Imagine the world waking up one morning to discover that all compasses pointed south instead of north. It’s not as bizarre as it sounds. Earth’s magnetic field has flipped — though not overnight — many times throughout the planet’s history. A new study demonstrates that the last magnetic reversal 786,000 years ago actually happened very quickly, in less than 100 years — roughly a human lifetime.
Two research teams have found distinct solutions to a critical challenge that has held back the realization of super powerful quantum computers. The teams, working in the same laboratories at UNSW Australia, created two types of quantum bits, or "qubits" — the building blocks for quantum computers — that each process quantum data with an accuracy above 99 percent.
The discovery of a new particle will “transform our understanding” of the fundamental force of nature that binds the nuclei of atoms, researchers argue. Led by scientists from the University of Warwick, the discovery of the new particle will help provide greater understanding of the strong interaction, the fundamental force of nature found within the protons of an atom’s nucleus.
On October 8, 2014, active regions on the sun combined to look something like a jack-o-lantern’s face. This image is a blend of 171 and 193 angstrom light as captured by the Solar Dynamics Observatory. The active regions appear brighter, because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona.
The special theory of relativity of Albert Einstein and quantum electrodynamics, which was formulated by, among others, Richard Feynman, are two important fundaments of modern physics. The research group of Wilfried Nörtershäuser re-examined these theories in experiments at the GSI Helmholtz Center for Heavy Ion Research. Nörtershäuser’s team has accelerated ions to velocities near the speed of light and illuminated them with a laser.
An international team of astronomers has been able to see into the heart of an exploding star, by combining data from telescopes that are hundreds or even thousands of kilometers apart. Highly-detailed images produced using radio telescopes from across Europe and America have pinpointed the locations where a stellar explosion (called a nova), emitted gamma rays (extremely high energy radiation).
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2014 to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura “for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources.”
Martin Perl, a Nobel Prize-winning physicist from Stanford University who discovered a subatomic particle known as the tau lepton, has died at age 87. The university said the retired professor, one of two American scientists who shared the Nobel Prize for physics in 1995, died at Stanford Hospital on September 30, 2014. He was recognized for work he did during the 1970s at the Stanford Linear Accelerator Center.
EPFL scientists have designed a first-ever experiment for demonstrating quantum entanglement in the macroscopic realm. Unlike other such proposals, the experiment is relatively easy to set up and run with existing semiconductor devices. Interest in entanglement is increasing today, as it challenges the foundations of quantum mechanics itself.
A Purdue-based startup is developing high-temperature "plasmonic metamaterials" that could dramatically increase data-storage capabilities, improve solar-cell and waste-heat recovery performance and provide a new avenue for clinical therapeutics.
Where are the quantum computers? Aren’t they supposed to be speeding up decryption and internet searches? After two decades of research, you still can’t find them in stores. Well, it took two decades or more of research dedicated to semiconductors and circuit integration before we had digital computers. For quantum computers too it will take technology more time to catch up to the science.
Scientists are to turn the Moon into a giant particle detector to help understand the origin of Ultra-High-Energy (UHE) cosmic rays — the most energetic particles in the Universe.
By combining a pair of solar cells made with a mineral called perovskite and low cost electrodes, scientists have obtained a 12.3 percent conversion efficiency from solar energy to hydrogen, a record using earth-abundant materials as opposed to rare metals.
Electricity and magnetism rule our digital world. Semiconductors process electrical information, while magnetic materials enable long-term data storage. A University of Pittsburgh research team has discovered a way to fuse these two distinct properties in a single material, paving the way for new ultrahigh density storage and computing architectures.
Computationally intensive research in Sweden will soon get a boost from the fastest academic supercomputer in the Nordic countries, to be installed in October 2014 at KTH Royal Institute of Technology. KTH is due to begin using the fastest academic supercomputer of any university in Scandinavia. A Cray XC30 with 1,676 nodes and a memory of 104.7 terabytes will be installed at KTH’s PDC Center for High Performance Computing.
Strong solar flares can bring down communications and power grids on Earth. By demonstrating how these gigantic eruptions are caused, physicists are laying the foundations for future predictions. The shorter the interval between two explosions in the solar atmosphere, the more likely it is that the second flare will be stronger than the first one.
For the first time, scientists have discovered how to produce ultra-thin "diamond nanothreads" that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymers. The core of the nanothreads is a long, thin strand of carbon atoms arranged just like the fundamental unit of a diamond's structure.
Governor Jindal and LSU President and Chancellor Alexander announced creation of the LSU Transformational Technology and Cyber Research Center, which will pursue major federal and commercial research projects in applied technology fields, leveraging the university’s unique strengths in such disciplines as supercomputing, cybersecurity and nanotechnology.
For centuries, scientific research has been about data, and as data in research continues to grow exponentially, so does the importance of how it’s stored. A key example of how the scientific field can tackle Big Data storage is DESY, a scientific research organization dedicated to providing scientists worldwide faster access to insights into samples, making optimal data management in a high-volume environment extremely critical.
The Alpha Magnetic Spectrometer collaboration has presented its latest results based on analysis of 41 billion particles detected with the space-based AMS detector aboard the International Space Station. The results, presented during a seminar at CERN, provide new insights into the nature of the mysterious excess of positrons observed in the flux of cosmic rays.
An international collaboration has achieved the synthesis of a new class of chemical compounds for superheavy elements. For the first time, a chemical bond was established between a superheavy element — seaborgium (element 106) in the present study — and a carbon atom.
Physicists have succeeded in teleporting the quantum state of a photon to a crystal over 25 kilometers of optical fiber. The experiment constitutes a first, and simply pulverizes the previous record of 6 kilometers achieved 10 years ago by the same team. Passing from light into matter, using teleportation of a photon to a crystal, shows that, in quantum physics, it's not the composition of a particle that is important, but rather its state
Physicist, string theorist and best-selling author Brian Greene will talk about the intersection of science, computing and society as he delivers the keynote address at SC14 this November. Described by The Washington Post as "the single best explainer of abstruse concepts in the world today," Brian Greene is one of the world's leading theoretical physicists and a brilliant, entertaining communicator of cutting-edge scientific concepts.
This image, captured by the Wide Field Imager at La Silla Observatory, shows two dramatic star formation regions in the southern Milky Way. The first of these, on the left, is dominated by the star cluster NGC 3603, located 20,000 light-years away, in the Carina-Sagittarius spiral arm of the Milky Way galaxy. The second object, on the right, is a collection of glowing gas clouds known as NGC 3576 that lies only about half as far from Earth.
Researchers have developed a technique for controlling the surface tension of liquid metals by applying very low voltages, opening the door to a new generation of reconfigurable electronic circuits, antennas and other technologies. The technique hinges on the fact that the oxide “skin” of the metal — which can be deposited or removed — acts as a surfactant, lowering the surface tension between the metal and the surrounding fluid.
