Nanoelectronics could get a boost from carbon research

more »
Scientists have investigated a way to create linear chains of carbon atoms from laser-melted graphite. The material, called carbyne, could have a number of novel properties, including the ability to adjust the amount of electrical current traveling through a circuit, depending on the user's needs.

“WikiGate” raises questions about Wikipedia’s commitment to open access

Science Focus

original post »

Scientific publisher Elsevier has donated 45 free ScienceDirect accounts to "top Wikipedia editors" to aid them in their work. Michael Eisen, one of the founders of the open access movement, which seeks to make research publications freely available online, tweeted that he was "shocked to see @wikipedia working hand-in-hand with Elsevier to populate encylopedia w/links people cannot access," and dubbed it "WikiGate." Over the last few days, a row has broken out between Eisen and other academics over whether a free and open service such as Wikipedia should be partnering with a closed, non-free company such as Elsevier.

Eisen's fear is that the free accounts to ScienceDirect will encourage Wikipedia editors to add references to articles that are behind Elsevier's paywall. When members of the public seek to follow such links, they will be unable to see the article in question unless they have a suitable subscription to Elsevier's journals, or they make a one-time payment, usually tens of pounds for limited access.

Eisen went on to tweet: "@Wikipedia is providing free advertising for Elsevier and getting nothing in return," and that, rather than making it easy to access materials behind paywalls, "it SHOULD be difficult for @wikipedia editors to use #paywalled sources as, in long run, it will encourage openness." He called on Wikipedia's co-founder, Jimmy Wales, to "reconsider accommodating Elsevier's cynical use of @Wikipedia to advertise paywalled journals." His own suggestion was that Wikipedia should provide citations, but not active links to paywalled articles.

Celestial Bauble, Nebula N90 and Pulsar SXP1062 Wrapping Paper

Get your out-of-this-world gift wrap here! Perfect for Christmas gifts for anyone who is fascinated by what the universe holds in store for us!


tagged with: sculptured gas clouds, hot young stars, star galaxies, outer space picture, supernova remnant, star factory, small magellanic cloud, smc, celestial bauble, hrbstslr sxp1062, star incubator

Galaxies, Stars and Nebulae series: In this composite image, X-rays from Chandra and XMM-Newton have been colored blue and optical data from the Cerro Tololo Inter-American Observatory in Chile are colored red and green. The flowering shape is a star factory and the bright blue star is the pulsar, known as SXP 1062. Astronomers are interested in SXP 1062 because it's spinning unusually slowly - about once every 18 minutes. (In contrast, some pulsars are found to revolve up to 1000 times per second)

Carina Nebula, Star Forming Gas-cloud Sculpture Star Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: billowing interstellar gas clouds, cnbigc, star forming activity, carina nebula, amazing space sculpture, star nurseries, stellar winds, young hot stars, gas cloud sculpture

Galaxies, Stars and Nebulae series A beautiful space photograph featuring the 7500 light year distant Carina Nebula. This Hubble image shows rich, interstellar gas clouds feeding the formation of new stars. As a proto star forms, the gas clouds get dragged to its surface and some gets emitted as tight jets of material travelling at hundreds of miles per second. These in turn help sculpt the gas clouds into weird and grotesque shapes, some looking like strange worms, swimming through space.

Pickering's Triangle in the Veil

more »
Chaotic in appearance, these filaments of shocked, glowing gas break across planet Earth's sky toward the constellation of Cygnus, as part of the Veil Nebula. The Veil Nebula itself is a large supernova remnant, an expanding cloud born of the death explosion of a massive star. Light from the original supernova explosion likely reached Earth over 5,000 years ago. Blasted out in the cataclysmic event, the interstellar shock waves plow through space sweeping up and exciting interstellar material. The glowing filaments are really more like long ripples in a sheet seen almost edge on, remarkably well separated into the glow of ionized hydrogen and sulfur atoms shown in red and green, and oxygen in blue hues. Also known as the Cygnus Loop, the Veil Nebula now spans nearly 3 degrees or about 6 times the diameter of the full Moon. While that translates to over 70 light-years at its estimated distance of 1,500 light-years, this field of view spans less than one third that distance. Identified as Pickering's Triangle for a director of Harvard College Observatory and cataloged as NGC 6979, the complex of filaments might be more appropriately known as Williamina Fleming's Triangular Wisp.

Tarantula Nebula Star Forming Gas Cloud Sculpture Star Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: envelope sealers, tnlmcsfr, billowing interstellar gas clouds, awesome hubble images, tarantula nebula, large magellanic cloud, star forming activity, young hot stars, star nurseries, triggering star formation

Galaxies, Stars and Nebulae series An awesome mobile phone shell featuring the Tarantula Nebula of the Large Magellanic Cloud, which is the nearest galaxy to the Milky Way, our galactic home. This Hubble image shows old stars from the distant past and rich, interstellar gas clouds feeding the formation of new ones. The most massive and hottest stars are intense, high-energy radiation sources and this pushes away what remains of the gas and dust, compressing and sculpting it. As the whorls and eddies clump and stretch it, gravity takes over and the birth of the next generation of new stars is triggered.
