Phys.org / Rare Roman paint 'recipe' uncovered in Cartagena murals makes smart use of costly cinnabar
Roman painters commissioned at the end of the 1st century to decorate the walls of the Domus of Salvius in present-day Cartagena could hardly have imagined that their technical expertise would still attract attention twenty ...
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 / Bacteria from bumblebees can produce vitamin B₂ in soya drinks
Researchers at DTU have developed a new method that can reduce the time needed to find new bacteria for fermentation. They have now identified a bacterium that can be used both for acidification and to increase the vitamin ...
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 / 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 / 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 / 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 / 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 / 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 / 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 / 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 ...
