John O. Dabiri, a fluid-dynamics expert at Caltech whose studies of schooling fish have inspired new ideas for wind farming, was named a MacArthur Fellow, and awarded a five-year, $500,000 "no strings attached" grant. Each year, the John D. and Catherine T. MacArthur Foundation awards the unrestricted fellowships to individuals who show "exceptional creativity in their work and the prospect for still more in the future," according to the Foundation's website.

Using a diamond-anvil cell to recreate the high pressures deep within the earth, researchers at the California Institute of Technology (Caltech) have found unusual properties in an iron-rich magnesium- and iron-oxide mineral that may explain the existence of several ultra-low velocity zones (ULVZs) at the core-mantle boundary. A paper about their findings was published in a recent issue of Geophysical Research Letters (GRL).

Computational scientists and geophysicists at the University of Texas at Austin and Caltech have developed new computer algorithms that for the first time allow for the simultaneous modeling of the earth's mantle flow, large-scale tectonic plate motions, and the behavior of individual fault zones, to produce an unprecedented view of plate tectonics and the forces that drive it.

Ralph W. Kavanagh, professor of physics, emeritus, at the California Institute of Technology (Caltech) passed away August 16 in Pasadena, California. He was 86.

Two scientists from Caltech have been recognized by the National Institutes of Health for their innovative and high-impact biomedical research programs. Michael Roukes, professor of physics, applied physics, and bioengineering, and co-director of the Kavli Nanoscience Institute, and Pamela Bjorkman, Caltech's Max Delbrück Professor of Biology and a Howard Hughes Medical Institute investigator, now join the 81 Pioneers who have been selected since the program's inception in 2004.

The National Research Council (NRC) has strongly recommended the Laser Interferometer Space Antenna (LISA) as one of NASA's next two major space missions, to start in 2016 in collaboration with the European Space Agency (ESA). LISA will study the universe in a manner different from any other space observatory, by observing gravitational waves. The recommendation was announced August 13 in a press conference at the Keck Center of the National Academies in Washington, D.C.

In an announcement August 13, the National Research Council recommended three space- and ground-based astronomy and astrophysics projects with potential major roles for researchers at Caltech: CCAT, a giant submillimeter telescope that will help unravel the origins of stars, planets, and galaxies; LISA, designed to detect gravitational waves; and the development of a Giant Segmented Mirrored Telescope—the Thirty Meter Telescope being one of two such telescopes under development.

Hundreds of extrasolar planets have been found, most solitary worlds orbiting their parent star in seeming isolation. Further observation has revealed that planets come in bunches. Most systems contain planets orbiting too far from one another to feel each other's gravity. In a handful of cases, planets have been found near enough to one another to interact gravitationally. Now, however, Caltech's John A. Johnson and his colleagues have found two systems with pairs of gas giant planets locked in an intimate orbital embrace.

Astronomers at Caltech and Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have discovered the first known case of a distant galaxy being magnified by a quasar acting as a gravitational lens. The discovery, based in part on observations done at the W. M. Keck Observatory on Hawaii's Mauna Kea, is being published July 16 in the journal Astronomy & Astrophysics.

The World Cup is in full swing, complete with an official new soccer ball named Jabulani, meaning "to celebrate" in Zulu. The players, however, aren't exactly celebrating. Instead, many of them are complaining that the ball's trajectory is too hard to predict. So what exactly is it about the new ball that's provoking all the controversy? To find out, Caltech engineers put an official Jabulani through its paces in the Lucas Adaptive Wall Wind Tunnel.
