Phys.org / A Plan B for space? On the risks of concentrating national space power in private hands
Private companies are no longer peripheral participants in U.S. space activities. They provide key services, including launching and deploying satellites, transporting cargo and astronauts to the International Space Station, ...
Phys.org / New species of ancient mollusk found in South Korean waters
Scientists have discovered a new species of chiton, an ancient marine mollusk that has remained virtually unchanged for the last 300 million years. Chitons have an elongated oval shape with a shell composed of eight interlocking ...
Phys.org / The 'Great Texas Freeze' killed thousands of purple martins: Biologists worry recovery could take decades
Thousands of birds, including beloved purple martins, died in "The Great Texas Freeze" of 2021. A study published in Nature Ecology & Evolution led by biologists at the University of Massachusetts Amherst, reveals not only ...
Phys.org / Arabic document from 17th-century rubbish heap confirms existence of semi-legendary Nubian king
A recent study published in Azania: Archaeological Research in Africa explores new historical evidence of one of pre-colonial Dongola's earliest rulers. Previously considered semi-legendary, the discovery of a document in ...
Phys.org / Neutrons reveal magnetic signatures of chiral phonons
Physicists in China have uncovered new evidence that chiral phonons and magnons can interact strongly inside magnetic crystals. Using neutron spectroscopy, a team led by Song Bao at Nanjing University mapped magnetic signatures ...
Phys.org / Binary star population of open cluster NGC 2158 explored with Hubble
Astronomers have analyzed the images collected by the Hubble Space Telescope (HST) to investigate a galactic open cluster known as NGC 2158. Results of the study, published Feb. 25 on the arXiv pre-print server, provide essential ...
Phys.org / New LVK catalog adds 128 gravitational-wave candidates, more than doubling detections
When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves, that reverberate across space and time, over hundreds of millions and even billions of years. ...
Medical Xpress / Cancer has a unique nuclear metabolic fingerprint, researchers discover
More than 200 metabolic enzymes, many of which are normally tasked with producing energy in the mitochondria, are also found sitting directly on top of human DNA, according to a study published in Nature Communications. The ...
Tech Xplore / Carbon nanotube fiber 'textile' heaters could help industry electrify high-temperature gas heating
A cross-disciplinary team at Rice University has developed a new type of electric heating element—one that looks less like a traditional metal coil and more like a high-performance thread. In a study published in Small, ...
Tech Xplore / Tiny thermometers offer on-chip temperature monitoring for processors
The semiconductor chips driving modern-day computer processors are covered in billions of individual transistors, each of which can overheat under stress, causing steep drops in performance. To address this, a team led by ...
Phys.org / Engineers improve infrared devices using century-old materials
After decades of intense research, surprises in the realm of semiconductors—materials used in microchips to control electrical currents—are few and far between. But with a pair of published papers, materials engineers ...
Phys.org / Toxic evolution: How wasps and frogs mimic pain molecules to deter predators
Certain species of wasps and frogs share a pain and inflammation peptide similar to one found in vertebrates to help defend against predators—a discovery that contributes to a shifting view of how evolution works, say researchers. ...
