  1. Re:Carbon Dating on Nuclear Decay May Vary With Earth-Sun Distance · · Score: 1

    The other huge problem with breeder reactors is that the ability to process nuclear waste also gives you the ability to concentrate nuclear by-products to whatever levels of concentration that you desire.

    Not really. All uranium reactors produce plutonium. Breeder reactors simply produce enough plutonium that separating it out would give economic payback. However commercial power reactors produce a mixture of plutonium isotopes that does not lend itself to strategic bombs, and plutonium is a hard material to make a bomb out of.

    In other words, this gives whatever corporation, country, or agency that has one of these facilities the ability to build a nuclear bomb.

    They already had it. If you can enrich the uranium fuel enough to make the reactor run in the first place, you can make a simple, cheap, utterly-reliable uranium bomb of the gun type.

  2. Re:And they say ... on Home Science Under Attack In Massachusetts · · Score: 1

    "The problem was that they came to put a FIRE OUT and found ~1500 bottles of chemicals that could've posed a major fire hazard."

    Compared to 25 kilos of sodium hypochlorite? Or leaky 2000 gallon tanks of petroleum distillates? Or badly-sealed oxygen concentrators? Lots of people have these in their homes, often in appalling combinations, but we don't see The Authorities throwing them under a bus and then bragging to the press.

  3. Re:beta amyloid on Drug Halts Decline In Alzheimer's Patients · · Score: 1

    It seems like more and more scientists are moving away from the beta amyloid plaque buildup hypthesis. While it seemed like a great lead, people who die with no symptoms of dementia or Alzheimer's Disease can still have a buildup of beta amyloid plaque as massive as the person who did die of Alzheimer's.

    Recent research found that beta amyloid dimers were toxic in a laboratory model of Alzheimer's disease. Monomers, trimers, and larger aggregates, as well as plaque cores were not toxic.
