Water filter from the sapwood in pine tree branches If you've run out of drinking water during a lakeside camping trip, there's a simple solution: Break off a branch from the nearest pine tree, peel away the bark, and slowly pour lake water through the stick. The improvised filter should trap any bacteria, producing fresh, uncontaminated water. In fact, an MIT team has discovered that this low-tech filtration system can produce up to four liters of drinking water a day -- enough to quench the thirst of a typical person. In a paper published this week in the journal PLoS ONE, the researchers demonstrate that a small piece of sapwood can filter out more than 99 percent of the bacteria E. coli from water. They say the size of the pores in sapwood -- which contains xylem tissue evolved to transport sap up the length of a tree -- also allows water through while blocking most types of bacteria. "Today's filtration membranes have nanoscale pores that are not something you can manufacture in a garage very easily," Karnik says. Seeing red

The bots of war 45inShare Jump To Close By the time the sun rose on Friday, December 19th, the Homestead Miami race track had been taken over by robots. It was the start of the Robotics Challenge Trials, a competition put on by the Defense Advanced Research Projects Agency (DARPA), the branch of the US Department of Defense dedicated to high risk, high reward technology projects. The eight robots that scored highest in the trials would go on to the finals next year, where they will compete for a $2 million grand prize. Mark Gubrud, a former nanophysicist and frumpy professor sort, fit right in with the geeky crowd. “DARPA’s trying to put a face on it, saying ‘this isn’t about killer robots or killer soldiers, this is about disaster response,’ but everybody knows what the real interest is,” he says. Around a year ago, the Department of Defense released directive 3000.09: "Autonomy in Weapons Systems." "It's a veto power that you have about a half-second to exercise. Autonomous robots by design Humanoid Land
Descopera.ro - E Lumea Ta! Existencialismo Origem: Wikipédia, a enciclopédia livre. Existencialismo é um termo aplicado a uma escola de filósofos dos séculos XIX e XX que, apesar de possuir profundas diferenças em termos de doutrinas,[1] [2] [3] partilhavam a crença que o pensamento filosófico começa com o sujeito humano, não meramente o sujeito pensante, mas as suas ações, sentimentos e a vivência de um ser humano individual.[4] No existencialismo, o ponto de partida do indivíduo é caracterizado pelo que se tem designado por "atitude existencial", ou uma sensação de desorientação e confusão face a um mundo aparentemente sem sentido e absurdo.[5] Muitos existencialistas também viam as filosofias académicas e sistematizadas, no estilo e conteúdo, como sendo muito abstractas e longínquas das experiências humanas concretas.[6] [7] Origens[editar | editar código-fonte] O rótulo foi aplicado retrospectivamente a outros filósofos para os quais a existência e, em particular, a existência humana eram tópicos filosóficos fundamentais.

Les Réplicateurs sont là L'histoire commence avec le projet DM3 (Diamagnetic Micro Manipulation) de la DARPA, l'agence américaine pour la recherche militaire avancée. Le SRI a donc développé une colonie de micro-robots, chacun d'eux ne mesurant que quelques millimètres et qui sont capables de travailler à l'unisson ou en équipe pour assembler des composants et effectuer des tâches complexes. Comment ça marche ? Ces micro-robots sont capables de suivre des trajectoires définies par un champ magnétique préprogrammé et contrôlable via un logiciel sur ordinateur.
We get touchy-feely with Fujitsu's haptic sensory tablet (video) Since Fujitsu's prototype Haptic Sensor Tablet revealed yesterday is all about touch, describing it will be like trying to explain how a steak tastes. But here goes: It works by emitting ultrasonic vibrations below the touchscreen, which can be pulsed with varying force on any region of the screen. Those oscillations actually push your finger off the surface of the tablet and, depending on the strength, can give different tactile sensations. For instance, a high-pressure layer of air can reduce friction, making the surface of the screen seem slippery. At least, that's the theory. Fujitsu Haptic Sensory Tablet hands-on See all photos 6 Photos Comments Parker - Release Date January 25, 2013 Another box office bomb from hack director Taylor Hackford and failing fledgling movie studio FilmDistrict, (which will ultimately shutter by end of 2014, if not sooner). A thief with a unique code of professional ethics is double-crossed by his crew and left for dead. Assuming a new disguise and forming an unlikely alliance with a woman on the inside, he looks to hijack the score of the crew's latest heist. Director Taylor Hackford has had a bouncy 40 year career as a director. While he has directed movies constantly during the past four decades, less than a handful of his films have been bonafide hits. Among them An Officer And A Gentleman from 1982, Dolores Claiborne from 1995 and Ray from 2004. Taylor Hackford is actually most famous for being married to Oscar winner (The Queen) Helen Mirren.

Future Day Die Hard 5 release date, movie poster, trailer, cast The fifth in the 25 year old big screen franchise starring Bruce Willis. Take-no-shit, Yipee-Ki-Yay-Mother-fucker cop John McClane for the first time finds himself on foreign soil after traveling to Moscow to help his wayward son Jack -- unaware that Jack is really a highly-trained CIA operative out to stop a nuclear weapons heist. With the Russian underworld in pursuit, and battling a countdown to war, the two McClanes discover their opposing methods make them unstoppable heroes. For once in recent memory a movie studio has made a smart decision; that releasing Die Hard 5, (as they had the previous film in the franchise, Die Hard 4), with a PG-13 rating, would amount to sacrilege to all who are wild about movies. We are 100% confident that they are 100% justified in their thinking. Had the fourth Die Hard movie been released with an R-ratings as the first three Die Hard movies were, it would have made a LOT more money at the movie box office.
Lectures » How To Boldly Go Into Space: An Insider’s Look into How Space Missions are Created, Funded, Built, Launched, and Run DRAWING ON THEIR DECADES OF WORK FOR NASA and the Jet Propulsion Laboratory (JPL) Drs. Linda and Thomas Spilker give us an inside view of what goes into the unmanned space program, from the origin of a space mission, to how the funds are found to finance it, to how the spacecraft is designed and built, and to the launching and running of such a mission, often designed to last for years and even decades. How do you get a spacecraft to Saturn, anyway? Dr. Dr. The views expressed by the speaker are solely those of the speaker.
