David Peters, PhD, the McDonnell Douglas Professor of Engineering in the School of Engineering & Applied Science at Washington University in St. Louis, has received the Reed Aeronautics Award for 2011 from the American Institute of Aeronautics and Astronautics. The Reed Award is the highest award an individual can receive for achievements in the field of aeronautical science and engineering.

Collaborating with researchers in NASA, Daren Chen, PhD, has used the miniature particle size that he had developed as a part of a special smoke detector that was tested by the National Institute of Standards and Testing on more than 200 different kinds of fires and found to be 100 percent accurate. “I’m very interested in making this better sensor cheap enough to eventually allow networks in large buildings and ultimately save human lives,” Chen says.

Mark Alford, PhD, professor of physics in Arts & Sciences at Washington University in St. Louis, participated Jan. 29 in a roundtable discussion in New York about the quantum mind theory of consciousness. Quantum mind is a fashionable theory originally proposed by physicist Roger Penrose that grounds perception in the periodic collapse of quantum entangled electrons in our brain. Alford, who studies phenomenon that can only be explained by quantum mechanics nonetheless played the role of the skeptic in the discussion, which was videotaped and posted on the web.

Washington University engineering students Nalin Katta and Matthew MacEwan, who also is a School of Medicine student, won the Olin Cup business plan competition Feb. 3 and $50,000 in seed investment for an invention that can replace the protective covering of the brain. With 49 entrants, this year’s competition was the largest group of ventures yet.

Crop yields from India’s first genetically modified crop may have been overemphasized, as modest rises in crop yields may come at the expense of sustainable farm management, says a new study by a Washington University in St. Louis anthropologist.

In the Jan. 14 issue of Science, Washington University in St. Louis biologist Sarah C.R. Elgin, PhD, and 12 other biomedical research scientists recommend seven steps that universities can take to support the teacher-scientist, ranging in difficulty from educating faculty about research on learning or creating teaching discussion groups to creating (monetary) awards and named professorships for outstanding teachers and requiring excellence in teaching for promotion.

Who knew? The chance discovery that spikes in seismometer noise recorded in Africa corresponded with soccer matches has led to the discovery that there’s a lot more buried in the noise, including a signal from the famous storms of the Southern Atlantic Ocean, the bane of ships of sail.

A Washington University in St. Louis team is participating in the modENCODE project, a massive ongoing effort to map all the elements in model organisms that affect whether genes are silenced or expressed. The work supports the more complex ENCODE project, which is tasked to map the same elements in the human genome. While the genome is the same in every cell, each cell type expresses a different set of genes. In people, moreover, roughly 95 percent of the genome is silenced. Together the projects will “put flesh on the bones” of the Human Genome Project, says team leader Sarah C.R. Elgin.

Using a sophisticated version of the stroboscopic photography a pioneering photographer used in 1877 to prove that a horse takes all four hooves off the ground when it gallops, Michael L. Gross, PhD, professor of chemistry in Arts & Sciences and of medicine and immunology in the School of Medicine, catches proteins in the act of folding.

Three Washington University faculty — two from the School of Medicine and one from Arts & Sciences — have been named fellows of the American Association for the Advancement of Science, the world’s largest general scientific society.
