The most destructive wildfire in Colorado's history began on Sept. 6, 2010. For four days, it burned an area roughly 10 square miles around Fourmile Canyon. It destroyed 168 homes, more than any previous fire in Colorado's ...

What happens when you put evolution on replay?

A team of scientists from the University of Arizona have engineered an instant replay switch for evolution. The technique, known as ancestral gene resurrection, inserts ancient genes into modern E. coli bacteria. It gives ...

Image: Hubble finds the calm after the galactic storm

The NASA/ESA Hubble Space Telescope caught sight of a soft, diffuse-looking galaxy that is probably the aftermath of a long-ago galactic collision. Two spiral galaxies, each perhaps much like the Milky Way, swirled together ...

Optical distance measurement at record-high speed

Microresonator-based optical frequency combs enable highly-precise optical distance ranging at a rate of 100 million measurements per second – publication in Science: Scientists of Karlsruhe Institute of Technology (KIT) ...

A laser focus on super water-repellent metals

In a laboratory at the University of Rochester, researchers are using lasers to change the surface of metals in incredible ways, such as making them super water-repellent without the use of special coatings, paints, or solvents.

CloudSat exits the 'A-train'

Mission managers at NASA's Jet Propulsion Laboratory in Pasadena, California, this week lowered the orbit of the nearly 12-year-old CloudSat satellite following the loss of one of its reaction wheels, which control its orientation ...

Video: The carbon cycle

As part of the way Earth works as a system, carbon is continuously passed between the ocean, the land and the atmosphere. This involves a range of different processes, some of which can be observed by satellites.
