Teleporting Matter’s Traits: Beaming information quantum-style
Physicists have transferred a quantum state from one atom to another by manipulating a mysterious, atom-to-atom quantum link called entanglement.

Letters from the June 19, 2004, issue of Science News
Scan or scam? Using laser technology that has an apparent resolution of only about half a centimeter is somewhat laughable (“Laser scanners map rock art,” SN: 4/3/04, p. 222: Laser scanners map rock art). I also wondered whether the “fresh coat of desert varnish” was an April fool joke. Actually, I really look forward to […]

Does it really take a team of scientists running computer simulations to come up with the common sense that the greater the common surface area of two objects that touch, the more efficient the stacking? The closer objects are to being flat, the more efficiently they will stack. Hence ellipses will, of course, stack more […]
