Investigation of Rare Hereditary Disorder Sheds Light on How the Body Repairs Itself

By Jeffery Kahn

Oxidative damage has been implicated in a range of diseases including cancer, atherosclerosis, neurodegenerative diseases such as Parkinson's and Alzheimer's, and even aging. Now, life scientists believe they have linked it to Cockayne syndrome, a rare hereditary disorder in which infants suffer severe developmental failure and early death.

In recent papers published in Science magazine and the Proceedings of the National Academy of Science, the research team led by Priscilla Cooper of the Life Sciences Division provides the first evidence that Cockayne's results from mutations that prevent the body from rapidly repairing oxidative damage to DNA. In pinpointing what goes wrong during Cockayne's--a disease where normal development is severely impaired--the findings also shed new light on how vital DNA repair processes must work in order for normal development to occur.

The research team includes Steven Leadon of the University of North Carolina, and Stuart Clarkson and Thierry Nouspikel of the University of Geneva Medical Center in Switzerland. Leadon was an LSD staff scientist at Berkeley Lab from 1985 to 1991.

Currently, there is no treatment for Cockayne's. Babies born with this syndrome appear fairly normal at birth, but fail to develop normally. During their short lives, they become dwarfed and have other skeletal abnormalities. Though they are profoundly retarded, these children typically are very friendly and very interested in people. In most cases, they die in infancy or childhood.

Up until now, the prevailing theory has been that Cockayne's is due to subtle defects in transcription. That is, scientists believed that these children's genetic machinery for synthesizing proteins needed by the body does not operate at normal capacity. Over time, the theory says, this results in developmental failure and death.

The Cooper team has found a different explanation, focusing on how the body deals with the repair of oxidative damage.

Every minute, the body pumps 10 to 20 liters of oxygen through the blood, carrying it to billions of cells in our bodies. In its normal molecular form, oxygen is harmless. However, cellular metabolism involving oxygen can generate several highly reactive forms of oxygen, called free radicals. These free radicals can cause oxidative damage to cellular components, including the DNA.

In an average human cell, several thousand lesions occur in the DNA every day. Many of these lesions result from oxidative damage. Each lesion--a damaged section of DNA--must be snipped out and the DNA repaired to preserve its normal function. Unrepaired DNA can lose its ability to code for proteins. Mutations also can result. These mutations can activate oncogenes or silence tumor suppressor genes.

Normal cells efficiently recognize and repair damaged sections of their DNA. In fact, Cooper and her colleagues have found that the repair of oxidative damage occurs faster in active genes (which make up less than five percent of the genome) than in inactive regions of the DNA. In the case of children with Cockayne syndrome, Cooper says, these latest findings establish that oxidative damage to active genes is not preferentially repaired, and in the most severe cases, repair is slowed throughout the whole genome. The resulting accumulation of oxidative damage could impair the normal functions of the DNA and may even result in triggering a program of cell death (apoptosis).

"We have not yet proved this is the case," Cooper says. "However, we have shown a very strong correlation between the inability to repair oxidative damage and severe developmental failure and early death. We believe that the inability to repair oxidative damage is the underlying cause of Cockayne's."

Cooper says one novel implication of the research is that two repair mechanisms thought to be independent of one another appear to work together to repair oxidative DNA damage.

Nucleotide excision repair (NER) removes many types of DNA damage, including lesions produced by chemical carcinogens or sunlight, either of which can cause cancer if not repaired. This repair process is general in nature, snipping out defective stretches of DNA that consist of some 30 nucleotides. The process is initiated not because of the recognition of a specific defect but because of the detection of a general distortion produced in the DNA helix by lesions. Until now, NER was thought to be the only repair process that can select the transcriptionally active portion of the genome for preferential repair.

In contrast, base excision repair (BER) relies on specialized enzymes to recognize and repair very specific types of damage, including the damage produced by free radicals. This process cleaves and repairs a section of DNA consisting of one to five nucleotide bases.

After tackling what amounts to a mind-twisting scientific brain teaser, Cooper's team reached the conclusion that NER and BER work together to repair oxidative damage.

Cockayne syndrome can result from defects in any of five separate genes. Different defects in three of these genes can cause another disease called xeroderma pigmentosum (XP), which is not clinically related to Cockayne's. Individuals with XP, which is known to be a repair-deficiency disease, are extremely sensitive to ultraviolet light and chemical carcinogens, and are highly susceptible to skin cancer.

To solve the puzzle, the research team focused on the XPG gene, one of the genes that can result in either of the two diseases. It is among a family of seven genes, all of which are necessary for NER, and any one of which, when defective, can result in XP. As reported in Science, the team showed that oxidative damage is removed normally by BER from the cells of XP patients who have NER defects only, but not from those patients who have Cockayne's due to defects in the XPG gene. Thus, they concluded, one normal function of the XPG gene is to play a role in the removal of oxidative lesions by BER. The researchers report that some mutations in this gene destroy its ability to function in NER, thus causing XP. Different mutations also destroy its ability to direct efficient removal of oxidative damage by BER, and result in Cockayne syndrome.

Currently, Cooper's group is investigating what goes wrong with BER in Cockayne's patients. Eventually, resolution of this biochemical conundrum could have medical and pharmaceutical implications not only for children born with Cockayne syndrome but for those afflicted with other repair-deficiency disorders.

In-House Energy Management Program Saves Lab Millions

By Allan Chen

Technologies developed at Lawrence Berkeley National Laboratory's Center for Building Science have helped energy users in the United States and throughout the world save energy since the 1970s.

To save energy and money by applying energy-efficient technology and practices in its own facilities, as well as set an example for the rest of the world, Berkeley Lab launched an energy-savings program in 1985. The efforts of the In-House Energy Management Program (IHEM) have led to an annual savings of $2.3 million in energy costs at Berkeley Lab. Additional benefits include reduced maintenance from capital equipment improvements (far surpassing federal energy use reduction goals for government agencies), decreased pollution, improved worker productivity, and the dissemination of knowledge about energy-efficient technologies.

Success at Home

"IHEM meets its energy-saving objectives by first performing studies to identify energy-efficiency retrofit projects, and then managing the retrofit projects that are found to be cost-effective," says IHEM section chief Doug Lockhart. Since 1985, the organization has conducted more than 40 studies on Berkeley Lab facilities. Between 1990 and 1995, IHEM implemented 27 projects that collectively saved an estimated 94,250 million BTUs--more than 28 percent of the Lab's annual energy consumption before the retrofit.

"Since 1985, IHEM has reduced the Lab's energy use by 41 percent through the 1996 fiscal year," says Lockhart. "This figure exceeds a federal goal for all agencies to reduce their energy use 7 percent within the same period." Berkeley Lab's utilities cost $3.86 million in the 1995 fiscal year. The programs managed by IHEM are saving the Lab $2.3 million per year.

In addition to two architecture and engineering firms, IHEM also draws on the Center's many researchers in energy-efficient technology and program design. This cooperation led in 1994 to the creation of the Applications Team, a joint venture intended to speed the deployment of energy-efficient technologies and financing programs in markets throughout the U.S.

IHEM's numerous retrofits span the full array of available energy-efficient technologies. Berkeley Lab's wide variety of buildings ranges from temporary office trailers, to specialized laboratory buildings, to large multilaboratory structures with complex lighting, HVAC, and energy requirements. IHEM's efforts have included lighting, motor, and HVAC retrofits; chiller upgrades and replacements; and the installation of variable-speed drives and improved energy monitoring and control systems (EMCS).

One example of the program's willingness to adopt a new technology is its push toward more energy-efficient lighting. "IHEM standardized the Lab on T-8 fluorescent lighting and installed it throughout the Lab when it was still an emerging technology," says Lockhart. In a retrofit of emergency exit signs, IHEM adopted LED signs that are up to three times as efficient as their incandescent counterparts.

In the area of controls engineering, IHEM engineers oversaw the installation of an EMCS with more than 8,000 monitoring and control points, with another 2,000 to be installed. All research at the Lab that requires HVAC controls, laboratory pressurization, and central plant equipment is tied into this system, which optimizes energy use and maintains energy services at a high level of quality. The group also analyzes utility bills to ensure that the Lab's energy charges are accurate, and manages an employee energy-awareness program.

Environmental Benefits

In addition to the energy benefits of IHEM's work, there are other environmental benefits. For example, eight retrofit projects completed in 1996 saved more than 16 million kWh in energy annually and reduced the emissions from fossil-fuel power plants by 8,200 tons of carbon dioxide, 9,000 tons of sulfur dioxide, and 12,300 tons of nitrogen oxides. Replacing an old chiller with new, efficient technology also reduced the CFCs in use at the Lab, and a refrigerant recovery program helped ensure that refrigeration equipment was well maintained, to prevent CFC leakage.

Future Plans--Working Outside the Lab

As the number of new opportunities to save energy at Berkeley Lab decreases, IHEM staff members are focusing more on the outside world through the Applications Team. These projects include developing an energy measurement and verification protocol, retrofiting the federal building in San Francisco, developing a design guide for energy-efficient labs, and collaborating with the Federal Aviation Administration and the National Park Service.

"With the terrific support we've had from the DOE IHEM program, and now from the Federal Energy Management Program, we are in a unique position to leverage our expertise in ways that will effect a reduction in federal energy use nationwide," Lockhart says.

UC, Affiliated Labs First in Research Leading to U.S. Patented Inventions

The University of California and its affiliated national laboratories produce more research leading to patented inventions than any other public or private research university or laboratory, according to a study for the National Science Foundation (NSF).

UC research published in scientific journals was cited as a basis for a U.S. invention in 3,125 instances during fours years in which patents were examined by the NSF study. The study is, according to the NSF, the most thorough examination of the scientific foundation of American patents and shows that publicly financed science lies at the heart of most commercial innovations.

"This is another excellent indicator of just how well the University of California does when compared to other research institutions," said UC President Richard C. Atkinson, "and how powerfully university research drives the economy."

The NSF study, which ranked the top 25 most frequently cited research institutions, showed that when the research was broken down by topic, UC campuses had 2,106 citations in biomedical papers, 288 in chemistry, 483 in physics and 248 in engineering and technology.

After the citations were totaled by individual campuses among the top 25 research universities, UC San Francisco ranked fifth in biomedical references with 930, UCLA was ninth with 642 and UC San Diego was 13th with 534.

In chemistry, UC Berkeley ranked fifth with 139 references, UCLA was 15th with 74 and UC San Diego was 24th with 65.

In physics, UC Santa Barbara was ninth with 110 citations, UC Berkeley was 11th with 100, Lawrence Livermore Lab was 17th with 80, Berkeley Lab was 19th with 74, Los Alamos Lab was 22nd with 63 and UC San Diego was 25th with 56.

In engineering and technology, UC Berkeley was third with 189 references and UCLA was 14th with 59.

Other U.S. author institutions that placed high were AT&T Bell Labs, which was first in both physics and engineering and technology, Harvard University, which was first in biomedical and third in chemistry, and MIT, which was first in chemistry and in the top seven in all other categories.

In the ranking for number of citations among top U.S. support agencies, the Department of Energy ranked third in three out of the four categories, and 15th in biomedical.

The study, conducted by CHI Research Inc. for the NSF, found strong evidence that publicly financed scientific research funded by the federal government or nonprofit agencies at both public and private research universities and laboratories plays a surprisingly important role in breakthroughs and inventions produced by private industry in the United States.

The study concluded that publicly financed science research was cited 73 percent of the time in research papers leading to patents as the basis for the discovery or innovation. Private companies paid for the rest of the patent research.

CHI examined the science references on the front pages of U.S. patents during four years, 1987, 1988, 1993 and 1994, looking at all 397,660 patents issued. It is, according to the NSF, the most thorough examination of the scientific foundation of American patents and shows that publicly financed science lies at the heart of most commercial innovations.

DOE/UC/Labs Partnership Program Recognized in Government-Wide Study

The government-wide Benchmarking Study on Performance Measurement Systems has selected the DOE/University of California/National Laboratories "Partnership for Performance" as a candidate for identification as a best practice partner. A site visit conducted on May 13 concluded that the effort among DOE-Oakland, DOE-Albuquerque, UC, and its three national laboratories (Berkeley, Livermore, and Los Alamos) warranted inclusion in the final report. The study was an outgrowth of Vice President Al Gore's National Performance Review.

The study will cite 30 "partners" who can be contacted as exemplary models for performance measurement. Only two governmental agencies will be represented: DOE (by this effort) and the Veterans Administration. The other 28 partners will be from U.S. industry.

The process for being named a partner included a screening by questionnaire, phone interview and a follow-up site visit for organizations that met or exceeded threshold criteria. The criteria for inclusion of a partner included consideration of whether an organization was involved in customer and stakeholder inputs, continuous improvement initiatives, benchmarking, balancing cost against performance, use of accountability systems and integration into strategic planning.

New Position for Ritchie

Robert Ritchie, head of the Structural Materials Department in the Materials Sciences Division and a UC Berkeley professor, has been elected president of the International Congress on Fracture. The Congress, which is the premier organization worldwide governing the study and application of fracture--with delegates from more than 50 countries--made the election at its quadrennial meeting in Sydney, Australia, in April. Ritchie will serve a four-year term ending in 2001.

Silverman Named to AAAS Post

The American Academy of Arts and Sciences has appointed Paul H. Silverman executive associate of its Western Center. Silverman is the former associate director for Life Sciences at Berkeley Lab. In his new appointment, Silverman will have the responsibility to develop studies, projects and activities--utilizing the scientific and scholarly resources of Academy members in the West--that are aimed at promoting the understanding of the needs and problems of the world of learning and of society. The Academy, founded in 1789, honors achievement in sciences, scholarship, the arts and humanities, and public affairs, and conducts a varied program of projects, studies and publications responsive to the needs and challenges facing society.

During Silverman's tenure at Berkeley Lab, he directed the UC Systemwide Biotechnology Research and Education Program. In addition to other prestigious positions, he served as associate chancellor at UC Irvine, in charge of the Center for Health Sciences from 1994 until his retirement in 1996.

Computer Scientist Takes Telecommuting to Great Lengths

By Jon Bashor

As a Lab computer scientist working with the Energy Sciences Network, Joe Metzger knows all about sitting in one place and working in another via computer networks.

In fact, for Metzger, telecommuting isn't just a nifty idea--it's a way of life.

Three weeks out of every month Metzger drives a short distance to his office at a national laboratory and hooks up to Berkeley Lab via ESnet, thereby saving a 1,618-mile commute--each way.

Though a Lab employee, Metzger lives and works in Ames, Iowa, in the Ames Laboratory on the Iowa State University campus. Ames is one of more than 30 major DOE institutions linked to each other and to other sites around the world by ESnet.

"The group I'm in manages higher-level information services, much of it by remote access," says Metzger. "You can manage it from down the hall, which isn't a lot different from managing it from half-way across the country."

As a member of the Network Information and Services Group with the Energy Sciences Network, or ESnet, one of Metzger's jobs is postmaster for the worldwide data communications e-mail system. It's a job that lends itself well to telecommuting, which is one of the reasons he accepted the position in January.

Last summer, Metzger interviewed for several jobs in Computing Sciences here, and even went so far as to talk with a real estate agent. That's when sticker shock hit.

To get a home in the Bay Area comparable to his home in Iowa, Metzger figures he'd have to spend up to $500,000. Cost aside, living in Iowa means his kids get to see their grandparents more often.

"That was one of the big things, we wanted to be closer to family," he says. "We also enjoy the slower pace of life there."

Ames is a town of about 50,000 people, which includes 20,000 university students. While his commute from the outskirts of town is usually easy, Metzger admits he sometimes hits a jam.

"During rush hour, which is from 8:50 to 8:55 a.m., sometimes I have to wait through two stoplights," Metzger says with a smile. "It turns my five-minute commute into a seven-minute one."

Telecommuting isn't a new idea for ESnet and there is a dedicated telecommuting center in Livermore for Berkeley Lab employees who live in the Central Valley. In fact, Metzger's group leader, Allen Sturtevant, telecommutes up to three days a week, two of them from the Livermore telework center.

Sturtevant cites the ability to telecommute as an incentive to join the staff at Berkeley Lab when ESnet moved here from LLNL. "This way I get to spend more time being a real dad, attending soccer games and playing with my kids," he says.

Jim Leighton, the head of ESnet and leader of the effort to get Metzger on staff, said the remote-work option can be a strong suit in the very competitive recruiting game. In fact, Metzger turned down the job before the option of working from Iowa emerged.

Sturtevant said about 60 percent of the ESnet staff regularly telecommutes from one to three days a week, many of them from the telework center, and he hasn't noticed any drop in productivity. Even when the group worked all together in Livermore, they usually communicated primarily by e-mail.

Each week, each ESnet staff member logs into a web-based locator, noting where he or she will be each day that week, Sturtevant said, making it easy to reach everyone.

Metzger, who worked at Ames Lab for four years before joining Berkeley Lab, is still in the same office on the Iowa State campus.

"I think people here (Berkeley Lab) are getting adjusted to the idea that I'm not just down the hall," Metzger said. "But we hold weekly group meetings and monthly staff meetings by videoconference."

Metzger says his situation has drawn some inquiries and comparisons.

"Some of the people here tell me how they occasionally like to work one day at home because there are fewer interruptions," he said. "I can work for days in Iowa with very few interruptions."

Mail Room Operations Assigned to Outside Vendor

By Monica Friedlander

Starting June 16, responsibility for the mail service to the Laboratory will be transferred from the Lab-operated Mail Room to an outside vendor. Berkeley Lab management took this significant step in an effort to improve the mail service to employees while reducing costs to the Laboratory.

No Mail Room career employees will be laid off as a result of the change. Rather, they will be reassigned to other positions within the Facilities Department.

"This is good business for us," said Fred Lothrop, support services manager for the Facilities Department. "It's a sound economic decision and a step forward for the Laboratory."

Two key factors played into the decision to outsource mail services, Lothrop said. Over the past year, the U.S. Postal Service has introduced significant reforms that have drastically increased its reliance on automation. As a result, organizations that operate in a way that facilitates the handling of envelopes by machines instead of people were granted postage discounts. Unfortunately, the Lab Mail Room had no experience in this area. "We wanted to get someone who is instantly familiar with USPS rules," Lothrop said, "instead of having to retrain the entire staff."

Furthermore, he said, the Lab is not an expert in mail handling. An organization that specializes exclusively in mail service operations is bound to run them more efficiently. "This is not the fault of the Mail Room personnel," Lothrop said. "But there comes a time when it makes sense to get hold of experts in the field. When you want bread, you go to the bakery. The same principle applies to mail service."

The change will have no immediate effect on the way mail is being delivered and picked up at the Lab. The mail operation will continue to be run out of the same location on the Hill (Bldg. 69), on a similar schedule. Over time, Lothrop expects to see improvements, particularly in the turnaround service and reduction in number of misdeliveries.

Services now handled by the Shipping Department (including priority mail and packages) will not be affected by the change.

The new vendor, Pitney Bowes Manage-ment Services, was selected based on competitive bidding. The four selection criteria were: approach to providing mail service (including equipment used), personnel qualification and experience, postal performance history, and cost. A national company with a long standing track record in mail service, Pitney Bowes also holds the distinction of having pioneered the postage meter.

The new Mail Room manager will be Rick Ferguson, and he can be reached at X2209. The general Mail Room telephone number remains the same (X5353).

MicroWorlds Makes Materials Sciences Fun for All

Interactive website brings together students, scientists

By Monica Friedlander

Have you ever wondered what makes bulletproof vests bulletproof? Or how materials as different as diamonds and the graphite used in pencils can made of the same element?

The answers to these and many other questions are waiting to be found in "MicroWorlds," a web-based interactive educational "magazine" for high school students and teachers. Created by the Lab's Technical and Electronic Information Department (TEID), MicroWorlds focuses on materials sciences research being conducted at the Advanced Light Source (ALS). The site seeks to engage students in challenging activities that help them unlock the mysteries of materials they encounter in everyday life, and hopefully, to also spark a lasting interest in science.

"There are other interactive sites out there, and there are educational sites," says Jane Cross of the ALS/TEID team. "But what makes MicroWorlds unique is that its puts the two together. Students learn not just by reading on the web, but by figuring out puzzles and putting in some effort. It's a step by step process."

Conceived in 1994, MicroWorlds went online in January 1995 as a pilot project created by TEID with the help of local high school teachers and students. Its aim was to demonstrate the feasibility of publishing electronic instructional materials on the web, while also making the work at Berkeley Lab accessible to the outside world.

The project caught on quickly, with more than 100 new teachers and students registering each month. MicroWorlds provides a curriculum that has been adopted by educational institutions around the world. Ascension College in Australia, for example, uses the site as part of its curriculum for senior science students. Earlier this year the web site received the Platinum Award from NetGuide Live, a web-based guide to the internet.

"I believe one key reason for the success and recognition of Microworlds is that it is a team effort, combining the talents and expertise of many groups," says Cross. "Teachers and students helped define its original content and continue to do so. The illustration group created its eye-catching graphics, the photo lab helped us put up a virtual reality page of the experiment floor, and the editing group combined all the parts in to an integrated informative web-based magazine."

Lab webmaster Jeffery Kahn says much of the credit for Microworlds goes to former TEID editor Gloria Lawler. "This was a labor of love for her."

In addition to research guides and curriculum materials, MicroWorlds provides a variety of fun features, such as puzzles, a virtual tour of the ALS, a variety of hands-on-activities (such as building cubes and pyramids out of straws to help students understand molecular structures), and biographies of ALS staff people.

Entitled "The Bright and the Busy," the biographies are a key feature of MicroWorlds. The feature acquaints students with real-world scientists, teaches them about possible careers, and allows them to interact on a personal level with Lab staff. What's more, the biographies are written by students. The original design and first biography was initiated by Andy Macfie of University High School in San Francisco.

Waste Watchers

DOE Considers "Chargeback" for Waste Generators

The Department of Energy intends to change how it handles waste management funds. One way would be to return financial responsibility for waste management to the scientific organizations responsible for conducting the research. This change may result in more efficient waste management within DOE, and provide incentives for additional waste reductions at facilities such as Berkeley Lab. The incentives come primarily from returning savings that result from waste reduction to the waste generators.

DOE may transfer the responsibility for direct costs of waste management at Berkeley Lab to the waste generating organizations as early as FY2000. To prepare for this possibility, the EH&S Waste Management Group has initiated a generator cost awareness program and has distributed divisional waste management statements covering the first quarter of FY97 to each division director. A second set of statements, covering the second quarter of FY97, will be distributed in early June.

Each principal investigator should examine these statements to become familiar with the direct costs of waste management at Berkeley Lab. Further information on the proposed DOE "Chargeback" program will be distributed through this column. If you have questions or comments, Waste Management would like to hear from you. Please contact Anne Kumaranayagam (X4962) or Brian Smith (X6508).

Recap of Earth Month Activities

As you read in the last issue of Currents, the April 1997 Earth Month activities, focusing on water and water-related activities, were a big success. Among the activities were tours of EBMUD, Strawberry Creek, and the San Francisco Bay Model in Sausalito, a Berkeley Marina beach cleanup, a litter cleanup, and special guest lectures. As in the past, the EcoFair was the most attended event.

Earth Month activities are brought to you by the Waste Management group, which hopes you enjoyed them. Thanks to all who participated. Anyone wishing information about events or speakers should contact WM's Shelley Worsham (X6123), this year's coordinator.

Waste Pick-up Times Normal Again

The new Waste Management Facility (Bldg. 85) started operations on April 21. As was communicated to waste generators, traditional services, especially waste pick-ups, were likely to be a little slower than normal as Waste Management staff moved waste from the old facility down to the new facility. The waste permit requires that this be done fairly quickly after start-up. That move and other transitions are nearly complete and waste pick-up times should return to normal (i.e., within seven working days of receiving your faxed waste requisitions). Contact Michelle Flynn (X5877) or your generator assistance specialist if you have questions or concerns.

The University of California recently concluded the purchase from PG&E of the Grizzly Peak electrical substation near Bldg. 77. The purchase will allow the University to obtain better power rates and to expand the capacity of the substation.

The agreement with the Laboratory, which also receives power from Grizzly Peak, requires the University to upgrade the existing substation for Laboratory use. In return, the Laboratory has agreed to vacate land adjacent to the substation to permit the University to build a new substation to provide the campus with power.

The campus program calls for the start of construction in early 1998. The Facilities Department will have the area cleared and ready for that work by December 1997. Clearing the area means relocation of the Property Reuse Center and demolition of Bldg. 42.

After an extended feasibility study, it was decided that the most cost-effective and least disruptive alternative for relocating the Property Reuse Center was to move it to the Lab's warehouse, Bldg. 903. This will provide more space for the center and allow consolidation of the Salvage and Property Reuse functions in a single location.

The Property Reuse Center will remain operational at its present location through Friday, July 18. Visitors between now and then are invited to add their names and mailstops to the center's mailing list. The center will reopen in Bldg. 903 on August 1.

Employees looking for surplus materials will be welcome to browse at Bldg. 903. Meanwhile, ways to minimize the impact of this move on browsers will be explored.

Information about the move will be posted on the Web through the Property Home Page. You may also contact Monte Clevenger (X4587) for more information.

Correction

As reported in the May 16 issue of Currents, the Lab's procedures for ordering cylinder gases have changed. The new procedures were outlined in a May 21 informational meeting, and described in Currents. Please note that the handout distributed at the informational meeting contained an incorrect fax number for placing orders. It was also incorrect in the Currents article. The correct fax number is 652-6513.
