"Brazil has done more than any other country over the past five years to cut global warming emissions by dramatically reducing its deforestation. Destroying tropical forests is responsible for about 15 percent of global warming pollution, and Brazil had been the biggest source of deforestation pollution. Its reduction is a stunning turnaround.

WASHINGTON - A black sealant sprayed on parking lots, driveways and playgrounds turns out to be the largest contributor to the rise of a toxic pollutant in urban lakes and reservoirs across America, according to a new U.S. Geological Survey study.

WikiLeaks is again publishing a trove of documents, in this case classified U.S. State Department diplomatic cables. The whistle-blower website will gradually be releasing more than 250,000 of these documents in the coming months so that they can be analyzed and gain the attention they deserve. The cables are internal, written communications among U.S. embassies around the world and also to the U.S. State Department. WikiLeaks described the leak as "the largest set of confidential documents ever to be released into the public domain [giving] an unprecedented insight into U.S. government foreign activities."

ScienceDaily (Dec. 3, 2010) - IBM scientists have unveiled a new chip technology that integrates electrical and optical devices on the same piece of silicon, enabling computer chips to communicate using pulses of light (instead of electrical signals), resulting in smaller, faster and more power-efficient chips than is possible with conventional technologies.

some researchers at the MIT Media Lab are aiming to put the controls back in people's hands, in a way that provides sophisticated and continuous control and could slash lighting bills by more than half.

This method may potentially be suitable for designing novel light sources resembling lasers that work in the x-ray range. Among other applications, they might allow building more powerful computer chips.

The layout of the interior spaces and the distribution of opaque and glazed cladding surfaces are optimized for minimal energy loss, maximum natural daylighting, and selective solar gain. This energy optimization combined with extensive building integration of photovoltaic and solar thermal systems allow the house to produce a net annual surplus of energy, more than is needed to supply the house and its electric vehicles.

The SAO/NASA Astrophysics Data System (ADS) is a Digital Library portal for researchers in Astronomy and Physics, operated by the Smithsonian Astrophysical Observatory (SAO) under a NASA grant. The ADS maintains three bibliographic databases containing more than 6.9 million records: Astronomy and Astrophysics, Physics, and arXiv e-prints. The main body of data in the ADS consists of bibliographic records, which are searchable through highly customizable query forms, and full-text scans of much of the astronomical literature which can be browsed or searched via our full-text search interface. Integrated in its databases, the ADS provides access and pointers to a wealth of external resources, including electronic articles, data catalogs and archives. We currently have links to over 7.6 million records maintained by our collaborators.

Midwest Junto for the History of Science more than a half century ago to provide a professional forum for themselves, students and like-minded individuals unable to afford travel to a national professional meeting.

How do we relate human thought processes to measurable events in the brain? Mental chronometry, which has origins that date back more than a century, seeks to measure the time course of mental operations in the human nervous system [1]. From the late 1800s until 1950, the field was built almost entirely around a single method: measuring and comparing people's reaction times during simple cognitive tasks.

Apomediation is a new scholarly socio-technological term that characterizes the process of disintermediation (intermediaries are middlemen or "gatekeeper", e.g. health professionals giving "relevant" information to a patient, and disintermediation means to bypass them), whereby the former intermediaries are functionally replaced by apomediaries, i.e. network/group/collaborative filtering processes [Eysenbach, 2008 [WebCite] and 2007b]. The difference between an intermediary and an apomediary is that an intermediary stands "in between" (latin: inter- means "in between") the consumer and information/service, i.e. is absolutely necessary to get a specific information/service. In contrast, apomediation means that there are agents (people, tools) which "stand by" (latin: apo- means separate, detached, away from) to guide a consumer to high quality information/services/experiences, without being a prerequisite to obtain that information/service in the first place. The switch from an intermediation model to an apomediation model has broadimplications for example for the way people judge credibility, as hypothesized and elaborated in more detail elsewhere [

But the tab as an information technology metaphor is everywhere in use. And whether our tabs are cardboard extensions or digital projections, they all date to an invention little more than a hundred years old. The original tab signaled an information storage revolution and helped enable everything from management consulting to electronic data processing.

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.

Everyone has experienced a broken knob or a broken piece off of an appliance. You also know that while trying to get a new one you might have a long waiting period. Well there might be a prototype that is here to solve that problem. The Thing-O-Matic claims to manifest any three-dimensional plastic object in just minutes. The machine was shown first at a Las Vegas trade fair and is meant to make manufacturing more common for the average person.\n\n3,000 have already been sold at $790 a device. This model only makes plastic objects but the manufacturers say that in the future models could make metal and plastic models to make super cool gadgets. The machines make objects that are six by six by seven inches. The machine is not capable of making images but it does make boxes, tubes and get this- even action figures!

ScienceDaily (Jan. 6, 2011) - For parents wanting to reduce the negative influence of TV on their children, the first step is normally to switch off the television set. But a new study suggests that might not be enough. It turns out indirect media exposure, i.e., having friends who watch a lot of TV, might be even more damaging to a teenager's body image.

"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.

ScienceDaily (Mar. 7, 2011) - Despite the fears of some, a new study suggests that use of the internet in general does not make people more likely to believe political rumors.

"Let me now express my position more clearly and systemically: philosophy of science can seek to generate scientific knowledge in places where science itself fails to do so; I call this the complementary function of philosophy of science, as opposed to its descriptive and prescriptive functions. I propose taking the philosophy of science as a field which investigates scientific questions that are not addressed in current specialist science - questions that could be addressed by scientists, but are excluded due to the necessities of specialization."

Catch a first-time glimpse at smart technology that will put android helpers in the home, network commuters and entire cities to the Web, and bring us entertainment systems that can virtually make dreams come true. Advances in artificial intelligence are creating machines with near human-like mental agility. Intelligence will be embedded everywhere - even in our clothing, thanks to smaller, more powerful computers. Soon, we will be able to build computers with artificial intelligence and processing power that rivals the human brain. Intelligence will be everywhere, in our clothing, our vehicles and homes. Intelligent robots will serve us - until they don't feel like doing so anymore. And what happens then…?

RepRap is a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap can print those parts, RepRap is a self-replicating machine - one that anyone can build given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend...RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. We are using 3D printing to do this, but if you have other technologies that can copy themselves and that can be made freely available to all, then this is the place for you too.Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. Our community portal and New Development pages have more information on how to get involved. Use the links below and on the left to explore the site contents.
