Phys.org / Grasslands are vanishing nearly four times faster than forests, global study finds
Along with forests, grasslands and wetlands are also being converted to cropland and pasture at an increasing rate around the world—often for livestock farming and the export of agricultural products. An international team ...
Phys.org / Carbon-based catalyst can use sunlight to degrade PFAS
An international team of scientists led by the University of Bath has developed a new catalyst—a substance that speeds up chemical reactions—that uses sunlight to break down so-called "forever chemicals" prevalent in ...
Medical Xpress / Blood test boosts Alzheimer's diagnosis accuracy to 94.5%, clinical study shows
A protein lurking around in the blood can help with the accurate diagnosis of Alzheimer's disease. In a recent study, researchers from Spain investigated how blood-based biomarkers, such as a protein called p-tau217, affect ...
Phys.org / ALMA explores giant molecular clouds in nearby galaxy NGC 1387
An international team of astronomers has employed the Atacama Large Millimeter/submillimeter Array (ALMA) to investigate molecular gas in a nearby galaxy known as NGC 1387. Results of the observational campaign, published ...
Phys.org / Human activity is influencing the behavior of Germany's wildcats
A research team led by Dr. Chris Baumann and Dr. Dorothée Drucker from the Senckenberg Center for Human Evolution and Paleoenvironment at the University of Tübingen has found that the European wildcat is increasingly using ...
Medical Xpress / More than eco-anxiety: Study exposes emotional fallout of climate crisis for youth
A few years ago, researcher Maya Gislason's young child came home from school with her crayon drawing of Earth in 2020 and 2050. "The first was blue and green; the second was a planet on fire," she says. "Her question to ...
Medical Xpress / Women show greater tau buildup and faster cognitive decline than men in Alzheimer's
Tau proteins act like the brain's maintenance crew, helping maintain the structure and proper function of brain cells. In neurodegenerative diseases such as Alzheimer's, the tau proteins can form tangles that disrupt normal ...
Phys.org / Peanut waste can be turned into high-quality futuristic graphene
Researchers at UNSW have discovered a new way to make graphene, a remarkable "wonder material," using just discarded peanut shells. The development opens the door to cheaper, more sustainable electronics and energy storage ...
Phys.org / 40,000-year-old Stone Age symbols may have paved the way for writing, long before Mesopotamia
Over 40,000 years ago, our early ancestors were already carving signs into tools and sculptures. According to a new analysis by linguist Christian Bentz at Saarland University and archaeologist Ewa Dutkiewicz at the Museum ...
Phys.org / Using high-energy sparks to degrade pollutants without generating waste
A study published in the Chemical Engineering Journal proposes a new approach to environmental remediation of pharmaceutical pollutants in water flows. This approach is based on a phenomenon known as "sparks," which refers ...
Medical Xpress / Male sex, older age predict poor outcomes in seniors with HFmrEF/HFpEF
Considerable sex disparities are reported in elderly patients with heart failure with mildly reduced or preserved ejection fraction (HFmrEF/HFpEF), with male sex and older age predicting poor outcomes, according to a study ...
Phys.org / Urine tests confirm alcohol consumption in wild African chimpanzees
Aleksey Maro knows far more than he cares to know about the urination habits of chimpanzees. But if you want to measure the alcohol intake of chimps in a Ugandan rain forest, where a breathalyzer is impractical, collecting ...
