NASA says it has succeeded in deflecting an asteroid in a historic test of humanity's ability to stop an incoming cosmic object from devastating life on Earth. The fridge-sized Double Asteroid Redirection Test (DART) impactor deliberately smashed into the moonlet asteroid Dimorphos on September 26, pushing it into a smaller, faster orbit around its big brother Didymos, says NASA chief Bill Nelson in a press conference from Washington.

E-readers like Kindles only use power when the content of the screen changes. Because of that, Kindles have a long battery life. That means you probably need to charge it every few days or weeks rather than once a day. Still, Business Insider reports there are a number of ways to save the battery life on your Kindle--especially if it's aging and the battery is wearing out. Keep your reading light as low as possible, and put your Kindle to sleep when you're not using it. Next, don't have it connected to the internet when you don't need it. Switch it to airplane mode in the Settings menu. Finally, when downloading books, charge both during the download and a little bit after, while the Kindle updates. That will save lots of juice!
Pulse oximeters measure the percentage of oxygen in the blood when clipped onto a fingertip. And according to HuffPost, they're becoming increasingly popular for home use. People are buying them to monitor a family member if he or she becomes seriously ill with COVID-19. Doctors praise the use of pulse oximeters because they can alert people who don’t realize they’re gravely ill to the fact that their body is struggling for oxygen. One of the biggest worries with COVID-19 is when someone doesn’t realize their oxygen levels have dropped because they don’t actually feel unwell. It's a phenomenon sometimes referred to as happy hypoxia or silent hypoxia. As a normal reading usually ranges from 95-100%, if your reading is under 95%, it's a red flag. Seek medical attention immediately.
