Scientific Data Visualization
Scientific data is an essential component of research. It is the "gold" of every researcher, however, it won't shine itself. In order to gain insight into the data, people have to analyze it using different techniques including visualization, which provides a very intuitive and effective way to understand data no matter the data is simple or complex.
Stunning interactive map traces the course of the wind | Digg Technology
Wind direction: it's not the most exciting subject we can think of, but visualization designers Fernanda Viégas and Martin Wattenberg have crafted something truly awe-inspiring from it. Wind Map pulls in hourly data from the National Digital Forecast Database , tracing wind speed and direction in near real-time while providing nationwide maximum and average figures. The result is something remarkably similar to NASA's Perpetual Ocean video, only Wind Map is an interactive, zoomable, and constantly changing project. The designers say they would like to expand the map to cover the entire globe, and want your help to track down global statistics. Viégas and Wattenberg are well known in the field — they created IBM's " Many Eyes " platform before joining Google to lead its "Big Picture" visualization research group.
An invisible, ancient source of energy surrounds us—energy that powered the first explorations of the world, and that may be a key to the future. This map shows you the delicate tracery of wind flowing over the US. The wind map is a personal art project, not associated with any company. We've done our best to make this as accurate as possible, but can't make any guarantees about the correctness of the data or our software.

Before the telescope was invented in 1608, our picture of the universe consisted of six planets, our moon, the sun and any stars we could see in the Milky Way galaxy. But as our light-gathering capabilities have grown, so too have the boundaries of the visible universe. Our interactive map shows how the known universe has grown from 1950 to 2011. In the late 1700s, William Herschel, an English astronomer using a telescope with an 18.7-inch aperture, made the first systematic surveys of the skies, revealing more than 2,000 distant galaxies, nebulae and other objects invisible to the naked eye. Since then, increasingly powerful optical and radio telescopes have greatly expanded our store of knowledge.
The Visible Universe, Then and Now
Hilary Mason, chief scientist at bitly, examined links to 600 science pages and the pages that those people visited next : The results revealed which subjects were strongly and weakly associated. Chemistry was linked to almost no other science. Biology was linked to almost all of them.
What topics science lovers link to the most
Bestiario , the group behind 6pli and a number of other network projects , released their most recent project - Canvi & Temps - that explores the complexity of science since the early 1920s. The first part, Temps , is two linked charts stacked on top of each other. On top are individual articles and on bottom are tags that provide context to those articles. You'll probably be tempted to read the visualization as a stacked area chart, but that wouldn't quite work.
Canvi & Temps: An Exploration of Science Over Time
Canvi & temps are two network browsing spaces built from a compilation of articles, pages, persons and links, all related with complexity in science. The research was carried out by Pau Alsina, Josep Perelló, Michele Catanzaro, Pere Monràs, Carles Tardío, Oriol Vallès, Irma Vilà and Santiago Ortiz. The project is in display at Arts Santa Mónica , in the context of a Cultures of Change exhibit. This historical (it includes citations since 1927) and transversal (it contains more than 30 categories of fields of knowledge) research offers and ample vision of the collection of aproaches, strategies and tactics, reseach methods and interests known as complexity science. Canvi & Temps offer two different ways of experiencing the contents of the network and its interrelations.

Scientists have created the world's first video animation of the female orgasm, using a series of brain scan images. To capture the brain activity, researchers monitored a woman's brain as she lay in a functional magnetic resonance imaging (fMRI) scanner and stimulated herself. Psychologists at Rutgers University in New Jersey , where the study was conducted, hope the research will help them to understand the reasons why some men and women cannot reach sexual climax. Researcher, Professor Barry Komisaruk, who presented the findings at the Society for Neuroscience annual meeting in Washington DC on Monday, told the Guardian :

Cartographies des connaissances scientifiques
Comment cartographier les sciences? De la "Métaphysique" d'Aristote à la classification de Dewey, le classement des savoirs est un enjeu philosophique majeur. Raphaël Velt retrace les cartes historiques et s'intéresse à leurs utilisations.
Nouvelle éruption du Mont Saint Helens... en 3D
Des volcanologues ont créé la toute première simulation en 3D de l’éruption cataclysmique du Mont Saint Helens aux Etats-Unis, qui avait tué 57 personnes il y a 31 ans. Ce système pourrait sauver des vies à l’avenir en aidant les chercheurs à anticiper les scénarios d'éruptions soudaines de volcans endormis. "Pour améliorer nos connaissances sur le fonctionnement des volcans, il est indispensable de visualiser les éruptions en trois dimensions" , a expliqué la volcanologue Amanda Clarke de l’Arizona State University, qui a co-dirigé cette nouvelle étude sur le Mont Saint Helens. Ce volcan de l’Etat de Washington avait commencé à trembler deux mois avant son éruption historique. Ainsi, le 18 mai 1980, un séisme de magnitude 5,1 réveille le Mont Saint Helens.dataviz
