WHAT=92S NEW Robert L. Park Friday, 25 Feb 2011 Washington, DC 1. SELLING SCIENCE: HOW THE TEMPLETON FOUNDATION BOUGHT THE AAAS. Last week in item 2, I made a serious error. The final sentence said, "T= he=20 AAAS later backed out, but it serves to remind us that, however obtained,= a=20 disproportionate share of the world's wealth, even in the hands of the we= ll- intentioned, threatens us all." The sentiment was right-on, but the AAAS= =20 had not backed out of the deal with Templeton; the terms were merely=20 altered. It is now called the AAAS Dialogue on Science, Ethics, and=20 Religion. I have been a Fellow of the AAAS for most of my adult life and= =20 have no plans to resign. I will gladly work with other AAAS scientists t= o=20 terminate this program. Science, with its insistence on openness and=20 physical evidence, has a responsibility to inform the world of what has=20 been learned even when people would prefer not to hear. This is not easy= =20 in a world carved into 193 sovereign nations, but political boundaries ca= n=20 be penetrated far more easily than the superstitious barriers that make u= p=20 of the world's religions. The result is a planet in crisis; religion is = a=20 major part of the problem. 2. EPIDEMIOLOGY: RELATIVELY INEXPENSIVE UK STUDY SAYS IT ALL. =20 There has been no increase in brain cancers in the UK since the=20 proliferation of mobile phones in the 1990s. his firm conclusion comes=20 from a study released by the University of Manchester this week. All the= =20 researchers required were laptops to access publicly available data from=20 the UK Office of National Statistics. Contrast that with the 10 year, $1= 4=20 million case-control study of cell phone use in 13 countries carried out = by=20 the World Health Organization. The costly study seemed unable to draw a= ny=20 firm conclusions, http://bobpark.physics.umd.edu/WN10/wn052110.html . A= n=20 important branch of medicine, epidemiology is concerned with the=20 distribution of disease, but in the case of electromagnetic radiation (EM= F)=20 it got off to a bad start. In 1976 an unemployed epidemiologist, armed=20 with a list of addresses of childhood leukemia victims, drove around Denv= er=20 looking for common environmental factors. She saw a lot of power lines. = =20 Environmentalists saw brain cancer. Tort lawyers saw class-action=20 lawsuits. Epidemiologists saw full employment. But cell-phone radiation= =20 just doesn't cause cancer. Do cell phones have any observable effect on=20 our brain? Let's see. 3. MICROWAVING THE BRAIN: IS THERE AN OBSERVABLE EFFECT? Cell phones went from zero to ubiquity in a single decade. The Journal of= =20 the American Medical Association this week reported an NIH study of 47=20 healthy recruits injected with a glucose solution and then exposed for 50= =20 min to radiation from a hand-held mobile phone. The side of the head the= =20 phone was held against was switched randomly. Positron Emission Tomograp= hy=20 (PET) scans exhibited changes associated with glucose metabolism on the=20 side of the brain closest to the cell phone. This was said to demonstrat= e=20 that exposure to cell phone radiation activates the brain, but "the=20 clinical significance of this finding is unknown." Hmm, that's sort of=20 limp. I am hopeful that someone will explain to me how the effects of=20 metabolism are distinguished from changes in blood flow associated with=20 thermoregulation. The only effect of microwave photons is to excite=20 molecular vibrations (heat). Blood serves as a coolant to keep the=20 temperature of the brain nearly constant in spite of cell phone radiation.
