Enzyme delivered in smaller package protects cells from radiation damage

...eliver MnSOD in this very small vector, we will be able to get this radioprotective enzyme more efficiently into all of the cells of the body and give patients receiving total body radiation for systemic cancers better long-term outcomes. This also has implications for the prophylactic protection of those...

Physicist cracks women's random but always lucky choice of X chromosome

...rwick physicist has uncovered how female cells are able to choose randomly between their two X chromosomes and why that choice is always lucky. Human males have both a X and a Y chromosome but females have two X chromosomes. This means that in an early stage in the development of a woman’s fertilised egg...
