War & Games & Wargames

Interesting article in the Times talking about the military’s use of war simulations to train soldiers. Free registration required.
More Than Just a Game, but How Close to Reality?
I say “war simulations” because that’s the term they used, but in many ways, these are the same games we play for fun. And the better our games get, as we layer on voice chat and team-based contests and persistent worlds, the closer we get to the realistic simulations the armed forces are striving for.

Reaaallly tiny wires

What a sci-fi world we’re living in, and most of us don’t even notice:

For years, scientists have tinkered with creating wires only nanometers — billionths of a meter — wide. A nanometer is to an inch what a small grape is to the whole planet.

Instead of building such wires by pouring metal down long tubes, some investigators instead are experimenting with biological materials that can arrange themselves into strings spontaneously — DNA and bacteria-killing viruses, for examples. These strands would then serve as the backbone for metal to attach onto, making wires.
