20. Pentagon says lasers and other technology have led to low Medal of Honor count; lawmaker disagrees August 05, 2009 The Medal of Honor has been awarded 3,467 times since the Civil War. Almost half — 1,522 — were awarded in that conflict alone. The next highest tally came from World War II — 464. In the Vietnam War, 244 were awarded. For some veterans and members of Congress, that last number simply doesn't add up. They question how so few Medals of Honor — all awarded posthumously — could be bestowed for two wars of such magnitude and duration. Pentagon officials say the nature of war has changed. Laser-guided missiles destroy enemy positions without putting soldiers in harm's way. Insurgents... (read more) Author: Shane Ennerson

24. Miniaturized lasers can emit quantum light August 05, 2009 For more than 100 years it has been known that light comes in small packages, the so-called photons. The discovery of this quantization of the light field has opened up a new field of physics - quantum optics. In the sixties one of its pioneers, the Nobel Prize winner Roy Glauber, suggested to characterize light sources according to the sequence of their emitted photons. But the realization of this idea has been very limited up to now. In modern lasers the light emission can take place within a picosecond, a 1000 times faster than has ever been detected before in photon sequence measurements. ... (read more) Author: Shane Ennerson
