Caltech Scientists Create Tiny Photon Clock

In a new development that could be useful for future electronic devices, applied physicists at the California Institute of Technology have created a tiny disk that vibrates steadily like a tuning fork while it is pumped with light. This is the first micro-mechanical device that has been operated at a steady frequency by the action of photons alone.

KamLAND Detector Provides New Way to Study Heat from Radioactive Materials Within Earth

Much of the heat within our planet is caused by the radioactive decay of the elements uranium and thorium. Now, an international team of particle physicists using a special detector in Japan has demonstrated a novel method of measuring that radioactive heat.

Researchers devise plasma experiment that shows how astrophysical jets are formed

Applied physicists at the California Institute of Technology have devised a plasma experiment that shows how huge long, thin jets of material shoot out from exotic astrophysical objects such as young stars, black holes, and galactic nuclei.

Andromeda Galaxy Three Times Bigger in Diameter Than Previously Thought

Scott Chapman, from the California Institute of Technology, and Rodrigo Ibata, from the Observatoire Astronomique de Strasbourg in France, have led a team of astronomers in a project to map out the detailed motions of stars in the outskirts of the Andromeda galaxy. Their recent observations with the Keck telescopes show that the tenuous sprinkle of stars extending outward from the galaxy are actually part of the main disk itself.

Four from Caltech Named to National Academy of Sciences

Three members at the California Institute of Technology faculty and one former faculty who is now a visiting associate are among the 72 new members and 18 foreign associates being named to the National Academy of Sciences today. The election was announced during the 142nd annual meeting of the Academy in Washington, D.C.

Five from Caltech Faculty Elected to American Academy of Arts and Sciences

Five faculty members at the California Institute of Technology are among this year's newly elected fellows of the American Academy of Arts and Sciences. They join 191 other Americans and 17 foreign honorees as the 225th class of fellows of the prestigious institution that was cofounded in 1780 by John Adams.

Caltech Physicist Kip ThorneWins 2005 Common Wealth Award

Kip Thorne, a physicist who is famed for his work on the cosmic consequences of relativity, is one of five winners of the 2005 Common Wealth Award.

Caltech Physics Team Invents DeviceFor Weighing Individual Molecules

Physicists at the California Institute of Technology have created the first nanodevices capable of weighing individual biological molecules. This technology may lead to new forms of molecular identification that are cheaper and faster than existing methods, as well as revolutionary new instruments for proteomics.

Hard X-Ray telescope up for final NASA review; project will be led by Caltech's Fiona Harrison

If all goes well with a technical study approved by NASA for this year, an innovative telescope should be orbiting Earth by the end of the decade and taking the first focused high-energy X-ray pictures of matter falling into black holes and shooting out of exploding stars. Not only will the telescope be 1,000 times more capable of finding new black holes than anything previously launched into space, but it will also give us an unprecedented look at the origins of the heavy elements we're all made of.

Retired Caltech Physicist Robert Walker Dies; Worked on Manhattan Project as Grad Student

Robert Walker, a retired physics professor at the California Institute of Technology, died January 4 in New Mexico. A graduate student who worked on the Manhattan Project during World War II, he was 85 years old at the time of his death.
