Why some genes are silenced: Researchers find clue as to how notes are played on the 'g... - 0 views

  •  
    ScienceDaily (May 13, 2011) - Japanese and U.S. scientists in the young field of epigenetics have reported a rationale as to how specific genes are silenced and others are not. Because this effect can be reversed, it may be possible to devise therapies for cancer and other diseases using this information.

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.

Stingy aliens may call us on cheap rates only - space - 21 July 2010 - New Scientist - 0 views

  •  
    A new study suggests that cost-effective galactic radio transmissions would be at higher frequencies than SETI projects traditionally monitor, and ET's attempts to make contact would be only few and far between. "If ET was building cost-effective beacons, would our searches have detected them? The answer turns out to be no," says James Benford, president of the company Microwave Sciences in Lafayette, California.

Progress toward terabit-rate high-density recording - 0 views

  •  
    Next-generation high-density storage devices may keep more than 70 times the contents of the entire US Library of Congress on a single disc -- but only if that data can be written quickly enough. In the Journal of Applied Physics, researchers in China have demonstrated a way to record onto ferromagnetic films thirty times faster than today's technologies.

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.
