Phys.org / Water simulation of famous quantum effect reveals unexpected wave patterns
In the quirky quantum world, particles can be affected by forces that they never directly encounter. A classic example is the Aharonov–Bohm (AB) effect, where electrons are affected by a magnetic field, despite not passing ...
Medical Xpress / CDC report on COVID vaccine blocked from publication
A federal report pointing out the benefits of COVID-19 vaccines may never be released, according to multiple people familiar with the decision.
Phys.org / When humidity changes, so do the colors of sweat bees
Nature is a riot of color. In the animal kingdom, many species, from insects to cephalopods, use their permanent color or change it for communication, camouflage, and thermoregulation. While this type of reversible shift ...
Phys.org / The moon might be more prone to fires
Engineers love a good practical challenge, especially when it comes to spaceflight. But there's one particular challenge facing the crewed missions of the near future that scares mission planners above almost all others—fire. ...
Phys.org / Cold fronts in nearby galaxy group may redistribute metals, Chandra and GMRT data reveal
Astronomers from South Africa and India have analyzed archival data from the Chandra X-ray Observatory and Giant Metrewave Radio Telescope (GMRT) regarding a nearby small galaxy group known as IC 1262. Results of the new ...
Medical Xpress / HEPA air purifiers may boost brain power in adults over 40
Using an in-home HEPA purifier for one month spurs a small but significant improvement in brain function in adults age 40 and older. That's the result of a new study we co-authored in the journal Scientific Reports.
Phys.org / Soundwaves settle debate about elusive quantum particle
It was a head-spinning discovery. In 2018, researchers in Japan claimed to find concrete evidence of an elusive particle, a Majorana fermion, in a quantum spin liquid called ruthenium trichloride. Majoranas are highly sought-after ...
Phys.org / A philosopher's serpent: New grass-green pitviper discovered in China's Giant Panda National Park
Draped in a uniform coat of vibrant grass-green and possessing eyes that shimmer like amber, a newly discovered pitviper is the latest hidden jewel to be found in the misty mountains of western Sichuan, China.
Phys.org / They promised climate action for years, but what these meat and dairy giants were really selling was something else
The meat and dairy industry accounts for 57% of total global food production emissions and at least 16.5% of all global greenhouse gas emissions. But the vast majority of environmental claims from the animal agricultural ...
Phys.org / Milk's hidden carbon bill is bigger than advertised as damaged grass and soils drive emissions higher
Livestock farming causes a significant share of the world's greenhouse gas emissions. According to a new study, the carbon footprint of milk may be considerably larger than commonly calculated when carbon released from the ...
Medical Xpress / Mobile app-based coaching can support healthy weight gain in pregnancy, new study finds
Obesity during pregnancy has been steadily increasing worldwide. In the United States, over 60% of pregnant individuals enter pregnancy overweight or obese, and more than half go on to exceed recommended gestational weight ...
Phys.org / Engineered soil bacterial protein kills colorectal cancer cells by targeting their mitochondria
Researchers at Umeå University have turned a protein from soil bacteria into a potential new weapon against colorectal cancer. Their study published in Cell Death Discovery shows how an engineered bacterial protein can trigger ...
