The bones of a teenage hunter-gatherer who died more than 7,000 years ago on the Indonesian island of Sulawesi tell the story of a previously unknown group of humans.
This distinct human lineage has never been found anywhere else in the world, according to new research.
The study published Wednesday in the journal Nature
New research details the evolutionary history of rhinoceroses, exposing a surprising lack of genetic diversity throughout their long history. Given that all living species of rhinos are currently endangered and facing their own genetic bottlenecks, the new research could improve conservation efforts.
Woolly mammoths were icons of the Ice Age. Starting 700,000 years ago to just 4,000 years ago, they trundled across the chilly steppe of Eurasia and North America. As ancient glaciers expanded across the Northern Hemisphere, these beasts survived the rapidly cooling temperatures with cold-resistant traits, a characteristic they came by not through evolution, as earlier thought. Woolly mammoths, a new Nature study finds, inherited the traits that made them so successful from a mammoth species closer to a million years old.
An analysis of coelacanth DNA suggests its genome has experienced some significant changes in recent evolutionary history, potentially dispelling the popular image of these iconic fish as being “living fossils.”
Around five years ago, when the gene editing technology CRISPR was still new, Kamel Khalili started work on ways to use the system to treat and cure HIV. Khalili, director of the Comprehensive NeuroAIDS Center at the Lewis Katz School of Medicine at Temple University, showed then that CRISPR could effectively clear HIV in both cells and in animals.

Northern Europeans who speak Uralic languages, such as Estonian and Finnish, can thank ancient migrating Siberian populations for their dialects, according to a fascinating new study that combined genetics, archaeology, and linguistics.

When she was eight years old, Jo Cameron broke her arm and didn’t tell anyone for days; it just wasn’t bothering her. In the six-odd decades since, she has sustained numerous injuries and felt barely any pain. Sometimes, she accidentally leans on her stove, only to notice when she smells burning flesh.
