Hundreds of eager volunteers and a perfect fall day greeted an estimated 6,000-plus visitors to the Lab's second Open House, held on Saturday, Oct. 18. Guests at the six-hour event included townfolk, tourists, Lab employees and their families, and young people from kindergartners to graduate students. From grandparents to toddlers, visitors arrived by the busload or hiked up the hill for an intimate look at the sometimes mysterious-seeming goings-on at Berkeley Lab.
"A World of Great Science" was the event's title; visitors got great science and more. After examining the world's most powerful dipole magnet, manipulating images of tiny crystal structures on the Atomic Resolution Microscope, watching a phalanx of robotic gene sequencers move through their paces, or taking in any of numerous other tours, lectures, and exhibits, visitors could enjoy refreshments at the food tents and listened to live music. Music groups included Lab musicians who played rhythm and blues, jazz, rock and roll, and even performed Scottish dances on the lawn in front of the cafeteria.
Associate-Director-at-Large Glenn Seaborg was honored at a noontime ceremony in front of Bldg. 50 for his many contributions to science, culminating in the recent official designation of the element seaborgium, element 106. Director Charles Shank led the tribute, citing Seaborg's inspiration to generations of scientists, including himself. October 18 was proclaimed "Glenn Seaborg Day" in the City of Berkeley by Mayor Shirley Dean. Seaborg received trophies which ranged from the sublime--an up-to-date periodic table of the elements made of crystal and presented by the Lab--to the ridiculous: a "Flubber" baseball cap presented by the Walt Disney Company, which also gave children in the audience posters of the new movie starring Robin Williams. (Seaborgium is apparently crucial in making flubber.) Seaborg responded to it all with what Kira Thomsen-Cheek of the Open House task force describes as "dry wit."
Later Seaborg spent hours talking with young visitors and signing copies of the periodic table. "I saw him surrounded by 30 delighted kids who were craning their necks to look up at him," says Roberta Boucher, the director's liaison to the task force.
One young woman with a Seaborg-autographed table of elements later showed up at the 88-Inch Cyclotron and peppered its director, Claude Lyneis, with questions. "Boy, was she charged up," Lyneis says. "She'd made up her mind that she wanted to spend her life doing nuclear science."
According to Lyneis, the somewhat out-of-the-way 88-Inch Cyclotron got "as many people as we could deal with," and the centrally-located Advanced Light Source was mobbed. "It was a thrill dealing face-to-face with people," says Art Robinson, who was crammed into a cave explaining the storage ring's magnets to visitors "awed by this monster they were looking at. They were very enthusiastic, very curious about what we were doing here. It was hard to get people to leave."
Children had a field day
No one was more enthusiastic than the children: tearing delicate electronic hardware to pieces with screwdrivers at the "electronic petting zoo" inside the ALS; on the porch outside, oohing, ahhing, and giggling at the sight of bloated, dehydrated marshmallows; or shrieking with delight as they smashed broccoli stalks they had just immersed in liquid nitrogen to smithereens.
Children dragged their parents behind them all over the hill as they collected stamps on their passports from such locations as the Fire House, the Advanced Engineering Technology Labs' glass-blowing demonstration, or from volunteer college students, who popped questions like "Is an electron bigger or smaller than the tip of a pencil?" The youngsters' correct answers were rewarded with stamps and stickers.
Kids were everywhere--from the Science Discovery Theater in Bldg. 66, to the Family Science Tents behind Bldg. 70. "We had to struggle to fit them all in," says volunteer Marilyn Chartock. "We kept sending for more supplies."
That science can be as much fun for older kids and for adults was amply demonstrated in the National Energy Research Scientific Computing center's visualization lab, where molecular structures seemed to come right out of the screen over the heads of front-row observers--and were manipulated by some visitors to the verge of motion-sickness. A web-surfing exhibit, partly staffed by six volunteers from Silicon Graphics, Inc. and stocked with 20 terminals on loan from SGI, allowed visitors to morph a person's live, on-screen head into a pointy cable and tie it in a knot.
First Open House paved the way
"It really helped to have the Open House two years ago under our belt," says Roberta Boucher. "We put what we learned to use, with more and better signs, more parking and shuttle buses, and more hands-on exhibits." Starting at the central exhibit area, visitors found their way to every part of the Lab, from medical imaging exhibits to talks on the theory, application, and life-style of science, to tours of the waste management facility.
Boucher calls the Open House task force "an incredible group to work with--a dozen `outreach types' plus representatives from 20 divisions and programs and some 500 volunteers. We had no medical emergencies, no lost kids, and of the 220 questionnaires we handed out, more than 95 percent came back with tremendously positive responses."
Perhaps the best measure of the second Open House's success was the combined exhilaration and exhaustion on the faces of people making their way down the hill after a day spent looking close-up at Berkeley Lab's world of great science.

The enormous success of Berkeley Lab's second Open House was a real tribute to the hard work, enthusiasm and commitment of the hundreds of employees who volunteered their time and energy both before and during this outstanding event. Your unflinching efforts helped showcase our research facilities in the best possible light and opened the eyes of the world to the wonders of the science being conducted at our institution.
Seldom have I felt as much pride in the excellent work being done at the Lab as I did on that bright Saturday as I witnessed the joy and enthusiasm of children and adults alike as they experienced the excitement of science and discovery. Their positive experience here will eventually translate into broader public support for the Lab and for science in general.
Again, my congratulations to all of you who helped make this year's Open House such a big success.

Genetically engineered mice that fully mimic all the symptoms of human sickle cell disease have been developed by scientists here at Berkeley Lab. With this new mouse model, medical researchers finally have a means of effectively testing experimental treatments for the disease.
A team led by Dr. Chris Pászty of the Life Sciences Division has reported the creation of a new strain of mice that carries human hemoglobin genes with no counteracting mouse genes. This enables the mice to develop all clinical manifestations of the sickle cell disease.
The research has been reported in this week's issue (Oct. 31) of the magazine Science. In addition to Pászty, other members of the team from Life Sciences included Catherine Brion, Mary Stevens, Mohandas Narla, and Edward Rubin. Also contributing were Ewa Witkowska of the Children's Hospital Oakland Research Institute and Elizabeth Manci of the University of South Alabama Doctors Hospital.
Each year approximately 100,000 babies in the world, mostly of African descent, are born with sickle cell disease, a painful and debilitating condition caused by a mutant hemoglobin gene. Although sickle cell disease has been extensively studied, there is still no effective treatment--a failure attributed in part to the lack of an animal model that accurately reproduces the disease's symptoms.
"This work marks the end of an almost decade-long effort to create mice that faithfully model human sickle cell disease," Pászty says.
Transgenic mice containing the human sickle genes have been engineered before, but these mice developed only mild symptoms of the disease. The problem was that in addition to carrying the mutant human genes responsible for sickle cell disease, these strains also carried normal mouse genes which counteracted the defective human genes.
"Through a series of complex transgenic and gene knock-out manipulations, we were able to add the appropriate human genes as well as delete the (corresponding) mouse genes," says Pászty. "The end products are mice with irreversibly sickled red blood cells, anemia, and multi-organ pathology. In contrast to the limited studies that can be performed in humans, these animals provide an opportunity for rapidly performing a wide range of experiments. They should play an important role in furthering our understanding of sickle cell disease and in developing improved therapies for treating sickle cell patients."
Sickle cell disease was once referred to as sickle cell anemia, but the term "anemia" was dropped because it emphasized only one manifestation of the condition. Victims inherit from both their parents a gene that makes a mutant form of hemoglobin, the iron-containing protein in red blood cells which carries oxygen from the lungs to the rest of the body.
This mutant form of hemoglobin is called "hemoglobin S."
Under certain physiological stresses, such as a decrease in oxygen, the hemoglobin S protein will polymerize, forming a rigid chain that may distort a blood cell into the shape of a "sickle." Lacking the flexibility of normal disc-shaped cells, these sickled cells are unable to squeeze through capillaries. This impairs the flow of blood, reducing the body's supply of oxygen. Damage from the reduction in oxygen accumulates, causing cell death in various tissues, most notably in the kidneys, liver, lungs, and spleen. This leads to organ dysfunction and ultimately results in death.
All hemoglobin is made up of two polypeptide chains--an alpha globin and a beta globin chain. Sickling occurs when a hemoglobin protein with a normal alpha globin chain and a mutant beta S globin chain precipitates out of solution during a state of deoxygenation.
Creation of the new sickle cell mouse model began about five years ago when Berkeley Lab researchers set out to engineer two new strains of knock-out mice: one which would no longer produce mouse alpha globin and one which would no longer produce mouse beta globin. At about the same time that Lab scientists created the knock-out mice which did not produce mouse alpha globin chains, a research group led by Dr. Tim Townes of the University of Alabama at Birmingham succeeded in creating knock-out mice which did not produce any mouse beta globin chains.
"Rather than duplicating each others' work we exchanged knock-out mice and then went our separate ways in terms of creating the human sickle hemoglobin transgenics," says Pászty. "It worked out well for both of our groups, because after the long process of breeding these three strains of mice together we both managed to create mice with sickle cell disease."
Townes and his collaborators also published a paper describing their sickle-cell-diseased mice in the Oct. 31 issue of Science magazine.
With experts predicting a worldwide surge in the incidence of sickle cell disease, the perfection of this mouse model is extremely timely. Mice are highly valued for medical research because their physiology is quite similar to that of humans, they are fast-breeding, and their small size makes them easy to maintain and handle in large numbers.
Development of the sickle cell mouse was funded by grants from the National Heart, Lung, and Blood Institute and by the National Institute for Diabetes, Digestive, and Kidney Diseases.

Berkeley Lab's Engineering Division has provided the heart of one of nine experiments aboard NASA's Advanced Composition Explorer (ACE), a satellite launched last August to study the "composition" of outer space: the solar corona, the interplanetary and local-interstellar media, and the makeup of the galaxy itself. Cosmic rays offer one of the best ways to sample the Milky Way at high energies, and that's what CRIS--the Cosmic Ray Isotope Spectrometer--was built to do.
Designed by a consortium led by Caltech astrophysicists, CRIS consists of 60 lithium-ion-compensated silicon detectors, each three millimeters thick and 100 millimeters in diameter. The Si(Li) detectors measure the total energy of incoming cosmic ray heavy nuclei and the rate of energy loss as the nuclei come to a stop. The data is combined with input from a trajectory detector of fiber-optic planes, which sits on top of the stacks of silicon detectors, to determine the mass and atomic number of each cosmic ray nucleus. CRIS is designed to observe all the stable or long-lived nuclei up through Z=30 (zinc) in the periodic table.
"Starting with ISEE-3, the Third International Sun-Earth Explorer launched in 1978, we've built similar experiments for six of the last seven satellites of this kind," says Jack Walton of the Measurement Science Group in the division's Engineering Science Department.
Each new cosmic-ray "telescope" has presented the Measurement Science Group with greater challenges in the fabrication of instruments that have to be exquisitely crafted and at the same time rugged enough to withstand the G-forces, vibration, and temperature extremes of a launch into space. The silicon detectors of CRIS are the biggest and most sensitive yet for this kind of instrument.
"Only one company in the world, Topsil, provides the kind of crystals we need," Walton says. "It's located in the village of Frederikssund on the west coast of Denmark--a place so small that when five of us went to visit the plant, the only taxi in town had to make two trips to carry us all from the railroad station."
Yu Wong, along with Julie Lee, headed the team that fabricated the detectors; he explains that the silicon used in CRIS is doped with boron, which provides negative acceptor sites in the crystal lattice. After the wafers are sliced from a single crystal of silicon by a diamond saw, they are coated with lithium on one side; with ultrasound cutters and chemical etching, grooves are cut around the top edge of the wafer and a shallow "well" is created on the bottom.
Lithium is an "interstitial donor" to silicon; by heating the wafers to 110 degrees Celsius and applying a positive 500-volt bias, the positive lithium ions are made to drift into the bulk of the crystal, positioning themselves among the silicon atoms instead of replacing them. They pair with the negative boron acceptor sites and turn the entire wafer into what Walton calls "a big silicon diode," with a net electrical impurity concentration of merely about one part in ten trillion.
The completed detectors are measured for flatness to an accuracy of better than one micrometer, calibrated using accelerated beams of argon and rigorously tested for stability under high-vacuum conditions. The 60 finished wafers in the CRIS experiment are the survivors of more than 160 candidates virtually hand-made at Berkeley Lab.
The ACE satellite is headed for a unique orbit around a gravitationally stable libration point between the Earth and the sun that will keep it operational for at least five years. As an example of the scope and sensitivity of the CRIS experiment, it is anticipated that CRIS will collect some 100,000 iron nuclei (along with dozens of other species) during its first two years in space, enough to precisely determine the abundance of even the rarest iron isotope, iron 58, which probably accounts for only three tenths of one percent of all the iron in ACE's outer-space environment.
Berkeley Lab's Engineering Science Department staff, under the leadership of Joe Jaklevic, have become specialists in supplying detectors capable of just that kind of precision and endurance.
Progress of the ACE satellite as it races towards its planned orbit can be followed on the ACE website.

In Materials Chemistry, the Lab won two of the three awards. Alex Pines was cited for Outstanding Scientific Accomplishment for his development of new concepts and techniques in nuclear magnetic resonance (NMR), such as double rotation and dynamic-angle spinning for high-resolution imaging of solids, and the application of these novel NMR methods to a wide range of materials research problems.
Paul Alivisatos won for Sustained Outstanding Research on the distinctive properties of nanometer-scale assemblages of atoms. Alivisatos pioneered the manufacture by chemical means of quantities of millions of individual atomic clusters--assemblies ranging from 100 to 10,000 atoms in size--including such compounds as gallium arsenide and other semiconducting nanoscale crystallites.
In Solid State Physics, two of the three prizes also went to Berkeley Lab researchers. Norman Phillips, who shared the award for Outstanding Scientific Accomplishment with researchers at Argonne National Laboratory, confirmed that the transition in the presence of magnetic fields to the superconducting state in high-temperature superconductors of the cuprate type--not seen in normal superconductors--is a thermodynamic first-order transition as some theorists had speculated. Philips measured latent heat at the transition and found it to be consistent with magnetization.
Yuen-Ron Shen was recognized for Significant Implication for DOE-Related Technologies for developing a general technique for studying surfaces and interfaces by means of non-linear laser spectroscopy. So versatile is Shen's technique that it can be used not only for solid structures but for liquid and biological surfaces and interfaces, as well as for processes such as catalysis.
In Metallurgy and Ceramics, the award for Outstanding Scientific Accomplishment was won by Uli Dahmen for his discovery of the "magic size" phenomenon that occurs among nanoscale inclusions of lead embedded in a matrix of aluminum.(See Currents, Oct. 17.) Only sizes and shapes that minimize strain energy can form, which helps explain the unique properties of these inclusions (e.g., their very high melting points.)
The DOE materials sciences awards are more than a pat on the back. "The
prizes are worth almost $250,000 in equipment funds for the winners," says
Mark Alper, deputy head of MSD. That's material assistance indeed to the cause
of materials sciences at Berkeley Lab.

Two Berkeley Lab researchers are among the 270 newly elected Fellows of the American Association for the Advancement of Science (AAAS), the world's largest federation of scientists.
Bob B. Buchanan, a biochemist in the Earth Sciences Division, is professor of microbial biology at UC Berkeley. Recently his work has focused on the role of the catalytic protein thioredoxin in seed germination, with implications for producing better wheat flours. A second line of research concentrates on metal detoxification and bioremediation, with an emphasis upon removing selenium from polluted waste streams.
Marvin L. Cohen, a theoretical physicist with the Materials Sciences Division, is University Professor at UC Berkeley. One of the most cited condensed matter theorist of the last 30 years, Cohen developed the pseudopotential model of electronic structure and has applied it to predicting the properties of novel materials from first principles, including hard carbon nitride, a material harder than diamond. His current interests include the electronics of carbon-60 buckyballs and nanotubes.
The AAAS was established in 1848 and has 140,000 members. It publishes the weekly peer-reviewed journal Science. Individuals are nominated and elected Fellows for their efforts toward advancing science or fostering applications that are deemed scientifically or socially distinguished, a tradition that began in 1874.
The Department of Energy's Office of Scientific and Technical Information (OSTI) has announced the launching of a new website--The DOE Information Bridge--which provides full-text access to DOE report literature. DOE employees and contractors are offered free access to bibliographic data and full text of energy-related scientific and technical research results.
The website so far includes approximately 21,000 full-text documents and 200,000 bibliographic records. OSTI plans to update the site daily with an average of 50 full text documents and several hundred bibliographic citations. In addition to DOE reports, the contents will include bibliographic citations of energy related scientific and technical information obtained through international exchange agreements, other government agencies, and other energy related sources.
The full text of about 600 Berkeley Lab formal reports, conference papers and proceedings, theses, and informational brochures submitted to the Lab's Report Coordination Office since Jan. 1996 are also available through this system.
To access the data in the Information Bridge (https://apollo.osti.gov/dds/), users must first obtain a password. To request your password, call OSTI at 423-576-8401 or 423-576-0487, or send an e-mail to firstname.lastname@example.org.
Rulon K. Linford, a 24-year veteran of the Los Alamos National Laboratory and expert in fusion research, has been appointed associate vice provost for research and laboratory programs for the University of California. Linford will oversee activities related to the university's academic and programmatic relationship with three of the DOE managed laboratories -- Berkeley Lab, Los Alamos and Livermore National Laboratories. Currently he serves as the UC coordinator for science and technology at Los Alamos. Linford replaces Carl H. Poppe, who filled the post since its inception in 1994 until his retirement earlier this year.
Director Shank said: "The LDRD program continues to be a primary means of initial support for new, innovative ideas. The proposals for FY 1998 demonstrated a broad range of interesting scientific and technological research and development possibilities." Computational proposals form an important subset of funded proposals in all scientific divisions; a number of other projects also apply Berkeley Lab's expertise at the Advanced Light Source and in the Center for Environmental Biotechnology.
In addition to cross-divisional and/or multi-investigator projects, a number of individual investigator proposals were also funded. Some of the proposals funded were VUV/soft x-ray synchrotron research for molecular environmental science; genomic-scale gene identification approach to cell phenotype; simulation and analysis for high energy and nuclear physics; laser driven particle acceleration; studies toward a large-scale neutrino observatory; investigations in boron neutron capture therapy; regional effects on global climate changes; energy efficiency and demand in industry; and new detector applications at the 88-Inch Cyclotron.
Director Shank expressed his appreciation to all principal investigators who submitted proposals for their effort and creativity.

Energy Awareness Month
Do you know what equipment in your office uses the most energy? If you guessed the copy machine, you are correct, according to information from the Environmental Protection Agency (EPA). Copiers vary widely in the amount of power they draw, depending largely on copier speed. However, most of the electrical consumption occurs when copiers are idle. The EPA estimates that seven million copiers are currently in use in the U.S. and that most of them remain idle for several hours each day.
To cut down on such energy waste, in 1995 the EPA developed a new component to its Energy Star Office Equipment program, which encourages copier manufacturers to incorporate automated power management features into their new machines. As a result, Energy Star copiers power down to an "off" mode, drawing very low power after no activity has occurred for a specified time. Energy Star copiers that fit the July 1, 1997 EPA criteria have additional controls that step down the power first to a "low-power" mode after only 15 minutes of no activity. The EPA estimates that these power management features on Energy Star copiers could reduce annual electricity costs by 60 percent.
Mary Ann Piette and Bruce Nordman, both researchers in the Environmental Energy Technologies Division, have been funded by the EPA to evaluate the field performance of Energy Star copiers. The EPA hopes to use the information to further optimize savings.
In order to measure the energy savings from Energy Star copiers, Nordman has conducted nighttime audits to see whether Lab copiers are typically turned off at night. After checking half of the copiers at the Lab, Nordman found that only five percent of the non-Energy Star copiers were switched off; one-third were fully on, and the remaining were in a "power- saver" mode. As expected, the Energy Star copiers were all powered down to their "off" mode, leading Nordman to conclude that "Energy Star copiers do appear to be saving energy."
The next step in quantifying electricity savings will be to analyze data collected from the detailed monitoring of six selected copiers at the Laboratory.
In addition to the overuse of electricity, copiers also consume a significant amount of paper--two billion dollar's worth nationwide each year. According to the EPA, it takes 10 times more energy to manufacture a piece of paper than to copy an image onto it. Yet according to estimates, double-sided copies are only made 26 percent of the time.
To analyze what strategies might change this statistic, Nordman has been measuring the use of double-sided copying at the Lab. So far, he noted that Energy Star copiers whose default is double-sided copying have had that feature disabled. On the other hand, he also found that "just putting up signs asking people to please make double-sided copies increased the double-sided to single-sided copying ratio by eight percent."
Another key issue Piette and Nordman have included in their research is user satisfaction. Later this year they will survey employees both inside and outside the Laboratory to better understand public perceptions and use of Energy Star copiers.
In the meantime, Lab employees can save thousands of dollars each year simply by making double-sided instead of single-sided copies and by turning off copiers when they are not needed.
For more information on the research being conducted at the Lab, contact Nordman at X7089 (BNordman@lbl.gov) or Piette at X6286 (MAPiette@lbl.gov). More information on Energy Star copiers can be found on the web at http://www.epa.gov/appdstar/esoe/copylist.html.
