+ - Bacteria-Killing Viruses Wield an Iron Spike->

Submitted by sciencehabit
sciencehabit (1205606) writes "Scientists have long known that a group of viruses called bacteriophages have a knack for infiltrating bacteria and that some begin their attack with a protein spike. But the tip of this spike is so small that no one knew what it was made of or exactly how it worked. Now a team of researchers has found a single iron atom at the head of the spike, a discovery that suggests phages enter bacteria in a different way than surmised."
