Polio immunizers murdered by Taliban

Maryn McKenna summarizes what we know about the murder of six people working as polio vaccinators who were targeted in three separate coordinated attacks in Pakistan. This comes in the wake of the CIA ruse in 2011 who used an immunization campaign to find Osama Bin Laden. Read More

Toxoplasmosis: A T.Gondii Host-pathogen interactome

This parasite interacts with many host proteins and modifies the expression of many more genes creating an interactome with almost 3000 links. In addition it exchanges substrates and metabolites with the host, modifying many biochemical parameters. T.Gondii disrupts multiple signalling network... Read More

Single-minded Mission

Viruses exist for one purpose only: to reproduce. To do that, they have to take over the reproductive machinery of suitable host cells.


Upon landing on an appropriate host cell, a virus gets its genetic material inside the cell either by tricking the host cell to pull it inside, like ... Read More
