The power to align water molecules is usually held by ice, which affects nearby water and encourages it to join the ice layer. But in the case of organisms in freezing habitats, a powerful antifreeze protein can convince water molecules to behave in ways that benefit the protein instead. In this week’s Journal of Chemical Physics, scientists are taking a closer look at the molecular structure of the antifreeze protein to understand how it works.
Hundreds of everyday items contain organophosphate ester (OPE) flame retardants and plasticizers. Some of these compounds make their way into the air, onto surfaces and even inside our bodies, with uncertain health effects.

Exposure to the widely used chemical bisphenol A (BPA) during pregnancy, even at levels lower than the regulated “safe” human exposure level, can lead to changes in circadian rhythms, according to a mice study to be presented Monday at ENDO 2019, the Endocrine Society’s annual meeting in New Orleans, La. The researchers report these changes may be a contributing factor in hyperactivity seen in BPA-exposed mice.
When you flush the toilet, you probably don’t think about the traces of the medicine and personal care products in your body that are winding up in sewage treatment plants, streams, rivers, lakes, bays and the ocean. But Rutgers scientists have found that bacteria in sewage treatment plants may be creating new contaminants that have not been evaluated for potential risks and may affect aquatic environments, according to a study in Environmental Toxicology and Chemistry.
Scientists at the University of Illinois at Chicago have developed a way to identify the beginning of every gene — known as a translation start site or a start codon — in bacterial cell DNA with a single experiment and, through this method, they have shown that an individual gene is capable of coding for more than one protein.
