Earth’s magnetic north pole is hurtling toward Russia

Posted by in category: mobile phones

(CNN) — The north magnetic pole has been drifting so fast that it could be a problem for smartphone maps and navigation systems.

The pole has been the friend of navigators for millennia, beckoning compass needles from virtually every point on the planet. And unlike the geographic north pole, which is fixed, the north magnetic pole has been slowly migrating over time — moving across the Canadian Arctic toward Russia since 1831.

But its swift pace toward Siberia in recent years at a rate of around 34 miles per year has forced scientists to update the World Magnetic Model — used by civilian navigation systems, the North Atlantic Treaty Organization, and US and British militaries — a year ahead of schedule.

China Built an AI to Detect Corruption and Officials Shut it Down

Posted by in categories: information science, mobile phones, robotics/AI

AI may quickly point out a corrupt official, but it is not very good at explaining the process it has gone through to reach such a conclusion.

“We just use the machine’s result as reference,” Zhang Yi, an official in a province that’s still using the software, told the SCMP. “We need to check and verify its validity. The machine cannot pick up the phone and call the person with a problem. The final decision is always made by humans.”

New Metamaterial Transmits Light With No Energy Loss

Posted by in categories: computing, mobile phones, space

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.

Design and Clinical Evaluation of the Interoperable Artificial Pancreas System (iAPS) Smartphone App: Interoperable Components with Modular Design for Progressive Artificial Pancreas Research and Development

Posted by in categories: biotech/medical, information science, mobile phones

#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.

Meet The Kenyan Engineer Who Created Gloves That Turn Sign Language Into Audible Speech

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.
