NASA Mars Rover Opportunity Reveals Geological Mystery

NASA's long-lived rover Opportunity has returned an image of the Martian surface that is puzzling researchers.

NASA Selects Advanced Robotics Projects for Development

NASA has selected eight advanced robotics projects that will enable the agency's future missions while supporting the Obama administration's National Robotics Initiative.

Boeing Completes First Milestone for NASA's Commercial Crew Initiative

The Boeing Company completed its first performance milestone Aug. 23 for NASA's Commercial Crew Integrated Capability (CCiCap) initiative, which is intended to lead to the availability of human spaceflight transportation services for government and commercial customers.

Bendable crystals resolve properties of X-ray pulses

(Phys.org)—A frustrating flaw in a set of custom crystals for an instrument at SLAC National Accelerator Laboratory inspired a solution for an important scientific challenge: how to accurately measure the colors of each individual pulse from a powerful X-ray laser.

Pyrex Glass Isn’t As Shatterproof As It Once Was, Report Finds | 80beats

If you’ve ever poured hot water into a Pyrex glass dish and been shocked to see it fracture before your eyes, a new report may give you some insight into what’s going on. Pyrex glassware, which came out in 1915 and was long marketed as “icebox to oven” cookware that did not expand or compress when exposed to high heat or low temperatures, is no longer made of that hardy borosilicate glass.

New method for imaging defects in magnetic nanodevices

(Phys.org)—A team of researchers from the NIST Center for Nanoscale Science and Technology, the Royal Institute of Technology, Stockholm, and the University of Maryland have demonstrated a microscopy method to identify magnetic defects in an array of magnetic nanostructures. The method represents an important step towards identifying, measuring, and correcting the magnetic properties of defective devices in future information storage technologies. 

Scientists use levitation to create better pharmaceuticals with fewer side effects

(Phys.org)—It's not a magic trick and it's not sleight of hand – scientists really are using levitation to improve the drug development process, eventually yielding more effective pharmaceuticals with fewer side effects.

Scientists discover second purpose for vortex generators

(Phys.org)—An airplane's vortex generators, which look like small fins on its surface, improve the plane's aerodynamics similar to the way in which the dimples on a golf ball improve the ball's aerodynamics: by delaying "boundary layer separation." While this mechanism is widely known, a new study has shown that vortex generators can improve a plane's aerodynamics in a second way, and the researchers demonstrate this way in a wind tunnel for the first time.

A challenging task: LHC collides protons with lead ions for first time

(Phys.org)—At 1.26am today the Large Hadron Collider (LHC) collided protons with lead ions for the first time.

No more bubbles when boiling water

(Phys.org)—The research, which is the first of its kind, has identified a specially engineered steel surface that allows liquids to boil without bubbling.
