Oct. 1, 2020 Experts have devised a simple way to glean more detailed information out of standard medical imaging scans. A research team made up of atomic physicists and nuclear medicine experts has designed a timer that can enable PET scanners to detect the oxygen concentration of tissues throughout patients' bodies. This upgrade to PET scanners may lead to a future of better cancer treatment by quickly ...

Sep. 30, 2020 The water crisis in Flint, Michigan, brought much-needed attention to the problem of potentially toxic metals being released from drinking water distribution pipes when water chemistry changes. Now, researcher have investigated how hexavalent chromium, known as Cr(VI), can form in drinking water when corroded cast iron pipes interact with residual disinfectant. Their findings could suggest new ...

Sep. 30, 2020 When the brightness of the star Betelgeuse dropped dramatically a few months ago, some observers suspected an impending supernova - a stellar explosion that could also cause damage on Earth. While Betelgeuse has returned to normal, physicists have found evidence of a supernova that exploded near the Earth around 2.5 million years ...

Sep. 29, 2020 A study of comet motions indicates that the Solar System has a second alignment plane. Analytical investigation of the orbits of long-period comets shows that the aphelia of the comets, the point where they are farthest from the Sun, tend to fall close to either the well-known ecliptic plane where the planets reside or a newly discovered 'empty ecliptic.' This has important implications for ...

Sep. 29, 2020 Researchers have now developed a new model that describes driving behavior on the basis of one underlying 'human' principle: managing the risk below a threshold level. This model can accurately predict human behavior during a wide range of driving tasks. In time, the model could be used in intelligent cars, to make them feel less ...
