Signs of injury to the brain’s white matter called white matter hyperintensities, as seen on brain scans, may be tied more strongly to vascular risk factors, brain shrinkage, and other markers of dementia in former tackle football players than in those who did not play football. Signs of injury to the brain’s white matter called …

Acute spinal cord injury (SCI) patients lose body weight and muscle mass, despite being on a high-calorie diet while in the intensive care unit. Their muscle wasting is substantial and extends beyond what can explained by inactivity or denervation (loss of nerve supply) alone. Research sheds new light and decodes early muscle loss after SCI …

Research reveals a steady increase in the number of people at risk from tropical cyclones and the number of days per year these potentially catastrophic storms threaten health and livelihoods. The findings could help relief agencies, development banks, and other organizations plan more effective strategies for mitigating extreme weather impacts. Research reveals a steady increase …

Researchers have identified a previously unrecognized class of antibodies — immune system proteins that protect against disease — that appear capable of neutralizing multiple forms of flu virus. The findings could contribute to development of more broadly protective flu vaccines. Researchers have identified a previously unrecognized class of antibodies — immune system proteins that protect …

New research shows that tears from women contain chemicals that block aggression in men. The study finds that sniffing tears leads to reduced brain activity related to aggression, which results is less aggressive behavior.

Researchers have identified a new iguana species, Wang’s garden lizard (Calotes wangi), in southern China and northern Vietnam. This species, part of the Calotes versicolor complex, was discovered through extensive surveys conducted from 2009 to 2022. Measuring less than 9 cm with an orange tongue, it inhabits subtropical and tropical forests, thriving in various landscapes …

Protein-splitting enzymes play an important role in many physiological processes. Such proteases are generally present in an inactive state, only becoming activated under certain conditions. Some are linked to diseases like infections or cancer, making it important to have methods that can selectively detect active proteases. Scientists have introduced a new class of protease-activity sensors: …
