This photomicrograph depicts a Treponema pallidum bacterium, a spirochete 5 - 15 micrometers in length, which is the causative agent of syphilis.
Syphilis, is passed from person to person through direct contact with a syphilis sore. Sores occur mainly on the external genitals, vagina, anus, or ... Read More
By adding some art to his “Fundamentals of Microbiology” science course at the University of Waterloo, Biology professor Josh Neufeld has found a way to engage his students with the topic in a fun and creative way.
BIOL 140, explains Neufeld, is a large introductory course divided across thre... Read More

Like a major city, our cells use a complex transportation network to deliver molecular goods to different destinations. A protein called kinesin (blue) is in charge of moving cargo around inside cells and helping them divide. It's powered by biological fuel called ATP (bright yellow) as it scoot... Read More
