Via SynEarthNews, from Wired:
The methods of manufacturing and compressing hydrogen gas require great amounts of energy. To overcome these challenges, scientists have been tinkering with the biological powers of everything from common yeast to mysterious bacteria living on the ocean floor. At the University of California at Berkeley, mechanical engineering professor Liwei Lin is busy developing a microbial fuel cell that runs off the digestive activity of baker's yeast. The yeast feed on glucose, a simple sugar, and digest it in a process called aerobic metabolism. "We extract electrons from the yeast cells where the aerobic metabolism process happens," Lin explains. Controlling the movement of electrons to harness a renewable source of fuel remains the target for scientists designing fuel cells, which extract power from electrochemical reactions. The advantage of Lin's mechanism is that it runs on glucose, a naturally abundant resource produced by plants.

This was absolutely deilcious. This was only my 2nd try at using the bread machine first try did not come out so good. I used agave nectar, 1/3 cup. The bread was sweet and the texture was perfect. I am making it again, this time using molasses, because agave is so expensive. I highly recommend this recipe.

he didn't believe that the emzeca and behavioral issues are due to food allergies: I disagree, which is why I'm pushing for more testing.We eliminated some things from his diet for a time and then reintroduced them, and noted the reactions. It's hard to do this, though, because I can't always be sure just what he's reacting to. So, because I know that eczema can be aggravated by wheat/gluten and dairy, I try to limit those foods as much as I can (though sometimes he gets something accidentally at church from folks not paying attention). I know he reacts strongly to artificial colors and chemical salts and sweeteners, so we do what we can to avoid processed stuff all together. I'm POSITIVE that he reacts to corn, though: last time I gave him some, he had horrible, violent tantrums, hit his head on the floor, screamed (not high-pitched keening, just tantrum-y screaming). That went on for about two days, then it was like a switch was flipped in his brain and he was back to his happy, mellow, affectionate self.So I'm 100% certain there are multiple food sensitivities, but I'm having trouble pin-pointing them all, and the first allergist wasn't much of a help, IMO.I've talked to our Dr. about getting him tested for autism mostly due to the food reactions, but also his speech was a little delayed and she didn't think it was necessary. A friend recommended I check into sensory-integration techniques to help him through tantrums, but he only gets really violent when he's had a suspect food: otherwise, it's more like he has these I'm not getting my way whiny tantrums that last less than 2 minutes. It used to be that he'd have 15-45 minute long violent screaming fits 5-6 times a day or more, depending on what we ate . . . until I started taking out potential allergens.So, I guess that's why I was wondering about the Vitamin K shot, and the possibility of injury from any chemicals contained in that shot. As I'd mentioned he is also very sensitive to chemical food additives. MSG makes us all ill headaches, diarrhea and once he was given frozen yogurt sweetened with Splenda (without my knowledge or permission). That was the only new' food he'd had for a while, and he ended up with a bumpy, flesh-colored rash that started on his trunk and spread outward over his arms/legs, hands/feet, and face over about 4 days. After the rash he peeled like crazy for a few more days. Dr said, basically, that kids get rashes sometimes. Keep him clean, give him some Benadryl, call us if he gets worse. :-/ My daughter got a sick headache from the same frozen yogurt, but no rash.So, like I said, I KNOW that we have multiple food issues. But, since he's not testing positive for allergies (so far), and doesn't have severe enough behavior issues that anyone wants to test him for any spectrum disorders, I'm sort of stuck. Because I know he's extremely sensitive to chemicals I really wonder if he was injured by that Vit K shot, but I'm not really sure where to look for more information. All the docs we've been to except our family practice GP have told me that there's nothing wrong. But you know how your mommy-senses kick in, and you just have this feeling? If he was perfectly healthy with no food allergies, why all these reactions to foods?
