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 smoke from dozens of wildfires in the western United States is stretching clear across the country — and even pushing into Mexico, Canada and Europe. While the dangerous plumes are forcing people inside along the West Coast, residents thousands of miles away in the East are seeing unusually hazy skies and remarkable sunsets.The wildfires racing across tinder-dry landscape in California, Idaho, Oregon and Washington are extraordinary, but the long reach of their smoke isn’t unprecedented. While there are only small pockets in the southeastern U.S. that are haze free, experts say the smoke poses less of a health concern for those who are farther away.The sun was transformed into a perfect orange orb as it set over New York City on Tuesday. Photographs of it sinking behind the skyline and glinting through tree leaves flooded social media. On Wednesday, New Jersey residents described a yellow tinge to the overcast skies, and weather forecasters were kept busy explaining the phenomenon and making predictions as to how long the conditions would last.On the opposite coast, air quality conditions were among some of the worst ever recorded. Smoke cloaked the Golden Gate Bridge and left Portland and Seattle in an ashy fog, as crews have exhausted themselves trying to keep the flames from consuming more homes and even wider swaths of forest.Satellite images showed that smoke from the wildfires has traveled almost 5,000 miles (8,000 kilometers) to Britain and other parts of northern Europe, scientists said Wednesday.The current weather system, which favors a westerly wind across the higher levels of the atmosphere, is to blame for the reach of the smoke, experts explained.“We always seem, at times, to get the right combination of enough smoke and the upper level jet stream to line up to bring that across the country, so we’re just seeing this again,” said Matt Solum with the National Weather Service’s regional operations center in Salt Lake City, Utah. “It’s definitely not the first time this has happened.”There could be some easing of the haze this weekend as a storm system is expected to move into the Pacific Northwest and could affect the conditions that helped the smoke travel across the country. But Solum said there’s always a chance for more smoke and haze to shift around.“Just due to all the wildfires that are going on, this is likely going to continue for a while,” he said. “You might have ebbs and flows of that smoke just depending on how the upper level winds set up.”Kim Knowlton, a senior scientist with the Natural Resources Defense Council in New York City, said she woke up Wednesday to a red sunrise and more haze.She said millions of people who live beyond the flames can end up dealing with diminished air quality as it’s not uncommon for wildfire smoke to travel hundreds of miles.Although the health impacts are reduced the farther and higher into the atmosphere the smoke travels, Knowlton and her colleagues said the resulting haze can exacerbate existing problems like asthma and add to ozone pollution. 3070

The University of Florida's football team is suspending activities following an “increase” in COVID-19 cases among members of the team, the university announced on Tuesday.The announcement comes just days after head coach Dan Mullen called on the university to open Ben Hill Griffin Stadium to a full capacity of 90,000 for the rest of the season. The state of Florida currently does not have a capacity restriction on stadiums."I know our governor passed that rule, so certainly, hopefully the university administration decides to let us pack the Swamp against LSU … 100 percent, because that crowd was a major factor in the game,” Mullen said following last Saturday’s 41-38 loss against Texas A&M. “So, I certainly hope our university administration follows the governor. The governor has passed a rule that we're allowed to pack the Swamp and have 90,000 in the Swamp to give us the home-field advantage Texas A&M had."The stadium is currently open at 20% capacity.Athletics director Scott Stricklin said the suspension was out of an “abundance of caution.”Sports Illustrated reported that the Gators had five new coronavirus cases identified on Tuesday.As of Tuesday afternoon, this Saturday’s game between Florida and LSU is still on as scheduled. 1269

The White House physician assigned to Vice President Mike Pence, Jennifer Pena, has resigned, his office told CNN in a statement Friday. Pena worked in the White House medical unit."The vice president's office was informed today by the White House Medical Unit of the resignation. Physicians assigned to the vice president report to the White House Medical Unit and thus any resignation would go entirely through the Medical Unit, not the vice president's office," Alyssa Farah, Pence's press secretary, said in a statement to CNN.This comes after CNN reported Tuesday that a Pence doctor privately raised alarms within the White House last fall that President Donald Trump's doctor Ronny Jackson may have violated federal privacy protections for a key patient -- Pence's wife, Karen -- and intimidated the vice president's doctor during angry confrontations over the episode.  890
