...these machines to test it in two villages, 75 kilometers apart, last year in Bangladesh. And I thought, "Wow, it's going to run on cow dung, there will be all sorts of issues. We'll send engineers, and if we can get any data..." Any data? Those machines ran flawlessly around the clock. Each village went from never seeing electricity, never having a light bulb at night, to being fully electrified. They're small villages. But they were fully electrified for nearly half year each. And the only fuel - there's no infrastructure for that either - that went into...
...study published online by the Proceedings of the National Academy of Sciences, Dr. Daniel Alkon and his group describe a simple test for the disease using easily detected proteins found in skin cells. They claim that their test can provide enough information to detect the disease at its earliest stages, when treatments might be most effective. Even more encouraging, they report that the test is sensitive enough to distinguish Alzheimer's from other dementias, including Parkinson's disease...
...while it's not quite ready for the doctor's office yet, it's still worth watching in coming years. This test, which could also lead the way to new drug treatments for Alzheimer's, incorporates some of the latest theories about how the disease gets started, and the best ways to treat it. Recent studies suggest that while it is a brain disorder, Alzheimer's earliest sign might be an imbalance in the body's immune system. This shows up as an inflammatory reaction that occurs not just in the brain cells, but throughout the body. The net effect...
...Alkon has used his test on 60 samples from patients with both the hereditary form of Alzheimer's, which hits patients earlier in life, and the more common, sporadic version that strikes in older age. He was also able to compare his test against autopsy confirmations, which were available for 20 of the samples. Among those, he says, the enzyme screen was 100% predictive...
...fine to propose speculative ideas," says Woit, "but if they can't be tested, they're not science." To borrow the withering dismissal coined by the great physicist Wolfgang Pauli, they don't even rise to the level of being wrong. That, says Sean Carroll of the University of Chicago, who has worked on strings, is unfortunate. "I wish string theorists would take the goal of connecting to experiment more seriously," he says. "It's true that nobody has any good idea of how to test string theory, but who's to say someone won't wake up tomorrow morning...
