The biggest challenge in a parasite's life is to move from one host to another. Intriguingly, many parasites have evolved the ability to manipulate the behavior of their hosts to improve their own survival -- sometimes even by direct...

Plants may not seem like they live the most exciting lives, but two new papers published this week point to different types of plants that are actually very cunning and manipulative. One, the parasitic dodder, steals both nutrients and...

Some parasites can hijack the brains of their victims and cause them to behave in strange ways, but how they do it, and do we humans need to be worried?

Your body usually does a great job defending you from all kinds of viruses, fungi, and bacteria. However, there are some pathogens out there that can hide from your immune system and stay dormant in your body, waiting for their...

Scientists have discovered viruses that infect viruses... virusception, if you will. Does this mean viruses qualify as life yet? Or are they still hanging out in the misfits drawer with sporks and Pluto?

Warning! This episode is a little gross… Between 1/3 and 1/2 of all life on earth is parasitic - and here are 4 of the creepiest parasites we know about.

There are fossils of viruses, of sorts, preserved in the DNA of the hosts that they've infected. Including you. This molecular fossil trail can help us understand where viruses came from, how they evolved and it can even help us tackle...

There's something surprising that helps determine how damaging a disease is: distance.
