A remote island between Australia and Antarctica is showing signs of a dramatic climate transformation. Scientists found storms over Macquarie Island now unleash much heavier rainfall than they did decades ago, soaking ecosystems and altering fragile ...

UC Davis researchers created brand-new psychedelic-like compounds by shining UV light on amino acid-based molecules. These compounds activated key serotonin receptors tied to brain plasticity and mental health benefits, but surprisingly did not cause ...

A huge long-term study found that drinking two to three cups of coffee a day was linked to a much lower risk of dementia, especially before age 75. Researchers say caffeine may help keep brain cells active while reducing inflammation and harmful ...

For nearly 100 years, reinforced rubber has powered everything from car tires to airplanes, yet scientists never fully understood why adding tiny particles of carbon black made rubber so incredibly strong. Now, researchers at the University of South ...

A medieval monk may have beaten Edmond Halley to one of astronomy's greatest discoveries by nearly 700 years. Researchers say Eilmer of Malmesbury recognized that the blazing comet seen in 1066 was the same one he had witnessed in 989. At the time, . ...

Humans may have returned to Britain far earlier than scientists once believed -- not long after the last ice sheet began retreating. New evidence suggests people were already moving into the British Isles around 15,200 years ago, tracking herds of .. ...

Scientists in Japan have developed a new way to instantly detect elusive quantum "W states," a major milestone for quantum technology. The breakthrough could help unlock faster quantum communication, teleportation, and powerful new computing systems.

A new quantum-inspired algorithm has cracked a problem so massive that conventional supercomputers struggle to even approach it. Researchers used the method to simulate extraordinarily complex quantum materials known as quasicrystals, opening the ...

Researchers have uncovered unexpectedly high levels of silicone-based pollutants called methylsiloxanes floating through the atmosphere across cities, rural regions, and even forests. Much of the pollution appears to come from vehicle emissions, ...

Cacti may look like slow, stubborn desert survivors, but they're actually evolving at lightning speed. Scientists studying more than 750 cactus species discovered that what really drives the explosion of new cactus species isn't flower size or ...
