By comparing the biology of jawless and jawed vertebrates, researchers can gain insight into the evolutionary origins of features that define vertebrate animals including humans, how differences in gene expression contribute to key differences in the body plan, and what the common ancestor of all vertebrates looked like.

Lampreys possess a ‘jaw-dropping’ evolutionary origin

Invasive, blood-sucking fish ‘may hold the key to understanding where we came from’

One of just two vertebrates without a jaw, sea lampreys that are wreaking havoc in Midwestern fisheries are simultaneously helping scientists understand the origins of two important

Deep-ocean floor produces its own ‘dark oxygen’

New study finds metallic minerals act as geobatteries to split water

An international team of researchers, including a Northwestern University chemist, has discovered that metallic minerals on the deep-ocean floor produce oxygen — 13,000 feet below the surface.

The surprising …

Brain’s structure hangs in ‘a delicate balance’

New finding appears to be universal across insects, mammals and humans

When a magnet is heated up, it reaches a critical point where it loses magnetization. Called “criticality,” this point of high complexity is reached when a physical object is …
