In the future, magnetic vortex structures — so-called skyrmions — have the potential to store and process information very efficiently. They could also be the basis for high-frequency components. For the first time, physicists have succeeded in characterizing the electromagnetic properties of insulating, semiconducting and conducting skyrmion-materials and have developed a unified theoretical description of their behavior.
A relentless global effort to shrink transistors has made computers continually faster, cheaper...
For the first time, researchers have produced a 3-D image revealing part of the inner structure...
Meteorologists sometimes struggle to accurately predict the weather here on Earth, but now we...
Researchers have assembled the largest and most accurate tree of life calibrated to time. Surprisingly, it reveals that life has been expanding at a constant rate, not slowing down.
Research has for the first time analyzed over 130,000 online news articles to find out how the 2012 US presidential election played out in the media.
Before scientists develop a full quantum computer, quantum physicists will have to create circuitry that takes advantage of the marvelous computing prowess promised by the quantum bit (“qubit”), while compensating for its high vulnerability to environmentally-induced error.
In 1976 several elongated comet-like objects were discovered on pictures taken with the UK Schmidt Telescope in Australia. Because of their appearance, they became known as cometary globules even though they have nothing in common with comets. The object shown in this new picture, CG4, which is also sometimes referred to as God’s Hand, is one of these cometary globules.
Micro-drones are being put to use in a large number of areas, where these small aircraft face extensive requirements while performing aerial observation tasks or when deployed in the field of disaster management. A newly developed concept summarizes some of these challenges.
This 20x photo of an ant eye received an honorable mention in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. It was taken by Noah Fram-Schwartz of Greenwich, CT, using reflected light.
This color image shows the southernmost portion of Phlegra Montes on Mars, a complex system of isolated hills, ridges and small basins that spans over 1400 kilometers from the Elysium volcanic region at about 30ºN and deep into the northern lowlands at about 50°N.
For the first time, researchers have directly measured a general law of how pedestrians interact in a crowd. This law can be used to create realistic crowds in virtual reality games and to make public spaces safer. People intuitively know how to navigate through crowds in a way that both minimizes distance traveled and avoids collisions. But the 'force' that governs human interactions has been previously unknown.
A NASA spacecraft is about to reach the end of a nearly eight-year journey and make the first rendezvous with a dwarf planet. The Dawn craft will slip into orbit around Ceres, a dwarf planet the size of Texas, on March 6, 2015. Unlike robotic landings or other orbit captures, the arrival won't be a nail-biter. Still, Dawn had to travel some three billion miles to reach the largest object in the asteroid belt between Mars and Jupiter.
The technology behind the camera that revealed the intricate, imperfect beauty of snowflakes is now able to expose their potential danger. About three years ago, a new high-speed camera captured free-falling ice crystals so well it might as well be yelling "freeze!" Now, a less expensive, hardier version with the same incredible capability has been designed for use by departments of transportation to anticipate road conditions.
Sci-fi solutions or making friends one at a time? Google and Facebook are taking different routes to expanding Internet use and access among the unconnected in developing countries. The two Internet giants gave updates on their efforts — and differing approaches — at the Mobile World Congress wireless show in Barcelona on March 2, 2015.
The U.S. Centers for Disease Control and Prevention (CDC) reports that the 2014 Ebola epidemic is the largest in history, affecting multiple countries in West Africa. As of February 26, 2015, the CDC had tracked 23,816 cases, and Ebola had already claimed nearly 10,000 lives.
Researchers focusing on a fictional zombie outbreak as an approach to disease modeling suggest heading for the hills, in the Rockies, to save your brains from the undead. Reading World War Z: An Oral History of the First Zombie War, and taking a graduate statistical mechanics class inspired a group of Cornell University researchers to explore how an "actual" zombie outbreak might play out in the U.S.
The drive toward exascale computing, renewed emphasis on data-centric processing, energy efficiency concerns, and limitations of memory and I/O performance are all working to reshape HPC platforms, according to Intersect360 Research’s Top Six Predictions for HPC in 2015. The report cites many-core accelerators, flash storage, 3-D memory, integrated networking, and optical interconnects as just some of the technologies propelling future...
This 100x photo of living green algae in interference phase contrast received an honorable mention in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. It was taken using a light microscope and Interphako contrast.
