Phys.org / What if dark matter came in two states?
The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark matter, showing that it ...
Phys.org / The lengths male octopuses go to protect the arm they need to mate
For mating male octopuses, one limb is more important than all others. That is the third right arm or hectocotylus, which is used to transfer sperm to the female because the penis cannot do it directly. Losing the limb can ...
Phys.org / Ecuador study finds tropical rainforest biodiversity rebounds over 90% in 30 years
Tropical rainforests are home to almost two-thirds of all vertebrate species and three-quarters of all tree species: they are the most species-rich terrestrial ecosystem on Earth. However, over half of these diverse rainforests ...
Phys.org / A 'stemness checkpoint' helps control stem cell identity
A study published in Cell Research advances a central idea in stem cell biology by identifying a checkpoint that controls the identity of many different types of stem cells across developmental stages. For nearly two decades, ...
Phys.org / Physicists zero in on the mass of the fundamental W boson particle
When fundamental particles are heavier or lighter than expected, physicists' understanding of the universe can tip into the unknown. A particle that is just beyond its predicted mass can unravel scientists' assumptions about ...
Phys.org / AMOC collapse could turn Southern Ocean into carbon source, adding 0.2°C to global warming
A shutdown of the Atlantic Meridional Overturning Circulation (AMOC) could trigger a substantial release of stored ocean carbon into the atmosphere over hundreds of years, according to a new study that simulated such a collapse ...
Phys.org / Unique double baptistery and mysterious marble block uncovered at Byzantine cathedral in Israel
In a new article published in the Palestine Exploration Quarterly, researchers Dr. Michael Eisenberg and Dr. Arleta Kowalewska describe a recently excavated Byzantine-period cathedral at Hippos. Archaeologists revealed a ...
Phys.org / Satellites capture the volatile human–luminescence relationship
From space, Earth's populated areas glow on the otherwise "black marble" of the planet at night. For decades, scientists assumed this glow was steadily increasing as the world developed. However, a new study published in ...
Phys.org / AI uncovers hidden immune defenses inside bacteria
Researchers at the Massachusetts Institute of Technology (MIT) have discovered thousands of new proteins that protect bacteria from virus attacks using an AI system called DefensePredictor. What would usually take months ...
Medical Xpress / AAD: Subcutaneous amlitelimab aids atopic dermatitis outcomes through week 24
Amlitelimab, a fully human non-T cell depleting monoclonal antibody that selectively targets OX40-ligand (OX40L), is safe and effective, with potentially progressive efficacy over time, for patients with moderate-to-severe ...
Phys.org / Ancient architecture shows public opinion influenced Maya divine kings
Excavation of a council house at the major Lowland Maya center of Ucanal, Guatemala, reveals how the public gained some influence over Maya politics more than 1,000 years ago. These colonnaded, open halls were likely council ...
Phys.org / Mathematical model predicts fish freshness in real time
Every day, fish caught in oceans and seas around the world pass through a long journey before reaching supermarkets, restaurants, and home kitchens. Along the way, their freshness steadily declines, often in ways that are ...
