The Way Up and The Way Down

by Elio
I admit to not having paid much attention to the mechanisms that plants and animals use to stand up straight, or, in the case of plants, also to descend into the soil.

Flagellar Motors: How a Bacterium Shakes its Groove Thing

by Mike Delmont
Many things in our lives are so common that we take them for granted, forgetting their remarkable complexity. These can range from the social microbiology involved in cheese making, to the physics behind the internal combustion engine, or the anato­my/physiology behind taking a couple of steps Read more →
