Invention: Microscopic Bio-Robot Slaves

Shrinking robots allows them to carry out ever more delicate tasks. But even the smallest built so far are too big to be able to, say, imprint microscopic, or even nanoscale, patterns onto microchips. Now Jan Liphardt, a physicist at the University of California, Berkeley, and colleagues, say it may be possible to create new species of slave bacteria to do the job instead. The idea is to create stripped-down versions of bacteria, with only enough of a genome to perform certain tasks - for...Full Story
