A network of photonic units that can allow light to propagate in one direction while block the light flow in the opposite direction, like an all-optical analog of an electronic diode that allows current flow in one direction only. The photonic unit is composed of coupled photonic resonators with tailored loss/gain. (Credit: Micro/Nano Photonics Laboratory, Department of Electrical & Systems Engineering, Washington University)

Breaking the laws of science

Lan Yang, the Edwin H. & Florence G. Skinner Professor of Electrical and Systems Engineering in the School of Engineering & Applied Science, is the principal investigator of a four-year, $2 million grant from the National Science Foundation (NSF) in which she will oversee the takedown of two venerable physical laws: time-reversal symmetry and reciprocity.
Engineers at Washington University in St. Louis have found a new way to boost biofuel production in E. coli bacteria by altering its protein structure.

Engineering a better biofuel

The often-maligned E. coli bacteria has powerhouse potential: in the lab, it has the ability to crank out fuels, pharmaceuticals and other useful products at a rapid rate. A team from the School of Engineering & Applied Science at Washington University in St. Louis has discovered a new way to remove a major stumbling block in the process, and boost biofuel production from E. coli.

Taking out the trash

Autophagy (self eating) has long been considered a kind of indiscriminate Pac Man-like process of waste disposal. Now, scientists at Washington University have shown that apart from conditions of cell starvation, it is carefully regulated: both in plants and yeast — and most likely in people. The finding is relevant to aggregation-prone pathologies such as Alzheimer’s and Parkinson’s diseases.
New funding from the National Science Foundation and the Water Research Foundation will allow Washington University faculty members to study how to best control lead pipe corrosion.

Washington University researchers awarded $229K to study lead pipe corrosion

The National Science Foundation, along with the Water Research Foundation, has awarded a pair of Washington University in St. Louis researchers $229,000 in grants to study ways to best control lead pipe corrosion, which can poison drinking water. Daniel Giammar, the Walter E. Browne Professor of Environmental Engineering in the School of Engineering & Applied […]
