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.

Just as growth rings can offer insight into climate changes occurring during the lifespan of a tree, corals have much to tell about changes in the ocean. At Caltech, climate scientists Jess F. Adkins and Nivedita Thiagarajan use manned submersibles, like Alvin operated by the Woods Hole Oceanographic Institution, to dive thousands of meters below the surface to collect these specimens—and to shed new light on the connection between variance in carbon dioxide (CO2) levels in the deep ocean and historical glacial cycles.

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.

Evaluating another person's emotions based on facial expressions can sometimes be a complex task. As it turns out, this process isn't so easy for the brain to sort out either. Building on previous studies targeting the amygdala, a region in the brain known to be important for the processing of emotional reactions, a team of researchers from Caltech, Cedars-Sinai Medical Center, and Huntington Memorial Hospital in Pasadena, have found that some brain cells recognize emotions based on the viewer's preconceptions rather than the true emotion being expressed.

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.

Researchers at Caltech have applied a new imaging technique called four-dimensional (4D) electron microscopy to studying nanofluid dynamics. In a paper appearing in the June 27 issue of Science, Ahmed Zewail, the Linus Pauling Professor of Chemistry and professor of physics, and Ulrich Lorenz, a postdoctoral scholar in chemistry, describe how they visualized and monitored the flow of molten lead within a single zinc oxide nanotube in real time and space.

A team of scientists led by Caltech geochemist John M. Eiler has developed a new technique that can, for the first time, determine the temperature at which a natural methane sample formed.

If you're trying to outwit the competition, it might be better to have been born a chimpanzee, according to a study by researchers at Caltech, which found that chimps at the Kyoto University Primate Research Institute consistently outperform humans in simple contests drawn from game theory.
