Bisphenol S, a substitute for bisphenol A (BPA) in the plastic industry, shows the potential for increasing the aggressiveness of breast cancer through its behavior as an endocrine-disrupting chemical, a new study finds. The results, which tested BPS in human breast cancer cells, will be presented Saturday at ENDO 2017, the Endocrine Society’s 99th annual meeting in Orlando, Fla.

BPS is found in polycarbonate hard plastics, currency bills and thermal paper receipts as well as many products touted to be free of BPA, a known endocrine-disrupting chemical suspected of having multiple possible health risks...

Physicists are literally applying rocket science to the field of medical diagnostics. With a few key changes, the researchers used a noninvasive ultrasonic technique originally developed to detect microscopic flaws in solid fuel rockets to successfully detect cell stiffness changes associated with certain cancers and other diseases. The method uses sound waves to manipulate and probe cells.

The method combines a low-frequency ultrasonic wave to levitate the cells and confine them to a single layer within a fluid and a high-frequency ultrasonic wave to measure the cell’s stiffness. “An acoustic wave is a pressure wave so it travels as a wave of high and low pressure...
