LBL Currents -- July 29, 1994

Summer students make their mark on LBL

By Mike Wooldridge, [email protected]

Summer is the season for new faces at LBL. Dozens of high school and college students spend their vacations at the Lab attending lectures, touring research facilities, and working on independent lab projects. This year, LBL's Center for Science and Engineering Education has arranged for 145 students to participate in educational programs at the Lab.

This summer is the second time around for Susan Mao, an undergraduate at Cornell University. Two years ago, Mao was Colorado's representative in LBL's High School Honors Program. Then, while in a NASA student program last year, she saw a presentation by researchers from Priscilla Cooper's lab in the Life Sciences Division on the effects of radiation on DNA. "I ended up writing to Dr. Cooper to say that I was interested in her research," she says. "I was able to get into her lab through the undergraduate research program."

Over the summer, Mao is comparing different methods of DNA immunoprecipitation, a technique that uses antibodies to recover DNA strands from solution. If anything, she says, she has found out that scientific research is not always smooth sailing, such as when the antibodies she ordered for her project turned out to have DNA-destroying enzymes in solution with them.

"But for the most part it's been very rewarding," she says. "Coming into the program I had thought that the lab work would involve a lot of mindless tasks, like running gels all day. But there is a lot more critical thinking involved, and I like seeing every step that goes into a research project."

Mao thinks that the hands-on experience will definitely give her a leg up in her studies at Cornell. "Coming to LBL I had never taken an advanced biology course--I felt a little lost in the lab," she says. "Now I have a much better understanding of lab techniques. That should help in school."

At NASA last summer, Mao helped prepare a plant genetics experiment that is slated to go up in the space shuttle next year. She hopes that the experience gained during her summers will pave the way to medical school.

Chetan Bettegowda, a high school graduate from North Carolina, is taking part in two programs while at LBL this summer. He is the winner of the first Explorer's Club Seaborg Field Trip, and is also participating the High School Honors Program.

Bettegowda won the chance to spend time with Glenn Seaborg, LBL's Director-at-Large, at the International Science and Engineering Fair in Birmingham, Ala., last spring. His prize-winning project investigated the lubricating ability of fullerene molecules.

While at LBL, Bettegowda is getting to talk one-on-one with Seaborg about his life's work in science, as well as meeting with other researchers on the Hill. He will also meet with Darleane Hoffman's group to learn about their work in heavy-ion radiochemistry, and with Albert Ghiorso's group to learn about the search for element 110. He also hopes to visit Alex Zettl's lab, where LBL researchers are doing their own work on fullerenes.

Through the High School Honors Program, Bettegowda is getting a taste of the cutting-edge bioscience research going on in the area. Activities in the program have included an overview the genetics research at LBL, a tour of the Emeryville biotech company Chiron, and a lecture on the brain by Marian Diamond, director of the Lawrence Hall of Science and UC Berkeley professor of integrative biology.

Bettegowda says he has been so impressed with the life sciences work that he is reconsidering what he will pursue when he starts college in the fall. "Before I came here I was pretty sure I wanted to go into chemistry," he says. "Now after learning about so much about biology--especially from Dr. Diamond--I think I might switch to bioengineering. I was never exposed to the science of the brain in high school."

Seaborg, who won his Nobel Prize in chemistry, says he's confident that Bettegowda's experience at LBL will keep him on the chemistry track.

"He still has a lot more to see while he's here," Seaborg says. "I think he'll still want to pursue chemistry." Bettegowda will enter Duke University in the fall.

U.S. narrows fuel economy gap with Europe, Japan

By Mike Wooldridge, [email protected]

Over the past two decades, Americans have significantly improved their automobile fuel economy relative to the rest of the world, substantially narrowing the miles-per-gallon gap between the United States and Europe and Japan.

The increase in fuel economy, combined with stability of gasoline prices, made the real cost for Americans to drive a mile in 1991 more than a fourth less compared to the cost at the beginning of the oil crisis.

The good news comes from a study by LBL's International Energy Studies Group led by Lee Schipper, an energy economist in the Energy and Environment Division. Results of the study appeared in the "ORNL Transportation Energy Data Book" published by Oak Ridge National

Laboratory.

The research group surveyed annual fuel use totals from 1970, before the Middle East oil crisis, through 1991, the last year international fuel totals are available.

The study reports that fuel economy for light-duty passenger vehicles (cars and light trucks) in the United States rose from an average of 13.3 miles per gallon (mpg) in 1973--the first year of the oil crisis--to 20.1 mpg in 1991, an increase of 53 percent.

Over the same period, European countries raised fuel economies only seven percent, from 23.0 mpg in 1973 to 25.0 mpg in 1991. Japan saw a gain of two percent, from 21.3 mpg in 1973 to 21.8 mpg in 1991.

The research group gives several reasons for the greater U.S. gains. While the United States, Europe and Japan all raised fuel taxes in response to the oil crisis in the 1970s, the U.S. hike was much greater in a relative sense, since fuel taxes before then had been very low, Schipper says. (U.S. fuel prices still remain far below those of Europe.)

The Corporate Average Fuel Economy (CAFE) standards implemented in the United States also applied significant pressure on auto makers to make more fuel efficient cars, he says. Europe and Japan had no comparable standards. Europeans also moderated the impact of higher fuel prices in part by switching to cars that used lower-cost diesel fuel, he says.

Combining the fuel economy data with fuel price figures, the researchers found surprising changes in the real fuel cost in the United States compared to the rest of the world. Americans paid $6.28 for fuel to drive 100 miles in 1973 but only $4.51 in 1991, a drop of 28 percent (1985 U.S. dollars were used as a standard, with costs adjusted for purchasing power).

In Japan, Britain, France and Italy, drivers paid about the same for fuel in 1991 compared to 1973. Drivers in Denmark paid 12 percent less, while Germans paid about 12 percent more, mostly the result of a fuel tax increase to fund German reunification.

Such a decrease in the real cost of fuel in the United States, Schipper says, could work to reverse the climbing trend in automobile fuel economies. "With the cost of using fuel at or below 1973 levels," he says, "there is less pressure for consumers and auto companies to be concerned about fuel economy."

Steady as it goes!

After eight months of preparatory groundwork and structural modifications, stabilizing buttresses are put into position around Building 90. All eight buttresses, weighing 10 tons each, will be in place by July 29, according to Matt Vail, construction manager of the seismic stabilization project. The buttresses will surround the building on three sides to bolster the structure in the event of an earthquake. Now a bright red color, the buttresses will be painted an earth tone to complement the color of the building. The seismic stabilization project is scheduled to be completed in December, Vail says.

Accelerator beam lecture for nontechnical staff

The Center for Beam Physics "Beams and U" Presents a lecture for non-technical staff by Dr. Andrew Sessler. Sessler will give an informal discussion on accelerators and beams at noon, Friday, Aug. 5 in the Building 71 Conference Room.

NEW USE FOR X-RAYS:

IBM, AT&T Corp., Motorola Inc., and Loral Corp. are discussing a joint research project on the use of x-rays to manufacture the next generation of semiconductors. IBM operates a beamline at the Advanced Light Source, a facility where cutting edge research in x-ray lithography is being conducted by LBL's Center for X-Ray Optics. According to IBM spokeswoman Tracy O'Neill, IBM's research "clearly points to x-ray being far and ahead the best alternative" for the chips that must be produced a decade from now. O'Neill said other companies may join the research venture, which could spend as much as $100 million.

In Memoriam --

Maria Feder

Maria Feder, a former LBL Library staff member, died at her home in Kensington on July 15. She worked at the Lab from January 1963 until her retirement in May 1983.

Feder was the cataloger for the LBL Library, working at the main branch in Bldg. 50. According to her colleagues, she was forward-thinking and encouraged the Library to standardize its cataloging practices.Under her urging, the Library joined the Research Libraries Information Network (then called BALLOTS) for the purpose of obtaining cataloging from that utility. The Library is still using RLIN. It is because of its early use that the Library had a fairly large portion of its cataloging in machine-readable format. This made it possible to load the records into the local on-line library catalog.

Feder is survived by a daughter, Ann Lee, and a grandson.

Delvin Embree

Delvin "Del" Embree died on July 16 at the age of 68.

Embree began his career at LBL as a member of the Electronics Installation crew in April 1952, and was immediately put to work building the Bevatron. He later became an electronics coordinator and after a number of small projects around the Lab, went to work for Spencer Knoll at the HILAC. He was instrumental in the big overhaul during the mid-1960s that changed the HILAC to the Super HILAC. Embree retired from LBL as the Electronics Coordination supervisor at the Super HILAC in October 1987.

Embree is survived by his wife Josephine of Oakland, sons Robert and Kenneth of Spokane, Wash., and brother Glenn Embree of Rigby, Idaho. Donations can be made in Embree's name to the American Heart Association.

Host of opportunities available for students

The Center for Science and Engineering Education organizes the following summer programs each year for high school and college students:

High School Honors Program

A two-week program that brings top U.S. and foreign science students to LBL for science lectures, field trips and hands-on lab assignments. The program focuses on the life sciences, and aims to acquaint students with the latest techniques and to teach them about the role of the national labs in scientific research. The program also includes activities that consider the social implications of modern science. The program is administered by Eileen Engel. Total students this summer: 69

Summer Student Research Program

A 10-week program that allows college students a chance to complete research projects on topics relevant to their fields of study with LBL scientists. Students also have the opportunity to take tours, participate in seminars, and attend classes. The program ends with a poster session at which participants present the results of their projects. This year's poster session will by held on Wednesday, Aug. 3, from 3 to 5 p.m. in the LBL cafeteria. The program is administered by Laurel Egenberger. Total students this summer: 50.

Student Research Program

A seven-week internship program for area high school students from groups underrepresented in science. Part of CSEE's Outreach Program, the program aims to increase the number of underrepresented students in science-related fields. The program ends on August 10 with student presentations at the Bldg. 66 Auditorium. The program is administered by Marva Wilkins of CSEE. Total students this summer: 26.

Patent Department: In answer to your question...

From time to time, the attorneys and patent agents in LBL's Patent Department receive questions from individual researchers, the answers to which may be of general interest to others in the Laboratory. The following is one such example. If you have questions for the Patent Department, call X7058.

Q: What is an invention?

A: The act of inventing is basically the act of bringing an idea to fruition. It begins with conception of an idea, generally a technological advance which meets a certain need. After the idea is conceived, the invention is "reduced to practice" by making and testing the invented object or process under conditions in which it will typically be used. Or, for patent office purposes, reduction to practice can be effected by filing a patent application with the U.S. Patent and Trademark Office. This is called a "constructive" reduction to practice.

Surplus chemicals available via exchange database
