Cell Phones, Cancer and the Dangers of Risk Perception

May 31, 2011, was a bad day for a society already wary of all sorts of risks from modern technology, a day of celebration for those who champion more concern about those risks, and a day that teaches important lessons about the messy subjective guesswork that goes into trying to make intelligent choices about risk in the first place, for policy makers or for you and me. The International Agency for Research on Cancer (IARC) says radiation from cell phones might cause cancer. OMG!!! Your phone is ringing! Now what?

Evidence Mounts for New Physics via Tevatron Particle Collider

A group of physicists working with data from a particle detector at the Tevatron collider announced last month that they had found something they could not explain. High-speed smash-ups between protons and their antimatter counterparts, observed by the Illinois site's CDF detector, appeared to yield a certain kind of package in unexpected abundance : a massive particle known as the W boson along with two jets of other particles. The CDF excess hinted at the existence of some unknown particle, an unidentified and possibly disruptive addition to the family of particles described by the long-reigning, exceptionally well-tested Standard Model of particle physics
