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 / 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 ...
Phys.org / From the lab to the moon: Lunar cement alternative survives 6 months on ISS and returned stronger in some tests
Building material samples from the University of Delaware spent six months mounted outside the International Space Station, where the harsh conditions of low Earth orbit tested their limits.
Phys.org / Caddisfly silk gene evolves quickly without losing adhesive power
Caddisflies are among nature's master underwater builders, capable of spinning sticky silk that they use to form protective cases and webs in freshwater streams. Scientists like the University of Utah's Russell Stewart have ...
Phys.org / Could geoengineering work to tamp down super El Niños?
With an anticipated "super" El Niño looming, a new study led by UC San Diego's Scripps Institution of Oceanography considers whether society could use a weather-altering technique as a tool to mitigate the floods, extreme ...
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 / 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 ...
Tech Xplore / AI memory bottleneck may ease as ultrathin chip stacks quadruple high-bandwidth memory density
A Korean research team has developed a technology that enables the stable stacking of more than 10 ultrathin semiconductor chips, each only one-fifth the thickness of a human hair. A research team successfully achieved an ...
Phys.org / Maize-fed animals may have helped Maya farmers solve corn's protein deficiency
Maize (corn) is a major dietary staple in Maya communities past and present because of its reliability, potential for surplus, and suitability as both food and fodder. It became so important to ancient Mesoamerican communities ...
Medical Xpress / Lung transplant dramatically improves survival for patients with terminal lung cancer, study finds
A landmark Northwestern Medicine study published in JAMA suggests lung transplantation can significantly extend survival in select patients with advanced lung cancer.
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 ...
Medical Xpress / Surgeons use teleoperated humanoid robots to perform live surgery—a world first
For the first time, two teleoperated humanoid robots have been used to complete two surgeries during a preclinical trial, researchers report in the July 8 issue of the journal Nature. The work is the result of a collaboration ...
