Caltech and the Human Genome Project

Caltech faculty have played an integral part in the development of the Human Genome Project.

Physicists observe the quantum of heat flow

Physicists at the California Institute of Technology have announced the first observation of the quantum of thermal conductance. This discovery reveals a fundamental limit to the heat that can be conducted by objects of atomic dimensions.

The findings, reported in the April 27 issue of the journal Nature, could have profound implications for the future design of microscopic electronic devices and for the transmission of information, according to the research team leader, Caltech physics professor Michael Roukes.

Cosmologists reveal first detailed images of early universe

Caltech cosmologists and other scientists involved in an international collaboration have released the first detailed images of the universe in its infancy.

Caltech scientists develop first microscopic system of pumps and valves made from soft materials

PASADENA—Researchers at the California Institute of Technology have developed a pump that is less than one-half the width of a human hair. The device is a breakthrough in the 3-D microfabrication of soft materials and could be applied to revolutionize and simplify many technologies, including drug discovery and delivery, according to Caltech applied physics professor Stephen R. Quake and his colleagues, who report their findings in the April 7 issue of Science.

Using quantum atomistic computer simulations to solve industrial problems

PASADENA—In the world of engineering and applied science, ideas that look good on the drawing board often turn out to have annoying real-world problems, even though the finished products still look pretty good. An example is the aluminum car engine, which has the advantage of being lightweight, but tends to wear out more quickly than its heavier steel counterpart.

Caltech grad student's team first to detect radio emission from a brown dwarf

A graduate student in astronomy from the California Institute of Technology recently led a team of researchers in finding the first radio emission ever detected from a brown dwarf, an enigmatic object that is neither star nor planet, but something in between.

The discovery, reported in the March 15 issue of the journal Nature by lead author Edo Berger and his colleagues, demonstrates that brown dwarfs can flare 10,000 times more intensely than theory predicted.

East and West Antarctica once began separating but then stopped, new research shows

PASADENA—Earth was well on its way to having two Antarcticas long ago, but a tectonic separation between the eastern and western portions of the continent suddenly stopped after 17 million years of spreading, researchers say.

Physicists create atom-cavity microscope, track single atoms bound in orbit with single photons

In a promising development with applications to science at the single-atom level, physicists have constructed an "atom-cavity microscope" that tracks the motion of individual atoms.

Astrobiologists should look for both water and energy sources when searching for life on other worlds, researcher says

PASADENA—When planetary scientists first saw evidence of a water ocean beneath the frozen surface of Europa, everyone immediately began pondering the likelihood that the Jovian moon could harbor advanced life forms—perhaps even fishlike creatures.

But last summer a group of planetary scientists from the California Institute of Technology and Jet Propulsion Laboratory threw water on the theory—so to speak—when they took a novel approach and concluded that advanced life forms were not likely.

Snowball Earth episode 2.4 billion years ago was hard on life, but good for modern industrial economy, research shows

For the primitive organisms unlucky enough to be around 2.4 billion years ago, the first global freeze was a real wipeout, likely the worst in the history of life on Earth. Few of the organisms escaped extinction, and those that did were forced into an evolutionary bottleneck that altered the diversity of life for eons.
