NASA’s Quantum Artificial Intelligence Laboratory (QuAIL) is the space agency’s hub for an experiment to assess the potential of quantum computers to perform calculations that are difficult or impossible using conventional supercomputers.
NASA’s QuAIL team aims to demonstrate that quantum computing and quantum algorithms may someday dramatically improve the agency’s ability to solve difficult optimization problems for missions in aeronautics, Earth and space sciences, and space exploration.
The hope is that quantum computing will vastly improve a wide range of tasks that can lead to new discoveries and technologies, and which may significantly change the way we solve real-world problems.
Beginning with the D-Wave Two™ quantum computer, NASA’s QuAIL team is evaluating various quantum computing approaches to help address NASA challenges. Initial work focuses on theoretical and empirical analysis of quantum annealing approaches to difficult optimization problems.
MDS Robot with Human Expressions Abilities
We are developing a team of 4 small mobile humanoid robots that possess a novel combination of mobility, moderate dexterity, and human-centric communication and interaction abilities. Our collaborators include Xitome Design and UMASS Amherst. We refer to this class of robots as “MDS” for Mobile/Dexterous/Social. Completion is targeted for fall 2007.
The purpose of this platform is to support research and education goals in human-robot interaction, teaming, and social learning. In particular, the small footprint of the robot (roughly the size of a 3 year old child) allows multiple robots to operate safely within a typical laboratory floor space. MIT is responsible for the overall design, the mobile manipulator is developed by UMASS Amherst, and system integration is handled by Xitome Design.

Scientists achieve reliable quantum teleportation for first time
Einstein is wrong? That’s the potential outcome of a quantum mechanics study as scientists race to disprove his views on entanglement.
Albert Einstein once told a friend that quantum mechanics doesn’t hold water in his scientific world view because “physics should represent a reality in time and space, free from spooky actions at a distance.” That spooky action at a distance is entanglement, a quantum phenomenon in which two particles, separated by any amount of distance, can instantaneously affect one another as if part of a unified system.
Now, scientists have successfully hijacked that quantum weirdness — doing so reliably for the first time — to produce what many sci-fi fans have long dreamt up: teleportation. No, not beaming humans aboard the USS Enterprise, but the teleportation of data.
Physicists at the Kavli Institute of Nanoscience, part of the Delft University of Technology in the Netherlands, report that they sent quantum data concerning the spin state of an electron to another electron about 10 feet away. Quantum teleportation has been recorded in the past, but the results in this study have an unprecedented replication rate of 100 percent at the current distance, the team said.
Thanks to the strange properties of entanglement, this allows for that data — only quantum data, not classical information like messages or even simple bits — to be teleported seemingly faster than the speed of light. The news was reported first by The New York Times on Thursday, following the publication of a paper in the journal Science.
BLOODHOUND SSC is a unique, high-technology project to design and build a car that will break the 1,000mph barrier and set a new world land speed record. Designed and constructed in the UK, BLOODHOUND SSC includes components and sponsorship from international companies and will make its record attempt in South Africa.
With that charger you can charge every device that uses the usb port to charge like : (mp3 player, iphone,psp’s etc.) my solar charger i put some led’s to be able to use it as a torch).
Step 1: What you will neeed
1) two solar panels from garden lights
2) 4AA rechargable baterys
3) 4AA baterry holder
4) one female usb connector
5) a small button
6) a case
7) some wires
8) three 3.6v led’s
9) two 1n5817 blocking diodes
10) one dpdy 6 pin push switch
11) one 150 ohm resistor
Step 2: Taking the solar garden lights apart
Open the solar light and take the solar panel out of the light. there is a small circuit where you can take the two diodes and also some leds battery that come with the light will be about 800mha. we don’d need that low capacity.The capacity that we need from each baterry has to be about 2000mha).
Energy Production in Space
Whether they’re producing voltage directly from solar rays or focusing them to melt salt like Ivanpah, even Earth’s biggest and baddest solar power plants are hamstrung by all this damnable atmosphere getting in the way. But a new kind of off-world solar energy plant could soon provide the whole planet with plenty of power—we just have to finish figuring out how to build and operate it.
What It Will Take to Farm Sunlight from Space
With the advent of silicon-based photovoltaic solar panels—the kind that directly convert solar energy to electrical current—some 60 years ago, researchers immediately looked to the skies as the ideal place to collect solar energy. Up there, you don’t have miles and miles of atmosphere and clouds absorbing, scattering, or blocking out the sun’s incoming rays. That means photovoltaic panels should, conceivably, be able to operate at (or very near) their theoretical efficiency limits. Plus, if you position a solar power satellite (SPS) properly over the equator, it will only reside in the Earth’s shadow for a few hours every year and thereby provide nearly non-stop energy.
The idea of space-based solar power (SBSP) was formalized in the seminal 1968 report, Power from the Sun: Its Future, by American aerospace engineer Peter Glaser. The paper set forth a conceptual system for collecting unhampered solar energy from massive extra-atmospheric arrays of photovoltaic cells set in geosynchronous orbit above the equator, and transmitting it wirelessly back to Earth where it would be used by terrestrial power grids. In theory, with enough orbiting “solar farms,” the energy needs of not just the U.S. but the entire world could be met.
In his paper, Glaser argued that while building, launching, and operating such a power plant was currently beyond the reach of scientific knowledge at the time, those technological advances would be within our grasp in the coming years and decades. So, are we any closer to freeing the entire world from its energy woes with orbiting solar farms than we were at the start of the Space Age? Sure, but we’ve still got some work to do before that actually happens. Specifically, there are a number aspects that we need to iron out before something like this actually comes to fruition.
“Projects ‘for the 90%’ mostly fall somewhere between two extremes: charity and business,” designer Gabriele Diamanti tells Co.Design. “Neither was my inspiration!” Instead, spurred on by his own extensive travel and friends’ involvement in NGOs, he developed a fascination with global water scarcity as a graduate student at Milan Polytechnic in 2005; he recently decided to pursue his interest again and the result is Eliodomestico, an open-source variation on a solar still.
It functions by filling the black boiler with salty sea water in the morning, then tightening the cap. As the temperature and pressure grows, steam is forced downwards through a connection pipe and collects in the lid, which acts as a condenser, turning the steam into fresh water. Once Diamanti established the fundamentals were sound, he experimented with a series of concepts for the aesthetic of the object. “My goal was to design something friendly and recognizable for the users,” he explains. “The process developed quite naturally to determine the current shape; every detail is there for a reason, so the form, as well as production techniques, represent a compromise between technical and traditional.” Primary field studies in sub-Saharan Africa revealed the habit of carrying goods on the head—also a common practice in other areas around the world—and this was integrated into Eliodomestico’s plan. And while solar stills aren’t a totally new concept, Diamanti says it’s rare to find them in a domestic context rather than in missions or hospitals, or as large plants overseen by qualified personnel that serve entire communities. “I tried to make something for a real household that could be operated directly by the families,” he says.
The project recently won a Core77 Design Award for Social Impact; already, Diamanti has received international feedback, and hopes to see locals adapt and modify the design to take advantage of their own readily available materials and native environments. “The idea is that instructions for the project can be delivered to craftsmen” with the help of NGOs, he says, then a micro-credit program could be established to finance small-scale start-ups specializing in production. “So the NGO is the spark, micro-credit is the fuse, the local craftsmen are the bomb!”
A new material that prevents plastic from aging has been developed by the Commonwealth Scientific and Industrial Research Organization, Australia (CSIRO)—offering significant environmental and cost savings for the energy industry.
When applied to plastic lining this material can clean up exhaust gases from power plants much more effectively than existing methods.
According to CSIRO, the techniques industry use to separate out raw materials such as gases, liquids and solids are extremely energy-intensive, accounting for 40% of the world’s energy use each year.
According to lead author of the study (see footnote) Dr Sam Lau, the new technique offers a solution that will make the separation process a staggering 50 times faster.
“At the moment power generators rely on plastic linings made up of tiny holes just one nanometer wide, a tiny fraction of a width of a human hair,” he said.
“For decades scientists have been trying to improve the efficiency of this process by using plastics with larger holes. However, these larger openings tend to age very quickly and collapse within a matter of days.
“What we’ve done is make use of incredible compact materials known as Metallic Organic Frameworks—or MOF—swhich have the surface area of a football field in just one gram.
“We found that the density of the MOFs acts like a shot of botox and actually freezes the larger holey structures in place for an entire year.”
This suddenly makes the lining with larger holes a viable option for industry, allowing them to complete separation processes at 50 times the speed.
“This is a much more environmentally friendly approach and of course translates into huge cost and efficiency savings for the companies who take this up,” Dr Lau said.
According to Dr Lau, not only does the technique have incredible potential for cleaning up exhaust gases from power plants, it could also be used to enhance the purity of natural gas streams, the separation of water from alcohols (a key process in biofuel synthesis) and for dye removal in the textile industry.
“We’re extremely excited by this discovery and hope to see it being applied commercially within one to two years,” he said.
Scientists have spliced all kinds of material in order to produce new organisms and conduct experiments. For example, scientists at Duke University are currently using genetic modifications to combine polio with the common cold and create an organism that is able to combat brain cancer. As amazing as this sounds, there are other hybrids that are even more perplexing and astounding.
Case in point: At MIT, scientists recently announced that they developed a hybrid material that is a cross between living bacterial cells and non-living material (specifically, gold nanoparticles). Ultimately, the “living material” that results from this combination is able to respond to its environment just like a normal living cell; however, simultaneously, it can conduct electricity and emit light.
This process was started by Timothy Lu, assistant professor of electrical engineering and biological engineering. Lu began by taking E. colibacteria, which produces a protein structures known as “curli fibers,” and adding peptides to the fibers. This process enables the fibers to bond with items (like the gold nanoparticles) that are introduced to the environment.Ultimately, these gold particle-covered fibers formed into rows of gold nanowires, that allowed the biofilm to conduct electricity.
A team of roboticists at MIT is preparing Atlas, a 6-foot-2-inch-tall, 330-pound humanoid robot that can climb stairs, open doors, and even drive a car, for competition in the DARPA Robotics Challenge at the end of 2014.
Atlas is built by Boston Dynamics, the robotics company bought by Google last December, and there are only eight of them in the world.
The DARPA Challenge is a “robot Olympics” — robots are asked to do things like climb a ladder, or connect a firehose to a standpipe and turn on the valve. These tasks are designed to test a robotic system’s “mobility, manipulation, dexterity, perception, and operator control mechanisms.”
A robot that can’t make sense of its world in real time would never be able to do these things. Here’s how Atlas’ sensor systems rise to the challenge.
