A mysterious oceanic barrier is stopping some deep-sea jellyfish in the Arctic from reaching the Atlantic Ocean, a new study has found. The animals, members of the jellyfish subspecies Botrynema brucei ellinorae, inhabit depths between 3,300 and 6,600 feet (1,000 to 2,000 meters) and can be divided into two groups based on whether individual specimens have a knob on their …

Promoting pyroptosis — an inflammatory form of programmed cell death — has become a promising treatment strategy for cancer. In research published in The FASEB Journal, investigators purified a long-chain sugar molecule, or exopolysaccharide, from deep-sea bacteria and demonstrated that it triggers pyroptosis to inhibit tumor growth. The compound, called EPS3.9, consists of mannose and glucose and is produced by …

In an exciting breakthrough, scientists from Fisheries and Oceans Canada made an unexpected discovery off the coast of Vancouver Island—thousands of giant, living eggs at the summit of an active underwater volcano. This remarkable find not only changes our understanding of this remote region but also reveals how volcanic heat can be harnessed by marine life in extraordinary ways. A …

A new discovery in one of the most remote and extreme parts of the ocean is challenging our understanding of life at incredible depths. Deep beneath the Pacific Ocean, at nearly 8,000 meters, scientists have found an organism that defies expectations. For decades, this dark and hostile environment was thought to harbor only scavengers, but recent findings suggest there is …
