A team of researchers at Technion-Israel Institute of Technology has conducted the first experimental observation of the branched flow of spatially incoherent light—in this case, using liquid dish soap. In their paper published ...
As a human fetus develops, its heart has to keep pace with the new body's ever-growing demands. Much of this is controlled by following genetic blueprints, but the embryonic heart also matures in response to the intense stresses ...
