Phys.org / Small but mighty dung beetles take a big bite out of farm methane
Dung beetles are quietly performing a vital climate change mitigation service for Australia's livestock sector, slashing methane emissions from cattle manure by 85%, a new Southern Cross University study has found.
Phys.org / New computational imaging method cuts X-ray dose while preserving high resolution
Researchers have shown that it's possible to take clear, high-resolution X-ray images using very little radiation. With more development, the new approach could eventually make medical X-ray diagnostics less risky and more ...
Phys.org / Roadless rule helps protect clean drinking water for 25 million Americans, new study shows
Approximately 90% of the U.S. population relies on public water systems. A significant portion of the water supplying those systems comes from forested lands, which means policies affecting forests also affect water access.
Phys.org / Low-altitude flights reveal Amazon methane emissions far above climate model estimates
Methane (CH4) is a potent greenhouse gas whose concentration in the atmosphere has risen sharply in recent decades. Wetlands are the largest natural source of methane to the atmosphere, but large uncertainties remain about ...
Medical Xpress / New multiple sclerosis criteria could reveal disease before symptoms appear
The international guidelines for diagnosing multiple sclerosis (MS), called the McDonald criteria, underwent their most significant overhaul in a decade in 2024. The internationally recognized framework is used to diagnose ...
Medical Xpress / Study shows where women live can shape heart health for decades
Women who live in disadvantaged neighborhoods face worse heart health and experience faster declines as they approach menopause, according to a long-term study led by the Harvard Pilgrim Health Care Institute.
Medical Xpress / Amyloid-clearing treatment may curb tau buildup for years in Alzheimer's brain
An analysis of the brain of a deceased Alzheimer's disease (AD) clinical trial participant found that regions where an anti-amyloid therapy successfully cleared amyloid plaques showed little to no evidence of tau tangles, ...
Medical Xpress / Sleep disorders don't just exhaust you, they change your brain
Sleep disorders may do more than leave people feeling tired. New research from Florida International University shows that sleep disorders are associated with structural changes in brain regions involved in attention, motivation ...
Phys.org / Ancient Roman farm women made wine, oil and profits. Historians dismissed them as 'housekeepers'
Female farm managers are hidden in plain sight in ancient Roman texts, mentioned in laws, literature and grave inscriptions across five centuries. Modern historians have generally assumed they were housekeepers, in charge ...
Medical Xpress / Can magnetic fields help fight Parkinson's disease?
An international team has succeeded in using a magnetic field to target structures deep within the brain. The researchers injected magnetic nanoplatelets into the relevant region. By doing so, they succeeded in treating movement ...
Medical Xpress / Roasted and browned: How gut bacteria break down heated foods
Crusty bread, fried meat and roasted coffee owe their characteristic taste and browning to chemical reactions that occur when foods are heated. In the so-called Maillard reaction, amino acids—the building blocks of proteins—react ...
Phys.org / Scientists find hidden individuality in viral infections
An international team of researchers developed a new way to uncover hidden differences in how viruses infect and destroy individual microbial cells—solving a biological puzzle that has persisted for more than 80 years.
