ENROLLMENT LEVELS
Enrollment in computer science programs may have leveled off after the dot-com downturn, but that leveling happened only after the number of bachelor’s degree graduates hit a trough, reports Computerworld. In the latest statistics from the Computing Research Association ( www.cra.org), which follows year-over-year enrollment and graduate trends from 170 Ph.D.-granting institutions, only 8,021 students graduated with computer science degrees from these schools in the 2006–2007 academic year. By contrast, in 2003–2004—the high point of this decade— 14,185 students were awarded bachelor’s degrees in computer science. The sharp decline in graduates may be about to level off, according to CRA’s latest trend analysis. In the fall of 2006, new CS enrollments topped out at 7,840; new enrollments for fall 2007 were at 7,915. While it’s too early to declare a turnaround, CRA analysts say the students should be able to find job opportunities based on the last projections from the U.S. Bureau of Labor Statistics (see box on page 8).
NEW YORK’S GLOBAL LINKS
Bottom: Jeremy Levy
MIT researchers have been collecting the electronic communications of millions of New Yorkers since last January. The round-the-clock effort has nothing to do with national security or covert eavesdropping. Rather it is to build a census that shows, neighborhood by neighborhood, the phone and Internet links New Yorkers have to other cities across the planet and how these connections change over time. “Our cities and the globe are blanketed with flowing bits of digital data, and looking at this data, we’re able to better understand the physical world,” says Carlo Ratti, director of MIT’s SENSEable City Lab. The Associated Press reports that no information about individuals or actual conversations is being collected. AT&T gives MIT only aggregate data from its switches throughout the city. Researchers found New Yorkers who engage in global gab tend to be international business professionals or poor immigrants. Moreover, communication between
Manhattan and the world surges each morning after the New York Stock Exchange opens. The most-called city is London (8% of all overseas calls), followed by Santo Domingo (5%). Half of all calls from Manhattan are to Canada, Great Britain, the Dominican Republic, Germany, and Japan. Visualizations from the New York Talk Exchange ( sensible.mit.edu/nyte) project are now part of an exhibit at the Museum of Modern Art called “Design and the Elastic Mind,” which is open through May and examines how designers use technology in ways that change lives.
ETCH-A-CIRCUIT
Researchers have demonstrated a new technique inspired by the classic Etch-a-Sketch drawing toy that could be used to create rewritable logic circuits and denser computer memory. Technology Review reports that researchers, using an atomic force microscope
(AFM), were able to draw nano-size wires and dots that could be repeatedly erased and written. The researchers used an AFM tip like a pencil,
