Phys.org / Chemists pioneer light-driven macrolactone synthesis for fast route to complex natural compound
Macrolactones—large ring lactones—are core components of many natural products and pharmaceutical agents. Traditional synthetic routes rely on seco acids activated with condensing reagents, often requiring harsh conditions ...
Phys.org / Rich cities, broke neighbors: Study exposes metro-level wealth divide
Local governments in the United States are responsible for many of the services people rely on daily—schools, parks, public safety, and more. But the resources available to fund these services depend heavily on the amount ...
Phys.org / Fish freshness easily monitored with a new sensor
To see if a fish is fresh, people recommend looking at its eyes and gills or giving it a sniff. But a more accurate check for food quality and safety is to look for compounds that form when decomposition starts.
Tech Xplore / Yes, the government can track your location, but usually not by spying on you directly
If you use a mobile phone with location services turned on, it is likely that data about where you live and work, where you shop for groceries, where you go to church and see your doctor, and where you traveled to over the ...
Tech Xplore / OpenAI awards $40.5M to a wide range of nonprofits under new foundation structure
OpenAI will award $40.5 million to more than 200 nonprofits before the end of the year, following an open call for applications in September.
Tech Xplore / What are small modular reactors, a new type of nuclear power plant sought to feed AI's energy demand?
As U.S. electricity demand rises and technology companies seek to build more and larger data centers to drive artificial intelligence systems, the main question arising is how to generate all that power.
Phys.org / Coastal regions and climate change: How better risk assessment can help protect infrastructure and livelihoods
Coastal regions, where dense clusters of critical infrastructure are found, are facing the sharpest edge of climate change. The threats include paralyzed transport networks and disrupted supply chains. To stay ahead, we need ...
Phys.org / Visual thinking: The strategy that could help you spot misinformation and manipulated images
A fake photo of an explosion near the Pentagon once rattled the stock market. A tearful video of a frightened young "Ukrainian conscript" went viral: until exposed as staged. We may be approaching a "synthetic media tipping ...
Phys.org / Federal funding cuts are only one problem facing America's colleges and universities
Higher education is under stress. The highest-profile threat has been the Trump administration's efforts to cut funding to several universities, including Harvard, Columbia and Northwestern.
Medical Xpress / Diabetes drugs may help older adults slow frailty
A new study shows that older adults with type 2 diabetes who start treatment with sodium–glucose cotransporter-2 (SGLT-2) inhibitors—such as empagliflozin (Jardiance) and dapagliflozin (Farxiga)—or glucagon-like peptide-1 ...
Medical Xpress / Sneaky senescent cells that resist cancer treatment can provide druggable lung cancer target
Senescent fibroblasts are aging cells that no longer divide and protect against tumor development. Yet two decades have gone by since cell biologist Judith Campisi, Ph.D., paradoxically demonstrated that these same cells ...
Phys.org / Lemon shark caught preying on invasive freshwater fish in Fernando de Noronha, Brazil
Researchers recorded lemon sharks (Negaprion brevirostris) preying on an invasive species, the jaguar cichlid (Parachromis managuensis), for the first time. This observation was made in Sueste Bay in March 2024. Sueste Bay ...
