Mystery molecule in bacteria is revealed to be a guard

Peculiar hybrid structures called retrons that are half RNA, half single-strand DNA are found in many species of bacteria. Since their discovery around 35 years ago, researchers have learned how to use retrons for producing ...

Sound waves replace human hands in petri dish experiments

Mechanical engineers at Duke University have demonstrated a set of prototypes for manipulating particles and cells in a Petri dish using sound waves. The devices, known in the scientific community as "acoustic tweezers," ...
