New technique reveals switches in RNA

Scientists at the University of Groningen (The Netherlands), in collaboration with colleagues from the University of Torino (Italy), have developed a method to visualize and quantify alternative structures of RNA molecules. ...

Metabolic mutations help bacteria resist drug treatment

Bacteria have many ways to evade the antibiotics that we use against them. Each year, at least 2.8 million people in the United States develop an antibiotic-resistant infection, and more than 35,000 people die from such infections, ...
