  1. Quantum Holograms As Atomic Scale Memory Keepsake

    Russian scientists have developed a theoretical model of quantum memory for light, adapting the concept of a hologram to a quantum system. These findings from Anton Vetlugin and Ivan Sokolov from St. Petersburg State University in Russia are published in a study in EPJD.

  2. Physicists Build Reversible Laser Tractor Beam

    Laser physicists have built a tractor beam that can repel and attract objects, using a hollow laser beam that is bright around the edges and dark in its centre.

  3. Winning By Losing

    What started out as a mathematical oddity, has now become a new kind of laser technology. Two years ago, physicists at TU Wien predicted a paradoxical laser effect: Under certain conditions, a laser can be switched on not by supplying it with more energy, but by taking energy away from the laser.

  4. Natcore Technology Makes First Laser-Processed All-Low-Temperature Solar Cell

    Incorporating its proprietary advances in laser-processing technology, scientists at Natcore Technology (TSX-V: NXT; NTCXF.PK) have created an all-low-temperature, laser-processed solar cell.

  5. Materials For The Next Generation Of Electronics And Photovoltaics

    One of the longstanding problems of working with nanomaterials--substances at the molecular and atomic scale--is controlling their size. When their size changes, their properties also change.

  6. Olympus 3D Microscope Used To Recover Data From Damaged Optical Media

    The fields of Information Technology and Digital Forensics have encountered many situations where stored digital information is highly desired but its storage media has been severely damaged.

  7. Atom-Width Graphene Sensors Could Provide Unprecedented Insights Into Brain Structure And Function

    Understanding the anatomical structure and function of the brain is a longstanding goal in neuroscience and a top priority of President Obama’s brain initiative.

  8. Wearable Technologies Create New Opportunities, Raise Questions

    Visionaries driving next-generation wearable technology offered their insights on development challenges facing the technology -- and some concerns about its impacts -- in recent talks at SPIE Optics + Photonics 2014 and in interviews with SPIE, the international society for optics and photonics.

  9. OSA Kicks Off International Year Of Light Educational Efforts At Frontiers In Optics 2014

    The Optical Society (OSA) recently announced that its annual meeting, Frontiers in Optics (FiO) 2014, taking place next week in Tucson, Arizona, USA, will serve as the launch for its extensive educational outreach associated with the 2015 International Year of Light (IYL).

  10. Tiny "Nanoflares" Might Heat The Sun's Corona

    Today, a team led by Paola Testa of the Harvard-Smithsonian Center for Astrophysics (CfA) is presenting new clues to the mystery of coronal heating using observations from the recently launched Interface Region Imaging Spectrograph (IRIS). The team finds that miniature solar flares called "nanoflares" - and the speedy electrons they produce - might partly be the source of that heat, at least in some of the hottest parts of the Sun's corona.
