Scientists create supercharged vitamin K that helps the brain heal itself

Scientists in Japan have created powerful new vitamin K-based compounds that may help the brain regenerate lost neurons — a breakthrough that could one day change how diseases like Alzheimer’s and Parkinson’s are treated. By combining vitamin K with components related to vitamin A, the researchers developed compounds that were about three times more effective at turning neural stem cells into neurons than natural vitamin K alone.

Women’s faces rated more attractive even by other women, study finds

‘Gender attractiveness gap’ appears across cultures and over centuries but difference fades away with ageWomen’s faces are rated as more attractive than men’s, even by other women, but the perceived gap declines with age and all but vanishes by the time people reach their 80s, researchers have said.The work appears to confirm the existence of a “gender attractiveness gap”, an observation reflected in centuries of language that present women as “the fairer sex”, “das schöne Geschlecht”, “le beau

Large Hadron Collider detects strange particle behavior that could rewrite physics

Scientists working at CERN’s Large Hadron Collider may be seeing the strongest hints yet of physics beyond the Standard Model — the decades-old theory that explains the fundamental particles and forces of the universe. By studying incredibly rare particle transformations called “penguin decays,” researchers found behavior that doesn’t fully match theoretical predictions, raising the possibility that unknown particles or forces are influencing the results.

Scientists create global treasure map pointing to hidden rare earth deposits

Scientists have created a global “treasure map” for rare earth elements by uncovering where the strange volcanic rocks that contain them are most likely to form. By combining thousands of rock samples with seismic images of Earth’s deep interior, the team discovered that these metal-rich rocks tend to appear along the ancient, thick roots of continents. These unusual rocks, once seen as geological oddities, are now incredibly important because they hold many of the materials used in smartphones,

Queenless wasp colonies explode into chaos but hidden helpers save them

When a queen wasp suddenly disappears, her colony doesn’t calmly choose a successor — it erupts into chaos. Researchers found that female wasps immediately begin battling for power, shattering the colony’s social order in a frenzy of aggression. But while some fight for the throne, others quietly become the colony’s unsung heroes, stepping up to gather food and care for the young so the society doesn’t collapse.

Deadly fungus and lung parasites are hammering wild rattlesnakes

A sweeping new study of wild snakes in the southeastern US has revealed a hidden health crisis slithering beneath the surface. Researchers found that many snakes are carrying multiple infections at once, with a dangerous fungal disease called ophidiomycosis — or snake fungal disease — emerging as one of the biggest threats. Pygmy rattlesnakes appeared especially vulnerable, frequently infected with both the fungus and a parasitic “snake lungworm.”
