Phys.org / Could a recently detected ultra-high-energy neutrino be linked to new physics?
Neutrinos are extremely lightweight and electrically neutral particles that rarely interact with ordinary matter. Due to these rare interactions, neutrinos can travel across space almost entirely unaffected, carrying information ...
Phys.org / Climate change is slowing Earth's spin at unprecedented rate compared to past 3.6 million years
Climate change is lengthening our days because rising sea levels slow Earth's rotation. Researchers from the University of Vienna and ETH Zurich now show that the current increase in day length—1.33 milliseconds per century—is ...
Phys.org / War threatens Gulf's dugongs, turtles and birds
From sea turtles to birds and the gentle dugong, the Persian Gulf's diverse but fragile marine life is threatened by the bombs and oil of the war in the Middle East.
Phys.org / Physicists break longstanding high-temperature superconductivity record at ambient pressure
Researchers from the Texas Center for Superconductivity (TcSUH) and the department of physics at the University of Houston have broken the temperature record for superconductivity at ambient pressure—a breakthrough that ...
Phys.org / Ryugu asteroid samples contain all DNA and RNA building blocks, bolstering origin-of-life theories
All the essential ingredients to make the DNA and RNA underpinning life on Earth have been discovered in samples collected from the asteroid Ryugu, scientists said Monday.
Phys.org / Dinos hatched eggs less efficiently than modern birds, researchers show
What do we really know about how oviraptors—bird-like but flightless dinosaurs—hatched their eggs? Did they use environmental heat, like crocodiles, or body heat from an adult, like birds? In a new Frontiers in Ecology ...
Phys.org / Palm-sized superconducting magnet achieves 42 tesla, rivaling the world's biggest
When we think of powerful magnets used in particle accelerators or for NMR (nuclear magnetic resonance), we often envision bulky machines, sometimes the size of buildings. But in an extraordinary breakthrough for physics, ...
Phys.org / Extremely rare second-generation star discovered inside ancient relic dwarf galaxy
Discovered in the Pictor II dwarf galaxy, star PicII-503 has an extreme deficiency in iron—less than 1/40,000th of the sun. This signature makes it the clearest example of a star within a primordial system that preserves ...
Phys.org / Bull sharks form social relationships with specific 'friends,' research reveals
Sharks are often viewed as solitary, but a new study—carried out on the Shark Reef Marine Reserve in Fiji—has found that rather than mixing at random, bull sharks have "active social preferences" and choose their social ...
Phys.org / The first modern rocket launched 100 years ago, beginning a century of both innovations and challenges for spaceflight
Apollo 11 first landed astronauts on the moon in 1969, but the journey to the lunar surface actually began 43 years before, in snowy Massachusetts.
Phys.org / ISS study identifies thresholds for muscle atrophy and fiber changes in reduced gravity
It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in near-zero gravity (microgravity) environments. However, the gravity threshold needed to maintain sufficient ...
Phys.org / Pi Day: From rockets to cancer research, here's how the number pi is embedded in our lives
Math nerds and dessert enthusiasts unite to celebrate Pi Day every March 14, the date that represents the first three digits of the mathematical constant pi.
