I. Science and Technology Briefs

Mass Producing One of a Kinds
Allan Shiers is a craftsman of a rare sort. At his studio in Llandysul, Wales, he hand makes Celtic and concert harps. So slow and intricate are the traditional woodworking techniques he employs-he makes each piece by hand-Shiers can produce only one of each type of harp a year. Now the Manufacturing Engineering Centre at Cardiff University is helping him revolutionize his craft by ushering in mass production. The result is a new company, Telynau Teifi, which can churn out 125 Celtic harps and 15 concert harps a year, at reduced cost, and without losing the precision quality that comes from handcrafting. According to MEC, senior research associate Andrew Thomas, Celtic harps are smaller and lighter than concert harps and are composed of just 250 parts. Concert harps, which are about 5 feet tall, have more strings, require foot pedals connected to a series of levers to control string pitch, and have about 2,000 parts. The MEC engineers devised computer-controlled routers and lathes that can accurately and quickly manufacture intricately shaped parts. Moreover, they changed some of the woods used and redesigned some structural elements so that they are thinner and less bulky. "This means that we have a clearer, more responsive sound since many of the sound-deadening issues have been removed," Thomas says. "We did not want to change the traditional feel of the harp. We just wanted to re-engineer it to make it lighter and more responsive." Shiers's handmade Celtic harps retailed for around $5,000, his concert harps, for around $20,000. The new versions will sell for around $2,800 and $14,000, respectively. And Thomas says ongoing manufacturing refinements will bring those costs down even further. That should strike a heavenly chord with the world's harpists.

Not Just for Bones Anymore
X-rays are particularly helpful in giving physicians pictures of diseased or damaged bones. But they're of less use for problems of the flesh. Because their beams pass so easily through soft tissue, the resulting images are vague. But researchers at the Brookhaven National Laboratory-home of the National Synchrotron Light Source (NSLS), a powerful particle accelerator-and Chicago's Rush Medical College, have teamed to develop a new technique called Diffraction Enhanced Imaging (DEI). It's an X-ray that provides images of soft tissue as detailed as those produced by ultrasound or magnetic resonance imaging. The technique makes use of intense X-ray beams generated by the NSLS. Those rays are thousands of times brighter than the ones created by conventional X-ray tubes. Although the beams are more intense, they're of a much lower dose than conventional X-rays.

Here's how the technique works: The powerful beams are shot through the specimen being analyzed. As they exit, they bend and scatter to varying degrees, depending on the composition of the tissue they're passing through. But before refracted rays hit the image detector, they're bounced off a silicon crystal, which allows the detector to measure the differing intensities of the bent beams. The result is very detailed images of not only bone, but tendons, ligaments, blood vessels, fat, and skin. And it takes only a few seconds to achieve those pictures.

Of course, synchrotron light sources are not readily available. But Zhong Zhong, a Brookhaven physicist, says the technique's "principle applies, no matter what source you use"-including a conventional X-ray tube. But using a conventional X-ray tube, at a lower dose, means it would take hours, rather than seconds, to get a detailed image. There are, however, ways to upgrade standard machines and make them more powerful, Zhong says, and developers are working to produce a portable prototype. He estimates that clinical application of DEI technology is perhaps 10 years off. But, eventually, it could prove particularly useful in the detection of breast cancer, lung cancer, and osteoarthritis.

II. Congressional Hotline

Engineering Mentors Receive Presidential Award
Last month President Bush named nine individuals and eight institutions winners of the 2003 Presidential Award for Excellence in Science, Mathematics, and Engineering Mentoring (PAESMEM). The award, which includes a $10,000 grant for continued mentoring work, is administered by the National Science Foundation on behalf of the White House.

The press release announcing the winners says the award recognizes "people and institutions that have provided broad opportunities for participation by women, minorities, and people with disabilities in science, mathematics, and engineering in elementary, secondary, undergraduate, and graduate education." Among the winners for engineering, individuals were highlighted for their approaches to encouraging females and minorities to pursue engineering careers and for creating a supportive environment for these students. A University of South Florida professor, for example, was presented the award because of his efforts in a program called "YES-We Care," which interests, influences, and prepares minority pre-college students for success as engineering students. The institutional winners-such as the National Society of Black Engineers and the Women in Engineering program at Pennsylvania State University-all had in common a commitment to promoting science, mathematics, and engineering education for under-represented minorities of all ages.

FY 2006 Budget to Include Domestic Program Cuts
The White House issued a memo last week with guidelines on the FY 2006 federal budget, saying that the administration's budget request, should George W. Bush win a second term, will likely include spending cuts for virtually all agencies in charge of domestic programs, including education, homeland security, and others that the president has supported during his re-election campaign. Departments slated for cuts, according to the memo that was obtained by the Washington Post, include the Education Department, Department of Veterans Affairs, the National Science Foundation, and the Environmental Protection Agency. The memo warns agencies to prepare to make cuts for most domestic programs when they prepare their initial FY 2006 proposals and notes that if agencies want additional funding for a particular program, they must find the money internally by cutting their budget elsewhere.

Democrats criticized the proposed funding cuts. "Despite [administration] denials, this memorandum confirms what we suspected all along," said Thomas S. Kahn, minority staff director on the House Budget Committee. "Next February, the administration plans to propose spending cuts in key government services to pay for oversized tax cuts."

Crash Course in Safety
A new, state-of-the-art automotive crash-test facility is expected to open in 2005 at the George Washington University's (GW) Ashburn, Va., campus. The $16 million center will be the world's first university-based full-scale indoor crash test lab. It will also be part of an 80,000-square-foot Transportation Research Institute at the university's Virginia campus, operated by the National Crash Analysis Center (NCAC). "The new facility will allow us to run the high-quality tests with sophisticated instrumentation that is required for advanced safety research but without enormous costs," says Nabih E. Bedewi, a professor of engineering and applied science at GW, and the director of NCAC. The new facility will rely heavily on computer simulations. The center conducts engineering research in three main areas: vehicle safety and biomechanics; highway and infrastructure safety; and advanced computer modeling and simulation. It pioneered research that led to the phasing out of two-point seat belts, which were found to leave wearers prone to liver lacerations even in minor crashes. The center has also designed improved highway safety barriers that have cut injury and fatality rates in auto wrecks. Currently, it's working with several government agencies to improve the design of security barriers outside important buildings.

Where the Men Aren't
AUSTRALIA - As in the United States, there are more women in college in Australia than men. Overall, there are 75,000 more females among the 829,571 students enrolled in the nation's 41 universities-11 of which now have female vice-chancellors (the equivalent of college presidents in this country). Moreover, there are 80,000 more women than men with university degrees in the 25-34 age group. Of 145,000 students awarded degrees last year, 6 in 10 were female.

Women became a student majority 16 years ago. Now, female students dominate in almost every field except in engineering and information technology, where 70 percent of the students are males. Young women have been particularly attracted to medicine and law, along with agriculture, architecture, and business. The number of women in engineering has increased slightly.

Educators believe that programs aimed at girls espousing the benefits of a college education in grade school and high school are at least partly responsible for the increase. Now, says, Bob Birrell, a researcher at the Melbourne-based Monash University Center for Population and Urban Research, there's a need for similar programs directed at boys. But he admits that educators don't really know if efforts to persuade boys to aim higher than part-time courses and service industry jobs will actually work. Educators agree that it's just as important to have a male presence on campus as it was earlier to have a substantial female population.

Toy Story
By Pierre Home-Douglas

Leif Askeland remembers enjoying the movie Big, in which Tom Hanks plays a 13-year-old kid reborn in the body of an adult and becomes a major creative talent at Macmillan Toys. Still, he found the 1988 hit a little far-fetched-and not just because he doesn't believe in reincarnation. "The toy industry is a lot different than what most people think," says the soft-spoken 45-year-old. "We don't sit around and play with toys all day. Actually, we take them very seriously."

Pursuing New Paths
By Bethany Halford

Chemical Engineering has a PR problem. When it comes to attracting new students, enrollment in chemical engineering lags behind the other three disciplines-civil, electrical, and mechanical-in engineering's "big four." This is odd because with just a bachelor's degree, an inexperienced chemical engineer fresh out of college can earn over $50,000 annually, more than B.S. graduates in any other engineering field. And chemical engineers have played integral roles in shaping the technology of the modern world-developing products from plastics to penicillin to polyester. But in the minds of bright engineering students eager to make their mark on the world, the word "chemical" tends to conjure images of massive, smoke-belching factories and oil refineries rather than the robust field. When it comes to attracting new students, chemical engineering programs lag behind the other three disciplines-civil, electrical, and mechanical-in engineering's "big four."
