Ideas in 2004.

The New York Times Magazine published its 4th Annual Year in Ideas ("a compendium of ideas from A to Z").

You have to register in order to see this compendium and I tell you it is worth reading. Here are some interesting links:

- listening to cells noise or to keystrokes.
- cars that can be emotional.
- translucent concrete.
- acoustic freezer.
- plants detecting land mines.
- tattooed literature.
