A recent study has revealed that males of some of humanity’s earliest ancestors …

A child’s skeleton, found nearly a century ago in Skhul Cave on Mount Carmel in Israel, has taken on new meaning after a modern re-analysis. A fresh look at the skull and jaw, dated to roughly 140,000 years ago, suggests that the remains show a blend of Homo sapiens and Neanderthal traits. The authors say this specimen is …

Here’s what you’ll learn when you read this story: A molecular biogerontology professor believes we’ve only started to move toward holding off aging, and that humans will eventually have the potential to live for 1,000 to 20,000 years. Technology not yet created would be key to extreme longevity, as we would need to be able to eliminate aging at the …

If Salmonella poisoning conjures thoughts of being deathly ill with an upset stomach from undercooked chicken or eggs, you’re not alone. Another type – Salmonella Dublin – is primarily associated with cattle and can cause more severe illness in people. Doctors see more bloodstream infections, longer hospital stays, and a higher risk of severe outcomes when this dangerous bacteria infects …

The view of Great Salt Lake’s North Arm from Gunnison Island, which has long served as a nesting ground for pelicans. Credit: Brian Maffly, University of Utah For thousands of years, Utah’s Great Salt Lake reflected only natural shifts in climate and water flow. But fresh sediment analyses show that in just two centuries, human activity forced the lake into …

Some of the first human settlers in the Americas carried more than primitive skills and tools, they also brought a small but powerful genetic variant called MUC19. That gene fragment, inherited from an extinct hominin called Denisovans, appears to have helped early people cope with new diseases, foods, and landscapes. In a new study, a team of scientists …

A dangerous superbug commonly found in cattle can jump to humans, and researchers warn that infections may soon become untreatable.  A team from Penn State University discovered that Salmonella Dublin has become increasingly resistant to antibiotics and is spreading to humans through contaminated beef, milk, or cheese, or through direct contact with infected cows. Researchers studied 2,150 Salmonella Dublin strains from …

Prehistoric paintings found deep inside a perilously inaccessible cave in the French Pyrenees reveal how ancient hunter-gatherers risked their necks to conduct ritual activities in the bowels of the Earth. Known as Etxeberri Cave, the site is considered one of the most challenging caverns to have been explored by Palaeolithic humans, and may have been decorated as part of a …

Facebook Tweet Email Link Modern humans are evolutionary survivors, thriving generation after generation while our ancient relatives died out. Now, new research into our brain chemistry suggests that an enzyme unique to Homo sapiens may have made us more efficient water seekers than our closest extinct relatives. About 600,000 years ago, modern humans genetically diverged from the lineage that produced …
