Making frequency-hopping radios practical
May 15, 2013 7:45 am | by Larry Hardesty, MIT News Office | News | CommentsThe way in which radio spectrum is currently allocated to different wireless technologies can lead to gross inefficiencies. Cognitive radio serves as a solution. Different proposals for cognitive radio place different emphases on hardware and software, but the chief component of many hardware approaches is a bank of filters that can isolate any frequency in a wide band. Researchers have developed a new method for manufacturing such filters.
Scientists discover new uses for tiny carbon nanotubes
May 15, 2013 7:25 am | News | CommentsThe atom-sized world of carbon nanotubes holds great promise for a future demanding smaller and faster electronic components. The challenge has been figuring out how to incorporate all of these nanotubes' great properties into useful electronic devices. A new discovery by four scientists at the University of California, Riverside has brought us closer to the goal.
New technique helps robotic vehicles find their way
May 14, 2013 5:02 pm | News | CommentsA Wayne State University researcher understands that the three most important things about real estate also apply to small ground robotic vehicles: location, location, location. A recently published paper describes the development of a technique called LOBOT that provides accurate, real-time, 3D positions in both indoor and outdoor environments.
"Makers" 3D print shapes created using new design tool, bare hands
May 14, 2013 4:38 pm | News | CommentsA new design tool interprets hand gestures, enabling designers and artists to create and modify 3D shapes using only their hands as a "natural user interface" instead of keyboard and mouse. The tool, called Shape-It-Up, uses specialized computer algorithms and a depth-sensing camera to observe and interpret hand movements and gestures.
Livermore Lab, Cool Earth Solar partner on renewable energy demonstration project
May 14, 2013 2:53 pm | News | CommentsThe California Energy Commission has awarded $1.7 million to a partnership between Lawrence Livermore National Laboratory and Cool Earth Solar Inc. to conduct a community-scale renewable energy integration demonstration project at the Livermore Valley Open Campus.
Fracking brings economic boost, but risks raise concerns
May 14, 2013 2:42 pm | News | CommentsMost Michigan and Pennsylvania residents say fracking is good for the economy, but have concerns about chemicals used and other environmental risks, according to a University of Michigan survey. Fracking is the common term for hydraulic fracturing, which involves injecting a mixture of water, sand, and chemicals deep into the ground through encased wells at high pressure to create and expand fractures in the shale rock.
First precise MEMS output measurement technique unveiled
May 14, 2013 1:06 pm | News | CommentsResearchers in Europe have developed a new experimental system to gain accurate information on mechanical values and properties of any microelectromechanical (MEMS) device through electrical measurement. The technique works by applying a current across the device with a varying frequency and analyzes the harmonic content of the output voltage of the component parts.
Engineered biomaterial could improve success of medical implants
May 14, 2013 12:24 pm | News | CommentsIt’s a familiar scenario—a patient receives a medical implant and days later, the body attacks the artificial valve or device, causing complications to an already compromised system. Expensive medical devices and surgeries often are thwarted by the body’s natural response to attack something in the tissue that appears foreign. Now, University of Washington engineers have demonstrated in mice a way to prevent this sort of response.
Nanoscale alloys shine bright for medical applications
May 14, 2013 12:15 pm | News | CommentsAlloys like bronze and steel have been transformational for centuries, yielding machines necessary for industry. As scientists move toward nanotechnology, however, the focus has shifted toward creating alloys at the nanometer scale—producing materials with properties unlike their predecessors. Now, research demonstrates that nanometer-scale alloys possess the ability to emit light so bright they could have medical applications.
Navy to launch unmanned aircraft from carrier
May 14, 2013 11:38 am | by BROCK VERGAKIS - Associated Press - Associated Press | News | CommentsThe Navy will make its first attempt to launch an unmanned aircraft the size of a fighter jet from an aircraft carrier on Tuesday, marking a significant step toward the possibility of expanded drone use in future conflicts. The X-47B can reach an altitude of more than 40,000 feet, has a range of more than 2,100 nautical miles and can reach high subsonic speeds.
Vented Enclosures
May 14, 2013 11:35 am | Product Releases | CommentsAir Science USA has introduced a new series of vented enclosures that provide effective containment of airborne particulates during manipulation and transfer of potent compounds.
High-Resolution Stereomicroscopes
May 14, 2013 11:31 am | Product Releases | CommentsNikon Instruments has introduced two new stereomicroscopes—the Nikon SMZ25 and SMZ18 systems. The SMZ25 is fully motorized and uses the Nikon Perfect Zoom system, resulting in a large zoom ratio of 25:1 for high resolution and excellent fluorescence transmission capability.
Software spots, isolates cyberattacks to protect networked control systems
May 14, 2013 11:06 am | News | CommentsResearchers from North Carolina State University have developed a software algorithm that detects and isolates cyberattacks on networked control systems—which are used to coordinate transportation, power, and other infrastructure across the United States.
Study identifies key protein for cell death
May 14, 2013 10:49 am | by Anne Trafton, MIT News Office | News | CommentsWhen cells suffer too much DNA damage, they are usually forced to undergo programmed cell death, or apoptosis. However, cancer cells often ignore these signals, flourishing even after chemotherapy drugs have ravaged their DNA. A new finding may offer a way to overcome that resistance: A team has identified a key protein involved in an alternative death pathway known as programmed necrosis.
Grammar errors? The brain detects them even when you are unaware
May 14, 2013 10:40 am | News | CommentsYour brain often works on autopilot when it comes to grammar. That theory has been around for years, but University of Oregon neuroscientists have captured elusive hard evidence that people indeed detect and process grammatical errors with no awareness of doing so.
