For Modern Humans, Neanderthals Were a Lifeline

We might not have survived without them, genomes reveal

(Newser) - Modern humans didn't physically overcome Neanderthals to emerge as the dominant human species. Instead, Homo sapiens mated with Neanderthals, and new research suggests it was only due to interbreeding between the two species that Homo sapiens—now with inherited genes that helped them adapt to life in Eurasia—found...

Shark That Can Live 400 Years Reveals Its Secret

Greenland shark genome shows duplicated genes involved in DNA repair

(Newser) - The Greenland shark is the world's longest-living vertebrate, or animal with a backbone, capable of living a mind-bending 400 years. Now, with the mapping of the shark's genome, the biggest of any shark sequenced to date, researchers say they've unlocked potential secrets to the animal's longevity...

Blue Whales Carry Surprising Levels of Another Species' DNA

North Atlantic blue whales receiving fin whale DNA through mating with hybrid offspring

(Newser) - The blue whale population has started to recover from the devastation brought by commercial whaling in the early 20th century. But the world's largest ever animal isn't quite the same. In analyzing the genomes of Balaenoptera musculus musculus—the "most endangered" of four subspecies of blue whale,...

Scientists Find an Ancient Syphilis Relative in Brazil

Research suggests the bacterium has been around for millennia

(Newser) - People who lived with painful mouth and skin sores on the south coast of Brazil some 2,000 years ago carried the oldest known evidence of a syphilis relative.

Humans Mated Outside Our Species 3 Times

Second instance of human-Denisovan interbreeding discovered

(Newser) - Ancient humans weren't against knocking boots with other species: We know they had sex with Neanderthals . We also know they mated with the mysterious Denisovans, as some Australasians (those from Papua New Guinea in particular) have 5% Denisovan DNA. But a "breakthrough" study shows the interbreeding wasn't...

Canaanites Weren't Annihilated by Ancient Israelites After All

Researchers say they lived on to become the ancestors of today's Lebanese

(Newser) - The Bible suggests the Canaanites were wiped out by the ancient Israelites, but a new study says otherwise, claiming the people survived and went on to be the ancestors of those who today live in Lebanon, ScienceDaily reports. Per a study in the American Journal of Human Genetics , researchers from...

Scientists unlock genome for foodie favorite quinoa

(Newser) - It has been hailed as a super food, a nutrient-packed , gluten-free dish that even carb counters can get behind. But could quinoa feed a hungry planet? That's the hope behind a new effort by scientists who've unlocked the humble grain's genome. "Quinoa has great potential to...

Morning Person or Night Owl? Your Genes May Decide

Biology may be influencing if you stay up all night or wake up with the sun

(Newser) - You may be naturally disposed toward being a morning person or a night owl—and scientists are now saying that may have a true biological basis that's hard to fight, the Guardian reports. Per a study published Tuesday in Nature Communications , researchers under the direction of 23andMe lead scientist...

Scientist Tackles 'Last Major Disease We Don't Know Anything About'

Whitney Dafoe no longer walks, talks, or eats, and is fed intravenously

(Newser) - Whitney Dafoe packed a lot in his first quarter-century of life. The son of renowned scientist Ronald Davis, the head of the Genome Technology Center at Stanford University, was an award-winning photographer who traveled the world and worked on Obama’s 2008 campaign. Now 31 and diagnosed with systemic exertion...

Study: DNA Test Can Predict Whether You're Gay

Potential for misuse troubles lead scientist, who's just left the lab

(Newser) - UCLA scientists think they've developed the first test that can accurately predict whether a man is gay based on his DNA, and all it takes is a swab of saliva, reports New Scientist . The researchers examined 400,000 epigenetic tags—"chemicals that latch onto DNA and help turn...

Test Can Detect Every Virus to Afflict Humans, Animals

Even uncommon viruses and ones present in low levels: scientists

Genome Reveals Secrets of Last Mammoths

Low genetic variation perhaps led to decline on Wrangel Island

(Newser) - The last of the woolly mammoths in Siberia died out about 10,000 years ago, but a smaller number living on Wrangel Island, off the coast of what is now Russia, managed to stick around for another 6,000 years. Researchers set out to investigate the two groups and the...

Google's Big New Project: Autism Research

Company aids in sequencing thousands of genomes

(Newser) - To learn more about the genetics behind autism, researchers are planning to sequence the genomes of thousands of people—and they've enlisted a partner who knows a thing or two about sifting through scads of data. Using its Genomics tool, Google will host on its servers and index the...

Easter Islanders Not as Isolated as Thought

Genetic data suggests travel to and from South America 20-plus generations ago
