Kunal Agrawal, PhD, assistant professor of computer science & engineering in the School of Engineering & Applied Science at Washington University in St. Louis, has won a prestigious Faculty Early Career Development Award from the National Science Foundation. The goal of Agrawal’s project, titled “Provably Good Concurrency Platforms for Streaming Applications,” is to design platforms that will allow programmers to easily write correct and efficient high-throughput parallel programs.

William F. Pickard of Washington Unviersity in St. Louis introduces the February 2012 special issue of the Proceedings of the IEEE by quoting the Bible: “The wind bloweth where it listeth.” That, in so many words, describes is the major technological problem with renewable sources of energy, such as solar and wind power. The special issue, which Pickard co-edited with Derek Abbott of the University of Adelaide, discusses several solutions to intermittency, as it is called, first among them massive energy storage.

Mathematician John E. McCarthy, PhD, was installed March 2 as the Spencer T. Olin Professor in Arts & Sciences in a ceremony in Holmes Lounge.  Following the formal installation and the presentation of the professorship medallion, McCarthy spoke on “Why Pure Mathematics Matters.”

Research by WUSTL anthropologist Crickette Sanz, PhD, and colleague David Morgan, PhD, has spurred the Republic of Congo to enlarge its Nouabalé-Ndoki National Park boundaries to include the Goualougo Triangle. The Goualougo Triangle is a remote, pristine forest that is home to at least 14 communities of “naïve” chimpanzees with little exposure to humans.

How is it that an insect can remake itself so completely that it appears to be a different creature altogether, not just once, but several times in its lifetime? Working with fruit flies, a team led by Ian and Dianne Duncan of Washington University in St. Louis found that genes whose expression is induced by pulses of steroid hormone are key to these transformations. A similar mechanism may underlie  puberty — the human analog of metamorphosis.

The prevailing model for planetary accretion assumes that the Solar System’s planets formed in an extremely hot, two-dimensional disk of gas and dust, post-dating the Sun. In the March issue of Planetary and Space Science, two scientists at Washington University in St. Louis propose a radically different model, in which collapse takes place in a cold, three-dimensional dust cloud.

Work at Washington University in St. Louis, just published in EcoHealth, shows that the ecology of fear, like other concepts from predator-prey theory, also extends to parasites. Raccoons and squirrels would give up food, the study demonstrated, if the area was infested with larval ticks. At some level, they are weighing the value of the abandoned food against the risk of being parasitized.

Liviu M. Mirica, PhD, assistant professor in the Department of Chemistry in Arts & Sciences at Washington University in St. Louis, has won a prestigious research fellowship from the Sloan Foundation. Mirica will use the funds to develop novel catalysts that will be able to efficiently convert the greenhouse gases methane (CH4) and carbon dioxide (CO2) into useful chemicals.

Last year, the National Collegiate Athletic Association required all aluminum bats used in college play to meet a new performance standard designed to limit the exit speed of the ball off the bat. This year, the National Federation of State High School Associations also has implemented the new standard. With spring training beginning at all levels this month, a WUSTL professor and WUSTL baseball coaches comment on the new bats and how they have affected play.

Kilian Q. Weinberger, assistant professor of computer science & engineering in the School of Engineering & Applied Science, has won a prestigious Faculty Early Career Development Award (CAREER award) from the National Science Foundation. Weinberger’s CAREER project, “New Directions for Metric Learning,” seeks to solve one of the fundamental problems of machine learning: how to compare individual texts, images or sounds.
