Alloys 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.
The 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.
Air Science USA has introduced a new series of vented enclosures that provide effective containment of airborne particulates during manipulation and transfer of potent compounds.
Nikon 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.
Researchers 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.
When 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.
Your 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.
According 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.
Thin 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.
Nearly 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.
A 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.
Worldwide, 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.
General 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.
Research 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.
In 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.
