Medical Xpress / Automated CT scan analysis could fast-track clinical assessments
A research team has developed a versatile machine learning model that could one day greatly expand what medical scans can tell us about disease. Scientists used their tool, named Merlin, to assess 3D abdominal computed tomography ...
Medical Xpress / Researchers link Parkinson's-related protein to faster Alzheimer's progression in women
Alzheimer's-related brain changes progressed up to 20 times faster in women who also had abnormal levels of a Parkinson's-related protein, according to a Mayo Clinic study published in JAMA Network Open. The same pattern ...
Phys.org / Nitrous oxide, a product of fertilizer use, may harm some soil bacteria
Plant growth is supported by millions of tiny soil microbes competing and cooperating with each other as they perform important roles at the plant root, including improving access to nutrients and protecting against pathogens. ...
Medical Xpress / Stem cells from human baby teeth show promise for treating cerebral palsy
A Japanese research team has demonstrated in rat experiments that stem cells from human primary tooth pulp may help treat chronic-phase cerebral palsy. "This is the first animal study to show that stem cell treatment works ...
Phys.org / Arrowhead marks found in Central Asia could prove the existence of Homo sapiens 80,000 years ago
Unretouched triangular microlithic projectile points have been identified from their impact traces in the oldest occupation layers of the Obi-Rakhmat site in Uzbekistan, dating to 80,000 years ago. Their size corresponds ...
Phys.org / How an underground fungal map of the world's oldest, slowest-growing rainforest trees can boost Earth's resilience
The temperate rainforests of the Chilean Coast Range are home to a spectacular array of life: iridescent blue lizards, tiny wild cats called kodkods, and curly vines of waxy red bellflowers. Towering over this biodiversity ...
Phys.org / A fanged frog long thought to be one species is revealing itself to be several
When a new species is discovered, it's tempting to imagine an adventure novel, said Chan Kin Onn of Michigan State University. "Most people have this image of an intrepid explorer braving an isolated mountain or some other ...
Medical Xpress / Ultra-processed foods in preschool years associated with behavioral difficulties in childhood
A team led by researchers at the University of Toronto has found an association between ultra-processed foods in early childhood, and behavioral and emotional development. Specifically, the team found that higher ultra-processed ...
Phys.org / Wildlife imaging shows that AI models aren't as smart as we think
Using AI to identify wildlife reveals a potential "transferability crisis," researchers say. Marketing for AI imaging systems often suggests that models can easily tackle novel scenarios across ecosystems and settings, much ...
Phys.org / New 4D-STEM method isolates atomic structures from clustered nanocrystals
Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new way to determine atomic structures from nanocrystals previously considered unusable, a breakthrough that could ...
Phys.org / Ancient plant-eater with a twisted jaw and sideways-facing teeth was a 'living fossil' in its own time
In a dry riverbed in Brazil, in a dense forest near the Amazon, a team of paleontologists found a fossilized jawbone from an ancient animal. Over the course of their fieldwork, they found eight similar bones, each around ...
Phys.org / Radiocarbon dating rewrites angiosperm trees' lifespan records worldwide
For decades, scientists have relied on tree rings to estimate how long trees can live. But new research suggests that this widely used method may have been underestimating the lifespan of many flowering trees—sometimes ...
