Submission + - Cell Phones May Affect Brain Metabolism (sciencenews.org)

commodore6502 writes: Science News Magazine and the American Medical Association reports on the results of a recent study. 47 participants had pairs of Samsung cell phones strapped to their heads, one on each side. The phone on the left ear was turned off, while the one on the right received a 50-minute recorded message. This phone was kept muted so that the subject didn’t know which phone was on, and also to prevent stimulation of the brain’s hearing center.

A few minutes after the call, a PET scan revealed that brain regions next to the working phone had higher levels of glucose metabolism. “The human brain is sensitive to the electromagnetic radiation that is emitted from cell phones,” says study coauthor Nora Volkow of the National Institute on Drug Abuse in Bethesda, MD. The increase in brain metabolism observed in the experiment may be an underestimate, because cell phones emit more radiation when a person is talking.

Submission + - 24-bit: the new way to make you pay more for music (pcpro.co.uk) 3

Barence writes: "Apple and music labels are reportedly in discussions to raise the audio quality of of the songs they sell to 24-bit. The move could see digital downloads that surpass CD quality, which is recorded at 16 bits at a sample rate of 44.1kHz. It would also provide Apple and the music labels with an opportunity to "upgrade" people's music collections, raising extra revenue in the process. The big question is whether anyone would even notice the difference between 16-bit and 24-bit files on a portable player, especially with the low-quality earbuds supplied by Apple and other manufacturers. Labels such as Linn Records already sell "studio master" versions of albums in 24-bit FLAC format, but these are targeted at high-end audio buffs with equipment of a high enough calibre to accentuate the improvement in quality."
