Eighteen Washington University in St. Louis undergraduate students will have the opportunity to spend their spring break in a unique way — a 10-day immersion in various aspects of the Israeli economy, from innovation to government to high-tech start-ups.

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.

The annual African Film Festival at Washington University in St. Louis begins Friday, March 23. Over the course of three days, eight different films will showcase the African continent and its people. During a youth matinee, award-winning director, writer and animator Cilia Sawadogo will answer audience questions about her film.

Just in time for spring baseball, the Assembly Series at Washington University in St. Louis presents its version of a doubleheader: back-to-back lectures in one day by prominent speakers. On Tuesday, March 5, Science historian Susan Lindee, PhD, will speak at 4 p.m. in McDonnell Hall on the evolution of a treatment for cystic fibrosis, once a fatal disease of children. Best-selling author, law professor and “Tiger Mom” Amy Chua, JD, follows at 5 p.m. in Graham Chapel. Both lectures are free and open to the public.

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.

Vu Nguyen, who joined the Department of Music in Arts & Sciences last fall as director of winds, will conduct the WUSTL Wind Ensemble in a free concert at 7:30 p.m. Tuesday, Feb. 28, at the 560 Music Center.

Humans today struggle with environmental problems such as a depleted ozone layer and global warming — influences of humans on the environment that put our own existence at risk. But humans altering their environment with disastrous results is nothing new. Just ask archeologist T.R. Kidder, PhD, professor of anthropology in Arts & Sciences, who has spent the past four summers excavating the Han Dynasty village of Sanyangzhuang.

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.
