Chemists at Caltech and the Lawrence Berkeley National Laboratory believe they can now explain one of the remaining mysteries of photosynthesis, the chemical process by which plants convert sunlight into usable energy and generate the oxygen that we breathe.

Engineers at the California Institute of Technology (Caltech), working with a collaborator from the Jerusalem-based company LeukoDx, have developed a portable device to count white blood cells that needs less than a pinprick's worth of blood and takes just minutes to run.

Although Keith Matthews was about to make history, he went about his tasks like any others. It was the night of March 16, 1993, nearly 14,000 feet above sea level on Mauna Kea in Hawaii, and he had just installed the first instrument on the brand-new 10-meter telescope at W. M. Keck Observatory. Matthews, who built the instrument—a near-infrared camera, abbreviated NIRC—was set to make the first scientific observations using the newly crowned Biggest Telescope in the World.

PASADENA, Calif.—Galaxies have been experiencing vigorous bursts of star formation from much earlier in cosmic history than previously thought, according to new observations by a Caltech-led team.
These so-called starburst galaxies produce stars at a prodigious rate—creating the equivalent of a thousand new suns per year. Now the astronomers have found starbursts that were churning out stars when the universe was just a billion years old. Previously, astronomers didn't know whether galaxies could form stars at such high rates so early in time.

PASADENA, Calif.—Thanks to a new high-tech gadget, astronomers have observed four planets orbiting a star relatively close to the sun in unprecedented detail, revealing the roughly ten-Jupiter-mass planets to be among the most exotic ones known.
The team, which includes several researchers from the California Institute of Technology (Caltech), describes its findings in a paper accepted for publication by the Astrophysical Journal.

Imagine that the chips in your smart phone or computer could repair and defend themselves on the fly, recovering in microseconds from problems ranging from less-than-ideal battery power to total transistor failure. It might sound like the stuff of science fiction, but a team of Caltech engineers, for the first time ever, has developed just such self-healing integrated chips.

If you could lick the surface of Jupiter's icy moon Europa, you would actually be sampling a bit of the ocean beneath. So says Mike Brown, an astronomer at Caltech. Brown and Kevin Hand from the Jet Propulsion Laboratory (JPL) have found the strongest evidence yet that water from the vast liquid ocean beneath Europa's frozen exterior actually makes its way to the surface.

Laying the groundwork for an on-chip optical quantum network, a team of researchers, including Andrei Faraon from the California Institute of Technology (Caltech), has shown that defects in diamond can be used as quantum building blocks that interact with one another via photons, the basic units of light.
