Ancient surgeons may have practiced dangerous skull-opening procedures on cows before operating on people.
A previously excavated cow skull from a roughly 5,400- to 5,000-year-old settlement in France contains a surgically created hole on the right side, a new study finds. No signs of bone healing, which start several days after an injury, appear around the opening. One or more people...
Pathogen detectors built into plastic patches could someday spare you food poisoning.
Carlos Filipe, a chemical engineer at McMaster University in Hamilton, Canada, and colleagues have developed a new kind of flexible film that’s coated in molecules that glow when they touch E. coli cells. This type of sensor also glows in the presence of molecules secreted by E. coli, so the material...
With the promise and pitfalls of umbilical cord blood samples in mind, how should parents decide whether to put their baby’s blood on ice, either for their own family’s future use or as a donation for the greater good? It’s a tricky calculation, one that changes based on a family’s risk threshold, dreams for the future and, of course, money.

Every autumn, a quiet mountain pass in the Swiss Alps turns into an insect superhighway. For a couple of months, the air thickens as millions of migrating flies, moths and butterflies make their way through a narrow opening in the mountains. For Myles Menz, it’s a front-row seat to one of the greatest movements in the animal kingdom.
Menz, an ecologist at the University of Bern in...
Stephen Hawking, a black hole whisperer who divined the secrets of the universe’s most inscrutable objects, left a legacy of cosmological puzzles sparked by his work, and inspired a generation of scientists who grew up reading his books.
Upon Hawking’s death on March 14 at age 76, his most famous discovery — that black holes aren’t entirely black, but emit faint...

Biological invasion via Suez
The Red Sea is invading the Mediterranean.… So far about 140 life-forms, mostly animal and mostly invertebrate, have crossed the Isthmus of Suez.… It is possible that this … will result in the loss of a few native fish and invertebrate populations to stiff competition from the newcomers. — Science News, March 30, 1968Update
