... Velcro-like junctions between the vacuole and the nuclear membranes. Nucleus-vacuole junctions were first described in 2000 by the Rochester group and remain the best-understood, inter-organellar junction apparatus in nature.

...ater was available back then, as it was needed for nuclear reactors," he said. "Investigators discovered that if you fed cells heavy water, they would operate on a 27-hour day. It was a clue that the clock had a biochemical basis, but heavy water's effect was almost forgotten as other explanations for the cl...Expressing strong concern at human cloning reports, AAAS cautions against overreaction

There is no simple solution to biosecurity, but we must construct a system of checks and balances needed to assure that the growing power of the life sciences is used to protect life, not to destroy it," said Dr. Kwik....Science's top ten: Discovery of genes' 'control switches' named top advance of 2002
