Mon, 20 Jul 2026 23:51:43 EDT https://www.sciencedaily.com/releases/2026/07/260719035951.htm https://www.sciencedaily.com/releases/2026/07/260719035947.htm A new theoretical study offers a possible explanation for how the Universe can grow more complex without violating the second law of thermodynamics. Using a quantum gravity framework called Gravity from Entropy, mathematician Ginestra Bianconi found that the Universe’s total entropy may rise as space expands, even while entropy within each unit of volume falls. That decline could leave room for galaxies, stars, planets, and life to form locally amid an overall increase in cosmic entropy. Mon, 20 Jul 2026 22:40:55 EDT https://www.sciencedaily.com/releases/2026/07/260719035947.htm https://www.sciencedaily.com/releases/2026/07/260719035942.htm Dying Sun-like stars may not fade away quietly. As blobs of gas erupt unevenly from their swollen surfaces, each burst gives the star a tiny push in the opposite direction. Thousands of these random kicks could eventually break apart distant stellar pairs or, in rare cases, drive two stars into a violent collision. Mon, 20 Jul 2026 23:36:16 EDT https://www.sciencedaily.com/releases/2026/07/260719035942.htm https://www.sciencedaily.com/releases/2026/07/260719035931.htm Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells. In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, restorative sleep. Temporarily removing most of these cells restored more than two hours of sleep per day, even though the plaques remained unchanged. Mon, 20 Jul 2026 06:05:34 EDT https://www.sciencedaily.com/releases/2026/07/260719035931.htm https://www.sciencedaily.com/releases/2026/07/260718010200.htm Scientists have redesigned zinc oxide particles to create a mineral sunscreen that protects against ultraviolet radiation without leaving such a noticeable white cast.

In the scientific journal Physical Review Letters, they show that this theory does not necessarily need to be formulated with imaginary numbers – real numbers can in fact also be used. The American Physical Society has also dedicated a “Highlight” to these findings in its Physics Magazine.

A newly identified "commander" cell appears to coordinate this system, helping the eye detect faint details that might otherwise be missed.

The advance may improve our understanding of black hole mergers, evaporation, and the powerful gravitational wave events detected by observatories like LIGO.

Instead of relying on expensive, highly engineered materials, they simply shine a laser at a tiny circular disc, producing stable swirling patterns in light that researchers believe could one day help power advanced data storage, communications, and computing technologies.

Researchers found that extensive training physically reorganizes the brain, allowing learned tasks to bypass the prefrontal cortex and run through specialized circuits instead. By freeing the brain's "thinking" center, people became better at performing another task at the same time, challenging the long-held idea that humans only switch rapidly between tasks rather than truly multitask.

Researchers found that even primary sensory regions are influenced by higher brain areas through rapid feedback loops, rather than simply passing information forward. This more dynamic view of brain function could help engineers design future AI systems that think more like biological brains while using far less power.

In a small clinical trial, people with a history of depression who took the medication prucalopride for about a week performed better on tests of memory, attention, and thinking speed than those who received a placebo. The drug targets a serotonin receptor found in both the gut and the brain, and researchers saw no significant side effects.

Advanced software analyzed millions of signals, filtering out Earth-based interference and other false positives. No convincing artificial radio transmissions were found, but the project demonstrated a powerful new approach that will make future SETI searches faster and far more effective.

The data indicate the planet likely has a hydrogen-rich atmosphere shaped by gases escaping from its molten interior, with signs that volcanic outgassing may even create temporary clouds.
