Bumble bees battling invasive Argentine ants may win individual fights but ultimately lose valuable foraging time, putting pressure on colonies already strained by habitat loss, disease, and pesticides. New research shows bees often avoid ant ...

Researchers have uncovered surprising evidence that anxiety may be controlled not by neurons but by two dueling groups of immune cells inside the brain. These microglia act like biological pedals--one pushing anxiety forward and the other holding it ...

Scientists studying aging found that sensory inputs like touch and smell can cancel out the lifespan-boosting effects of dietary restriction by suppressing the key longevity gene fmo-2. When overactivated, the gene makes worms oddly indifferent to .. ...

Smoking, vaping, or using both products significantly increases the likelihood of developing prediabetes and diabetes, and the risk is even higher among Hispanic, Black, and low-income groups. Researchers found that vaping alone raises prediabetes .. ...

Footprints preserved on ancient dunes show Neanderthals actively navigating, hunting, and living along Portugal's coastline. Their behavior and diet suggest a far more adaptable and socially complex population than once assumed.

Scientists have developed a new way to build rare-earth crystals that boosts quantum coherence to tens of milliseconds. This leap could extend quantum communication distances from city blocks to entire continents. The method uses atom-by-atom ...

Simulations reveal that Jupiter's rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and chemistry of chondrite meteorites found on Earth. .. ...

Arctic sea ice is disappearing fast, and scientists have turned to an unexpected cosmic clue--space dust--to uncover how ice has changed over tens of thousands of years. By tracking helium-3-bearing dust trapped (or blocked) by ancient ice, ...

Researchers discovered that living horsetails act like natural distillation towers, producing bizarre oxygen isotope signatures more extreme than anything previously recorded on Earth--sometimes resembling meteorite water. By tracing these isotopic . ...

Researchers have designed a smart drug that hunts down and breaks a little-known RNA that cancer cells depend on. The drug recognizes a unique fold in the RNA and triggers the cell to destroy it. Tests showed that removing this RNA slows cancer ...
