Cell-sized robots could help find disease within your body
Small robots aren't anything new, from DARPA's insect-sized disaster relief bots to diminutive inchworms powered by humidity. Now, though, researchers at MIT have likely created the smallest robots, yet: Microscopic, cell-sized electronic circuits made of two-dimensional materials that catch a ride on colloids, insoluble particles that stay suspended in liquid or even air.
Scientists find a way to make cells respond to stimuli
Through the use of synthetic biology researchers have been able to program cells to perform unique functions, like produce drugs in response to disease markers. In order to create more complex cellular circuits, several MIT engineers have now found a way to program cells to respond to a series of events.
DARPA wants modular chips for its killer robots
To add smarts to machines, you need to design circuits and chips, a time-consuming and costly business. The US military's skunkworks arm, DARPA, wants to change all that with its new "CHIPS" program. The goal is to put entire circuit boards on modular chiplets, then tile them together to make a device. That would allow feats like "identifying objects and actions in real-time video feeds, real-time language translation, and coordinating motion on-the-fly among swarms of fast-moving unmanned aerial vehicles," DARPA said in a blog post.
Stretchy circuits will make for better wearables and robots
Smart clothing and robots alike might soon get better thanks to a breakthrough from a team of Swiss researchers. They created relatively thin electronic circuits that can be stretched like rubber up to four times their original length in any direction. In addition, it can be cycled that way nearly a million times without cracking or losing conductivity. That makes it perfect for biological sensors, artificial skin, prosthetics or for electronics that can easily be sewn into fabrics.
Learning circuits and programming with the Geek Squad
If you're ever made a gadget purchase at Best Buy, you've likely heard of the Geek Squad: the retailer's in-house fleet of tech support and repair specialists. Well, helping with your hard drive issues isn't all they do. Here at Expand NY, the crew is showing off some of the tools used at Geek Squad Academy events where kids can learn about technology -- from circuits to programming and more. Being the type to roll up our sleeves, we headed over to take a look. Jump down after the break to take a look at the banana-powered piano and video game controlled with a pair of watermelons.
LightUp electronic blocks and AR app teaches kids circuitry basics (hands-on)
There are plenty of kits out there designed to help kids learn the ins and outs of electronics, but LightUp hopes to stand out from the crowd with not just easy-to-use building blocks but an accompanying augmented reality app as well. From resistors and LED modules to light sensors, each block represents a real component that can be attached to each other via magnetic connectors, hopefully creating a circuit in the process. LightUp even offers an Arduino-compatible microcontroller block to help kids start coding -- clip the programming wand to the block, hook it up to your computer, and away you go. What really sets LightUp apart is the aforementioned AR app. Simply snap a picture of your circuit, and the software will let you know what's wrong with it if there's a mistake. If everything's working, it'll display an electrical flow animation atop the picture, showing kids the magic of electricity. We had a go at creating a circuit ourselves, and were delighted at how easy it was. The connectors fit in either direction, and can be attached and reattached with ease. We also saw a brief demo of the prototype application, and sure enough, it showed us when an LED block was placed backwards with an error message -- you can see it in action in the video below.
Bio-chemical circuits may make you a man of a machine
You'd be more than forgiven for not knowing who Klas Tybrandt is. The doctoral student at Linköping University is hardly a household name, but his latest creation may garner him some serious attention. The Swedish scientist has combined special transistors he developed into an integrated circuit capable of transmitting positive and negative ions as well as biomolecules. The advantage here is that, instead of simply controlling electronics, the circuits carry chemicals which can have a variety of functions, such as acetylcholine which the human body uses to transmit signals between cells. Implantable circuits that traffic in neurotransmitters instead of electrical voltages could be a key step in taking making our cyborg dreams a reality. We're already counting down the days till we're more machine than man.
Samsung pushes graphene one step closer to silicon supremacy
Graphene has long-held notions of grandeur over its current silicon overlord, but a few practical issues have always kept its takeover bid grounded. Samsung, however, thinks it's cracked at least one of those -- graphene's inability to switch off current. Previous attempts to use graphene as a transistor have involved converting it to a semi-conductor, but this also reduces its electron mobility, negating much of the benefit. Samsung's Advanced Institute of Technology has created a graphene-silicon "Schottky barrier" that brings graphene this much-needed current-killing ability, without losing its electron-shuffling potential. The research also explored potential logic device applications based on the same technology. So, does this mean we'll finally get our flea-sized super computer implant? Maybe, not just yet, but the wheels have certainly been oiled.
New material brings semiconducting to the graphene party
Scientists at the University of Wisconsin-Milwaukee have cooked up a new graphene-based material that could provide a speed boost for all electronics. We've seen the carbon allotrope turn up in circuitry and transistors before, but the new chemical modification -- graphene monoxide -- is said to be easier to scale up, and most importantly is semiconducting, unlike the insulating or conducting forms that have preceded it. This also means graphene can now provide the triad of electrical conductivity characteristics. The scientists were honest enough to admit the discovery was as much by chance as design, with it coming to light while investigating another material containing carbon nanotubes and tin oxide. We're sure they're not the first to make a discovery this way, we just haven't had time to check the notes to be sure of it.
CircuitLab brings schematic design and sharing to the browser (video)
The designs for all those wonderful Arduino and electronics projects don't create themselves, sadly. No, a person needs to put in time and effort laying out the circuits and carefully arranging the components, often by hand, but sometimes with aid of a software tool. A new player in that field is CircuitLab, a surprisingly full featured app for sketching out schematics and simulating them that lives entirely in the browser. It's also amazingly user friendly and simple for even the novice hobbyist to dive into. Finally, once you've finished with your project you can make the design public and share it with others. Check out the quick intro video after the break and sign up at the source.
Inhabitat's Week in Green: 'Plantscraper' vertical farm, new wave energy and a battery-powered iPhone case
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. Groundbreaking green architecture burst into life in Sweden this week as Inhabitat reported that Plantagon began construction on the world's first 'Plantscraper' vertical farm. We also marveled at artist Yayoi Kusama's dazzling Infinity Mirror Room, which shines with the reflections of thousands of LEDs, and we shared the bubbly modular AMPS living wall system. Meanwhile, the MoMA PS1 Young Architects Program announced that HWKN's bright blue spiky sea-urchin shaped pavilion will be popping up this summer, PinkCloud.DK unveiled plans to transform oil refineries into giant energy positive communities and the UK granted planning commission for its first amphibious house.We also showcased several amazing applications for LEGO bricks this week: a NYC apartment renovated with 20,000 plastic bricks, a gigantic LEGO-inspired church in the Netherlands and a remarkable fully articulated prosthetic LEGO arm. Speaking of next-gen prosthetics, this week Israeli scientists demoed a real-life "Star Trek" VISOR that enables the blind to see, and Nike took the wraps off a prosthetic running sole for amputee triathlete Sarah Reinertsen.This also marked a heated week for energy news as solar power heavyweight Sunpower sued Solarcity over stolen data, and Aquamarine Power geared up to connect its new wave energy generator to the UK's national grid. We also got ready for rough days ahead with the waterproof, armageddon-ready, solar-charged, battery-powered iPhone case, and we got things cooking with Biolite's brilliant new camping stove, which converts waste heat into electricity for USB gadgets. Last but not least, we were wowed by several amazing new applications for discarded tech: Sean Avery's astounding animal sculptures made from shattered CDs and Paola Mirai's elegant jewelry fashioned out of discarded computer circuits.
Rambus, Broadcom sign licensing deal, agree to share toys
It never hurts to stop arguing, hug it out and agree on a patent licensing deal. Today, Rambus -- which filed a complaint against Broadcom with the International Trade Commission in 2010 -- signed a licensing deal that resolved those claims. In the statement, Rambus said it will license its patent for integrated circuits used in chips made by Broadcom. The company didn't disclose any financial details related to the deal or which technology would be part of the agreement. However, given that Broadcom's known for its wireless networking chips often found in WiFi, Bluetooth and cellular-capable devices, it seems likely to be in the wireless realm. In other news, Rambus and Broadcom have added each other as Xbox Live friends and gotten to level 36 in Modern Warfare 3 co-op gameplay.
MIT slinks into a cafe, orders a side of photonic chips on silicon
Whiz-kids the world over have been making significant progress on the development of photonic chips -- devices that "use light beams instead of electrons to carry out their computational tasks." But now, MIT has taken the next major leap, filling in "a crucial piece of the puzzle" that just might allow for the creation of photonic chips on the standard silicon material that underlies most of today's electronics. Today, data can travel via light beams shot over through optical fibers, and once it arrives, it's "converted into electronic form, processed through electronic circuits and then converted back to light using a laser." What a waste. If MIT's research bears fruit, the resulting product could nix those extra steps, allowing the light signal to be processed directly. Caroline Ross, the Toyota Professor of Materials Science and Engineering at MIT, calls it a diode for light; to construct it, researchers had to locate a material that was both transparent and magnetic. In other words, a material that only exists in the Chamber of Secrets. Hit the source link for the rest of the tale.
Sony's Tablet S goes under the knife, reveals secrets lurking within
With the Tablet S on sale, it was really only a matter of time before its inevitable teardown, and here to fill our need for splayed circuity is one from TechRepublic. Seeing as most Honeycomb tablets have similar internals, there aren't too many surprises to be had, but the outfit did curiously find a hole for a cellular modem, as well as an easy to replace battery and an internal plastic frame that adds rigidity (pictured above). If you're ready for 74 photos of the slate being torn asunder from every possible angle, a source link awaits you below -- if not, can we humbly recommend our preview? [Thanks, Bervick]
Researchers wed quantum processor with quantum memory, quaziness ensues
Quantum computing has a long way to go before becoming truly mainstream, but that certainly hasn't stopped us from indulging in dreams of a qubit-based existence. The latest bit of fantasy fodder comes from the University of California, Santa Barbara, where researchers have become the first to combine a quantum processor with memory mechanisms on a single chip. To do this, Matteo Mariantoni and his team of scientists connected two qubits with a quantum bus and linked each of them to a memory element, capable of storing their current values in the same way that RAM stores data on conventional computers. These qubit-memory links also contained arrays of resonators -- jagged, yet easily controlled circuits that can store values for shorter periods of time. The qubits, meanwhile, were constructed using superconducting circuits, allowing the UCSB team to nestle their qubits even closer together, in accordance with the von Neumann architecture that governs most commercial computers. Once everything was in place, the researchers used their system to run complex algorithms and operations that could be eventually used to decode data encryption. The next step, of course, is to scale up the design, though Mariantoni says that shouldn't be too much of a problem, thanks to his system's resonators -- which, according to him, "represent the future of quantum computing with integrated circuits."
IBM outs integrated circuit that's made from wafer-size graphene, smaller than a grain of salt
Lest you don't care what your circuits are made of, listen up: graphene's the thinnest electrical material, comprising just a single atomic layer. In addition to its electrical, thermal, mechanical, and optical properties, researchers dig it because it has the potential to be less expensive, more energy-efficient, and more compact than your garden-variety silicon. So imagine IBM's delight when a team of company researchers built the first circuit that fits all the components, including inductors and a graphene transistor, on a single wafer -- a setup that consumes less space than a grain of salt. The advantage, scientists say, is better performance than what you'd get from a circuit combining a graphene transistor with external components. In fact, the researchers got the circuit's broadband frequency mixer to operate at 10GHz , a feat that could have implications for wireless gadgets running the gamut from Bluetooth headsets to RFID tags. That's all just a layman's explanation, of course -- check out the latest issue of Science for the full paper in all of its technical glory.
Researchers build synthetic synapse circuit, prosthetic brains still decades away
Building a franken-brain has long been a holy grail of sorts for scientists, but now a team of engineering researchers have made what they claim to be a significant breakthrough towards that goal. Alice Parker and Chongwu Zhou of USC used carbon nanotubes to create synthetic synapse circuits that mimic neurons, the basic building blocks of the brain. This could be invaluable to AI research, though the team still hasn't tackled the problem of scope -- our brains are home to 100 billion neurons, each of which has 10,000 synapses. Moreover, these nanotubes are critically lacking in plasticity -- they can't form new connections, produce new neurons, or adapt with age. All told, the scientists say, we're decades away from having fake brains -- or even sections of it -- but if the technology advances as they hope it will, people might one day be able to recover from devastating brain injuries and drive cars smart enough to avert deadly accidents.
Researchers develop programmable molecular circuitry for living cells
Researchers at the UCSF School of Pharmacy's Department of Pharmaceutical Chemistry, led by Christopher A. Voigt have just published a paper which promises to get your circuits moving. The team has been working with E. coli bacteria to build logic gates like the ones found in computers directly into cells, making it possible to rewire and program them. The simple logic gates used in the experiment were built into genes then inserted into E. coli cells. The logic gates then acted as the communicator between the separate strains, allowing them to be connected together.The use of logic gates in cells could make it possible to tackle more complicated processes, so that science can begin to use cells at the molecular level for biomedical advances.
Nendo's ceramic circuit board speaker gives the rest of the audio world body image issues
We've seen slick hand-crafted ceramic speakers in the past, but this one millimeter-thick collaboration between potter Mitsuke Masagasu and design firm Nendo is in a different league. An entirely different league. The set is result of the so-called Revalue Nippon Project, created by Japanese footballer Nakata Hidetoshi to revive traditional Japanese art forms. Nakata selected five curators -- in this case the director of the 21st Century Museum of Contemporary Art in Kanazaw -- who were then tasked with pairing a ceramicist and designer to collaborate on a one of a kind form. Not satisfied with simply being 31 times thinner than the emaciated Mythos XTR series as a sole basis for artistic impact, the speaker's ravishing circuit design is also made without a human touch. Instead, a computer-controlled process cuts thin slices from a ceramic substrate slab, fixes them with mercury vapor, and then mounts them via a robotic arm. Amazingly, sound quality is still also touted as being top notch. There are no plans however for these speakers to ever be mass produced, so if you were hoping to snag one as the ultimate accessory for your über-modern flat... well, let yourself down easy, alright champ? %Gallery-108170%
Intel plans to shrink its Atom chip circuits to just 15 nanometers, and other glorious tales of wonder
Earlier this week at IDF Intel dropped some very, very tiny news on us... namely that the Atom SoCs will soon include circuits which are 22 and 15 nanometers in size. The smaller, 15 nanometer width is the size of about 60 atoms -- seriously. Intel's processors, which are categorized by the size of their circuitry, are currently 32 nanometers at their smallest. So, we'd say you should be on the lookout for them but... yeah, well, you know where we're going with this.
