Technology news

	Are your Cyber Monday purchases legit? There's (going to be) an app for that Receiving a bogus designer handbag or imitation Wagyu beef might infuriate a Cyber Monday consumer, but a knock-off respirator or a fake pacemaker could imperil them.
	Internet out: India deploys shutdowns in name of security With the world's largest biometric ID database, a pioneering digital payment system for daily transactions and a flagship space and satellite program, India knows the power of connected technology.
	The flying, swimming and tunneling robots inspired by nature Drawing inspiration from birds, fish and even worms, researchers in Europe are developing machines to explore places on Earth that are difficult for people to reach.
	Researcher: Most of us have no idea what the padlock icon on our internet browser is, and it's putting us at risk Do you know what the padlock symbol in your internet browser's address bar means? If not, you're not alone. New research by my colleagues and I shows that only 5% of UK adults understand the padlock's significance. This is a threat to our online safety.
	Five days of chaos: What just happened at OpenAI? Nearly as quickly as he left, Sam Altman is back.
	Multi-synaptic photonic spiking neural networks based on a DFB-SA chip Compared with traditional artificial neural networks, spiking neural networks (SNN) are more biologically authentic, more powerful, and less power-consuming due to their spatiotemporal coding and event-driven characteristics. In recent years, optical computing has been widely considered as a hardware acceleration platform, where nonlinear computing poses a challenge. Photonic SNN provides an ultra-fast and energy-efficient platform for high-performance neuromorphic computing.
	Renegotiating the relationship between citizens and the development of automated decision-making We are told that artificial intelligence and the automated decisions it enables will offer us improved public governance. Artificial intelligence will flexibly provide consistent and quick decisions, and considerable savings can be achieved thanks to automation.
	Opinion: WeWork approached physical space as if it were virtual, which led to the company's downfall On Nov. 6, the co-working firm WeWork filed for bankruptcy. WeWork, founded by Adam Neumann and Miguel McKelvey in 2010, had a simple business model: it signed long-term leases on urban buildings, fitting them out with modern work facilities. Then, it rented out desks, offices and meeting rooms to companies and freelancers seeking an easy-come, easy-go workplace.
	An environmentally friendly electrochemical refrigerant compressor A research team has successfully developed an environmentally friendly refrigerant compressor using an electrochemical method instead of a mechanical method. The development is published in Renewable Energy.
	Promising salt batteries for heat storage Salt batteries can store summer heat to be used in winter, but which salt works best for the purpose? On 19 December, Lian Blijlevens will defend her Ph.D. thesis on her research into salt for heat storage at Radboud University.
	'Digital winglets' for real-time flight paths born from NASA tech Before airplanes even reach the runway, pilots must file a plan to inform air traffic controllers where they're going and the path they are going to take. When planes are in the air, however, that plan often changes. From turbulence causing passenger discomfort and additional fuel use to unexpected weather patterns blocking the original path, pilots have to think on the fly and inform air traffic controllers of any modifications to their routes.
	Electrofuel developed from green hydrogen and carbon dioxide tested in practice for first time in Finland The E-fuel project of VTT and partners has developed a concept for producing electrofuel from green hydrogen and carbon dioxide using a combination of different methods. On Nov. 21, this paraffinic E-fuel was tested for the first time in Finland on a diesel-powered tractor at AGCO Power's Linnavuori factory in Nokia. The new electrofuel is also suitable for vehicles that are difficult to electrify, and is therefore an important step in the development of sustainable fuel solutions.
	Wave devouring propulsion: A green technology for maritime sustainability A new form of wave devouring propulsion (WDP) could power ships and help to cut greenhouse gas emissions in the maritime industry. Academics from Cranfield University have worked on the concept of using wave energy for propulsion and designed an inventive method of achieving greater thrust from the power of the waves by harnessing a vessel's submerged flapping foils in an innovative way.
	Researchers implement multi-focus image fusion using diffusion models Multi-focus image fusion (MFIF) is an image enhancement technology that helps to solve the depth-of-field problem and capture all-in-focus images. It has broad application prospects that can effectively extend the depth of field of optical lenses.
	Nissan will invest $1.4 billion to make EV versions of its best-selling cars at its UK factory Nissan will invest $1.4 billion to update its factory in northeast England to make electric versions of its two best-selling cars, a boost for the British government as it tries to revive the country's ailing economy.
	Amazon hit by 'Black Friday' strikes in Europe Amazon was hit by strikes at various locations in Britain, Germany and Italy during the annual "Black Friday" shopping extravaganza as workers demand higher wages and better working conditions.
	Machines meet museums: Report unpacks AI in heritage sector Nearly a quarter of U.K. heritage organizations are using artificial intelligence (AI) tools, according to a recent survey commissioned by The National Lottery Heritage Fund (NLHF).
	The challenges hindering the adoption of heat pumps in the UK A new report, led by UofG housing experts, exposes the intricate challenges hindering the adoption of heat pumps in the U.K. Only 55,000 installations are occurring yearly as of mid-2023, considerably behind the U.K. government's annual target of 600,000.
	A biotech slump is emptying labs and threatening research on new drugs Sangamo Therapeutics Inc.'s cost cuts didn't hurt just the roughly 162 U.S. workers who lost their jobs this month. It's also a blow to Jerry Walter, who's lost five family members and suffered kidney, lung, hearing and heart damage from a rare disease.
	Good AI, bad AI: Decoding responsible artificial intelligence Artificial intelligence (AI) is so hot right now. ChatGPT, DALL-E, and other AI-driven platforms are providing us with completely new ways of working. Generative AI is writing everything from cover letters to campaign strategies and creating impressive images from scratch.
