From New Scientist:

The video above captures the moment when a malaria parasite invades a human red blood cell – the first time the event has been caught in moving pictures.

The Plasmodium parasite responsible for malaria is transmitted by the bite of infected mosquitoes, and is thought to kill almost 1 million people worldwide each year.

Jake Baum at the Walter and Eliza Hall Institute of Medical Research in Melbourne, Australia, and colleagues used transmission electron microscopy and 3D immuno-fluorescence microscopy to record a series of still images during the 30-second-long invasion, and combined them into a movie.

Damn nature, etc.
