs have long been eyed as transplant options for humans, as the organs are about the same size and pigs are plentiful, but it's been challenging to overcome the human immune system's possible rejection of such organs. Now, in what one medical expert tells the
