The American Red Cross is now checking all blood donations for coronavirus antibodies, instead of just searching for recovered patients. The organization is calling it a “game changer.”“We can then not only inform that donor of the testing results that we've identified COVID-19 antibodies in their blood, but also use that product as convalescent plasma to help patients who are ill with COVID-19 in the hospital,” said Dr. Pampee Young, Chief Medical Officer at the American Red Cross.Early results from the National Institutes for Health show the plasma can make a big difference for severely sick COVID-19 patients. And data from these new tests will help those researchers working to better understand the virus.The Red Cross says the need for whole blood donors is constant, but plasma is more unpredictable.Over the summer, plasma supplies ran low after unprecedented infections and demand in some states.Now, they're asking more donors to step up to restock for another potential surge in the fall and winter.“Because we can’t predict the demand, we want to ensure that we have enough inventory, because what really saves lives are the units that are on the shelf, not something that we need to collect once we realize there’s a need,” said Young.The Red Cross has taken additional safety steps during the pandemic. That includes making an appointment.You can sign up online at RedCrossBlood.org or by using the blood donor app. 1444

The auction house says it didn't know anything about it. The artist famously doesn't like to show his face. The buyer is a mystery. So, for that matter, is the seller.In the case of the "self-destructing Banksy", nothing adds up.The startling stunt at Sotheby's in London has set the art world aflame. The image of a girl reaching out for a red, heart-shaped balloon had just sold, for .4 million.Moments later, a shredder hidden inside the picture frame began to whirr, the canvas slid down, and at least part of it ended up in strips.Sotheby's claimed it had been "Banksy'd."The British street artist, famous for being faceless, is certainly well known for his stunts. In 2006 he secretly erected a life-size replica of a hooded Guantanamo Bay detainee inside a ride in the California Disneyland theme park. In 2013 he set up a stall selling his original artwork for in a New York market and filmed people passing by, convinced that because of the price, the works were fake.On Saturday, Banksy published a video on Instagram that purported to show how he built a paper shredder into the frame of the 2006 painting "Girl with a Balloon.""The urge to destroy is also a creative urge," Banksy wrote, citing Picasso.But the video didn't answer everyone's questions -- not least about the involvement of the auction house. 1334

Tesla on Thursday recalled about 123,000 Model S sedans, asking customers with cars built before April of 2016 to have their power steering bolts replaced.A Tesla spokesperson said the company has observed "excessive corrosion" of the part in some cold climates where a certain type of road salt is used.No injuries or accidents have been reported in connection with the issue, the spokesperson said.A Tesla spokesperson said that if the bolts fail, the driver should still be able to control the vehicle. The issue can make the car more difficult to steer at low speeds and to parallel park, and it should "not materially affect control at high speed."The company sent out emails to Model S owners who have cars included in the recall.The Model S has been lauded for its safety ratings, but news of this recall comes at a rough time for Tesla.Its stock price has plunged more than 25% over the past month. Investors are worried about the startup's ability to deliver on its first mass-market car, the Model 3, which has been plagued by manufacturing woes.Tesla's stock sank nearly 4% during after-hours trading Thursday after news broke about the Model S recall. 1171
