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 / 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 ...
Phys.org / The Star of Bethlehem might have actually been a comet described in an ancient Chinese text
Many researchers have spent decades attempting to decode biblical descriptions and link them to verifiable historical events. One such description is that of the Star of Bethlehem—a bright astronomical body that was said ...
Phys.org / Biology-inspired brain model matches animal learning and reveals overlooked neuron activity
A new computational model of the brain based closely on its biology and physiology has not only learned a simple visual category learning task exactly as well as lab animals, but even enabled the discovery of counterintuitive ...
Phys.org / Ancient Puebloans kept macaws and parrots in great houses for ceremonial use
In a recent study, Dr. Katelyn Bishop conducted a zooarchaeological and archival data reanalysis of macaws and parrots recovered from Chaco Canyon to better understand their depositional contexts, material associations, and ...
Phys.org / Twisted light-matter systems unlock unusual topological phenomena
Properties that remain unchanged when materials are stretched or bent, which are broadly referred to as topological properties, can contribute to the emergence of unusual physical effects in specific systems.
Phys.org / Sugar-derived crystals show stiffness approaching that of aluminum
Mucic acid crystals grown from a water-based solution achieved a record-breaking stiffness for an organic crystal.
Phys.org / Using microwave pulses to plug leaks in quantum computers makes them more reliable
Scientists have developed a new approach to correcting common quantum computing errors, which could pave the way for more reliable systems.
Phys.org / Aluminum cans are a viable alternative to bottles for red muscadine wine, new study finds
One of the main reasons wine traditionally comes in bottles is to protect its quality. Glass is nonreactive, and the cork or screw cap provides an airtight seal that prevents oxygen from spoiling the liquid. In recent years, ...
Phys.org / Veritas explores the nature of a mysterious gamma-ray emitter
Astronomers have employed the Very Energetic Radiation Imaging Telescope Array System (VERITAS) to observe a mysterious gamma-ray emitting source designated HESS J1857+026. Results of the observational campaign, published ...
Phys.org / Men embodying women in VR report strong emotional reactions to verbal harassment
Unfortunately, many women and girls know all too well what it means to be victims of verbal harassment. They are familiar with its emotional and psychological impact. What about men? What would they feel if they were in the ...
