NASA’s Cassini spacecraft will make a close approach to the south polar region of Saturn’s moon Enceladus on April 14, 2012. Image credit: NASA/JPL-Caltech Less than three weeks after its last visit to the Saturnian moon Enceladus, JPL’s Cassini spacecraft re... More »
Many different species of nematodes were found by the Sternberg lab to communicate using the same types of chemical cues. [Credit: Caltech] All animals seem to have ways of exchanging information—monkeys vocalize complex messages, ants create scent trails to f... More »
This artist’s concept shows a “feeding,” or active, supermassive black hole with a jet streaming outward at nearly the speed of light. Such active black holes are often found at the hearts of elliptical galaxies. Not all black holes have jets, but when they do... More »
Infrared view of the Fomalhaut dust disk taken by the Herschel Space Observatory. New data reveal that comets are constantly banging into each other around the star, creating its dust disk. Image credit: ESA The Herschel Space Observatory has studied the dusty... More »
What happens to a stem cell at the molecular level that causes it to become one type of cell rather than another? At what point is it committed to that cell fate, and how does it become committed? The answers to these questions have been largely unknown. But n... More »
