Finding Reveals Broader Role Of Telomerase Enzyme, Suggesting New Target For Extending Life Span Of Cell
... away, youstart to see an effect. This is why the capping
role of telomerase isn'trevealed until the chromosomes get fairly short. When the chromosomes' telomeresare still very long, they do just fine stabilizing themselves by other means." The question now, said Blackburn, is how the telomerase works in it...
Wisconsin lake study shows persistence of acid rain effects
...ts are in large part thanks to the Clean Air Act's capping
of sulfur dioxide emissions. But that good news is tempered by the evidence from Little Rock that lakes recover slowly from biological changes driven by acidity. Frost says other studies of northeast U.S. lakes have found little improvement in pH l...

process. Previously, scientists had thought that Est1 was a fixed part of the telomerase bundle and played only a minor role in its activity. "This is really a shift in the way we were thinking," said Zakian. "When we went into these experiments, ev...
