(Phys.org)—Microtubules – tubular polymers of tubulin (a globular protein) that are a component of the cytoskeleton found throughout cell cytoplasm – are involved in a range of cellular functions, including the movement ...
(Phys.org) —Maxwell's demon, the hypothetical doorman that controls how particles travel between two chambers in an attempt to decrease entropy, is at its heart a feedback-controlled system. The demon makes measurements ...
An international team of investigators from Brazil, Scotland and Germany is expanding the research base on the brain's complex suite of connections known as neural networks using computer simulations and a technique called ...

In the original Maxwell's demon thought experiment, a demon makes continuous measurements on a system of hot and cold reservoirs, building up a thermal gradient that can later be used to perform work. As the demon's measurements ...
(Phys.org)—On the surface, ants and the Internet don't seem to have much in common. But two Stanford researchers have discovered that a species of harvester ants determine how many foragers to send out of the nest in much ...
