New Class of Catalysts Opens Up Green Route to a Range of Chemical Products

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.

Caltech at the LHC

Maria Spiropulu and Harvey Newman, both professors of physics at Caltech, lead the Caltech team of 40 physicists, students, and engineers that is part of the Compact Muon Solenoid (CMS) collaboration at the Large Hadron Collider (LHC) in Geneva, Switzerland.

Physicists Discover a New Particle that May Be the Higgs Boson

Physicists at the Large Hadron Collider (LHC) in Geneva, Switzerland, have discovered a new particle that may be the long-sought Higgs boson, the fundamental particle that is thought to endow elementary particles with mass.

X-ray Telescope Takes First Image

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.

Zooming in on Single Cells

Last fall, assistant professor of chemistry Long Cai received a New Innovator Award from the National Institutes of Health (NIH)—funding meant to both stimulate highly innovative research and support promising new investigators. Now, just nine months later, Cai has published the first results of his supported research.

The Physics of Going Viral

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.

Seeing Inside Tissue

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.

Caltech Scientists Find New Primitive Mineral in Meteorite

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.

Caltech Chemical Engineers Devise New Way to Split Water

Providing a possible new route to hydrogen-gas production, researchers at Caltech have devised a series of chemical reactions that allows them, for the first time, to split water in a nontoxic, noncorrosive way, at relatively low temperatures.

 

Hands-On Research

A nuzzle of the neck, a stroke of the wrist, a brush of the knee—these caresses often signal a loving touch, but can also feel highly aversive, depending on who is delivering the touch, and to whom. Interested in how the brain makes connections between touch and emotion, neuroscientists at the California Institute of Technology (Caltech) have discovered that the association begins in the brain's primary somatosensory cortex, a region that, until now, was thought only to respond to basic touch, not to its emotional quality.
