Anyone reading the credits of PBS science specials
this year might get the impression that the network turns to Berkeley
Lab whenever it needs a star. Half a dozen researchers from the Life
Sciences, Earth Sciences, and Environmental Energy Technologies Divisions
have already appeared on PBS or soon will.
Judith Campisi of Life Sciences held the anchor position in
the hour-long special "Stealing Time: Turning Back the Clock," which
aired in June. The show focused on researchers pursuing a variety of
approaches to slowing the aging process -- by limiting calories, inhibiting
free radicals, getting plenty of exercise, and using growth hormones,
At the end of the hour, in a refreshing dose of basic science, Campisi
explained with vivid clarity her research on the cellular and molecular
basis of aging. At one point Campisi, a potter by avocation, sliced
successive bits of clay "telomeres" off the ends of model clay "chromosomes"
to illustrate the mechanism that signals cells to stop dividing.
Campisi called efforts to halt aging by preventing the shortening
of telomeres, and thus prolonging cell division, "a dangerous approach"
that could mimic the behavior of cancer cells. "A better approach would
be to restore the function of senescent cells," Campisi said, referring
to cells that live on after they have lost the capacity to divide and
can contribute to tissue malfunction.
"Intimate Strangers" Goes to Chernobyl
Jennie Hunter-Cevera, head of the Center for Environmental Biotechnology
(CEB), and Terry Hazen, a member of CEB and leader of the environmental
remediation technology program in the Earth Sciences Division, both
star in an episode of the PBS series "Intimate Strangers: Unseen Life
on Earth," to air in November.
The episode titled "Creators of the Future" tracks Hunter-Cevera to
the Ukraine, where she and colleagues from the Institute of Microbiology
and Virology in Kiev visit an evacuated and completely abandoned city
near Chernobyl where, she comments, "you can almost hear the ghosts."
The group then travel to the ruins of Reactor 4 to gather soil samples.
Under the Department of Energy's Initiatives for Proliferation Prevention,
Berkeley Lab is cooperating with the Kievan institute in the search
for novel biological products, including enzymes produced by unknown
or mutated microbes in Chernobyl's radioactive environment. Speaking
of her brief excursions into hot areas where even the camera crew was
barred, Hunter-Cevera admits to "a little fear and anxiety," but says
its good because "it keeps you on your toes."
A different legacy of contamination was left at the Savannah River
Site in South Carolina, called by the show's narrator "the most polluted
tract of land in the United States," where reactors produced plutonium
during the Cold War. In another segment of "Creators of the Future,"
Terry Hazen discusses bioremediation methods he pioneered to clean up
one area of the site contaminated by chlorinated solvents.
Hazen pumped methane into the ground to encourage the growth of colonies
of indigenous methanotrophs. "The same enzyme that allows the microbes
to consume methane will degrade the chief contaminant here -- and 250
others as well," says Hazen. In less than two years, the test area was
completely free of contamination. "The smallest of God's creatures have
the potential to clean up our worst problems," he remarks.
These are two prominent examples of what Hunter-Cevera, who returns
for the episode's wrap-up, calls the "Age of Biology," which may supplant
the Age of Machines -- a concept strikingly illustrated by the "Intimate
Strangers" series' spectacular microphotography and quirky animation.
Energy Efficiency Next on NOVA
"NOVA" and "Frontline" are teaming up to present a two-hour program
early next year on energy efficiency in which Alan Meier and Jonathan
Koomey of EETD will be featured players. They were photographed earlier
this month by a crew that included cameraman Bob Elfstrom, the award-winning
cinematographer and codirector of Berkeley Lab's own video, "The Joy
Meier, a ranking editor of Energy and Buildings and Home Energy magazines,
leads building energy measurement and performance analysis in EETD's
Energy Analysis Department. He is noted for the energy-saving features
in his own home, where he greeted the PBS crew at 7:45 in the morning.
"I learned that I need to keep my eye on the producer, not the camera,"
he says, "and to wear solid, pastel colors."
After four hours of taping as he measured electricity leakage in a
neighbor's house and another few hours of on-camera discussion the crew
left for Berkeley Lab to catch up with Koomey.
Koomey is the leader of the Lab's Energy End-use Forecasting Group,
which serves the DOE and the Environmental Protection Agency. "We're
interested in turning data on energy use into useful information," Koomey
says, "for example in calculating how much energy can be saved using
Energy Star appliances versus the standard kind, or driving a compact
car versus an SUV" -- the kinds of decisions people make for themselves.
"We want to make real to people the effects of their choices," he says.
These PBS television specials and the series on aging, new biological
products, environmental clean-up, and energy conservation are bringing
home the contributions of the Lab's researchers to a range of down-to-Earth
issues facing American citizens.

The U.S. Department of Energy has named Berkeley
Lab as co-host of one of two new centers for global climate change research.
Berkeley Lab's center will focus on carbon sequestration -- the capture
and long-term storage of atmospheric carbon dioxide -- in the oceans.
"The Energy Department centers will help coordinate research across
an enormous breadth of disciplines from both government and academia,"
said Martha Krebs, director of DOE's Office of Science. "Breakthroughs
from these centers could lead to new, environmentally acceptable ways
to help address this global problem."
The Center for Research on Ocean Carbon Sequestration, which Berkeley
Lab will co-host with Lawrence Livermore National Laboratory, is to
receive a total of $3 million over the next three years.
From Berkeley, the center will be led by Jim Bishop of the Earth Sciences
Division (ESD), and from Livermore, the leader will be Ken Cal-deira.
Initial collaborators will included researchers from the Massachusetts
Institute of Technology, Moss Landing Marine Labs, the Pacific International
Center for High Technology Research, Rutgers University, and the Scripps
Institute of Oceanography.
In its official announcement of the new centers, the U.S. Department
of Energy stated that the Berkeley-Livermore center will research the
feasibility, effectiveness and environmental acceptability of ocean
"It may be possible to increase the amount of carbon dioxide absorbed
by the ocean through direct injection of carbon dioxide into the deep
ocean or through fertilization of marine organisms, such as plankton,
living in the surface ocean," DOE said in a press release. "Research
will assess the environmental consequences of carbon dioxide injection
and ocean fertilization as well as analyze relevant environmental policies.
Research will combine observations and experiments in the ocean and
computer modeling of ocean currents and the diffusion of carbon dioxide."
High volumes of carbon dioxide (CO2) emissions promote global warming,
and two hundred years of industrialization has resulted in the emission
of an enormous amount of CO2 into the atmosphere. Experts expect atmospheric
CO2 concentrations to double from pre-industrial levels by the middle
of the next century.
Although scientists cannot fully predict the future impact of CO2
build-up, the scientific consensus is that serious environmental consequences
are possible unless the management of CO2 emissions improves.
Earth Sciences Division Director Sally Benson is the co-chair of a
national task force commissioned by the DOE to develop a research roadmap
for investigating carbon sequestration. The goal is to prevent CO2 emissions
from reaching the atmosphere by capturing a significant amount, as much
as 4 billion tons by the year 2050, and securely storing it in the oceans
or in terrestrial ecosystems.
"Science has made the case that a critical factor in global climate
change is the ecosystem -- air-water interaction of anthropogenic carbon
emissions," says Benson. "The idea behind carbon sequestration is to
capture and isolate the carbon at the source of emission or remove it
from the atmosphere."
While most scientists agree that the oceans and terrestrial ecosystems
could serve as natural biological scrubbers for CO2, Benson says that
there is much to be learned before carbon sequestration is put into
practice. In choosing the hosts for its new carbon sequestration centers,
the DOE invited the national labs to submit proposals in collaboration
with other academic institutions. The department then chose the hosts
using a competitive peer review process.
Berkeley and Livermore national labs will head a consortium of institutions
as part of a new center to study the capture and storage of atmospheric
carbon dioxide in the ocean. Another center will focus on carbon sequestration
in terrestrial ecosystems. Atmospheric carbon dioxide is believed to
be contributing to global warming.

In a first for electron microscopy, the One-Ångstrom
Microscope (OÅM) at the National Center for Electron Microscopy
(NCEM) has resolved nitrogen atoms in the presence of more massive gallium
atoms in gallium nitride, in columns spaced only 1.13 angstroms apart.
"The ability to make images of light elements such as carbon, nitrogen
and oxygen in solids at atomic resolution is a very big step forward
-- and it was achieved by a technique that can be a routine tool in
the future," says NCEM's Christian Kisielowski, who with Michael O'Keefe
and their Materials Sciences Division colleagues Christian Nelson, Chengyu
Song and Roar Kilaas recently announced the record-breaking result.
Adds Kisielowski, "This is of great interest to science and industry,"
because many of the most promising solids under investigation today,
including superhard materials, high-temperature superconductors, and
semiconductors with large band-gap energies, incorporate light elements
in crystal lattices at short interatomic distances.
"Seeing small atoms at atomic resolution has always been a challenge,
because they don't strongly scatter the electrons in the microscope's
beam," says Michael O'Keefe. "When the light atoms are close to heavy
ones, it has been virtually impossible to resolve them. Heavy atoms
scatter electrons much more, and as a result the interference pattern
is just too complex to resolve."
Kisielowski explains that "the OÅM overcomes this difficulty
by making a through-focal series of images -- in the case of the gallium
nitride, 20 different images...then uses computer processing to unscramble
the electron waves and combine them into a single high-resolution image.
It's a way of going from the complexity of the lattice images produced
by the OÅM to the simplicity of crystalline structures."
The OÅM has also produced images of columns of carbon atoms
in a diamond lattice, only 0.89 angstrom apart -- that's less than one
ten-billionth of a meter -- in a spectacular demonstration of a promising
technique for extracting more resolving power from mid-voltage electron
In the early 1990s the competition for higher resolution was involving
ever higher voltages and ever more expensive machines, and theorists
sought ways to achieve better results with more reasonable means. O'Keefe
proposed a way to computer-process through-focus images to achieve higher
resolution from a medium-voltage microscope, an approach first suggested
in the late 1960s.
Electron beams are the basis of all transmission electron microscopy,
and through-focus methods depend upon beams with all electrons at nearly
the same energy. Not until the early 1990s did field-emission beam sources
become stable enough for medium-voltage instruments to operate reliably.
"Such a microscope can be designed so that its `information limit'
(the limit to which it produces phase-scrambled information) lies well
beyond its traditionally defined nominal resolution, with all the transferred
information in phase," O'Keefe explains. "By combining information from
many images, a single image with resolution approaching the information
limit can be achieved in practice."
When a group of researchers working in the European Commission's BRITE-EURAM
program set out to build a new generation of high-resolution electron
microscopes using medium voltages, they invited NCEM to be a partner
in the project based on the center's high-resolution expertise and O'Keefe's
theoretical contributions. In 1993, NCEM was able to secure the funds
to acquire a suitable instrument, a Philips CM300.
Although a typical CM300's resolution limit is 1.7 angstroms, O'Keefe
layed out specifications that would optimize the instrument's information
limit. The recent results confirm the OÅM's capacity to produce
phase-scrambled information far beyond 1.7 angstroms.
In the case of diamond, Kisielowski, O' Keefe and colleague Y.C. Wang
showed that the OÅM's information limit extends to at least 0.89
angstrom. And as planned, powerful computer programs used to process
the focal-series images have allowed OÅM to reconstruct spectacular
new images with resolutions near its information limit.
Meanwhile, the ARM -- NCEM's "grandfather" microscope -- is far from
being outmoded by its diminutive descendant. The OÅM can only
produce ultra-high resolution with samples less than a hundred angstroms
thick. The ARM can use samples that are three times thicker and composed
of heavy atoms, yet still achieve a respectable resolution. A high-voltage
microscope can accommodate larger sample holders, which are required
to perform dynamic experiments, such as in-situ straining or heating.
While the ARM will see wide use for years to come, today the ultra
high-resolution performance of OÅM is unsurpassed. The 1.13-angstrom
resolution achieved with gallium nitride, allowing images of its nitrogen
atoms as well as its gallium neighbors, stands as an extraordinary achievement
-- but also as a challenge to Kisielowski, O'Keefe and their colleagues.
Says Kisielowski, "We're aiming to investigate materials with even
shorter bond lengths with the present information limit. We want to
have procedures in place that work reliably and fast to make the experiments
available to our user community as soon as possible. Colleagues from
other laboratories have already started to share our excitement by investigating
their own samples with the OÅM."
Uli Dahmen, head of NCEM, shares Kisielowski's enthusiasm. "This achievement
is based on more than six years of team effort in planning, installation
and testing. After all this time, it's a thrill to actually see it work.
NCEM has reached a very important milestone," he says, and adds:
"The one angstrom barrier has been a Holy Grail for electron microscopists
worldwide...The OÅM makes a truly extraordinary addition to Berkeley
Lab's scientific `toolbox,' and I can't wait to see what new discoveries
it will bring for our users."

Lab Scientists to Participate in Program to Study Aging
On July 15, Berkeley Lab,
UC Berkeley and BioTime, Inc., a Berkeley-based biotechnology
company, signed an agreement creating an endowed program for the
study of the aging process. The program will honor UC Berkeley
professor Paola S. Timiras, who will chair the research committee
and will soon move her group to Berkeley Lab to participate in
the recently-established Center for Aging Research and Education
(CARE). Gathered at the signing ceremony are (left to right) Paul

Wayne T. Pearce, a retired scientist who worked
in the Environment, Health and Safety Division for more than three decades
before retiring in 1996, died on June 20 at the Bayview Nursing and
Rehab Center in Alameda following a short illness. He was 65.
An environmental researcher, Pearce's specialty was air sampling,
according to Richard Harvey, a retiree who used to work closely with
him. "He was one of the hardest workers I ever knew," Harvey said of
his friend and colleague. "Wayne was the epitome of Anglo-Saxon work
ethic. He was very serious, all business. He had many hobbies, including
photography, playing the piano, even attending City Council meetings,
but he was business-like about his hobbies as well."
Pearce was born in Massachusetts and attended Columbia University.
A veteran of the US Air Force, he served at Iwo Jima in 1952. Throughout
his life he was active in community, political and civic affairs. His
interest in environmental issues extended beyond his profession, to
involvement in various ecological causes.
He is survived by his mother Millie Gray Blessing Priest and sister
Lynne Priest Fitzpatrick, both of Greenbelt, Maryland. Services were
held in Massachusetts.

Congress lost "an irreplaceable voice for science
and justice," President Clinton said of Rep. George Brown, dean of the
California congressional delegation, who died on July 15 of an infection
contracted after heart valve replacement surgery in May. He was 79.
An 18-term Democratic congressman and the oldest member of the House of
Representatives, Brown was first elected to Congress in 1962 during John
F. Kennedy's presidency. He served until 1970, gave up his seat for an
unsuccessful run for the U.S. Senate, and was reelected to the House just
two years later.
Brown gained national attention for his early and fierce opposition
to the Vietnam War, but was remembered by his Republican and Democratic
colleagues as a nonpartisan friend of science, civil rights, the environment,
and space exploration.
"With George, a commitment to science always rose above party labels,"
said Rep. F. James Sensenbrenner Jr. (R-Wis), chairman of the House
Science Committee. "America has lost its foremost science advocate."
For Brown, science and technology were more than legislative issues
-- they were his passion. He pushed for development of solar power,
supported space travel, and championed the creation of the Environmental
Protection agency. In 1995 he lobbied to boost the 1996 budget for renewable
energy and energy efficiency programs.
Also a passionate environmentalist, Brown introduced the Sequoia Protection
Act this year to eliminate commercial logging and mining in areas of
Sequoia National Forest. This was the last piece of legislation he sponsored.
With a cumulative 34 years in the House of Representatives, Brown
was the longest serving congressman in California history.
Earlier this year Brown told the New York Times, "From my earliest
days, I was fascinated by science. I was fascinated by a utopian vision
of what the world could be like. I've thought that science could be
the basis for a better world, and that's what I've been trying to do
all these years."
Current and former DOE contract workers who
suffer from a disease caused by their exposure to beryllium at DOE nuclear
facilities would become eligible for financial assistance under a new
Clinton administration proposal. The legislation would reverse DOE's
long-standing practice of opposing most worker health claims.
"This is long deserved and long overdue," said Secretary Richardson
in announcing the initiative. "Many of the men and women who helped
us win the Cold War worked in extremely hazardous conditions and were
exposed to extremely hazardous substances. Those who contracted Chronic
Beryllium Disease (CBD) deserve to receive the same occupational illness
benefits available to regular federal employees."
CBD is a debilitating lung disease caused by exposure to beryllium
-- a metal used by the government in the production of nuclear weapons,
which has been used at 20 DOE sites. While symptoms of the disease can
be arrested with treatment, no cure exists.
The new program will be modeled after the Federal Employees' Compensation
Act program and will be administered by the Department of Labor. All
DOE contract workers, including those employed by the companies who
supplied the government with beryllium products, will be covered.
Benefits to be paid under the program are estimated at about $13 million
per year over the next 10 years. Almost 20,000 workers may have been
exposed to beryllium at DOE sites. To date, DOE screening programs have
identified 115 cases of the disease among current and former workers.
Workers covered by the legislation are eligible to receive reimbursement
for medical costs and compensation for lost wages, permanent impairment
and vocational rehabilitation assistance.

Berkeley Lab will be a key player in Department
of Energy programs aimed at making the Internet an even more useful
tool for scientific experimentation and collaboration than it is today.
Last month, the Department of Energy's Office of Advanced Scientific
Computing Research announced funding for 19 research proposals, of which
the Lab's Computing Sciences Directorate is a partner in eight, with
nearly $3 million in additional funding for FY99 alone. The research
program is part of the Next Generation Internet (NGI) -- a multi-agency
federal R&D program to develop, test and demonstrate advanced networking
technologies and applications.
NGI's goal is to take advantage of greater bandwidth to allow researchers
to quickly and easily access and exchange very large sets of data. It
is currently difficult to provide uniform access to data at various
sites and to allow researchers at different locations to combine and
use that data. NGI is aimed at providing the tools and technologies
to achieve that through the use of advanced networking technologies.
"What we're trying to do is prototype the computing and networking
environment in which scientists will be working in three to five years,"
said Bob Lucas, head of NERSC's High Performance Computing Research
Department. "Our role in nearly half of all the DOE-funded programs
continues Berkeley Lab's tradition of leadership in networking, which
goes back to the early 1980s."
The initiative's first major thrust involves remote visualization
of large amounts of scientific data by researchers at different institutions.
The nationwide scientific community has only a few research centers
with supercomputers and large data-storage tape archives, and far fewer
scientific visualization centers. The goal is to make these centers
remotely accessible and easily usable by scientists collaborating on
"For example, we'd like to make it routine for researchers at Sandia
National Laboratories and the University of Wisconsin to view data generated
at Berkeley Lab," Lucas said.
Berkeley Lab is a partner in three such visualization programs and
the lead lab in two of them: developing a prototype environment for
remote, collaborative visualization of large combustion simulation data
sets; and developing visualization-sensitive network protocols.
Current models for combustion are not capable of handling the huge
amounts of data expected to be generated by the next generation of supercomputers.
This capability is important to help researchers understand the mechanisms
of combustion and to apply this knowledge to solving engineering problems
such as building cleaner, more efficient diesel engines.
Another NGI theme is developing a network infrastructure to share
and access data around the world. Lucas, quoting collaborator Richard
Mount of SLAC, describes this thrust as "competing with UPS to quickly
and efficiently ship bulky data around the country."
Said Lucas, "We will be developing the infrastructure giving users
transparent access to data, no matter where its stored. They'll also
be able to move it rapidly back and forth, say between SLAC at Stanford
and Argonne National Laboratory in Illinois."
Lucas also added that the Lab's achievements in high-performance computing
and networking contributed to the success of its proposals, but even
more convincing was the coordination with colleagues at Argonne and
Los Alamos national laboratories. Other collaborating organizations
include Lawrence Livermore and Sandia national labs, the National Center
for Atmospheric Research, Princeton University, and the Universities
of Illinois, Utah, Wisconsin, and Southern California.
"We coordinated our proposals in such a way that DOE received a sum
greater than the whole of the parts," Lucas said. "Each component will
make the others more effective and useful. We gave them both excellent
technical vision and solid partnerships."
The Department of Energy announced this week
that it is awar-ding $15 million to researchers at 17 universities and
nine DOE laboratories for research on the Next Generation Internet.
Nineteen projects will be funded over three years. In addition to
Berkeley Lab, participating labs are Argonne, Brookhaven, Fermilab,
Los Alamos, Livermore, Sandia, SLAC, and the Thomas Jefferson National
Twelve projects are basic technology projects to develop the underlying
network architecture and monitoring technologies needed to support scientific
Internet traffic. Five will integrate and test the technologies on DOE-related
research and two are university testbeds to link the new tools to researchers
Grigory Barenblatt, one of Russia's most distinguished
applied mathematicians who now holds a joint appointment in Berkeley
Lab's Computing Sciences Division and the math department at UC Berkeley,
has been awarded the Maxwell Prize, a new international honor in applied
Barenblatt is an expert in the analysis of problems dominated by complexity.
He, along with colleague Alexandre Chorin, made headlines a year ago
with the discovery of a flaw in the "Law-of-the-Wall," an aerodynamic
equation that had been a standard for 60 years. His work on the formation
of cracks in solids was the basis of many of the tools used today in
the analysis of failure due to fatigue.
"The range of Barenblatt's achievements is truly breathtaking," said
the International Congress on Industrial and Applied Mathematics in
awarding him the prize.
Barenblatt is a foreign associate of both the National Academy of
Sciences and the National Academy of Engineering, and a foreign honorary
member of the American Academy of Arts and Sciences.
Established this year, the Maxwell prize was named for the great 19th
century Scottish physicist James Clerk Maxwell; it provides international
recognition to a mathematician who has demonstrated originality in applied
The National Energy Research Scientific Computing
Center (NERSC), which provides high-performance computing and data storage
resources to Department of Energy researchers, is now accepting applications
for allocating resources for FY2000.
Applications for the coming fiscal year will be accepted through Wednesday,
Aug. 4. Award letters will be sent out on Sept. 20, and awarded allocations
will take effect Oct. 1.
The allocation process, called ERCAP (Energy Research Computing Allocation
Process), is entirely web-based, and applications must be submitted
using a web-based form. For more information visit the website at http://ercap.nersc.gov.
Earlier this year DOE announced a new policy of broader scientific
peer review for the use of NERSC, the Department's largest unclassified
scientific computing facility. As proposals are submitted, they will
be subjected to peer review to evaluate the quality of science, how
well the proposed research is aligned with the mission of DOE's Office
of Science, and the readiness of the specific application and applicant
to fully utilize the computing resources being requested.
NERSC, which marks its 25th anniversary this year, recently announced
that it has selected an IBM RS/6000 SP system as the center's next-generation
supercomputer. The final system will have 2,048 processors and a peak
speed of 3 teraflops (three trillion calculations per second). Installation
of the first phase of the IBM system began in early summer.
NERSC also operates a 677-processor Cray T3E-900 supercomputer. Additionally,
for FY2000, NERSC expects to allocate time on 64 SGI/Cray SV1 processors
and 32 SGI/Cray J90se processors. The center also provides archival
data storage in its High Performance Storage System, with a total capacity
of 300 terabytes. For more information about the NERSC High Performance
Computing Facility, visit the website at http://hpcf. nersc.gov. --

Jennie Hunter-Cevera was working for the Bristol-Myers
Squibb pharmaceutical company when she received an ultimatum from her
boss: find a new antibiotic in three months, or you're gone. Fortunately,
Hunter-Cevera, now the director of the Lab's Center for Environmental
Biotechnology, had faith in her unique ecological approach to searching
for microorganisms. Her method was based on the premise that there is
a connection between an organism's physiology and its environment.
"I just had to think like a microbe and get in the mud," she says.
She made the discovery in Wading River, New Jersey. Later, upon receiving
her Ph.D. from Rutgers University, her mentor gave Hunter-Cevera a lab
coat decorated with a painting of the salt marsh where she did her fieldwork
and where she found some of the microorganisms.
Hunter-Cevera developed the thread by which she could screen for compounds
under the conditions in which they are naturally found. Her theories
were both successful and fruitful.
"I think most great discoveries often are serendipitous and simplistic.
You only find what you look for, and sometimes it's in your backyard."
The lab coat is currently being featured in a large exhibition called
"A State of Health: New Jersey's Medical Heritage" at Rutgers University.
Hunter-Cevera discovered a bacterium in a New Jersey salt marsh that
produced a major new class of antibiotics in 1978.
"The lab coat is a vivid reminder that the discovery of antibiotics
has been done by real people who are willing to literally dig in the
dirt," says curator of the exhibition Karen Reeds. "It's also a reminder
that the natural world still is a vital source of new therapies -- yet
another reason for environmental conservation."
Jennie Hunter-Cevera calls herself a lover and student of nature,
and she continues to search for new antibiotics in nature while here
at the Lab. "When you're conserving plants and animals, you are also
conserving the microorganisms, even though you can't see them," she
Now dressed in a plain white lab coat, Hunter Cevera adds, "the message
the coat sends is that if you want something, make it happen."
After her 1978 discovery, Hunter-Cevera went on to make numerous discoveries
and publish many of her findings. Currently she is developing new products
and processes to benefit human health and environment at the Lab.

Starting Aug. 30, groups will be able to reserve space at the cafeteria
by using the Facilities Department's conference room website at http://ox.ee.lbl.gov/conf_rooms/.
Listings for the downstairs dining room, Perseverance Hall, the main
dining hall, and cafeteria lobby will include photographs and information
on room capacity and services available. Cafeteria space may be reserved
for lunches, meetings, exhibits and other functions. The lobby and its
large bulletin board are available for displays having to do with Berkeley
Lab's scientific programs and related activities.
The conference room website allows users to select a suitable meeting
place from a number of locations around the Lab and make a firm reservation.
For meetings scheduled in the cafeteria, the site will prevent duplicate
reservations and conflicting uses. The cafeteria is available Monday
through Friday during normal working hours and evenings.
For more information on cafeteria reservations, contact the Work Request
Center at X6274 or firstname.lastname@example.org.

Berkeley Lab's Summer Lecture Series concludes on Aug. 4 with a talk by
Don DePaolo of Earth Sciences about "Drilling Through a Volcano to Uncover
Secrets of Deep Earth."
Head of the Lab's Center for Isotope Geochemistry, DePaolo is one of the
leaders of the Hawaii Scientific Drilling Project in Hilo. His team will
drill through a large volcano to sample lava flows dating back 600,000
years at a depth of about 6,000 meters -- slightly more than the depth
of the ocean -- into the 80-million-year sea floor underneath.
Also a professor of geochemistry at UCLA and UC Berkeley, DePaolo
has been a senior scientist at Berkeley Lab since 1988.
The Summer Lecture Series is co-sponsored by the Public Information
Department and the Center for Science and Engineering Education.
