šA potential model for a real physical warp drive: A group of independent physicists at Applied Physics may have found a path to implementing warp drives without traversing the laws of physics. For decades many physicists scoffed at the idea of Warp Drives until it became clearer that they merely implied the folding or bending of space instead of the object being warped having an implied speed greater than that of light.

š¤OpenAIās state-of-the-art machine vision AI is fooled by handwritten notes: AI has dramatically advanced since the conception of the field. That said, it isnāt perfectā¦ far from it actually. Thereāve been several examples of researchers making use of blind spots in model architecture to exploit them. Sometimes these blindspots reveal themselves in several hilarious ways like in this one. OpenAIās CLIP vision learning system will basically call a pen a dog if you just happen to place a piece of paper on the pen with the word ādogā written on it. As hilarious as it is, weāve come a long way from merely playing around with tensors toā¦ wellā¦ systems that can read and describe objects based on what they see. This funny instance in many ways is also very much a celebration of how far weāve come. (681 words)
šSelf-flying drones are helping speed deliveries of COVID-19 vaccines in Ghana: Very often breakthrough technologies rarely show their efficacy in places their original creators them to. Instead, they reveal their potential in nations still ascendant. The case of vaccination and the use of drones for delivery in Ghana is one such example. It is making use of a company called Zipline to deliver vaccines to areas that are difficult to reach. (640 words)
ā'Wearable microgrid' uses the human body to sustainably power small gadgets: A group of Nanoengineers from the University of California San Diego, have created a wearable microgrid that generates and stores power from the body. The grid makes use of triboelectric generators which generate energy from motion, bio-fuel cells which generate energy from sweat, and supercapacitors to store all of this energy. The grid can then be embedded in clothes and other wearables for use. (902 words)
