Scientists at the University of New South Wales in Australia have developed a method to produce human blood stem cell precursors from human pluripotent stem cells. The method may have use in treating cancer patients who require high doses of such blood stem cells to help replenish endogenous populations that have been destroyed by chemotherapy.

Researchers at the City University of Hong Kong have developed a magnetic soft millirobot that can grab and release objects, and move around by rolling. The device can be controlled using magnetic fields, and consists of a biodegradable gelatin and iron oxide microparticles.
