Phys.org / Bilayer antiferromagnet reveals photocurrent that flips with magnetic state
In recent years, atomically thin materials—crystals only a few atoms thick—have attracted growing attention because they can exhibit physical properties that do not appear in conventional bulk materials. Among them, atomically ...
Phys.org / Copper-based sensor explains key defense signaling in stressed plants
Researchers at the Institute of Transformative Bio-Molecules (WPI-ITbM), Nagoya University, together with collaborators from RIKEN Center for Sustainable Resource Science (RIKEN CSRS) and The University of Osaka, have uncovered ...
Phys.org / People overestimate how confident AI systems are in their responses, experiments reveal
Artificial intelligence (AI) systems, particularly conversational agents such as ChatGPT or Gemini, are now used daily by a growing number of people worldwide. While many users trust the answers of AI agents to their queries, ...
Phys.org / eROSITA discovers a 'changing-look' Seyfert galaxy
Astronomers have tracked a dramatic "changing-look" active galactic nucleus (AGN) whose central supermassive black hole appeared to switch off and then rapidly reignite. The galaxy, HE 1237−2252, dimmed in X-rays by a factor ...
Phys.org / Neutrino flavor flips could be key to triggering supernovae
Despite being so elusive, neutrinos are produced in abundance in some of the most violent events in the universe. One of their strangest properties is that they can spontaneously switch between three types, or "flavors": ...
Phys.org / Roadmap charts three paths to room-temperature quantum materials for cooler computing
Imagine a laptop that never gets hot, a phone that holds its charge for days, or a computer memory chip designed to permanently retain data, even when the power goes out. This is the possibility sitting inside a remarkable ...
Phys.org / Surrounded by stardust: Antarctic ice cores confirm Earth is accumulating iron-60 from local interstellar cloud
Our solar system is currently passing through the Local Interstellar Cloud, a region of highly diluted gas and dust between the stars. On its path, Earth continuously accumulates iron-60, a rare radioactive isotope of iron ...
Phys.org / When politics enter the picture, credentials take a back seat
Most Americans know what a real expert's credentials look like: relevant degree, years of experience, and respect from peers. The problem, according to a study recently published in Scientific Reports, is that none of it ...
Phys.org / Hidden cell networks emerge in 3D as new nanoscopy tracks living bridges
A new nanoscopy technique developed at The Australian National University (ANU) has uncovered hidden networks used for communication between cells, opening new ways to understand human diseases. Described in an article published ...
Phys.org / First outbursting hot subdwarf binary discovered
An international team of astronomers has utilized the Zwicky Transient Facility (ZTF) and the Transiting Exoplanet Survey Satellite (TESS) to investigate a binary system designated ZTF J0007+4804. As a result, they have found ...
Phys.org / Why some water fleas suddenly grow helmets: Key receptors reveal how predator warnings trigger defense
Daphnia, commonly known as water fleas, are tiny crustaceans that live in freshwater ponds and lakes. When they sense predators in their surroundings, these small organisms can swiftly move away or adapt their body shape, ...
Phys.org / Medieval teeth open a new perspective on leprosy care and toxic medicine
A recent study published in the Journal of Archaeological Science, led by Dr. Elena Fiorin and her colleagues investigated the potential use of mercury-based treatments for leprosy during the late medieval period. Typically, ...
