Making and Breaking
Cellular Microtubules

Microtubules are active protein polymers critical to the structure and function of cells. For the first time, researchers have revealed at a molecular level the forms taken by transitional structures of tubulin (the protein from which microtubules are formed) during the assembly and disassembly of microtubules. Eva Nogales and Hong-Wei Wang of the Life Sciences Division report their findings in the June 16 issue of the journal Nature. Full story.

New Shuttle Schedules
Go Into Effect Monday

Berkeley Lab bus riders are reminded that, beginning on Monday, shuttle schedules will change to extend the wait time between departures from 10 minutes to 12 minutes on both the off-site Hearst Avenue and on-site routes. Also, drivers will now use their turn signals to indicate when the bus is or is not available for boarding. The changes are being made to better enable the shuttles to make their stop schedules without compromising safety, and to deal more effectively with increasing construction and routine traffic. Go here to learn more about the changes, here for the new off-site Hearst schedule, and here for the on-site schedule.

Beat the Rush; Buy
Barbecue Tickets Early

Tickets will be required to advance through the barbecue line at tomorrow's "First Day of Summer" celebration. They will be on sale at the event or in advance starting today at the cafeteria coffee bar. A hamburger or hot dog, chips, cookie, and soft drink or water will cost $4.29.

Cafeteria Parking Lot
Closed Tomorrow

The cafeteria parking lot will be barricaded all day tomorrow for the annual classic car show. The lawn, stage and lower cafeteria meeting room will also be reserved to avoid any conflicts. The buses will not be able to use the cafeteria stop.

Lab Chemist Receives
National Teaching Award

Stacy

Angelica Stacy, a scientist in the Materials Sciences Division and UC Berkeley Professor of Chemistry, was honored Tuesday by the National Science Foundation (NSF) as a Distinguished Teaching Scholar. Stacy is one of seven leaders in research and education who received the award for "having achieved not only groundbreaking results in research, but for major educational contributions at many levels, evidenced by their strong teaching and mentoring skills," according to the NSF. The awards, worth up to $300,000 over four years, were presented in an evening ceremony at the National Academy of Sciences in Washington, D.C. Full story.

Security Tip: Don't
Share Passwords

Sharing a password is not only downright dangerous from a security perspective, but against Lab policy as stated in the RPM. Password sharing is only permissible if employees have first obtained their system manager's explicit approval. Be especially wary of sharing passwords used for LETS access or for access to any Lab financial system because of the potential for unauthorized password use that leads to fraud. Password owners are responsible for the consequences of all use of their passwords, regardless of who actually uses the passwords.

Reminder on Contacts With State and Federal Officials

Employees may not act or give the appearance of acting on behalf of the Laboratory or the University when communicating with state or federal officials unless they are authorized to do so. To act or give the appearance of acting on behalf of the Laboratory or the University in such instances without authorization may be construed as a conflict of interest. The complete text of the Laboratory's lobbying policy, as well as guidance on appropriate contact with state and federal officials, may be found in Regulations and Procedures Manual §2.23(H), located here.
