Facebook patent talk: Seeing who is rich, poor, in the middle
"Socioeconomic group classification based on user features," is a title that evokes an uh-oh just as much as an oh-really. Face It, there is sensitivity regarding actions designed to help marketers know the right targets for the right message that nonetheless may be interpreted as intrusive. Well, that is a patent title. Facebook filed the patent in July 2016 and it was made public just recently. Facebook is interested in a system that can work out which socioeconomic tier defines you.....
Researchers reveal new details on aged brain, Alzheimer's and dementia

Transparent solar technology represents 'wave of the future'
See-through solar materials that can be applied to windows represent a massive source of untapped energy and could harvest as much power as bigger, bulkier rooftop solar units, scientists report today in Nature Energy. Led by engineering researchers at Michigan State University, the authors argue that widespread use of such highly transparent solar applications, together with the rooftop units, could nearly meet U.S. electricity demand and drastically reduce the use of fossil fuels. "Highly transparent solar cells represent the wave of the future for new solar applications," said Richard Lunt, the Johansen Crosby Endowed Associate Professor of Chemical Engineering and Materials Science at MSU. "We analyzed their potential and show that by harvesting only invisible light, these devices can provide a similar electricity-generation potential as rooftop solar while providing additional functionality to enhance the efficiency of buildings, automobiles and mobile electronics."....

Nanodiamonds show promise for aiding recovery from root canal
People who undergo root canals may soon have a tiny but powerful ally that could prevent infection after treatment. Researchers at the UCLA School of Dentistry and the UCLA Henry Samueli School of Engineering and Applied Science found in a clinical trial that nanodiamonds protected disinfected root canals after the nerve and pulp were removed, thereby improving the likelihood of a full recovery. The findings are a milestone for the use of nanodiamonds in humans. Nanodiamonds are tiny particles made of carbon and are so small that millions of them could fit on the head of a pin. They resemble soccer balls but have facets like actual diamonds. Those facets enable the nanodiamonds to deliver a wide range of drugs and imaging agents. In a paper published Oct. 23 in Proceedings of the National Academy of Sciences, the UCLA researchers write that combining nanodiamonds with gutta percha, a material used to fill disinfected root canals, may enhance the gutta percha's protective properties.....
Scientists update four key fundamental constants
Paving the way for transforming the world's measurement system, an international task force has determined updated values for four fundamental constants of nature. The updated values comprise the last scientific piece of the puzzle for redefining the modern metric system, known as the International System of Units (SI). If approved by an international body next year, the revised SI will enable authoritative measurements to be made anywhere on the planet....

Patent Pick: Starch Breakdown Builds Viscosity
Thickening agents are nothing new. They've long been used to control the viscosity of cosmetic, dermatological and pharmaceutical compositions, paints, phytosanitary products and detergents, among others. Yet, while many thickeners are well-known, according a new Novamont patent application, the majority are of synthetic origin and generally carry with them a higher production cost and unfavorable (unsustainable) origin. The industry has responded by replacing these thickeners with others of renewable and natural origin. However, their performance is not fully comparable to their counterparts, and production costs are still not competitive.....
China streamlines patent examination for Internet, big data patent applications
On July 28th, 2017, China’s State Intellectual Property Office (SIPO) announced a new set of regulations which are intended to streamline the examination of patent applications in certain burgeoning fields of technology. The new policy, which comes in response to “the central government’s call for an improved business environment, streamlined procedures for administrative approval, and the booming market,” will allow for the examination of both utility model and industrial design patent applications; SIPO guidelines issued as recently as five years ago only covered a single patent application designation, invention patents....
Patent Pick: How Low Can pH Go?
According to a new P&G patent application, cosmetic compositions typically are formulated with a slightly acidic to neutral pH, from 4.0–7.0. This improves the stability of ingredients such as niacinamide, salicylates and neutralized thickeners. However, a lower pH, e.g., 1.0–4.0, may bolster the acid mantle of the skin. This, in turn, could provide flexibility for the addition of other skin agents and/or provide exfoliating benefits—drastically changing the landscape of current cosmetics and personal care formulations. This concept was previously described by Wiechers. In consideration, P&G inventors aimed to develop a low-pH skin care composition that incorporates niacinamide and a suitable saccharide in order to improve skin's barrier function and appearance....

Takeoff and cruise: Toyota making 'flying car,' luxury boat (Update)
Toyota Motor Corp. is working on a "flying car."
A startup backed by the Japanese automaker has developed a test model that engineers hope will eventually develop into a tiny car with a driver who'll be able to light the Olympic torch in the 2020 Tokyo games. For now, however, the project is a concoction of aluminum framing and eight propellers that barely gets off the ground and crashes after several seconds. Toyota has invested 42.5 million yen ($386,000) in startup Cartivator Resource Management to work on "Sky Drive ." At a test flight Saturday in the city where the automaker is based, the gadgetry, about the size of a car and loaded with batteries and sensors, blew up a lot of sand and made a lot of noise....
