A new study suggests the brain begins making decisions much earlier than scientists previously thought. Researchers found that even primary sensory regions are influenced by higher brain areas through rapid feedback loops, rather than simply passing ...

An unexpected study found that young non-smokers with healthier diets had higher rates of lung cancer, raising questions about whether pesticide exposure from conventionally grown produce could play a role. Researchers stress that the findings are .. ...

Scientists have developed a new framework that could finally apply the laws of thermodynamics to real, ever-changing black holes instead of only perfectly stable ones. The advance may improve our understanding of black hole mergers, evaporation, and ...

Researchers analyzing data from more than 214,000 people found that dementia risk factors differ widely across countries, challenging the idea of a one-size-fits-all prevention strategy. At the same time, they uncovered surprisingly consistent ...

Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in collaboration with the German Aerospace Center (DLR). In the scientific journal Physical Review Letters, they show that this ...

Researchers found that bacteria linked to gum disease may help drive the development of calcific aortic valve stenosis by triggering inflammation and calcium buildup in the heart valve. The early findings suggest that keeping gums healthy could play ...

A new study suggests spacecraft exhaust could quickly contaminate the moon's most scientifically valuable regions, potentially masking ancient clues about how life began on Earth. Researchers say future lunar missions should consider new ways to ...

Citizen scientists have helped researchers solve a long-standing mystery about how parental care evolved in harvestmen. Using photos and observations from iNaturalist, scientists more than doubled the known cases of egg-guarding behavior and ...

Researchers found that tau is essential for turning new experiences into lasting memories by helping organize the brain's memory-storing cells. The mouse study also revealed how abnormal tau may contribute to Alzheimer's by disrupting both the ...

Researchers have recreated the physics of extracting energy from a spinning black hole using a stationary device that produces synthetic ultrafast rotation. The achievement transforms a long-standing theoretical idea into a practical experiment and . ...
