3D Microscopes: To boldly go…

Learn about the potential applications of 3D printing, via the use of this surgical tool; a biopen that prints a gel laden with stem cells.

Aerogels are the world's lightest (least dense) solids. They are also excellent thermal insulators and have been used in numerous Mars missions and the Stardust comet particle-return mission. The focus of this video is silica aerogels, though graphene aerogels are now technically the lightest.

This video captures the fascinating final moments of a single-celled organism, which belongs to the genus Blepharisma. Watch as the protozoa's membrane breaks down and its organelles spill out.
