Facebook CEO Mark Zuckerberg will tell Congress that embattled libra crypto project will ‘extend America’s financial leadership’ (2 minute read)
Facebook CEO Mark Zuckerberg will testify before the House Financial Services Committee on Wednesday about the Libra cryptocurrency project, which has faced heavy opposition from the government since its announcement. The Libra Association has seen its membership reduced to 21 companies after the departures of Visa, Mastercard, PayPal, eBay, Strip, Booking, and Mercado Pago. Facebook has said it will not launch Libra until it receives regulatory approval. Zuckerberg will argue that Libra will extend America's financial leadership and democratic values around the world. He argues against the idea that Libra is an attempt to replace sovereign currency and that Libra was created only to be an alternative to existing online payment systems.
Powered by Sunlight, ‘Artificial Leaf’ Successfully Produces Clean Gas From CO2 and Water (4 minute read)
Syngas is a gas usually created from fossil fuels that is used to produce a range of commodities, such as fuels, pharmaceuticals, plastics, and fertilizers. Researchers at the University of Cambridge have created an artificial leaf that is able to produce syngas in a sustainable and simple way. The leaf works by using a combination of two light absorbers and a cobalt-based catalyst. It is able to work in low light, even when it is rainy or overcast. The technology may be able to eventually produce a sustainable liquid fuel alternative to petrol.
Japanese hotel chain sorry that hackers may have watched guests through bedside robots (1 minute read)
A hotel chain in Japan uses robots that perform tasks that human employees usually do, for example, check-in guests, showing guests their rooms, and assist with other requirements. The hotels use facial recognition to unlock doors. A few months ago, a security researcher discovered a vulnerability on the robots that allowed easy access to stream video and audio from the robots. The researcher notified the hotel group about the vulnerability but received no reply, so he made the hack public. After the hack was revealed, the hotel group apologized for the vulnerability and patched the software.
