ICYMI: Sorting crops with artificial intelligence
try{document.getElementById("aol-cms-player-1").style.display="none";}catch(e){}Today on In Case You Missed It: Google's Tensor Flow machine learning technology helped create a device to sort through massive amounts of cucumbers at a farm in Japan, sorting the vegetables by quality grade so that humans don't have to do it manually. Meanwhile, an Australian scientist created an ink that changes colors when exposed to sunlight, which could theoretically help people from getting a sunburn. We also touched on the new internet-connected pet toy from Acer and rounded up the biggest headlines of the week for you in TL;DR. Be sure to check out IBM Watson's movie trailer and read about SpaceX's rocket explosion.

Fast-charging batteries will power your gadgets for 20 years
Fast-charging batteries are all nice and good, but the lifespan matters, too -- why should you have to replace power packs (or entire devices) every couple of years ? You may not have to give up performance or longevity if researchers at Nanyang Technology University have their way. They've developed new lithium ion batteries that can reach a 70 percent charge in two minutes, but should also last for over 20 years -- several times longer than the cells in your current laptop or smartphone. The trick is using titanium dioxide nanotubes for the anode (the negative pole) instead of graphite; they both speed up the battery's chemical reactions while offering 10,000 charging cycles instead of the usual 500.
UCSB engineers proteins that make silicon, leads hipsters to insist on organically-grown computers
Organic circuits have been in development for awhile, but it's still rare that the organics are producing the circuitry themselves. Researchers at the University of California, Santa Barbara plan to break that silence with genetically engineered proteins that can make silicon dioxide or titanium dioxide structures like those used in the computer chips and solar cells that we hold dear. The trick, the university's Daniel Morse found, is to attach silica-forming DNA to plastic beads that are in turn soaked in the silicon or titanium molecules they're looking for: after some not-so-natural selection for the best genes, the thriving proteins can produce not only substantial minerals, but whole fiber sheets. Much work is left to get the proteins producing the kind of silicon or titanium dioxides that could run a computer or power your house, but the dream is to have synthetic creations that organically produce what would normally need a mining expedition -- imagine something akin to the glass-like Venus' Flower Basket sponge (pictured above) sitting in an Intel factory. We're half-expecting organically-grown smartphones at Whole Foods, right next to the kale chips and fair trade coffee. [Image credit: Ryan Somma, Flickr]
New nanotube battery technology leads to blisteringly fast recharges, improved safety features
Some day, your restroom break may be enough time to charge your [insert nifty gadget here] halfway. A group of researchers at the Department of Energy's Argonne National Laboratory has discovered that nanotubes composed of titanium dioxide can switch their phase as a battery is cycled, gradually boosting their operational capacity. The upshot: laboratory tests showed that new batteries produced with this material could be rejuvenated to 50 percent of their maximum charge in less than 30 seconds. This was accomplished by replacing conventional graphite anodes with titanium nanotube andodes. Following the experiment, lead researcher Tijana Rajh and her colleagues noted that as the battery cycled through several charges and discharges, its internal structure began to orient itself in a way that dramatically improved the battery's performance. Furthermore, using anodes composed of titanium dioxide instead of graphite could improve the reliability and safety of lithium-ion batteries and help avoid scenarios in which the lithium can deposit on the graphite anodes, causing a dangerous chain reaction known as "thermal runaway." Copious amounts of related technobabble can be found in the links below, and there's a video just past the break, too.
5nm crystals could lead to vastly larger optical discs, mighty fine time machines
Blu-ray was already looking mighty fine at 25GB of storage per layer -- and if Sony manages to make the indigo foil sheets hold 33.4GB each, we certainly won't complain -- but Japanese researchers have discovered a compound that could leapfrog Blu-ray entirely. Scientists at the University of Tokyo discovered that by hitting 5-nanometer titanium pentoxide crystals with a laser, they could get the metal to change color and conduct less electricity, leading to what they believe is an effective new medium for optical data storage. At 5nm, the small black crystals could reportedly hold 1,000 times the data of Blu-ray at the same density, and cost less to boot -- the scholars reportedly synthesized the formula simply by adding hydrogen to the common, comparatively cheap titanium dioxide, while heating the compound over a fire. Ahh, nanotechnology -- making our lives easier, one microscopic crystal or tube at a time.
HP touts memristor development, bleak future for transistors
Silicon transistors are the stuff all our dreams of android sheep are made of, but there will ultimately be a limit to how many of them you can squish together inside a processing chip. The progressive avoidance of physical limitations by moving to yet more minuscule dimensions is admirable, but some folks at HP seem to believe the answer lies in a whole different technology. The company has been talking to the New York Times about its memristor (memory resistor) development, which promises to perform both data processing and storage tasks (even without an electrical charge), while also being capable of stacking in a three-dimensional array that would allow for vast scaling potential down the line. Promises for the future include a three nanometer memristor that can switch on and off in a nanosecond, as well as a 20GB per square centimeter memory density that we might expect to arrive within three years. If we believe the dudes in the white coats, that is. The important thing is that memristor-based storage has already been tested to successfully perform "hundreds of thousands" of read and write operations without failing, so the potential is indeed there. Now we just need a bit of luck and a smidgen of patience.
Japanese company to sell Swine Flu-resistant suit -- because nobody wants their clothes to get sick
Japan's been particularly hard hit with this H1N1 influenza marching around the globe, so maybe it shouldn't be surprising that one of its companies has come up with an "anti-flu" suit... but it still is. Japanese clothier Haruyama Trading Company has developed and is now selling a men's suit which will supposedly ward off the H1N1 virus -- not the first time we've seen this idea. The suit, which looks exactly like any other, is coated in titanium dioxide (a popular ingredient found in sunscreen and toothpaste) which reacts when exposed to sunlight and kills the virus. Nobody's really checked into whether or not these things actually work, of course, but hey -- that's part of the fun, right? If you live in Japan, you can grab one for somewhere in the neighborhood of $580. [Via Cnet]
