Phys.org / Chemists overturn 40-year assumption about a key class of superconductors
Scientists at Warwick have shown that a material treated for 40 years as a uniform, textbook superconductor is in fact a patchwork of different crystal structures throughout its bulk, using an advanced 3D imaging technique ...
Phys.org / New krypton-88 data narrow a key gap in stellar strontium models
An international research team has reported the first experimental investigation of a nuclear physics reaction essential for understanding how the element strontium is produced in stars—specifically in stellar environments ...
Phys.org / Half-billion-year-old fossils rewrite the origin story of starfish
Scientists have discovered several 518-million-year-old fossils that reshape understanding of the origins of the animal group containing starfish. The fossils show that these animals ate using tentacles rather than passively ...
Phys.org / SpaceX prepares for first orbital flight of Starship rocket
SpaceX announced Tuesday that it was planning to send its flagship rocket, Starship, into orbit, a key step in its project to one day reach the moon or Mars.
Medical Xpress / REM and deep sleep, not just total sleep time, associated with disease risk
Greater amounts of REM and deep sleep were associated with lower risks of dozens of diseases, and less than 5 hours of total sleep was associated with high disease risks, according to a new study published Sept. 17 in the ...
Medical Xpress / From 7,000 drugs to one active against resistant strains: AI advances pneumonia drug repurposing
Streptococcus pneumoniae is a bacterial pathogen that causes life-threatening infections, including pneumonia and meningitis. These infections are commonly treated with antibiotics, but antibiotics are becoming less effective ...
Phys.org / AI updates can sometimes feel like breakups or losses, study finds
Artificial intelligence systems, particularly those powered by large language models and designed to communicate with users on a one-to-one basis, are increasingly used worldwide. Some of these systems, such as Replika, are ...
Phys.org / A new bridge for quantum networks: Physicists convert microwaves to light using 2D magnets
Physicists at The City College of New York have demonstrated a new way to transfer microwave signals onto light using magnetic waves inside a layered semiconductor. The work establishes a materials platform for building interfaces ...
Medical Xpress / Ebola vaccine being tested in DR Congo outbreak zone
Health workers in parts of the Democratic Republic of Congo badly hit by a deadly Ebola outbreak launched a test vaccination program Saturday to see whether vaccines designed for a different strain of the virus could prove ...
Phys.org / Black holes from stellar to supermassive size may follow one jet-launching rule
An early-career Western Australian astrophysicist has helped uncover a universal rule behind one of the most powerful behaviors in the universe: when black holes launch jets. The discovery, published in the journal Nature ...
Phys.org / Tiny atomic tweak makes plastic-eating enzymes more powerful
A new approach that changes just one atom in plastic-degrading enzymes could help make them more efficient while maintaining their stability, according to new research from The Australian National University published in ...
Medical Xpress / Teaching the immune system to control HIV
There is no cure for HIV. While scientists have made considerable progress in controlling the infection, patients still must take daily antiretroviral medication for the rest of their lives. Results from a clinical trial ...
