The Wake Forest Institute for Regenerative Medicine says it has a new use for its bioprinting system. In the past they've 3D printed normal-size organs and tissues in hopes of someday implanting them in patients.For the coronavirus, the lab is creating organs using human cells that can be as small as a pinhead. They're focusing on the organs most likely to be infected by the disease. like the lungs.“And so we've been playing with a number of agents to, on both prongs what can make it more infective, what can make it less infective to try to sort this out for the future,” Anthony Atala, director for the institute said.Atala says he hopes the system will help in testing drugs before they hit the market.Drug companies do extensive testing and clinical trials in people before releasing a new medication.Atala says sometimes those companies find no serious side effects, but then years later, discover that it's toxic to patients taking it. Atala says testing a drug using the bioprinting system can tell if a drug is toxic in weeks instead of after years on the market.“Even though we've used the tool extensively for toxicity testing, it's also a tool that can be used for screening,” Atala said. “So we can test agents that are currently being considered for testing against COVID and test the efficacy of the treatment on miniature human organs made up of normal cells”To be clear, Atala said drug tests on 3D printer organs are not meant to replace clinical trials in humans, be are an added step to better predict what will happen in those trials. 1567

The UK will expel 23 Russian diplomats from the country after concluding that the Russian state is responsible for the attempted murder of former Russian spy Sergei Skripal and his daughter Yulia in the English city of Salisbury.This will be the single biggest expulsion of Russian diplomats in over 30 years, Prime Minister Theresa May said Wednesday. The 23 concerned, who May said had been identified as undeclared intelligence agents, will have only one week to leave."For those who seek to do us harm, my message is simple. You are not welcome here," she said in a statement to the House of Commons following a meeting of Britain's National Security Council.The expulsion of diplomats will "fundamentally degrade" Russian intelligence capabilities in Britain for years, May said.The Skripals are critically ill in hospital after being exposed to the nerve agent, known as Novichok and developed in Russia, on March 4. Thirty-eight other people in Salisbury were seen by medics after the exposure. One, a police officer, remains hospitalized.May said Monday it was highly likely that Moscow was behind the poisoning. The Russian ambassador to the UK was summoned to the UK Foreign Office to explain whether the attack was directed by Russian authorities, or whether Moscow had lost control of the nerve agent.She demanded that Moscow respond by midnight Tuesday, London time, to the UK government's conclusion that Russia was linked to the poisoning of Sergei Skripal and his daughter Yulia on a park bench in Salisbury in southern England.But Moscow -- which has repeatedly dismissed any accusations of involvement in the attack -- ignored the deadline.  1672

The U.S. Geological Survey recorded two earthquakes in Tennessee early Wednesday.The first happened at about 3:15a.m. and was reported to be a magnitude 4.4. The second was recorded at about 3:30a.m. and was a magnitude 3.3.According to the USGS Intensity map, as of 3:45a.m., more than 2000 people reported feeling the earthquakes across Tennessee, North Carolina, Alabama, and Georgia.Some people reported feeling weak shaking in areas of Middle Tennessee, like Hendersonville, Cookeville, and Murfreesboro. According to the National Weather Service office in Morristown, the largest earthquake on record in East Tennessee was a magnitude 4.7 near Marysville in 1973. The USGS?studied the reason why earthquakes are felt at much farther distances on the east coast, compared with earthquakes that hit the west coast. Researchers found that some factors have to do with tectonic plates and their geological history. The east coast has older rocks, which researchers said allow seismic waves "to cross them more effectively during an earthquake." 1084

The Smithsonian announced the reopening of two prominent Washington, D.C., area attractions that have been shuttered during the spread of the coronavirus.The National Zoo located in Washington and the National Air and Space Museum in nearby Chantilly, Virginia, are scheduled to reopen Friday with a number of safety precautions in place. All other Smithsonian attractions will remain closed. Most other prominent D.C. destinations, including the White House and Capitol, also remain closed to visitors.Both at the zoo and the National Air and Space Museum, all visitors age 6 and over will be required to wear face coverings. The zoo and museum are also requiring timed tickets, and has scaled back its hours to close at 4 p.m.“As a public entity, we thrive on serving our visitors and making our collections readily available to them, virtually and in person,” said Lonnie Bunch, Secretary of the Smithsonian. “However, the safety and well-being of our staff, visitors and volunteers come first and are paramount, so we are taking a deliberate, phased and cautious approach to reopening. Our goal is to be safe and measured in order to adjust and pivot as necessary.” 1177

The University of Utah nurse at the center of a highly controversial arrest that was recorded on the officers' body cameras has reached a 0,000 settlement with all parties involved.In addition, Alex Wubbels announced Tuesday afternoon that she will use part of that money to launch a new initiative to make body camera video more accessible to all residents in Utah involved in a police incident."I am not in the business of setting anyone up for failure. I want us to be successful in moving forward. And I think this is a small step we can provide to enable that potential success if we are going to start asking the police departments to have body cameras,” Wubbels said outside the Salt Lake City Police Department while standing next to her attorney, Karra Porter.The nurse added "it's shocking" that today's police forces don’t all have body cameras."We all deserve to know the truth. And the truth comes when you see the actual raw footage. And that’s what happened in my case. No matter how truthful I was in telling my story, it was nothing compared to what people saw and the visceral reaction people experienced when watching the footage," she said.Wubbels' widely publicized arrest happened July 26 when Salt Lake detective Jeff Payne was sent to University Hospital to collect blood from a man injured in a crash that killed the driver who caused it. Wubbels — citing policy agreed upon by the hospital and the police department — declined to tell Payne where the patient was or allow him to draw blood.The detective, with direction from his supervisor that day, Lt. James Tracy, ultimately arrested the screaming nurse after physically pushing her out of the emergency room and holding her against a wall while handcuffing her. Police body camera video of the incident caused outcries of protest from across the country and prompted Salt Lake City Mayor Jackie Biskupski and Salt Lake Police Chief Mike Brown to personally apologize to Wubbels for the way she was treated while doing her job.Payne was fired from the police department. Tracy was demoted to the rank of officer. Both men have since appealed their discipline. Their appeals remained pending as of Tuesday.Wubbels and Porter — who never filed a civil lawsuit — announced she had reached a settlement with all "U.-related and Salt Lake City-related parties" who would have potentially been named if a lawsuit had been filed."There will be no legal lawsuit. This part of this is over. We’re hopping the discussion about body cameras continues,” Porter said.Matthew Rojas, spokesman for Salt Lake Mayor Jackie Biskupski, said both the city and the university agreed to pay 0,000 each."Salt Lake City has been focused first and foremost on ensuring policies and procedures are changed so things like this don’t happen again, and we are glad we could come to a resolution with nurse Wubbles," he said.Since Wubbels went public with the arrest video, Porter said her client has had several goals, including changes to policy on how police interact with nurses; accountability by the officers involved; starting a public discussion on the importance of body camera video; compensation; and helping others.Wubbels is working with the American Nurses Association on a campaign to prevent what happened to her from happening elsewhere. She also would like to speak before the Utah Legislature during the next session about the importance of making body cameras mandatory for all police agencies. And she and Porter want to help all Utahns have access to body camera video for their own cases."Thanks to Alex, there will be more transparency as body cam footage becomes more readily available in Utah,” Porter said.Wubbels said she was grateful for how Salt Lake City has responded to her arrest and the settlement, but also noted she still becomes emotional when thinking about the incident."This landed in my lap. This is not something I sought out. I didn’t seek out the last four months," she said. "I’m incredibly humbled by change that’s happened."This is very emotional," Wubbels continued, "This is an emotional situation. … I’m still processing this. I mean, this is something I never expected to happen. But I’m also honored by the weight of it and honored to be the one to help make progress in our society at large."Porter said body cameras are also important for protecting officers, with both Wubbels and Porter emphasizing there are many good officers. They stressed that fact when talking about the fatal shooting and manhunt at the university that forced the campus to go into lockdown Monday night."I literally park where this incident happened. I walk, in the dark, every night to my work, back and forth to my car where this incident happened,” Wubbels said, adding the police "did a really good thing today. And that’s a highlight for what comes out when good cops do good work."Watch the original body camera video here: 4923
