New Invisibility Cloak is Extremely Thin
All-rounder Minimalist Cape
The new best thing to protect us from the elements is this radical innovation called The Mavari, a reversible contemporary cloak crafted with a unique triple layer fabric. The purpose is, of course to protect us from the unpredictability of Mother Nature.
We asked the designers, what made the Mavari so special and this is what they said, “The reversible cloak is waterproof, windproof, absorbent, breathable and features antibacterial properties that allow you to dry after a swim. You can even change in-and-out of a wetsuit! It also provides shelter from the cold and light rain and helps us stay dry all day.” In short, it is an all-weather friend and a MUST HAVE for both men and women!

Cloak App Helps Avoid Social Interaction
While most applications involving social media encourage interaction, Cloak is an anti-social app developed to help individuals avoid interaction.
Cloak is a mobile app for iOS (iPad, iPhone, iPod touch) that will query posts on Foursquare and Instagram for individuals that you specify, or for everyone in your social network, and try to identify their last known location. Individuals that were recently nearby will show up on a map identifying where they recently were so you can go somewhere else. After about four hours the locations time off and no longer show, assuming the individual you want to avoid has moved on.
The app currently only interacts with Foursquare and Instagram, so your anti-target must utilize one of these services for the system to work but the creators hope to integrate with other social media services soon including Facebook, Twitter, Google+, Snapchat and Tinder.
“We feel like we’ve reached the point of social fatigue — too many networks with too much information, all the time,” says Chris Baker, one of the co-creators of the Cloak app. “It’s OK to turn off and pick up a copy of ‘Walden’ and just be alone.”
Seismic Cloak Could Protect Your House, But Your Neighbors Won’t Be Happy
When someone starts talking about cloaking devices and technology, I immediately reference the Romulan tech of Star Trek. However, when it comes to earthquakes, scientists are working on a way to cloak entire structures from tremors.
The so-called “seismic cloak” would help protect buildings, power stations and dams from earthquakes, by using metamaterials to divert the seismic waves around an area. Seismic waves have a longer wavelength than light, making them a lot easier to push around. Recently, researchers in France performed the first large-scale test of seismic cloaking.
They came up with an array of empty holes that were able to redirect seismic waves so well that acoustic sensors beyond the second row were hardly able to detect the waves. Now, scientists have to address how to deal with real quakes that come in a number of different wavelengths, and figure out what to do with the redirected seismic energy, otherwise adjacent structures could end up bearing more than their fair share of the quake’s energy.

Duke University creates ‘perfect’ one-directional microwave cloak, might lead to stealthier vehicles
Most attempts at cloaking, no matter the slice of spectrum, usually leave clues as to what's there -- even microwave cloaks can spoil the surprise through reflections. At Duke University, researchers have licked some of those past problems with the first instance of a flawless microwave cloaking scheme. By crafting a special diamond-shaped cloak where the light properties stay consistent at the corners, the school's Nathan Landy and David Smith have successfully shielded a 3-inch wide cylinder from microwave detection without a hint that something was amiss. The gotcha, as hinted by the shape, is a two-dimensional nature that gives away the secret at less than ideal angles. Duke suggests that it still has the groundwork for something that could be vital for communications or radar -- we can imagine a stealth aircraft or ship in the far-flung future that could actively mask itself from radar signals. It's not quite the optical illusion we're looking for, but a refined version of the Duke project might be enough for a rare practical use of cloaking when fantasies are much more common.

It’s true that surfing the web through public connections isn’t that safe. I still remember a crazy computer virus I got in Thailand that migrated from my compact flash card onto my home system. Cloak aims to improve network security by sending traffic through a VPN that encrypts all of your Internet traffic.
Cloak is easy to set up and currently only works for iOS devices and OSX computers. Android and Windows versions are coming along though. This app is to be used in unsecured networks, like at the airport, coffee shops, and while you’re traveling. It looks like something that’s worth using if you use public connections a lot.
Cloakis free for the first 2 hours per month or 1 GB, but after that you’ll need to sign up for a premium account, which cost between $8 and $15 per month depending on your data needs.
