Measuring Earthquake Shaking
This summer, Caltech junior Kevin Li has been working with computational scientists and seismologists to refine the Community Seismic Network (CSN) by developing a machine-learning system that can accurately estimate the magnitude of an earthquake within seconds of its detection.
Programmed to Fold: RNA Origami
Researchers from Aarhus University in Denmark and Caltech have developed a new method for organizing molecules on the nanoscale. Inspired by techniques used for folding DNA origami—first invented by Paul Rothemund, a senior research associate in computation and neural systems in the Division of Engineering and Applied Science at Caltech—the team, which includes Rothemund, has fabricated complicated shapes from DNA's close chemical cousin, RNA.

NASA Satellite Sends Back Most Detailed CO2 View Ever
The first global maps that use data from the OCO-2 satellite were released this week, and measure atmospheric gas to a fraction of a percent. Paul Wennberg notes that this level of detail makes OCO-2 "one of the most challenging remote missions that has ever been attempted."

Voyager 1 Surfs a Cosmic Tsunami
The plasma wave instrument aboard Voyager I captured the sound of ionized gas vibrating in interstellar space three different times between November 2014 and December 2014. Physicist Ed Stone explains how the vibrations were caused by powerful blasts of solar particles, each resulting in a "cosmic tsunami."
