| First successful 'spoofing' of unmanned aerial vehicles Posted: 29 Jun 2012 06:18 PM PDT Scientists demonstrated for the first time that the GPS signals of an unmanned aerial vehicle (UAV), or drone, can be commandeered by an outside source -- a discovery that could factor heavily into the implementation of a new federal mandate to allow thousands of civilian drones into the US airspace by 2015.  |
| New technique controls graphite to graphene transition Posted: 29 Jun 2012 06:15 PM PDT Physicists have found a way to systematically study and control the transition of graphite, the "lead" found in pencils, to graphene, one of the strongest, lightest and most conductive materials known.  |
| Cloud computing: Same weakness found in seven cloud storage services Posted: 29 Jun 2012 11:24 AM PDT Cloud storage services allow registration using false e-mail addresses – experts see the possibility for espionage and malware distribution.  |
| Not-so-precious: Stripping gold from AFM probes allows better measurement of picoscale forces Posted: 28 Jun 2012 01:46 PM PDT Researchers found that removing an AFM probe's gold coating -- until now considered helpful -- greatly improved force measurements performed in a liquid, the medium favored for biophysical studies such as stretching DNA or unfolding proteins.  |
| NIST goes the distance for the Olympics Posted: 28 Jun 2012 01:46 PM PDT In yet another Olympian feat of measurement, researchers recently calibrated a tape that will be used to measure out the distance of this summer's Olympic marathon -- a distance of 26 miles 385 yards -- to one part in 1,000.  |
| Competitive swimmers can have movements tracked wirelessly through water Posted: 28 Jun 2012 01:44 PM PDT Training sessions for Team GB's swimmers have been getting a helping hand from a new system incorporating cutting-edge movement tracking and sensor technologies. From starting dives to tumble turns the state-of-the-art coaching aid is the first of its kind to be able to track movement wirelessly through water.  |
| Novel clay-based coating may point the way to new generation of green flame retardants Posted: 28 Jun 2012 11:57 AM PDT In searching for better flame retardants for home furnishings -- the largest source of fuel in house fires -- researchers defied the conventional wisdom and literally hit a wall, one made of clay. That turns out to be a good thing.  |
| Posted: 27 Jun 2012 12:41 PM PDT How do fireworks make the colors that keep eyes glued to the sky? What's inside includes a fuse and fuel to make the firework explode. Also inside are one or more capsules or packets containing metals ground into tiny particles. When the firework explodes, the metal particles start oxidizing, which creates heat.  |
| Nuclear landscape mapped: Number of isotopes allowed by laws of physics calculated Posted: 27 Jun 2012 11:25 AM PDT A supercomputer has calculated the number of isotopes allowed by the laws of physics. Physicists used a quantum approach known as density functional theory, applying it independently to six leading models of the nuclear interaction to determine that there are about 7,000 possible combinations of protons and neutrons allowed in bound nuclei with up to 120 protons (a hypothetical element called "unbinilium").  |
