  • Physicists make most precise measurement ever of the proton's magnetic moment

    An international collaboration of scientists from RIKEN's Ulmer Fundamental Symmetries Laboratory (FSL), Johannes Gutenberg-Universität Mainz, Max Planck Institute for Nuclear Physics, Heidelberg and GSI Darmstadt, have used high-precision techniques to make the most precise measurement to date of the magnetic moment of the proton, finding it to be 2.79284734462 plus or minus 0.00000000082 nuclear magnetons, the unit typically used to measure this property. The magnetic moment, a property of particles that gives rise to magnetism, is one of the fundamental properties of the proton and is key to understanding properties such as the structure of atoms.

  • First light for the pioneering SESAME light source

    At 10:50 yesterday morning scientists at the pioneering SESAME light source saw First Monochromatic Light through the XAFS/XRF (X-ray absorption fine structure/X-ray fluorescence) spectroscopy beamline, signalling the start of the laboratory's experimental programme. This beamline, SESAME's first to come on stream, delivers X-ray light that will be used to carry out research in areas ranging from solid state physics to environmental science and archaeology.

  • Physicists develop faster way to make Bose-Einstein condensates

    The world of an atom is one of random chaos and heat. At room temperatures, a cloud of atoms is a frenzied mess, with atoms zipping past each other and colliding, constantly changing their direction and speed.

  • Designing new metal alloys using engineered nanostructures

    Materials science is a field that Jason Trelewicz has been interested in since he was a young child, when his father—an engineer—would bring him to work. In the materials lab at his father's workplace, Trelewicz would use optical microscopes to zoom in on material surfaces, intrigued by all the distinct features he would see as light interacted with different samples.

  • Quantum internet goes hybrid

    In a recent study published in Nature, ICFO researchers led by ICREA Prof. Hugues de Riedmatten report an elementary "hybrid" quantum network link and demonstrate photonic quantum communication between two distinct quantum nodes placed in different laboratories, using a single photon as information carrier.

  • Lightning, with a chance of antimatter

    A storm system approaches: the sky darkens, and the low rumble of thunder echoes from the horizon. Then without warning... Flash! Crash!—lightning has struck.

  • How the Earth stops high-energy neutrinos in their tracks

    Neutrinos are abundant subatomic particles that are famous for passing through anything and everything, only very rarely interacting with matter. About 100 trillion neutrinos pass through your body every second. Now, scientists have demonstrated that the Earth stops energetic neutrinos—they do not go through everything. These high-energy neutrino interactions were seen by the IceCube detector, an array of 5,160 basketball-sized optical sensors deeply encased within a cubic kilometer of very clear Antarctic ice near the South Pole.

  • ID microstructure of stock useful in financial crisis

    Every day, thousands of orders for selling or buying stocks are registered and processed within milliseconds. Electronic stock exchanges, such as NASDAQ, use what is referred to as microscopic modelling of the order flow - reflecting the dynamics of order bookings - to facilitate trading. The study of such market microstructures is a relatively new research field focusing on the trading interactions that determine the stock price.

  • Droplet explosion by shock waves, relevant to nuclear medicine

    An arrow shooting through an apple, makes for a spectacular explosive sight in slow motion. Similarly, energetic ions passing through liquid droplets induce shock waves, which can fragment the droplets.

  • Physicists open the door to the first direct measurement of Berry curvature in solid matter

    Berry curvature may not be the most well-known scientific concept, but to many physicists, its direct measurement is something akin to a holy grail.

  • New step towards future complex oxide electronics

    Researchers from TU Delft, Cornell University and the University of Cagliari report an interesting method for turning a highly insulating material into a highly conducting system. The process involves combining three different metal oxides in a sharp interface. They have recently published their findings in ACS Applied Materials & Interfaces.

  • Quantum optics offers alternative to expensive lasers in spectroscopy

    An international research group, together with scientists from the MSU, have developed a time-resolved spectroscopy method that allows studying fast processes in samples. The new method works by analyzing quantized light transmitted through a sample without the use of femtosecond lasers and complex detection systems. This design is much cheaper than the one used currently, and allows researchers to study a sample without destroying it. The research has been published in Scientific Reports.

  • Study shows how to get sprayed metal coatings to stick

    When bonding two pieces of metal, either the metals must melt a bit where they meet or some molten metal must be introduced between the pieces. A solid bond then forms when the metal solidifies again. But researchers at MIT have found that in some situations, melting can actually inhibit metal bonding rather than promote it.

  • PPPL scientists deliver new high-resolution diagnostic to national laser facility

    Scientists from the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have built and delivered a high-resolution X-ray spectrometer for the largest and most powerful laser facility in the world. The diagnostic, installed on the National Ignition Facility (NIF) at the DOE's Lawrence Livermore National Laboratory, will analyze and record data from high-energy density experiments created by firing NIF's 192 lasers at tiny pellets of fuel. Such experiments are relevant to projects that include the U.S. Stockpile Stewardship Program, which maintains the U.S. nuclear deterrent without full-scale testing, and to inertial confinement fusion, an alternative to the magnetic confinement fusion that PPPL studies.

  • Imaging technique unlocks the secrets of 17th century artists

    The secrets of 17th century artists can now be revealed, thanks to 21st century signal processing. Using modern high-speed scanners and the advanced signal processing techniques, researchers at the Georgia Institute of Technology are peering through layers of pigment to see how painters prepared their canvasses, applied undercoats, and built up layer upon layer of paint to produce their masterpieces.

  • 'Brazil nut effect' helps explain how rivers resist erosion, team finds

    Pop the top off a can of mixed nuts and, chances are, Brazil nuts will be at the top. This phenomenon, of large particles tending to rise to the top of mixtures while small particles tend to sink down, is popularly known as the "Brazil nut effect" and more technically as granular segregation.

  • How disposable diapers can improve measurements of tumor growth

    Catching cancer early can make all the difference for successful treatment. A common screening practice measures tumor growth with X-ray computed tomography (CT), which takes a series of cross-section images of the body.
