"Going for the burn" pays off for women

By Jeffery Kahn

Current guidelines on physical activity and health may underestimate the benefits of prolonged vigorous exercise in women, according to the results of a study of women runners that is part of the ongoing National Runners' Health Study.

The Life Sciences Division's Paul Williams and research assistant Davina Moussa presented their findings at the 68th Scientific Sessions of the American Heart Association, held Nov. 13-16 in Anaheim, Calif. Their study of 1,833 women examined the issue of how much exercise is beneficial. Confirming that exercise improves health, their findings challenge the notion that modest amounts of moderate exercise provide benefits nearly equivalent to those from extensive, vigorous activity.

Among women runners, vigorous exercise paid off in a range of significant health benefits. A more heart-healthy cholesterol profile was obtained. Weight was significantly reduced, particularly around the waist and hips. And modest improvements were observed in blood pressure. The study found that the more miles a woman runs, the greater these benefits. That was true up to 40 miles per week.

Williams and Moussa report that the benefits of running 40 miles per week compared to running less than 10 miles can be dramatic. Women in the 40-mile club reduced their risk of dying from cardiovascular disease by an estimated 45 percent. Overall, their risk of developing heart disease is an estimated 29 percent less.

The estimates are based upon the effects of vigorous exercise on cholesterol. To carry cholesterol and fat in the blood, the body wraps them in protein packages called lipoproteins. The family of lipoproteins consists of low density lipoproteins (LDLs) and high density lipoproteins (HDLs). LDLs contain the greatest amount of cholesterol and may be responsible for its deposition in the artery walls. HDLs contain greater amounts of proteins and small quantities of cholesterol. Said to be the "good" cholesterol, HDLs are thought to remove cholesterol from the artery walls, carrying it to the liver for reprocessing or removal from the body. Research has shown that people with higher levels of HDL have less heart disease.

The Berkeley Lab study found that HDL levels increased with number of miles run, up to at least 40 miles per week. They found a 10-milligrams/deciliter difference in HDL levels between those who run 40 miles per week and those who run less than 10 miles per week.

"We found that the increase in HDL per mile run was the same for women as that previously reported in men," Williams said. "This is despite the fact that women start out with substantially higher HDL levels than men."

Weight loss from running translated into smaller waists and hips. The 10-mile group had an average waist size of 28.3 inches and hips of 37.3 inches. Average waist size in the 40-mile club was 25.8 inches with hips of 34.8 inches.

The women participating in this study were selected from the pool of 13,000 women involved in the National Runners' Health Study. Williams is the principal investigator for the study, which also involves 42,000 men.

The study of women runners was limited to those who are nonsmokers, who are not taking medications, and who are not vegetarians. Before comparing the distance run by the women to their cholesterol, blood pressure, and body masses, Williams and Moussa adjusted for a number of factors. These include age, education, and dietary intake (in terms of alcohol, red meat, fish and fruit).

The researchers also examined whether distance running conferred similar benefits on pre- and post-menopausal women and on women who are taking post-menopausal estrogen.

"The benefits apply to both pre- and post-menopausal women," Moussa said. "Women who take estrogen also benefit. Vigorous exercise appears to beneficially effect cholesterol metabolism."

The findings of this study bring into question the exercise guidelines recommended by the U.S. Center for Disease Control and Prevention and the American College of Sports Medicine. These guidelines advocate moderate exercise, such as a brisk two-mile walk every day. Furthermore, current guidelines suggest that there is little additional benefit to be gained from doing anything more.

"This study suggest to us that there are substantial health benefits to more vigorous exercise above and beyond the current recommended guidelines." Williams says. "With exercise, the greater the investment, the greater the rewards."

Engineering innovation should make new Genome Lab quake-resistant

By Mike Wooldridge

The Lab's newest building-to-be, the Human Genome Laboratory in Strawberry Canyon, should be prepared for any movement the Hayward fault dishes out, thanks to a new quake-resistant feature developed by Berkeley Lab's structural engineers.

Builders will reinforce the joints of the Genome building's skeleton with special cover plates. The flange-shaped, steel plates spread a quake's pressure out from the joint into the lengths of the beams, like a protective splint.

According to Lab structural engineer Fred Angliss, the new design is dollar-for-dollar the most effective way engineers have found to reinforce "moment-frame" buildings, which were some of the hardest hit structures in the Northridge earthquake.

Angliss and fellow engineer Bob Shilling, working with the firm of Forell/Elsesser Engineers, Inc., developed the new design. It will be used for the first time at the Genome Laboratory, which is scheduled for completion in 1997. The nearby Hayward Fault runs under UC Berkeley's Memorial Stadium and along the southeast flank of the Laboratory.

A full-scale mock-up of the joint design was tested recently at UC Berkeley. Girder joints held steady through simulated quake forces far beyond those where standard designs have snapped.

"It is an exciting piece of research for structural engineering, which is usually a pretty quiet field," said Angliss. "Usually it only gets exciting when there are earthquakes."

Cover-plated joints are a much-needed improvement for the Genome Lab and similar buildings, which have "moment-frame" architectures. In moment-frame buildings, an earthquake's pressure is brought to bear at the joints where the girders connect to the building's columns. This is in contrast to other building designs, where pressures are absorbed by thick walls or bracing in the spaces between girders.

"Architects and owners like moment-frame designs because it gives them wide-open interiors," Angliss said. "There are fewer restrictions on how you arrange furniture, more freedom to walk around, more space for windows. It's a very owner-friendly design." Planners chose a moment-frame design for the Human Genome Lab in 1993.

In 1994, however, moment-frame buildings took a major hit during the 6.7-magnitude Northridge earthquake. Engineers found snapped bolts, broken welds, and cracked girders and columns in more than 100 moment-frame structures near the quake's epicenter.

"While the buildings didn't collapse, they were in no shape to withstand another earthquake," he said. Building codes were revised in the quake's aftermath. Today, the joints of a proposed moment-frame building must be rigorously tested under major-quake conditions before the structure can go up.

The Genome Lab's design passed its test recently at UC Berkeley's Davis Hall. Thirteen-foot-long girders were welded into a "T," just as they will be connected at the Genome Lab. The special plates were welded to the top and bottom of the joint.

The "T" was mounted parallel to the ground with the extending beam attached to a powerful ram. The ram simulated an earthquake's lateral thrusts by wrenching the end of the beam from side to side.

In tests of other joint designs, joints typically break when the beam is pushed slightly more than an inch to each side. The new joints lasted past five inches.

"The performance surprised everyone," Angliss said. "The technicians at certain points during the tests would cover their ears. We found out later that this was the point at which most other designs have broken. They make a heck of a noise when they break."

The new joints will ensure that the structural columns of Genome Lab are the strongest part of the building's skeleton. This is critical since when a column fails, a building will often collapse. In contrast, failure of a cross beam will usually result in only a badly sagging floor.

Other methods for improving moment-frame joints have involved complicated welds that are too expensive for widespread use. Angliss expects it will be easy for engineers to apply the plate-based design to other new moment-frame buildings.

CAPTION: The new Genome Lab's girders passed quake tests with flying colors. Berkeley Lab structural engineers helped develop the special design.

1995 United Way campaign begins

The Laboratory's 1995 United Way campaign kicks off next week with the distribution of information packets to each employee. The packets describe the donation options and some of the programs that benefit from United Way funds.

The United Way of Alameda and Contra Costa counties has instituted some changes since last year which emphasize "priority outcomes." Goals have been set that focus on agencies achieving positive results for local communities. These goals are listed in the information packets, and can help you decide how you would like to have your donation distributed.

If you do not receive an information packet, or have questions regarding this year's campaign, contact campaign coordinator Shaun Fennessey at X5122.

LAB PEOPLE:

Sylvia Spengler of the Life Sciences Division was elected co-director of the Program for Mathematics and Molecular Biology (PMMB) at the Fourth Annual meeting in Santa Fe, N.M. on Nov. 13. PMMB is sponsored by the National Science Foundation and has members at nine universities thoughout the country. De Witt Sumner of Florida State University shares the four-year appointment.

VIRTUAL FROG STILL A HIT:

PC Computing magazine has selected the Virtual Frog-Dissection Kit, an interactive educational experience developed at Berkeley Lab, as one of the best sites on the World Wide Web. In the December 1995 cover article, the magazine prints its list of "1001 Best Web Sites." The Frog Kit not only made the big list, but was singled out as one of the magazine's 10 favorite sites. The Frog Kit, which can be viewed on the Web at http://www-itg.lbl.gov/vfrog, was developed by ICSD's David Robertson and Bill Johnston to demonstrate the possibilities of the Web for interactive scientific visualization and for education. A person using the Frog Kit, which is a component of the Whole Frog Project, can select and view images and information about various parts of a frog's anatomy. Using the interactive part of the kit, the user controls the view angle and selects which organs and features are visible or invisible. Users can also view "movie" clips of rotating 3D features of the frog. In the past year and a half, the Frog Project has been accessed more than 2.4 million times by users in 75 countries.

STUDMUFFINS OF SCIENCE:

In the beginning, it was a joke. As the joke spread, it became an idea that was too good to pass up. The result is the new Studmuffins of Science calendar, featuring "buff, bronze bioengineers" and more. Studmuffins was created by Karen Hopkins, a biochemist-turned-science-writer who is assistant producer of "Science Friday," a National Public Radio program about science that airs Fridays. Looking for candidates for her calendar, Valentine put up an ad that read ``If you have a Y chromosome and a Ph.D., you can be Dr. December." This year's dozen range from computer scientist and astrophysicist to professors who hope their pin-up pose won't affect chances for tenure. The calendar is being sold at the Lawrence Hall of Science as well as Barnes & Noble and the Borders book chains. You can get a sneak preview on the Web at http://studmuffins.clever.net.

DOE ABOLISHES OFFICE OF R&D MANAGEMENT:

In response to Congressional direction, DOE has formally abolished its Office of R&D Management, which, under the direction of Alexander MacLachlan, oversaw the Department's technology transfer programs. The FY96 energy and water appropriations bill signed into law by President Clinton this month (see Currents, 11/17) slashed funding for CRADAs at the non-defense national labs to just $18 million, less $1.5 million that was earmarked by Congress for severance pay. The Administration had requested $58.8 million for this program, which is also known as the Energy Research Laboratory Technology Transfer (ERLTT) program. DOE is now prioritizing its existing CRADAs. According to MacLachlan, those that rank in the top two-thirds are likely to survive "relatively unscathed," while those that fall in the bottom third are likely to be "stretched out or have their scope of work modified."

EXPERIMENTS AT CEBAF UNDERWAY:

The first experiments at the Continuous Electron Beam Accelerator Facility are underway. CEBAF's beam is being directed onto three targets made of carbon, iron and gold to measure the motion of protons through nuclear matter. CEBAF is under the direction of former Berkeley Lab Deputy Director Hermann Grunder.

SERS program nears semester's end

By Brennan Kreller

Fourteen undergraduates who have worked with Lab researchers will soon complete their assignments for this fall's Science and Engineering Research Semester (SERS). The DOE-funded program has allowed these students from around the country an opportunity to become actively involved in ongoing laboratory research using the state-of-the-art facilities provided by the Laboratory.

SERS was established by DOE to help encourage undergraduates to pursue advanced degrees in science and engineering. A term away from campus is rather unusual for science majors, but is comparable to a research semester abroad for a liberal arts student. Students work alongside mentor scientists, gaining experience in a nurturing work environment with researchers who share their excitement about learning and discovery.

Participants also attend regular lunch-time seminars throughout the semester, featuring scientific presentations as well as talks on such topics as tech transfer, graduate school preparation, and presentation skills.

The culminating activity for the students is the final presentation, during which the students give talks on their respective research experiences. The presentations will take place in the Bldg. 66 Auditorium on Dec. 12 and 13. Look for the schedule in next week's Currents.

CAPTION: SERS students finishing up their research semester at LBL are (front row, l-r) Janel Baptista, Amber Climer, Leanne Ma, Stella Sarraf, Makeba Fussell, Chris Ganson, Robert Seaborn, Martin Shim, and (back row, l-r) Shea Jones, Evan Scannapieco, Jonathan Rheaume, Geraldine Aragon, and Alan Cheng (not pictured: Carmen Ortiz-Aponte).

NATIVE AMERICAN HERITAGE MONTH


Navajo "code talkers" helped win the War

By Brennan Kreller

Three Navajo veterans of World War II, Jim Begay, Keith Little, and Albert Smith, came to UC Berkeley's Dwinelle Hall last month to share stories of a simple life that changed suddenly when they were recruited by the U.S. Marine Corps. They told their story as part of a celebration of Native American Heritage Month.

For 50 years America's "secret weapon" in the defeat of Japan was thought to be the atomic bomb, but the real secret weapon may have been a virtually impenetrable code--based on the Navajo language--that made it impossible for the Japanese to follow American military maneuvers.

More than 400 Navajo were recruited by the Marine Corps between 1942 and 1945 as communications specialists. Rather than devising a code language based on English, in which many Japanese officers and language specialists were fluent, the Marines had the Navajos devise a code based on their own language.

The rationale for using Navajo was that it was a rich language from which many code words for military terms could be devised. It was not a written language and could only be spoken by the Navajo and very few others who had lived among them.

Military communications were written in English and then translated orally into Navajo over the radio by a code talker. Another code talker would receive the message and translate it back into English.

Code talkers were involved in all of the major battles of the Pacific, including Guadalcanal, Okinawa, and Iwo Jima, and are considered to have been integral to the American victory.

Ironically, Navajo at the time were segregated from whites and not allowed to speak their own language in American schools. Although they could not vote, they were asked to enlist in the Marines.

Their role in the American victory gave them a certain amount of respect in society. However, they were forbidden by the military to talk about their work. When the code talkers returned to the reservation, they could not even talk about any battles or military events. Navajo society did not welcome stories about violence, fearing that such talk could "infect" their culture.

Eventually, the code talkers were recognized for their achievements. Although they received certificates of achievement from the President in 1951, their work was not known for several decades. In 1982 President Reagan designated August 14 as National Code Talkers Day, and an exhibit honoring the code talkers was recently unveiled at the Pentagon. The code talker presentation was co-sponsored by Berkeley Lab and UC Berkeley.

CAPTION: Navajo code talker Albert Smith joined the Marines age 15, claiming to be 17, so he could work alongside his brother. He overcame a stutter to become a successful code talker.

Call for postdoc fellows

The call has been issued for DOE's 1996 Alexander Hollaender Distinguished Postdoctoral Fellowship Program. The fellowships provide a $37,500 first-year, and a $40,500 second-year stipend aimed at supporting the mission of the Office of Health and Environmental Research. OHER's research mission includes the study of atmospheric, marine, and terrestrial systems; molecular and subcellular mechanisms underlying human somatic genetic processes; nuclear medicine; structural biology; and development of instrumentation necessary to achieve programmatic success.

The fellowship program was established in 1986 in memory of the late Alexander Hollaender, the 1983 recipient of DOE's Enrico Fermi Award. Research conducted under his direction was instrumental in making DOE's biomedical research programs among the most prominent in the world.

Completed applications and supporting materials must be received by the Oak Ridge Institute for Science and Education before Jan. 15, 1996. Fellowship offers will be made in May 1996, with expected start dates between May 1 and Sept. 30, 1996.

For more information, application materials, or a report summarizing Berkeley Lab's OHER research, contact Rebecca Rishell at X6689.

Revelers usher in winter solstice

By Mike Wooldridge

Holidays are a time of transformation for some. Ken Woolfe, an electronics coordinator at the Advanced Light Source, will be putting on medieval garb and taking the stage.

Woolfe is performing in this season's San Francisco Bay Revels. The holiday event, derived from pre-christian European celebrations of the winter solstice, features a lively mix of mummers' plays, street songs, sword dances and general merry-making, with an emphasis on audience participation.

With its winter traditions and colorful costumes, Revels involves many rituals now associated with the modern celebration of Christmas, such as the hanging of mistletoe and the wearing of red and green.

Now in its tenth year, the production brings together a diverse mix of talent as well, with seasoned professionals sharing the stage with amateurs. Woolfe, for instance, has never sung in front of a large crowd. "I've had some singing experience with an amateur group in Oakland, but never anything like this," he says.

Woolfe says his wife saw the call for players in Revels and urged him to give it a shot. "I've always been a bit timid about performing in front of a crowd," he says, "but I decided to give it a try."

Woolfe and 100 other singers and musicians will share the Revels stage with comic Geoff Hoyle, of Cirque de Soleil and Pickle Family Circus fame.

Hoyle will play The Fool, a character who presides over the banquet hall of a medieval castle full of solstice celebrants. Other characters include a giant dragon six-children long, musicians playing instruments of the period, and a chorus of young carolers.

For his role in the adult chorus, Woolfe will play a leathersmith named Kenneth Strapper.

How has it been as a Revels rookie? "It was intimidating at first, but the veterans help you feel comfortable," Woolfe says. "Geoff Hoyle and the other pros keep the rehearsals pretty lively."

The Revelers have begun nightly rehearsals in preparation for four performances Thursday, Dec. 7, through Sunday, Dec. 10. Revels is performed at the Scottish Rite Theater, 1547 Lakeside Dr., Oakland. For ticket information, call the Revels box office at 452-8928. Woolfe has also posted information in the cafeteria.

Lab a leader in international energy efficiency analysis

Contributed by Steven Pickle

The U.S. Department of Energy is the world leader in the analysis of effective energy efficiency performance standards, and the majority of this analysis is conducted at Berkeley Lab by the Energy Analysis Program's Energy Conservation Policy Group (ECP). In early October, three ECP analysts went to Russia, where they conducted workshops on the process of establishing efficiency standards. Later in the month, ECP was visited by a team of energy efficiency engineers from Mexico and Colombia.

The Russian visit was conducted at the invitation of the Russian Ministry of Fuel and Energy, the Russian State Research Institute of Certification, and the Center for Energy Efficiency. In a week of meetings in Moscow, ECP's Tony DeVuono, Irina Shukman and Sajid Hakim discussed the process of analyzing and selecting appliance efficiency performance standards.

Russian representatives were eager to learn from American experience because Russia is about to enact its own version of the 1987 National Appliance Energy Conservation Act (NAECA), which established federal appliance standards in the U.S. "They have a draft law likely to go into effect next year, the goal of which is to introduce standards in order to raise the quality of their own consumer products," DeVuono said. He said the Russians are looking to target fluorescent lamps and ballasts, small motors, refrigerators, and residential boilers.

The group visiting ECP from Mexico and Colombia was comprised of five members of the Mexican Instituto de Investi-gaciones Eléctricas, and one member of Colombia's Instituto de Ciencias Nucleares y Energías. The Mexican researchers are actively involved in developing energy efficiency standards for Mexico and in helping to assess the prospects for similar standards across Latin America.

Having closely studied recent DOE Technical Support Documents produced by ECP on appliance efficiency standards, the visiting researchers came to Berkeley Lab to learn more about ECP's economic and energy modeling systems, and about ECP's detailed appliance and lighting engineering assessments. According to ECP leader Jim McMahon, "Technological improvements that have occurred in the U.S. set an example from which Mexicans, Colombians, and others can benefit."
