Phys.org / Chang'e mission samples reveal how exogenous organic matter evolves on the moon
Elements essential to life, such as carbon, nitrogen, oxygen, phosphorus, and sulfur, were "delivered" to Earth and the moon during the early stages of the solar system via asteroids and comets impacting their surfaces. These ...
Phys.org / Highway widening may be heating cities faster; here's what could curb it
U.S. cities are rapidly becoming urban heat islands, where these cities are significantly warmer than their surrounding area. Vast expanses of asphalt and concrete trap heat, while large, densely packed buildings disrupt ...
Phys.org / AI chips could get faster with 30-nanometer embedded memory that cuts data shuttling
When we watch videos or ask AI questions, enormous amounts of data are constantly moving inside computers. In particular, data centers that support AI must process and transfer vast amounts of data at very high speeds. However, ...
Phys.org / Using menstrual blood-derived particles to treat osteoarthritis
New research by an interdisciplinary team in Lithuania has revealed a promising and unconventional approach to cartilage regeneration. Using extracellular vesicles derived from menstrual blood stromal cells, the researchers ...
Phys.org / Unlocking Earth's 4.5-billion-year secret: The case of the missing lead
Geoscientists have long relied on different forms of lead to understand Earth's geological history and how it was created over billions of years. However, there is a mystery that has been puzzling scientists for decades: ...
Phys.org / Scientists discover f-block metals yield new oxygen-binding chemistry
Iron and oxygen bind together throughout the body. Most famously, iron binds dioxygen, or two oxygens paired with each other, in hemoglobin that transports oxygen through blood. But iron-oxo compounds, as they're called, ...
Phys.org / How bromoform wrecks ozone: Ultrafast 'roaming' step captured in 150 femtoseconds
The halomethane compound bromoform (CHBr3) has devastating effects on the ozone layer. In the upper layers of the atmosphere, bromoform reacts with UV radiation, releasing bromine molecules which destroy ozone molecules. ...
Phys.org / After reaching speeds of 10,657 meters per second, Artemis II hurtles home for make-or-break splashdown
The Artemis II astronauts conducted a historic lunar flyby, gathered invaluable data and took in unprecedented moon views, but one of the most crucial moments of their 10-day mission is still to come: Friday's splashdown.
Phys.org / Unexpected predator: Jellyfish shown to hunt polychaete worms
Most polychaete species spend their lives in burrows in the seabed. However, adult individuals of two species, Alitta succinea and Platynereis dumerilii, leave their burrows to spawn during warm summer nights around the full ...
Phys.org / Climate change is outpacing evolution. Scientists are using DNA to catch up
Evolution works over millennia. Climate change is moving far faster. That mismatch is killing some of the planet's most vital ecosystems, from California's towering redwoods to the seagrass meadows along its coast, both of ...
Phys.org / Unraveling the complexities of the Borna disease virus 1
Cases of Borna disease virus 1 (BoDV-1) are extremely rare in humans, but in those who develop disease, the outcome is severe, almost always resulting in fatal encephalitis or inflammation in the brain. This zoonotic virus ...
Phys.org / Why warmer Caribbean waters could mean slower hurricanes and worse flooding
Rapid ocean warming is likely to make tropical cyclone rainfall more intense and longer lasting, increasing flood risks in parts of the North Atlantic region. A new study led by Newcastle University using satellite data shows ...
