Earth and Mercury are both rocky planets with iron cores, but Mercury's interior differs from Earth's in a way that explains why the planet has such a bizarre magnetic field, UCLA planetary physicists and colleagues report.
Physicists are one step closer to proving the reliability of a quantum computer – a machine which promises to revolutionise the way we trade over the internet and provide new tools to perform powerful simulations.
Can neutrons be located at a different place than their own spin? A quantum experiment, carried out by a team of researchers from the Vienna University of Technology, demonstrates a new kind of quantum paradox
New findings from a NASA-funded instrument have resolved a decades-old puzzle about a fog of low-energy X-rays observed over the entire sky. Thanks to refurbished detectors first flown on a NASA sounding rocket in the 1970s, astronomers have now confirmed the long-held suspicion that much of this glow stems from a region of million-degree interstellar plasma known as the local hot bubble, or LHB.
Astronomers at the University of British Columbia have collaborated with international researchers to calculate the precise mass of the Milky Way and Andromeda galaxies, dispelling the notion that the two galaxies have similar masses.
The Syracuse University Experimental High Energy Physics Group has several reasons to celebrate—more than five million, in fact. The elite team of physicists, which includes professors Marina Artuso, Steven Blusk, Tomasz Skwarnicki and Sheldon Stone, was recently awarded $5.2 million by the National Science Foundation (NSF) to construct a new particle physics detector, known as an Upstream Tracker (UT).
Researchers from the Vienna University of Technology have performed the first separation of a particle from one of its properties. The study, carried out at the Institute Laue-Langevin (ILL) and published in Nature Communications, showed that in an interferometer a neutron's magnetic moment could be measured independently of the neutron itself, thereby marking the first experimental observation of a new quantum paradox known as the 'Cheshire Cat'.
Over the vast, empty reaches of interstellar space, countless small molecules tumble quietly though the cold vacuum. Forged in the fusion furnaces of ancient stars and ejected into space when those stars exploded, these lonely molecules account for a significant amount of all the carbon, hydrogen, silicon and other atoms in the universe. In fact, some 20 percent of all the carbon in the universe is thought to exist as some form of interstellar molecule.
Idaho State University’s Idaho Accelerator Center has achieved a milestone in nuclear medicine that promises hope to cancer patients. Scientists at the Center have used linear accelerators to produce isotopes that now can be assessed in the treatment of cancer.
Scientists using mission data from NASA’s Cassini spacecraft have identified 101 distinct geysers erupting on Saturn’s icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach from the moon’s underground sea all the way to its surface.
Following the success of the first TEDxCERN event last year, CERN will be hosting a second TEDx conference on 24 September 2014 on the theme “Forward: Charting the future with science”. Some 15 speakers will present their innovative and ambitious projects, which apply science to respond to problems facing the world today and prepare for those of tomorrow.
A team of scientists at MPQ achieves a twentyfold amplification of single-photon signals with the help of an ultracold quantum gas.
Zecotek Photonics Inc., a developer of leading-edge photonics technologies for industrial, healthcare and scientific markets, today announced that it is now close to having its patented LFS scintillation crystals approved for use at the European Organization for Nuclear Research (CERN) in Switzerland.
For decades, many physicists have taken for granted a theory that electrons in high-temperature superconductors are nudged into “Cooper pairs” that can carry an electric current without resistance by their interaction with the magnetic fields of nearby atoms. Sensitive measurements at Cornell have finally supplied the first experimental proof of the theory.
Physicists have identified the "quantum glue" that underlies a promising type of superconductivity -- a crucial step towards the creation of energy superhighways that conduct electricity without current loss.
