Ever since the late 19th century, physicists have known about a counterintuitive property of some electric circuits called negative resistance. Typically, increasing the voltage in a circuit causes the electric current to ...
A team of researchers at the U.S. National Institute for Standards and Technology has found that electron current flow direction produced by the photon-drag effect is dependent on the environment in which a metal is sitting. ...
When the Northern Spotted Owl was protected under the Endangered Species Act in 1990, the primary threat to the species was the loss of the old-growth forest it depends on. However, new research published in The Condor: Ornithological ...
