The fire department at NASA’s Ames Research Center in California’s Silicon Valley will perform training on the Moffett Federal Airfield beginning Tuesday, Sept. 8 through Friday, …
Embedded platinum channels bring nanoscale spin-based thermoelectric conversion to bulk materials
A joint research team from NIMS and the University of Tokyo has developed a new composite in which three-dimensional nano-interfaces are distributed throughout the material by coa…
Food and water stations for wild birds are contributing to spread of deadly diseases, study finds
Feeding stations providing food and water for wild birds are contributing to the spread of disease-causing parasites among farmland birds, researchers have said, with birds three …
Virus-like particles enable gene activity tracking over time in the same cells
In recent years, scientists have developed methods to measure a cell's transcriptome, or all the RNA produced by a cell, to study the cell's identity and genetic activity. However…
Trekkies honor 'Star Trek's' 60th birthday with fan events, special screenings, and a world record Vulcan salute
Beam into these stellar celebrations to mark the sci-fi franchise's historic anniversary this Labor Day Weekend!
Sound waves and water droplets transform paper waste into higher-value chemical compound
Researchers at the University of Illinois Urbana-Champaign have developed a fast, simple way to turn lignin, a plentiful plant-based byproduct of the papermaking industry, into po…
Underlying mechanism of Atg2-mediated lipid transfer in autophagy identified
Autophagy is an intracellular degradation mechanism in eukaryotes. The autophagosome, which encloses damaged or excess cellular material for degradation, is constructed from lipid…
Particle shape and size predict asteroid strength, revealing Bennu's surface is 50 times weaker than ground coffee
In a new Nature Communications study, researchers developed a universal scaling framework for the strength of granular asteroids, showing that their tensile strength can be predic…
From pets to zoos: How students perceive animal husbandry
Animals fulfill a wide range of roles in human society. They provide food, contribute to scientific research, live alongside people as companion animals, and play important roles …
Archaea as 'flexitarians': Ammonia-oxidizing microbes also feed on amino acids
Symbiotic ammonia-oxidizing archaea in marine sponges are not strict specialists but true "flexitarians." A team led by microbiologists Bettina Glasl and Katharina Kitzinger from …
Venus is becoming a thinner crescent — and that's when it finally starts making sense
Venus is sinking into the sunset as it catches up with Earth — and a small telescope now reveals something the naked eye never can: another planet going through phases.
Turbulent times for star formation in Stephan's Quintet
Star formation in galaxies is closely linked to molecular gas. In the distant past, when galaxy interactions were more common, these encounters compressed molecular gas, causing d…
Alcohol-related cancer deaths in US have more than doubled over three decades
Study finds just one drink per day could raise risk of disease with impacts extending far beyond liver cancerAlcohol-related cancer deaths in the US have more than doubled over th…
'Soft crosslinking' strategy makes brittle, glassy plastics tougher
Glassy polymers are those whose chains become immobilized below their glass transition temperature. The immobilized chains make them hard and stiff but also brittle, causing them …
Bats show promise as a form of biological pest control in South African macadamia plantations
Labor-intensive harvesting and complex processing make macadamias among the most expensive nuts in the world. This makes it all the more important to protect the trees from pests.

NASA will host a virtual webinar at 2 p.m. EDT on Friday, Oct. 2, titled “The RS-25 Engine and the Future of Artemis Missions: An Accessible Webinar for the Blind and Low-Vision C…
Ultrafast electrons and lasers reveal unexpectedly strong radiation signals in common semiconductors
Detecting radiation is key to technologies ranging from particle accelerators and scientific instruments to medical imaging and security screening. But current detectors must ofte…
Capturing localized protein and metabolic information from a single tissue section
Revealing how proteins and end products of biological activity (metabolites) change within specific tissue functional units during development or in response to environmental fact…
Betelgeuse's atmosphere is becoming spotty and asymmetric—and a nearby companion could be shaping the pattern
For the first time since its dramatic dimming in 2020, a team of astronomers has observed the inner atmosphere of Betelgeuse using the Atacama Large Millimeter Array (ALMA). Led b…
Stars forge and deliver the elements that make up your body — and scientists may finally know how
Scientists are close to understanding how stars forge the elements that comprise our planet, bodies and pretty much everything else around us, and how they explode to distribute t…
Ultrafast sample spinning improves protein structural data by dizzying proportions
Researchers have been elucidating the structures of complex molecules for more than 100 years using a variety of techniques. Some molecular structures, however, are more difficult…
Since the 1980s, climate change has increasingly altered European bumblebee habitats
Global biodiversity loss is occurring at a rapid pace, driven by multiple human-caused factors, including overexploitation, pollution, invasive species and climate change. Despite…
