Phys.org / Scientists discover a hidden RNA 'aging clock' in human sperm
Increasing paternal age has been linked to elevated health risks for the next generation, including higher risks of obesity and stillbirth. But what drives this increased risk remains unknown.
Tech Xplore / Compostable circuits could slash environmental impact of electronics
A new type of circuit board which is almost entirely biodegradable could help reduce the environmental harms of electronic waste, its inventors say.
Medical Xpress / Young people may temporarily withdraw from social media use on the day they self-harm
New research from the Institute of Psychiatry, Psychology & Neuroscience at King's College London, in partnership with YoungMinds, has examined the image-posting habits on social media of young people who self-harm. The study ...
Phys.org / ALMA reveals teenage years of new worlds
Astronomers have, for the first time, captured a detailed snapshot of planetary systems in an era long shrouded in mystery. The ALMA survey to Resolve exoKuiper belt Substructures (ARKS), using the Atacama Large Millimeter/submillimeter ...
Medical Xpress / Convoluted systems block access to GP appointments
Centrally imposed systems for booking GP appointments and the effort needed to keep them working to improve access for patients is having the opposite effect, according to new research led by the University of Southampton ...
Tech Xplore / A self-assembling shortcut to better organic solar cells
Osaka Metropolitan University scientists have created a molecule that naturally forms p/n junctions, structures that are vital for converting sunlight into electricity. Their findings offer a promising shortcut to producing ...
Medical Xpress / Vitamin B12 clues on cellular metabolism offer hope for new therapies
Vitamin B12 is long understood as a vital nutrient required for red blood cell formation and nerve function, but a new Cornell study suggests its role in human biology is far more intricate, with implications for aging, metabolism ...
Medical Xpress / Common diabetes drug fails to improve walking performance in peripheral artery disease patients
A common diabetes medication does not help people with peripheral artery disease (PAD) and without diabetes walk farther, according to results from a major U.S. clinical trial published in JAMA.
Medical Xpress / Brain activity maps challenge traditional descriptions of prefrontal cortex
For more than a century, maps of the brain have been based on how brain tissue looks under the microscope. These anatomical maps divide the brain into regions according to structural variations in the tissue. But do these ...
Phys.org / New quantum boundary discovered: Spin size determines how the Kondo effect behaves
Collective behavior is an unusual phenomenon in condensed-matter physics. When quantum spins interact together as a system, they produce unique effects not seen in individual particles. Understanding how quantum spins interact ...
Medical Xpress / Study reveals potential therapeutic target for treating glaucoma
Researchers have identified a metabolically sensitive cell subtype in the eye's drainage system which shows early signs of dysfunction in a genetic mouse model of glaucoma.
Phys.org / How cities are changing social behavior in urban animals
Sealed surfaces, artificial light and constant noise: What is part of everyday life for humans poses major challenges for other animals. A new international review conducted by researchers from Bielefeld University now reveals ...
