Missing mass of the Milky Way may be hiding in interstellar comet swarms

The discovery of comet 3I/ATLAS has fuelled a striking hypothesis: part of our galaxy's unaccounted mass could be locked away in billions of wandering comets.

  • Comet 3I/ATLAS inspired a new hypothesis about the Milky Way's undetected mass.
  • Swarms of billions of interstellar comets could store large amounts of uncharted baryonic matter.
  • Data from 3I/ATLAS enable the first concrete estimates of the wandering comet population.

Laughter shapes children's brains more than previously thought

An early childhood expert at Middlesex University argues that laughter plays an active role in the neurological development of young children.

  • Laughter activates key neural circuits during a child's earliest years.
  • Humour-filled interactions strengthen attachment and stimulate learning.
  • Specialists recommend deliberately including play in daily routines.

Scientists pinpoint a tiny brain circuit that drives anxiety — and can reverse it

Researchers identified a small, precise neural circuit that triggers anxiety and social withdrawal, and showed that rebalancing it can switch those symptoms off.

  • A precise brain circuit was directly linked to triggering anxiety and social isolation.
  • Restoring balance in the circuit reversed symptoms in the experimental models studied.
  • The discovery offers a specific neurological target for future anti-anxiety therapies.

Deep earthquakes found where they should not exist, under Utah

Scientists have identified a hidden class of deep-focus earthquakes beneath Utah, overturning decades-old assumptions about where seismic activity can occur.

  • Deep-focus earthquakes detected beneath Utah, where standard theory ruled them out.
  • The find contradicts seismological models established over several decades.
  • Research raises new questions about the internal dynamics of the Earth.

A rare meteorite hints at a vanished fifth rocky planet

The early Solar System may have harboured more rocky planets than today's four. An unusual meteorite offers new clues about a long-lost world.

  • A meteorite with no chemical match in the modern Solar System has puzzled researchers.
  • The data suggest an additional rocky planet once existed and was lost in the system's earliest eras.
  • The conclusion remains preliminary and requires deeper chemical and isotopic analysis.

Plants signal each other through chemicals and underground fungal networks

Researchers have documented how plants exchange information when attacked or stressed — no neurons, no sounds required.

  • Plants release volatile compounds when attacked, alerting neighbouring plants.
  • Underground fungal networks connect trees and enable nutrient transfer.
  • Researchers caution that "communication" in a strict sense is still to be proven.

Hubble photographs M88, a spiral galaxy slowly consumed by the Virgo Cluster

The Hubble Space Telescope has captured galaxy M88 in the grip of the Virgo Cluster, where powerful forces are steadily stripping away its ability to form new stars.

  • Spiral galaxy M88 is falling into the Virgo Cluster, gradually losing its interstellar gas.
  • Without gas reserves, M88 will be unable to form new stars — a process unfolding over hundreds of millions of years.
  • The Hubble image gives researchers a key reference for understanding how clusters quench star formation.
