Organic electronic ratchets doing work
Researchers at Eindhoven University of Technology and the COBRA research institute in Eindhoven have succeeded in causing electron transport using an electronic 'ratchet'. This is the first time that usable powers have been generated at room temperature with a device of this kind. The finding opens the possibility of a new kind of wireless drive for microelectronic circuits.

Read moreHow do you cut a nanotube? Lots of compression
Researchers at Brown University and in Korea have described the dynamics behind cutting single-walled carbon nanotubes, cylindrical structures just 1/50,000th the width of a human hair. The tubes are compressed by potent sonic booms, causing them to buckle at certain points at helical, 90-degree angles. The finding could lead to better-quality nanotubes for potential use in automotive, electronics, optics and other fields.

The standard approach to cancer therapy today is to mix and match chemotherapy drugs in order to attack tumors in multiple ways. Now, two separate teams of investigators have demonstrated that using nanoparticles to deliver multiple drugs simultaneously can produce a synergistic effect that boosts the cell-killing ability of both drugs.

University of Utah physicists stored information for 112 seconds in what may become the world's tiniest computer memory: magnetic 'spins' in the centers or nuclei of atoms. Then the physicists retrieved and read the data electronically - a big step toward using the new kind of memory for both faster conventional and superfast quantum computers.
