Man cured of HIV. Accidentally.

That's nontrivial, right? I think that's nontrivial.

Apparently it started gaining prominence amongst whitey during the time of the black death?

Tenative proof for multiple universes?

Aww hell yeah, I hope this pans out. Even though it almost certainly means nothing for humanity on a practical scale.

Holy shit, if this is actually real, it'll be a HELL of a game-changer.

So if you've been watching anything about the Japanese earthquake, you've probably been hearing about the nuclear reactors that are melting down. It is a bad thing, but these things are under control. The reactors are made to contain any melted core material. The reactors are all fucked, but no one around it is going to start glowing.

On the other hand, the fossil fuel refineries that have all been burning has been throwing off enough shit that people are being advised that when it eventually rains that they should take precautions as to not make skin contact with any of it.

This is extremely preliminary, but still, that's some pretty okay news.

Excellent article on the revisiting of the idea that refined sugar (in all forms) is not just deleterious when overconsumed, but is in fact toxic.

TA · « **Reply #394 on:** April 15, 2011, 09:12:39 AM »

There actually is a measurable, definite difference between how the body processes sucrose and how the body processes HFCS, though. So when he starts denying that to be true, I'm disinclined to believe his claims that all sugar everywhere is poison.

Cait · « **Reply #395 on:** April 15, 2011, 12:50:19 PM »

Out of curiosity, can you source that statement? A cursory look through Google Scholar suggests that HFCS and sucrose digest effectively the same, but I'd be interested to read about said difference.

TA · « **Reply #396 on:** April 15, 2011, 01:15:08 PM »

Not with enough specificity that I'd be comfortable citing it - it's something I learned long enough ago that really my sourcing would be the same googling you'd do, and I'm certainly not enough of a chemist to speak technically about it - but basically, as I understand it, Sucrose breaks down into Glucose and Fructose, which are then processed together by the same mechanism. Since Sucrose is 50% Glucose and 50% Fructose, this works in balance so the whole thing gets processed. HFCS, on the other hand, is 55% Fructose and 45% Glucose, and this means there's not enough Glucose to process all the Fructose. So 10% of it just sits there unprocessed, and since the whole glucose/fructose thing is how ATP gets recharged, it fucks up your metabolism.

Cait · « **Reply #397 on:** April 15, 2011, 06:49:47 PM »

The contention of the linked article is that fructose and glucose are not processed by the same mechanism and in fact get treated by the body entirely differently, with fructose in general being a Bad Thing. Sucrose and HFCS are thus lumped together because both introduce fructose into the body with the claimed deleterious effect.

Brentai · « **Reply #398 on:** April 15, 2011, 08:12:05 PM »

How broadly are we defining "toxic" here? Because you don't even need to get that technical to argue that processed sugar is harmful. It provides little useful nutrition while shocking the nervous system, promoting obesity, and feeding deleterious (plaque) bacteria, so yeah, it's already toxic without even getting to the bits where it may or may not fuck up your digestion system/cause diabetes/throw off aerobic energy production.
