Invention regulates nerve cells electronically - 0 views

  •  
    ScienceDaily (May 22, 2010) - A major step toward being able to regulate nerve cells externally with the help of electronics has been taken by researchers at Linköping University and the Karolinska Institute in Sweden. The breakthrough is based on an ion transistor of plastic that can transport ions and charged biomolecules and thereby address and regulate cells.

Medical Daily: UVic biomedical engineer 'outsmarts' HIV - 0 views

  •  
    Willerth and her team studied approximately 15,000 different versions of the virus-something that has never been done before. This information has allowed them to locate the specific genes of the virus that were resistant to the drugs-knowledge that could ultimately help researchers develop more effective treatments for HIV.

Advance in Quantum Computing Entangles Particles by the Billions - NYTimes.com - 0 views

  •  
    In a step toward a generation of ultrafast computers, physicists have used bursts of radio waves to briefly create 10 billion quantum-entangled pairs of subatomic particles in silicon. The research offers a glimpse of a future computing world in which individual atomic nuclei store and retrieve data and single electrons shuttle it back and forth.

The Professional and the Scientist in Nineteenth-Century America - JSTOR: Isis, Vol. 10... - 0 views

  •  
    "In nineteenth‐century America, there was no such person as a "professional scientist." There were professionals and there were scientists, but they were very different. Professionals were men of science who engaged in commercial relations with private enterprises and took fees for their services. Scientists were men of science who rejected such commercial work and feared the corrupting influences of cash and capitalism. Professionals portrayed themselves as active and useful members of an entrepreneurial polity, while scientists styled themselves as crusading reformers, promoters of a purer science and a more research‐oriented university. It was this new ideology, embodied in these new institutions, that spurred these reformers to adopt a special name for themselves-"scientists." One object of this essay, then, is to explain the peculiar Gilded Age, American origins of that ubiquitous term. A larger goal is to explore the different social roles of the professional and the scientist. By attending to the particular vocabulary employed at the time, this essay tries to make clear why a "professional scientist" would have been a contradiction in terms for both the professional and the scientist in nineteenth‐century America.

  • Throughout history, meaningful contributions to science have been made by members of the public. These citizen scientists have historically contributed by collecting data that is hard for a single scientist to collect such as weather information or the paths of migrating birds. Recently, advances in computer technology have opened new possibilities for citizen scientists to participate in science projects by helping with data analysis. We are investigating what motivates people to do this and what they learn when they do so. To do so, we are working with Galaxy Zoo and the Zooniverse family of citizen science projects.

  •  
    The important debate on global warming under UN auspices provides but a partial picture of climate change; in addition to the devastating impacts of greenhouse gas emissions on the ozone layer, the World's climate can now be modified as part of a new generation of sophisticated "non-lethal weapons." Both the Americans and the Russians have developed capabilities to manipulate the World's climate. In the US, the technology is being perfected under the High-frequency Active Aural Research Program (HAARP) as part of the ("Star Wars") Strategic Defence Initiative (SDI). Recent scientific evidence suggests that HAARP is fully operational and has the ability of potentially triggering floods, droughts, hurricanes and earthquakes.

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.

EPFL spinoff turns thousands of 2D photos into 3D images | KurzweilAI - 0 views

  •  
    Researchers in EPFL's Computer Vision Laboratory developed a computer-based modeling service that generates a 3D image from up to thousands of 2D shots, with all the processing done in the cloud. Since April, the EPFL startup Pix4D has been offering the modeling service with a fourth dimension: time. Now, individuals and small businesses looking for fast, cheap, large-scale 3D models can get them without investing in heavy processing, the company states. With Pix4D, users upload a series of photos of an object, and within 30 minutes they have a 3D image. The software defines "points of interest" from among the photos, or common points of high-contrast pixels. Next, the program pastes the images together seamlessly by matching up the points of interest. Much in the same way our two eyes work together to calculate depth, the software computes the distance and angle between two or more photos and lays the image over the model appropriately, creating a highly accurate 3D model that avoids the time intensive, "point by point" wireframe method. With Pix4D's 3D models, you can navigate in all directions as well as change the date on a timeline to see what a place looked like at different times of the year. The company is collaborating with several drone makers (including another EPFL startup,senseFly) to market their software as a package with senseFly's micro aerial vehicles, or autonomous drones. Pix4D's time element avoids waiting for Google to update its satellite data or for an expensive plane to fly by and take high-resolution photos. Farmers, for example, can now send relatively inexpensive flying drones into the air to take pictures as often as they like, allowing them to survey the evolution of their crops over large distances and long periods of time. And since the calculations are done on a cloud server, the client doesn't need a powerful computer of his or her own.

  •  
    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.

The BBC Trust Report on Science | through the looking glass - 0 views

  • Aside from questions over appropriateness of expertise being a rather slippery issue, there is very little information given about the expertise of a speaker. We found lot of reliance on phrases such as ‘scientists have found’ and ‘experts say’. Personally I think we need to address this issue before we can even get on to matters of whether experts are the right ones or not. Although expertise may be implied through editing, and TV in particular can flag up institutional association and title, we rarely saw a contributor’s disciplinary background specified. Especially significant I thought, in broadcast reports about new research we found little explicit reference to whether or not a particular contributor was involved in the research being reported (online reports often refer to someone as ‘lead author’ or ‘co-author’). This lack of definition makes it hard for audiences to judge a contributor’s independence, whether they are speaking on a topic they have studied in depth or if they are simply working from anecdote.
