Science & Technology

Long before GPS satellites and NASA, Washington University astronomers played a central role in the scientific observation of total solar eclipses — including a search for the elusive planet Vulcan in the late 1800s.

Chancellor William Chauvenet nurtured Edward S. Holden’s interest in astronomy on the campus of Washington University, but Holden’s initial fascination with the field sprang from a series of circumstances associated with childhood tragedy.

Edward S. Holden’s 1883 expedition report to the National Academies was written with all due respect. However, a handwritten note, written in rhyme, from a crew member of the U.S.S. Hartford suggests the voyagers enjoyed lighter moments as well.

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.

A group of Washington University aerosol scientists, engineers and administrators traveled to Asia this summer to address some of the important problems related to energy, environment and health that we face today. Here, four engineering faculty share their takeaways.

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.

After conducting a new research approach using actual commutes, a group of engineers at Washington University in St. Louis discovered a simple shift in driving habits can help to reduce exposure to pollutants while out on the road.

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.

Behind the chubby cheeks and bright eyes of babies as young as 8 months lies the smoothly whirring mind of a social statistician, logging our every move and making odds on what a person is most likely to do next, suggests new research co-led by Washington University in St. Louis.

New Horizons team members just pulled off “eclipse” observations of a body at the far outer reaches of the solar system, showing August eclipse tourists how it’s done.
