of genetic material at the end of chromosomes. Prior to her work, all that was known about telomeres (from the Greek word for 'end' and 'part') was that they became shorter with each cell division and, by implication, served as a kind of biological c...
Biochemists report discovery of structure of major piece of telomerase; implications for cancer
...ell divides, telomeres, which act like the plastic tips
on the ends of shoelaces, get shorter. In the natural aging process, the telomeres eventually get so short that cells can no longer divide, and they die. While telomerase is turned off in most types of healthy cells in our bodies, it is active in the...

for today's weight-conscious humans. But, he said, we may gain fundamental insights to our origins, and thus, our behaviors, by investigating the fossil record. The results of a nine-year field study of mountain gorillas living with chimps in Uganda...

...eaction between the protein 'Adhesine FimH' on the tips
of the pili and special receptors on the wall of the urinary tract. The researchers hypothesized that they could prevent this binding by administering a substance that would have a greater affinity with Adhesine FimH than with the receptors on the ur...
