Protein assassin: Scientists find that the unfolded end of a protein can kill E. coli-like bacteria selectively
When bacteria wage a turf war, some of the combatants have an extra weapon. Certain strains of the bacteria E. coli produce proteins that kill competing E. coli and other like microbes, and researchers from Newcastle Uni ...

Experiments explain why almost all multicellular organisms begin life as a single cell
Any multicellular animal, from a blue whale to a human being, poses a special difficulty for the theory of evolution. Most of the cells in its body will die without reproducing, and only a privileged few will ...
