The Indian and Pacific oceans have been climatically linked for centuries, but scientists say that connection is now breaking down in an exceptional way. Ancient climate records suggest volcanoes disrupted the relationship in the past, while today .. ...

Scientists have engineered yeast to turn PET plastic and agricultural waste into ingredients for protein-rich, 3D-printed cookies called µBites. Developed partly for NASA's Deep Space Food Challenge, the system can produce proteins, fats, vitamins, ...

Ancient rocks from Western Australia suggest water was reaching deep inside Earth more than three billion years ago, long before modern plate tectonics may have fully developed. Researchers propose that water-rich pieces of crust periodically sank .. ...

Long-lived bats appear to combine powerful immune defenses with unusual strategies for eliminating damaged cells, potentially helping them avoid cancer and disease for decades. Researchers hope these genetic tricks could eventually reveal new ways to ...

A feather discovered inside 66-million-year-old fossilized dinosaur poop may help explain why modern birds survived the asteroid catastrophe. The extinct bird it came from had more primitive insulating feathers, suggesting superior plumage may have . ...

Britain's wasps have become mysteriously scarce this summer, and scientists suspect an unusual combination of temperature swings, heatwaves, and food shortages may be responsible. Even the wasps that remain appear unusually small, potentially ...

Scientists have directly observed how two negatively charged DNA molecules can pair up despite normally repelling each other. Positively charged metal ions appear to bridge the gap, helping matching DNA helices align groove for groove like a ...

Scientists have used DNA from living descendants to identify four more members of the doomed Franklin expedition, including Harry Peglar, whose identity had remained uncertain for 166 years. The findings offer new clues about the sailors who survived ...

While clearing debris to protect ancient Egyptian tombs from flash floods, researchers near Luxor stumbled upon an unknown 3,000-year-old tomb. Its remarkably preserved paintings depict an official named Paser, his wife, religious scenes, and ...
