  • Another ugly reminder to check your Facebook settings ? NOW!

    Hey you! Don't be blind to your Facebook privacy settings! Adjust them now! Do it! Do as I say! Obey me!If we take any lesson from this latest Facebook privacy brouhaha, it's one we should have already learned: Facebook isn't for people who don't wish to be known. Because here's the deal: Facebook has not now, nor will it ever, protect your information for you.


  • Cosmic Log: $1.4 million for oil cleanup ideas

  • Google: China blockage report likely just a glitch
    Google says its search engine and several other services are working normally in mainland China after previously reporting the service had been completely blocked.
  • 100 million Facebook users' details published online

    Screen capture of Facebook directory downloadThe personal details of 100 million Facebook users have been collected and published online in a downloadable file, meaning they will no longer be able to make the information private.


  • BlackBerry may be berry good with new OS

    BlackBerry's new OS 6 lets you see the day's appointments, most recent messages, e-mails and notifications from Facebook and Twitter.A new BlackBerry, but more importantly, a new BlackBerry operating system upgrade, is coming. "Yawn," you say? Don't be too quick to dismiss Research In Motion and its sturdy line of smart phones.

  • Graphene exhibits bizarre new behavior well suited to electronic devices
    Graphene, a sheet of pure carbon, has been touted as a possible replacement for silicon-based semiconductors because of its useful electronic properties. Now, physicists have shown that graphene has another unique and amazing property that could make it even more suitable for future electronic devices. When contorted in a specific way it sprouts nanobubbles in which electrons behave as if they are moving in a strong magnetic field.
  • Quantum fractals at the border of magnetism
    Physicists are reporting new results from experiments on the perplexing class of materials that includes high-temperature superconductors. The team reports the unexpected discovery of a simple fractal form of electronic excitations in ultra-low-temperature quantum magnets at the border of magnetism.
  • Behind the secrets of silk lie high-tech opportunities
    Tougher than a bullet-proof vest yet synonymous with beauty and luxury, silks spun by worms and spiders are a masterpiece of nature whose properties have yet to be fully replicated in the laboratory. But scientists have begun to unravel the secrets of silk. Biomedical engineers report that silk-based materials have been transformed from commodity textile to a growing web of high tech applications.
  • Hexagonal boron nitride sheets may help graphene supplant silicon
    What researchers might call "white graphene" may be the perfect sidekick for the real thing as a new era unfolds in nanoscale electronics. Researchers have figured out how to make sheets of h-BN, which could turn out to be the complementary apple to graphene's orange.
  • First step toward electronic DNA sequencing: Translocation through graphene nanopores
    Researchers have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules. Using electric fields, the tiny DNA strands are pushed through nanoscale-sized thin pores in a graphene nanopore platform that ultimately may be important for fast electronic sequencing of the four chemical bases of DNA based on their unique electrical signature.
  • Radical new computer memory? Emergent resistance network suggests mechanism for colossal magnetoresistance
    Research has revealed new clues on the microscopic processes by which resistance in certain materials is dramatically altered by the presence of magnetic fields. The discovery provides fundamental insights toward the development of radically new memory and switching devices.
  • Cheaper substrates made of oxide materials
    Imagine building cheaper electronics on a variety of substrates -- materials like plastic, paper, or fabric. Researchers in Taiwan have made a discovery that opens this door, allowing them to build electronic components like diodes on many different substrates.
  • An alchemist?s dream: Lead-free electronics
    It?s been said that the typical mobile phone contains roughly half of all elements found on the Periodic Table. One of the most problematic substances used in phones and other electronics is lead. But making lead-free electronics has proved problematic ? until now. Researchers have now developed a method that enables the industrial production of a substance that can be used to replace lead in many electronic applications.
  • Organic nanoelectronics a step closer
    Scientists have effectively discovered a way to order the molecules in the PEDOT, the single most industrially important conducting polymer.
  • Nanowick at heart of new system to cool 'power electronics'
    Researchers have shown that an advanced cooling technology being developed for high-power electronics in military and automotive systems is capable of handling roughly 10 times the heat generated by conventional computer chips.
