High-performance networks speed data on explosion's early discovery A recent discovery by scientists at the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley, of a supernova within hours of its explosion was made possible by a specialized telescope, state-of-the-art computational tools — and the high-speed data transmissions network of UC San Diego's High-Performance Wireless and Research Education Network (HPWREN), as well as the...

Berkeley Lab scientists demonstrate a tunable graphene device, the first tool in a kit for putting terahertz light to work Long-wavelength terahertz light is invisible — it's at the farthest end of the far infrared — but it's useful for everything from detecting explosives at the airport to designing drugs to diagnosing skin cancer. Now, for the first time, scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of...

  Berkeley Lab researchers develop inexpensive technique for making high quality nanowire solar cells Solar or photovoltaic cells represent one of the best possible technologies for providing an absolutely clean and virtually inexhaustible source of energy to power our civilization. However, for this dream to be realized, solar cells need to be made from inexpensive elements using low-cost, less energy-intensive processing chemistry, and they need to efficiently and...

  A team of scientists has discovered a supernova closer to Earth than any of its kind in a generation. Astronomers believe the supernova they caught, which is about 21 million light years away from Earth, is just within hours of its explosion. Scientists around the world are scrambling to observe it with as many telescopes as possible, including the Hubble Space Telescope.  Andy Howell, adjunct professor of physics at University of California - Santa Barbara (UCSB) and...

Ability to probe deep below material surfaces should be boon for nanoscale devices The expression "beauty's only skin-deep" has often been applied to the chemistry of materials because so much action takes place at the surface. However, for many of the materials in today's high technologies, such as semiconductors and superconductors, once a device is fabricated it is the electronic structures below the surface, in the bulk of the material or in buried layers, that determine its...

Berkeley Lab Researchers Develop Technique for Dynamically Controlling Plasmonic Airy Beams One of the earliest lessons in science that students learn is that a ray or beam of light travels in a straight line. Students also learn that light rays fan out or diffract as they travel. Recently it was discovered that light rays can travel without diffraction in a curved arc in free space. These rays of light were dubbed "Airy beams," after the English astronomer Sir George Biddell Airy, who...

Scientists at Berkeley Lab find nanoparticle size is readily controlled to make stronger aluminum alloys Long before they knew they were doing it "“ as long ago as the Wright Brother's first airplane engine "“ metallurgists were incorporating nanoparticles in aluminum to make a strong, hard, heat-resistant alloy. The process is called solid-state precipitation, in which, after the melt has been quickly cooled, atoms of alloying metals migrate through a solid matrix and gather...

Berkeley Lab researchers create graphene nanocomposite for high energy storage Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have created a graphene and tin nanoscale composite material for high-capacity energy storage in renewable lithium ion batteries. By encapsulating tin between sheets of graphene, the researchers constructed a new, lightweight "sandwich" structure that should bolster battery performance. "For an electric vehicle,...

Scientists with Berkeley Lab and Einstein College of Medicine Extend Conventional Click Chemistry to Living Cells Biomolecular imaging can reveal a great deal of information about the inner workings of cells and one of the most attractive targets for imaging are glycans "“ sugars that are ubiquitous to living organisms and abundant on cell surfaces. Imaging a glycan requires that it be tagged or labeled. One of the best techniques for doing this is a technique called click chemistry....


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
