Glow kitties cat Just in time for Halloween, a team of scientists has introduced a new breed of kittens that glow in the dark. They’re cute, cuddly and bright, with fur that shines yellow-green when you turn off the light. But like the bag you carry around for trick-or-treating, it’s what’s inside these cats that counts. The disease is called Feline Immunodeficiency Virus, or FIV. Because HIV and FIV are similar, scientists suspect that if they find a way to fight FIV, they might discover a way to help people with HIV. Eric Poeschla led the study on glowing kittens. A virus (like FIV or HIV) is a tiny particle that finds and attacks cells in the body. Poeschla and his colleagues know that FIV can be stopped — but so far, only in rhesus monkeys. A cell’s genes contain the recipes for all the proteins it needs. Poeschla’s team then implanted the gene-modified eggs in a cat; the cat later gave birth to three kittens.

10 Websites To Make You Think | The Online Learning Blog from Study2U Supposedly browsing the internet requires more brain power than watching television. Although judging from some of the websites we’ve come across that assumption is cast into doubt. Here’s some of the sites we like that might get your brain to sit up and listen. Ted A conference that started in 1984 bringing together experts in technology, entertainment and design quickly grew into so much more. The conference itself is invitation only, but the website features all the talks at the conference in high res video format. New Scientist The New Scientist website carries new articles from the magazine as well as the NS archive of over 76,000 pieces.

Stop fetishizing the scientific paper: Our invited Comment in Nature courtesy Nature If there’s one consistent lesson of covering retractions, it’s that science doesn’t stop when researchers publish a paper. But what also seems true is that once a paper is published, lots of people — authors and editors, in particular — are often reluctant to say just what’s happened next, particularly if it casts the study or the journal in a negative light. Some of this is understandable, given the weight given papers by tenure committees and granting agencies. What is needed, instead, is a system of publication that is more meritocratic in its evaluation of performance and productivity in the sciences. As it happens, there will soon be a way to do all of that: CrossMark, about to be launched by CrossRef. The idea is for every piece of content to include a clickable logo that will let a reader know whether there have been any corrections, retractions or other revisions. Like this: Like Loading...

ConvertAll – L’utilitaire ultime pour convertir des unités de mesure ConvertAll – L’utilitaire ultime pour convertir des unités de mesure En général, quand je dois convertir des valeurs, j'utilise Google. Soit ce dernier me fait la conversion directement, soit je trouve toujours un site obscur capable de me convertir des chiffres dans une autre unité de mesure. Je ne pense pas que ça intéressera, monsieur et madame, tout le monde, mais pour ceux qui bossent quotidiennement avec des unités de mesure de toutes sortes, ça peut rendre de gros services. ConvertAll est téléchargeable ici. [Source et photo] Vous avez aimé cet article ? Unseen Titanic The wreck sleeps in darkness, a puzzlement of corroded steel strewn across a thousand acres of the North Atlantic seabed. Fungi feed on it. Weird colorless life-forms, unfazed by the crushing pressure, prowl its jagged ramparts. From time to time, beginning with the discovery of the wreck in 1985 by Explorer-in-Residence Robert Ballard and Jean-Louis Michel, a robot or a manned submersible has swept over Titanic’s gloomy facets, pinged a sonar beam in its direction, taken some images—and left. In recent years explorers like James Cameron and Paul-Henry Nargeolet have brought back increasingly vivid pictures of the wreck. Until now. On closer inspection, though, the site appears to be littered with man-made detritus—a Jackson Pollock-like scattering of lines and spheres, scraps and shards. Here, in the sweep of a computer mouse, is the entire wreck of the Titanic—every bollard, every davit, every boiler. What is it about the wreck of the R.M.S. Which is exactly what’s happened.

Attractive Italian Viaduct Has Wind Turbines Built In A new bridge concept incorporates wind and solar energy into its design, generating 40 million kilowatt-hours per year — and looking pretty slick to boot. The Solar Wind concept would use the space between an existing viaduct in southern Italy to install 26 wind turbines, which designers Francesco Colarossi, Giovanna Saracino and Luisa Saracino say could provide 36 million kilowatt hours of electricity every year. The design team conceived the Solar Wind project for a contest that aims to repurpose some old, unused viaducts near Calabria, a region in the toe of Italy. It would cost about $55 million to demolish the viaducts, so town officials held a contest for proposals that would re-use them in an environmentally friendly way. The wind turbine bridge took second place. The proposal also includes a solar-paneled roadway to provide another 11.2 million kilowatt hours, Colarossi and colleagues say.
TEDxSF - A Curation Of People And Ideas... Posted by Tom Foremski - June 5, 2011 I've been to several TEDxSF events but the most recent one felt like a breakthrough event because of the mix of people and talks, plus the new venue. The event was sold out with about 650 tickets for the Yerba Buena location, a larger theater than the Academy of Sciences, where it used to be held. The mix of people was eclectic as always. There were at least two or three talks where I wished for the return of the old Vaudeville stage hook, or maybe a remote controlled trapdoor. But it was a packed afternoon, from noon to 6pm, a bit too long. TED talks are a form of modern theater within an old school format in that it's a one-way stage. However, the formulaic format of TED talks is pretty good, so maybe the organizers know not to mess with what works. Among the standout performances: - Dr. - Eythor Bender and his eLEGS exoskeletons, he showed a woman paralyzed from the waist down walking onto the stage. Simon Mainwaring.
