...words "song," "guitar" and "heart" - which actually do rhyme in Portuguese, cançao, violao and coraçao, respectively. Having attended the first week of Rock in Rio, having seen an endless procession of Brazilian bands, having heard an endless series of Brazilian songs, sweated under Brazilian sunlight, eaten Brazilian food, danced (or attempted to dance) Brazilian dances, I think I've gotten some idea - not the whole concept, but a working notion at least - of the connection between cançao, violao, and coraçao and why the bond matters. At Rock in Rio there...
...those checks is the T cell's dependence on another cellular player: the antigen-presenting cell. The APC is an omnivorous creature whose job, among other things, is to gobble up microbial invaders. To initiate the immune response, the APC coughs up a molecule from the bug it has eaten, latches on to a helper T cell and "presents" it with a target molecule, instructing the T cell to prepare its troops for war. This activation is tightly controlled; it cannot occur without the lockstep interaction of several proteins on both cells--one of which is known...
...Genetically Modified Foods Millions of bushels of genetically modified corn, approved for animal feed but not for human consumption, turned up in Taco Bell taco shells and other food products. Though most of the food was recalled before it was eaten, the high-tech mix-up increased public skepticism about so-called Frankenfoods. In the meantime, public-health experts still have high hopes for golden rice, a strain that's genetically enriched with a precursor of vitamin A and that could help prevent blindness in hundreds of thousands of children in impoverished countries each year...

...this protein could cause of food allergy is miniscule; its structure differs from known allergens and there have been no reported cases of an allergic reaction. Its presence might even be healthy: farmers need to use less pesticide if the plant provides its own protection. You may have already eaten some Cry9C in your corn flakes. The 1998 and 1999 crops were mixed with non-modified corn and released into the food supply...
