WHAT=92S NEW Robert L. Park Friday, 29 Apr 2011 Washington, DC 1. ANTISCIENCE: THE ALPHA MAGNETIC SPECTROMETER. What happened to all the antimatter after the Big Bang? It's an important= =20 physics question: the theory is that the putative Higgs boson would=20 catalyze equal numbers of particles and anti-particles. If matter and=20 antimatter come into contact we get a Big Kablooey, so when antimatter is= =20 missing it's okay to worry. Sam Ting at MIT, who shared the 1976 Nobel=20 Prize with Burton Richter for discovering the J/Psi particle, now wants t= o=20 look for antimatter among cosmic rays, perhaps even determine what=20 direction they=92re coming from. So maybe 17 years ago he went to see Dan= =20 Goldin the NASA administrator, and proposed to hang his Alpha Magnetic=20 Spectrometer on the space station, bypassing the peer review system. It=20 was a big mistake but you tend to get away with that kind of stuff if=20 you're Sam Ting. But although he got around peer review, he landed in th= e=20 middle of a dying astronaut program, and it's been delay after delay=20 including the Columbia disaster. Ting had to appeal directly to Congress= =20 to get on the endeavor mission. The spectrometer should've been launched = on=20 its own platform, as far away from the astronaut program as possible. The= =20 AMS is now a massive $1.5 billion undertaking involving 500 scientists fr= om=20 56 institutions and 16 countries. . . WAIT, JUST IN! 12:28 Friday: NA= SA=20 has postponed today's launch of Endeavour citing a technical problem! Ev= en=20 if the problem is minor, we=92re looking at a three day delay. Time is=20 running out for the shuttle -- and for the AMS. 2. MONARCHY: IS THERE NO CURE FOR THIS AFFLICTION? In seeking news on the Endeavor non-launch I found the US news media almo= st=20 totally focused on the royal wedding. It particularly pains me to watch=20 Americans fawning over the monarchy we fought a war to get rid of, and if= I=20 hear "fairytale" mentioned one more time I may become violent. =20 3. NUCLEAR POWER: IN SPITE OF FUKUSHIMA WE STILL NEED IT. In fact, we need nuclear power more than ever. However, the Fukushima=20 Daiichi plant in Japan involves not only damage to three reactors, but al= so=20 the loss of cooling water in at least one pool of spent radioactive fuel.= =20 And according to Matthew Wald in today's New York Times that pool was not= =20 loaded nearly as heavily as pools at similar reactors in the United=20 States. According to an MIT study, the Fukushima storage-pool problem=20 places more emphasis on getting the geological repository, i.e. Yucca=20 Mountain, up and running. Engineers involved in the Yucca Mountain proje= ct=20 say that even if Congress could be persuaded to authorize money for a=20 permanent repository, it would be a few years before the government could= =20 decide whether the site was suitable and many more years before it could=20 absorb a major fraction of the waste now sitting at reactor sites,=20 http://bobpark.physics.umd.edu/WN01/wn113001.html .
