Teams of astronomers at the California Institute of Technology and at the University of California, Berkeley, have discovered methane clouds near the south pole of Titan, resolving a fierce debate about whether clouds exist amid the haze of the moon's atmosphere.

The new observations were made usi

In the last few years, researchers have discovered more than 500 objects in the Kuiper belt, a gigantic outer ring in the outskirts of the solar system, beyond the orbit of Neptune. Of these, seven so far have turned out to be binaries--two objects that orbit each other. The surprise is that these binaries all seem to be pairs of widely separated objects of similar size. This is surprising because more familiar pairings, such as the Earth/moon system, tend to be unequal in size and/or rather close together.

In the subatomic particle family, the neutrino is a bit like a wayward red-haired stepson. Neutrinos were long ago detected-and even longer ago predicted to exist-but everything physicists know about nuclear processes says there should be a certain number of neutrinos streaming from the sun, yet there are nowhere near enough.

By analyzing stalagmites from caves in Sarawak, which is the Malaysian section of Borneo and the location of one of the world's oldest rain forests, and by studying deep-sea corals from the North Atlantic Ocean, California Institute of Technology researcher Jess Adkins will explore the vital link between the deep ocean, the atmosphere, and abrupt changes in global climates.

Scientists know quite a bit about surface conditions during the Last Glacial Maximum (LGM), a period that peaked about 18,000 years ago, when ice covered significant portions of Canada and northern Europe.

But to really understand the mechanisms involved in climate change, scientists need to have

Geologists just back from a reconnaissance of the 7.9-magnitude Alaska earthquake of November 3 confirm that rupture of the Denali fault was the principal cause of the quake.

In a study that combines state-of-the-art biological imaging with gene expression analysis, scientists at the California Institute of Technology have uncovered a fundamental insight into the way embryonic cells and tissue move about to form key structures along the vertebrate axis.

Planetary scientists at the California Institute of Technology have discovered a spherical body in the outskirts of the solar system. The object circles the sun every 288 years, is half the size of Pluto, and is larger than all of the objects in the asteroid belt combined.

Researchers at the California Institute of Technology announced today a new paradigm for large-scale integration of microfluidic devices. Using new techniques, they built chips with as many as 6,000 microvalves and up to 1,000 tiny individual chambers.

Genetic studies for decades have estimated that humans and chimpanzees possess genomes that are about 98.5 percent similar. In other words, of the three billion base pairs along the DNA helix, nearly 99 of every 100 would be exactly identical.
