Sci/Tech Tracking

• Bilboards using 'digital ink' developed (New York Times).


• Physicists have created blobs of gaseous plasma that can grow, replicate and communicate - fulfilling most of the traditional requirements for biological cells (New Scientist).
  • a few points in the article require some sort of justification
• Single atom laser. A research group at Caltech has successfully constructed a laser consisting of only one caesium atom. The emitted light is very weak but highly ordered, so such a device may be used to control a quantum computer (Story: PhysicsWeb; Discussion: Slashdot).
