The discovery of a 'left-handed' magnetic field that pervades the universe could help explain a long standing mystery — the absence of cosmic antimatter. Planets, stars, gas and dust are almost entirely made up of 'normal' matter of the kind we are familiar with on Earth. But theory predicts that there should be a similar amount of antimatter, like normal matter, but with the opposite charge.
Researchers have successfully demonstrated pattern recognition using a magnonic holographic memory device, a development that could greatly improve speech and image recognition hardware. Pattern recognition focuses on finding patterns and regularities in data. The uniqueness of the demonstrated work is that the input patterns are encoded into the phases of the input spin waves.
For the first time, scientists have imaged thunder, visually capturing the sound waves. Although people see it as a flashing bolt, lightning begins as a complex process of electrostatic charges churning around in storm clouds. By studying the acoustic power radiated from different portions of the lightning channel, researchers can learn more about the origins of thunder as well as the energetic processes associated with lightning.
On a telescope at the summit of Mauna Kea in Hawaii, it’s not easy to put in a full night of work. At 14,000 feet, you’re operating at only 60 percent of the oxygen available at sea level, which makes concentrating difficult. Top that off with a shift that begins at 6:30 pm and ends at 6:30 am, and it becomes hard to imagine astronomers working like that year-round. Luckily, most of us don’t have to.
The major goals of HASP are to foster student excitement in an aerospace career path and to help address workforce development issues in this area. HASP provides a space test platform to encourage student research and stimulate the development of student satellite payloads and other space-engineering products. By getting the students involved with every aspect of the program, HASP hopes to enhance technical skills and research abilities.
Is thinking related to movement, such as the movement of your hand as you write? An unusual collaboration plays tongue-and-cheek with this possibility by creating a font based on the handwriting of one of science’s ultimate thinkers, Albert Einstein.
The Martian is Weir’s first novel. He started the book in 2009, researching it to be as realistic as possible based on existing technology, and posting it to his blog chapter by chapter. The story unfolded over the course of several years, but Weir has stated that he knows the exact date of each day in The Martian.
Protecting the world from destruction by asteroids sounds like superhuman power, but NASA scientists work tirelessly to ensure that humans today are protected from this potential harm. Asteroids need to be hunted in order to identify which ones may endanger Earth, and analyzing the big data puzzle of asteroid detection has been an arduous process. That is, until the power of crowdsourcing was discovered.
IBM scientists unveiled two critical advances towards the realization of a practical quantum computer. For the first time, they showed the ability to detect and measure both kinds of quantum errors simultaneously, as well as demonstrated a new, square quantum bit circuit design that is the only physical architecture that could successfully scale to larger dimensions.
NASA is bringing together experts spanning a variety of scientific fields for an unprecedented initiative dedicated to the search for life on planets outside our solar system. The Nexus for Exoplanet System Science, or “NExSS,” hopes to better understand the various components of an exoplanet, as well as how the planet stars and neighbor planets interact to support life.
World-famous physicist and cosmologist Stephen Hawking made a dramatic appearance at the Sydney Opera House via hologram at a sold-out public lecture on April 26, 2015. The world-first “Evening with Stephen Hawking” event, a night celebrating the phenomenal story of Professor Hawking, was the result of a partnership between UNSW, Cisco and the Sydney Opera House. Hawking beamed in via the latest in collaboration technology.
At first glance, there is not the slightest doubt: to us, the universe looks three-dimensional. But one of the most fruitful theories of theoretical physics in the last two decades is challenging this assumption. The "holographic principle” asserts that a mathematical description of the universe actually requires one fewer dimension than it seems. What we perceive as 3-D may just be the image of 2-D processes on a huge cosmic horizon.
On April 25, 1990, astronauts aboard the Space Shuttle Discovery deployed the Hubble Space Telescope into Earth orbit and launched a new era of astronomical discovery. In its quarter-century in orbit, the world’s first space telescope has transformed our understanding of our solar system and beyond. Now, 25 years later, organizations around the world are joining in a celebration of this remarkable observatory.
How is lightning initiated in thunderclouds? This is difficult to answer — how do you measure electric fields inside large, dangerously charged clouds? It was discovered, more or less by coincidence, that cosmic rays provide suitable probes to measure electric fields within thunderclouds. The measurements, including the strength of the electric field at a certain height in the cloud, were performed with the LOFAR radio telescope.
Astronomers may have found "the largest individual structure ever identified by humanity." In 2004, astronomers examining a map of radiation left over from the Big Bang discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in the infant universe, but a spot this large and this cold was unexpected.
COMSOL 5.1 is a major upgrade that delivers new and enhanced functionality across all products, including COMSOL Multiphysics and the Application Builder and COMSOL Server, as well as the add-on modules. Among the significant updates are enhancements to numerous core modeling and simulation capabilities and an improved user experience for application design.
If you’re designing a new computer, you want it to solve problems as fast as possible. Just how fast is possible is an open question when it comes to quantum computers, but physicists at the National Institute of Standards and Technology have narrowed the theoretical limits for where that “speed limit” is.
Part of the Southern Patagonian Ice Field – the world's second largest contiguous extrapolar ice field – and two lakes are pictured in this image of Argentina’s Los Glaciares National Park. The park was named a UNESCO World Heritage site in 1981, is situated in the area around Lake Viedma and the country’s largest freshwater Lake Argentino.
Physicists have developed techniques that enable them to simulate high-speed impacts in artificial soil and sand in the lab, and then watch what happens underground close-up, in super slow motion. They report that materials like soil and sand actually get stronger when they are struck harder.
A new technology in development has the potential to revolutionize the sourcing of renewable energy from rivers.
As we approach the miniaturization limits of conventional electronics, alternatives to silicon-based transistors — the building blocks of the multitude of electronic devices we’ve come to rely on — are being hotly pursued. Inspired by the way living organisms have evolved in nature to perform complex tasks with remarkable ease, a group of researchers is exploring similar “evolutionary” methods to create information processing devices.
Researchers have long believed that supercomputers give universities a competitive edge in scientific research, but now they have some hard data showing it’s true. A Clemson University team found that universities with locally available supercomputers were more efficient in producing research in critical fields than universities that lacked supercomputers.
Legions of viruses that infect the leaves of tobacco plants could be the key to making power plants safer, heating and cooling buildings more efficient and “really kick-ass computers,” or to the liquid cooling of high-powered electronic devices, like radar systems. These tiny protein bundles, which were once a threat to a staple cash crop, are now helping researchers better understand the processes of boiling and condensation.
The core circuits of quantum teleportation, which generate and detect quantum entanglement, have been successfully integrated into a photonic chip by an international team of scientists from the universities of Bristol, Tokyo, Southampton and NTT Device Technology Laboratories. These results pave the way to developing ultra-high-speed quantum computers and strengthening the security of communication.
