(Phys.org) -- Most animals move around by using their appendages, such as legs, wings, or fins. But a few exceptional creatures employ rolling as a mode of locomotion. Included in this group are rolling salamanders, spiders, ...
(Phys.org) -- The famous physicist Niels Bohr first conceived of the notion of quantum jumps, or quantum leaps, in 1913. Bohr understood quantum jumps as objective events in which an atom emits or absorbs a photon, causing ...
(PhysOrg.com) -- For more than two decades, scientists have been "watching" electrons in atoms make the jump between energy levels in real time. "Atoms have energy levels, and when electrons 'jump' from one level to another, ...
It's a question that keeps some scientists awake at night: Do spiders sleep?

A trio of researchers, two with the Royal Veterinary College, the other the University of Portsmouth, has found evidence that suggests that the ilio-sacral joint in frogs evolved after they started jumping. In their paper ...
Picture a grasshopper landing randomly on a lawn of fixed area. If it then jumps a certain distance in a random direction, what shape should the lawn be to maximise the chance that the grasshopper stays on the lawn after ...
