Polynyas are patches of open water surrounded by sea ice, where heat and moisture can pass freely between the ocean and atmosphere. In August 2024, a vast polynya opened up in Breid Bay, off the coast of East Antarctica, in the depths of winter. The region had stayed ice-covered

Polynyas are patches of open water surrounded by sea ice, where heat and moisture can pass freely between the ocean and atmosphere. In August 2024, a vast polynya opened up in Breid Bay, off the coast of East Antarctica, in the depths of winter. The region had stayed ice-covered at this time of year ever since satellite records began in 1979.

Newly discovered antiviral system in bacteria is 'strangest of its kind'

Researchers at Gladstone Institutes have uncovered an unusual bacterial immune system that operates in reverse of known defenses. The discovery, published in Molecular Cell, details the mechanics of "type VI retrons"—a counterintuitive class of bacterial defenses. More than just
