Researchers from Caltech and the Jet Propulsion Laboratory have provided a global observational study of the effect that changes in aerosol levels have on low-level marine clouds—the clouds that have the largest impact on the amount of incoming sunlight that Earth reflects back into space.

Caltech researchers stabilize microwave oscillators with optical frequencies from a silicon chip. The approach could ultimately replace more conventional methods that rely on crystal references—a technology in use since the 1920s.

Investment magnate Warren Buffett has famously suggested that investors should try to "be fearful when others are greedy and be greedy only when others are fearful."
That turns out to be excellent advice, according to the results of a new study by researchers at Caltech and Virginia Tech that looked at the brain activity and behavior of people trading in experimental markets where price bubbles formed. In such markets, where price far outpaces actual value, it appears that wise traders receive an early warning signal from their brains—a warning that makes them feel uncomfortable and urges them to sell, sell, sell.

In 1975, Kip Thorne (BS '62, and the Richard P. Feynman Professor of Theoretical Physics, Emeritus) and then-Caltech postdoctoral fellow Anna Żytkow sought the answer to an intriguing question: Would it be possible to have a star that had a neutron star as its core—that is, a hot, dense star composed entirely of neutrons within another more traditional star? Nearly 40 years later, astronomers believe they may have found such an object: a star labeled HV 2112 and located in the Small Magellanic Cloud, a dwarf galaxy that is a near neighbor of the Milky Way and visible to the naked eye. We recently sat down with Thorne to ask how it feels to have astronomers discover something whose existence he postulated decades before.
