Tiny DNA rotor lets microscopes track gene transcription one base pair at a time

Scientists often describe life as a series of chemical reactions. Pallav Kosuri, Ph.D., describes life as movement. Chemical ...

DNA origami nanosyringe actively transports molecules into synthetic cells

Transporting molecules across biological membranes is essential for life. In nature, this can occur through passive transport, known as diffusion. "Biological systems often use mechanical motion to ...
