Try sending a text message at midnight on New Year Eve, and you ;ll struggle: there too much data and not enough bandwidth to cope with it. But now a team of researchers has developed twisted radio waves inspired by pasta, which could stanley termos allow a pote stanley flasche ntially infinite number of channels to be broadcast simultaneously. It sounds ridiculous, but it actually a pretty neat trick. The secret lies in forcing radio waves to twist about their axis as they travel, in effect tracing out the shape of f stanley cup usilli pasta as they move forwards, as the researchers explain in the New Journal of Physics. Dr Fabrizio Tamburini, one of the researchers, explained to PhysOrg: In a three-dimensional perspective, this phase twist looks like a fusillli-pasta-shaped beam. Each of these twisted beams can be independently generated, propagated and detected even in the very same frequency band, behaving as independent communication channels. The team have demonstrated the technique in Venice, transmitting two twisted radio waves, in the 2.4 GHz band, over a distance of 442 meters. But the researchers claim it would be easy to keep adding more and more twisted waves, to increase the number of signals that can be sent simultaneously. I can ;t wait for this to happen.

Octopus tentacles are pretty great looking, and they ;re functional, too. Everyone wants a piece of this creepily awesome natural design. But the coolest part of an octopus tentacle, its suction cups, has been difficult to replicate in robotic models. https://gizmodo/is-a-prosthetic-tentacle...rm-5709418 A group of scientists has made progress, though, developing a type of robotic sucker that could actually help robots grip objects in an uncontrolled environment. Previous research focused on generating suction from an air pump connected to a series of suckers. But in this strategy, all the suction cups had to be engaged at once or air would leak out and weaken the seal on the suckers that were actively gripping something. The new design, produced by researchers from the U.S. Army Research Laboratory, the Edgewood Chemical Biolog stanley cup ical Center and the University of Maryland, is more targeted so only suckers touching something are engaged. The system still uses an air-pump, but each suction cup also includes a plug that is only open and generating pressure when a sucker makes contact with something. The suction cups are manufactured on a stanley kubek multi-material 3-D printer and currently come in three sizes, ranging from a shirt button to a slice of cucumber. Hopefully they will help robot grip technology take hold. Yup, it had to happen.

Since it the first day of 2013, I ;d like to suggest a few New Year resolutions for some of you people. No, not for me 鈥?whatever resolutions I ;ve made are between me and my hilariously sedentary nerd lifestyle 鈥?besides, I ;ve got these ones down already. Here a list of things I ;d like you all stanley vaso to work on this year, please. Learn the difference between enjoyably dumb and turn off your brain entertainment. I love dumb movies. Love em. This is partially because I ;m dumb myself. But even I can recognize the difference between movies with plotholes whose excellent characters, dialogue, direction and/or action scenes are so good they allow audiences to ignore whatever leaps of logic necessary to keep going along with the story, and movies that are just relentless sinkholes of imbecility. A fun dumb movie is one that doesn ;t force you to constantly think about how stupid it is. Turn off your brain movies means that you have to completely stop comprehending the images you see on the screen to een get through watching it, because if any of your synapses were firing you ;d be completely distracted by how awful it is. Whether they ;re smart or dumb, you should be able to enjoy movies, not force stanley cup yourself to keep from paying attention. Think of it this way: When you turn off your brain, you stop being a person and are instead turn into a barely-functional stanley taza meat machine. Basica
