Caltech researchers devisenew microdevice for fluid analysis

Researchers at the California Institute of Technology announced today a new paradigm for large-scale integration of microfluidic devices. Using new techniques, they built chips with as many as 6,000 microvalves and up to 1,000 tiny individual chambers.

MacArthur Foundation certifies two Caltech professors as geniuses

Two members of the California Institute of Technology faculty have been named MacArthur Fellows, a prestigious honor bestowed each year on innovators in a variety of fields and commonly known as the "genius grants."

Charles Steidel, an astronomer, and Paul Wennberg, an atmospheric scientist, are two of the 24 MacArthur Fellows announced today by the John D. and Catherine T. MacArthur Foundation of Chicago. Each of the 24 recipients will receive a $500,000 "no strings attached" grant over the next five years.

Five Caltech Faculty Members Elected to Membership in the American Academy of Arts and Sciences

PASADENA, Calif. — The American Academy of Arts and Sciences has announced that five members of the Caltech faculty have been elected to membership in the academy for contributions to their respective scientific fields.

The Caltech faculty members who have been elected are Richard Andersen, Boswell Professor of Neuroscience; David Anderson, professor of biology and investigator with the Howard Hughes Medical Institute (HHMI); Ronald Drever, professor of physics, emeritus; Mary Kennedy, Davis Professor of Biology; and Mark Wise, McCone Professor of High Energy Physics.

Researchers make progress in understanding the basics of high-temperature superconductivity

High-temperature superconductors have long been the darlings of materials science because they can transfer electrical current with no resistance or heat loss. Already demonstrated in technologies such as magnetic sensors, magnetic resonance imaging (MRI), and microwave filters in cellular-phone base stations, superconductors are potentially one of the greatest technological triumphs of the modern world if they could just be made to operate more reliably at higher temperatures.

Researchers make plasma jets in the labthat closely resemble astrophysical jets

Astrophysical jets are one of the truly exotic sights in the universe. They are usually associated with accretion disks, which are disks of matter spiraling into a central massive object such as a star or a black hole. The jets are very narrow and shoot out along the disk axis for huge distances at incredibly high speeds.

Jets and accretion disks have been observed to accompany widely varying types of astrophysical objects, ranging from proto-star systems to binary stars to galactic nuclei.

Astronomers discover the strongest known magnet in the universe

Astrophysicists at the California Institute of Technology, using the Palomar 200-inch telescope, have uncovered evidence that a special type of pulsar has the strongest magnetic field in the universe.

Astrophysicists announce surprising discoveryof extremely rare molecule in interstellar space

A rare type of ammonia that includes three atoms of deuterium has been found in a molecular cloud about 1,000 light-years from Earth. The comparative ease of detecting the molecules means there are more of them than previously thought.

In a study appearing in the May 20 issue of the Astrophysical Journal Letters, an international team of astronomers reports on the contents of a molecular cloud in the direction of the constellation Perseus. The observations were done with the Caltech Submillimeter Observatory atop Mauna Kea in Hawaii.

Cosmic Background Imager uncoversfine details of early universe

Cosmologists from the California Institute of Technology using a special instrument high in the Chilean Andes have uncovered the finest detail seen so far in the cosmic microwave background radiation (CMB), which originates from the era just 300,000 years after the Big Bang.

Gamma-ray bursts are caused by explosive death of massive stars, new study reveals

In two papers appearing in an upcoming issue of the Astrophysical Journal, an international team of astrophysicists led by Shri Kulkarni of the California Institute of Technology reveals that new data show that supernovae are the source of gamma-ray bursts.

The new information was obtained from a gamma-ray burst that was detected in November and studied by the Hubble Space Telescope, the Australia Telescope Compact Array, the Anglo-Australian Telescope, and optical telescopes in Chile.

Researchers find evidence for mechanismthat creates near-Earth binary asteroids

About one in six of all near-Earth asteroids are binaries – in other words, two bodies that travel in close companionship as they orbit the sun.
