POPSFree-piston engine could be twice as fuel efficient as combustion engines In conventional internal combustion engines, multiple pistons are connected via rods to a crankshaft that, via the transmission, drives the wheels. Free-piston engines do away with the crankshaft: the pistons aren't connected to anything. Instead, two opposing pistons just shuttle back and forth inside a chamber. To generate electricity, the pistons could be equipped with rows of magnets that shuttle past metal coils to create an electrical current.

POPSHot New Steampunk Couture! Steampunk Couture is the result of a beautiful marriage of Neo-Victorian wear and our post-apocalyptic future. "Born wet and wide-eyed as a literary genre near the end of the last century, "steampunk" is just a word encompassing a litany of sins. The flagrant coupling of Victorian aesthetic, and phantastic technology. A dash of swashbuckle, a pinch of pathos, simmer until stirred or disturbed. Haberdashery sprung fully-formed from brandishing bustles, boots, and bodices (or monocles, spats, moustaches,) in shades of sepia, dashes of dun, blinks of black, coils of copper, illums of ivory, and jots of jewel-tone. Motifs meander from gearwheels to jacquard, stopping off at morbid, metallic, or romantic along the way. Accessorize with your favorite protective headwear. Let Kato, artist and craftist, escort you through her vogue's gallery of gamine garb. Tops, bottoms, and side-to-sides fit for adventure aloft

POPSGun stops bullet in mid air Atom sized bullets. The Military has tried to make a weapon that shoots magnetic projectiles, but so far no luck. They say the purpose of the coil gun is to try and weigh a neutrino, which are hard to catch. Apparently. Tritium, a Hydrogen isotope spits them out as they decay, but they are also hard to catch. Most Atoms are whizzing around, and holding them still isn't easy. They seem to have worked out how to do it. While the research can seem obscure sometimes there can be threads that lead the most unlikely places, some good some bad. It would be a shame if scientists ever stopped being surprised

POPSBetter Pictures of Proteins Because the radio-frequency signals that NMR spectroscopy relies on are very weak, large samples are needed to perform experiments. The instruments also require large, powerful magnets, which contribute to their size and expense. Hence, biochemists have had limited access to the machines. Traditional NMR uses coils to detect the radio-frequency signals produced by some atoms, including hydrogen and carbon, when they are exposed to a magnetic field. But the complex shape of the coils makes them difficult to further miniaturize. In contrast, the MIT researchers fabricated a highly sensitive NMR probe out of a flat strip of copper similar to the antennas in laptops and cell phones.
