writes: You paid for it, you should be able to read the results of publicly funded research. The National Institutes of Health have had a very successful open access mandate requiring that the results of federally funded biomedical research be published in open access journals. Now there is a White House petition to broaden this mandate. This is a jobs issue. Startups and midsize business need access to federally funded technology research. It is a health care issue, patients and community health providers need access, not a few scientists in well funded research institutes, and even wealthy institutions like Harvard are finding the prices of proprietary journals unsustainable.Link to Original Source
writes: The Register has a piece today about overcoming one of the biggest challenges to migrating to cloud-based storage: how to get all that data onto the service provider's disks. With all of the enterprisey interweb solutions available, the oldest answer is still the right one: ship them your disks.

writes: The new “six strikes” anti-piracy policy soon to be implemented by a number of major Internet service providers in the United States will reportedly stumble out of the gate. The policy, which is set to be adopted by Comcast, Cablevision, Verizon, Time Warner Cable and other ISPs, will see action taken against users caught downloading pirated files in six steps, ultimately resulting in bandwidth throttling or even service suspensions. The system responsible for managing the new policy may not be ready on schedule, however, and the targeted launch date of July 12th may slip back as a result...Link to Original Source

But the mechanisms behind this psychological phenomenon have remained unclear. A study now suggests that simply taking a break does not bring on inspiration — rather, creativity is fostered by tasks that allow the mind to wander.
The researchers gave 145 students 2 minutes to list as many possible uses for an everyday object (the creative thinking task).
Participants then either rested, undertook a demanding memory activity that required their full attention or engaged in an undemanding reaction-time activity known to elicit mind-wandering. A fourth group of students had no break. The researchers then set the students a second set of unusual-uses tasks and found those that had, in the interim, been set the undemanding task that encouraged mind-wandering performed an average of around 40% better than they did before. The students in the other three groups showed no improvement.Link to Original Source
writes: During the latter half of the twentieth century, global sea level rose by about 1.8 millimetres per year. The combined contribution from heating of the oceans, which makes the water expand, along with melting of ice caps and glaciers, is estimated to be 1.1 millimetres per year, which left some 0.7 millimetres per year unaccounted for.
It seems that the effects of human water use on land could fill that gap. Researchers report in Nature Geoscience that land-based water storage could account for 0.77 millimetres per year, or 42%, of the observed sea-level rise between 1961 and 2003. The extraction of groundwater for irrigation and home and industrial use, with subsequent run-off to rivers and eventually to the oceans, represents the bulk of the contribution.
It would be even worse if we weren't also locking up lots of water from rivers behind dams like the Hoover Dam.Link to Original Source
