Ancient Chinese Rock Art Survived 2,000 Years Because of Human Blood
Researchers analyzing paint from the Huashan cliff murals in southern China identified human blood proteins as the binder that kept the iron-red figures vivid for over two millennia. The blood, combined with hematite and lime, triggered a mineralization process that made the paint progressively more stone-like — and harder to destroy — over time.
Why Rivers Are Running Dry Decades Before Hydrology Models Predicted
Three interacting mechanisms — atmospheric moisture demand, severed groundwater buffers, and soil moisture debt — are draining rivers like the Rio Grande and Colorado decades ahead of what hydrological models forecast, forcing researchers to revise core water cycle assumptions.
Deep-Sea Creatures That Survive Without Sunlight, Oxygen, or Food
More than 60 percent of Earth's surface is covered by deep ocean, and the strange creatures living there have evolved physiology so extreme it overturns basic assumptions about what animals need to survive.
How to Fake a Fossil: Palaeontologists Reveal the Surprisingly Simple Method
The toolkit for faking a fossil overlaps almost entirely with legitimate preparation techniques, and palaeontologists who study fraud say the most dangerous fakes are composites of real bones — meaning chemical tests pass while the joins go undetected.
Ancient Egyptian Princesses Were Trained Archers — Their Bones Prove It
New bioarchaeological research on royal mummies from the Dahshur necropolis shows that ancient Egyptian princesses, including Princess Ita, developed skeletal signatures consistent with habitual bow training — and functional weapons buried alongside them reinforce the finding.
NASA’s Roman Telescope Could Detect 400 Rogue Planets — Each Visible for Hours
NASA's Nancy Grace Roman Space Telescope could detect roughly 400 Earth-mass rogue planets drifting starless through the Milky Way, using gravitational microlensing events that last only hours — though researchers caution the forecast carries enormous uncertainty.Load More
