Traces of the past: Computer algorithm able to 'read' memories - 0 views

  • To explore how such memories are recorded, the researchers showed ten volunteers three short films and asked them to memorise what they saw. The films were very simple, sharing a number of similar features - all included a woman carrying out an everyday task in a typical urban street, and each film was the same length, seven seconds long. For example, one film showed a woman drinking coffee from a paper cup in the street before discarding the cup in a litter bin; another film showed a (different) woman posting a letter. The volunteers were then asked to recall each of the films in turn whilst inside an fMRI scanner, which records brain activity by measuring changes in blood flow within the brain. A computer algorithm then studied the patterns and had to identify which film the volunteer was recalling purely by looking at the pattern of their brain activity. The results are published in the journal Current Biology. "The algorithm was able to predict correctly which of the three films the volunteer was recalling significantly above what would be expected by chance," explains Martin Chadwick, lead author of the study. "This suggests that our memories are recorded in a regular pattern." Although a whole network of brain areas support memory, the researchers focused their study on the medial temporal lobe, an area deep within the brain believed to be most heavily involved in episodic memory. It includes the hippocampus - an area which Professor Maguire and colleagues have studied extensively in the past. They found that the key areas involved in recording the memories were the hippocampus and its immediate neighbours. However, the computer algorithm performed best when analysing activity in the hippocampus itself, suggesting that this is the most important region for recording episodic memories. In particular, three areas of the hippocampus - the rear right and the front left and front right areas - seemed to be involved consistently across all participants. The rear right area had been implicated in the earlier study, further enforcing the idea that this is where spatial information is recorded. However, it is still not clear what role the front two regions play.

    Computer programs have been able to predict which of three short films a person is thinking about, just by looking at their brain activity. The research, conducted by scientists at the Wellcome Trust Centre for Neuroimaging at UCL (University College London), provides further insight into how our memories are recorded.

Synote Home Page - 0 views

  •  
    Synote makes multimedia resources such as video and audio easier to access, search, manage, and exploit. Learners, teachers and other users can create notes, bookmarks, tags, links, images and text captions synchronised to any part of a recording, such as a lecture. Imagine how difficult it would be to use a textbook if it had no contents page, index or page numbers. Synote actually provides the way to find or associate notes with a particular part of a recording,i.e. the media fragments.

Record Arctic Ice Melt Threatens Global Security - 0 views

    'It is now virtually certain a child born in 1979 will not reach 50 years of age before the Arctic is ice-free in the summer. That is a rapid change on a planetary scale, with far-reaching consequences that scientists are just beginning to understand.' Stephen Leahy, Inter Press Service

New Record For Most Distant Galaxy Cluster -- Space.com - 0 views

  •  
    The most distant known galaxy cluster has been discovered with NASA's Chandra X-ray Observatory. The cluster, known as JKCS041, is located about 10.2 billion light-years away and is observed as it was when the universe was only about a quarter of its present age. It beats the previous record holder, XMMXCS J2215.9-1738, by about a billion light-years.

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.

Daniel Mietchen Project: Communicating research as Beethoven suggested | RocketHub - 0 views

  •  
    "What are we aiming for? We want to change the way research is communicated, both amongst researchers, as well as with health practitioners, patients and the wider public. Inspired by Beethoven, we want to build a research version of his repository and try to tackle the question "What if the public scientific record would be updated directly as research proceeds?""

    "In short, this site is a record of my learning process as I try to understand aspects of colony health and productivity, and the reasons why various management techniques work (or don't). If you are a beginning beekeeper looking for basic information, or an experienced beekeeper looking for a summary of mite treatment options, I suggest that you go directly to Basic Beekeeping. I started keeping bees as a hobbyist in 1967, and then went on to get university degrees in biological sciences, specializing in entomology. In 1980 I began to build a migratory beekeeping operation in California, and currently run about 1000 hives with my two sons, from which we make our livings. In 1993, the varroa mite arrived in California, and after it wiped out my operation for the second time in 1999, I decided to "hit the books" and use my scientific background to learn to fight back"

Schoolchildren can learn complex subjects on their own | KurzweilAI - 0 views

  •  
    Educational researchers at the Technical University of Munich (TUM) have found that schoolchildren can independently develop strategies for solving complex mathematical tasks, with weaker students proving just as capable as their stronger classmates. Researchers in mathematics education worked with approximately 1600 8th grade high-school students in various German states. Following an introduction to the general topic by their teachers, the school children were given a workbook of geometric tasks that they had to solve on paper and using a computer over four school periods. Calculating the surface area of Gran Canaria was one of the real-world, free-form assignments the students had to tackle. The workbook material included explanations and examples of various problem-solving approaches. The teachers took a back seat during the session but were on hand to answer questions from the children, who worked in pairs. After testing the students' skills before and after the session, the researchers recorded a significant improvement in their capabilities. The students learned to apply mathematics more effectively, the researchers said. The students were also able to call on these skills in a further test three months later. "We expected students who were weaker at math to benefit more from a greater degree of guidance through the module," said professor Kristina Reiss.  "But we didn't see a significant difference between these and stronger students." The researchers also found that there were also no differences between boys and girls. "We now know that students - also those who are weaker in math - have the skills to master even very complex subject matters at their own pace," said Reiss. Topics: Cognitive Science/Neuroscience

Straight Talk about Vaccination: Scientific American - 0 views

  •  
    Last year 10 children died in California in the worst whooping cough outbreak to sweep the state since 1947. In the first six months of 2011, the Centers for Disease Control and Prevention recorded 10 measles outbreaks-the largest of which (21 cases) occurred in a Minnesota county, where many children were unvaccinated because of parental concerns about the safety of the standard MMR vaccine against measles, mumps and rubella. At least seven infants in the county who were too young to receive the MMR vaccine were infected.

Farthest Galaxy Cluster Ever Detected | Wired.com - 0 views

  •  
    Captured by NASA's Chandra X-ray Observatory and combined with data from infrared and optical telescopes, this image shows the farthest galaxy cluster ever detected. Designated JKCS041, the cluster is located 10.2 billion light-years from Earth, beating the previous distance record by a billion light-years. Astronomers think JKCS041 formed just about as early as was feasible.
