Australian scientists have investigated the forces that create some of the world’s densest and coldest water. Although Antarctic Bottom Water is known in just four remote locations, its flow impacts weather patterns all around the world.

Billions of years ago, a day on Earth did not last 24 hours. New research suggests that for about one billion years, each day stayed fixed at roughly 19 hours because of a balance between the oceans, the atmosphere, and the pull of the…

Heart disease is the leading cause of death in the United States.

Since researchers first established the link between diet, cholesterol and heart disease in the 1950s, risk for heart disease has been partly assessed based on a patient’s…

For five years now, Briefing readers have eagerly awaited Fridays for a chance to put their penguin-hunting skills to the test. Each week, Leif Penguinson, a Rockhopper penguin, travels to…

Distinct ligands for the same G-protein coupled receptor (GPCR) activate intracellular signaling partners to varying extents, but the molecular mechanisms driving these differences remain elusive. Hypothesizing that such differences in signaling…

The nascent polypeptide-associated complex (NAC) is a conserved ribosome-bound factor with essential yet incompletely understood roles in protein biogenesis¹. Here, we show that NAC is a multifaceted regulator that coordinates translation…

In a rainforest in Panama, a baby hummingbird scared off a wasp by behaving like a poisonous caterpillar. That tiny bird, a white-necked jacobin (Florisuga mellivora), has given scientists the first clear record of caterpillar-style mimicry in a…

Until now, accurately dating fossils has been one of paleontology’s major challenges. Most dating methods rely on surrounding volcanic materials such as zircon-bearing ash, which are absent in many fossil-rich formations. When those aren’t…
