UCLA researchers found that radial glia, the stem cells that produce much of the cerebral cortex, respond to both glucose processing and physical signals from the thalamus. These influences can change which neurons the developing brain produces, including upper-layer neurons that are especially prominent in humans.

A severe drought has expanded across Puerto Rico during what is normally the rainy season, with 44 percent of the territory in extreme drought by August 25 and some areas receiving less than one-fifth of normal rainfall. Water rationing, crop losses, and feed shortages have prompted local and federal disaster declarations.

The LUX-ZEPLIN experiment recorded a rare particle interaction that is difficult to explain as ordinary background noise and appeared in a region where dark matter might be expected. Researchers are not calling it a discovery because the result rests on a single event and requires more data.

Brain formation depends on local cell metabolism and incoming signals, not just an inherited cellular blueprint.

A severe drought has expanded across Puerto Rico during what is normally the rainy season, with 44 percent of the territory in extreme drought by August 25 and some areas receiving less than one-fifth of normal rainfall. Water rationing, crop losses, and feed shortages have prompted local and federal disaster declarations.
The immediate shift is from a seasonal dry spell to a territory-wide water and agricultural

A drought during the wet season is exhausting water and food buffers before Puerto Rico can replenish them.
Summary
The LUX-ZEPLIN experiment recorded a rare particle interaction that is difficult to explain as ordinary background noise and appeared in a region where dark matter might be expected. Researchers are not calling it a discovery because the result rests on a single event and requires more data.
The decisive fact is not evidence of dark matter, but an unexplained event that survived

One anomalous event could guide a major search, but it currently falls far short of establishing new physics.
A curated list of other prominent stories from this day.
Researchers found that bonnethead sharks of both sexes start life with relatively pointed heads that become rounder as they age, with the shift strongest in females. This overturns the idea that only mature males develop a pointed snout.

Harvard researchers used elastic yarns and industrial knitting methods to make thick fabrics that snap between multiple stable shapes. Conductive yarns turned the textiles into soft switches that can control lights, count steps, and respond to movement.

The Ig Nobel prizes honored research on cockroach milk, the evolutionary history of kissing, buried underwear and the science of blowing one’s nose. The ceremony was held outside the United States for the first time.

A compound called plasmalogen, found in edible sea squirts, improved memory, learning, brain-cell connections, inflammation, and hair growth in older mice. Researchers say it may support brain regeneration and protect aging synapses.

MIT researchers engineered bacteria that function as transistors and can be linked into living circuits to perform calculations and control chemical signals. The eventual goal is to deploy them on plant roots or leaves to detect threats and activate defenses.

Slow breathing with a prolonged exhale changed heart activity and increased the brain's sensitivity to rewards, making participants more willing to take risks. The findings suggest that breathing patterns can influence how people evaluate uncertain choices.

An iceberg larger than 76 square kilometers broke from Greenland's Petermann Glacier in August 2026, the Arctic's largest such calving event since 2020. It later struck Joe Island without breaking apart and is now being tracked as it moves through Nares Strait.

Astronomers identified a young group of fading radio galaxies whose supermassive black holes have already stopped producing powerful jets. The confirmed remnants are roughly 8 to 42 million years old, and distant examples appear to fade especially quickly.

Researchers found that bonnethead sharks of both sexes start life with relatively pointed heads that become rounder as they age, with the shift strongest in females. This overturns the idea that only mature males develop a pointed snout.
The decisive change is a reversal of the shark’s presumed development: the pointed head is

Correcting the growth pattern prevents scientists from mistaking age-related variation for a sex-specific adaptation.

Harvard researchers used elastic yarns and industrial knitting methods to make thick fabrics that snap between multiple stable shapes. Conductive yarns turned the textiles into soft switches that can control lights, count steps, and respond to movement.

A compound called plasmalogen, found in edible sea squirts, improved memory, learning, brain-cell connections, inflammation, and hair growth in older mice. Researchers say it may support brain regeneration and protect aging synapses.
The finding extends plasmalogen research from cellular protection toward a broader anti-aging effect, but the

A huge intact iceberg is now moving through a constrained Arctic route, creating a live hazard and a marker of glacier change.

Astronomers identified a young group of fading radio galaxies whose supermassive black holes have already stopped producing powerful jets. The confirmed remnants are roughly 8 to 42 million years old, and distant examples appear to fade especially quickly.
