Scientists and science fiction writers alike have dreamed of aircrafts that are propelled by beams of light rather than conventional fuels. Now, a new method for improving the thrust generated by such laser-propulsion systems may bring them one step closer to practical use. A new system integrates a laser-ablation propulsion system with the gas blasting nozzles of a spacecraft.
As transistors get smaller, they also grow less reliable. Increasing their operating voltage can...

Nikon has revealed the winners of the 40th annual Nikon Small World Photomicrography Competition, awarding first prize to veteran competitor Rogelio Moreno of Panama for capturing a rarely seen image of a rotifer’s open mouth interior and heart-shaped corona. A computer system programmer by occupation, Moreno is a self-taught microscopist whose photomicrograph serves to show just how close the beauty and wonder of the micro-world truly is.
In a darkened, hangar-like space inside MIT’s Building 41, a small, Roomba-like robot is trying to make up its mind. Standing in its path is an obstacle — a human pedestrian who’s pacing back and forth. To get to the other side of the room, the robot has to first determine where the pedestrian is, then choose the optimal route to avoid a close encounter.
The control of modern infrastructure, such as intelligent power grids, needs lots of computing capacity. Scientists have developed an algorithm that might revolutionize these processes. With their new software, researchers are able to forego the use of considerable amounts of computing capacity, enabling what they call micro mining.

Superconductors and magnetic fields do not usually get along. But a research team has produced new evidence for an exotic superconducting state, first predicted a half-century ago, that can indeed arise when a superconductor is exposed to a strong magnetic field.
Most people who know of origami think of it as the Japanese art of paper folding. Though it began centuries ago, origami became better known to the world in the 20th century when it evolved into a modern art form. In the 21st century, origami has caught the attention of engineers who are using it to create all sorts of new structures — from collapsible packaging to airbags for cars. Origami has even found its way into space.
Physicists have made important discoveries regarding Bs meson particles — something that may explain why the universe contains more matter than antimatter. At CERN, Stone and his research team have studied two landmark experiments that took place at Fermilab, a high-energy physics laboratory near Chicago, in 2009.
A study by an international team, including the University of Southampton, has shown population maps based on anonymous mobile phone call record data can be as accurate as those based on censuses. Their findings show maps made using mobile records are detailed, reliable and flexible enough to help inform infrastructure and emergency planners; particularly in low income countries, where recent population density information is often scarce.
This magnificent new image taken with the NASA/ESA Hubble Space Telescope shows the edge-on spiral galaxy NGC 4206, located about 70 million light-years away from Earth in the constellation of Virgo. Captured here are vast streaks of dust, some of which are obscuring the central bulge, which can just be made out in the center of the galaxy.
The Council on Competitiveness has released a new report that explores the value of government leadership in supercomputing for industrial competitiveness, titled Solve. The Exascale Effect: the Benefits of Supercomputing Investment for U.S. Industry. As the federal government pursues exascale computing to achieve national security and science missions, Solve examines how U.S.-based companies also benefit from leading-edge computation
Huygens Titan is lightweight software that indexes, finds and shows 2-D to 5-D microscopic image data. It can read all common microscope formats from any folder and subdirectory on any location to which a user has access. The software does not alter or move images.
This 40X photo shows abdominal segments of net-winged midge larvae. It received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using stereomicroscopy.
President Barack Obama is expanding his push for increased manufacturing in the United States by directing federal money toward new technologies, apprenticeship programs and competitions designed to assist small manufacturers. The White House announced the executive actions October 27, 2014, as part of the day's focus on manufacturing, which administration officials consider one of the bright spots of the economic recovery.
Projecting images on curved screens poses a dilemma. The sharper the image, the darker it is. A novel optical approach brings brightness and sharpness together for the first time on screens of any curvature — and additionally allows about 10,000-times faster projection rates. Researchers have applied a proven approach used with cameras.
Unmanned aerial vehicles, or drones, can collect detailed information in real time at relatively low cost for ecological research. In a new Opinion piece published in the Cell Press journal Trends in Parasitology, experts demonstrate that drones can be used to understand how environmental factors influence the spread of infectious diseases.
A Google executive has broken the sound barrier and set several skydiving records over the southern New Mexico desert after taking a leap from the edge of space. Alan Eustace's supersonic jump from a high-altitude, helium-filled balloon is part of a project by Paragon Space Development and its Stratospheric Explorer team. The goal is to develop a self-contained commercial spacesuit that would allow people to explore the stratosphere.
New maps of Saturn’s moon Titan reveal large patches of trace gases shining brightly near the north and south poles. These regions are curiously shifted off the poles, to the east or west, so that dawn is breaking over the southern region while dusk is falling over the northern one.
The sun emitted a significant solar flare on October 19, 2014, peaking at 1:01 a.m. EDT. NASA's Solar Dynamics Observatory, which is always observing the sun, captured this image of the event in extreme ultraviolet wavelength of 131 Angstroms — a wavelength that can see the intense heat of a flare and that is typically colorized in teal.
NASA's Mars Exploration Rover Opportunity captured images of a comet passing much closer to Mars than any previous known comet flyby of Earth or Mars. The images of comet Siding Spring were taken against a backdrop of the pre-dawn Martian sky on October 19, 2014. Images of comet A1 Siding Spring from the rover's panoramic camera (Pancam) are online.
Scientists at the Universities of Bonn and Cardiff see good times approaching for astrophysicists after hatching a new observational strategy to distill detailed information from galaxies at the edge of the Universe. Using two world-class supercomputers, the researchers were able to demonstrate the effectiveness of their approach by simulating the formation of a massive galaxy at the dawn of cosmic time.
A research team has been awarded approximately $58 million to analyze deposits of frozen methane under the Gulf of Mexico that hold enormous potential to increase the world’s energy supply.
