While soaring oil prices in the 1970s prompted major advances in the nation's energy efficiency, this year's surge in fuel costs has not sparked a new wave of conservation. Experts say they expected petroleum demand growth to slow in 2004. Instead, worldwide oil demand grew more than 3 percent. Some now say that conservation is unlikely to play a bigger role in the United States, unless predictions that the era of cheap oil is over come true. Mark Levine, director of Berkeley Lab's Environmental Energy Technologies Division said he was "disappointed" though not entirely surprised by the inelasticity of oil demand over such a short period of time.

Just
five years ago, Rett Syndrome was tracked to mutations
in a gene on the X chromosome, MECP2. But how this gene,
not previously associated with the brain or nervous
system, could cause a neurological developmental disorder
remained a puzzle. Now, a team of scientists with Berkeley
Lab, supervised by biochemist Terumi Kohwi-Shigematsu,
has developed new methods and overturned mistaken assumptions
to discover how the product of this gene, the protein
MeCP2, can remodel chromatin, the material that makes
up chromosomes. Full
story.
