Double-barreled
nano printing
The ability to precisely position tiny amounts
of DNA and other biological molecules is becoming increasingly
important in studying diseases, finding new drugs and
diagnosing illness. It is also key to the emerging practice
of making nanoscale devices from biomolecules...

Security
through obfuscation
In the world of computer security the name of
the game is access, or more specifically preventing access.
If you don't have the right password and/or certificate
and/or token, you can't get in the door...

Better
light switches
A pair of research papers promises improvements
in optical modulators, the light switches that encode
data into light beams for data communications. One could
lead to a 100-fold speed up of telecommunications and
the other provides a relatively inexpensive way of building
optical modulators into silicon computer chips...

Molecule
walks this way
Scientists making molecular-scale mechanical devices
have been mining the past for ideas. This makes sense
because things move much faster at the molecular scale.
The enhanced speed opens up new possibilities for mechanical
computation devices like the ancient abacus...

How
It Works: Data storage technologies
There are many possibilities for next generation
data storage: very large, extraordinary and ballistic
magnetoresistance; MEMS; near-field optics; holograms
and molecular switches. |
