Tiny
Sensors Help Track
Health of Redwoods California
forest ecologists are rigging redwood trees with
networks of wireless sensors, using some of the
tiniest such devices ever made to track the health
of Earth's biggest living things. The project
is a collaboration led by UC biologist Todd Dawson
and Berkeley Lab computer scientist David Culler.
Fifty "micromote" sensors, each packed
with its own battery and transmitter within a
weatherproof container the size of a pill bottle,
now dangle like earrings from the branches of
three trees growing in the UC Berkeley Botanical
Garden's Mather Redwood Grove. The sensors continuously
monitor light, moisture and temperature at varying
heights. The project has turned the stately grove
in Strawberry Canyon into a proving ground for
a technology that experts say could revolutionize
forest science. Full
story. |

Repairing Energy Network
Could be Difficult and Expensive
The
nation's worst blackout is putting energy —
especially upgrading high-voltage transmission lines
— back on Congress' radar. But resolving the
problem could be difficult and expensive. The grid
needs mandatory reliability standards, Energy Secretary
Spencer Abraham said Sunday as he made the rounds
of the television talk shows. Regional conflicts,
the controversy of electrical industry deregulation,
and concern about a power struggle between state
regulators and those in Washington are among the
issues that could sidetrack whatever might be needed
to insulate the power system from future blackouts.

| Girl
Scouts Attend
Science Camp
No,
they’re not here to sell cookies. Some 30 Girl
Scouts from troops in Oakland and Richmond are attending
the lab’s Science Exploration Camp to learn more
about energy, computers, chemistry, and more. This week
marks their third and final week on the hill. In addition
to classroom learning activities — such as energy
scavenger hunts, brain teasers, math puzzles, and making
liquid nitrogen ice cream — the campers have also
made field trips to the Exploratorium in San Francisco,
Strawberry Canyon Pool, and sports at Ohlone Park in
Berkeley. The cost for their visit was fully funded
by the Elizabeth and Stephen Bechtel, Jr. Foundation.
This marks the first time the Science
Exploration Camp has hosted the Girl Scouts.
