Ants invented the internet?


Ask who invented the Internet and you’ll spark off an argument with everyone championed from Tim Berners Lee to Nikola Tesla. However, two Stanford scientists claim that the inventor may have had six legs, antennae and a taste for disrupting picnics. Professor of biology Deborah Gordon and professor of computer science Balaji Prabhakar say that red harvester ants (Pogonomyrmex barbatus) use the same Transmission Control Protocol (TCP) in foraging that the internet uses to manage data transmissions – making a sort of “Anternet.”..

Curiosity rolls out, and writes a message on Mars


The NASA Mars rover Curiosity began its mission of exploration this week and as it rolled out, it wrote the place of its birth on the Martian surface. The 4x4-sized unmanned explorer will travel a quarter of a mile (400 m) to an area where it will test its robotic arm and may use its sample-collecting drill for the first time. As it goes along, the treads on Curiosity’s six wheels spell out “JPL” (Jet Propulsion Laboratory) over and over in Morse code... Continue Reading Curiosity rolls out, and writes a message on Mars

Astronauts go potholing to train for space


In Robert Heinlein’s 1948 novel Space Cadet, spacemen of the future learned their profession aboard an orbital training ship. Because there aren’t any retired space ships in orbit to play the part of PRS James Randolph in real life, astronauts headed for duty aboard the International Space Station must find earthbound substitutes. For the European Space Agency (ESA), the alternative is to turn smartly about and go underground. On September 7, CAVES 2012 (Cooperative Adventure for Valuing and Exercising human behavior and performance Skills) will see six international astronauts descend into the caverns of the island of Sardinia to learn how to use space procedures by going potholing...

Makerplane aims to create the first open source aircraft


The idea of owning your own plane is the stuff of daydreams. It’s incredibly appealing, but despite some (relative)drops in pricing in recent years, it remains incredibly expensive. If you build your own plane from a kit, it’s a bit cheaper than buying one, but the odds are that you’ll never complete the job because kitplanes are notoriously difficult to build. However, that may be changing. MakerPlane is a project that aims to create an open source aircraft designed by contributors and built with digital manufacturing processes. You can’t download the plans into your 3D printer and fly away that afternoon, but it does hold the promise of making amateur aviation a lot more accessible...

One-molecule thick material promises electronics revolution


Imagine a world where rooms are lit by their walls, clothes are smartphones and windows turn into video screens. That may seem like a bit of science fiction, but not for long. Researchers at MIT are using a two-dimensional version of molybdenum disulfide (MoS2) to build electrical circuits that may soon revolutionize consumer electronics...

New nanocrystals let solar panels generate electricity ... and hydrogen gas


At first glance, photovoltaic solar panels are brilliant. They’re self-contained, need no fuel and so long as the sun is shining, they make lots of lovely electricity. The trouble is, they’re expensive to make, batteries are poor storage systems for cloudy days, and the panels have a very short service life. Now, Dr. Mikhail Zamkov of Ohio's Bowling Green State University and his team have used synthetic nanocrystals to make solar panels more durable as well as capable of producing hydrogen gas. ..

LiftPort plans to build space elevator on the Moon by 2020


When the late Neil Armstrong and the crew of Apollo 11 went to the Moon, they did so sitting atop a rocket the size of a skyscraper that blasted out jets of smoke and flame as it hurtled skyward. For over half a century, that is how all astronauts have gone into space. It’s all very dramatic, but it’s also expensive. Wouldn’t it be cheaper and easier to take the elevator? That’s the question that Michael Laine, CEO of LiftPort in Seattle, Washington, hopes to answer with the development of a transportation system that swaps space-rockets for space-ribbons...

Curiosity's ChemCam passes first tests with flying colors


NASA’s Mars rover Curiosity has already fired its laser over 500 times as it studies its surroundings as engineers at the Jet Propulsion Laboratory (JPL) calibrate its sensors. In a classic example of “waste not, want not” Curiosity concentrated its activity on a patch of rocks that were uncovered by the rocket backwash of thesky crane that delivered the unmanned explorer to the Martian surface on August 6...

Glycerol additive makes cruise ships greener

The bunker fuel used in cruise liners and freighters is some of the cheapest, crudest fuel available. It’s also among the dirtiest. Scientists from the Maine Maritime Academy and SeaChange Group LLC led by George N. Harakas, Ph.D announced at the 244th National Meeting & Exposition of the American Chemical Society that they have developed what they call "Bunker Green" fuel. This fuel uses an ingredient commonly used in food and medicine to reduce sulfur and other emissions in ocean vessels... Continue Reading Glycerol additive makes cruise ships greener

Edible dispersant could provide more eco-friendly way to fight oil spills


Some people believe that there’s no problem that peanut butter, chocolate and whipped cream can’t solve. These people could be onto something with news that a team of researchers has developed a new, safer oil dispersant that uses edible ingredients found in the aforementioned trio of treats. The new dispersant could save the lives of thousands of birds and animals caught in environmental catastrophes. Read More

Mars Express takes close up of Phobos


NASA’s Curiosity rover may be stealing the headlines, but there is other news coming from Mars. Recently, the European Space Agency’s (ESA) Mars Express probe made a 100-kilometer (62-mile) flyby of the Martian moon Phobos and returned a high-resolution 3D image filled with remarkable detail. The image includes a profile of Stickney crater, which dominates the right-hand side, and the grooves associated with the impact of the asteroid that created it thousands of years ago. Read More

Oak Ridge develops improved way of extracting uranium from seawater


The world’s estimated reserves of uranium are only 5.5 million tonnes (6 million tons) and with the growing demand for reliable energy free of greenhouse emissions leading to more and more nuclear plants being built, that supply may not last very long. Some estimates place the time before all the uranium is gone at between 50 and 200 years. However, the oceans of the world contain 4.1 billion tonnes (4.5 billion tons) of uranium dissolved in seawater. That’s enough to last something on the order of 6,500 years. The tricky bit is getting it out, but a team at Oak Ridge National Laboratory, Tennessee has come a step closer to economically extracting uranium from seawater with a new material that is much more efficient than previous methods...

Curiosity goes for a test drive


The Curiosity rover has taken its first drive today on Mars. It wasn’t much of a road trip. The unmanned craft went about 15 feet (4.57 m), turned 120 degrees and then reversed about 8 feet (2.43 m). Curiosity is now about 20 feet (6.09 m) from its landing site, now named Bradbury Landing after the late author Ray Bradbury. That may not seem like much, but it was a successful test of Curiosity’s mobility and takes it a step (or a roll) closer to beginning its two-year mission to look for areas where life may have or does exist on the Red Planet...

Scientists develop material that's harder than diamonds


Diamonds may be forever, but they aren’t what they were. True, they shine just as brightly and they’re as hard as ever, but scientists from the Carnegie Institution of Washington are giving them some competition. An international team led by Carnegie’s Lin Wang have discovered a new substance that is not quite crystalline and not quite non-crystalline, yet is hard enough to dent diamonds. ..

DARPA developing unmanned sub hunters


Submarine combat may seem like an obsolete relic from World War II films and Cold War thrillers, but the past 20 years have seen a growing number of increasingly quiet diesel-electric submarines turning up in some very unfriendly navies. In order to counter this threat, the Defense Advanced Research Projects Agency (DARPA) has awarded a contract to the Science Applications International Corporation (SAIC) of McLean, Virginia to develop unmanned submarine hunters capable of operating for months on end without human intervention...

Next Mars mission – after Curiosity comes InSight


Feeling very confident after the perfect landing of the Curiosity rover on Mars on August 6th, NASA has announced its next mission to the Red Planet. In 2016, the US space agency will launch the unmanned InSight lander to Mars. Unlike Curiosity, InSight will be a static lander loaded with instruments designed to study the deep geology of Mars and answer such questions as whether the core of the planet is liquid or solid, and why Mars hasn’t any shifting tectonic plates like Earth.
