Researchers convert microbubbles to even smaller nanobubbles using ultrasound

A team of researchers is developing a new form of microbubble delivery, deploying ultrasound to implode the bubbles into several smaller nanobubbles that can cross biological barriers due to their size and release the payloads within the target area.

Bacteria deliver molecule to gut to suppress hunger and ward off weight gain

To transport a hunger-suppressing molecule to the gut as a treatment for obesity, researchers at Vanderbilt University have put bacteria to work. The bacteria become lodged in the digestive system and release the lipid for up to a year at a time, altering the gut microbiome to stave off weight-related problems like diabetes and heart disease.
