Cassini data has revealed a surprising twist in Saturn’s magnetic shield: the planet’s rapid rotation appears to drag a key opening in its magnetosphere far toward the afternoon side instead of keeping it near noon, as happens on Earth。 The finding confirms that giant planets like Saturn operate under a fundamentally different magnetic regime, wher
Deep underground, bacteria may be capable of doing something remarkable: trapping toxic uranium before it spreads。 When researchers fed microbes in uranium-contaminated mine water with glycerol, about 95% of the dissolved uranium disappeared within 130 days。 The bacteria helped convert it into an unusually stable uranium compound that had rarely be
More than 60,000 years ago, humans in southern Africa were engraving ostrich eggshells with intricate geometric patterns that appear far more organized than previously realized。 Researchers found recurring grids, parallel lines, right angles, and repeated shapes, suggesting the designs followed deliberate rules rather than being improvised。 The eng
Stress may literally scramble the brain’s internal GPS。 Researchers found that cortisol, a hormone released during stress, made people significantly worse at navigating a virtual environment and disrupted the precise activity of grid cells, specialized brain cells that help us understand where we are in space。 When landmarks were missing, this navi
A ten-month Antarctic experiment found that astronauts may struggle not only with loneliness but also with spending too much time around the same people。 Frequent contact was linked to greater tension and mistrust, while the crew increasingly divided into cultural and language-based groups
Metal-rich asteroids could one day become hardware stores for Mars, supplying the materials needed to build and repair a growing colony。 A new analysis shows that carefully selected asteroids may be reachable with current spacecraft technology。 Some could even provide the ingredients for making rocket fuel in space, dramatically reducing the burden
A total solar eclipse will plunge parts of Europe into darkness on August 12, 2026, with Spain offering some of the best views。 ESA will livestream the spectacle from the Javalambre Observatory, combining telescope feeds, drone footage, and expert commentary。 At 20:31 CEST, the observatory will experience 1 minute and 21 seconds of totality, reveal
A 240-million-year-old reptile discovered in Brazil is revealing what evolution looked like just before the rise of dinosaurs and crocodiles。 The small predator had unusually positioned legs that may have allowed it to move more efficiently than many earlier reptiles。 Its close relatives were previously known mostly from other continents, suggestin
Scientists have discovered incredibly tiny plasma whirlpools swirling across the Sun’s surface, some just 20 kilometers wide。 These previously invisible vortices may twist magnetic fields and help build up the energy released in small solar eruptions called nanoflares。 They may also help magnetic fields spread through the Sun’s atmosphere far faste
The rise of the potato in the Andes appears to have left a lasting mark on human DNA。 Indigenous Peruvians carry exceptionally high numbers of a starch-digestion gene, likely because people with more copies gained an evolutionary advantage once potatoes became a staple food。 The change began thousands of years before European contact, providing unu
NASA engineers have found a clever way to squeeze more life out of Voyager 2, nearly half a century after it left Earth。 In an operation nicknamed the “Big Bang,” the team simultaneously shut down certain power-hungry hardware and switched to lower-power alternatives while keeping the spacecraft warm enough to survive
As data centers gobble up memory chips, other industries that need the components, including electronics companies like Apple and medical device makers, are asking for government help
Yiyang Zhuge was already an intellectual celebrity in China。 Her viral interview with Christopher Nolan made her famous in the US—and quickly turned her into a political Rorschach test
