Researchers from Caltech have isolated a very specific difference in how high-functioning people with autism think about other people, finding that—in actuality—they don’t tend to think about what others think of them at all.

For the first time, researchers at Caltech, in collaboration with a team from the University of Vienna, have managed to cool a miniature mechanical object to its lowest possible energy state using laser light. The achievement paves the way for the development of exquisitely sensitive detectors as well as for quantum experiments that scientists have long dreamed of conducting.

The cameras in our cell phones have dramatically changed the way we share the special moments in our lives, making photographs instantly available to friends and family. Now, the imaging sensor chips that form the heart of these built-in cameras are helping engineers at the California Institute of Technology (Caltech) transform the way cell cultures are imaged by serving as the platform for a "smart" petri dish.

Responding to faces is a critical tool for social interactions between humans. Without the ability to read faces and their expressions, it would be hard to tell friends from strangers upon first glance, let alone a sad person from a happy one. Now, neuroscientists from Caltech, with the help of collaborators at Huntington Memorial Hospital in Pasadena and Cedars-Sinai Medical Center in Los Angeles, have discovered a novel response to human faces by looking at recordings from brain cells in neurosurgical patients.

When making decisions based on multiple interdependent factors—such as what combination of stocks and bonds to invest in—humans look at how the factors correlate with each other, according to a new study by researchers from Caltech and University College London.

An international team led by the Jet Propulsion Laboratory has used radar sounding technology developed to explore the subsurface of Mars to create high-resolution maps of freshwater aquifers buried deep beneath a desert on Earth.

As we take in the world around us, learn, and form memories, the synapses between neurons in our brains are constantly being modified. Some get stronger, while others are allowed to shrink or get weaker. The network of enzyme-regulated chemical reactions that control these modifications is complex, to say the least. Now Mary Kennedy, the Allen and Lenabelle Davis Professor of Biology at Caltech, has come up with a way to tease apart the elusive details of that network.

After a successful lift off on Saturday, September 10, NASA's twin Gravity Recovery and Interior Laboratory (GRAIL) spacecrafts are headed toward the moon to study its gravity field. The two solar-paneled spacecrafts are expected to reach lunar orbit at the end of the year.

Some people feel compelled to pet every furry animal they see on the street, while others jump at the mere sight of a shark or snake on the television screen. No matter what your response is to animals, it may be thanks to a specific part of your brain that is hardwired to rapidly detect creatures of the nonhuman kind. In fact, researchers from Caltech and UCLA report that neurons throughout the amygdala—a center in the brain known for processing emotional reactions—respond preferentially to images of animals.

Caltech researchers have obtained the first high-resolution, three-dimensional images of a cell with a nucleus undergoing cell division. The observations, made using a powerful imaging technique in combination with a new method for slicing cell samples, indicate that one of the characteristic steps of mitosis is significantly different in some cells.
