Meet The Nanomachines That Could Drive A Medical Revolution

Meet The Nanomachines That Could Drive A Medical Revolution

A group of physicists recently built the smallest engine ever created from just a single atom. Like any other engine it converts heat energy into movement – but it does so on a smaller scale than seen before. The atom is trapped in a cone of electromagnetic energy and lasers are used to heat it […]
