A famous "oldest octopus" fossil has been exposed as a case of mistaken identity. Advanced imaging revealed hidden teeth showing it was actually related to a nautilus, not an octopus. The confusion came from decay that altered its shape before ...

Scientists at Cornell University may be closing in on the long-sought "holy grail" of male contraception: a safe, reversible, nonhormonal method that completely halts sperm production. In a breakthrough mouse study, researchers used a compound called ...

Vitamin D levels in midlife may play a bigger role in long-term brain health than previously thought. In a study following nearly 800 people over 16 years, those with higher vitamin D levels in their 30s and 40s had lower levels of tau protein later ...

A single week of intensive meditation and mind-body practices led to measurable changes across the brain and body. Researchers observed improved brain efficiency, boosted immune signaling, and increased natural pain relief chemicals in participants' ...

A surprising new study reveals that what you eat could play a powerful role in fighting cholera, a deadly diarrheal disease. Researchers found that diets rich in certain proteins--especially casein from dairy and wheat gluten--can dramatically reduce ...

A remarkable fossil discovery in southwest China is rewriting the story of how complex animal life began, showing that many key animal groups appeared millions of years earlier than scientists once believed. Dating back over 540 million years, the .. ...

A newly discovered group of tarantulas is so bizarre that scientists had to invent a whole new genus--Satyrex--to describe them. With unusually long mating appendages and fierce, hissing defenses, these spiders are as strange as they are intimidating ...

Scientists have uncovered a powerful new clue in the mystery of brain aging: a single protein called FTL1. In aging mice, higher levels of this protein weakened connections between brain cells and led to memory decline. But when researchers reduced . ...

Scientists have created an artificial saliva using a sugarcane protein that can protect teeth and fight bacteria. The key ingredient, CANECPI-5, binds directly to enamel, forming a shield against acids that cause decay. Early tests show it works even ...

Modern food systems may look stable on the surface, but they are increasingly dependent on digital systems that can quietly become a major point of failure. Today, food must be "recognized" by databases and automated platforms to be transported, sold ...
