Phys.org / Evidence of cosmic-ray acceleration from a nearby supernova remnant

Cosmic rays seen at Earth show a wide range of particle energies, from 107 electron-volts (eV) to more than 1020 eV, the latter being about the same as the kinetic energy of a 450 gram football (soccer ball) being kicked ...

Phys.org / Rainfall near 700 mm marks turning point in ecosystem nitrogen retention

In a study published in Nature Geoscience, a research team led by Prof. Liu Lingli from the Institute of Botany of the Chinese Academy of Sciences (IBCAS) has identified a mean annual precipitation (MAP) threshold of approximately ...

Phys.org / Saturday Citations: Failure to launch; cellular mortality; heavy weather

Highlights from the last week of May, 2026: A key climate tipping point is disrupting the Arctic Ocean food chain (more of a lowlight, I guess). Scuba-diving tourism may not be the benefit to coral reef systems that we once ...

Phys.org / Ohio wall lizards overcame genetic bottleneck through rapid population boom, genomes reveal

Non-native wall lizards living in Cincinnati, Ohio, have thrived against the odds thanks to an ability to expand their population more quickly than any inbreeding-amplified harmful genes could weaken their chances for survival, ...

Phys.org / Webb reveals black hole that formed before its galaxy

Which comes first, the galaxy or the black hole? We don't know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can ...

Phys.org / Mars's manganese 'bathtub ring' reveals ancient ocean timeline and its potential for life

Past research has indicated Mars's largest northern basin, Utopia Planitia, was once the location of a large body of water, but details surrounding when this body of water may have existed have not been resolved. Researchers ...

Phys.org / Tardigrades reveal extreme heat-blocking survival trick while in tun state

Tardigrades, also known as water bears or moss piglets, are tiny eight-legged animals that can survive in extreme environments, where humans and most other animals would die. This resistance to extreme conditions, including ...

Phys.org / 'Shoot for the moon?' Aim a bit lower, researchers say

How ambitious should you be? Folk wisdom offers conflicting advice: "Shoot for the moon," but also, "Don't let the perfect be the enemy of the good." A new study by researchers at the University of Wyoming, Stanford University ...

Phys.org / A hidden supermassive black hole may be lurking inside the Antennae galaxies

Astronomers may have uncovered a hidden supermassive black hole inside the famous Antennae galaxies NGC 4038/4039, a pair of colliding galaxies best known for their spectacular bursts of star formation. The paper outlining ...

Phys.org / Topological states emerge in quantum Hall-superconductor devices with multiple channels

Topological phases are unusual states of matter that give rise to properties protected by a material's overall structure (i.e., "topology"), as opposed to microscopic details. These phases are of great interest for the development ...
