A gene, which allows yeast cell to reset their age and double their lifespan, has been found by biologists at MIT. Human…
Welcome to If I had a blank cheque I’d … a new series in which leading researchers reveal what they could do in their discipline if money were no object. Today we hear from Malcolm Walter, professor of…
The genomes of the recent German E. coli outbreak have revealed crucial insights into the origins of this deadly strain. The bacteria was found in German bean sprouts but it didn’t originate from the gut…
Malaria parasites are able to adapt their growth rate to render anti-malarial drugs useless, according to new research by Australian scientists. More than 200 million people are infected annually with…
