Nano-Shells Teach Bone how to Repair Itself

Edited by Senior Editor Michael Anderson


Scientists at the University of Michigan (Ann Arbor, MI) have developed a polymer sphere that delivers a molecule to bone wounds that tells cells already at the injury site to repair the damage.Using the polymer sphere to introduce the microRNA molecule into cells elevates the job of existing cells to that of injury repair by instructing the cells’ healing and bone-building mechanisms to switch on, said Peter Ma, professor of dentistry and lead researcher on the project.

A Real-World ‘Invisibility Cloak’? Research Teams See Progress

Edited By Senior Editor Michael Anderson


For decades—since the first season of the original Star Trek series, at least—the world has wondered if something like a “cloaking device” to create functional invisibility would ever be feasible. Now, after a long wait, real progress was reported from two separate sources within a week of each other. Full Article

Tech Front: Li-ion Battery Tech Leads to Hydrogen Production

Edited by Senior Editor Michael C. Anderson


Developers of electric cars that used lithium-ion batteries are racing the champions of hydrogen-fueled vehicles to see which will succeed the greenhouse gas-producing gasoline-powered internal combustion engine. They’ve been racing in different directions—until now: Scientists at Stanford University have created a low-voltage, low-cost “water splitter” that uses a single catalyst to continuously produce both hydrogen and oxygen from water.
