Cryptographers chosen to duke it out in final fight - physics-math - 13 December 2010 A competition to find a replacement for one of the gold-standard computer security algorithms used in almost all secure, online transactions just heated up. The list of possibilities for Secure Hash Algorithm-3, or SHA-3, has been narrowed down to five finalists. They now face the onslaught of an international community of "cryptanalysts" – who will analyse the algorithms for weaknesses – before just one is due to be selected as the winner in 2012. The competition, which is being run by the US National Institute of Standards and Technology in Gaithersburg, Maryland, is a huge deal for cryptographers and cryptanalysts alike.
NASA Creates World's First Global Forest Map Using Lasers Image by Jesse Allen and Robert Simmon Scientists, using three NASA satellites, have created a first-of-its-kind map that details the height of the world's forests. The data was collected from NASA's ICESat, Terra and Aqua satellites. The latter two satellites are responsible for most of NASA's Gulf spill imagery. The data collected will help scientists understand how the world's forests both store and process carbon. While there are many local and regional canopy maps, this is the very first global map using a uniform method for measure.

Religion no excuse for promoting scientific ignorance - science-in-society - 08 February 2011 The US constitution allows people to believe what they want. However, it does not require universities to promote ignorance LAST month, the University of Kentucky in Lexington paid $125,000 to settle a religious discrimination lawsuit brought by astrophysicist Martin Gaskell. Gaskell claimed the university did not appoint him director of their student observatory because of his Christian faith, despite him being the best candidate. The settlement - which is not an admission of wrongdoing - means the suit will not come to court.
Infographic of the Day: It's a Small World, Afterall If you're wondering how "close" two places are, a geographic map doesn't help much anymore. If the airports are good--or if there's a bullet train nearby--hundreds of miles might as well be down the street. Point being, "distance" is now really a function less of geography, than of the transport networks we've invented. Which is why researchers at the European Commission's Joint Research Centre in Ispra, Italy, and the World Bank, created this gorgeous map. They first created a model, which calculated how long it would take to travel from a given point, to the nearest city of 50,000 people or more; the model includes rail, road, and river networks.
Map Collection Digital Maps - Harvard College Library - StumbleUpon The Harvard Map Collection is one of the oldest and largest collections of cartographic materials in the United States with over 500,000 items. Resources range from 16th century globes to modern maps and geographic information systems (GIS) layers. A selection of our materials has been digitally imaged and is offered both as true picture images and georeferenced copies. This Virtual Collection includes those maps and atlases that are available through the Harvard Image Delivery Service.
America as it could have been: 8 North American nations that didn’t make it to the 21st Century North America. We all recognise it on a map: it’s the continent above South America. Most of us can even name the countries, Canada, the United States, Mexico... other Spanish speaking ones... But, the point is, it might not have turned out that way. North America could have been as difficult a continent to learn as Europe if history had been different. Here are eight nations that all existed in North America mat one point in time, but didn't last to the twenty-first century.
World Sunlight Map Watch the sun rise and set all over the world on this real-time, computer-generated illustration of the earth's patterns of sunlight and darkness. The clouds are updated daily with current weather satellite imagery. The Mercator projection used here is one way of looking at the spherical earth as a flat map. Used since the 16th century for navigation, straight lines on this map can be used accurately as compass bearings but the size and shape of continents are distorted.

The Economics of Happiness In the last few years, a growing number of economists have been discovering happiness. It's not that they are spending more time admiring flowers, helping old folks cross the road, dancing on the street or baking pies for neighbors. In fact, these happiness economists are working long hours in soul-numbing ways, torturing data with their latest econometric techniques to force deeply buried facts to the surface. What is different is that these economists are revisiting old assumptions and asking new questions. Jevons' Paradox and the Perils of Efficient Energy Use It's a given among Peak Oilers and New Urbanists alike that the imminent and permanent return of high oil prices will send convulsions through the suburban American landscape. But it's one thing when professional Jeremiahs like James Howard Kunstler preach this to the converted week after week, and something else when the Urban Land Institute and PricewaterhouseCoopers advise commercial real estate investors to "shy away from fringe places in the exurbs and places with long car commutes or where getting a quart of milk takes a 15-minute drive." Oil shocks will do what urban planners can't seem to and the government won't (through sharply higher gas taxes or putting a price on carbon): force people to live at greater densities.
Mapping a World of Human Activity With the world networked on an unprecedented scale, and the global population hitting 7 billion only weeks ago, we are living in a uniquely interconnected era, creating new opportunites and dependencies. It's the result of millenia of exploration, travel, exploitation, and innovation, and the Anthropocene, meaning “the new human-dominated period of the Earth’s history,” is a term coined in 2000 to describe this epoch. A Cartography of the Anthropocene is an effort by global education organization Globaïa to map this epoch, illustrating the various ways that global humanity connects and is interdependent.
