Researchers say the Pacific golden sweeper cannot make its own luciferase and instead acquires the light-producing protein from tiny crustaceans it eats.

Researchers say iron-containing immune cells in pigeon livers may help explain how birds detect Earth’s magnetic field, offering a new candidate mechanism for one of animal navigation’s longest-running mysteries.

Researchers working in the Democratic Republic of Congo have documented shellear fish scaling a near-vertical waterfall, revealing a rare migration strategy driven by anatomy, humidity, and persistence.

A new Science paper reports that HNF1B integrates signals in a feed-forward loop associated with kidney disease progression, highlighting a regulatory mechanism for further study.

New research highlighted by Phys.org examines how poison frogs developed a potent chemical defense system over time, offering a closer look at the evolutionary path behind one of nature’s most famous warning signals.

A new Medical Xpress essay challenges the idea of the human body as a perfectly engineered machine, arguing instead that anatomy reflects evolutionary compromise.

A report highlighted a tiny shellear fish from Congo that was said to climb rocks 50 feet high in about 10 hours, an unusual feat that stands out for both biology and bio-inspired engineering

A newly published Science paper points to a machine learning approach aimed at discovering prokaryotic immune systems, underscoring how AI methods are being applied to one of biology’s most active frontiers.

Researchers studying octopus mating found that the male hectocotylus is not just a reproductive appendage but also a sensory organ able to chemically detect the target site inside the female.

A Science study reveals that unrelated animal species independently evolved nearly identical molecular mimics of the pain-causing peptide bradykinin as a defensive weapon.
