Phys.org / Ancient genome duplications laid the foundations of complex brains, research suggests
New findings, published in Nature, help answer the riddle of how vertebrates evolved the diverse array of brain cells that distinguishes them from other animals. It appears that a dramatic expansion of the genetic toolkit ...
Phys.org / How bacteria use acetyl coenzyme as a building block in the formation of cells
Researchers at the University of Greifswald have discovered a new mechanism by which bacteria such as Bacillus subtilis can regulate the production of the central metabolic molecule acetyl coenzyme A (Acetyl-CoA). Acetyl-CoA, ...
Tech Xplore / Rising from the ashes, a hidden supply of critical elements emerges
Anuja Tripathi grew up in Kanpur, India, where coal fly ash from a nearby power plant coated rooftops, windowsills and laundry hung outside to dry.
Medical Xpress / Prenatal health and early diet may shape fatty liver risk, study suggests
The accumulation of excess fat in the liver is not solely a consequence of the combined effects of hereditary and adult lifestyle-related factors. A new study by researchers at Tampere University and the University of Eastern ...
Tech Xplore / Anthropic says it has taken its latest AI models offline to comply with new export controls
AI giant Anthropic said Friday it has taken its latest artificial intelligence models, known as Fable 5 and Mythos 5, offline to comply with a directive from the Trump administration to prevent their use by foreign nationals.
Phys.org / Why this $10 spectrometer chip could bring real-time chemical sensing to wearables
Researchers from the University of Cambridge and GlitterinTech, a startup founded by the same research group, have unveiled a fundamentally new type of optical spectrometer that delivers laboratory-grade precision in a device ...
Phys.org / Meet REMORA: The autonomous space fleet built to tag and track asteroids
To truly understand what an asteroid is made of, we need to send a probe to it. Remote sensing from ground-based telescopes, or even orbiting observatories, can only do so much. A new white paper submitted to the U.K. Space ...
Phys.org / Water molecule unlocks faster interfacial polymerization by lowering energy barrier
Researchers at The Hong Kong University of Science and Technology (HKUST) have achieved two major breakthroughs in interfacial polymerization, a key technique for preparing advanced functional materials. By integrating quantum ...
Phys.org / Cells have a secret power line: How the nucleus gets its own private energy supply from mitochondria
For decades, biologists assumed a cell's energy simply diffused to wherever it was needed. It turns out the most important destination of all has a private delivery line.
Tech Xplore / Self-regenerating catalyst overcomes key durability challenge in hydrogen energy
Imagine a catalyst that can heal itself after being damaged. A POSTECH-led research team has developed an electrocatalyst that regenerates its own metallic surface after oxidation, much like how a wound heals naturally. This ...
Medical Xpress / GLP-1s tied to elevated risk of fainting, dizziness
Northwestern Medicine scientists have identified a safety concern associated with GLP-1 drugs. Using health record data, the research team tracked more than 42,000 adults already taking at least two types of blood pressure ...
Phys.org / Ocean glow meets 3D printing with living gels that sense mechanical force
The integration of biological organisms into synthetic structures offers a radical new pathway for developing intelligent, self-powered materials. Researchers have pioneered an innovative approach to biomanufacturing by using ...
