Two Arts & Sciences seniors from Washington University in St. Louis were among 232 U.S. finalists for the prestigious Rhodes Scholarship. They are Madeleine Daepp, an enomics and mathematics student with an interest in agrigultural policy, and Jeremy Pivor, an environmental biology major with a passion for ocean conservation.

Two scientists at Washington University have developed a low-energy defibrillation scheme that significantly reduces the energy needed to re-establish a normal rhythm in the heart’s main chambers. They hope this electrotherapy will be much less painful than the existing electrotherapy, making treatment with a defibrillator much more acceptable to patients.

On November 8, 2012, Secretary of State Hillary Rodham Clinton announced the appointment of three new science envoys, including Barbara Schaal, the Mary-Dell Chilton Distinguished Professor of Biology in Arts & Sciences at Washington University in St. Louis. The science envoys travel in their capacity as private citizens and advise the White House, the U.S. Department of State, and the U.S. scientific community about the insights they gain from their travels and interactions.

Maria Zuber, a professor of geophysics at the Massachusetts Institute of Technology, will deliver the fifth annual Robert M. Walker Distinguished Lecture at 7 p.m. Wednesday, Nov. 14, in Room 100 in Whitaker Hall on the Danforth Campus. During the free, public lectures, she will discuss new information about water on the moon.

Some students enrolled in the Cognitive, Computational and Systems Neuroscience (CCSN) pathway, are sharing their love of science and improving communication skills through community outreach. CCSN is a specialization for graduate students in psychology, neuroscience and biomedical engineering. The students are coaching low-income area teens for an international competition called the Brain Bee, and participating in many events, including the Nov. 10 Amazing Brain Carnival held at the St. Louis Science Center. The free event introduces the public to brain science research in St. Louis. 

Investigators at Washington University and The Scripps Research Institute have announced the launch of a “Global Metabolomic Initiative” to facilitate meta-analyses on studies of the metabolism of bacteria, yeast, plants, animals and people. Although metabolomics has existed as a discipline for only a decade, it has already provided insights into many difficult-to-treat diseases, including chronic pain. Many more are expected to fall out of the meta-analyses.

Evolutionary biologist David C. Queller, PhD, was installed Oct. 16 as the Spencer T. Olin Professor of Biology in Arts & Sciences in a ceremony in Holmes Lounge.

It’s a big claim, but Washington University in St. Louis planetary scientist Frédéric Moynier says his group has discovered evidence that the Moon was born in a flaming blaze of glory when a body the size of Mars collided with the early Earth.

The International Center for Advanced Renewable Energy and Sustainability (I-CARES) will celebrate its inaugural I-CARES day Friday, Oct. 19. The celebration will feature a talk by Peter H. Raven, former president of the Missouri Botanical Garden, on climate change and its impact on biodiversity, and a presentation by T.R. Kidder, professor and chair of anthropology, on the idea that we may be entering a new geological era, called the Anthropocene, in which humans are the primary geological change agents. There also will be activities for students, including a QR-code scavenger hunt.​

Engineer Tae Seok Moon has made the most complex logic circuit ever assembled in a single bacterium. The logic circuit, in which genes and the molecules that turn the genes on or off function as logic gates, the simple devices that form the basis for electronic circuits, is one step in an effort to make programmable bacteria that can make biofuels, degrade pollutants, or attack cancer or infections.
