'Failed drug' could offer new approach to Epstein-Barr virus and resulting diseases
Researchers have found that the Epstein-Barr virus triggers infected cells to ramp up the production of an enzyme known as IDO1, a discovery that offers a promising starting point for putting the brakes on EBV.

Antibiotic ‘Velcro’ gives bacteria a sticky situation
A small antibiotic called plectasin uses an innovative mechanism to kill bacteria. By assembling into large structures, plectasin latches onto its target on the bacterial cell surface - scientists have now mapped how this bond is formed.

Mystery CRISPR unlocked: A new ally against antibiotic resistance?
CRISPR-Cas systems are bacterial adaptive immune systems that target and cut the nucleic acids (DNA/RNA) of invading genetic parasites like bacteriophages (phages); viruses that infect - and eventually kill - bacterial cells. They consist of two main components; the CRISPR array, which stores immune memory of past ...
