It鈥檚 no secret that Mars is a beaten and battered planet -- astronomers have been peering for centuries at the violent impact craters created by cosmic buckshot pounding its surface over billions of years. But just how beat up is it?

A team led by the University of Colorado Boulder looking for organisms that eke out a living in some of the most inhospitable soils on Earth has found a hardy few. A new DNA analysis of rocky soils in the Martian-like landscape on some volcanoes in South America has revealed a handful of bacteria, fungi and other rudimentary organisms called archaea, which seem to have a different way of converting energy than their cousins elsewhere in the world.

An international research team led by the University of Colorado Boulder has generated the first laser-like beams of X-rays from a tabletop device, paving the way for major advances in many fields including medicine, biology and nanotechnology development.

University of Colorado Boulder students and faculty have been selected to develop a remotely operable, robotic garden to support future astronauts in deep space. The project is one of five university proposals selected to participate in the 2013 Exploration Habitat (X-Hab) Academic Innovation Challenge led by NASA and the National Space Grant Foundation.

University of Colorado Boulder Professor Andrew Hamilton, doggedly determined to go where no man has gone before, continues to fascinate the public with his stunning and scientifically sound visualizations that take viewers into the guts of black holes.

A monthlong summer exhibit at the University of Colorado Boulder Art Museum will feature a dynamic new media composition based on innovative robotics technology. Called 鈥淪warm Wall,鈥� the large-scale interactive piece displays changing fields of color, light and sound that are driven by a distributed form of artificial intelligence.

Nate and Zach Huey are identical, 15-year-old twins, who, like most twins, are somewhat dissimilar. Nate runs cross country and track at Westminster High School. He specializes in mid-distance events like the two-mile run. Zach was a sprinter but suffered an injury that sidelined him. Nate is learning the guitar but doesn鈥檛 read music. He plays by 鈥渢ab鈥� (drawings showing where to place fingers on the fretboard). Zach reads music and plays trombone in the band. He enjoys it but likes other instruments, too.

Increases in the diversity of parasites that attack amphibians cause a decrease in the infection success rate of virulent parasites, including one that causes malformed limbs and premature death, says a new University of Colorado Boulder study.

On May 24, 1962, University of Colorado Boulder alumnus Scott Carpenter lifted off from Earth in NASA鈥檚 Aurora 7 space capsule mounted atop a Mercury-Atlas rocket at Cape Canaveral, Fla., swiftly climbing to roughly 165 miles in altitude.

On Sunday, May 20, Coloradans will see a 鈥渂ite鈥� taken out of the sun as the moon moves across the sun causing a partial solar eclipse. The eclipse starts at 6:22 p.m. with maximum eclipse at 7:30 p.m. and the sun will set at 7:50 p.m. Watch live this Sunday:
