...nd-stage kidney disease," Hammerman says. "But the waiting lists for kidney transplants can run as high as 100,000 individuals, and most patients die of the disease before an organ becomes available." Kidney function in pigs is similar to that in humans, and Hammerman's eventual goal is to use embryonic pig ...Study finds plant enzyme function changes with location in cell
...e desaturases normally found there. "So instead of waiting for multiple mutations to accumulate to produce a new function, one simple addition or deletion of an address signal -- a single mutation -- could change the enzyme's product instantaneously," Shanklin says.

...lieve that there are more plant hormones out there waiting to be discovered. Recent results from work on pea, petunia, and the small weed Arabidopsis have suggested the existence of one such novel plant hormone. The main role of this hormone is to regulate the degree of shoot branching. The hormone is appare...Patented process preserves transplant tissues/organs
