I'm not an Alzheimer's scientist and I haven't studied it at all. What I can tell you is that the intensity of infrared light that would penetrate the skin, the skull, and finally reach the brain would be so low that it could be considered negligible. Transmittance decreases exponentially in the presence of water and I doubt any significant amount of radiation would even penetrate the person's scalp.
NewYorkCountryLawyer writes: "Ohio University, in Athens, Ohio, has found the key to getting the RIAA to stop inundating it and its students with "settlement" letters. According to the university's student online publication, the university paid $60,000, plus $16,000 per year "maintenance", to Audible Magic, the business partner of the RIAA's all-purpose expert witness Dr. Doug Jacobson, for its "CopySense" filtering software. Once it made the payments, the letters stopped. This of course raises a lot of questions as to the 'disinterestedness' of Dr. Jacobson, whose deposition in the UMG v. Lindor case was the subject of interesting Slashdot commentary."
Class Act Dynamo writes: "The United States Supreme Court today refused to hear the appeal of a high school teacher who was sentenced to over 200 years in prison for possessing thousands of child pornography images in Arizona. The justices declined without comment to hear the case. His attorneys argued that the sentence (10 years per image for the 20 images presumably leading to indictment) was disproportionate to the crime. I put this under Your Rights Online even though those rights really don't include possessing child pornography. However, what do Slashdotters think? Was the punishment appropriate for the crime? Think of the children!..but not in the way that this teacher apparently was."
