A large study found that people with impaired kidneys tend to have higher Alzheimer's biomarkers, yet they don't face a higher overall risk of dementia. For those who already have elevated biomarkers, kidney problems may speed up when symptoms appear ...

Cedars-Sinai scientists have created a new experimental drug called TY1 that helps the body repair damaged DNA and restore injured tissue. The discovery came from studying tiny molecular messages released by heart cells that naturally support healing ...

Kyushu University scientists have achieved a major leap in fuel cell technology by enabling efficient proton transport at just 300°C. Their scandium-doped oxide materials create a wide, soft pathway that lets protons move rapidly without clogging .. ...

Researchers engineered a strained germanium layer on silicon that allows charge to move faster than in any silicon-compatible material to date. This record mobility could lead to chips that run cooler, faster, and with dramatically lower energy ...

Researchers found that people with anxiety disorders consistently show lower choline levels in key brain regions that regulate thinking and emotions. This biochemical difference may help explain why the brain reacts more intensely to stress in ...

Researchers studying people with major psychiatric disorders found that drinking up to four cups of coffee a day is associated with longer telomeres. This suggests a potential slowing of biological aging by about five years. However, drinking five or ...

Penn State researchers created seven new high-entropy oxides by removing oxygen during synthesis, enabling metals that normally destabilize to form rock-salt ceramics. Machine learning helped identify promising compositions, and advanced imaging ...

A network of powerful ground-based telescopes captured rare starspot-crossing events on TOI-3884b, revealing cooler patches on the star's surface and rapid changes tied to its rotation. By combining multicolor transit observations with months of high ...

Fresh evidence suggests early Earth wasn't locked under a rigid stagnant lid but was already experiencing intense subduction. Ancient melt inclusions and advanced simulations point to continents forming far earlier than expected. The findings ...

Experiments reveal that pond frogs can eat highly venomous hornets without suffering noticeable damage, even after repeated stings. Most frogs successfully consumed hornets, including the notorious Asian giant hornet. This unusual resilience suggests ...
