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 piezoe...
The universe is less uniform than we thought—cosmology may need a radical rethink
Modern cosmology rests on a simple assumption: If we look on large enough scales, matter should be distributed evenly, with no preferred direction within the co...
Mobile learning output expanded rapidly from 2017 to 2026, analysis of 2,500 papers shows
A bibliometric analysis of mobile learning research published between 2017 and 2026 shows a sharp expansion in output. There was a big surge between 2020 and 20...
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...
13,000 tons of space junk clutters Earth orbit. Here's how it could be cleaned up
Seventy years ago, Earth had only one satellite: the moon. Now it has more than 15,000—about 10,000 of which are owned by Elon Musk's SpaceX. The world's first...
Prickly starfish and urchins are decimating Australia's reefs. But we could find ways to protect them
Australia is home to some of the world's most beautiful reefs. This includes the lush Great Southern Reef, which wraps around Australia's southern coastline, an...
XMM-Newton and Chandra help revise distance to Milky Way's outer spiral arms
The European Space Agency's XMM-Newton and NASA's Chandra X-ray space telescopes have spotted the aftermath of three bright explosions echoing through the outer...
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...
ESA outlines high-tech lander instruments for 2050 Enceladus
Saturn's moon Enceladus has become a prime solar system target for astrobiologists. This is because the small moon, which is just over 10% the diameter of Earth...
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 brig...
How a giant planet survived its star's death, then migrated inward
When astronomers discovered a giant planet orbiting a dead star in 2020, they wondered how it survived its star's violent demise. Now, observations from NASA's...
Algae may have launched coral reefs by hijacking coral cells, genetic experiments suggest
The reefs scattered throughout the tropics arose only after algae took up full-time residence in coral cells, supplying corals with abundant food and enabling t...
