Phys.org / Orbit overload could devastate astronomy if 1.7 million proposed satellites brighten night sky
A new European Southern Observatory (ESO) study has found that current proposals to launch more than 1.7 million satellites into orbit, including extremely bright ones, would have "devastating consequences for astronomy." ...
Phys.org / Martian dust storms may generate atmospheric electrical conditions that could impact future missions
A new study by a doctoral researcher at The University of Alabama in Huntsville (UAH), part of The University of Alabama System, suggests global dust storms on Mars may organize the Martian atmosphere into regions favorable ...
Phys.org / Were Clovis foragers in Late Pleistocene North America big-game hunters, or just big-game scavengers?
There are currently 15 well-documented Late Pleistocene localities in North America in which Clovis points are found associated with proboscidean remains (of mammoth, mastodon and gomphothere). Archaeologists routinely assume ...
Phys.org / Climate resilience of brown bears over 175,000 years revealed in 3D analyses of their jaws
European brown bears are masters of survival: These animals have weathered Pleistocene climate fluctuations and survived the cycles of ice ages and interglacial periods to the present day. Zoologists have now investigated ...
Phys.org / New bioelectronic microdevices enable remote cell stimulation using ultrasound
The Universitat Autònoma de Barcelona (UAB) and the Institute of Microelectronics of Barcelona (IMB-CNM-CSIC) have developed a new generation of wireless piezoelectric microdevices capable of electrically stimulating living ...
Phys.org / Crystal-design principle reveals how competing molecular forces control structure, color and phase transitions
Organic molecular crystals can respond to external stimuli such as heat, light, and mechanical force, making them attractive candidates for next-generation functional materials. However, predicting how multiple intermolecular ...
Phys.org / Webb reveals merger scars in galaxies that stopped forming stars 9 billion years ago
Research has shed new light on why some distant galaxies suddenly stop forming stars. An international team led by astronomers at the University of Nottingham has used the James Webb Space Telescope to study a large sample ...
Phys.org / Tooth fossil analysis suggests 'brawn before bite' in early Asian mammals
An analysis of fossil teeth from mammals that lived in China following the most recent major mass extinction suggests size came before both shape and function as diets diversified.
Phys.org / From fields to space farming, new tool detects crop drought stress before it's visible
When it comes to drought stress, timing can be the difference between saving a crop and losing it, whether in a greenhouse or in the high-stakes environment of future space missions. In a recent study published in Plant Phenomics, ...
Phys.org / Black-box optimization weather intervention method supports future disaster mitigation
In recent years, the frequency of weather-related natural disasters—cyclones, torrential rains, floods—has increased as a consequence of global warming. These disasters cause billions of dollars in damage and losses every ...
Phys.org / Can AI plan for heat emergencies better than simple rules? It depends
The thermometer reads 95°F (35°C) in Brooklyn, and vulnerable individuals need information to take appropriate action. New York City officials must gather facts quickly to provide updates on cooling centers, power outages ...
Phys.org / Himalayan pangolin emerges as distinct species, confirmed with DNA from 19th-century specimen
The pangolin is a midsize mammal found only in Africa and Asia. The pangolins' scales make them unique, but these scales have become their undoing. Pangolins are poached for their scales, making them the most highly trafficked ...
