Phys.org / Most sensitive radio observations to date find no evidence of technosignature from 3I/ATLAS
Since the interstellar object (ISO) 3I/ATLAS was first discovered on July 1, 2025, it has garnered much attention, including speculation, hopes and fears that it may somehow contain evidence of technologically advanced civilizations ...
Phys.org / Hunting for dark matter axions with a quantum-powered haloscope
Axions are hypothetical light particles that could solve two different physics problems, as they could explain why some nuclear interactions don't violate time symmetry and are also promising dark matter candidates. Dark ...
Phys.org / 2025 was one of three hottest years on record, scientists say
Climate change worsened by human behavior made 2025 one of the three hottest years on record, scientists said.
Phys.org / Scientists have uncovered evidence of Ireland's largest prehistoric hillfort settlement
In a recent study published in Antiquity, Dr. Dirk Brandherm and his colleagues identified more than 600 suspected house platforms in the Brusselstown Ring hillfort, making it the largest nucleated settlement ever discovered ...
Phys.org / ASKAP discovers a spectacular outflow in a nearby galaxy
Using the Australian Square Kilometer Array Pathfinder (ASKAP), an international team of astronomers has discovered a spectacular bipolar outflow from the disk of a nearby galaxy known as ESO 130-G012. The finding was reported ...
Phys.org / Mathematicians crack cellular noise puzzle, paving path for better cancer treatment
Why does cancer sometimes recur even after successful treatment, or why do some bacteria survive despite the use of powerful antibiotics? One of the key culprits identified is "biological noise"—random fluctuations occurring ...
Phys.org / NASA's Chandra rings in the new year with the Champagne Cluster
Celebrate the New Year with the "Champagne Cluster," a galaxy cluster seen in this new image from NASA's Chandra X-ray Observatory and optical telescopes.
Phys.org / AI model uses social media posts to predict unemployment rates ahead of official data
Social media posts about unemployment can predict official jobless claims up to two weeks before government data is released, according to a study. Unemployment can be tough, and people often post about it online.
Phys.org / Encoding adaptive intelligence in molecular matter by design
For more than 50 years, scientists have sought alternatives to silicon for building molecular electronics. The vision was elegant; the reality proved far more complex. Within a device, molecules behave not as orderly textbook ...
Phys.org / Simple wipe test reveals hidden PFAS contamination on firefighter protective gear
The flames die down. The sirens fade. Firefighters peel off their gear, thinking the danger has passed. But in the quiet aftermath, another enemy lingers, an invisible film of "forever chemicals" clinging to jackets, pants ...
Phys.org / New dataset maps global city boundaries in high resolution from 2000 to 2022
A research team led by Prof. Liu Liangyun from the Aerospace Information Research Institute of the Chinese Academy of Sciences (AIRCAS) has produced the first comprehensive, high-resolution map of global city and town boundaries, ...
Phys.org / Ethylene and oxygen found to drive periderm regeneration after plant injury
Plants have an extraordinary ability to sense tissue damage and quickly rebuild their protective outer layers, a process vital for survival amid environmental stresses. The periderm—a specialized protective tissue found ...
