(From phys.org) Facebook-owned WhatsApp’s revelation of a security flaw allowing hackers to inject spyware on smartphones raised fresh concerns about the security of the mobile ecosystem. Here are five key questions and answers: What happened to WhatsApp? The security hole in the WhatsApp messaging app could enable an attacker to inject malware to gain access…
(From phys.org) Quantum computers promise to be a revolutionary technology because their elementary building blocks, qubits, can hold more information than the binary, 0-or-1 bits of classical computers. But to harness this capability, hardware must be developed that can access, measure and manipulate individual quantum states. Researchers at the University of Pennsylvania’s School of Engineering…
(From nytimes.com) For years, Facebook gave some of the world’s largest technology companies more intrusive access to users’ personal data than it has disclosed, effectively exempting those business partners from its usual privacy rules, according to internal records and interviews. The special arrangements are detailed in hundreds of pages of Facebook documents obtained by The…
(From phys.org) Scientists are working to dramatically speed up the development of fusion energy in an effort to deliver power to the electric grid soon enough to help mitigate impacts of climate change. The arrival of a breakthrough technology—high-temperature superconductors, which can be used to build magnets that produce stronger magnetic fields than previously possible—could…
(From phys.org) What happens when a new technology is so precise that it operates on a scale beyond our characterization capabilities? For example, the lasers used at INRS produce ultrashort pulses in the femtosecond range (10-15 s), which is far too short to visualize. Although some measurements are possible, nothing beats a clear image, says…
Three scientists on Tuesday won the Nobel Physics Prize, including the first woman to receive the prestigious award in 55 years, for inventing optical lasers that have paved the way for advanced precision instruments used in corrective eye surgery. Arthur Ashkin of the United States won one half of the nine-million Swedish kronor (about $1.01…
(From phys.org) Scientists at Radboud University discovered a new mechanism for magnetic storage of information in the smallest unit of matter: a single atom. While the proof of principle was demonstrated at very low temperatures, this mechanism shows promise for room temperature operation. In this way, it will be possible to store a thousands of…
(From phys.org) The impact of heavy droughts, heatwaves and cold spells on energy demand and supplies would be lessened with seasonal climate forecasts that allow energy companies to better predict spikes in usage ahead of time, researchers say. Researchers already have the ability to predict what changes in climate can be expected in two to…
The little robotic waiter wheels up to the table, raises its glass lid to reveal a steaming plate of local Shanghai-style crayfish and announces in low, mechanical tones, “Enjoy your meal.” The futuristic restaurant concept is the latest initiative in Chinese e-commerce giant Alibaba’s push to modernise service and retail in a country where robotics…
(phys.org) A team of researchers at the University of California has developed a novel kind of neural network—one that uses light instead of electricity to arrive at results. In their paper published in the journal Science, the group describes their ideas, their working device, its performance, and the types of applications they believe could be…
