Engineers find better way to detect nanoparticles

An engineering team at Washington University in St. Louis has made major strides recently in the study and manipulation of light. The team’s most recent discovery of the sensing capability of microresonators could have impacts in the creation of biomedical devices, electronics and biohazard detection devices.

Bar talk

Co-hosted by Elizabeth Haswell, associate professor of biology in Arts & Sciences at Washington University in St. Louis, Taproot is a new podcast that takes listeners behind the the curtain to reveal what it was really like to do the work so opaquely described in journal articles.

Neurogenetics for all

Sophisticated techniques for testing hypotheses about the brain by activating and silencing genes are currently available for only a handful of model organisms. Scientists at Washington University in St. Louis are working on a simplified toolkit that will allow scientists who study animal behavior to manipulate the genomes of many other animals with the hope of accelerating progress in our understanding of the brain.

Glass is weirder than you think

Changes in a liquid as it becomes a glass are related to repulsion between its atoms as they are crowded together. Although scientists have long believed the poorly understood glass transition must have atomic underpinnings, this is the first time they have been demonstrated experimentally.

Keep your distance

Why does biodiversity grade from exuberance at the equator through moderation at mid-latitudes toward monotony at higher ones? Data from an international network of long-term forest dynamics research sites is finally providing an answer.

Engineers examine chemo-mechanics of heart defect

Elastin and collagen serve as the body’s building blocks. Any genetic mutation short-circuiting their function can have a devastating, and often lethal, health impact. For the first time, new research led by engineers at Washington University in St. Louis takes a closer look at both genetic and mechanical attributes, to better understand a disorder that affects how elastin and collagen function.
