Comment Re:low carb and low PUFA vs high Omega-3? (Score 1) 166

Low carbohydrate diets may have benefits for the brain as well. They are now recognized as a powerful tool for treating epilepsy and there are reports that in cases it can actually cure the disorder. Some people with bipolar II have found that low carbohydrate diets can be more effective than drugs for managing the disorder. There is also evidence that low-carbohydrate diets can be used to treat Alzheimer's.

The disturbing implication here is that if switching from a high-carbohydrate Western diet can fix brain disorders, then maybe the Western diet and in particular low-fat diets are causing a lot of these problems in the first place. Certainly there's not much evidence that cutting fat out of diets has made us any healthier.

Submission + - The Government Can No Longer Track Your Cell Phone Without a Warrant 1

Jason Koebler writes: The government cannot use cell phone location data as evidence in a criminal proceeding without first obtaining a warrant, an appeals court ruled today, in one of the most important privacy decisions in recent memory.
"In short, we hold that cell site location information is within the subscriber’s reasonable expectation of privacy," the United States Court of Appeals for the Eleventh Circuit ruled. "The obtaining of that data without a warrant is a Fourth Amendment violation."

Note that the study included an experimental manipulation of anesthetic exposure in a sample of rats. This was an experimental manipulation which means that the author's could make a much stronger claim for causation. As far as mechanisms, this is being explored but it appears to be something that normal processes of synaptogenesis and synaptic pruning.

Submission + - Computer Chronicles Now Streaming 24x7 on Justin.tv

An anonymous reader writes: Some of us might remember the television series Computer Chronicles, created by Stewart Cheifet. It aired on Public Broadcasting Service (PBS) during the mid 80's to early 2000's and documented the rise of the personal computer from its infancy to the immense market at the turn of the 21st century. Last week, the unofficial YouTube channel ComputerChroniclesYT announced they were streaming past episodes 24x7 live on Justin.tv.

Comment Re:Turing Test Failed (Score 1) 432

What has been conducted precisely matches Turing's proposed imitation game.

The question is, how informative is an imitation game? If we've shifted the goalposts I think it's because these ones just aren't very informative. The implicit argument of the Turing Test is that a sufficient good imitation of intelligence, indistinguishable from the real thing, must at some level be intelligent. Basically, fake it until you make it. Like in Blade Runner- the replicants remember, love, fear, hate; they do everything humans do in a way indistinguishable from us, so they must at some level be human. Pretend long enough and hard enough and eventually it becomes the real thing. It's a plausible argument on the surface, but sort of blows up on closer examination.

For example, years ago there was an effort by psychologists to rehabilitate sociopaths with extensive talk therapy, teaching them to share and be more in touch with their feelings. It didn't really work, though. It taught them how to speak the language of empathy and say the right things to convince people that they were caring human beings, but underneath they were still sociopaths, given a chance they'd go off on another killing spree. Learning to act like caring human beings didn't actually make them caring beings. They were still monsters, but now they just had better camouflage. Imitating empathy didn't actually make them empathetic.

Let's choose another example- perhaps more than hypothetical in light of Turing's tragic life and the culture of his time. Let's imagine a man, a criminal deviant who likes men, but instead he pretends to be a normal man who likes women. He has women friends. He goes on dates with women. He marries a woman. They have children, and live together in a house in the suburbs. If he pretends long enough, and hard enough, for years and years, does he at some point stop becoming a criminal deviant and start becoming normal? I'd argue that the Turing Test and its emphasis on imitation might say a lot more about what was going on inside Turing's head than inside the machine.

An alternative to fasting might be ketosis. During fasting, all available sugar is consumed and the body starts producing fat bodies called ketones that are burned by the mitochondria instead of sugar. It's impossible to continue a fast indefinitely because the body eventually runs out of fuel- in other words, it starves. But if the diet is sufficiently low in carbohydrates (>60 g/day) and high in fat, the body can burn fat-derived ketones indefinitely and remains in a state of ketosis, in effect a long-term fast. Nobody understands quite how it works, but it's been shown to produce dramatic improvements in people with epilepsy (major improvements in most patients, complete remission in a handful), bipolar depression, and perhaps neurodegenerative disorders as well. At any rate, it's clear that how you eat can have profound effects on your health, and that more research needs to be done into dietary therapies.
