Measured steps advance the understanding of molecular motors.
The origin of motion within our bodies has been traced to certain molecules that function as tiny motors. Recent experiments have been able to study individual motor molecules and to measure the size of the discrete, unidirectional steps they take and the force they exert. Chromium surrogate Sun confirms that solar neutrinos really are missing. As we hear early reports of neutrino oscillation in an accelerator beam, an experiment with a surrogate Sun lends credence and clarity to the solar neutrino puzzle, the oldest of the anomalies that point to exotic neutrino metamorphosis. Because of a Clinton Administration initiative, attention again focuses on designing more efficient automobiles.
