Researchers create a microscopic game of ‘Pac-Man’
Scientists capture images of molecules forming atomic bonds
For most of us, molecular bonding only really exists as a classroom concept. Some scientists at Lawrence Berkeley National Laboratory can now claim more tangible knowledge, however: they're the first to have taken truly clear snapshots of bonding in progress. While trying to create graphene nanostructures and observe them with an atomic force microscope, a lab team spotted molecules forming their individual, atom-level links during a chemical reaction. The resulting shots were nearly textbook material, too -- as the molecules were neatly placed on a flat surface, the researchers identified the order and nature of each bond. While the images will only be immediately useful for the nanostructure research at hand, they may add a welcome dash of reality to future chemistry lessons.

Georgia Tech models swimming, cargo-carrying nanobots
The nanobot war is escalating. Not content to let Penn State's nanospiders win the day, Georgia Tech has answered back with a noticeably less creepy blood-swimming robot model of its own, whose look is more that of a fish than any arachnid this time around. It still uses material changes to exert movement -- here exposing hydrogels to electricity, heat, light or magnetism -- but Georgia Tech's method steers the 10-micron trooper to its destination through far more innocuous-sounding flaps. Researchers' goals are still as benign as ever, with the goal either to deliver drugs or to build minuscule structures piece-by-piece. The catch is that rather important mention of a "model" from earlier: Georgia Tech only has a scientifically viable design to work from and needs someone to build it. Should someone step up, there's a world of potential from schools of tiny swimmers targeting exactly what ails us.
