If you were among the millions of people that watched NBC’s replay of the opening ceremony of the 2018 Winter Olympics in PyeongChang, South Korea on Friday, February 9, you might have seen an airborne snowboarder, a bird flapping its wings, and the iconic Olympic Rings, light up the skies. While they may have appeared to be digital fireworks, the mesmerizing show was the result of thousands of tiny drones preprogrammed to follow complicated flight paths to form the shape-shifting images.
Though pigs may never fly, a two-year-old hog in Franschhoek, South Africa is proving they sure can paint! Meet Pigcasso, the world’s first known pig artist whose masterpieces are selling for thousands of dollars to benefit Farm Sanctuary S.A., Africa’s only registered shelter for rescued farm animals.
Joanne Lefson, who saved Pigcasso from a slaughterhouse two years ago, discovered the animal’s artistic talent accidentally. The South African activist says of the numerous toys presented to keep the then four-week-old piglet entertained, it was the paintbrushes that seemed to attract her the most. They “were the only thing she didn’t eat,” Lefson quips.
Science fiction thrillers frequently feature accidents that cause astronauts to float away into space. Though this has yet to happen in the real world, it is a risk every astronaut is well-aware of when embarking on a spacewalk or Extra Vehicular Activity (EVA). To prevent the nightmare scenario, space explorers are not only tethered to the spacecraft but also fitted with a backup safety kit.
Dubbed Simplified Aid For EVA Rescue (SAFER), the “life jacket,” which is worn like a backpack, contains a bottle of pressurized nitrogen and tiny thrusters. In the unlikely event that an astronaut gets untethered, he/she can use the joy-stick-like controller attached to the front of the spacesuit to return to the spacecraft. The only drawback is that SAFER is manually operated, which means it is of no use if the astronaut becomes unconscious, gets injured, or is simply too panicked to navigate back. The system also requires an extensive amount of ground training.
