Caltech researchers stabilize microwave oscillators with optical frequencies from a silicon chip. The approach could ultimately replace more conventional methods that rely on crystal references—a technology in use since the 1920s.
This image shows the latest example of what Julia Greer, professor of materials science and mechanics, calls a fractal nanotruss. Greer's group has developed a three-step process for building such complex structures very precisely.
Building on their prior work, a team of neuroscientists at Caltech now report that rare patients who are missing connections between the left and right sides of their brain show a strikingly high incidence of autism. The study is the first to show a link between the two disorders.
An experiment just launched into orbit by Caltech researchers could be an important step toward understanding the protein that causes Huntington's disease—a devastating and untreatable hereditary disorder.
Apart from the inherent joy of pushing number theory forward through another generation, Dinakar Ramakrishnan points out that this field has interesting applications in both science and everyday life. "Quite often in science, you are counting..."
As reported in a paper published online today in the journal Nature, Caltech biologist David J. Anderson and his colleagues have genetically identified neurons that control aggressive behavior in the mouse hypothalamus.
Caltech biologist Elliot Meyerowitz and colleagues have found that the unusual shape of pavement cells, found on the leaves of flowering plants, represents a state of balance—an individual cell's tug-of-war to maintain structural integrity.
