Welcome to the
first issue of Science@Berkeley Lab. In the 100
years since the young Albert Einstein published the string of
papers that turned our view of the world on its head, the sciences
— all of them, not just physics — have undergone steady
but dramatic changes, the kind Science@Berkeley Lab intends
to celebrate. |

Between a Rock and a Wet Place
Billions of years after precursors of life may have formed just
where
water meets solids, we have only a limited understanding
of what happens on the molecular level. Now a new technique
has produced detailed and surprising molecular images of the
water-solid interface, revealing intermixed regions of ice-like
and liquid-like structures.

Imaging to a Fault
Most seismic waves travel through different densities of rock
and sediment, blurring the signals needed to understand how
earthquakes are triggered. Using guided waves trapped inside
the fault itself, researchers have borrowed techniques from
medicine and computer science to make CT
scans of the San Andreas Fault at its heart.

MADmap, Beyond BOOMERANG
In 2007 the Planck satellite will record the cosmic microwave
background across the entire sky — but can supercomputers
handle the data flood? All 6,000 processors of a NERSC supercomputer
running a
program called MADmap created a map from 75 billion simulated
Planck observations, proving it can be done.
