Protein logic digitizes cells
Brain researchers often use the analogy of brain as computer to frame their work. As it turns out, the analogy is also handy for examining the complex biochemical interactions inside individual cells...

Spray-on solar cell manufacturing
Researchers from Delft University of Technology in the Netherlands have developed a low-cost spray-on manufacturing technique for making solar cells...

Biochip spots cancer signs
The practice of chemically "functionalizing" carbon nanotubes and semiconductor nanowires by attaching DNA or other biomolecules to them has led to prototype biochips that can detect bacteria, viruses, specific types of DNA, or particular proteins molecules...

Plasma pen to fight plaque
In the not too distant future, your dental hygienist might stick what looks like a small blowtorch into your mouth. It shouldn't hurt, though, because the device will be emitting cold plasma rather than hot flame...

Bits and pieces
High-speed organic memory, current altering salt, and measuring how surfaces change atoms.


View from the High Ground:
Georgia Tech's Ronald Arkin

The economics of labor, making robots as reliable as cars, getting robots to trust people, biorobotics, finding the boundaries of intimate relationships with robots, how much to let robots manipulate people, giving robots a conscience, robots as humane soldiers and The Butlerian Jihad.

How It Works: Two schools of cryptography
There are two approaches to securing information: extremely difficult mathematical problems and the randomness of nature. Both count on the limits of technology.
