A Caltech-led team of Mars Science Laboratory scientists has found that a surprisingly Earth-like martian rock offers new insight into the history of Mars's interior and suggests parts of the red planet may be more like our own than we ever knew.
When termites munch on wood, the small bits are delivered to feed a community of unique microbes living in their guts, and in a complex process involving multiple steps, these microbes turn the hard, fibrous material into a nutritious meal for the termite host. One key step uses hydrogen to convert carbon dioxide into organic carbon—a process called acetogenesis—but little is known about which gut bacteria play specific roles in the process.
Bruce Churchill Murray, Caltech Professor of Planetary Science, Emeritus, and former head of NASA's Jet Propulsion Laboratory (JPL), succumbed to complications of Alzheimer's disease on August 29, 2013. He was 81.
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.
