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.
Bovine blood keeps gold nanoparticles stable
May 14, 2013 10:35 am | News | CommentsAccording to recent research at Rice University, bovine serum albumin (BSA) forms a protein “corona” around gold nanoparticles that keeps them from aggregating, particularly in high-salt environments like seawater. The discovery could lead to improved biomedical applications and contribute to projects that use nanoparticles in harsh environments.
New insight into early growth of solid thin-films
May 14, 2013 10:07 am | News | CommentsThin films sometimes grow layer by layer, each layer one atom thick, while in other cases atoms deposited onto a surface form 3D islands that grow, impinge, and coalesce into a continuous film. Scientists have traditionally assumed that the islands are homogeneous and coalesce at roughly the same time. In a recent study, researchers have discovered that the process is more dynamic than suggested by the traditional view.
Microgravity nanomedicine experiment may go to Space Station
May 14, 2013 10:00 am | News | CommentsNearly all drugs taken orally spike in concentration, decay quickly, and are only at their peak effectiveness for a short period of time. working on a solution―nanocapsules implanted beneath the skin that release pharmaceutical drugs through a nanochannel membrane and into the body at a sustained, steady rate. To design better nanochannels for a given drug, the team is hoping to use the International Space Station.
Researchers develop synthetic HDL cholesterol nanoparticles
May 14, 2013 9:46 am | News | CommentsA new study by University of Georgia researchers documents a technological breakthrough: Synthetic high density lipoprotein (HDL) nanoparticles. A completely biodegradable synthetic version of the so-called good cholesterol, the nanoparticles represent a potential new detection and therapy regimen for atherosclerosis.
Budget cuts pare real-time monitoring of volcanoes
May 14, 2013 8:09 am | by Rachel D’Oro, Associated Press | News | CommentsWorldwide, hundreds of flights are diverted each year because of volcanic activity. Scientists monitoring Alaska's volcanoes have been forced to shut down stations that provide real-time tracking of eruptions and forgo repairs of seismic equipment amid ongoing federal budget cuts—moves that could mean delays in getting vital information to airline pilots and emergency planners.
GM says supercomputers to keep recalls in check
May 13, 2013 3:31 pm | by TOM KRISHER - AP Auto Writer - Associated Press | News | CommentsGeneral Motors says a new supercomputer data storage center and efforts to write its own software are paying off. The company formally opened a giant data center on Monday in the Detroit suburb of Warren, Mich. The Detroit automaker says the changes are examples of how it's moving faster to cut costs and serve customers better.
Physicists light “magnetic fire” to reveal energy's path
May 13, 2013 3:27 pm | News | CommentsResearch on bursts of energy within magnetic systems dates back two decades. But scientists haven't been able to measure and understand what prompts this phenomenon, known as "magnetic deflagration." New York University physicists have uncovered how energy is released and dispersed in magnetic materials in a process akin to the spread of forest fires.
The mechanism that puts the curl in the curling stone revealed
May 13, 2013 3:10 pm | News | CommentsIn the curling sport, the players shoot their stones along the ice so that they slowly slide towards the target area, almost 30 m away. The game has its name from the slightly curved "curled" path taken by the stone, when released with a slow rotation. Researchers from Uppsala University in Sweden can now reveal the mechanism behind this curving path.
