Researchers have identified a class of materials that displays clear evidence for stable skyrmions at room temperature and above, paving the way for the development of useful spintronics devices. Magnetic skyrmions are tiny, nanometer-sized magnetic-spin vortices that emerge in magnetic materials. Because they are so small, they could potentially be used as extremely dense memory devices.
A Purdue University study shows that targeting plants with red and blue LEDs provides energy-efficient lighting in contained environments, a finding that could advance the development of crop-growth modules for space exploration.
Sandcastles are a prime example of how adding a small amount of liquid to a granular material changes its characteristics. But understanding the effect of a liquid wetting randomly oriented fibers in a fibrous medium remains a mystery. Now, scientists have demonstrated that the spreading of the liquid is controlled by three key parameters: the amount of liquid on the fibers, the fibres’ orientation and the minimum distance between them.
Scientists are reporting the development of an implantable "artificial pancreas" that continuously measures a person's blood sugar, or glucose, level and can automatically release insulin as needed.
JILA researchers have designed a microscope instrument so stable that it can accurately measure the 3D movement of individual molecules over many hours--hundreds of times longer than the current limit measured in seconds.
A University of Texas at Arlington materials science and engineering team has developed a new energy cell that can store large-scale solar energy even when it's dark. The innovation is an advancement over the most common solar energy systems that rely on using sunlight immediately as a power source.
Over the years, the Hubble Space Telescope has allowed astronomers to look deep into the universe. There may be far fewer galaxies further out in the universe then might be expected, according to a new study led by Michigan State University.
Researchers at Sandia National Laboratories are working to lower the cost of solar energy systems and improve efficiencies in a big way, thanks to a system of small particles. This month, engineers lifted Sandia’s continuously recirculating falling particle receiver to the top of the tower at the National Solar Thermal Test Facility, marking the start of first-of-its-kind testing that will continue through 2015.
In the United States, electricity comes with the flip of a switch and heat arrives with the push of a button. Behind such convenience lies a massive infrastructure network that produces and distributes energy. And just like roads wear down and need to be repaved occasionally, this energy infrastructure degrades over time. Pipes can corrode and concrete can wear thin. Failure can be catastrophic...
A team of researchers describes the physics of magnesium hydride, one type of material that potentially could be used to store hydrogen fuel in future automobiles and other applications. Using a technique known as in situ transmission electron microscopy, the team tested different sized nanoparticles of magnesium hydride to gauge their mechanical properties and discovered how one might engineer the nanoparticles to make them better.
3-D imaging of plant branching structures is allowing researchers to see how exactly their internal tissues respond under stress, giving new insights into the design of potential new engineering materials, such as those used in aircraft. Researchers have developed a new method to visualize the junction between branches and stems. The method uses MRI to study how vascular tissue within the ramifications deforms under stress and strain.
Researchers have come up with a new solution to alleviate the environmental burden of discarded electronics. They have demonstrated the feasibility of making microwave biodegradable thin-film transistors from a transparent, flexible biodegradable substrate made from inexpensive wood, called cellulose nanofibrillated fiber (CNF). This work opens the door for green, low-cost, portable electronic devices in future.
An international team led by scientists from the University of Zurich finds that high-precision atomic clocks can be used to monitor volcanoes and potentially improve predictions of future eruptions. In addition, a ground-based network of atomic clocks could monitor the reaction of the Earth’s crust to solid Earth tides.
Storing solar energy as hydrogen is a promising way for developing comprehensive renewable energy systems. EPFL scientists have now developed a simple, unconventional method to fabricate high-quality, efficient solar panels for direct solar hydrogen production with low cost.
Researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have developed a detailed model of the source of a puzzling limitation on fusion reactions. The findings complete and confirm previous PPPL research and could lead to steps to overcome the barrier if the model proves consistent with experimental data.
NASA's Swift satellite detected a rising tide of high-energy X-rays from the constellation Cygnus on June 15, just before 2:32 p.m. EDT. The outburst came from V404 Cygni, a binary system located about 8,000 light-years away that contains a black hole. Every couple of decades the black hole fires up in an outburst of high-energy light, becoming an X-ray nova. Until the Swift detection, it had been slumbering since 1989.
The universe can be a very sticky place, but just how sticky is a matter of debate. That is because for decades cosmologists have had trouble reconciling the classic notion of viscosity based on the laws of thermodynamics with Einstein's general theory of relativity. However, a team from Vanderbilt University has come up with a fundamentally new mathematical formulation of the problem that appears to bridge this long-standing gap.
In recent years, there has been widespread media coverage of studies purporting to show that radiation from X-rays, CT scans and other medical imaging causes cancer. But such studies have serious flaws, including their reliance on an unproven statistical model.
Chemists and biologists have succeeded in designing and synthesizing an artificial cell membrane capable of sustaining continual growth, just like a living cell. Their achievement will allow scientists to more accurately replicate the behavior of living cell membranes, which until now have been modeled only by synthetic cell membranes without the ability to add new phospholipids.
Congenital heart experts have successfully integrated two common imaging techniques to produce a three-dimensional anatomic model of a patient’s heart.

The new technique could lead to the simple creation and manufacture of superconductors or high-efficiency solar cells and light sensors. By focusing lasers onto silicon buried under a clear layer of silicon dioxide, the group has perfected a way to reliably blast tiny cavities in the solid silicon.
Will next Saturday’s Tour de France prologue get the winner it deserves? New aerodynamic research shows that riders in a time trial can save vital seconds by riding closer to the following team car. Over a short distance like the prologue of the Tour de France, that can save as much as six seconds: enough to make the difference between winning and losing. On longer events like world championships, the effect can add up to tens of seconds.
Rice University has installed microscopes that will allow researchers to peer deeper than ever into the fabric of the universe. The Titan Themis scanning/transmission electron microscope, one of the most powerful in the United States, will enable scientists from Rice as well as academic and industrial partners to view and analyze materials smaller than a nanometer — a billionth of a meter — with startling clarity.
A team of researchers led by UCLA electrical engineers has demonstrated a new way to harness light particles, or photons, that are connected to each other and act in unison no matter how far apart they are — a phenomenon known as quantum entanglement.
