NuSTAR Space Telescope Blasts Off

This morning, NASA's NuSTAR telescope was launched into the low-Earth orbit from which it will begin exploring the high-energy X-ray universe to uncover the secrets of black holes, the dense remnants of dead stars, energetic cosmic explosions, and even our very own sun.  

Variability Keeps The Body In Balance

Using mathematical theory and software tools, Caltech researcher John Doyle studies why a variable heart rate is a sign of health and fitness.

A New Way to Prevent the Spread of Devastating Diseases

Researchers around the country are adopting a technique developed in the Caltech lab of Nobel Laureate David Baltimore to try to guard against infection. The method, called VIP, was originally designed to trigger an immune response to HIV, and because of its success with HIV is now being studied, in mice, for protection against influenza, malaria, hepatitis C, and tuberculosis.

Sensing Neuronal Activity With Light

A technique developed by Caltech researchers uses a genetic tool and light to view and map neuronal circuits.

Slimy Fish and the Origins of Brain Development

Work at Caltech's unique lamprey facility provides important insights about the evolutionary history of vertebrate brain development.

Ceramics Don't Have To Be Brittle

Caltech materials scientist Julia Greer and her students have developed a method for constructing new structural materials by taking advantage of the unusual properties that solids can have at the nanometer scale, where features are measured in billionths of meters. In a paper published in the September 12 issue of the journal Science, the Caltech researchers explain how they used the method to produce a ceramic (e.g., a piece of chalk or a brick) that contains about 99.9 percent air yet is incredibly strong, and that can recover its original shape after being smashed by more than 50 percent.

Tipping the Balance of Behavior

Caltech researchers have discovered a seesaw-like circuit in the brain that controls the choice between social and repetitive self-oriented behaviors in mice.

Textbook Theory Behind Volcanoes May Be Wrong

In the typical textbook picture, volcanoes, such as those that are forming the Hawaiian islands, erupt when magma gushes out as narrow jets from deep inside Earth. But that picture is wrong, according to a new study.

Seeing Protein Synthesis in the Field

Caltech researchers have developed a novel way to visualize proteins generated by microorganisms in their natural environment—including the murky waters of Caltech's lily pond.

Programmed to Fold: RNA Origami

Researchers from Aarhus University in Denmark and Caltech have developed a new method for organizing molecules on the nanoscale. Inspired by techniques used for folding DNA origami—first invented by Paul Rothemund, a senior research associate in computation and neural systems in the Division of Engineering and Applied Science at Caltech—the team, which includes Rothemund, has fabricated complicated shapes from DNA's close chemical cousin, RNA.
