Physicists create a bizarre new quantum state called a fractional fermi sea

Summary

Physicists have created a highly excited but orderly state of ultracold atoms known as a fractional Fermi sea. Its unusual organization does not fit familiar quantum descriptions and may involve previously unobserved quasiparticles dubbed potential "super-Fermions."

The discovery expands the catalog of possible quantum matter beyond systems governed by conventional Fermi

Scientists who discovered a third form of magnetism win major physics prize

Summary

Researchers whose work identified altermagnetism have received a major physics prize. The magnetic order differs from conventional ferromagnetism and antiferromagnetism, creating a new framework for understanding magnetic materials.

Altermagnetism turns a theoretical distinction into a potential materials platform for electronics and quantum devices.

Two monster black holes could collide in just 100 years

Summary

Astronomers found evidence that the galaxy Mrk 501 contains two supermassive black holes orbiting each other, including a previously unseen particle jet linked to the second object. The pair may complete an orbit every 121 days and could merge within roughly a century, depending on their masses.

The possible second black hole changes Mrk 501 from a jet-producing galaxy into a rare

Magic mushroom ingredient takes the fight out of aggressive fish

Summary

Low doses of psilocybin reduced aggressive attacks in mangrove rivulus fish without disrupting their ordinary social behavior. The result suggests the compound may dampen escalation specifically rather than broadly suppressing activity.

The key shift is behavioral selectivity: psilocybin appeared to reduce aggression while preserving normal interaction.

Why it matters

The study could help separate treatments that reduce harmful aggression from those that blunt behavior more generally.

Scientists discover a surprising twist in Japan's 7,300-year-old volcanic apocalypse

Summary

New research shows that a massive volcanic eruption in Japan 7,300 years ago did not produce a uniform demographic collapse. Some communities declined or vanished, while others grew as survivors migrated, adapted, and rebuilt in less affected areas.

The evidence shifts the story from simple disaster to uneven regional disruption. Population resilience depended
