New Scientist TV: Hack your hand to learn the guitar - 0 views

  •  
    Instead of practicing for hours, a device can now teach you a tune by taking control of your hand (see video above). The system, developed by the University of Tokyo and Sony Computer Science Laboratories, is appropriately named PossessedHand and electrically stimulates muscles in your arm that move your fingers. Tests have shown that the device can help you learn the correct fingering faster but many find the concept unsettling. Would you be willing to have your hand hacked to learn an instrument?

Stressed-DNA repair protein identified | KurzweilAI - 0 views

  •  
    Vera Gorbunova and Andrei Seluanov of the University of Rochester have found that human cells undergoing oxidative stress caused by environmental chemicals or routine cellular processes produce a protein (SIRT6) that stimulates cells to repair DNA double-strand breaks, thought to be associated with premature aging and cancer. The team first measured levels of SIRT6 in stressed cells, then treated a second group of stressed cells with a drug that deactivates the protein. DNA repair in the second group stopped, confirming SIRT6′s role.  The team also found that SIRT6 acts in concert with another protein, called PARP1, to make the repairs. Furthermore, the team found that increased levels of SIRT6 lead to faster DNA repair. They suspect that the protein acts as a "master regulator," coordinating stress and DNA repair activities.

Mind-reading scan identifies simple thoughts - health - 26 May 2011 - New Scientist - 0 views

  •  
    A new new brain imaging system that can identify a subject's simple thoughts may lead to clearer diagnoses for Alzheimer's disease or schizophrenia - as well as possibly paving the way for reading people's minds. Michael Greicius at Stanford University in California and colleagues used functional magnetic resonance imaging (fMRI) to identify patterns of brain activity associated with different mental states. He asked 14 volunteers to do one of four tasks: sing songs silently to themselves; recall the events of the day; count backwards in threes; or simply relax. Participants were given a 10-minute period during which they had to do this. For the rest of that time they were free to think about whatever they liked. The participants' brains were scanned for the entire 10 minutes, and the patterns of connectivity associated with each task were teased out by computer algorithms that compared scans from several volunteers doing the same task. This differs from previous experiments, in which the subjects were required to perform mental activities at specific times and the scans were then compared with brain activity when they were at rest. Greicius reasons his method encourages "natural" brain activity more like that which occurs in normal thought.

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.

DNA can discern between two quantum states, research shows - 0 views

  •  
    ScienceDaily (June 4, 2011) - Do the principles of quantum mechanics apply to biological systems? Until now, says Prof. Ron Naaman of the Institute's Chemical Physics Department (Faculty of Chemistry), both biologists and physicists have considered quantum systems and biological molecules to be like apples and oranges. But research he conducted together with scientists in Germany, which appeared recently in Science, shows that a biological molecule -- DNA -- can discern between quantum states known as spin.

Researchers create light from 'almost nothing' - 0 views

  •  
    (PhysOrg.com) -- A group of physicists working out of Chalmers University of Technology in Gothenburg, Sweden, have succeeded in proving what was until now, just theory; and that is, that visible photons could be produced from the virtual particles that have been thought to exist in a quantum vacuum. In a paper published on arXiv, the team describes how they used a specially created circuit called a superconducting quantum interference device (SQUID) to modulate a bit of wire length at a roughly five percent of the speed of light, to produce visible "sparks" from the nothingness of a vacuum.

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

The Public Values Failures of Climate Science in the US by Ryan Meyer - Minerva, Volume... - 0 views

  •  
    "This paper examines the broad social purpose of US climate science, which has benefited from a public investment of more than $30 billion over the last 20 years. A public values analysis identifies five core public values that underpin the interagency program. Drawing from interviews, meeting observations, and document analysis, I examine the decision processes and institutional structures that lead to the implementation of climate science policy, and identify a variety of public values failures accommodated by this system. In contrast to other cases which find market values frameworks (the "profit as progress" assumption) at the root of public values failures, this case shows how "science values" ("knowledge as progress") may serve as an inadequate or inappropriate basis for achieving broader public values. For both institutions and individual decision makers, the logic linking science to societal benefit is generally incomplete, incoherent, and tends to conflate intrinsic and instrumental values. I argue that to be successful with respect to its motivating public values, the US climate science enterprise must avoid the assumption that any advance in knowledge is inherently good, and offer a clearer account of the kinds of research and knowledge advance likely to generate desirable social outcomes.

Technology: Necessary but Insufficient for Human Survival | Thinkahol's Blog - 0 views

  •  
    In the context of technology the only way out is through. Global society is dependent on artificially inflated energy resources-i.e. oil-that are directly leading us toward total collapse. Technology is being used to most efficiently maximize wealth of the largest corporate conglomerates at the expense of the social fabric and a living environment. The biosphere is in fact collapsing. The technology exists to solve our technical problems but the solutions do not seem like they will be effectively put to use. The power structures concentrating money off the status quo are too entrenched. Each human is called on to become more aware.
