Phys.org / Cosmologists collaborate to sharpen measurements of the Hubble constant
Drawing together leading experts from across the field, an international collaboration of cosmologists has created a unified approach for measuring the value of the Hubble constant. Published in Astronomy & Astrophysics, ...
Phys.org / Gravity from positivity: Single massive spin-3/2 particle makes gravity logically inevitable, study claims
Researchers at IPhT (CEA, CNRS) and the Universitat Autònoma de Barcelona have shown that gravity—and with it, supersymmetry—emerge as logical necessities whenever a massive spin-3/2 particle exists in nature. Two principles ...
Phys.org / Ytterbium atomic clock could open a new window on fundamental physics
For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ytterbium to create a new type of atomic clock that is both highly precise and extremely sensitive to ...
Phys.org / Underground lab clears crucial hurdle for dark matter hunt
Australia's bid to detect elusive dark matter has taken a major step forward, with new research confirming that cosmic radiation levels deep inside the Stawell Underground Physics Laboratory (SUPL) are low enough to support ...
Phys.org / Ghostly particles: Dark radiation may have masqueraded as neutrinos
New research suggests that neutrinos in the early universe may have transformed into a previously unknown form of radiation. A study from Washington University in St. Louis offers a new way to explain certain puzzling observations ...
Phys.org / Engineered tobacco plant can produce five psychedelics, including psilocybin and DMT
Compounds in psychedelic drugs like DMT, psilocybin, and psilocin are naturally produced in certain plants, fungi, and animals, and have a long history of use in spiritual and therapeutic contexts. Now, a considerable amount ...
Phys.org / New disk-shaped catalyst turns carbon dioxide into methanol at lower temperatures
Low-temperature CO2 hydrogenation might have sounded almost paradoxical until a recent study made it possible. Researchers have designed new catalysts that can transform the greenhouse gas into methanol at temperatures ranging ...
Phys.org / New evidence challenges assumptions of mass feasting at ancient Mongolian burial mounds
Khirigsuurs are Late Bronze Age monuments found across Mongolia and parts of southern Siberia. They are typically thought to be burial monuments or ritual spaces, consisting of a burial mound surrounded by satellite features ...
Phys.org / Spectacular fossil treasure trove pushes back origins of complex animals
A newly discovered fossil site in southwest China has transformed our understanding of how complex animal life emerged on Earth, revealing that many key animal groups had already evolved before the start of the Cambrian Period. ...
Phys.org / New miniature marsupial frog found in Peru carries eggs in a back pouch
Scientists have discovered a new species of miniature marsupial frog in the Peruvian Amazon that carries its young in a natural pouch on its back, a research institute reported Wednesday.
Phys.org / Early data from Vera C. Rubin Observatory reveals over 11,000 new asteroids
Using preliminary data from the Vera C. Rubin Observatory, scientists have discovered over 11,000 new asteroids. The data were confirmed by the International Astronomical Union's Minor Planet Center (MPC), making this the ...
Phys.org / Quantum entanglement between electrons and ions captured at attosecond timescale
Quantum mechanics is extremely successful at describing the behavior of matter at the atomic level. This success forces one to accept that certain aspects of physical reality go far beyond our intuition. Among these, none ...
