أظهرت دراسة سريرية واسعة أن تناول فيتامينات متعددة يوميًا قد يبطئ الشيخوخة البيولوجية لدى كبار السن، مع تأثير يعادل تقليل العمر البيولوجي بنحو أربعة أشهر بعد عامين. واستفاد أكثر الأشخاص الذين كان عمرهم البيولوجي أعلى من عمرهم الزمني. وتشير النتائج إلى إمكانية استخدام مكمل غذائي بسيط لتعزيز الصحة أثناء التقدم في العمر.
A daily multivitamin may help slow biological aging, according to researchers studying older adults in a large clinical trial. After two years, participants taking multivitamins showed slower aging in several DNA-based “epigenetic clocks,” with the effect equal to about four months less biological aging. People who started out biologically older than their actual age appeared to benefit the most.
The findings hint that a simple supplement could play a role in healthier aging.

A groundbreaking superconducting X-ray spectrometer has begun operation at BESSY II, giving Europe its first TES-based system and boosting photon detection efficiency by up to 1,000 times. The advance enables scientists to explore atomically thin materials, nanostructures, and ultra-dilute samples with remarkable speed and sensitivity.

A new international study finds that middle-aged Americans are lonelier, more depressed, and experiencing worse memory and health than earlier generations. Researchers say growing financial strain, weaker social supports, and chronic stress may explain why the U.S. is falling behind other wealthy nations.

A groundbreaking new connectome maps every neural connection in an adult fruit fly’s central nervous system, creating an unprecedented view of how the brain and body work together. The findings suggest that complex behaviors emerge from distributed local circuits rather than a single central controller, offering new clues about intelligence, movement, and brain function.
