The task force also called for serious negotiations with Russia toward a follow-on arms control agreement to replace the Strategic Arms Reduction Treaty, which expires at the end of 2009, with the goal of further reductions in their stockpiles.

Labs seek direction

With so little weapons work to do, the national laboratories and other weapons infrastructure are increasingly looking outside NNSA for work. “We have a vast amount of expertise that is not available anywhere else . . .

including sensor and detection technology, high-performance computing, microsystems, chemical and biological detection technology, and explosives science,” D’Agostino said.

The weapons design laboratories, LLNL and LANL, each have shed 2000 employees over the past two years, LLNL director George Miller said. Capabilities developed in the design of nuclear weapons frequently have applications elsewhere. One example is nuclear forensics, the science of pinpointing the origins of a nuclear device that terrorists might detonate. In that highly specialized field, he said, “it takes a nuclear weapons designer to find [another designer].” But lacking new weapons projects to design and build has made it increasingly difficult for the labs to recruit a new generation of scientists and engineers. As Chilton noted, “you can study rocket science for as long as you want, but if you don’t build a rocket factory, you can’t get to the Moon.” The task force report calls for broadening the missions of the weapons laboratories to include energy security, a change that could help them recruit and retain new talent.

Miller said many policymakers mistakenly believe that the science-based stockpile stewardship program, which had brought billions of dollars in new experimental facilities and supercom-

puting capabilities to the weapons labs since the cessation of nuclear testing in 1992, has been completed. In fact, major new facilities such as the National Ignition Facility at LLNL and the DualAxis Hydrodynamic Radiographic Test Facility at LANL are just now coming on line, and years of experiments designed to spot potential flaws in the nuclear arsenal lie ahead.

Science on the cheap

The missions of the national laboratories have grown dramatically over the past several decades, said Frances Fragos Townsend, former homeland security adviser to President Bush; they now include increasing amounts of “work for others” performed under contracts with federal agencies such as Defense and Homeland Security. Townsend, who is cochairing a task force for the Henry L. Stimson Center that is looking into leveraging the national laboratories’ S&T capabilities, said DOE has become the “landlord for a significant share of the national security S&T capabilities needed throughout the government.“ But she said the DOE labs “have provided science on the cheap” for those agencies, which haven’t been required to share the cost of necessary long-term investments. And although customer agencies have been “comfortable” working with the labs, Townsend said, due to a shared history of R&D on sensitive security matters, she warned that the labs risk losing their customers to other research performers if they don’t keep their costs down. “[The labs’] overhead is high, and if they care about their longterm viability, they’re going to have to learn to compete better,” she said.

LANL director Michael Anastasio said the labs could make a good case for a piece of Obama’s economic stimulus plan, which the president-elect has said will include rebuilding the nation’s infrastructure. “What higher-leverage investment is there than science and technology?” asked Anastasio.

national laboratories receiving federal funding need to show they are in compliance with Title IX. “That’s bedrock,” says Rolison. “The federal funding agencies have a regulatory responsibility to audit their grantees with respect to Title IX. Now it’s just a matter of doing it. We’re in the early stages.”

Not just sports

Enacted into US law in 1972, Title IX is known for opening up high-school and university athletics to women. But it makes no mention of sports:

No person in the United States shall on the basis of sex, be excluded from participation in, be denied the benefits of, or be subject to discrimination under any educational program or activity receiving Federal financial assistance.

In 2000, fed up with the persistent low numbers of women in her field, Rolison wrote an editorial for Chemical and Engineering News. In it, she asked: “Is it time to convince Congress to ‘Title IX’ U.S. chemistry departments for their entrenched inability to increase the number of women represented on their faculties? In other words, should federal funds be withheld from those universities that do not increase their faculty hires to reflect the pool of U.S.- granted chemistry Ph.D.s—one third of whom are women?” Rolison started giving talks around the country. She originally titled her talk “Title IX for Women in Academic Chemistry: Isn’t a Millennium of Affirmative Action for White Men Sufficient?” It evolved to “Leading Professional and Institutional Change through Subversion, Revolution, and Meteorology.”

“Lawsuits by individual women haven’t been working,” says Rolison, explaining why she advocates applying Title IX to university science, technology, engineering, and math (STEM) departments. She adds that when she talks to people, “the knee-jerk reaction is that you can’t hire women because they don’t apply. But a university fires a basketball coach if he isn’t out on the road scouting for new talent. That is what department chairs need to do. Recruit.” Another thing she hears a lot is, “We don’t want quotas.” To that she says, “Get over it! We’ve always had preferential hiring—it was just 90% white guys.”

As for the climate—the “meteorol- ogy”—of physics and other maledominated fields, Sherry Yennello, a chemist at Texas A&M University, says, “Physicists are the most creative prob-

examples to others—for example, during a recruiting weekend for students accepted for graduate study the physics department hosts a breakfast for females to meet with female faculty members. Another example is a problemsolving course that Durand and her husband, also an emeritus faculty member, developed to help students prepare for the qualifying exam. “Not a single woman who has gone through the course has failed,” says Durand. “Our experience is that each and every review has made a positive impact,” says a DOE spokesperson. “If deficiencies in a program have been found, the institutions have acted promptly on our recommendations.”

If a department were found to not comply with Title IX, “NASA would not move to impose the ultimate sanction of funding withdrawal unless all efforts to bring the school into voluntary compliance failed,” says Sharon Wagner, the agency’s Title IX program manager. And, although NASA has not found noncompliance, she adds, the reviews provide recommendations “for enhanc-

ing existing equal opportunity efforts.” For example, NASA has suggested that universities and departments publicize information about their Title IX coordinators; revise internal procedures for filing complaints about harassment and discrimination; determine whether complaints of alleged inappropriate behavior have merit; portray gender diversity on websites; and conduct ongoing self-evaluations on admissions, enrollment, graduation rates, financial aid, and treatment of students.

Are universities nervous about these reviews? “If a university is not in compliance, there is danger. But we were confident that our practices were along the guidelines,” says Balantekin. “While we are at it,” says Rolison, “the data need to be looked at across ranks— students, staff, faculty—and then disaggregated by sex, race, and ethnicity. Title IX has never not worked to make things more equitable. It can also be applied on behalf of men.” And, she notes, “no university ever lost money for sports” for not complying with Title IX.

DOE invites partners in green technology

“Entrepreneurs-in-residence” aim to spin off labs’ energy technologies.

The US Department of Energy is more than doubling the number of its national laboratories that are partnering with venture capital firms to bring green energy technologies to market. While DOE is still waiting to see if any new businesses will be spawned by a first round of “entrepreneur- in-residence” agreements initiated earlier this year at three of the labs, the department in November invited venture capital firms to bid for the opportunity to place an EIR in five others. The winning firms will hire an entrepreneur to work at one of the labs for up to a year, looking for renewable energy and energy-saving technologies that are ripe to spin off into commercial businesses.

“The EIR program is fundamentally changing the way we conduct business by helping our innovations reach the marketplace much faster,” Energy Secretary Samuel Bodman said in a statement. Although the EIR has been under way since spring at Sandia and Oak Ridge national laboratories and the National Renewable Energy Laboratory (NREL), a DOE official says it’s too soon to tell if the program has worked as planned. Rather, says the official, who

asked not to be identified, the agency thought that a larger sample of labs was needed to adequately judge how well the program will work. Participating venture capital firms say they have made good progress in narrowing down the hundreds of lab inventions to a few spinoff candidates. Still, the process has taken longer than DOE had anticipated when the program got under way. It was expected then that entrepreneurs would need just a few months to find a technology and get the commercialization process going. That pace would have allowed multiple entrepreneurs, and multiple technologies, to leave the labs during the year-long contract.

According to DOE’s 19 November program announcement, the next batch of EIRs will be taking up residence at Argonne, Brookhaven, Lawrence Livermore, Lawrence Berkeley, and Pacific Northwest national laboratories. For the new round, DOE is offering $50 000 to each entrepreneur to help defray salary and other expenses, and the awardees must at least match that amount. DOE’s share is only half the $100 000 the agency agreed to pay each
