MIT researchers and their colleagues are designing an imaging system that can read closed books. In the latest issue of Nature Communications, the researchers describe a prototype of the system, which they tested on a stack of papers, each with one letter printed on it. The system was able to correctly identify the letters on the top nine sheets.
The National Institute of Standards and Technology and the US Naval Observatory, which operate US civilian and military time standards, respectively, have worked with two companies -- Monroe, Louisiana-based CenturyLink, and Aliso Viejo, California-based Microsemi -- to identify a practical GPS backup possibility: commercial fiber-optic telecommunications networks.
An international group of biologists is calling for data collection on a global scale to improve forecasts of how climate change affects animals and plants.
An algorithm developed at Carnegie Mellon University makes it easier to determine if someone has faked an Amazon or Yelp review or if a politician with a suspiciously large number of Twitter followers might have bought and paid for that popularity.
Random number generators are crucial to the encryption that protects our privacy and security when engaging in digital transactions such as buying products online or withdrawing cash from an ATM. For the first time, engineers have developed a fast random number generator based on a quantum mechanical process that could deliver the world's most secure encryption keys in a package tiny enough to use in a mobile device.
Sharks and minnows: Scientists discover an optical soliton wave that rides with and feeds off of other soliton waves, much like a pilot fish with a shark.
Scientists at the Energy Department's National Renewable Energy Laboratory (NREL) discovered a use for perovskites that runs counter to the intended usage of the hybrid organic-inorganic material.
The Energy Department's National Renewable Energy Laboratory (NREL) has released the 2016 Annual Technology Baseline. In addition to updated data for utility-scale renewable and conventional energy technologies, this year's version includes cost and performance data for residential and commercial rooftop photovoltaics (PV) systems.
Retailers and advertisers are keen to influence the search and final purchase through better product recommendations and targeted advertising. A forthcoming article in the INFORMS journal Marketing Science studies online search and purchase behavior of consumers in the digital camera category and finds that even though consumers may search for extended periods of time, what they purchase tends to be remarkably close to items they searched and found in their very first search.
ETH researcher Stefan Pfenninger and his colleague Iain Staffell from Imperial College London have developed new multi-decade simulations of wind power production in Europe. In doing so, they have uncovered significant distortions in the data used in the past, and have produced fresh simulations of wind power output with country-specific corrections.
