Cherry A. Murray is named dean of SEAS

By Steve Bradt, FAS Communications / March 12, 2009

Cherry A. Murray, who has led some of the nation’s most brilliant scientists and engineers as an executive at Bell Laboratories and the Lawrence Livermore National Laboratory, has been appointed dean of Harvard University’s School of Engineering and Applied Sciences (SEAS), effective July 1, 2009. She will also become the John A. and Elizabeth S. Armstrong Professor of Engineering and Applied Sciences.

Small suds make a big splash at SEAS

By Grace Tiao, FAS Communications / June 12, 2008

The latest engineering feat to emerge from the laboratories at Harvard’s School of Engineering and Applied Sciences has been largely accomplished with the aid of kitchen mixers. Researchers have whipped up, for the first time, permanent nanoscale bubbles — bubbles that endure for more than a year — from batches of foam made from a mixture of glucose syrup, sucrose stearate, and water.

Undergrads create ‘dirt-powered’ light for Africa

By Michael Patrick Rutter, SEAS Communications / May 22, 2008

A team composed of Harvard students and alumni was among the winners of the World Bank’s Lighting Africa 2008 Development Marketplace competition, held in Accra, Ghana, from May 6 to 8, 2008. The team’s innovation, microbial fuel cell-based lighting systems suitable for sub-Saharan Africa, netted the Harvard group a $200,000 prize.

The beauty of computer science

By Grace Tiao, FAS Communications / April 3, 2008

As a sophomore at Harvard College in 1992, Salil Vadhan skeptically and rather grudgingly enrolled in an introductory departmental course that a friend had cajoled him into taking. The course was “Computer Science 121: Introduction to Formal Systems and Computation,” a class that he would revisit a little more than a decade later — as the professor.

Finding ingenious design in nature

By Grace Tiao, FAS Communications / February 21, 2008

“This,” Joanna Aizenberg says slyly, picking up a latticed tube from her desk in Pierce Hall, “is a glass house you can throw stones at.” The tube, tapered to a close at one end and festooned with a cluster of curious white fibers at the tip, resembles an upturned dog’s tail. It is, in fact, the skeleton of a deep-sea sponge, she reveals, made entirely out of a natural glass. The tube acts as a kind of high-rise apartment building for shrimp that live symbiotically in the sponge’s tissue.

Biohybrid of elastic film and muscle cells packs a punch

By Steve Bradt, FAS Communications / September 10, 2007

In an innovative marriage of living cells and a synthetic substrate, bioengineers at Harvard University have found that a rubberlike, elastic film coated with a single layer of cardiac muscle cells can semi-autonomously engage in lifelike gripping, pumping, walking, and swimming.

Undergrads to compete at Programming Contest

March 1, 2007

A group of Harvard undergraduates will travel to Tokyo to compete in the Association for Computing Machinery's 31st annual International Collegiate Programming Contest (ACM-ICPC) on March 12-16. More than 6,000 teams, representing 1,756 universities from around the globe, participated in the regional competitions last fall. The top 88 teams earned coveted spots on the 2007 ACM-ICPC World Finals roster. The Harvard team is one of only 20 U.S. teams scheduled to compete in the World Finals.

Medieval Islamic architecture presages 20th century mathematics

By David Baron, FAS Communications / March 1, 2007

Intricate decorative tilework found in medieval architecture across the Islamic world appears to exhibit advanced decagonal quasicrystal geometry - a concept discovered by Western mathematicians and physicists only in the 1970s and 1980s. If so, medieval Islamic application of this geometry would predate Western mastery by at least half a millennium.
