Very soon we might be able to say good riddance to the overheating laptops, phones and tablets that we deal with every day. Electrons carry information around circuits but lose energy as heat during transmission. Electrons are the best thing we have right now for computing, but in the near future we could wave goodbye to electronics and welcome photon, or light, communication that will be both faster and cooler. There are still few hurdles before we can get this technology in every home and every pocket, but one of its limitations was just solved by the development of a new metamaterial.

A metamaterial is a substance that has properties not observed in nature. In this case, the special property is its refractive index, a value that describes how light propagates through a medium. Take water or glass, for example, which cause light rays to bend as they travel through them. This is why pools always look shallower than they actually are.

The new metamaterial has a refractive index of zero, which means that the light phase in the material can travel infinitely fast. This doesn’t mean that relativity is violated by this material, though. Light has a “group velocity,” the velocity at which the wave propagates into space, and a “phase velocity,” the velocity at which the peaks of the waves move with respect to the wave.

Where we’re going, we don’t need batteries.

Using the new device is almost like harvesting electricity out of thin air.

#OpenAccess #FullArticle The results of a new clinical trial have shown the safety and efficacy of the interoperable Artificial Pancreas System smartphone app (iAPS), which can interface wirelessly with leading continuous glucose monitors (CGM), insulin pump devices, and decision-making algorithms. The clinical trial and the app, which runs on an unlocked smartphone, are described in an article published in Diabetes Technology & Therapeutics (DTT), a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

Twenty-five-year-old Kenyan engineer and innovator, Roy Allela, has created a set of gloves that will ultimately allow better communication between those who are deaf and those who are hearing yet may not necessarily know sign language. The Sign-IO gloves in essence translate signed hand movements into audible speech.

Allela’s gloves feature sensors located on each finger that detect the positioning of each finger, including how much each finger will bend into a given position. The glove connects via Bluetooth to an Android phone which then will leverage use the text-to-speech function to provide translated speech to the hand gestures of a person signing.

Scientists made a ‘new’ periodic table of elements to show how smartphones (and party balloons) are draining Earth’s resources.

Does your phone’s short battery life bug you? Static electricity could be coming to the rescue.

The piezoelectric materials that inhabit everything from our cell phones to musical greeting cards may be getting an upgrade thanks to work discussed in the journal Nature Materials released online Jan 21.

As the smartphone market matures, startups are racing to predict what’s next, and venture-capital firms are spraying money into fields like virtual reality, smart watches and even implants in the brain. Here are some of the startups attracting investment.

Venture-capital investors are spraying money into fields like virtual reality, driverless cars and even implants in the brain.

This is a horrible, horrible idea. The company wants to create a series of satellites that can unfurl, which will reflect light, and that can be manipulated to send messages to earth. The entire collection, comprised of CubeSats, will provide an area of about 50 sq. km. and create a whole new kind of orbital debris.

According to the website, “When phones don’t work, during zero visibility, power cuts and catastrophical emergencies – government can use the display for urgent notifications for the population.” We can ignore the idea of them being seen during zero visibility, but can you imagine a message floating in the sky that you can’t just turn off?

It was bound to happen.
