Phys.org / Betelgeuse's elusive companion star: Siwarha's 'wake' detected
Using new observations from NASA's Hubble Space Telescope and ground-based observatories, astronomers have tracked the influence of a recently discovered companion star, Siwarha, on the gas around Betelgeuse. The research, ...
Phys.org / Climate messaging sways minds, not wallets, regardless of political party
In a study involving more than 13,000 participants in the U.S., several messaging strategies were shown to move the needle—albeit slightly—in attempts to strengthen pro-environmental attitudes and behaviors regarding ...
Phys.org / Biological pumps: How zooplankton are transporting microplastics to the ocean depths
A new study has, for the first time, recorded and measured just how fast microplastics move through the gut passage of a key zooplankton species in real time—and used those measurements to estimate how much plastic these ...
Medical Xpress / Restoring mitochondria shows promise for treating chronic nerve pain
For millions living with nerve pain, even a light touch can feel unbearable. Scientists have long suspected that damaged nerve cells falter because their energy factories known as mitochondria don't function properly.
Phys.org / The US used to be really dirty: Environmental cleanup laws have made a huge difference
Growing up in the 1970s, I took for granted the trash piles along the highway, tires washed up on beaches, and smog fouling city air. The famed "Crying Indian" commercial of 1971 became a symbol of widespread environmental ...
Phys.org / EPA says it will propose drinking water limit for perchlorate, but only because court ordered it
The Environmental Protection Agency on Monday said it would propose a drinking water limit for perchlorate, a harmful chemical in rockets and other explosives, but also said doing so wouldn't significantly benefit public ...
Phys.org / Taste buds: From flavor explosions to muted meals—why our taste changes as we age
Ever bitten into a hot pie, yelped "Hothothot!" then had your taste buds go on strike for the next week? Taste buds are a sensitive bunch.
Phys.org / Early hominins from Morocco reveal an African lineage near the root of Homo sapiens
An international research team reports the analysis of new hominin fossils from the site of Thomas Quarry I (Casablanca, Morocco). The fossils are very securely dated to 773,000 +/- 4,000 years ago, thanks to a high-resolution ...
Phys.org / The Milky Way's black hole is hiding an explosive past, evidence suggests
Our galaxy's supermassive black hole is famous for being one of the dimmest in the universe. Evidence from a new space telescope shows that might not always have been the case.
Phys.org / Marine geoscientists link warming with ancient ocean 'salty blob'
Climate change has many culprits, from agriculture to transportation to energy production. Now, add another: the deep ocean salty blob.
Phys.org / Supernova remnant video from NASA's Chandra is decades in making
A new video shows the evolution of Kepler's Supernova Remnant using data from NASA's Chandra X-ray Observatory captured over more than two and a half decades.
Tech Xplore / Breaking performance barriers of all-solid-state batteries through pure structural design
Batteries are an essential technology in modern society, powering smartphones and electric vehicles, yet they face limitations such as fire explosion risks and high costs. While all-solid-state batteries have garnered attention ...
