| Scientists 'bend' elastic waves with new metamaterials that could have commercial applications Posted: 22 Jan 2015 02:00 PM PST Sound waves passing through the air, objects that break a body of water and cause ripples, or shockwaves from earthquakes all are considered 'elastic' waves. These waves travel at the surface or through a material without causing any permanent changes to the substance's makeup. Now, engineering researchers have developed a material that has the ability to control these waves, creating possible medical, military and commercial applications with the potential to greatly benefit society. |
| Gold 'nano-drills' help with DNA analysis Posted: 22 Jan 2015 05:45 AM PST Spherical gold particles are able to 'drill' a nano-diameter tunnel in ceramic material when heated. This is an easy and attractive way to equip chips with nanopores for DNA analysis, for example, nanotechnologists report. |
| Engineers develop world's longest 'flat pack' arch bridge Posted: 22 Jan 2015 05:45 AM PST Civil Engineers and pre-cast concrete specialists have developed the world's longest 'flat pack' arch bridge. |
| Self-powered intelligent keyboard could provide a new layer of security Posted: 22 Jan 2015 05:35 AM PST By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered non-mechanical intelligent keyboard could provide a stronger layer of security for computer users. The intelligent keyboard records each letter touched, but also captures information about the amount of force applied to the key and the length of time between one keystroke and the next. Such typing style is unique to individuals, and so could provide a new biometric for securing computers from unauthorized use. |
