Phys.org / Insects in the tropics are already near their heat limits. Climate change could push many beyond survival
Insects make up to 90% of all animal species on the planet, and most of them can be found in the tropics, the regions around the equator. Yet we still know surprisingly little about how these species will cope with rising ...
Medical Xpress / Truth, or misinformation? A statistician explains the challenge of assessing evidence
When United States Health Secretary Robert F. Kennedy Jr. unveiled new dietary guidelines earlier this year to "Make America Healthy Again," they received a mixed response.
Medical Xpress / 'My head feels clearer': How citizen science can improve people's health
The two of us can often be found in a patch of scrubby bushland, phone in hand, slowly scanning for plants. Or crouched behind a tree trunk with binoculars, pausing mid-breath to find the source of a bird call. It often feels ...
Phys.org / The secrets of black holes and the Higgs mass could be hidden in a 7-dimensional geometry
One of the greatest mysteries of modern physics, the "black hole information paradox," might have finally found an elegant solution, and the answer could also reveal the origins of the mass of fundamental particles.
Phys.org / Image: NISAR views Mount St. Helens
This image captured by U.S.-Indian Earth satellite NISAR on Nov. 10, 2025, shows Washington's Mount St. Helens. The image is cropped from a much larger swath spanning the Pacific Northwest on a cloudy day; NISAR's L-band ...
Phys.org / The most pristine star yet found in the known universe
An unusual team of astronomers used Sloan Digital Sky Survey-V (SDSS-V) data and observations on the Magellan telescopes at Carnegie Science's Las Campanas Observatory in Chile to discover the most pristine star in the known ...
Phys.org / Unexplained sky flashes from the 1950s: Independent analysis supports their existence
Historical observations from an observatory in Germany have now independently verified evidence for brief, mysterious flashes of light in the night sky, first picked up by an American astronomical survey in the 1950s. Through ...
Phys.org / Terraforming Mars: Modeling engineered aerosols to warm the planet
Whenever humans arrive on Mars, they're going to find it a difficult place to exist. Mars is cold, with an average surface temperature of -55°C; temperatures can plunge to -125°C with dust storms lasting months; its atmosphere ...
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 / Tiny African fish caught climbing to the top of a 50-foot waterfall
For over half a century, people in Central Africa have told tales of the fish seen climbing waterfalls, but these claims have never been officially confirmed. Now, these fish have finally been caught on camera, studied more ...
Phys.org / Astronomers find a third galaxy missing its dark matter, validating a violent cosmic collision theory
Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense gravitational pull, the rotational spins of galaxies would force them to simply fly apart. But now, ...
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 ...
