...neutrino bursts could help pin down theoretical models not only about how stars die but also about how the universe might expire. A debate is raging over how much "dark matter" -- stuff invisible to astronomers -- exists in the universe. If there is sufficient dark matter, its gravity will be enough to force the universe, still expanding from the Big Bang, to slow, stop and fall together again in a "Big Crunch." If the necessary matter does not exist, the universe will expand forever...
...Cloud; the sun is thought to have only about a tenth of the mass necessary to become a Type II supernova and has no stellar companion to contribute the mass necessary to turn it into a Type I blast. But that will be of little comfort to whatever creatures exist on earth when the sun is in its death throes; the $ final solar convulsions, while feeble compared to those of a supernova, will wipe out all life on the planet...

...understands exactly how or why the Fragile X mutation affects the brain. Autopsy studies by IBR Director Henry Wisniewski and his colleagues have shown that the number of connections, or synapses, between brain cells in autistic children with Fragile X syndrome is unusually low and the connections that do exist are not well developed. "In normal adults the connections are short and stubby," says Brown. "In Fragile X, they are longer and thinner, as in newborns. It's as if a stage of development hadn't been achieved. They haven't made the normal contacts between cells...
