AI for homework—parents more willing to pay subscriptions for their children as peer pressure rises‎

Many parents have mixed feelings about the unrestricted use of artificial intelligence (AI) for schoolwork. They are concerned about the potential impact on their child's ability to learn but also don't want them to be left behind if other young people are using AI.

Bacterial enzyme switch could weaken antibiotic defenses in MRSA and other pathogens‎

If you ask Vijay Parashar, associate professor of medical and molecular sciences (MMSC) at the University of Delaware College of Health Sciences, human bodies are bags of bacteria. "It sounds gross, but not all bacteria are bad; most of them are good. The trouble starts when the bad bacteria learn how to outsmart antibiotics."

An elegant modification doubles the range of low-noise 'white lasers' in a single fiber‎

Supercontinuum light sources—often called "white lasers" because they emit a broad, continuous rainbow of colors—are essential tools for everything from advanced medical imaging to environmental gas detection. However, researchers have historically faced a frustrating trade-off: A broad spectrum comes at the expense of high fluctuations, which has effectively limited their use.

Q&A: Mushroom behind 'tiny people' hallucinations identified‎

People in communities thousands of miles apart have described the same strange experience after eating a mysterious mushroom: vivid visions of tiny humans moving through and interacting with the physical world around them. Known as Lilliputian hallucinations—a reference to the 6-inch-tall inhabitants of "Gulliver's Travels"—the phenomenon has long been thought to stem from cultural influences rather than biology.

Charting the galaxy: Milky Way Mapper survey releases latest all-sky spectra‎

The Sloan Digital Sky Survey V (SDSS-V) has announced its 20th public data release (DR20), delivering a dramatic expansion of the Milky Way Mapper (MWM) scientific survey—the most detailed spectroscopic map yet assembled of stars in and around our home galaxy.

One ant can trigger colony-wide activity bursts, mathematical model suggests‎

Scientists have long known that ant colonies sometimes seem to move as one. A nest that appears quiet can suddenly erupt into activity, with workers throughout the colony springing into motion almost simultaneously before settling back into stillness.

Decoding the North American bison's genome to better inform conservation efforts‎

A new study by ancient DNA researchers at the University of California, Santa Cruz, used paleogenomics to create a genetic roadmap to help guide the restoration of another iconic species once on the brink of extinction: the North American bison.
