Caltech and JPL researchers identify a process involving UV light from the sun that helps explain how a moderately dense martian atmosphere 3.8 billion years ago could have evolved into the current thin one without invoking a missing carbon reservoir.
Three years ago this week, the U.S. Supreme Court ruled unconstitutional a key provision of the Voting Rights Act (VRA), which was enacted in 1965 and extended four times since then by Congress. The decision, says Kousser, was wrong.

Clinical trials are used to test the latest drugs and treatments, but few of these trials track how human behavior influences the effectiveness of these therapeutics. In a new study, Caltech's Erik Snowberg suggests an approach to tracking such influences.
Known as the Combined Array for Research in Millimeter-wave Astronomy, or CARMA, the telescopes tucked away on a remote, high-altitude site in the Inyo Mountains formed one of the most powerful millimeter interferometers in the world.
Taking advantage of airborne radar tools, Caltech researchers provide two possible explanations for a series of unusual earthquakes seen in Iceland during a period of volcanic activity that started in August last year.
