Right now, while you are reading this article, billions of your cells are busy replicating your DNA information. Although molecules are smaller than the wavelength of light, and thus we have no way to directly observe them, can we still somehow visualize these processes?

Biomedical animator and MacArthur Foundation nominee Drew Berry of the Walter and Eliza Hall Institute of Medical Research presents in a recent TEDx talk of less than 9 minutes, the state-of-the-art in molecular animation. He shows an accurate representation of the actual biological processes that happen on molecular scale, even at the correct speed2.

Next to a movie that originates back from around 2003 that focuses on the replication of DNA, he also shows a newer version that has been accomplished through "updated science, updated technology", revealing how DNA mitosis through a nifty process of some quite 'mechanical' signal broadcasting system. At the end, he highlights the processes behind a malaria infection of a human child via a mosquito bite, through invasion of cellular tissues including the liver and blood. malaria spreads in your blood.

More biological visualization videos can for instance be found at WEHI-TV and Harvard's BioVisions Lab.
