    Soft robots typically have squishy bodies and limbs so that they can squeeze into the tightest spaces. If they're to be used for search and reconnaissance missions, though, they'll need to be able to navigate rough terrains. A team of engineers from the University of California San Diego have created a soft robot that can do just that. They made a four-legged machine that can not only wriggle into confined spaces, but also climb over obstacles and walk on sand, pebbles, rocks and even inclined surfaces. The team's secret? A high-end 3D printer that can print soft and rigid materials together.

    A team of researchers in California gathered a few blind mice, not to see how they run, but to find a cure for their glaucoma-like condition. By the end of the experiment, the rodents regained part of their eyesight, making this the first time scientists restored "multiple key aspects of vision in mammals." Glaucoma affects around 70 million people worldwide and currently has no cure. People afflicted with the illness have busted optic nerves -- their retinal ganglion cells' axons had been damaged or severed.

    We've seen nanobots do some neat stuff so far (aquatic dance routines immediately come to mind), but them administering drugs inside a living organism's been the stuff of scientists' dreams. Researchers at the University of California San Diego, however, recently made it a reality by successfully administering acid-powered, zinc-based, self-destructing micromotors inside living mice. The ultra-tiny 'bots measured in at 20 micrometers long, roughly a human hair's width, and are tough enough to survive the harsh gastrointestinal environment autonomously. What's more, they destroy themselves without leaving any traces of harmful chemicals behind and being self-propelled apparently was a factor in "greatly improved" tissue penetration and drug retention. As the BBC points out, this would make them great for treating maladies like peptic ulcers and other stomach disorders.

    What you see here, dear readers, is the image of a fiber-coupled monocentric lens camera that was recently developed by engineers from the University of California, San Diego. The researchers involved in the project say this particular miniature wide-angle lens is one-tenth of the size of more traditional options, such as the Canon EF 8-15mm f/4L pictured above. Don't let the sheer magnitude (or lack thereof) of this glass fool you, however: UCSD gurus note that the newly developed optics can easily mimic the performance of regular-sized lenses when capturing high-resolution photos. "It can image anything between half a meter and 500 meters away (a 100x range of focus) and boasts the equivalent of 20/10 human vision (0.2-milliradian resolution)," according to engineers. As for us, well, we can't wait to see this technology become widely adopted -- don't you agree?

    Interested in upgrading your eyeballs? Well, a team of DARPA-funded researchers led by Joseph Ford of UC San Diego recently published a proposal for a new type of telescopic contact lens in Optics Express. Designed for people with age-related macular degeneration, the lenses are only 1.17mm thick and can magnify images up to 2.8 times. Their layered construction admits light near the outer edge of the lens, bouncing it across a series of tiny aluminum mirrors before transmitting it to the back of the retina, kind of like the origami-optics lens. Telescopic sight can be toggled on and off by using a pair of 3D glasses to switch the polarization of the central part of the lens. It sounds promising, but the lenses -- pictured after the break -- currently have some obstacles, like gas-impermeable materials unsuitable for long-term wear and sub-par image quality.

    Researchers at the University of California San Diego have devised new algorithms that could cut lithium-ion battery charge times in half, help cells run more efficiently and potentially cut production costs by 25 percent. Rather than tracking battery behavior and health with the traditional technique of monitoring current and voltage, the team's mathematical models estimate where lithium ions are within cells for more precise data. With the added insight, the team can more accurately gauge battery longevity and control charging efficiency. The group was awarded $415,000 from the Department of Energy's ARPA-E research arm to further develop the algorithm and accompanying tech with automotive firm Bosch and battery manufacturer Cobasys, which both received the remainder of a $4 million grant. Wondering if the solution will ever find its way out of the lab? According to co-lead researcher Scott Moura, it'll see practical use: "This technology is going into products that people will actually use." Update: UC San Diego reached out to let us know that they were awarded $415,000 (not $460,000 as previously noted) out of a grant totaling $4 million (not $9.6 million), split between Bosch and Cobasys. We've updated the post and the press release below to reflect the correct figures.

    Google is well-known for projects with unexpected origins. It's almost natural, then, that the code Google used to build a web course has led to a full-fledged tool for online education. The open-source Course Builder project lets anyone make their own learning resources, complete with scheduled activities and lessons, if they've got some skill with HTML and JavaScript. There's also an avenue for live teaching or office hours: the obligatory Google+ tie-in lets educators announce Hangouts on Air sessions. Code is available immediately, although you won't need to be grading virtual papers to see the benefit. A handful of schools that include Stanford, UC San Diego and Indiana University are at least exploring the use of Course Builder in their own initiatives, which could lead to more elegant internet learning -- if also fewer excuses for slacking.

  • Optical 'diode' lends hope to photonic computing, rayguns

    The trouble with pesky Photon, at least as far as ultra-fast optical computing is concerned, is that he keeps coming back. If a data-carrying beam of light collides with reflections bouncing around between the components of a chip, it can suffer enough interference to make people yearn for the good old days of electrons. What's needed is the optical equivalent of a diode, which only allows light to pass one way, and that's exactly what researchers at Caltech and the University of California claim to have developed. As you'll see in the photo after the break, their metallic-silicon optical waveguide allows light to travel smoothly from left to right, but it breaks up and dissipates any photons traveling in the opposite direction. This is all good, because there's no point having futuristic 50Gbps optical interconnects if our CPUs lag behind. Light up the source link for a fuller explanation.

    The latest must-have piece of technology in the archaeological world? The Kinect. Students from the University of California, San Diego are taking Microsoft's much-hacked peripheral on an archeological dig in Jordan, using the device to help create 3D scans of the site on the cheap. The hack pulls data captured by the Kinect's camera and infrared scanner, turning the information into avatars that can be plugged into virtual worlds. The hack's creator is hoping that it might some day be able to capture information as complex as a buildings or neighborhoods. The first, decidedly less ambitious application is being referred to as "ArKinect," because what's a cool hack without a cool name?

    Finally, an invention John Waters can get behind. When the harbinger of filth brought the odiferous experience to screenings of Polyester, he took the scratch-and-sniff route -- including scents like glue and feces -- now a team of researchers at the University of California in San Diego are expanding on the smell-what-you-see concept, albeit in a much more high-tech fashion. In collaboration with the Samsung Advanced Institute of Technology, the team has developed a method for generating odors that could pack the appropriate hardware into a device "small enough to fit on the back of your TV." Basically, scents are produced by an aqueous solution, like ammonia, which is heated by a thin metal wire, and eventually expelled, as an odorous gas, from a small hole in its silicone elastomer housing -- and, bam! You've got Smell-O-Vision. The team has tested its method using perfumes by Jennifer Lopez and Elizabeth Taylor, but have yet to create a working prototype. For the sake of innocent noses everywhere, let's hope Mr. Waters doesn't get a whiff of this.

  • Moneta Onyx phase-change memory prototype can write some data 7x faster than traditional SSDs

    As file sizes for many data types continue to grow, smaller chunks are also becoming more ubiquitous, particularly on social media sites like Twitter and Facebook, and search tools like Google. These high-volume, small-size blocks of data may soon be served up from a specific type of SSD, like the Moneta Onyx prototype developed by a team at the University of California, San Diego. Onyx uses phase-change memory (PCM), which can rewrite single bits of data (1s and 0s) on demand, rather than rewriting data in larger chunks, yielding sustained 327 megabyte per second (MB/s) reads and 91MB/s writes with smaller file types -- two to seven times faster than the most efficient commercial SSDs. PCM specifically benefits granular data, rather than large files that must be transferred completely (like photos and documents), so the tech is more likely to appear on devices serving up short text-based messages. Traditional SSDs can write larger files faster than the Onyx prototype, though the new drive offers speedier read speeds across the board. It'll be at least a couple years before PCM becomes commercially available, but once (and if) it does, you'll be reading about your coworker's breakfast or college buddy's traffic jam milliseconds faster than before.

  • Hackers can remotely disable your car's brakes, create sensationalist headlines

    We think you're going to be hearing a lot about this one over the next few days... or weeks. A team of researchers at the University of Washington and the University of California San Diego have determined that, with physical access to your car's ECU, a hacker could "adversarially control a wide range of automotive functions and completely ignore driver input -- including disabling the brakes, selectively braking individual wheels on demand, stopping the engine, and so on." For example, the team was able to connect a computer to a car's ODB-II port, access that computer wirelessly, and then disable the brakes in the first car while driving down the road in a separate vehicle. The conclusion is that these in-car systems have few if any safeguards in place and, with physical access, nearly anything is possible. The solution, of course, is to prevent physical access. So, if you see a hacker hanging around in your car looking all shady, or a laptop computer sitting in the footwell that totally wasn't there before, well, you know who to call.

    Well, it's a good thing life comes with an unlimited data plan, as a recent study conducted by the University of California, San Diego has found that Americans consume plenty of gigabytes in the average day. Thirty-four gigabytes, to be specific, which translates to a grand total of of 3.6 zettabytes of information consumed by American households in 2008 (or 3.6 billion trillion bytes). Of course, that doesn't just consist of gigabytes "consumed" the traditional way, but instead encompasses everything from TV (still the leader by a wide margin) to phone calls to newspapers. In terms of time, the study found that Americans spent about 11.8 hours a day consuming information in one way or another, the majority of which was spent staring at a screen of some sort -- and, yes, they did take HD content into account, but its growth apparently hasn't yet resulted in a huge jump in data consumption.

    If you're the kind of person who happens to have a number of LCD HDTV's lying around, we suggest you give University of California, San Diego's Calit2 Visualization Team a ring. Researchers from the group have constructed a three-column, nine-panel 3D display using flat screens from JVC, stereoscopic glasses, and "game PCs with high end NVIDIA game engines." Dubbed NexCAVE, it's a much more inexpensive version of the its projector-powered StarCAVE used for data analysis, although its range is more limited -- on the plus side, however, since this is LCD, it can be used in bright rooms. At 6,000 x 1,500 pixel, the resolution isn't as mind-blowing as we'd hope, but the team is currently building a version for Saudi Arabia's King Abdullah University for Science and Technology (KAUST) that's 7 columns (totaling 21 panels) and 15,000 x 1,500 resolution. If nothing else, any chance we can play Mirror's Edge on this? Video demonstration of the nine-panel rig after the break. [Via PhysOrg]

    By now, you're no doubt well acquainted with the Albert Hubo Einstein robot developed by the mad scientists at KAIST, but some researchers at the University of California, San Diego has also been working on their own Einstein bot for the past little while, and they've now managed to teach it some new tricks. While the bot has previously been able to display a full range of expressions through some pre-programmed facial movements, it's now able to teach itself how to smile or display other emotions thanks to a new trial-and-error technique dubbed "body babble." That apparently works by comparing Einstein's attempts at an expression with some facial recognition software, which provides Al with some positive feedback each time he manages an actual expression. Did we mention there's a video? Check it out after the break.[Via Switched]Update: The folks at UC, San Diego have kindly pointed us towards a bit more background on their Einstein robot, including a video of its pre-self-teaching days, and a couple of behind-the-scenes pics. Head on past the break for one we like to call "Einstein: Behind the Face."
