He knew he wanted to study physics, but it wasn’t

Analyzing characteristics of fine particles in the air from space

It is well known that fine particulates in the air are associated with cardiovascular disease, respiratory diseases and cancer. What are not yet known are the different types of pollution that contribute to this fine particulate matter and which are most harmful to human health. Randall Martin, professor of energy, environmental and chemical engineering at

Weisensee to develop heat transfer switch for NASA

Weisensee Patricia Weisensee, assistant professor of mechanical engineering and materials science at the McKelvey School of Engineering at Washington University in St. Louis, plans to develop a liquid-metal-based heat switch that automatically turns on or off based on the external temperature with a three-year, $600,000 early-career award from NASA. The award is given annually to

Making atmospheric chemistry modeling more accessible

Global modeling of the atmosphere’s chemistry requires immense computational resources to study how particles form and are processed. A team of researchers, led by Randall Martin at Washington University in St. Louis, plans to improve a high-performance model so that it is more accessible and easier to use by researchers worldwide. Martin, a professor of

A closer look at the most distant object ever explored

In the May 17 issue of the journal Science, NASA’s New Horizons mission team published the first comprehensive profile of the farthest world ever explored: the Kuiper belt object 2014 MU69, nicknamed Ultima Thule, which is 4 billion miles from Earth. William B. McKinnon, New Horizons co-investigator, is professor of earth and planetary sciences in
