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 / SNIPE bacterial defense system shreds phage DNA before infection can begin
What if the Trojan horse had been pulled to pieces, revealing the ruse and fending off the invasion, just as it entered the gates of Troy? That's an apt description of a newly characterized bacterial defense system that chops ...
Phys.org / Camera-tagged Adélie penguins caught eating sea snails in East Antarctica
There are many poorly understood links in the food web, often referred to as trophic relationships. Out in East Antarctica, a previously unconfirmed link between sea snails and Adélie penguins might reveal more than meets ...
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 / Subaru Telescope sheds light on Jupiter Trojan asteroids' color mystery
Observations conducted with the Subaru Telescope and its first-generation wide-field camera, Suprime-Cam, have revealed new insights into the relationship between the color and size of Jupiter Trojan asteroids.
Phys.org / Underwater architects: Nest-building in cichlids reveals more than hardwired instinct
We associate nests with shelter, warmth, and a safe retreat—and usually picture a bird's nest made out of twigs, grass and feathers. Yet many other animals take advantage of such refuges, with nests being built by a diversity ...
Phys.org / Tropical trees are more neighborly than trees further from the equator, study finds
Tropical trees are better neighbors than trees in temperate forests, according to a study published in the journal Nature by researchers from 29 different institutions including the Smithsonian Tropical Research Institute ...
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 / 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 / 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 / Nicotine's last biosynthesis steps mapped in wild tobacco, ending a long mystery
Nicotine, a potent insecticidal alkaloid unique to the nightshade family, has been employed in agriculture as a pesticide since 1690. It also has therapeutic potential for neurological disorders such as Alzheimer's disease, ...
