Researchers at UC Santa Barbara made a simple neural circuit comprised of 100 artificial synapses, which they used to classify three letters by their images, despite font changes and noise introduced into the image. The researchers claim the rudimentary, yet effective circuit processes the text much in the same way as the human brain does. In other words, like you're currently interpreting the text in this article. Even if you change the font, printscreen this article and splash it with an airbrush in MS Paint, you'll still be able to read at least portions of it, because the human brain is so great at scaling patterns and abstracting symbols. This kind of research will hopefully usher in a new age of more refined, energy efficient computing.
Printing your own mechanical parts or toys is really easy, not to mention fun, using a 3-D printer. But things get a bit trickier when you want to print the kind of parts that go into a car or airplane. Metal is a lot more complex to work with inside a 3D printer than polymers like ABS - the kind of film roles that get melted layer by layer to form a part of your liking once it cools down. Engineers at General Electric just demonstrated, however, that in practice it's not that complicated to print parts out of metal alloys as it sounds. The team used additive technology to build a fully functional jet engine, then test powered it to 33,000 RPMs. The company is already using 3-D printed fuel nozzles in its next-generation aircraft engines, slated to role out in 2016.
Mobile technology is revolutionizing nearly everything consumers do. From browsing price comparisons in the store to checking movie times for nearby theaters while you’re still on the road, it’s possible to streamline virtually every activity using your smartphone. Dining is one of the most recent additions to the world of mobile conveniences.
Next Thing Co, a fledgling company started by three budding hardware enthusiasts, just released a KickStarter campaign in which they promise to release a computer worth nine USD. The computer, called CHIP, can do everything 90% of all people usually use computers for: office apps, surf the web and play games. The team hoped to raise $50,000 to supplement their own budget and start rolling orders at an assembly line in China. Right now, $1,040,006 were donated as I'm writing this and the numbers are swelling with 24 days still to go. Are we finally seeing the fruits of liberalizing computing and economics of scale?
Climate models and environmental monitoring missions are ever more reliant on autonomous underwater vehicles (AUVs) to scour the ocean depths and bring back valuable data like temperature, salinity, carbon levels and so on. Researchers at MIT have now upgraded the way AUVs perform their missions by adding an extra dimension to their autonomy. They demonstrate how a pack of AUVs, directed by a "captain" drone, is able to navigate obstacles and retrieve data with minimal intervention. This dramatically enhances performance and might revolutionize the way scientists study the oceans.
It generates as much oxygen as 400,000 square feet of natural woodland, it looks nice, and it can produce lots of biomass – the Urban Algae Canopy is a concept we should probably pay more attention to. It combines biology, modern architecture and electronics, creating a structure that not only generates energy, but also adapts and […]
Even the best chess players are no match for computers these days, but computers are still struggling when it comes to games that have a random or unknown component. In games like Bridge or Poker, humans still hold the crown. Scientists from the Carnegie Mellon University tried to change that, by designing Claudico - a computer program built to defeat humans. But Claudico lost, badly.
A few years ago, NASA unveiled one of the most interesting technologies I've seen recently - a portable radar unit based on technology used to detect alien life on other planets. Now, the first time this technology has been used in the field, it managed to find 4 people buried under meters of rubble, by detecting their heartbeat.
Scientists have managed to use a simple smartphone to test for blood parasites; the device and app was successful in small trials in Cameroon.
One of the most famous NSA whistleblowers (or the 'original NSA whistleblower'), William Binney, said the agency is collecting stupendous amounts of data - so much that it's actually hampering intelligence operations.
Physicists at the Pacific Northwest National Laboratory used 3D printed materials and a simple glass bead to create a magnifying system that works with your smartphone's or tablet's built-in camera to magnify matter 100x, 350x or 1,000x. The whole system costs only 1$ to manufacture.
About a month ago, we were telling you about a new battery for houses Tesla was working on, that might revolutionize home energy and bring forth massive change in renewable energy - now, the official announcement is out. Homeowners will be able to get the Powerwall battery, in 7 or 10 kilowatt modules, which will cost $3000 and $3500 respectively.
Microsoft demonstrated just how far they’ve come with their augmented reality HoloLens project – and it’s far. Virtual browsers on your wall, virtual dogs, the weather in your cup, holograms following you to the kitchen… all that and many more were showcased by Microsoft at the Build Conference. I’ll be honest with you, I didn’t […]
Since 1990, Keith Londsdale went through no less than 45 different surgical procedures to remove basal cell carcinoma tumors, one of the most common skin cancers. The man survived the ordeal, but was left deformed as doctors had to remove his nose, upper jawbone and cheekbones. Basically, the 74-year-old-man now has a huge hole in his face.
Each year, hundreds of millions people fly by plane to meet family, do business or travel for leisure. Quite a feat, considering humans don't have any wings. Like all advanced technology we have at our disposal today, flying is also taken for granted. In the early days, however, just getting a few feet off the ground for a couple of seconds was considered a triumph. Like human pioneering flight, nature also had to experiment a lot before flying creatures could evolve. One newly discovered dinosaur species fits well into this story. Unearthed in 160 million year old sediments in China, this queer dinosaur strangely had bat-like wings. It's uncertain however if it was able to fly or even glide, owing to the degraded state of the fossil records. One thing's for sure, it makes the evolution of flight much more interesting to study.
Boom!
Each year, we cut down 26 billion trees, for lumber, agriculture, mining and development projects. Every year, we plant about 15 billion trees, so that still leaves us with a huge deficit - something which is not sustainable and has to be addressed as soon as possible to avoid further problems down the road. Now, a former NASA engineer has found that drones could play a key part, and he plans to plant up to 1 billion trees a year using them.
IBM claims to be one step closer to developing functional, scalable quantum computers. According to the company, they managed to overcome two key hurdles, demonstrating for the first time a new, square quantum bit circuit design - the only physical architecture that could successfully scale to larger dimensions.
A report issued by a committee at MIT concludes that the decline in science funding will have drastic consequences for the country's economy and security, making the US trail behind other countries like China which is spending immense amounts of money on science. In fact, one study estimates China will become the world's leading science and innovation producer by 2020, outpacing the US. The MIT report identifies some 15 fields where inadequate budgets seriously hampers progress, from Alzheimer's research, to nuclear fusion, to disease and agriculture.
It's common sense - in order to brush your teeth, you need water, a toothbrush, and toothpaste. Well, a company from Japan wants to change all that: they've developed a nanotechnology toothbrush that basically eliminates the need for toothpaste.
The US Department of Energy (DoE) has sealed a deal with Intel worth $200 million to build what's supposed to be the world's most powerful computer in 2018: the Aurora. The behemoth will be based on a next-generation Cray supercomputer, code-named “Shasta,” and will use Intel’s HPC scalable system framework. Aurora will likely reach a peak performance of 180 petaflop/s, or 180 quadrillion floating point operations per second (completed algorithm action, not just instruction). For comparison, a 2.5 GHz processor has a theoretical performance of 10 billion FLOPS.
Researchers from the University of Cambridge in England claim to have unraveled one of the great mysteries of electromagnetism, and believe their work in ultra-small antennas could not only revolutionize global communications, but also explain some of the tricky areas where electromagnetism and quantum physics overlap.
What happens when NASA and IBM sponsor a hackathon and offer their infrastructure to 10,000 researchers, coders, entrepreneurs end educators? Well, I'm not really sure... but it's definitely gonna be something awesome.
The future is here - scientists at a Polish company have developed a liquid body armor. Technically speaking, it's a non-Newtonian shear-thickening fluid (STF) that is lighter than current body armor materials, and might resists the impact better than Kevlar.
Tomorrow's bridges, tunnels and other engineering structures might be built with a different type of "smart" concrete: Belgian researchers at the University of Ghent have created a self-repairing type of concrete.
With the advancements in 3D printing, it only seems like a matter of time until it starts to actively affect our lives. Especially prosthetics may be revolutionized by 3D printing, as we've already seen time and time again. Now, a group of dentists believe they can 3D print teeth using a simple and cheap technique, only taking a few minutes for it.
What do fires and deep sounds have in common? Not much right now, but they might have a lot in the future.Two George Mason University students have designed a device that uses sound waves to put out fires, thus potentially eliminating the need for carrying around huge quantities of water and costly cleaning operations. Here's how it works:
Tesla Motors are out to change the world - and they're doing it fast, and in style. Like many other of their projects, this one seemed to pop up out of nowhere: Tesla have designed a battery that can power your home and even larger utility buildings. In other words - it could take your house out of the grid.
China is the largest polluter in the world at the moment, and they’re also reaping what they sew. But you can’t accuse the Chinese for not trying to right their ways – at least some of them; in an effort to mitigate the ridiculous amounts of smog that clouds some of China’s cities, scientists have […]
Boeing, a major aircraft and military manufacturer, just secured a patent that describes a Star Trek-like force shield, meant to protect vehicles operating in war zones. I love it when engineers are inspired by science fiction - it means that the authors really did a great job, not only at foreseeing the future, but also in offering the incentive to bring these sort of contraptions to real life.
While in South American during his 1830 expedition with the HMS Beagle, Charles Darwin came across the fossils of two peculiar hoofed species which he was unable to classify properly. One was Macrauchenia, which looked like a camel with the head of an ant eater, and the other was Toxodon which had the body of rhino, the head of a hippo and the teeth of a rodent. So, was the Macrauchenia related to the camel or the ant eater? Who was Toxodon's closet cousin, the hippo or the rhino? Darwin was puzzled and to no avail concluded these were “perhaps one of the strangest animals ever discovered”. But Darwin didn't have the tools we have today. Now, using a ground breaking technique researchers have sequenced the collagen of a myriad of South American mammals, including Darwin's 'strangest animals' and finally found their real taxonomy.
Long before T-rex claimed the top dog spot among terrestrial predators, a vicious crocodile ancestor that walked on its hind legs was at the top of the food chain during the Triassic. The fossils of the Carnufex carolinensis, also known as the the “Carolina Butcher,” were discovered decades ago in the Pekin Formation, a geological formation in North Carolina's Chatham County. It was only recently that researchers reanalyzed the fossils and concluded they were dealing with an all new predator that roamed the Earth several million years before dinosaurs were even around.
This is it - the pinnacle of technological development, the result of countless research hours; yes, it's a tree.
A rather surprising study found that graphene's imperfections can actually be used to improve fuel cell efficiency. Researchers from Northwestern University worked together with scientists of five other institutes to show that defective graphene actually works as the world's thinnest proton channel—only one atom thick.
In a rather intriguing tweet, Tesla Motors and SpaceX CEO Elon Musk announced that he will end 'range anxiety' by the end of the week for the entire S series. The electric Tesla Model S is already able to travel up to 265 miles before its battery runs out of power – one of the longest driving ranges of any electric car currently on the market. Now, it seems they are preparing to take things even further.
Half cockroach, half machine, these peculiar insects were hijacked by researchers at Texas A&M University for science. Electrodes implanted in their tiny brains send electrical signals that stir the roaches left, right or makes them halt. Effectively, the researchers are controlling their bodies. This may sound despicable - it actually is in many ways - but the benefits to humanity are far reaching. The cyborgs would be our eyes and ears in places otherwise inaccessible, like disasters sites in the wake of earthquakes or other environmental calamities. Picking the cockroach brain might also help us learn more about how our own brain works. This in turn could spur the development of brain-computer interfaces or a new generation of prostheses that faithfully mimic real limbs.
A new company called Carbon3D, founded by a team of physicists and chemists, were inspired by the iconic Terminator villein, the self-morphing T-1000, to build a machine that 3D prints objects from a puddle of raisin. Unlike conventional 3D printers which add material layer by layer, the latest innovation works fundamentally different. The models it prints are extremely sophisticated and detailed, making it a valuable tool for consumer products, not just prototyping as is the norm today.
About two dozen University of Texas students gathered on Saturday at the entrance to the SXSW tech and entertainment festival to voice their concerns about the risks artificial intelligence might pose to humanity. Though largely ignored by hipster pedestrians nearby, the protest does raise some legitimate concerns even though technology is still far off from any Skynet scenario. Thankfully, we might never cross this SciFi threshold.
Researchers at Brown University have found a cheaper and easier way to create hybrid perovskites, enabling engineers to develop more affordable and efficient solar cells. Perovskite is a calcium titanium oxide mineral composed of calcium titanate (CaTiO3). The mineral has received much attention in recent years as artificial perovskite crystals have increasingly been used in solar cells. Perovskite films in solar cells are excellent light absorbers, but they until now, they were more expensive to fabric and only created small crystals.
NASA has announced its plans to implement smart glasses in their future missions. The space agency will work together with Osterhout Design Group (ODG) in order to develop the technology which will be used for virtual reality and augmented reality applications during human spaceflight, including repairs and other technical tasks.
It's awesome when engineers can take inspiration from nature and design something truly spectacular - now, a Berkeley team has managed to create a material that can shift colors as easy as a chameleon's skin when pulled or twisted. The material could be used for camouflage or for the next generation of display technologies.
The technology of 3D printing has reached an interesting point in its trajectory. It's been around for years, lots of people know it exists and it has even reached the high street. However, there's still something of a gap between its promise and the reality, and it looks like the general public are yet to be convinced. So perhaps now is a good time to take stock of 3D printing: its history and its future.
A team at Caltech has devised a new film coating that facilitates catalysis and electron transfer in a solar powered system that splits water into hydrogen and oxygen, which can be used as fuels. Such a system is also called an artificial leaf or solar-fuel generator because in many ways it mimics the process which plants use to convert sunlight and CO2 into oxygen and fuel (sugars, carbohydrates). The researchers make note, however, that they're still a long way from making it commercial viable, but these sort of updates are inspiring.
Switching massively to electric cars could save UK drivers up to £1,000 a year on fuel costs, reducing oil imports by almost half by 2030; a similar trend could be replicated in other countries in Western Europe or in the US.
Some people waste hours each day driving their car, time they could have otherwise spent better. You'll still be trapped on the road in a self-driven car, but the added benefit is that you'll be free to do other stuff - anything but stare into your windshield non-stop. According to a study made by McKinsey & Company, self-driving cars could generate billions of dollars a year in revenue from mobile internet services and products, even in situations where occupants only save a couple of minutes. Of course, we had it coming. What did you thought people would do with their spare driving time? Surf the internet, of course.
A private company in Hong Kong known as the Hong Kong Nicaragua Canal Development Investment Company (HKND) has been given the green light to start the $50 billion work on a canal that will connect the Pacific and the Atlantic Ocean through Nicaragua. The project, which will be significantly longer than the Panama canal could bring huge economic benefits, saving a lot of time and resources, but it also raises major environmental concerns.
Scientists at the University of California, Santa Barbara, and at Google reported on Wednesday in the journal Nature that they are one step closer to developing a true quantum computer - they have developed a quantum device the art of checking and correcting its own errors.
A crowd gathered for the New America Foundation’s first annual Future of War conference was told by DARPA's director that a woman was able to control F-35 flight simulator without touching the joystick. The woman controlled the simulation only with her thoughts, which were relayed and processed to the simulator by a neural implant embedded in her left cortex.
If you've ever wondered what happens inside an egg, then science has you covered - researchers have developed transparent artificial eggshells; but they didn't do this just out of curiosity - they want to create a controlled environment for bird embryo growth and development to aid stem cell studies.
Scientists at the University of Sydney in Australia have achieved 5G speeds of 1Tbps, far exceeding existing the speeds of existing technologies. At 1 Terrabyte per second, you could download 10 movies per second.
