Innovative sound-mapping software based on human hearing has been developed to help architects design out unwanted noise.
(PhysOrg.com) -- A team of researchers have used a mathematical equation to create a so called "rogue" wave; the giant kind that appear out of nowhere in the open ocean to topple ships and drown their crews. ...
Researchers at the Universities of Leeds and Chicago have uncovered an important mechanism behind the generation of astrophysical magnetic fields such as that of the Sun.

(PhysOrg.com) -- Socially learned behavior and belief are much better candidates than genetics to explain the self-sacrificing behavior we see among strangers in societies, from soldiers to blood donors to ...
Just as a terrestrial globe cannot be flattened without distorting the distances, it seemed impossible to visualize abstract mathematical objects called flat tori in ordinary three-dimensional space. However, ...
(PhysOrg.com) -- Living cells are bombarded with messages from the outside world -- hormones and other chemicals tell them to grow, migrate, die or do nothing. Inside the cell, complex signaling networks interpret these cues ...
