Medical Xpress / Your address, ancestry and gut may be steering aging in ways medicine has barely begun to map
Researchers at the Stanford School of Medicine have found that ethnicity and geography may influence human molecular makeup—from metabolism and immunity to gut microbiota and biological aging. The findings, published in Cell, ...
Phys.org / A child's environment may shape how their brain solves problems
For decades, researchers have documented an achievement gap between children from higher- and lower-income families. On average, children with more resources perform better in school and on cognitive tests.
Phys.org / Why ocean warming experiments may be making misleading predictions
Accurate experiments on how ocean warming affects marine life are vital to ensure we can best prepare for the future, protect our food sources, and help safeguard ocean ecosystems. But some of these experiments may miss how ...
Medical Xpress / Engineered brain 'bypass' that rewires specific circuits could boost resilience to stress
Broken or disrupted circuits in the brain contribute to many neurological disorders. A new custom-built biological "wire" developed at Duke University School of Medicine points the way toward a new treatment approach—bypassing ...
Phys.org / Buried in dark waters, viruses reshape one of Earth's largest carbon systems
Viruses play a far more active role in Earth's carbon cycle than previously understood, according to new research that reveals how they infect and control microbes responsible for carbon production in some of the planet's ...
Phys.org / NASA's Psyche spacecraft buzzing Mars on its way to a rare metal asteroid
A NASA spacecraft chasing a rare metal asteroid swings past Mars this week for a gravity boost, snapping thousands of pictures as practice for the main encounter in 2029.
Phys.org / The first domesticated horses: 6,000 years of a complex story
Horses were being ridden, worked, and traded long before anyone thought it possible. New research pushes back the accepted timeline of human use of horses by centuries, showing that humans used horses in organized ways as ...
Medical Xpress / Caffeine may influence the way the brain responds to touch
Many people begin each day with a steaming cup of joe to shake off the morning fog and jump-start their brain. Whether it's a shot of espresso or a frothy latte, that caffeine hit is famous for boosting alertness. However, ...
Medical Xpress / Is 'yo‑yo dieting' really harmful? New analysis challenges longstanding assumptions about weight cycling
Weight loss followed by weight regain, commonly known as "yo-yo dieting" or weight cycling, is often portrayed as harmful, even more damaging than remaining overweight. But a new comprehensive analysis published in The Lancet ...
Medical Xpress / Genes give neurons a 'GPS' to form the brain's neural circuits, scientists show
How complex neural circuits are genetically designed and wired is a fundamental question in neuroscience. Scientists have shown for the first time that genes encode a "wiring map" that guides neurons to connect with the correct ...
Phys.org / Satellite launch pollution is rapidly accumulating in the upper atmosphere
The potent pollution from so-called megaconstellation satellite systems launched en masse into space since 2019 will account for nearly half (42%) of the total climate impact of space sector pollution by the end of the decade, ...
Phys.org / Radio telescopes confirm 3.3-million-light-year halo in unusually quiet galaxy cluster
Astronomers have employed the upgraded Giant Metrewave Radio Telescope (uGMRT) and the MeerKAT radio telescope to observe a galaxy cluster known as RXCJ0232–4420. Results of the new observations, published April 29 on the ...
