Researchers at the California Institute of Technology (Caltech) and NASA's Jet Propulsion Laboratory (JPL) have developed a new type of amplifier for boosting electrical signals. The device can be used for everything from studying stars, galaxies, and black holes to exploring the quantum world and developing quantum computers.

Using computer simulations, Caltech researchers have determined that if the interior of a dying star is spinning rapidly just before it explodes in a magnificent supernova, two different types of signals emanating from that stellar core will oscillate together at the same frequency. This could be a piece of "smoking-gun evidence" that would lead to a better understanding of supernovae.

Caltech chemists in the lab of Nobel laureate Bob Grubbs have developed a new class of catalysts that will increase the range of chemicals—from pharmaceuticals, insect pheromones, and perfume musks to advanced plastics—that can be synthesized using environmentally friendly methods.

NASA's NuSTAR space telescope has taken its first image, snapping a shot of the high-energy X rays from a black hole in the constellation Cygnus. NuSTAR—short for Nuclear Spectroscopic Telescope Array—was launched on June 13, and is the first telescope that can focus high-energy X rays. It will explore black holes, the dense remnants of dead stars, energetic cosmic explosions, and even our very own sun.

Caltech researchers have been able, for the first time, to watch viruses infecting individual bacteria by transferring their DNA, and to measure the rate at which that transfer occurs. Shedding light on the early stages of infection by this type of virus—a bacteriophage—the scientists have determined that it is the cells targeted for infection, rather than the amount of genetic material within the viruses themselves, that dictate how quickly the bacteriophage's DNA is transferred.

Imagine if doctors could perform surgery without ever having to cut through your skin. Or if they could diagnose cancer by seeing tumors inside the body with a procedure that is as simple as an ultrasound. Thanks to a technique developed by engineers at the California Institute of Technology (Caltech), all of that may be possible in the not-so-distant future.

In 1969, an exploding fireball tore through the sky over Mexico, scattering thousands of pieces of meteorite across the state of Chihuahua. More than 40 years later, the Allende meteorite is still serving the scientific community as a rich source of information about the early stages of our solar system's evolution. Recently, scientists from the California Institute of Technology (Caltech) discovered a new mineral embedded in the space rock—one they believe to be among the oldest minerals formed in the solar system.
