Submission + - KDE Plasma Can Now Run On Wayland (phoronix.com)

An anonymous reader writes: With the upcoming KDE 4.11, there's an initial Wayland backend through the KWin manager. The developer behind the code notes on his blog: "Once the system is fully started you can just use it. If everything works fine, you should not even notice any difference, though there are still limitations, like only the three mouse buttons of my touchpad are supported ;-)"

Submission + - Bessel beam "tractor beam" concept theoretically demonstrated (gizmag.com)

cylonlover writes: Last year, NASA revealed it was evaluating three potential “tractor beam” technologies to deliver planetary or atmospheric particles to a robotic rover or orbiting spacecraft. At the time, the third of these, which involved the use of a Bessel beam, only existed on paper. Researchers at Singapore’s Agency for Science, Technology and Research (A*STAR) have now proven the theory behind the concept, demonstrating how a tractor beam can be realized in the real world – albeit on a very small scale.

Submission + - Venus to Appear in Once-In-A-Lifetime Event (sciencedaily.com)

revealingheart writes: ScienceDaily reports that on 5 and 6 June this year, millions of people around the world will be able to see Venus pass across the face of the Sun in what will be a once-in-a-lifetime experience. It will take Venus about six hours to complete its transit, appearing as a small black dot on the Sun's surface, in an event that will not happen again until 2117.

Transits of Venus occur only on the very rare occasions when Venus and Earth are in a line with the Sun. At other times Venus passes below or above the Sun because the two orbits are at a slight angle to each other. Transits occur in pairs separated by eight years, with the gap between pairs of transits alternating between 105.5 and 121.5 years — the last transit was in 2004.

"We are fortunate in that we are truly living in a golden period of planetary transits and it is one of which I hope astronomers can take full advantage," writes Jay M Pasachoff, an astronomer at Williams College, Massachusetts.
