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," ...

Next frontier in bacterial engineering

From bacteria-made insulin that obviates the use of animal pancreases to a better understanding of infectious diseases and improved treatments, genetic engineering of bacteria has redefined modern medicine. Yet, serious limitations ...

The paradox of dormancy: Why sleep when you can eat?

Why do predators sometimes lay dormant eggs, which are hardy, but take a long time to hatch and are expensive to produce? That is the question that researchers from Singapore University of Technology and Design (SUTD) set ...

Scientists develop 'Twitter' for cells

Computational biologists led by Prof. Yvan Saeys (VIB-UGent Center for Inflammation Research) developed a new bioinformatics method to better study communication between cells. This method, called NicheNet, helps researchers ...
