Digital Public Library of America - 0 views

  •  
    The vision of a national digital library has been circulating among librarians, scholars, educators, and private industry representatives since the early 1990s, but it has not yet materialized. Efforts led by a range of organizations, including the Library of Congress, HathiTrust, and the Internet Archive, have successfully built resources that provide books, images, historical records, and audiovisual materials to anyone with Internet access. Many universities, public libraries, and other public-spirited organizations have digitized materials that could be brought together under the frame of the DPLA, but these digital collections often exist in silos.

Math Does Not Equal Calculating: Using Computer-Based Math Education - 0 views

  •  
    "computerbasedmath.org is the project to perform this reset. We're building a completely new math curriculum with computer-based computation at its heart, while campaigning at all levels to redefine math education away from historical hand-calculating techniques and toward real-life problem-solving situations that drive high-concept math understanding and experience."

SGI Wikipedia Project - 0 views

  •  
    He turned to Wikipedia and together with SGI has created the first-ever historical mapping and exploration of the full text contents of the English-language edition of Wikipedia, in time and space, with visualizations of modern history captured in under a day. Loading the entire English language edition of Wikipedia into SGI UV 2000, Mr. Leetaru was able to show how Wikipedia's view of the world unfolded over the past two centuries. Location, year and the positive or negative sentiment have been tied to those references.

Scientists reveal driving force behind evolution - 0 views

  • The team observed viruses as they evolved over hundreds of generations to infect bacteria. They found that when the bacteria could evolve defences, the viruses evolved at a quicker rate and generated greater diversity, compared to situations where the bacteria were unable to adapt to the viral infection. The study shows, for the first time, that the American evolutionary biologist Leigh Van Valen was correct in his 'Red Queen Hypothesis'. The theory, first put forward in the 1970s, was named after a passage in Lewis Carroll's Through the Looking Glass in which the Red Queen tells Alice, 'It takes all the running you can do to keep in the same place'. This suggested that species were in a constant race for survival and have to continue to evolve new ways of defending themselves throughout time. Dr Steve Paterson, from the University's School of Biosciences, explains: "Historically, it was assumed that most evolution was driven by a need to adapt to the environment or habitat. The Red Queen Hypothesis challenged this by pointing out that actually most natural selection will arise from co-evolutionary interactions with other species, not from interactions with the environment. "This suggested that evolutionary change was created by 'tit-for-tat' adaptations by species in constant combat. This theory is widely accepted in the science community, but this is the first time we have been able to show evidence of it in an experiment with living things." Dr Michael Brockhurst said: "We used fast-evolving viruses so that we could observe hundreds of generations of evolution. We found that for every viral strategy of attack, the bacteria would adapt to defend itself, which triggered an endless cycle of co-evolutionary change. We compared this with evolution against a fixed target, by disabling the bacteria's ability to adapt to the virus. "These experiments showed us that co-evolutionary interactions between species result in more genetically diverse populations, compared to instances where the host was not able to adapt to the parasite. The virus was also able to evolve twice as quickly when the bacteria were allowed to evolve alongside it."

    Scientists at the University of Liverpool have provided the first experimental evidence that shows that evolution is driven most powerfully by interactions between species, rather than adaptation to the environment.
