How do we reduce toxic byproducts of washing lettuce? Chlorine sanitizers used in the produce industry makes some byproducts in spent wash water that are not super healthy for us. These researchers are still searching for the best strategy to reduce toxic byproducts of chlorinated lettuce sanitizers using a technique called pre-oxidation.

Essential oil-coated fabrics repel bacteria and mosquitoes Findings show significant antimicrobial and potential mosquito repellent properties for fabrics treated with a microemulsion finish of lemon and litsea essential oils. It washes off, but researchers are working on a way to make it stick better.

A new way to detect ET life using chemical profiles Rather than detecting one chemical at a time, scientists taught machine learning algorithms what different mixtures of compounds from living and non-living sources “look like” to chemical analyzers. The computer then used those fingerprints to correctly identify living and non-living samples in the lab!
