Summary
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 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.

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.
The iceberg's survival after colliding with an island means it remains a large, mobile hazard

Summary
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.
Radio galaxies may become observationally invisible far sooner after their jets shut down than existing

Faster fading means current surveys may miss a large share of black hole activity after jets switch off.
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.
Summary
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.

Summary
A nine-year study of morning glories found that their rate of adaptation fell by 96% as climate pressures and pollinator scarcity pulled evolution in competing directions. The plants retained substantial genetic diversity, so the slowdown was not caused by a lack of variation.

Seismic data indicate that Mars once contained enormous magmatic systems in which molten rock repeatedly evolved and recycled through the crust across hundreds or thousands of kilometers. The evidence suggests complex crust formation without the Earth-like plate tectonics previously thought necessary.
