An anonymous reader writes: At this year’s Tour de France, thermal cameras and various other tools will be used to detect “mechanical doping.” The image tests can be done anywhere and their locations will not be publicized, according to officials. NPR reports: “As far back as at least 2010, accusations have flown that elite cyclists were turning in superhuman performances with the help of motors that are hidden inside their bike’s seat tube. Commercial versions of such devices can provide a steady power stream of around 200 watts — the lower range of a pro cyclist’s average output in a stage race. They can also be set to assist riders automatically if their pedaling cadence falls below a certain threshold. Tour de France officials explain how the detection system will work: ‘Developed by the CEA (the French Atomic Energy Commission), the method consists of using a thermal imaging camera capable of detecting mechanical anomalies on the riders’ bikes. The checks can be made in the race and on the side of the roads.'”

An anonymous reader writes from a report via ScienceAlert: Physicists have confirmed the existence of pear-shaped nuclei, which challenges the fundamental theories of physics that explain our Universe. “We’ve found these nuclei literally point towards a direction in space. This relates to a direction in time, providing there’s a well-defined direction in time and we will always travel from past to present,” Marcus Scheck from the University of the West of Scotland told Kenneth MacDonald at BBC News. Until recently, it was generally accepted that nuclei of atoms could only be one of three shapes: spherical, discus, or rugby ball. The first discovery of a pear-shaped nucleus was back in 2013, when physicists at CERN discovered isotope Radium-224. Now, that find has been confirmed by a second study, which shows that the nucleus of the isotope Barium-144 is also asymmetrical and pear-shaped. In regard to time travel, Scheck says that this uneven distribution of mass and charge caused Barium-144’s nucleus to “point” in a certain direction in spacetime, and this bias could explain why time seems to only want to go from past to present, and not backwards, even if the laws of physics don’t care which way it goes.
