Would a deep-Earth water cycle change our understanding of planetary evolution? Washington DC (SPX) Dec 19, 2019
Every school child learns about the water cycle - evaporation, condensation, precipitation, and collection. But what if there were a deep Earth component of this process happening on geologic timescales that makes our planet ideal for sustaining life as we know it?

Creating a nanoscale on-off switch for heat Pittsburgh PA (SPX) Dec 19, 2019
Polymers are used to develop various materials, such as plastics, nylons, and rubbers. In their most basic form, they are made up of many of identical molecules joined together over and over, like a chain. If you engineer molecules to join together in specific ways, you can control the characteristics of the resulting polymer.
Using this method, Sheng Shen, an associate professor of mechan ... more
