Galaxies in groups lose hydrogen gas as they move through the intergalactic medium, making it harder for them to form stars.

Researchers have called for a reassessment of conservation values and attitudes surrounding introduced species following a study suggesting that large herbivores introduced to new regions are rewilding modern ecosystems.

After nearly a decade of intensive searching, an international team of astronomers has discovered the first star that varies its magnetic field like our own Sun.

The “BCool Project”, an international collaboration studying the dynamo generation of magnetic fields in cool stars, has been mapping the magnetic fields of a number of nearby stars using the Bernard Lyot Telescope in the French Pyrenees.

Regulating overfishing could protect Pacific coral reefs from strangulation by seaweed, according to new findings by a University of Queensland scientist.

“Pacific reefs are more vulnerable to increases in seaweed than we used to think,” said Professor Peter Mumby from the ARC Centre of Excellence for Coral Reef Studies and UQ’s School of Biological Sciences.

“Seaweeds tend to bloom when too many herbivorous fish are fished heavily or when agricultural fertilizers pollute rivers that run into the sea.
