Study Shows How to Self-Propel Subatomic Particles

Using a new variation on the methods used to bend light, a team of physicists reveal that subatomic particles can be induced to speed up all by themselves without the application of any external forces. Some physical principles have been considered immutable since the time of Isaac Newton: Light always travels in straight lines. No […]

Extending Einstein-Podolsky-Rosen Quantum Mechanics Paradox

Using an optical network, researchers experimentally confirm that entanglement associated with the EPR paradox can be shared over three or more distinct optical systems. An international team, including researchers from Swinburne University of Technology, has demonstrated that the 1935 Einstein-Podolsky-Rosen (EPR) quantum mechanics paradox may be extended to more than two optical systems, paving the […]

Decoding the Gravitational Evolution of Dark Matter Halos

A newly published study allows the distribution of dark matter halos to be more accurately predicted by using a detailed comparison between theory and simulations. Researchers at Kavli IPMU and their collaborators have revealed that considering environmental effects such as a gravitational tidal force spread over a scale much larger than a galaxy cluster is […]

First Direct Measurement of Gravity’s Curvature

A newly published study details how a team of physicists simultaneously measured gravity with cold atoms at three different heights to achieve the first direct measurement of the gravity-field curvature. Earth’s gravitational pull gradually decreases with increasing altitude, and researchers have detected the differences even over several vertical feet within a lab, using the extreme […]

New Understanding of How to Halt Photons

A newly published study from MIT reveals the mechanism responsible for trapping the light, showing that this trapped state is much more stable than had been thought. Researchers at MIT who succeeded last year in creating a material that could trap light and stop it in its tracks have now developed a more fundamental understanding […]

Image of the Motion of the Two Electrons in a Helium Atom

Using attosecond-timed laser flashes, a team of physicists has become the first to image and control the motion of the two electrons in a helium atom. Physicists are continuously advancing the control they can exert over matter. A German-Spanish team working with researchers from the Max Planck Institute for Nuclear Physics in Heidelberg has now […]

New Mathematical Relationship for Superconductors

Engineers from MIT have discovered a new mathematical relationship between material thickness, temperature, and electrical resistance that appears to hold in all superconductors. The result could shed light on the nature of superconductivity and could also lead to better-engineered superconducting circuits for applications like quantum computing and ultralow-power computing. The findings are described in the […]

Engineers Stiffen Solids with Liquid Inclusions

Engineers from Yale University have strengthened solid materials by using very small embedded liquid droplets. Engineers at Yale University have discovered that the stiffness of liquid drops embedded in solids has something in common with Goldilocks: While large drops of liquids are softer than the solid that surrounds them, extremely tiny drops of liquid can […]

Researchers Use Real Data to Measure the Cosmos

Scientists from the Imperial College London have used data, rather than calculations related to general relativity, to measure large distances in the Universe for the first time. A research team from Imperial College London and the University of Barcelona has used data from astronomical surveys to measure a standard distance that is central to our […]

Hunting for Dark Matter in a Gold Mine

A team of scientists is building a supersized version of the dark matter detector Lux, called Lux-Zeplin, which will be roughly 100 times more sensitive to dark matter than its predecessor. “What really impressed me was the trip down,” said astrophysicist James Buckley, PhD, speaking of the vertical mile he traveled to get to the […]

Superconductivity without Cooling

New research details how scientists used an infrared laser pulse to briefly modify the structure of a high-temperature superconductor, removing its electrical resistance at room temperature. Superconductivity is a remarkable phenomenon: superconductors can transport electric current without any resistance and thus without any losses whatsoever. It is already in use in some niche areas, for […]

Neutron Star-Black Hole Binary

A new study examines in what sense a neutron star-black hole binary could the ‘holy grail’ for testing gravity. The intermittent light emitted by pulsars, the most precise timekeepers in the universe, allows scientists to verify Einstein’s theory of relativity, especially when these objects are paired up with another neutron star or white dwarf that […]

Engineers Take a Step Toward Using Light Instead of Wires Inside Computers

Using a new algorithm, engineers from Stanford University have developed a prism-like device that can split a beam of light into different colors and bend the light at right angles, a development that could eventually lead to computers that use optics, rather than electricity, to carry data. They describe what they call an “optical link” […]

Gravity May Have Saved the Universe

A newly published study details how the spacetime curvature provided the stability needed for the universe to survive after the Big Bang. Studies of the Higgs particle – discovered at CERN in 2012 and responsible for giving mass to all particles – have suggested that the production of Higgs particles during the accelerating expansion of […]

A Nanolamp with Lightning-Fast Switch

Scientists have developed a light source which converts an electrical voltage pulse into a light pulse by means of a single molecule, possibly serving as a prototype for nano-components that convert electrical into optical signals with gigahertz frequencies. Information is processed and transmitted by ever-smaller components, sometimes with electrons and sometimes with light. Scientists at […]
