A team of scientists has revealed how certain harmful bacteria drill into our cells to kill them. Their study shows how bacterial 'nanodrills' assemble themselves on the outer surfaces of our cells, and includes the first movie of how they then punch holes in the cells' outer membranes. The research, published today in the journal eLife, supports the development of new drugs that target this mechanism, which is implicated in serious diseases. The team brings together researchers from UCL, Birkbeck, University of London, the University of Leicester, and Monash University (Melbourne).

Pictured here are Dr. Turi King and Professor Kevin Schürer from the University of Leicester. International research led by the University of Leicester published in Nature Communications reveals:

• Analysis of all the available evidence confirms identity of King Richard III to the point of 99.999% (at its most conservative).
• Analysis of the mitochondrial DNA shows a match between Richard III and modern female-line relatives, Michael Ibsen and Wendy Duldig.
• The male line of descent is broken at one or more points in the line between Richard III and living male-line relatives descended from Henry Somerset, 5th Duke of Beaufort.
• King Richard was almost certainly blue-eyed and probably had blond hair at least during his childhood.
• The portrait which appears to most closely match the genetically-determined hair and eye colour is the Arched-Frame Portrait in the Society of Antiquaries.
