New research from UTMB scientists found a newer chemical used to replace BPA called bisphenol S, or BPS, acts similarly to hormone-disrupting BPA. Appearing online in the journal Environmental Health Perspectives, the new animal study finds BPS behaves very similarly to BPA, a chemical that throws off the body's natural signaling of estrogen, which is a bodily function both men and women need to be healthy. "[T]his study shows us that very low levels of BPS can disrupt natural estrogen hormone actions in ways similar to what we see with BPA,” said UTMB’s Cheryl Watson. “That’s a real cause for concern.” The news also appears in Science Codex, Medcompare and Rodale, among other outlets.
