Smaller, faster, cooler: graphene transistors show promise for practical analog signal processors, for magnetic memory devices, and for self-cooling electronic circuits.

‘Good Cholesterol’ nanoparticles are non-toxic and use the need of cancer cells for HDL cholesterol to deliver RNA molecules to silence the expression of cancer-promoting genes.

Phage-assisted continuous evolution of proteins is roughly a hundred times faster than conventional laboratory evolution of proteins, perhaps speeding the development of components for molecular machine systems.

Combined computational and experimental study shows molecules walking, hopping and flying across a surface; may lead to controlling molecular motion.

Porous silica nanoparticles covered with a lipid bilayer deliver large doses of drugs and kill cancer cells a million fold better than do simple liposomes.

The capabilities of scaffolded DNA origami procedures have been expanded to construct arbitrary, two- and three-dimensional shapes.

Real-time monitoring of atomic-force-microscope probes to adjust for wear may speed up and improve the accuracy of measurements and manipulations done with AFMs.

Willow Garage TurtleBot, an open source programmable robot with a 3D vision system, is available to preorder, starting at $500.

A high-resolution crystal structure of a small square made by self-assembly of RNA molecules reveals each corner of the square to have a unique structure.

David Hanson of Hanson Robotics argues that building humanlike robots will push the boundaries of several scientific and technical disciplines and prevent intelligent machines from becoming dangerous as they achieve true general intelligence.

Novel biodegradable nanoparticles destroy membranes of drug-resistant ‘superbugs’ without harming blood cell membranes.

Engineering both the pore size and chemical functionality of nanoporous materials affects both the secondary structure and the catalytic activity of the enzymes confined in the nanopores.

Research showing a toxic effect of silver nanoparticles on nitrogen-fixing bacteria in Arctic soil demonstrates the need for more research on nanoparticle environment, health, and safety.

Zyvex Technologies announced that its 54-foot boat named Piranha completed a rough-weather sea test near Puget Sound in the Pacific Ocean, demonstrating record fuel efficiency.
