Researchers show that different Web programming interfaces can be combined to cloak online activity.
Computer scientists have shown that the functionality many websites expose to developers—to let them build powerful Web applications—can also be combined in potentially nefarious ways.
Physicists have worked out how to build invisibility cloaks that hide objects with the flick of a switch
The first invisibility cloaks appeared about a decade ago. Since then, the theory behind these devices and the technology used to implement them has developed at a breathtaking pace.
If you're a fan of the Mass Effect series then you'll now have to decide whether or not you want to immerse yourself into more of the experience. You see, Electronic Arts has now taken the covers off of Mass Effect Infiltrator and placed it in the Google Play Store. Didn't like the ending of Mass Effect 3? Maybe you can change it:
Electronic Arts has set the price a little high with this one plus, the size of the download may sway some users from grabbing it. Mass Effect Infiltrator is set at $6.99 with the download and additional content coming in at over 450MB once all is said and done. That said though, if you're a fan of the series it might be worth the buy in cost for and SD Card space to you. Download link is below for you all.
Metamaterials that absorb seismic waves rather than steer them, might be a better way to protect some buildings, say engineers
In recent years, cloaking technology has taken the world of physics and engineering by storm. The possibility that any object can be hidden from incident waves has numerous applications, both practical and fantastical.
A nanotube coating would allow a plane to absorb a radar beam, making it undetectable.
A new nanostructured coating could be used to make paints for stealth aircraft that can’t be seen at night and that are undetectable by radar at any time of day. The coating, made of carbon nanotubes, can be used to cloak an object in utter darkness, making it indistinguishable from the night sky.
A cloak that hides magnets from the outside world could have remarkable applications, say physicists
A metamaterial is a bizarre substance with properties that physicists can fine tune as they wish. Tuned in a certain way, a metamaterial can make light perform all kinds of gymnastics, steering it round objects to make them seem invisible.
A flexible metamaterial that manipulates visible light could lead to better camouflage.
Researchers at the University of St. Andrews have created sheets of a flexible metamaterial that can manipulate visible light. “It’s a pretty significant step forward,” says Steven Cummer, professor of electrical and computer engineering at Duke University and the inventor of the first metamaterial-based invisibility cloak. “At radio frequencies we know how to make a lot of these things. But at optical wavelengths, things have been very fabrication-limited.”
