A nanoparticle spray can turn regular paper into superpaper, rendering it waterproof, antimicrobial, magnetic and probably very expensive. Who said paper was an old technology?
Scientists at the Istituto Italiano di Tecnologia in Genoa, Italy, developed a process to cover any cellulose fiber, like paper or fabric, with a reactive coating. It involves combining the fiber molecules with a nanoparticle solution, creating a polymer matrix.
The world’s smallest magnetic data storage unit is made of just 12 atoms, squeezing an entire byte into just 96 atoms, a significant shrinkage in the world of information storage. It’s not a quantum computer, but it’s a computer storage unit at the quantum scale. By contrast, modern hard disk drives use about a million atoms to store a single bit, and a half billion atoms per byte.
Electron-free magnetic microprocessors would use 1 million times less energy per flop than today’s computers, according to researchers at the University of California-Berkeley. They would be so efficient, they would consume the least amount of energy allowed by the second law of thermodynamics.
Forget rockets. All you need to launch a satellite is a sled and a giant magnetic slingshot

Astronauts are trained to withstand as much as nine times the force of gravity. (Three Gs, by comparison, could make the average guy pass out.) But even the toughest among them fall out of the running when it comes to a launch concept from a small civilian company in Goleta, California. To survive the ride on Launchpoint Technologies´s invention, the payload has to be able to survive a brain-splattering 10,000 Gs.
The design calls for a high-speed accelerator that whips a projectile as heavy as 220 pounds around a circular 1.5-mile-radius vacuum tunnel.
