The technology behind the Russian vaccine is based on adenovirus, the common cold. Created artificially, the vaccine proteins replicate those of Covid-19, triggering an immune response similar to that caused by the coronavirus itself ie immunization is similar to having survived the virus, but without its life-threatening risks.The research has been funded by Russia’s sovereign wealth fund and the vaccine discovery process has been compared to the Space Racehttps://www.rt.com/russia/497360-russia-first-covid19-vaccine/
Researchers at Nanyang Technological University in Singapore have developed a prototype, called the Anti-Noise Control Window, that expands the concept of noise-cancelling headphones to encompass an entire room. The prototypes consist of 24 small speakers that are placed in a window and emit sound waves that correspond to incoming noise and cancel it out.
