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. Full story.

Ergonomics Fair
Aug. 20-21

Check out the latest ergonomic products and solutions for offices, labs, and shops at the ninth-annual ergonomics fair, from 11:30 a.m. to 2 p.m., Wednesday, Aug. 20 and Thursday, Aug. 21 at the Cafeteria patio area. Vendors will be there with hands-on displays, as well as furniture, keyboards, accessories, and tools. Information about ergonomics can be found at the Environment, Health, and Safety Division website.


Girl Scouts Attend
Science Camp

Image of a Girl Scout

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.
