DOE honors Computing Sciences' Merola for role in ESnet development

By Jeffery Kahn

When you think of computer networks, wires and routers and protocols come to mind. But the secret to a free-flowing network, says Jim Leighton, who manages the ESnet network linking DOE Energy Science research sites, is getting people to work together.

"Cooperation between every site on the network is the key," Leighton said. "Sandy Merola has been instrumental in forging the cooperation that distinguishes ESnet. He is one of the key architects of ESnet."

For the past seven years, Merola, deputy director of Computing Services here, has chaired ESnet's steering committee. It is composed of member scientists who are users of the network and includes site and distributed computing coordinating subcommittees. According to Steve Wolf, former head of the National Science Foundation's computing and networking group, this group is the single-most effective committee in government.

With the move of ESnet headquarters from Livermore to Berkeley, Merola has stepped down as chair of the committee but remains a member. Two weeks ago, Dave Nelson, director of DOE's Office of Computational and Technology Research, came to the Lab to honor Merola for his service.

Nelson presented Merola a plaque signed by Martha Krebs, director of DOE's Office of Energy Research. It reads: "In recognition for outstanding and visionary chairmanship of the Energy Science Network (ESnet) Steering Committee from 1989 to 1996. You led the ESSC through a major upgrade of the network's capabilities and through a reorganization of the committee's concerns to a greater focus on the role of the network in enabling research. The result is that ESnet is truly DOE's network for the future."

Merola said the steering committee he chaired must foresee future network needs of researchers such as video-conferencing, distributed computing, and the ability to remotely operate DOE national user facilities. "We spell out future needs," he said, "but the real implementation is done by the ESnet staff and the committee members at their respective sites."

Merola said networks are evolving very quickly. Around 1970, the first traffic began to flow over computer networks at the rate of about 40 words a second. Today, ESnet moves about one million words a second.

"Right now," he said, "ESnet is the world's fastest and most respected production computing network. Jim Leighton and his staff deserve much of the credit for ESnet's success. We can do things that were inconceivable 20 years ago. The job from here is to be able to say the same thing in the decades ahead." n

ESnet brings high speed to international networking

By Jeffery Kahn

Puzzled by the recent rash of national news articles about the slowdown of the Internet? If you think these reports lack the ring of truth, it's because of the ESnet, the Energy Sciences Network.

The ESnet is the high-speed network linking DOE Energy Science research and collaborator sites around the globe. When you send or receive information over the Internet, it travels, at least in part, over ESnet, probably the most robust and reliable part of the global Internet.

ESnet, along with the National Energy Research Scientific Computing (NERSC) Center, is now headquartered at Berkeley Lab. Jim Leighton, the leader of ESnet since its inception, will manage it here as head of Computing Services' Networking and Telecommunications Department.

Leighton, who has degrees in physics and electrical engineering, began work in networking in 1985. Here, he will oversee an ESnet staff of 20 people. Running ESnet, however, entails global responsibility.

"Managing ESnet is as much sociology as anything else," he said. "In order for the net to work, every laboratory and site on it--from Berkeley to Brookhaven to CERN--has to cooperate. We like to say that in terms of the number of sites involved, it's the largest collaboration within DOE."

ESnet is said to be one of the few islands of stability in the chaos of the Internet. There are multiple reasons underlying ESnet's reputation for reliability. Leighton says these include a shared ethic of cooperation and excellent two-way communication between users and the network's managers and planners.

Unlike much of the rest of the Internet, the ESnet is a restricted access information superhighway. That is, use is restricted to senders of information who are part of the ESnet community or to those sending information to ESnet sites. The amount of traffic that a network can handle is referred to as "bandwidth." The more bandwidth, the more packets of information that can be transmitted. Much of the information traveling on the greater Internet is slowed by a lack of adequate bandwidth. That is not the case with ESnet. ESnet is continuously upgraded so that its supply of bandwidth matches or exceeds the growing demand for it. ESnet curently can handle data flows of up to 155 million bits-per-second.

Leighton says that ESnet's roots date back more than a decade. Prior to ESnet, DOE had a 50 thousand-bits-per-second network to link NERSC to its users. Around 1985, the need for a new network design became manifest. DOE wanted a faster network that also would link all its Energy Research sites. Five years later, ESnet began service with the debut of a T1 (1.5 million bits-per-second) network.

Over its brief history, ESnet has evolved to a point where increasing portions of the physical network are provided by private telecommunications vendors. During these years, the number of linked sites and the quantity of traffic has grown dramatically. Leighton says that in order for the network to keep up with the growth in traffic, ESnet has had to play the role of catalyst with the private communications industry.

In 1992, ESnet became an advocate of Asynchronous Transfer Mode (ATM), helping to shape the future architecture of the Internet. ATM is a standard that allows data, voice, and video communications to travel in a mixed stream through the same network at a very high rate of speed.

"ESnet is not a testbed but a working production network," Leighton said. "Yet to keep up with future demand, we must stay on the leading (but not bleeding) edge of technology."

ESnet signed a contract with Sprint in September 1994. A year ago, five ESnet sites were linked by the first national production ATM network, which ran at speeds of 45 million bits-per-second. Since then, eight more sites, including Berkeley Lab, have been added, and two sites were upgraded to 155 million-bit-per-second rates. ESnet's successful deployment of ATM has, in turn, accelerated the introduction of this technology into the private marketplace.

This fall, the ESnet will be upgraded here. At that time, a 622 million bit-per-second ATM test link will be built between the Lab and a Sprint facility in Burlingame. n

DOE to seek new set of 5-year contracts with UC

By Ron Kolb

Department of Energy Secretary Hazel O'Leary announced this week that DOE will seek another set of five-year contracts with the University of California to manage the labs in Berkeley, Livermore and Los Alamos.

Berkeley Lab Director Charles Shank said he welcomes this week's announcement. "This will assure that the historic relationships we have had with the University, and the synergy that exists between the three laboratories and the nine UC campuses, will be able to continue and grow," he said. "The new contracts can only strengthen our collective research efforts on behalf of the DOE and the nation."

The University's Board of Regents had previously endorsed talks with DOE about renegotiating all three contracts, which expire in 1997. If the Regents formally authorize negotiations, UC officials will work with DOE representatives to develop new contracts extending to the year 2003.

"In the 53 years that this partnership has existed, both parties and the American public have reaped enormous benefits," Shank said. "UC is uniquely qualified to bring an extraordinary sense of values and openness to the labs."

He especially noted the collaborative efforts between Berkeley Lab and the UC Berkeley campus, which will flourish under the new contract into the millennium. These include research in life sciences--such as the genome program--in fusion energy, and in computation. More than 250 Berkeley Lab scientists have joint faculty appointments with UC campuses, and more than 600 students pursue advanced degrees here.

O'Leary cited Berkeley Lab's excellent scientific and technical performance, as well as UC's leadership "in pathbreaking energy research programs which have increased the efficiency of U.S. energy use and decreased costs to U.S. energy consumers. The University's record of scientific achievement at the three laboratories and its reputation for `world class' science are unparalleled."

In recognizing the University's long-standing relationship with the federal government, President Bill Clinton said, "Over the last five decades, the University of California has made an enormous contribution to our success in winning the Cold War. We look forward to working with the University of California to promote both our economic and national security."

O'Leary expressed DOE's commitment to bringing management improvements and greater accountability into its contracts and indicated that the Department would seek important changes to the current contracts. As a condition of extension, she said the new contracts must embody the objectives of DOE's Contract Reform Initiative, including greater use of results-oriented performance and results-based payment.

The DOE announcement also stated the contracts must provide for enhanced oversight by DOE in important areas of business and financial management, with special attention given to Los Alamos. The New Mexico laboratory has been dealing with issues involving its local neighbors and its environmental, safety and health programs. n


Study finds exercise, not genetics, major determinant of weight

By Jeffery Kahn

You can out-run your genes for weight but not your genes for good cholesterol. That's the conclusion reached from an analysis of identical twins, performed in an ongoing National Runners' Health Study.

Life Sciences Division's Paul Williams, who heads the study, said the research contradicts conventional wisdom, which holds that weight and height have about the same degree of inheritance.

"Exercise appears to be able to nullify a genetic tendency toward being overweight," he said. "It also elevates the level of good cholesterol but not enough to eliminate its genetic determination."

Funded by the National Institutes of Health, the study involved 35 pairs of identical twins identified through Runner's World magazine. Each twin pair had a runner sibling and a sedentary sibling. The runner ran an average of 39 miles per week while the sedentary twin averaged less than five miles per week.

Much to their surprise, researchers found that the twins' weights showed very little correlation. Rather than genetics, exercise appeared to be the determining factor of each runner's relative weight.

Researchers classified each of the 25 male and 10 female twin pairs according to their body mass index (BMI), computed by dividing a person's weight in kilograms by the square of their height in meters. For instance, a 5-foot, 5-inch-tall woman (1.65 meters) who weighs 150 pounds (68 kilograms) has a BMI of 25. According to the 1995 Dietary Guidelines for Americans, a BMI of more than 25 classifies one as overweight.

Based upon their BMI, 13 of the sedentary twins were overweight compared to only two of the runners. None of the runners with an overweight sedentary twin were themselves overweight.

Williams said researchers decided to go a step further, assessing the similarity of the twins' weights. Height, which is strongly inherited, was strongly correlated in the twins, whereas weight was not. Height had a correlation of 0.9, whereas (because of weight differences), the twins' BMI had a correlation of only 0.2.

The twins also were measured for high-density lipoprotein (HDL) cholesterol, the so-called good cholesterol. Men and women who have high levels of HDL are generally at less risk of having a heart attack. The recommended approaches to raising HDL levels are exercise and low body weight.

Berkeley Lab researchers found that the running twin typically had higher levels of good cholesterol--on average, 10 percent more--than their sedentary twin. However, despite substantial differences in exercise and weight, the twins' HDL levels were still surprisingly similar (correlation of 0.7).

"These results underscore the importance of the genetic determinants of the good cholesterol," Williams said. "That's not to discount the importance of promoting vigorous exercise or weight loss. After all, we can exercise more and lose weight, but there's not much we can do about our genetic make-up."

Williams' co-authors in the study are Berkeley Lab's Davina Moussa, Elizabeth Noceti, Patricia Blanche, Richard Terry, Yan Huang, and Ronald Krauss.


Women in Science & Engineering Seminar

The next speaker in the Women in Science and Engineering seminar series is Joan Daisey of the Energy and Environment Division. She will speak on "Sick Building Syndrome and Complex Mixtures of Volatile Organic Compounds" at 12:10 p.m. on Monday, May 20, in Bldg. 70A-2277. Refreshments will be served at noon. All employees are invited to attend.

Volatile organic compounds (VOCs) are suspected to contribute significantly to "Sick Building Syndrome" (SBS), a complex of subchronic symptoms that occur during occupancy of the building in question. Prior attempts to link exposures to VOCs and symptom outcomes have not been generally successful. Now it has been possible, for the first time, to link SBS irritancy symptoms to low level exposures to VOCs.

Daisey is program head of E&E's Indoor Environment Program, which conducts research on indoor air quality and energy use in buildings.


In Memoriam
Richard F. Johnson

Richard "Dick" Johnson, a retired technical editor with the Technical and Electronic Information Department, died on May 6 following a year-long battle with cancer. He was 64.

Johnson joined the Laboratory in 1980 after working 20 years for publisher W.H. Freeman in San Francisco. In addition to his editing background, Johnson had a degree in geology, so most of his editorial assignments were with the Earth Sciences Division. According to former supervisor Loretta Lizama, Johnson was a very meticulous, detail oriented person, working on everything from annual reports to research papers. He retired from the Lab in 1993.

Johnson had a great interest in opera, and was an avid bird watcher. In this field, he proved to be a great resource for fellow bird enthusiasts.

Johnson is survived by his wife Claire and daughter Catherine. A memorial service will be held at 2 p.m. on May 26 at the community center in Joaquin Miller Park, Oakland. Friends wishing to make contributions on Johnson's behalf may donate to either the National Cancer Institute or the Point Reyes Bird Observatory.


N e w s w i r e


The request for Congress to put up $450 million for U.S. participation in the Large Hadron Collider project at CERN, which was made last month by DOE Energy Research head Martha Krebs (see Newswire, 4/5/96) has so far not been greeted warmly in the Senate. At a hearing held by the energy R&D subcommittee, chair Pete Domenici (R-N.M.) expressed his doubts and asked DOE to provide detailed data comparing the LHC's capabilities with those of the late SSC. Bennett Johnston (D-La.), who was a strong supporter of the SSC, said "I am highly skeptical of spending $450 million on a foreign machine." Negotiations between DOE, NSF, and CERN resulted in the funding request which would make the U.S. the largest user nation of the LHC. The senators were also lukewarm about U.S. participation in the International Thermonuclear Experimental Reactor.


This May is not only welcoming in the flowers, it is also welcoming two additions to the national lab family. On May 1, Secretary of Energy Hazel O'Leary was on hand to help dedicate Argonne's Advanced Photon Source. The $812 million facility was completed on-budget and ahead of its five-year construction schedule. Like Berkeley Lab's Advanced Light Source, the APS is a third-generation synchrotron radiation source. Unlike the ALS, which produces low-energy or "soft" x-rays, the APS produces high-energy or "hard" x-rays. O'Leary is also scheduled to attend the dedication of the Continuous Electron Beam Accelerator Facility in Newport News, Va., which will take place on May 24. With a design energy of 4 GeV, CEBAF is billed as "the world's most powerful microscope for studying the nucleus of the atom." The facility, which is managed by the Southeastern Universities Research Association, cost approximately $600 million to design and build. Since CEBAF's inception, the project has been overseen by its director, Hermann Grunder, a former deputy director here.


This May has also brought in not-so-welcome news for astronomers. The National Optical Astronomy Observatories (NOAO) has announced a plan in which four of its five Kitt Peak telescopes would be closed as early as 1999. The hit list includes the 4-meter Mayall telescope, which is a favorite of astronomers at small colleges and state universities. As always, a budget crisis is behind the closures. A flat budget of $26.7 million from NSF, the chief-funding source of NOAO, is projected for FY97, dwindling to $22.4 million by the year 2000. Meanwhile, the British government has dealt what Science magazine called a "potentially fatal blow" to the Royal Greenwich Observatories and the Royal Observatory, Edinburgh. The RGO and ROE, which trace their origins to the 17th and 18th centuries, will now face stiff competition from other public and private organizations for Britain's $26 million-a-year ground-based astronomy program.


Like a page from the "Sorcerer's Apprentice," the use of automated DNA sequencers is producing a flood of genetic data that is overwhelming the U.S. Patent and Trademark Office (PTO). Private companies that specialize in DNA sequencing, particularly Incyte Pharmaceuticals of Palo Alto, and Human Genome Sciences of Rockville, Md., have been sending in applications for patents on raw DNA sequences at a torrential rate. As a consequence, PTO officials say it could take more than 90 years to examine those sequences that are already in the queue. Even scarier news: Incyte and HGS have their sequencers running 24 hours a day, seven days a week, and both plan to add more machines.


Lab/UC reduction-in-fee policies make higher education irresistible

By Christa Brothers

In the last four years, Christine Doughty of the Earth Sciences Division has twice donned cap and gown to receive academic degrees from UC Berkeley--her masters' degree in 1991, and her doctorate in hydrogeology last fall. She did it while working full time, and with considerable financial assistance from both the University and the Laboratory.

As an employee within the UC System (as are all Berkeley Lab employees), Doughty received a substantial reduction in fees once she met UC's admissions requirements. Last semester, there were 14 Lab employees who participated in this program at the undergraduate and graduate levels. Employees are allowed up to 6 hours of time off with pay per week to travel to and attend classes that are not available during non-working hours.

Doughty worked at the Lab for 10 years before returning to school. "When I first went back to graduate school," she said, "I was just amazed at how exciting it all was." She said that although working and going to school was a challenge, she was able to work out a flexible schedule with her supervisor. "People (at the Lab) were very understanding about scheduling meetings during times I was here."

Henry Tran of the Environment, Health and Safety Division was also able to work out a schedule that allowed him to complete a master's degree--his second--in mechanical engineering. He is now working towards a Ph.D. in computer modeling.

He said one of the reasons he decided to apply for a job at the Lab was because of the educational benefits offered here. UC reduces the tuition and registration fees by two-thirds for any degree that Berkeley Lab employees decide to pursue. "Right now I am paying about $900 per semester," he said. The Lab will then reimburse two-thirds of the balance if the degree program is related to the employee's position or career. Tran's bottom line will be only $300 per semester, as opposed to about $2,700.

Tran's advice to other employees who may be considering a return to school? "It may be difficult for people who think they are too old to apply to Berkeley, but just go down to Sproul Plaza and look at the students. There are all ages, young and old."

To find out more about this educational opportunity, check out the Employee Development and Training Unit's web site ( or call X4238. n

Campus bus to take over yellow flag run

Beginning Monday, May 20, the Lab's "yellow flag" shuttle that runs between Hearst Mining Circle on campus and the Bldg. 62-66 area will be phased out and replaced by a UC Berkeley bus that runs between campus and the Lawrence Hall of Science.

During a four-week transition period starting May 20, the Lab's yellow flag shuttle will reduce its schedule from 15-minute intervals to 1/2-hour intervals. The campus bus will add the Lab stops to its run on a 1/2-hour schedule interleaved with the Lab shuttle, in effect, maintaining a 15-minute schedule. The service will run from 7:45 a.m. to 6:15 p.m. from Hearst Mining Circle.

The last day of the Lab's yellow flag service will be Friday, May 17. From that point on, the campus bus will take over the schedule completely, maintaining its 1/2-hour schedule. Berkeley Lab riders will need to show their Lab ID cards for a no-fare ride on the campus buses, which are equipped with bike racks.

See the schedule below for departure times. n

Schedule for new campus/LBNL bus service

The following schedule will begin Monday, May 20. For the first four weeks, the Lab's yellow flag service will also run at 1/2-hour intervals in-between these times. Beginning June 17, only the campus bus will operate.

Java files could create havoc for Netscape users

Users of Netscape should be wary of downloading Java files on the World Wide Web, warns Lab Computer Protection Program manager Mark Rosenberg.

"So far," Rosenberg said, "there have been no reports of problems here. However, there is a potential for mischief and worse. Theoretically, a hostile Java file could destroy information on your computer or send e-mail as though it came from you."

Java, which was developed by Sun Microsystems, allows Netscape to download active programs that can perform a range of applications. Both Netscape and Sun are working on but have yet to resolve all security issues posed by Java and Javascript. Web browsers other than Netscape are not vulnerable because they cannot import these Java files.

Rosenberg said anyone who thinks they have a problem should send e-mail to him at [email protected].

Those who want to be absolutely certain they do not experience problems can modify Netscape so that it cannot import Java. To do so, boot Netscape and under the Options pulldown menu, select "Security Preferences." Then click on the "General" option. Mac users should check the box that says "Disable Javascript." PC users should check that box as well as a second box that says "Disable Java."

Free skin cancer screening clinic

8 a.m. - noon, Friday, May 31, Bldg. 26

Health Services is offering the skin cancer screening clinic at no cost to employees for the eighth consecutive year. Appointments are available between 8 a.m. and noon on Friday, May 31, in Bldg. 26. Berkeley dermatologist Elizabeth Ringrose will conduct the screenings. Employees with some of the symptoms or risk factors described below may especially want to participate. Contact Health Services at X6266 for an appointment; please plan to take the Lab shuttle as parking is limited.

Skin cancer commonly takes on of three forms, depending on the types of cells it affects. Malignant melanoma, the rarest but deadliest type, accounted for approximately 34,000 cases and 7,200 deaths in 1995. It starts in melanocytes, the cells that give skin its pigment. The other two more common forms--basal cell carcinoma, afflicting 640,000 people in 1995, and squamous cell carcinoma, striking 160,000 in 1995--arise from those two types of unpigmented cells. These cancers grow slowly and almost always stay in one place. However, if they are left untreated, they can penetrate underlying tissue.

With summer approaching everyone should know the warning signs of possible melanoma and the appropriate precautions. Here are some tips from Health Services:

The most significant risk factor for skin cancer is exposure to sunlight. Men have a higher incidence of skin cancer than women, partly because they tend to work outside more often. Since sun damage is cumulative, older adults are at increased risk. Skin cancer can strike anyone, but those with fair skin and freckles, blond or red hair, and blue or green eyes, as well as anyone who has had skin cancer before or who has a relative with the disease is at a higher risk.

Skin cancer shows up as growing moles colored in various shades of brown, red, black or navy blue. Get to know the moles and bumps on your skin; the Skin Cancer Foundation advises a skin self-exam every three months, using a mirror and a buddy to check hard-to-see spots such as the scalp and back. It is easy for a doctor to miss skin cancer in an early stage as the changes may be very subtle, so it is important to be your own best skin-watcher, consulting with your doctor when you notice a change in something.

Most moles are benign. This checklist can help to identify those that may need medical attention:

Such changes do not necessarily indicate melanoma, but should be checked by a doctor.

The disease can be avoided by minimizing sun exposure.

Where's the menu?

Although it has been a long-standing tradition to include the cafeteria menu in Currents each week, survey and word-of-mouth have told us that it is the least read item in the paper. In the interest of more effectively using the space now allotted to the menu, we are discontinuing it on a trial basis. For you diehard (but all too few) diners who count on having a menu each week, printed copies will continue to be available for pick-up inside the cafeteria entrance.


New Library services

Need a journal article or a book that the Berkeley Lab Library doesn't own? In a continuing effort to make information more accessible, the Library is offering two new services.

The first is UnCover, an online order system that gives employees access to a table of contents index and article delivery service for approximately 17,000 magazines and journals and 6 million articles. UnCover allows users to order journal articles themselves and have the material faxed to them within an average of 24 hours; for certain articles, within an hour. Since this is an experimental service, there is no cost to the employee unless the Library already has a subscription to the journal or the cost for the article is more than $25. Users must provide their employee number in order to get into the system.

To get onto the UnCover system, go to the Library's Web page ( Click on UnCover under the Database and Databanks section. There you will find information about setting up a password and hints on searching the database. The telnet link to the system is also located on that page.

The second service is a new InterLibrary Loan request form on the Web. This form supplements the UnCover system because it allows users to request that material not available through UnCover be ordered by the Library. Using a Web form, users can enter the information about the document they need and submit that information to the Library. The Library staff will then order the material using their other sources. Material ordered through the Library via the InterLibrary Loan form will continue to have a $10 fee attached. The form is available from the Library's home page ( and at the bottom of the UnCover page .


LHS shrinks the Bay Area

On Saturday, May 18, thousands of LEGO bricks and blocks will be transformed into famous Bay Area landmarks--including the Palace of Fine Arts, Oakland's Federal Building and Paramount Theater, SF Museum of Modern Art, Bay Bridge, Berkeley City Club and UC Berkeley Campanile--as young builders and volunteer architects have fun constructing remarkable models at the Lawrence Hall of Science.

Construction will take place on the LHS plaza; children 5-16 years old are invited to participate as builders. The event, co-sponsored by the East Bay chapter of the American Institute of Architects, is designed to engage the interest of the public, particularly children, in the elements of planning, design, and teamwork, as well as the spectacular nature of Bay Area architecture.

Builders and visitors may also explore Invention Adventure, the featured exhibit of hands-on building activities, giant models, and machines all made entirely of LEGO bricks.

Registration is 10 a.m. to noon, construction 11 a.m. to 3 p.m., and demolition party 3-4 p.m. Participation is on a first-come, first-served basis.
