Scientists reveal the surprising origins of Earth's largest oceanic engine
Imperial College London
Published: 7 April 2026
Climate simulations show the Antarctic Circumpolar Current formed through glaciation and wind changes rather than ocean gateway openings alone, fundamentally changing our understanding of how Antarctica's ice sheet and this giant current co-evolved.

Hawaiian bobtail squid depend on bacterial partner for healthy development
University of Hawaii at Manoa
Published: 2 April 2026
Researchers discovered that a single bacterial protein (SypC) from Vibrio fischeri is essential for the Hawaiian bobtail squid light organ to develop correctly, with the squid immune cells helping deliver bacterial packets to the organ.
