    Updated: 2011-10-31 08:03:15
    Michael Underwood captured this amazing image of the Milky Way outside of Lake City, Colorado on July 2, 2011. This is certainly a stunning view while driving! Michael used a Nikon D7000 camera with Nikon 14-24mm lens. He also provided us with a few technical details of the image. Exposure- 30 seconds Aperture- f/2.8 Focal [...]

  • Scientists still seek explanation for faster-than-light neutrino result

    Updated: 2011-10-28 12:24:30
    The question of whether the OPERA experiment's faster-than-light neutrino measurement is correct is still up in the air, despite what some headlines have suggested. Experimentalists have not been able to establish how the experiment is flawed, and yet theorists have not been able to determine how its conclusion could be true.

  • Advancements in proton therapy cause for celebration

    Updated: 2011-10-21 15:43:14
    In 1946, founding Fermilab director Robert Wilson was one of the first to tout the benefits of proton therapy. The cancer treatment has since been lauded as a way to minimize damage to healthy tissue while focusing a finely calibrated beam directly on the tumor – an impossibility for radiation treatments based on X-rays or gamma rays. Yet protons were not used within a hospital facility until 1990 with Fermilab’s construction of a particle accelerator at Loma Linda University Medical Center. Since then, the industry has grown and the technology has evolved. Worldwide, 37 centers use proton therapy and more than 73,000 patients have been treated.

  • LAGUNA large neutrino observatory design moves forward

    Updated: 2011-10-18 20:00:45
    The kick-off meeting for the second phase of the LAGUNA's design study starts today at CERN. The principal goal of LAGUNA (Large Apparatus for Grand Unification and Neutrino Astrophysics) is to assess the feasibility of a new pan-European research infrastructure able to host the next generation, very large volume, deep underground neutrino observatory. The scientific goals of such an observatory combine exciting neutrino astrophysics with research addressing several fundamental questions such as proton decay and the existence of a new source of matter-antimatter asymmetry in Nature, in order to explain why our Universe contains only matter and not equal amounts of matter and antimatter.

  • Bubble chamber gets more precise in dark matter search

    Updated: 2011-10-14 17:12:44
    The 1970s were a thriving time in the world of physics, heralding such milestones as the development of the Standard Model and the discovery of the bottom quark. Now scientists at Fermilab are bringing some experimental pieces of that era back – bubble chambers and fixed-target physics. Peter Cooper, a Fermilab physicist, is heading a new experiment calibrating the classic bubble chamber technology, which is used today to search for dark matter.

  • Twisting Radio Waves Could Give Us 100x More Wireless Bandwidth | DISCOVER Magazine

    Updated: 2011-10-10 19:25:00
    As more people stream video to their mobile devices, wireless bandwidth is becoming an increasingly precious commodity. Data traffic increased 8,000 percent in the past four years on AT&T’s network alone. In trying to avoid what the Federal Communications Commission calls a “looming spectrum crisis,” telecommunications companies are lobbying the government to assign them more spectrum space in the 300- to 3,000-megahertz range, the sweet spot for wireless communication. But Italian astrophysicist Fabrizio Tamburini says a solution may lie in making better use of the frequencies already in use. In a recent paper, he demonstrated a potential way to squeeze 100 times more bandwidth out of existing frequencies. The idea is to twist radio waves like corkscrews and create multiple subfrequencies, distinguished by their degree of twistedness. Each subchannel carries discrete data sets. “You can tune the wave with a given frequency as you normally do, but there is also a fingerprint left by the twist,” Tamburini says...

  • Physicists discover 'magnetotoroidic effect'

    Updated: 2011-09-26 14:10:01
    (PhysOrg.com) -- For many years, scientists have known about the magnetoelectric effect, in which an electric field can induce and control a magnetic field, and vice versa. In this effect, the electric field has always been homogeneous. Now, scientists have found that a curled electric field can also be used to control magnetic fields, constituting a novel phenomenon that they call the "magnetotoroidic effect."

  • Could primordial black holes be dark matter?

    (PhysOrg.com) -- “We know that about 25% of the matter in the universe is dark matter, but we don’t know what it is,” Michael Kesden tells PhysOrg.com. “There are a number of different theories about what dark matter could be, but we think one alternative might be very small primordial black holes.”
