Films Of Mitchell And Kenyon Illuminate Lefties'Decline In Victorian E
By mining evidence from the classic films made by Mitchell and Kenyon, researchers have confirmed that the left-handed minority suffered something of a setback in Victorian England, at the beginning of the 20th century. In more recent times, lefties'numbers quickly rose again, the researchers report. Uranium Isotope Ratios Are Not Invariant, Researchers Show
For years, the ratio of uranium's two long-lived isotopes, U-235 and U-238, has been considered invariant, despite measurements made in the mid-1970s that hinted otherwise. Now, with improved precision from state-of-the-art instrumentation, researchers unequivocally show this ratio actually does vary significantly in Earth materials. Moments of Italian Cinema

Tollbooth Ventilation System Effective In Protecting Workers From Traf

Humans lacking the protein cardiac calsequestin (CASQ2) have a normal heartbeat when not exercising, but their heartbeat becomes irregular when they exercise, putting them at risk for sudden death. A new study in mice, by researchers from Vanderbilt University, has now shed light on why the lack of CASQ2 only triggers an irregular, and potentially fatal, heartbeat during exercise.
