Facebook Plans Global Financial System Based on Cryptocurrency (7 minute read)

Facebook has revealed plans to build an alternative financial system based on a cryptocurrency. Libra was announced with 27 partners, including Mastercard and Uber. Facebook aims to launch the cryptocurrency with 100 partners next year. The company hopes that Libra will become the foundation for a financial system that is not controlled by banks. Libra will be backed by government currencies, so it will not fluctuate more than real-world money, unlike Bitcoin. The project will be run by a non-profit entity in Switzerland, independent of Facebook, as Facebook is distancing itself from direct management of Libra. This is in order to protect the privacy of people who use the currency. Facebook promises that users’ financial data will never be used to target ads on its platform.

Mysterious Clouds on Mars Formed by ‘Meteoric Smoke,’ Study Says (2 minute read)

A new type of cloud has been discovered on Mars that is created from debris that burns up in the planet’s atmosphere. This ‘meteoric smoke’ stimulates cloud formation at altitudes between 30 and 60 kilometers. The clouds form best during cold weather when ice vapor can build around the interplanetary dust particles in the middle atmosphere. A similar process can also happen in Earth’s skies when meteoric dust falls into our atmosphere. Three to four tons of alien dust enters Mars’ atmosphere every sol, but only a fraction ever reaches lower altitudes. This process may explain cloud formation during Mars’ early years, and a similar process may be happening on any number of other planets outside our solar system as well.

Scientists use sound to see around corners (1 minute read)

Researchers in Long Beach, California have developed a device - a vertical pole fitted with standard microphones and small car speakers - that uses sound to see around corners. The microphones pick up echoes resulting from a series of chirps emitted by the speakers, and after collecting echoes from different positions, the scientists used algorithms from seismic imaging to reconstruct objects that were not visible from the device’s position. Using this method was faster and more accurate than current optical techniques. While the results are promising, the technique is still years from being able to be practically applied.

Boeing employee: I would not put my family on a Max plane right now (3 minute read)

A Boeing employee has spoken on a radio show about the state of the company on the promise of anonymity. The employee primarily worked on the 777X model. However, when commenting on the 737 Max, which is currently embroiled in controversy, the employee stated that he wouldn’t risk letting his family on one of the aircraft. The company is currently experiencing low morale, as management has been unclear on the direction of the company with employees, and there are rumors of upcoming layoffs. Boeing claims that companies which purchase airplanes were responsible for training pilots correctly. As the training isn’t mandatory, some pilots are unaware of essential systems, such as the MCAS system that failed in two airplanes, causing crashes. While the employee trusts his colleagues and the work they do, he is unsure about the management, and still has reservations about the 737 Max planes.

YouTuber Simone Giertz transformed a Tesla Model 3 into a pickup truck (3 minute read)

Tired of waiting for Tesla to release its new Tesla pickup truck, YouTuber Simone Giertz decided to make her own by transforming her Model 3. After a year of planning and designing, a team of mechanics and DIY car modifiers helped Giertz to build the truck, all while being filmed. Elon Musk has been hyping up the Tesla pickup truck for several years, promising that it won’t look anything like other trucks on the market. Giertz says she performed the stunt to celebrate Musk’s products, as a Tesla pickup truck would truly be her dream car. The final video, pictures of the finished truck, and a link to a fake truck commercial produced by Giertz are available.
