And though we may be away from those holographic representations, the Sloan Digital Sky Survey will soon be entering its third phase, in an attempt to create the biggest 3D map of the universe created so far.

I'm a historian of biology with interests in evolutionary theory, genetics, behavior and the environment. My work explores the varied interpretations and applications of evolutionary theory from the late19th century to the present. My dissertation, "Vero

But the tab as an information technology metaphor is everywhere in use. And whether our tabs are cardboard extensions or digital projections, they all date to an invention little more than a hundred years old. The original tab signaled an information storage revolution and helped enable everything from management consulting to electronic data processing.

For a period of about a decade, extending from my late undergraduate years to my early postdoctoral years, it would be fair to say that I was obsessed with Ockham's razor. I was convinced that it was the key to understanding how we acquire knowledge about the world. I no longer believe in Ockham's razor.

Galison's first question is "What is Context?" He observes that the escape from externalist-internalist debates has resulted in an appeal to context. But, to phrase it in a Seinfeldian way: what's the deal with context?

Japanese researchers said Wednesday they had used stem cells to restore partial mobility in a small monkey that had been paralysed from the neck down by a spinal injury.

Researchers from Rice University and Baylor College of Medicine (BCM) have broken one of the major roadblocks on the path to growing transplantable tissue in the lab: They've found a way to grow the blood vessels and capillaries needed to keep tissues alive.

It's hard not to get lost in a data projection like the NYT's Mapping America: Every City, Every Block, which allows you to parse through 20 or so different projections of the American Community Survey data over the last five years from the Census Bureau.  When you can see the geographic correlations of education levels and income (check out the dividing line at 16th street in both cases), it's a stark reminder of the different Washingtons that exist. Be sure also to check out DCist's initial take (focused on demography and increase/decrease) and GGW's initial take (focused on population shift between wards) This is a data goldmine, and the sort of thing that yours truly is absolutely in love with. Parse through this with us over the next couple weeks.

On July 29th, returning from a trip to Europe, Jacob Appelbaum, a lanky, unassuming 27-year-old wearing a black T-shirt with the slogan "Be the trouble you want to see in the world," was detained at customs by a posse of federal agents. In an interrogation room at Newark Liberty airport, he was grilled about his role in Wikileaks, the whistle-blower group that has exposed the government's most closely guarded intelligence reports about the war in Afghanistan. The agents photocopied his receipts, seized three of his cellphones - he owns more than a dozen - and confiscated his computer. They informed him that he was under government surveillance. They questioned him about the trove of 91,000 classified military documents that Wikileaks had released the week before, a leak that Vietnam-era activist Daniel Ellsberg called "the largest unauthorized disclosure since the Pentagon Papers." They demanded to know where Julian Assange, the founder of Wikileaks, was hiding. They pressed him on his opinions about the wars in Afghanistan and Iraq. Appelbaum refused to answer. Finally, after three hours, he was released. Sex, Drugs, and the Biggest Cybercrime of All Time Appelbaum is the only known American member of Wikileaks and the leading evangelist for the software program that helped make the leak possible. In a sense, he's a bizarro version of Mark Zuckerberg: If Facebook's ambition is to "make the world more open and connected," Appelbaum has dedicated his life to fighting for anonymity and privacy. An anarchist street kid raised by a heroin- addict father, he dropped out of high school, taught himself the intricacies of code and developed a healthy paranoia along the way. "I don't want to live in a world where everyone is watched all the time," he says. "I want to be left alone as much as possible. I don't want a data trail to tell a story that isn't true." We have transferred our most intimate and personal information - our bank accounts, e-mails, photographs, ph

Motion controllers used in gaming systems like the Nintendo Wii revolutionised how video games are played. But now a similar device that's more precise - and even works when an object is in its way - will let you try something more futuristic: making movies in virtual environments. Matt Bett and his team from Abertay University in the UK developed the new motion controller that uses electromagnetic sensors to track its 3D position. The location is then mapped in real time to a virtual video camera on a screen (see video above). By moving the controller around, the camera moves around the scene like a real camera on a rig or it can be fixed to a virtual tripod.

Because the nanotubes have a large surface area , great amounts of energy could be stored in the aerogel, increasing the capacity of lithium batteries or supercapacitors used to store energy generated from renewable resources such as wind and the sun.

The durable and relatively easy-to-produce material has innumerable applications, including recycling waste heat from industrial refineries or using auto exhaust heat to help recharge the battery in an electric car.

RepRap is a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap can print those parts, RepRap is a self-replicating machine - one that anyone can build given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend...RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. We are using 3D printing to do this, but if you have other technologies that can copy themselves and that can be made freely available to all, then this is the place for you too.Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. Our community portal and New Development pages have more information on how to get involved. Use the links below and on the left to explore the site contents.

ScienceDaily (May 19, 2011) - Scientists from the University of Sheffield have developed pigment-free, intensely coloured polymer materials, which could provide new, anti-counterfeit devices on passports or banknotes due to their difficulty to copy.

Greenhouse gas emissions increased by a record amount last year, to the highest carbon output in history, putting hopes of holding global warming to safe levels all but out of reach, according to unpublished estimates from the International Energy Agency.
