Phys.org / Manganese risk in groundwater affects 200 million people, study shows
Manganese is an essential trace element. However, in excessive concentrations, the metal can cause health problems. Two Eawag researchers have now produced a global risk map for manganese in groundwater. Half of the world's ...
Phys.org / Indigenous peoples in the Amazon face massive cultural and ecological loss due to climate change
The Amazon region, Earth's most important ecosystem, is home to more than 400 Indigenous groups that use thousands of rainforest plant species. They pass on their knowledge of the flora primarily through oral tradition, usually ...
Phys.org / The language of play: Hyenas use facial expressions and vocalizations to de-escalate
Scientists observed spotted hyenas (Crocuta crocuta) playing in the wild and found that their precise, sophisticated communication is on par with that of many primate species. Hyenas play and romp with one another at all ...
Phys.org / Space sensor could spot hidden nuclear weapons in orbit with 99% accuracy
In 2024, a U.S. government official warned that Russia could be developing a new satellite designed to carry nuclear weapons into space. The statement followed the launch of a suspicious Russian satellite into low-Earth orbit ...
Phys.org / Block-by-block AI maps uncover real urban air temperatures across 380 U.S. cities
Cities are often described as "heat islands," with media reports warning that some neighborhoods can be 20° F (7° C) hotter than others. But those temperatures are often based on satellite data rather than the conditions ...
Medical Xpress / Alcohol drives opposite brain circuit changes in amyloid and tau Alzheimer's models
Alcohol use has been associated with an increased risk of cognitive decline and dementia. But new research from Texas A&M University's Naresh K. Vashisht College of Medicine at Texas A&M Health suggests the relationship between ...
Phys.org / How approaching sounds can warp your perception of time
Everyone's perception of time is unique. It is a subjective experience shaped by factors such as age, emotions, memory and environmental contexts. And it may also be influenced by background noise, as scientists have demonstrated ...
Phys.org / Satellites are transforming biodiversity monitoring for global nature targets, but major gaps remain
A new scientific review outlines how satellites and other remote sensing technologies are increasingly shaping how biodiversity and ecosystem health can be monitored at scale—offering new opportunities for countries reporting ...
Science X / Your brain expects each face to move its own way, and notices when a smile breaks that rule
Imagine meeting someone new whose smile feels just a bit wrong. You might think, "this smile is too fast (or slow, or crooked)," even if the movement itself is common. How could your brain sense this subtle "offness" from ...
Phys.org / Unraveling a long-standing solar mystery: The extreme thinness of the sun's tachocline layer
Researchers are closer to unraveling a longstanding solar mystery surrounding the extreme thinness of the sun's tachocline layer of strong shearing motion—a region believed to be critical for creating the violent eruptions ...
Tech Xplore / A soft exoskeleton could restore hand function in people with motor impairments
Recent technological advances have opened valuable possibilities for supporting people with motor impairments or who are recovering from injuries to the brain, spinal cord or nerves. Millions of people worldwide currently ...
