NASA & ESA test "interplanetary Internet" connection, controlled a Lego robot in Germany from the ISS
NASA and the European Space Agency have just gone where no man has ever gone before, by testing out an "interplanetary Internet" connection. It wasn't quite Mars to Earth, but involved an astronaut on the International Space Station controlling a small robot here on Earth.
NASA is trying to respark the imagination of Americans, and with this latest mission showing off a new communications protocol, it is definitely on the right path. A new communications protocol capable of transmitting data between planets and spaceships - just typing this feels odd, but quite exciting at the same time.
The new protocol is known as Disruption Tolerant Networking (DTN), and is capable of allowing for many disconnections and errors that would occur when a signal travels long distances through space. NASA deputy associate administrator for space communications and navigation, Badri Younes, said in a statement:
The demonstration showed the feasibility of using a new communications infrastructure to send commands to a surface robot from an orbiting spacecraft and receive images and data back from the robot. The experimental DTN we've tested from the space station may one day be used by humans on a spacecraft in orbit around Mars to operate robots on the surface, or from Earth using orbiting satellites as relay stations.
It looks like China is taking off to the stars next year, with a new manned space mission locked in for June 2013. A senior official in charge of the manned space programme has said that the three-person crew would consist of two men and one woman, reports the BBC.
China is the third country to independently send a person into space, second only after Russia and the United States. The new plan follows the flight of the Shenzhou 9 spacecraft, which returned to Earth in late-June. The Shenzhou 9 was part of China's first manual space docking mission, which was a huge milestone in China's ambitious space programme.
The mission also saw another milestone: carrying China's first female astronaut, Liu Yang. Next year's mission could happen as early as June, but there are back-up launch windows slotted in for both July and August, according to Niu Hongguang, deputy commander-in-chief of the manned space programme.
Solar panels are slowing oozing their way across the world, being slapped onto peoples' houses to power their houses. But, some panels don't have enough tech inside to completely power your house from the sunlight captured.
Well, research and development into new methods of capturing sunlight on solar panels is an ongoing thing, with the New Zealand territory of Tokelau being a great example. Tokelau is a group of three islands in the South Pacific which now has enough solar panel installations to completely meet their electrical needs.
Just recently, the islands relied on importing diesel fuel to power electrical generators, but as the New Zealand Foreign Affairs Minister, Murry McCully has said, this has huge economic and environmental costs. The project was funded by the New Zealand government to the tune of $7 million, with a collection of solar panels installed on each of the three islands.
Physicists could prove that we live in a computer simulation, probably without sunglasses, leather and slow-mo
When The Matrix came out in 1999, so many people walked out thinking "are we living in a computer program?" and it looks like physicists are thinking outside the square when it comes to our origins.
Nick Bostrom has hypothesized that the existence of our race could end up being nothing more than the algorithmic results of a computer simulation. It may sound a little nuts, but it sounds no less crazy than some theories given to use by not science and religion.
The best bit of this is that researchers have reached the point where they have a way that they can test this thought experiment. A team of scientists out of the University of Bonn in Germany suggest that even the most powerful Universe simulation would be subject to certain limitations of its host Universe.
Felix Baumgartner has become the first skydiver to reach a truly special milestone: skydiving from the edge of our planet toward the ground faster than the speed of sound. Baumgartner reached a top speed of 833.9mph (1342km/h).
Baumgartner, an Austrian skydiver, spent two hours travelling up in a balloon to reach dizzying heights of 128,100 feet, (24 miles or 39km). After which he jumped out of his capsule, and spend four minutes in complete freefall, all in a pressurized spacesuit. This gave Baumgartner a world record for the highest ever freefall.
Once he hit the ground, he took a few steps and dropped to his knees, raising his hands in absolute triumph. Baumgartner said to the media just after his record-breaking skydive:
Let me tell you - when I was standing there on top of the world, you become so humble. You don't think about breaking records anymore, you don't think about gaining scientific data - the only thing that you want is to come back alive.
New laser is being constructed, would be powerful enough to tear apart the vacuum of space-time itself
Well, this is interesting - the European Commission has approved the construction of three new huge research lasers, leaving the door open on a fourth that would, for a tiny instant, be several hundred times more powerful than the entirety of the power generated by the human race.
Yes, that is very, very powerful. The scientists hope to actually create virtual particules from absolutely nothing. The fourth laser when at peak power in Europe's Extreme Light Infrastructure project (ELI) would combine a total of ten beams into a single pulse at 200 petawatts. The entire Earth doesn't even generate that much power at any one moment, and if we're talking scale, it is more total power than the Earth receives from our star, the sun.
This is not the type of laser that stays on continuously, and will only use this mammoth amount of power for just 1.5 x 10^-14 second .This is the same time that "it takes for light to travel from one side of a human hair to the other, if you shave your hair down by 90%", reports Dvice.
Scientists manage to produce gold from a toxic gas by using bacteria, won't help our financial problems
Michigan State University scientists have figured out a way to ensure that tech geeks around the world will continue to have gold to use in their electronic connectors. If you didn't know, all of those 1000-2000 pins on a modern CPU are coated in gold, along with the pins in expansion slots on the motherboard.
Professors Kazem Kashefi and Adam Brown utilized the bacteria Cupriavidus Metallidurans to process a naturally occurring toxic gas known as Gold Chloride into 99.9% pure 24-carat gold. You can see the apparatus that was used in the experiment in the above picture. And no, it's not magical.
The bacteria used was discovered to be up to 25 times more resistant to toxic environments than previously thought. This discovery prompted the experiment that resulted in the production of gold. It's a rather simple affair, too. The bacteria is placed into a small bowl into which the toxic Gold Chloride gas is pumped.
Leave it there for about a week and you'll end up with a 99.9 percent pure gold nugget. Unfortunately, it won't be solving any financial problems or making anybody rich anytime soon. While the process is easy, the Gold Chloride gas isn't cheap and since it isn't "natural" gold, it won't be worth as much.
Scientists from the NanoRobotics Laboratory at cole Polytechnique de Montreal in Canada have discovered a way of directing nanobots (nano-sized robots) inside the human body. If you're unfamiliar with nanobots, the nano-sized robots are so small that they can only be seen under a microscope.
These bots can be guided toward specific parts of the body that were too dangerous to risk surgery over - and is considered a huge breakthrough in cancer treatment. The technology is still in its infancy, with human testing not even a thought for now, but there are a few robotics firms including Quantum International, Intuitive Surgical, iRobot Corporation, and Dover Corporation, who are all committed to pushing this nanobot technology.
Robert Federowicz, CEO of Quantum, has said:
Using robots to deliver cancer-killing medicine directly to a tumor deep within the body could forever change the treatment of the disease. The market for such astonishing technology would obviously be enormous. Quantum is dedicated to bringing just such innovations out of the laboratory and into the global marketplace.
In the infamous words of Dr. Evil, the earth is filled with "liquid hot magma." Now, some scientists are looking to drill down into the inner filling of our Earth to do more studying. This is no easy task as the people who have attempted it before will tell you. The price tag will be at least $1 billion USD, with no guarantee of success.
The group of international scientists plan to drill into the mantle in one of three places. The three options are located in the Pacific ocean, along mid-ocean ridge lines where the crust is the thinnest due to the quick forming of said lines. Here, the crust is believed to be as thin as 6km, whereas other parts of Earth have up to an 80km thick crust.
This isn't the first attempt at drilling into the mantle of the Earth. Russia attempted something similar with the Kola Superdeep Borehole, which managed to drill as deep as 12km, though not in the middle of the ocean. "It will be the equivalent of dangling a steel string the width of a human hair in the deep end of a swimming pool and inserting it into a thimble 1/10 mm wide on the bottom, and then drilling a few meters into the foundations."
One of my greatest fears are injections - I don't fall onto the floor, ball up and cry - but I just hate them. I always expect they're going to bring me a world of hurt, and I can't wait for the day when this relatively primitive technology is replaced, well, my wishes are slowly coming true.
Scientists from the Seoul National University in South Korea are hoping to help people like myself, but replacing the sharp metal of an injection, with laser-powered injections - frickin' lasers! A paper published in the Optical Society's Optics Letters journal states that the new method uses laser pulses to create a precisely controlled stream, which is said to be around the width of a human hair - much more manageable.
The injections would then target the epidermal layer, which is a portion of the skin that has no nerve endings, which would create something researcher Jack Yoh calls a "completely pain-free" experience. The high-pressure steams are capable of delivering whatever the injection is being used for, without damaging skin tissue. Yoh spoke with the Optical Society, where he explains:
The impacting jet pressure is higher than the skin tensile strength and thus causes the jet to smoothly penetrate into the targeted depth underneath the skin, without any splashback of the drug.
