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.

Mantis shrimp, aggressive, predatory sea crustaceans, have among the most sophisticated vision of all animals. A group of researchers, including Viktor Gruev, PhD, want to recreate that vision to make a specialized camera that could bring more precision to biomedical imaging and weapon targeting in defense.

Detecting whether a patient will have acute kidney injury could become as simple as dipping a paper test strip printed with gold nanorods into a urine sample, a team of Washington University in St. Louis researchers has found.

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.

Excitement is building at WUSTL in anticipation of hosting the 2013 Clinton Global Initiative University (CGI U) next April. CGI U application workshops are under way and two graduate biology students are seeing their hard work from CGI U 2012 come to life through their initiativecalled ProSPER. The next CGI U application workshops are Monday and Tuesday, Nov. 12 and 13.

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. 

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.

Sunscreen contains nanoparticles to protect our skin by reflecting hazardous ultraviolet radiation from the sun. But what happens to those nanoparticles when you wash the sunscreen away? Young-Shin Jun, PhD, has received a three-year, $382,000 grant from the National Science Foundation to determine the physical and chemical evolution of environmental and engineered nanoparticles in natural and engineered aquatic systems, such as wastewater treatment plants.

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.
