Episode notes

Researchers have found and identified bacteria that could help break down some of the forever chemicals accumulating around the world. The researchers obtained microb-rich sludge from a local sewage treatment plant and exposed it to a variety of chlorine-bearing PFAS molecules. They found that after the bacteria first removed the chlorine, they could then remove almost 80% of the fluorine atoms. Now scientists have used clever chemistry to identify the precise combination of ingredients needed to ensure that gummies keep their chew.

00:46 An AI that predicts gene interactions

Mapping the network of genes that control cellular processes can be difficult to do when gene-expression data is sparse, such as in rare diseases or those affecting tissues that are hard to clinically sample. To overcome this, a team has developed an artificial intelligence system trained on a large, general dataset, and used it to make predictions about gene interactions in data-limited situations. As a test-case they look at the heart condition cardiomyopathy, and show that the system can identify potential interactions that could represent new therapeutic targets.
