Scientists report first solar cell producing more electrons in photocurrent than solar ... - 0 views

  •  
    (PhysOrg.com) -- Researchers from the National Renewable Energy Laboratory (NREL) have reported the first solar cell that produces a photocurrent that has an external quantum efficiency greater than 100 percent when photoexcited with photons from the high energy region of the solar spectrum

Erasing signs of aging in human cells now a reality - 1 views

  •  
    ScienceDaily (Nov. 3, 2011) - Scientists have recently succeeded in rejuvenating cells from elderly donors (aged over 100). These old cells were reprogrammed in vitro to induced pluripotent stem cells (iPSC) and to rejuvenated and human embryonic stem cells (hESC): cells of all types can again be differentiated after this genuine "rejuvenation" therapy. The results represent significant progress for research into iPSC cells and a further step forwards for regenerative medicine.

Microsoft offers a glimpse into the future of productivity | KurzweilAI - 1 views

  •  
    Microsoft has posted an awesome new concept video with some ubercool new interfaces that could be here in five to ten years, estimates Kurt DelBene, President, Microsoft Office Division.
    That sounds a bit conservative. "All of the ideas in the video are based on real technology," he said. "Some of the capabilities, such as speech recognition, real time collaboration, and data visualization, already exist today. Others are not yet available in specific products, but represent active research and development happening at Microsoft and other companies."
    "Other companies" … hmm, some of the concepts look a bit like Nokia's visionary Morph concept tech  (see the video at the bottom of this post and our 2010 news item).

Lasers could power drones in flight or launch rockets | KurzweilAI - 0 views

  •  
    Researchers at LaserMotive have devised a way to beam lasers to power military bases and drones, possibly helping to save lives, since delivering fuel to battle zones can be a dangerous task in wartime.
    Although still largely in the R&D stage, laser power beaming has many other potential uses, which include powering vehicles, replacing electric power wiring and transmission lines in difficult places, and even launching rockets into orbit.
    The beam is about 8 inches wide as it leaves the transmitter - and then spreads wider as it travels. The beam emitter is located at a ground-based unit and operated by a person, who could control it from the same location or remotely from an entirely different place altogether.
    The operator uses the machine to fire the laser beam at a photovoltaic collector located on an unmanned autonomous vehicle (UAV), small plane, or helicopter. The current range of the system is about a kilometer.
    When the laser hits the photovoltaic device, the photons in the light beam are converted to electricity to fly the AUV.

‪Michael Pawlyn: Using nature's genius in architecture‬‏ - YouTube - 0 views

  •  
    http://www.ted.com How can architects build a new world of sustainable beauty? By learning from nature. At TEDSalon in London, Michael Pawlyn describes three habits of nature that could transform architecture and society: radical resource efficiency, closed loops, and drawing energy from the sun.

    TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes. Featured speakers have included Al Gore on climate change, Philippe Starck on design, Jill Bolte Taylor on observing her own stroke, Nicholas Negroponte on One Laptop per Child, Jane Goodall on chimpanzees, Bill Gates on malaria and mosquitoes, Pattie Maes on the "Sixth Sense" wearable tech, and "Lost" producer JJ Abrams on the allure of mystery. TED stands for Technology, Entertainment, Design, and TEDTalks cover these topics as well as science, business, development and the arts. Closed captions and translated subtitles in a variety of languages are now available on TED.com, at http://www.ted.com/translate.

Historic first images of rod photoreceptors in the living human eye - 0 views

  •  
    ScienceDaily (June 9, 2011) - Scientists have just reported that the tiny light-sensing cells known as rods have been clearly and directly imaged in the living eye for the first time. Using adaptive optics (AO), the same technology astronomers use to study distant stars and galaxies, scientists can see through the murky distortion of the outer eye, revealing the eye's cellular structure with unprecedented detail. This innovation, described in two papers in the Optical Society's (OSA) open access journal Biomedical Optics Express, will help doctors diagnose degenerative eye disorders sooner, leading to quicker intervention and more effective treatments.

GE Sees Solar Cheaper Than Fossil Power in Five Years - 0 views

  •  
    Once you include the subsidies* given to fossil fuel providers, solar is ALREADY cheaper!

    *The subsidies give to fossil fuel providers include multiple dumbass wars for oil, drilling/mining on federal lands, environmental damage (think climate change, oil spills, mountain top removal, drinking water contamination, etc.), etc
