Grand Canyon as Old as the Dinosaurs, Suggests New Study Led by CU-Boulder

An analysis of mineral grains from the bottom of the western Grand Canyon indicates it was largely carved out by about 70 million years ago — a time when dinosaurs were around and may have even peeked over the rim, says a study led by the University of Colorado Boulder.

The new research pushes back the conventionally accepted date for the formation of the Grand Canyon in Arizona by more than 60 million years, said CU-Boulder Assistant Professor Rebecca Flowers. The team used a dating method that exploits the radioactive decay of uranium and thorium atoms to helium atoms in a phosphate mineral known as apatite, said Flowers, a faculty member in CU-Boulder’s geological sciences department.

Researchers Develop New, Less Expensive Nanolithography Technique

Researchers from North Carolina State University have developed a new nanolithography technique that is less expensive than other approaches and can be used to create technologies with biomedical applications.

“Among other things, this type of lithography can be used to manufacture chips for use in biological sensors that can identify target molecules, such as proteins or genetic material associated with specific medical conditions,” says Dr. Albena Ivanisevic, co-author of a paper describing the research. Ivanisevic is an associate professor of materials science and engineering at NC State and associate professor of the joint biomedical engineering program at NC State and the University of North Carolina at Chapel Hill. Nanolithography is a way of printing patterns at the nanoscale. (more…)

What to Expect When Curiosity Starts Snapping Pictures

If a group of tourists piled out of a transport vehicle onto the surface of Mars, they’d no doubt start snapping pictures wildly. NASA’s Curiosity rover, set to touch down on the Red Planet the evening of Aug. 5 PDT (early morning EDT), will take a more careful approach to capturing its first scenic views.

The car-size rover’s very first images will come from the one-megapixel Hazard-Avoidance cameras (Hazcams) attached to the body of the rover. Once engineers have determined that it is safe to deploy the rover’s Remote Sensing Mast and its high-tech cameras, a process that may take several days, Curiosity will begin to survey its exotic surroundings.
