5/25/2003: Lithium might work against Alzheimer's - Nando Times
    This is based upon a study in mice. The next move here will be to study manic-depressive patients to see if they get Alzheimer's disease.
5/26/2003: Lithium Shows Promise Against Alzheimerís In Mouse Model
    This article mentions the side effects of lithium treatment, and suggests that a combination of, e. g., ibuprofen and lithium might be more effective against Alzheimer's than lithium alone.
5/25/2003: Ban on genetic discrimination by insurers, employers advances - Nando Times
    Of course, this is tied to the critical issue of whether employers can be selected on the basis of their genetic sonstitutions.
5/25/2003: Iraq was no immediate threat to US, senator says in slam at Bush - SpaceDaily
    This article by Senator Robert Byrd discusses the invasion of Ira.
5/25/2003: Pentagon defends electronic snooping program, changes name - SpaceDaily
    Now that's clever! The Total Information Awareness Program was under broad-based attack, so the Pentagon has changed its name.
5/25/2003: MICHELLE THALLER: Artificial black holes - on the threshold of new physics - Nando Times
    This is an interesting topic. Can we construct a black hole that will last month? A year? Ten years? Could we create tiny black hole in outer space?
5/26/2003: Bacteria Convert Food Processing Waste To Hydrogen - Science Daily
    Unlike "The Sludge Buster", this is probably not a sufficiently robust approach to solving our fossil fuel problem, although it will deliver both hydrogen and methane. The article says that both methane and hydrogen are converted into electricity with about 80% efficiency in a fuel cell.
5/26/2003: LED to Light the Future?  - ABC
    Right now, LED's cost about 10 times as much as an incandescent bulb, and are about twice as efficient as a halogen light bulb, compared while fluorescent lamps are nearly 5 times as efficient as incandescent lamps (which is why the world runs on fluorescent lamps). But LEDs are cool and rugged, and they last for 50,000 hours. Research is underway to cut their costs, and improve their efficiencies to match or exceed those of fluorescent lamps.
5/26/2003: Thermopower in a spin
:- PhysicsWeb
    In 1997, researchers in Japan discovered a new thermoelectric material with a cooling capacity nearly ten times larger than that of ordinary metals. Now, Phaun Ong at Princeton University and colleagues have shown that electron spin and electron-electron interactions are responsible for the high thermopower in this material. The result could help in the search for better thermoelectric materialssis
