The unusual pattern of radio waves dubbed the USS Jellyfish tells a story of intergalactic gas meeting black hole by-products.

Paleontology

Scientists are arguing over the identity of a fossilized 10-armed creature

An ancient cephalopod fossil may be the oldest ancestor of octopuses, but the interpretation hinges on the identification of one feature.

Animals

Dazzling underwater photos capture new views and scientific detail of fish larvae

Lab specimens of fish larvae are often mangled and bleached. Divers and researchers have partnered to study their rich colors and intricate bodies.

Animals

Jellyfish snot can sting swimmers who never touch the animal

Researchers have found mobile cellular blobs coated with stinging cells in mucus from a jellyfish that sits upside-down on the seafloor.

Life

A distant cousin of jellyfish may survive without working mitochondria

A tiny creature that parasitizes salmon is the first known multicellular eukaryote without a mitochondrial genome, a hallmark of complex life.
