Hijacking bacteria's natural defences to trap and reveal pathogens

Bad bacteria could soon have no place left to hide, thanks to new materials that turn the cell’s own defences against them.

Scientists at The University of Nottingham and GSK Consumer Healthcare have developed a technique that could locate the potential source of an infection by hijacking the... Read More

Bespoke microbiome therapy to manage plant diseases

In this paper we describe the perspective of following the achievements in medicine, where gut microbiome transplants are proving to be a powerful method to overcome several gastrointestinal disorders and many other physiological problems, to possible solve diseases in plants. There is strong si... Read More
