In Physics of Fluids, scientists report calculations with a model of a conical-shaped root canal inside a tooth. A crucial step in this common dental procedure is irrigation, or rinsing, of the root canal cavity with an antibacterial solution, and the researchers used computational fluid dynamics to determine the effect of temperature on the cleaning efficiency: Higher temperatures can, to a point, improve cleansing, but this benefit falls off if the temperature gets too high.
The American Institute of Physics and the American Physical Society announce Svetlana Jitomirskaya, from the University of California, Irvine, as the recipient of the 2020 Dannie Heineman Prize for Mathematical Physics. The award is given annually to recognize significant contributions to the field. Jitomirskaya is the second woman to receive this award.
