Caltech engineers have mimicked lightweight yet strong biological materials by creating nanostructured, hollow ceramic scaffolds, and have found that their small building blocks, or unit cells, display remarkable strength and resistance to failure despite being more than 85 percent air.

One of the many counterintuitive and bizarre insights of quantum mechanics is that even in a vacuum—what many of us think of as an empty void—all is not completely still. Low levels of noise, known as quantum fluctuations, are always present. Always, that is, unless you can pull off a quantum trick. And that's just what a team led by researchers at the California Institute of Technology (Caltech) has done.

Engineers at the California Institute of Technology (Caltech) have devised a method to convert a relatively inexpensive conventional microscope into a billion-pixel imaging system that significantly outperforms the best available standard microscope. Such a system could greatly improve the efficiency of digital pathology.

An international team of researchers, including Caltech's Geoffrey Blake, has used the Atacama Large Millimeter/submillimeter Array (ALMA) to capture the first image of a snow line around a Sun-like star. The findings appear in the current issue of Science Express.

Researchers at the California Institute of Technology (Caltech) have discovered evidence for an ancient delta on Mars where a river might once have emptied into a vast ocean. This ocean, if it existed, could have covered much of Mars's northern hemisphere—stretching over as much as a third of the planet.

A team of researchers led by newly arrived Caltech biologist Mitchell Guttman and Kathrin Plath of UCLA, has figured out how some RNA molecules take advantage of their position within the 3-D structure of genomic material to home in on targets.

Economists argue that the dominant players in a market almost always make well-informed and objective decisions. Psychologists, on the other hand, say that markets are not immune from human irrationality. Now, a new analysis shows that markets are indeed susceptible to psychological phenomena.
