Phys.org / Fast charging can cause irreversible lithium migration in solid-state batteries
Solid-state batteries are often viewed as a promising path toward safer and more powerful energy storage. However, one key question has remained difficult to answer: How does lithium actually move inside the solid materials ...
Phys.org / Brazil deforestation hits new low in Amazon
Deforestation in the Brazilian Amazon fell to its lowest level in a decade in the first half of the year, according to official figures released Friday.
Phys.org / Much of Earth's 'space dust' may come from unidentified near-Earth asteroids
Like a shelf in an old house, the Earth collects a lot of dust from its surroundings. This "space dust" is mostly made up of micrometeorites that survive atmospheric entry and provides researchers with a cheap and easy way ...
Tech Xplore / Small aquatic robots that assemble into reconfigurable structures on the water
Most people think of the waterfront as the edge of the city. A team of MIT researchers sees it as a dynamic, Lego-like construction site. Their new system, called "FloatForm," is a swarm of small square robotic boats that ...
Phys.org / High-status Iron Age burials reveal early links to Roman Empire
A large cemetery containing the lavishly adorned remains of unidentified high-status individuals dating from around 2,000 years ago has been uncovered by archaeologists from Archaeology South-East (UCL Institute of Archaeology). ...
Phys.org / Sensors detect California cliff collapses hours to days before failure, report says
Following a four-year study, scientists at UC San Diego's Scripps Institution of Oceanography released a new report to determine whether an early warning system could detect a landslide before it happens. The "California ...
Tech Xplore / New pellet-making method points to safer, more predictable high-explosive manufacturing
For decades, manufacturing plastic-bonded high explosives, or PBXs, has relied on legacy processes like slurry coating. In this method, explosive crystals are mixed with a binder, a polymer that helps hold the material together, ...
Tech Xplore / Perovskite triple-junction solar cells reach 27.3% efficiency with record 770-hour stability
Perovskite semiconductors efficiently convert sunlight into electrical energy; they are also inexpensive and extremely lightweight. A team at HZB has developed a triple-junction solar cell comprising different perovskite ...
Phys.org / Chemists capture structure of the elusive borylnitrene trapped in a crystal using X-ray
Nitrenes are the ghosts of synthetic chemistry, formed in an instant and gone just as quickly, rearranging into something entirely different. These highly reactive intermediates are widely used in synthesis, yet remain notoriously ...
Medical Xpress / Video games might modestly sharpen your memory and other cognitive skills, review suggests
Because video games are a regular part of many people's everyday lives, researchers have spent a lot of time trying to determine whether they are beneficial or detrimental to brain health. A new study, published in Acta Psychologica, ...
Phys.org / Seagrass meadows could help nourish millions, new study finds
Seagrass meadows play a largely overlooked role in providing nutrition for coastal communities, a new study published in Cell Reports Sustainability has found. The research, led by scientists at Project Seagrass and Stockholm ...
Phys.org / 'Cosmic wallflowers' may hold the key to the origin of globular clusters
Astronomers using computer simulations have investigated whether a class of star clusters nicknamed "cosmic wallflowers" could be the long-sought ancestors of the globular clusters we see orbiting galaxies today. Their paper, ...
