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.

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.

It is a harrowing prologue. Teenagers Brooke and Alex, high school sweethearts, panicked by an accidental pregnancy, rent a hotel room to deliver their stillborn child.
