logic digitizes cells
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...

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...

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...

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.
