When Berkeley Lab Director Charles Shank arrived here 10 years ago, the
facility had an operating budget under $200 million, the General Sciences
(including the Bevatron) represented more than a third of the research, and
computing sciences barely made it on the programmatic pie chart.
Today, operating budgets run around $323 million, the Biosciences and Energy
Sciences make up the biggest slices of the pie, and computing sciences, with
the recent arrival of the supercomputing center, represent almost one-fifth of
"It's been pretty much continuous growth," Shank told a capacity audience in
the Bldg. 50 auditorium on June 30 at his annual State of the Laboratory
address. But rather than look back, he said he'd prefer to look ahead to the
Lab's prospects and opportunities for the next 10 years.
His "Vision 2010," with its five prospective growth areas, holds enormous
potential for new activities, Shank said. The unique capabilities and
competencies of the Laboratory, tied together by computing and computation and
multidisciplinary teams working at the edges of their fields, "give the Lab an
extraordinary vitality and a real opportunity to make significant advances in
the years to come," Shank said.
Those areas include work in the fundamental understanding of the universe,
complexity and complex systems, quantitative biology, new energy sources and
environmental solutions, and integrated computing, the enabling tool of the
21st century, he said.
Summarizing this year's milestone research breakthroughs in astrophysics and
nuclear science -- discovery of the "accelerating universe" and of two new
heavy elements in the periodic table (118 and 116) -- Shank took note of
Berkeley Lab's recognized leadership in studying the fundamental properties of
"We have an opportunity to take what's out there (in space) and use it to apply
to a new understanding of the universe and particle physics," he said. The
director outlined a new research initiative being driven by astrophysicist Saul
Perlmutter to mount a 1.8-meter telescope on a satellite to further probe the
properties of the universe by studying distant supernovas. He said a
partnership with NASA is possible.
Shank also cited the recent contributions made by Berkeley Lab to major
national scientific facilities studying the fundamental properties of matter:
the STAR detector at Brookhaven's Relativistic Heavy Ion Collider, the Sudbury
Neutrino Observatory in Canada, and the B Factory at the Stanford Linear
Accelerator Center -- all on-line or scheduled to take data this summer.
He noted that future projects speak to the need to develop new, more
cost-effective ways to study basic questions in particle physics "on the edge
of the energy frontier." One such tool could be optical and laser accelerators,
combined with the analytical capabilities of large-scale computing.
In all of these cases, Shank told Lab employees, project successes derived
significantly from the important contributions of the Engineering Division and
cited the newest division director, Jim Triplett, for the valuable perspectives
he will be bringing to the engineering program.
The research field known as "complexity" was explored recently in a workshop
hosted by Berkeley Lab and co-chaired by DOE's associate director for Basic
Energy Sciences, Pat Dehmer. Shank said this is a fertile ground for scientific
exploration, in areas such as understanding molecular machines and new
materials design and assembly.
He said the Advanced Light Source will be a significant contributor to such
efforts in the coming years. The ALS, which he described as being "on a very
positive slope," increased its user base three-fold in only two years. "It's
becoming a hotbed of scientific activity," he said, citing recent advances in
the areas of superconducting quasiparticles, nanostructure imaging,
photoemission electron microscopy, and macromolecular crystallography. Third
harmonic cavities are installed and working to increase the beam lifetime, and
forthcoming superbend magnets will increase brightness in the intermediate
x-ray regime of the ALS, he added.

In quantitative biology, Shank called out the work of the Joint Genome
Institute and its massive collection of data as central to the challenges ahead
in what he called "a revolution in biology."
"Biology has been an observational field," he said. "But now it's moving into a
more quantitative field, and in the new century it will be a predictive
science. Physics, chemistry and math will play more important roles as we build
on the work in the genome, through modeling and simulating systems through
New technologies are being deployed at the Lab to study structural dynamics and
the complexities of so-called molecular machines, he said, with Berkeley Lab
nicely positioned to lead the effort. He pointed to a new partnership with UC
Berkeley in the biosciences as a key component "which will synthesize the
strengths of both institutions."
As the world addresses problems growing from today's fossil-fuel-based economy,
work in energy and environment will become increasingly important. Shank
pointed out Laboratory initiatives in inertial fusion energy, carbon
sequestration, and electricity reliability as prime target areas for
He also recognized two efforts in energy efficiency this year that brought
praise to Berkeley Lab: the national launch of the interactive Home Energy
Saver website and the integrated lighting project at the Rodeo Post Office,
which will be adapted to a national program by the U.S. Postal Service.
Shank took the time to cite three individuals who received prestigious honors
in their fields: John Clarke, who earned the National Academy of Sciences'
Comstock Prize for his work with Superconducting Quantum Interference Devices
(SQUIDS); Andrew Canning, whose team received the Gordon Bell Prize for highest
computing speed using a real-world application; and Phil Colella, who won the
Sidney Fernbach Award for major contributions in software methodology
"The world of computing is changing very rapidly," he said. "The sophistication
here has increased dramatically since the arrival of NERSC, but still we have a
ways to go to make computers an essential tool for discovery."
Shank pointed to the recent arrival of the new IBM "NERSC 3" computer which,
when completely installed, will boost the total NERSC supercomputing capacity
to four teraflops. He noted that the machine will eventually be named
"Seaborg," in honor of Berkeley Lab's distinguished Nobel laureate who died in
Shank closed with a personal reflection about the recent Department of Energy
difficulties over issues surrounding secrecy and security at the national
weapons laboratories. Saying that Berkeley Lab, which engages only in
non-classified research, "has been built on a foundation of international
connections and by people from all over the world," he vowed to "vigorously
pursue opportunities to create an environment in which the entire world is
welcomed here and that encourages the interchange of ideas."
In answer to a follow-up question, Shank added, "I believe in the process of
working out something [in Washington] that will keep our laboratory the way it

The intricate and mysterious architecture of the cellular microcosm -- complete
with its own "freeways," "comets," and a host of other until-recently-invisible
structures -- came to life with stunning visual clarity last Wednesday during
Berkeley Lab's first summer lecture of the season. The speaker -- cell imaging
expert Carolyn Larabell of Life Sciences -- could not have asked for a better
audience, which nearly filled the Bldg. 50 auditorium. Nor could her audience
have asked for a more timely, cutting-edge topic to kick off the five-week
lecture series -- or a more respected expert in the field.
Entitled "Imaging the Cellular Universe: Comets, Particles and Transport
Phenomena," the lecture zeroed in on the rapid advances in the field of cell
biology, which were made possible by powerful new imaging tools that allow
scientists to peer inside whole living cells.
"It's a very exciting time in developmental biology," said Larabell, a pioneer
in the application of x-ray microscopy to this field, as she unveiled
spectacular images and time-lapse films, whose impact was further enhanced by
state-of-the-art presentation tools.
"Cells are very dynamic," she said. "While you're here relaxing they're very
busy, doing a lot of things."
Larabell has devoted much of her career to studying and imaging the innermost
secrets of the cells: their structure, how they function (or misfunction), why
abnormalities such as cancer occur, how disease penetrates cells, and the
mechanisms by which particles of many different sizes use to move in and out of
To understand these phenomena, cell biologists today, in what Larabell called
the post-genomic era, need new and increasingly more powerful imaging
techniques, not necessarily to replace but to complement the time-tried ones.
Over the decades, scientists have relied on three types of technologies to view
cell structures: The oldest, most commonly used method is light microscopy.
Unfortunately, its best resolution (200 nanometers) is not adequate for many of
Electron microscopy, Larabell said, revolutionized our understanding of cells
during the 1960s and 1970s. With its extremely high resolution (a tenth of a
nanometer or better) it unveiled for the first time the very organized
structure of the cells. "They have an architecture," she said. "Like buildings
have foundations, so do cells." The downside of the technique is that cell
slices must be dehydrated and embedded in plastic to be viewed, a process which
can result in loss of protein, which is precisely what scientists like Larabell
want to study.
This is where x-ray microscopy comes in. The technique, used at beamline XM-1
at the Lab's Advanced Light Source, provides high resolution information in
thick, hydrated cells.
To illustrate the power of these tools Larabell displayed pictures of
fertilized frog eggs injected with fluorescent proteins. As the labeled
proteins penetrate the membrane, they permit the imaging of a cascade of
biochemical events. The film, sped up 30 times, vividly showed that chain of
As a means of comparison, Larabell also projected an image of a membrane
obtained with an electron microscope. The remarkably detailed picture showed
even more of the cell's structure, but was static. Therefore, Larabell
explained, scientists need a variety of imaging techniques to obtain both
spatial and temporal information.
Larabell's films showed some very busy particles which she calls "comets,"
complete with tails they build from actin molecules to move inside the cell and
push around subcellular particles. Unfortunately, these same actin comets also
act as vehicles to drive particles into dangerous -- sometime fatal --
encounters with bacteria, such as Listeria, which infects meat.
"The bacteria are very clever and have created a mechanism to move around
cells," Larabell said. "It turned out to be a very handy mechanism: 20 percent
of the people who became infected died."
As it turns out, she added, the bacteria did not create this mechanism but
penetrated the cells and then used the cell's existing mechanism.
To understand this system Larabell uses the x-ray microscopes at the ALS. At a
resolution of 30 to 50 nanometers, her images have recently revealed
never-before-seen linear structures inside cells which act as a transport
"It's pretty much like a freeway system in the Bay Area," she said pointing at
the screen, and quipped, "actually it's much faster than a freeway system in
Bay Area" -- at a whopping 30 microns a minute. Another film of particles
moving at nearly 50 microns a minute she likened to the "hustling and bustling
in downtown New York at Christmas time."
Fun aside, Larabell is constantly keeping busy delving deeper and deeper inside
the cells to answer some key questions about them. One of her foremost goals is
to understand the cell nucleus. Only a few decades ago, she said, did
scientists begin to realize that cells are not cushy bags filled with jello but
highly organized structures. Today we are on the verge of understanding the
nucleus and unraveling its organization.
Larabell and her colleagues also hope to improve scientists' understanding of
the "scaffolding" supporting the cells, which they hope will lead to advances
in the area of breast cancer.
As better techniques for cell imaging are developed, a new universe opens to
science, and Berkeley Lab and researchers like Larabell are key players in this
new era of cell biology.
"We are very fortunate here at Berkeley Lab," Larabell says, "because we are in
a position to pioneer a technique for imaging cells which is used by cell
biologists around the world."
The next summer lecture, on July 21, will feature Pier Oddone who will talk
about "The Asymmetric B Factory: Reflecting the World in the CP Mirror."

It's the dead of winter at the South Pole's Amundsen-Scott Station: 41 people
inside the dome, and outside, round-the-clock darkness, 60 mile-per-hour
blizzards, temperatures at 80F below -- and it's over 800 miles to the nearest
human settlement. Nobody gets in or out until spring, October at the earliest.
On June 28, after a 47-year-old American woman who works at the station
discovered a lump in her breast, a call for help went out by e-mail. Medicine
and diagnostic tools were urgently needed. An emergency airlift was the only
Chuck McParland of Berkeley Lab's Information and Computer Sciences Division
got the call from the National Science Foundation, which runs the polar
station. He immediately volunteered the Lab's assistance. Computer
communications software and hardware were critical so that personnel at the
South Pole could confer in real-time with doctors in the United States and
exchange medical images.

consultant to the Comprehensive Test Ban Treaty Organization, contributed her
expertise; Agarwal's use of Multicast Backbone tools (MBone) for NASA's "Live
From the Poles" educational TV program in 1998 had alerted the NSF to Berkeley
Lab's Internet conferencing capabilities.
McParland took the lead, and within days Lab personnel had assembled the
communications package. "We specified the right equipment for reestablishing
the link and helped track down the necessary equipment," he says; the equipment
includes two noise-cancelling headsets donated by the Lab. Inquiries to
Department of Energy colleagues at Argonne and Oak Ridge National Labs helped
locate the digitizing cameras for use with microscopes. McParland also helped
find vendors who had the equipment in stock and who could deliver overnight.
"It was amazing -- everyone just jumped in with both feet," McParland says,
crediting researchers from NASA, the NSF and other organizations. "There was a
real sense of `Do it now! Do it fast!'"
A Lockheed C-141 Starlifter from McChord Air Force Base in Washington State
flew the equipment and supplies to Antarctica via New Zealand. From
Christchurch to the South Pole is a 6,375-mile round trip, with the pole itself
at 10,000 feet altitude. The big jet made two passes over the station on
Sunday, July 10, dropping six pallets 700 feet to a target area marked out by
blazing oil drums.
The Lab's part of the package included two computer workstations and
microscopes equipped with digital imaging cameras -- duplicates against mishaps
when the pallets hit the ice at 60 mph. Guided by flashing strobes on the
pallets, ground personnel had just seven minutes to bring the gear in out of
the howling, subfreezing darkness. An apparently successful drop was confirmed
by Air Force personnel and reported by the Associated Press earlier this

changes mind on ANS
In a reversal from an earlier position, Energy Secretary Bill Richardson has
now endorsed a proposal by Senate Republicans to create a semi-autonomous
Agency for Nuclear Stewardship (ANS) within DOE.
With the senators apparently having satisfied Richardson that his authority
over the weapons complex would not be diminished, the Secretary's staff members
are telling reporters that they have been directed "to accept the notion of a
semiautonomous agency and to negotiate with Congress."
Leading the negotiations for DOE will be J. Gary Falle, Richardson's chief of
staff; R.P. Eddy, a special assistant; Joan Rohlfing, senior policy adviser for
nonproliferation and national security; and John Angell, assistant secretary
for congressional intergovernmental affairs.
The ANS proposal was crafted by Republican Senators Pete Domenici of New
Mexico, Frank Murkowski of Alaska and Jon Kyl of Arizona, based on
recommendations from the President's Foreign Intelligence Advisory Board.
Similar legislation has been introduced in the House. -- Lynn Yarris

Microscopist Werner Meyer-Ilse, one of the brightest lights in the galaxy of
star researchers at Berkeley Lab's Advanced Light Source, died on Wednesday,
July 14, from injuries sustained in an automobile accident in Germany. He was
Meyer-Ilse was a staff scientist for the Center for X-ray Optics (CXRO) in the
Materials Sciences Division, and the man who directed the design and
construction of ALS beamline 6.1.2. Also known as XM-1, this beamline is a
direct-imaging transmission x-ray microscope acknowledged by experts to be one
of the finest instruments of its kind in the world. Once it was built,
Meyer-Ilse oversaw all the research conducted with it.
"My personal interest is to develop x-ray microscopy, and I am only able to do
this in a collaborative manner," he once said in an interview. "Therefore all
of the users of this beamline, from all their different scientific fields,
become my collaborators in developing the technology."
Meyer-Ilse is survived by his wife, Andrea, and his daughters Eva, a freshman
at U.C. Berkeley, and Julia, a high school student. The family resides in
At the time of the accident that led to his death, Meyer-Ilse was in his native
Germany to deliver a talk on x-ray microscopy. The talk was in Hamburg, and on
the train ride back to the airport in Frankfurt, Meyer-Ilse stopped in his home
town of Göttingen to visit family members. He was born there on Aug. 18,
1954, grew up on a farm that had no electricity, and attended the famous
University of Göttingen's Third Physical Institute
His wife Andrea is also from Göttingen, and they were high school
Meyer-Ilse first came to Berkeley Lab in 1989 to work as a physicist with the
Accelerator and Fusion Research Division. He was here only a few months before
going back to Germany. He returned on a more permanent basis in February 1992
to work at the CXRO on the development of XM-1 and future high-resolution x-ray
"Werner thought of the Lab as a very special place, and he was here to stay,"
said CXRO head David Attwood. "He wanted to do every aspect of the microscope
and every application. It was, he said, the only way to ensure excellence."
Meyer-Ilse will be buried in Germany. A local memorial service will be arranged
after his wife's return.

Two technologies developed by researchers in Berkeley Lab's Environmental
Energy Technologies Division (EETD) made the list of five energy-saving
initiatives sponsored by DOE in the 1990s that were singled out by the American
Council for an Energy-Efficient Economy (ACEEE) as the decade's "most
successful." They are the compact fluorescent lamp (CFL)-based replacements for
halogen torchieres, a development led by Michael Siminovitch, and spectrally
selective low-emittance (low-E) and solar control windows, a development led by
Michael Rubin. Both researchers work in EETD's Buildings Technologies
The other three initiatives were new housing designs and construction
techniques from the Building America program, alternative refrigerants and
insulation blowing agents, and building standards and guidelines. All five
technologies were funded under DOE's Office of Buildings Technologies.
"These [five technologies] demonstrate that DOE can achieve a high degree of
leveraging and impressive results with modest R&D, testing, or deployment
support," said Howard Geller, ACEEE's executive director, who presented a
report to Congress this past spring on his organization's study of the five
ACEEE is a nonprofit organization dedicated to advancing energy efficiency as a
means of promoting both economic prosperity and environmental protection.
"Some of the projects, such as the CFL torchiere and solar control windows,
cost the federal government less than $5 million each," said Geller. "But by
addressing clear needs in the marketplace and fostering partnerships between
DOE's national labs and the private sector, these projects were very
CFL torchieres use about one quarter of the energy and put out more light than
halogen torchieres -- plus they are much safer because they operate at far
cooler temperatures. In 1997 the CFL torchiere won the "Best of What's New"
Grand Prize Award for Home Technology from Popular Science magazine. Working
with Siminovitch on its development were Erik Page, Jeffrey Mitchell and Linsey
Low-emittance coatings have a high reflectance of infrared light, which enables
them to admit as much daylight as possible while reducing solar heat gains and
losses. Rubin carried out assessments for DOE which showed that cooling costs
due to windows are significant even in colder climates and that reducing solar
gain in hotter climates can substantially cut energy costs. He also
demonstrated that a significant degree of solar control can be built into these
coatings through select spectral reflectance.
Stated the ACEEE study report, "These (Berkeley Lab) studies helped convince
major glass and window manufacturers to introduce solar control low-E glazings
in the late 1980s and early 1990s."
ACEEE concluded in its study that the benefits from these program have far
exceeded costs, and called upon DOE to expand and replicate them.

In May, in a two-to-one split decision, the U.S. Circuit Court of Appeals for
the District of Columbia declared parts of the Clean Air Act unconstitutional.
The decision threatens implementation of the Environmental Protection Agency's
1997 air quality standards, which are based on health effects and include
standards for particles only 2.5 micrometers in size. Yet the court also stated
that "evidence demonstrating a relationship between fine particle pollution and
adverse health effects amply justifies establishment of new fine particle
Thus it seems unlikely that national standards for fine particulate matter will
be delayed for long. In June, EPA Administrator Carol Browner testified before
Congress: "We stand by these standards. We stand by the science. We stand by
At Berkeley Lab, Lara Gundel of the Environmental Energy Technologies Division
(EETD) emphasizes that "there are lots of unanswered questions about how
particulate matter affects health," and she is busy developing and implementing
a means to help answer some of these questions.
"Particle size is one factor," she says, "but particles are of very different
kinds -- acid droplets, metals from incinerators, toxic compounds from gasoline
and diesel fuels, soot from unburned fuel, and many others."
Moreover, many pollutants exist in both particle and gas phases, including
polycyclic aromatic hydrocarbons, which are ubiquitous in urban areas because
of sources such as vehicle exhaust, and pesticides which abound in agricultural
"A major scientific problem has been getting good measurements of the
partitioning of these chemicals between the gas phase and airborne particulate
matter. At Berkeley Lab, we have the tools to answer these questions." These
tools include some of the most advanced and versatile in the field, which is
one reason why the EPA has kept Gundel busy as an expert on sampling.
The tools are available because 10 years ago Gundel, her colleague Joan Daisey,
head of EETD's Indoor Environment Program, and their associates began
addressing similar problems in studies of indoor air quality. "We had a special
interest in the physical and chemical characteristics of second-hand tobacco
smoke," she says. "Tobacco smoke is an aerosol that dries fast. We realized we
didn't know much about its gas-particle partitioning, and we needed a way to
Gas and particles are deposited differently in the lungs and have different
physiological effects. According to Gundel, the partitioning, over time, of the
phases of a semivolatile organic substance such as nicotine "has thrown a
monkey wrench into many measurements" aimed at determining health effects.
Most phase measurements have been made by trapping solid particles on a filter
and then collecting gases from underlying adsorbent beds. The filter itself,
however, can absorb gases, and the particles may give up gases after they are
trapped; both vaporization and condensation effects can thus lead to errors.
That's why Daisey suggested that Gundel and her colleagues in the tobacco study
use a "denuder" -- a device that traps gas and allows particles to be collected
separately. Denuders are not commonly used with organic chemicals but, Gundel
says, "as soon as Joan mentioned a diffusion denuder, I said, `I know how to do
that,' and I vizualized the solution. It was a leap of faith."
Her idea was to use sticky resin beads whose pores were the right size to trap
molecules of organic gases -- small enough to adhere through friction alone to
the sand-blasted inner surface of a glass tube.
"Solid particles are relatively massive and travel straight through the
denuder," Gundel explains. "The gas molecules are moving all over the place,
like toddlers; eventually they hit the wall and stick. The trick is to
calculate the airflow and the length of the tube -- to make it short enough so
the particles stay airborne but long enough for the gas to get trapped."
After an air sample is sucked through the denuder, the particle filter is
removed and the gas trapped on the resin beads is analyzed.
Gundel had a working model of a denuder which she later named the Integrated
Organic Vapor/Particle Sampler, or IOVPS, built for the tobacco-smoke study.
"We tried it in a room-sized chamber that held smoke from a single cigarette.
In about 30 seconds we knew it was going to work."
Gundel refined the IOVPS as part of a successful Cooperative Research and
Development Agreement with URG Corporation in North Carolina, increasing the
denuding surface and designing new features for collecting vapor subsequently
released from trapped particles. A few years ago a Canadian researcher, Douglas
Lane of the Atmospheric Environment Service, collaborated with Gundel to modify
the IOVPS for much higher flow rates and continuous operation -- up to 48 hours
at time -- which would allow it to be used for testing the atmosphere outdoors.
The resulting Integrated Organic Gas and Particle Sampler (IOGAPS) comes in
several sizes, the largest of which uses two denuder tubes with about 30 times
the coated area of a single-channel IOVPS.
Groups around the country have employed this sampling technology in studies of
semivolatile organic compounds. Among these have been investigations of the
atmospheric behavior of dioxins and the contribution of diesel, other vehicle
exhausts, and wood smoke to smog formation -- all under different weather
conditions, in different parts of the country, and at different times of the
day or night.
The EPA recently tested various air-sampler designs in cities throughout the
country. As a kind of control for this test, the denuders were installed on
what Gundel calls "old pieces of sampling equipment taken out of mothballs. The
denuders are fitted on them like nozzles on vacuum cleaners." Air samplers with
denuders got better results than samplers without, and now the IOGAPS devices
are being used in other field studies in Seattle, Nashville and Atlanta.
Gundel has also been testing "vacuums" with denuder "nozzles" for other
interesting applications, such as cleaning the air in buildings. And to serve a
wider range of uses, Gundel and her associates are evaluating various denuder
designs -- some durable and pricey, others lightweight and based on common
products available in hardware stores. A patent for the IOVPS technology was
awarded in 1998, and Gundel and her associates are actively seeking licensing
partners through the Lab's Technology Transfer Department.
Already researchers armed with Lara Gundel's resin-coated denuders are finding
out exactly what's in the air -- and in what phase -- all over the nation.

For the second consecutive summer, 30 science teachers from the Vallejo Unified
School District and surrounding area have joined Berkeley Lab in a four-week
educational project that aims to strengthen the district's science program
through curriculum development workshops and joint science research between
teachers and scientists.
"Not everyone lives down the road form a national laboratory," says James
McLelland, a physics teacher at Dr. James J. Hogan High School in Vallejo.
"It's the deal of a lifetime."
The Integrated Science Partnership Project (ISPP) -- codirected by Marva
Wilkins, the Lab's education outreach coordinator, and former Berkeley High
School science teacher Don Hubbard -- is funded by a federal grant to build a
nontraditional integrated science curriculum in Vallejo area high schools.
The project is divided into two working groups: curriculum developers, in which
teachers team up to develop new classroom agendas, and "teachers as
investigators," who conduct actual experiments alongside volunteer Lab
"The ALS is a live example of integrated science," says Hubbard. "In this
multidiscipline science research facility teachers can see a true
representation of real life science. They get a more realistic sense of who
scientists are and what science is than is possible in the classroom."
The project was conceived by Marva Wilkins of the Center for Science and
Engineering Education. "The need for innovative, quality staff development
programs for teachers was the motivation for ISPP," she says. "The support of
staff labwide, along with the rich resources here, make it possible to provide
educators with this unique experience. Observing the teachers' enthusiasm and
high energy makes this project one of the highlights of my career in
Teachers in the program expand the traditional scope of a science class to
include lessons on ethics, history, and social and cultural aspects of science.
Says Susann Evans, coordinator for the curriculum development group and a
teacher at Jesse Bethel High School, "Ultimately we want the students to become
stewards for their environment -- to look at its value and protect it."
Through ISPP teachers are developing innovative and engaging ways to stimulate
their students. As a result of last year's program, for example, Vallejo High
developed a "murder mystery" unit for their tenth grade integrated science
class. Tom Knight, a Vallejo High science teacher, thought of the idea with Lab
scientist Mike Martin, who uses infrared spectroscopy for forensics. The
detective work of the students at Vallejo High included learning about DNA and
analyzing footprints using chemistry, biology, physics, and math. This spring,
students' science scores on the SAT9 statewide achievement test at Vallejo High
were higher than those of the previous year, a trend the teachers hope will
continue as the program develops.
"When teachers are reenergized, they bring that energy to the classroom," says
Cliff Solari, the assistant superintendent of the Vallejo School District, who
came to observe his teachers at work. "The kids get excited about science and
Tony Farley, the research coordinator for ISPP and a teacher at San Leandro
High School, says his experience with ISPP last year prompted him to enhance
his curriculum to include the Big Bang and particle physics. "We couldn't do
this work without the Lab," he says. "It's amazing how generous the scientists
have been with their time and explanations, and how excited and supportive they
are. Getting to work in this environment is inspiring."
Teacher research activities include Mike Martin and Wayne McKinney's project to
measure pesticide runoff and other pollutants in a Vallejo creek; Eddie Moler's

"Projects like our creek water analysis demonstrate to students that science is
a lot of problem solving," Martin says. "This will hopefully help inspire them
to look at other interesting questions all around them. By showing these
students some of what is done at the Lab we are making science come alive --
and making that place up on the hill a lot less of a mystery."
The Berkeley Lab fire department was the first to arrive on the scene to put
out a wildfire in Strawberry Canyon on the evening of July 9.
"Our firefighters were able to get on top of it in a hurry, and catch it on the
run," said Lab fire chief Stacy Cox.
On June 17, Laboratory Director Charles Shank and City Manager James Keene
signed a memorandum saying that the Lab fire department would provide
first-response service in specified zones where the Lab could arrive fastest.
This fire occurred within one of the agreed upon "first-in" zones, and its
rapid containment was a successful example of the collaboration among the
various fire departments, Cox says.
When a column of smoke was spotted through a window facing the canyon at 8:00
p.m. last Friday, acting captain David Piepho, driver Charles Palmer and
firefighter David Cesmat responded immediately. As a result, the fire was
rapidly contained. About one quarter of an acre of brush and trees were burned,
but no buildings were in immediate danger.
The Berkeley Fire Department was notified on dispatch of the Lab crew, and
arrived to find the fire extinguished.
Oakland also responded, standing by at the Lab in case further assistance was
needed.-- Blake Likins

Former SLAC Director Addresses National Security Issues
"Don't overestimate conspiracy and don't underestimate incompetence," warned
Wolfgang K. H. Panofsky, director emeritus of SLAC during a noon lecture on
Addressing a packed Bldg. 50 auditorium, the famous physicist discussed the
Chinese espionage scandal and accused the congressional report on Chinese
intelligence activities, which was chaired by Rep. Christopher Cox (R-CA), of
"casting aspersions it could not support."
Panofsky also criticized the media for hyping the report's allegations of
security breaches while largely ignoring the far less sensational conclusions
of the U.S. intelligence community. Photo by Roy Kaltschmidt.

Safety Tips for Bikers And Pedestrians
Now that summer is here, more people are enjoying the nice weather by walking
or bicycling on the Hill. To prevent any undesirable close encounters with
vehicles, EH&S offers some basic safety tips for pedestrians and
- Whenever possible, walk on sidewalks.
- When sidewalks are not available, walk on the side of the street facing
- Do not take shorcuts through unpaved surfaces, as uneven, broken ground
increases the possibility of falls and other mishaps.
- Bike defensively -- that is, expect the unexpected from cars and other
- Do not pass cars when traveling downhill.
- Use brakes just as cars do.
- Remember that drivers may not see a bicyclist in time when pulling into
traffic from driveways.
A little safety awareness can go a long way towards getting all of us home in
one piece every day.
Surplus Office Supplies
The Bldg. 903 warehouse has surplus office supplies available to any Lab
employees. Included are items such as three-ring binders in a variety of sizes,
as well as more costly office supplies. For more information call Charles at
Mountain Lion Sighting
A mountain lion was spotted on the Hill last weekend crossing Centennial Drive
from the Lab to Strawberry Canyon, just below the Botanical Garden.
Although as a rule mountain lions are wary of people and try to avoid us, safe
is safe; so we may want to do our share to stay out of their way and, most
importantly, come away unscathed should we encounter our feline neighbors.
Some helpful tips on the subject, prepared by the California Department of Fish
and Game, can be found on the UC Police Department website at
http://www.berkeley.edu/ucpolice, under the heading "crime alerts."
Basic safety tips include: do not run from the lion but stand and face the
animal; do not turn your back or make any sudden movement; make eye contact;
avoid squatting, crouching or bending; do all you can to appear larger; and
fight back if attacked.
For further information contact Treacy Malloy of UC's Office of Emergency
Preparedness at 642-9036.

Lab Tour of the Treasury of St. Francis of Assisi
The Employees' Art Council has arranged a docent tour of the Treasury of St.
Francis of Assisi exhibit being held at the California Palace of the Legion of
Honor in Lincoln Park. The Lab tour will take place on Saturday, Aug. 28,
beginning at 9:00 a.m. -- half an hour before the museum opens to the public.
The Basilica of San Francesco in Assisi, Italy, is the repository of some of
the most important masterpieces of medieval and early Renaissance painting,
sculpture, metalwork, textiles, and manuscript illumination. These rare works
of art, many of which date from the 13th and 14th centuries, will come to
Assisi's sister city San Francisco in this once-in-a-lifetime exhibition that
celebrates the treasures of Saint Francis and raises public awareness about the
severe 1997 earthquake damage to the famous basilica.
Additional information on this exhibition can be found on the web at
The full text and photographs of each edition of Currents are published online
at http://www.lbl.gov/Publications/Currents/. You may find a link to Currents
on the Lab's home page under the heading "Publications." The site allows users
to do searches of past articles going back to 1994.
The Berkeley Lab Calendar is published biweekly here on the World Wide Web and in Currents
by the Public Information Department. Employees can list a meeting, class, or event in the
Calendar by using this submission form.
The deadline for submissions is 5 p.m. on Monday in the week that Currents is published.

Is the Earth's Climate Quantized? Evidence for Abrupt Switching Between
Cold and Warm Phases from Gases Trapped in Polar Ice Cores
Presentation by Jeff Severinghaus of UC San Diego
The B Factory
Lab Deputy Director Pier Oddone, recognized as "the father of the B
Factory," will talk about this five-year, $287 million project during a lecture
on "The Asymmetric B Factory: Reflecting the World in the CP Mirror." The
accelerator's collisions of electrons and positrons are intended to produce
particles of matter and antimatter whose study may offer clues to the standard
model theory of how the universe developed.
Supernovae and the Expanding Universe
Particle physicist Gerson Goldhaber of the Supernova Cosmology Project
will present "direct evidence for the expansion of the universe" in his talk on
"Supernovae and the Expanding Universe" -- a discovery Science magazine named
the "Breakthrough of the Year" in December. What drives the accelerated
expansion may well be a version of Einstein's cosmological constant, "something
particle physicists hate, but cosmologists are learning they can't live
without," says Goldhaber.
AIM, a Walnut Creek-based computer software training firm, provides onsite PC
computer courses to Lab employees.
Classes are held in Bldg. 51L. For more information on AIM training, class
description and registration procedure, look up the class website at
