As I take stock of our progress in this area, the picture that emerges is not a comfortable one. Earlier this week at the Diversity training session I pointed out that we are not yet in a position to call ourselves a leader in creating a diverse work environment. I believe we can do much better. Our goal should be to set an example for the rest of society.
Over the last eight years, minority representation in the workforce has not budged from a level of about 26% and female representation has been stuck at around 31%. Whatever we have been doing, we have not changed the makeup of our laboratory.
So how do we change things for the better? The first thing to do is to raise the level of dialogue and attention to this topic, and for the last several months I have been having extensive discussions with the Division Directors. I have also benefited from talking with members of Berkeley Lab's Diversity Committee. Among the conclusions I have reached is that all of our divisions must be part of the solution. Starting this year I am asking that each division create a Diversity Plan to advance the cause of diversity. I will review these plans with the help of Deputy Directors Pier Oddone and Klaus Berkner.
A division's Diversity Plan should address two main elements that are closely tied together. First, we should take innovative actions to enhance the work environment for all our employees. The greatest recruiting tool for expanding our diverse work force is an employee who feels well supported. Second, we should take steps to ensure that our hiring pools are as diverse as possible. Toward this end, the Human Resources Department has established a new recruitment office to support divisions in developing diverse hiring pools.
I invite you to contribute your thoughts and ideas to your Division Director in order to make these plans effective tools for advancing the cause of workforce diversity.
Of course, we need to continue our efforts to expand the pipeline of minority students in education and with access to our Laboratory. Our school-to-work program and increased participation by our staff in mentoring community college and undergraduate students contributes as well to our work environment.
I thank you all in advance for joining me in this recommitment to making our Laboratory a shining beacon of which all parts of our community can be proud. It is a privilege to be a part of an institution like ours. We must strive to be inclusive of all the elements of the society that supports the work we do.
Come for the science and stay for the fun
Mark your calendars for Saturday, May 6, to take part in Berkeley Lab's Open House and Science Festival. This year's event promises to be better than ever, with a variety of new attractions and special activities. The day kicks off at 10 a.m., and will feature hands-on science, a job fair, food, music, and--as those of you know who have attended previously--more than you can possibly see and do during the six-hour event.
Our festival this year will include multiple attractions for Bay Area students of all ages, as well as their parents. Among the special events is a very special preview screening of Michael Apted's film, "Me & Isaac Newton," a celebration of the lives of seven exceptional scientists, including Berkeley Lab's own Ashok Gadgil. Also, in the spirit of the Lab's longstanding mission to support science education, there will be an event honoring local science and math teachers who have served as an inspiration to their Bay Area students.
This year's Open House will focus on four theme areas: Home and Environment, To Your Health, World at Your Fingertips, and Universe in Your Pocket, along with the always popular Family Science Tents for children from preschool through elementary school. There will be tours of the Advanced Light Source, the National Center for Electron Microscopy, and the 88-inch Cyclotron, along with an amazing array of demonstrations and exhibits that bring to life the Lab's mission of scientific exploration. For a complete description of Open House themes and activities see pages 4 and 5 of today's Currents. Plan out your visit in advance, and bring your family and friends for a day full of wonder and discovery.

A team of Berkeley Lab and UC Berkeley scientists have reported the first direct observations of what happens when the message of a gene is read during the actual transcription of a single DNA molecule.
Using a unique experimental setup they designed themselves, the researchers followed transcription by single molecules of RNA polymerase (RNAP), the enzyme responsible for reading the genetic message in humans and other higher organisms as well as in bacteria. Their observations provide new insights into how genetic expression in cells may be regulated.
Carlos Bustamante, a biophysicist and UC Berkeley professor who heads the Advanced Microscopies Department for the Physical Biosciences Division, led the group that published the results in the March 31 issue of the journal Science. In addition to Bustamante, the authors were John Davenport and Gijs Wuite of UC Berkeley and Robert Landick of the University of Wisconsin at Madison.
Most of what we know about how the genetic messages stored within the DNA of a living cell are transcribed by the RNAP enzyme comes from "bulk experiments" performed on batches of molecules. Conclusions were based on averaging observations as if the activity of each molecule in the experiment were the same--an iffy assumption, given the size and complexity of an enzyme like RNAP.
The Berkeley team made their observations using an "integrated laser trap/flow control video microscope," which was designed and built in Bustamante's laboratory. In this setup, a strand of DNA is tethered between two micron-sized polystyrene beads in the middle of a chamber, one bead anchored on the tip of a glass pipette and the other held by a laser beam in an optical trap. Controlling the exchange and flow of liquids through the chamber and manipulating the laser trap can then be used to apply force on the beads, and the results can be measured through video microscopy.
This unique experimental system enabled the researchers to make direct observations of the RNAP transcription process in real time over a long length of DNA (more than a thousand base pairs). Their spatial and temporal resolution was better than previous efforts, and they could record transcription events not only as a product of solution conditions but also as a function of applied force.
It was known that RNAP might pause during the transcription process at various points along the way for a few seconds or a few minutes. Transcription may even stop entirely, with the RNAP going into a state of arrest. In their Science paper, the Berkeley researchers report that the rate at which RNAP transcription took place would vary, but the variations were not associated with specific locations along the DNA. Rather, individual RNAP molecules would switch back and forth from transcribing at a faster or slower rate -- as if, Bustamante says, "they exist in different gears corresponding to different functional or dynamic states."
It was also observed that RNAP molecules transcribing at a faster rate are less likely to pause than those transcribing at a slower rate. The authors say this suggests there is a "kinetic competition" between transcription and pausing, which would mean that pauses are not intermediate steps in the transcriptional process but are a separate functional state that renders the molecule incapable of further transcribing.
Explains Bustamante, "Our observations are consistent with the idea that a paused RNAP molecule is not just stopped there, like at a traffic light, but has parked inside a garage and must be brought out of the garage to resume its movement."
Bustamante and his colleagues speculate that within a cell there may be other molecules that bind to the RNAP to stabilize its conformation, so that it transcribes at a faster or slower rate -- which in turn would make it more or less susceptible to pausing. This, they say, could be the basis for yet another level of transcriptional control and regulation. Future experiments are planned using an improved second-generation version of the integrated laser trap/flow control video microscope, now being built.
Rosenfeld, 73 is the director of the Center for Energy and Climate Solutions, a non-profit agency in Annandale, Virginia. From 1994 to 1999, he was the senior advisor to the Assistant Secretary for Energy Efficiency and Renewable energy at the U.S. Department of Energy in Washington, D.C. From 1955 to 1994, Dr. Rosenfeld was founder and director of Berkeley Lab's Center for Building Science, and a professor of physics at the University of California, Berkeley.
At Berkeley Lab, Rosenfeld worked with the Nobel Prize winning group led by Professor Luis W. Alvarez until switching careers in the early 1970s to study energy efficiency. He was the founder of the California Institute for Energy Efficiency and was co-founder of the American Council for an Energy-Efficient Economy. He received the Star of Energy Efficiency Award in 1995, an award for outstanding contribution in promoting energy efficiency.

The report is somewhat critical in noting that lighting control technologies and systems are not standardized and that research is not coordinated in the basic science of commercial light sources, making it difficult to achieve major breakthroughs in lighting performance and efficiency. The full report can be viewed at http://www.eren.doe.gov/buildings/vision2020.
"I remain deeply disappointed at the manner in which these problems were
handled," said the Secretary in a press statement. "But I am also convinced
that the underlying science of the NIF remains sound."
Hoffman's distinguished career in nuclear science began inauspiciously enough in 1946, while she was an undergraduate at Iowa State University. There she took a course in chemistry for home economics taught by "a wonderful woman professor named Nellie Naylor." The following year Hoffman was introduced to nuclear chemistry.
"We had a 68 MeV (million electron volt) synchrotron that was just being finished there," she says, "and so we could go and do experiments and find new isotopes. You had the thrill because you were seeing something that nobody had seen before!"
Hoffman switched her major from applied art to chemistry and never looked back.
Hoffman is now an internationally recognized expert in the study of transuranic elements -- chemical elements heavier than uranium -- and after nearly 50 years in the field, she still gets a thrill from her work.
"One of the reasons I don't really want to retire is that it's a very exciting time for both the nuclear and the chemical aspects of nuclear chemistry," she says.
This past summer, Hoffman was a member of the team that discovered elements 118 and 116. She called this discovery "one of the most exciting of my career" because the radioactive decay patterns of 118 and 116 provided strong support for the existence of the "island of stability" that theorists have long predicted for superheavy elements.
Hoffman also continues to enjoy teaching. "The more people you can teach about these things, the better educated the general public will be," she says.

Berkeley Lab has taken several recent actions to answer questions involving the use of tritium in Laboratory research, in cooperation with the Berkeley community and the U.S. Environmental Protection Agency (EPA).
In order to address local concerns about the potential impacts on public health from radiation produced in scientific investigations, Laboratory Director Charles Shank has initiated the following:
The Task Force will hold its third meeting on April 25 with special focus on a draft comprehensive sampling plan for measuring tritium in the environment. This plan will gather data that the EPA can use to evaluate the Laboratory's eligibility for EPA's National Priority List. Though all data gathered to date indicate the Laboratory is well within all federal and state public health standards, the EPA has requested additional measurements.
At the first meeting of the task force members in January, Shank told them, "The issue before us is, is there an imminent health danger in this community (from Laboratory tritium emissions)? We will provide data, conduct real measurements, and get the information for you. We will cooperate with all city and regulatory bodies."
For some time now, certain community representatives and city officials have expressed concern about the very small amounts of tritium that are emitted through research activities at the Lab's National Tritium Labelling Facility (NTLF). The NTLF conducts biochemical studies to create new radiotracers to analyze biological reactions at the cellular and molecular levels.
The Task Force was formed to engage community stakeholders in the process of tritium sampling and its evaluation so that concerns about public health can be answered. A 1997 Health Risk Assessment conducted by the Laboratory, based on the Lab's own monitoring, has shown that annual air emissions from the NTLF result in off-site radiation doses that are less than two percent of the EPA's acceptable public health standard.
In response to community concerns, however, the City of Berkeley hired Franke, of the German environmental consulting firm Institut fur Energie und Umweltforschung (IFEU), to do an analysis of all reports and data concerning tritium and radiation exposure. In recent meetings at the Laboratory, Franke conveyed his needs, and Laboratory staff began the process of collecting requested information.
Hoffman, President of SENES Oak Ridge, Inc., Center for Risk Analysis, of Tennessee, brings more than 25 years of experience as an environmental scientist specializing in human dose and risk evaluation for radionuclides and chemicals to his consulting role for the Lab. Hoffman will work with Franke on data collection and interpretation.
Thomas earned his reputation as a pioneer in the field of radiation safety for particle accelerators. He recently chaired a Joint Task Group of the International Commission on Radiological Protection and the International Commission on Radiation Units and Measurements to produce a definitive report on radiological protection against external radiation.
Thomas worked at Berkeley Lab from 1963 to 1991 and served as Director of the Occupational Health Division, monitoring the operations of the Bevatron, Berkeley's historic synchrotron whose accomplishments over four decades led the frontier in the fields of high-energy and heavy-ion physics. Early discoveries at the Bevatron - or Bevalac, as it was called after its linkage with the SuperHILAC linear accelerator in the 1970s -- resulted in four Nobel prizes.
In accelerators such as this, the energizing of protons results in the emission of radiation in the form of neutrons.
In his analysis of historical radiation doses at Berkeley Lab, Thomas relied on public laboratory reports that showed the maximum potential annual dose off-site reached 820 millirem in 1959 when the maximum federal public safety standard was 1,500 millirem per year. His subsequent recalculations, based on modern conversion methods, have placed that 1959 figure at approximately 360 millirem.
Largely due to added shielding around the Bevatron, maximum potential doses in subsequent years dropped significantly, even as the beam intensities of the accelerator were increasing. The public records show that the annual measured radiation doses continued falling to below 10 millirem. Through the entire period of accelerator operations, maximum potential Laboratory radiation dose levels have always been below the federal safety limits in effect at the time, according to data in the historic published reports. Today's federal EPA safety standard for radiation from all sources is 100 millirem per year.
In 1999, site-wide, the Laboratory had a total maximum potential dose exposure at its perimeter for radiation from all sources of less than 1 millirem, which is substantially less than the effective dose equivalent received from a single dental x-ray (10 millirem).
Thomas' analysis, and the published reports from which his analysis was drawn, have been forwarded to Franke for his review.

A bright, tightly focused beam of infrared light from the ALS's beamline 1.4.3 allows researchers to follow subtle chemical and molecular changes in individual human cells, without killing the cells or using intrusive probes.
Traditional methods of biomedical research require killing cells (fixing them), averaging results from many cells, or introducing dyes, tagged proteins, or other agents that can affect cell chemistry--methods that involve tedious preparation and long delays between experiment and result.
Holman and her colleague Michael Martin of the ALS described the technique, known as Synchrotron Radiation-Based Fourier Transform Infrared spectromicroscopy, at recent meetings of the American Chemical Society and the American Physical Society.
Despite the jawbreaking name, the principle of SR-FTIR spectromicroscopy is straightforward. Different molecular and physical states of a cell absorb different wavelengths of infrared light, yielding unique spectra that can distinguish different cell types, different phases in the cell cycle, and different chemical reactions and physical changes inside the cell.
Light from the infrared beamline is hundreds of times as intense as conventional infrared sources and can be focused to a spot less than 10 micrometers in diameter, smaller than the dimensions of a typical mammalian cell.
"We can position the spot on a sample within one micrometer," says Wayne McKinney, who developed the beam line with Martin. He adds that "because the synchrotron light comes in pulses two nanoseconds apart, we can record very fast changes in cells." Although this capacity has not been applied to work done so far, it promises to open new insights into cellular processes.
So far, Holman and her collaborators have concentrated on the response of cultured human cells to low doses of environmental agents. In lung cells, they have shown that different oxidizers and x-rays produce different kinds of damage marked by distinct spectral changes. In liver cells, their work indicates that dioxin's influence is related to its interaction with a specific binding site.
They have also recorded distinctive spectra from lung cells going through different stages of the cell cycle. With other researchers, they plan to study radiation and drug therapies for brain tumors and oxidative stress in such diseases as atherosclerosis, diabetes, and rheumatoid arthritis.
SR-FTIR spectromicroscopy allows studies of live cells impossible or impractical by any other method, enabling basic studies of the life, death, damage, and self-repair of tissues and cells at the subcellular level.

When the Department of Energy's "Tiger Team" safety inspectors came calling in the early `90s , Moré was named Budget Manager for Environment, Health and Safety, which subsequently grew from 50 employees to about 150.
In 1995, Moré was asked to coordinate the logistics of the move of the National Energy Research Scientific Computing Center (NERSC) from Livermore to Berkeley Lab. He set up the office budget system and staff to manage the $100 million operation.
And when the Laboratory's institutional budget manager departed in 1997, Moré stepped in and took on responsibilities that included oversight of the laboratory's $346 million budget.
"I like to fix problems, to bring people together and make things work," he says. "I'm not a strong maintenance person."
About seven years ago, Moré began working with then-Manager for Administration Cheryl McFate on implementation of a concept that would maximize administrative support services and share resources within a constrained financial environment within Operations. This evolved, in 1996, into a Laboratory-wide organization called the Administrative Services Department (ASD), whose ambitious goal was to provide seamless services across organizational lines, end duplicative systems, and build uniform standards and expectations in areas such as office management and support, finance, human resources, procurement and inventory, and work support.
Now, after three years of promising development -- and the inevitable growing pains -- ASD enters the new century with a new vision and an invigorated future. And Berkeley Lab has turned to its ultimate "firefighter," Moré, to stabilize and steer it as Department Head.
Sitting in his new office in the downtown business center at Building 937, Moré reflects upon the accomplishments to date in ASD and the challenges this 375-employee unit faces in its next phase of development.
"We achieved some great things in our first years," he said, crediting ASD's inaugural manager, Meredith Montgomery. He noted the development of management clusters serving related research areas, improved performance review and salary-setting procedures, standardized administrative procedures lab-wide, an effective "flywheel" concept for short-term service needs, and improved career development opportunities for ASD staff.
On his whiteboard, Moré points to the lingering issues that he's been asked to address. At the top is "administrative assistant," employees who constitute three-fourths of the ASD workforce. With a 14 percent vacancy rate at present, recruitment in a competitive market is a top priority.
"Training is another issue," he said. "Some get it, some don't. We have, or will be getting, new (data) systems, and we need to train people on how to use them at the desktop."
He talks hopefully about integration -- bringing human resources and financial services together -- and enhanced communication at all levels. Moré's first "Level One" communique to ASD personnel in his new role announced his intention to strengthen intra-departmental ties through open communications, frequent updates, and periodic "town hall" and group meetings to broaden dialogue.
"We're here for the scientists," Moré says of the underlying mission of ASD. "How can we best provide administrative services to match the world-class science here? Scientists shouldn't have to worry about how it's done; they needn't care. The product will just be delivered, efficiently and economically."
In three years, he says, he'd like to see "a much more focused, integrated, seamless organization."
And Moré knows how it's done. He was the central player in another successful model -- the General Sciences and Directorate administrative team in Building 50. In two years as business manager there, he directed an administrative staff of 70 across major functional areas, setting up "centers" for human resources, budget and business processes. Division Directors were co-located in one suite to facilitate resource sharing and realize economies of scale. The transformation has received high marks from General Sciences Division directors.
Moré is the right man for the top ASD job primarily because of where he's been at the lab. He talks about the different perspectives that "central" and "field" experiences bring. Whereas central administration responds to the demands of the DOE and broad lab management, employees in department and programs ("the field") have more immediate concerns about local service delivery.
Moré has been in both, experiences which he says have been invaluable for him in assessing the needs of the department. One of the tensions inherent in the organization -- a perception that the central ASD office is the "police" -- should go away with Moré's administration. He has a lean and efficient four administrators working for him downtown, and he says, "Decisions should be made in the field. We (central) will only be involved if we can add value. It all has to be customer-focused."
Now he's hard at work on a shared vision for ASD, which he hopes to deliver to management later this spring. And that's a long way from tagging property, which was his first job at Berkeley Lab as a summer student in 1981. He was in business school at Menlo College at the time, and thanks to his father's successes in the facilities department here, Anil decided to check out the place on his own. He never left, working right through an MBA in finance, with the Lab's assistance, from Golden Gate University in 1983.
Vish Moré, his dad, is notable as the project manager for two of Berkeley Lab's prize buildings -- Building 2 and Building 66. He retired a few years ago after 15 years at Berkeley and 25 years at DOE facilities, including Abbott Lab in Illinois, Livermore and the Stanford Linear Accelerator Center.
"I like to think I'm carrying on the family name," Moré says proudly.

Human resources and benefits representatives will be available to talk about career and job opportunities at the Lab. Information about student assistant positions, internships, fellowships, and educational resources will also be available.
Lab Artist Designs New Pac Bell Stadium Cup
Although designed initially for the insulating layer on the cups, the stadium coffee vendor liked the picture so much that it is also being used for banners on coffee carts. Bailey got the job through her ties to Juma Ventures, a San Francisco firm which works with businesses to provide business experience for inner-city youngsters. Her artwork features some of those kids in all their diversity as they work as vendors for the coffee concessionaire at the ballpark. More of Bailey's artwork, also part of her work with Juma, also graces the Ben and Jerry's ice cream carts at Pac Bell Park and Candlestick Park, which the Giants called home until this season.
Trained as an advertising illustrator, Bailey was hired by the Lab as a geological illustrator in 1979. Since then, her talents have graced everything from the Runaround T-shirts to the historical display in the Bldg. 50 lobby. She's currently doing the graphic presentations for the upcoming Lab Open House on Saturday, May 6. For her extra-innings artistic efforts with the Giants, Bailey earned both a commission and four coveted tickets to one of the sold-out games in the intimate new park overlooking San Francisco Bay.
"My mom and I are big baseball fans, and anxious to see the new park," Bailey says, "so you bet we'll be there on April 15."

VOICE MAIL: Date and Time-Stamp Feature Change
Great news! Telephone Services has announced a change in the date and time-stamp feature on lab telephones. Previously, this feature was only accessible by pressing "8" (or "t" for time) while listening to your messages. You may now choose whether you hear the date and time-stamp automatically, or only when the digit "8" is pressed.
If you would like to choose the option of hearing the date and time-stamp automatically, send e-mail to email@example.com or call x7997. Be sure to include your name and extension. There is no charge for this service.
