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.

In September, the NASA/JPL Cassini mission began the last two years of the Solstice Mission. We recently spoke with JPL director Charles Elachi to gain his unique perspective on Cassini's achievements—and what will come next.

Caltech geochemist Clair Patterson (1922–1995) helped galvanize the environmental movement 50 years ago when he announced that highly toxic lead could be found essentially everywhere on Earth, including in our own bodies—and that very little of it was due to natural causes.

Feynman Teaching Award winner Mike Brown ventures into new fields of instruction: the Massive Open Online Course, or MOOC, and the "flipped" classroom, which inverts the traditional arrangement of listening to lectures in class and doing assignments at home.
