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 romaine lettuce outbreak has many consumers thinking about where their crops are grown.One rooftop greenhouse company in Chicago says their lettuce is safer and longer-lasting.Jenn Frymark, the chief agriculture officer and manager of Gotham Greens, pulls out a head of lettuce and immediately starts to eat it."No, you don't need to wash it,” Frymark says. “We don't have that on our package, but there's no reason for me to wash it. I never wash any of our lettuce at home. It's amazing; nothing touches it; it’s so clean.”Here at Gotham Greens, lettuce is grown differently.  They do it hydroponically. That means it’s grown without soil, but in a nutrient-rich water. Instead of a traditional farm field, this lettuce is grown on rooftop greenhouses.Their space on Chicago's south side is the largest rooftop greenhouse in the country.  Because of the controlled environment, crops can grow in a third of the time of a traditional field.“We're giving this plant everything it wants: the right day temp, the right night temp, the nutrients, CO2 levels, air circulation, the water,” Frymark explains. “I mean, these are very coddled plants and they have everything they need, and they can just grow in this perfect environment and reach maturity very quickly.”Gotham Greens sells to grocery stores in the Chicago and New York metro areas, as well as select Whole Foods stores. The product goes from the greenhouse directly to grocery shelves in a day and a half.The company’s lettuce also lasts longer than the traditional grocery lettuce out here. Frymark says their product can last up to two to three weeks in the fridge. Additionally, Gotham Greens prices are comparable to other organic produce.Frymark also says their method dramatically lowers the risk for foodborne illness.“There [are] no manures, there’s no water sources that could be contaminants,” she says. “We don't have birds and animals getting into the field.”She says the company is expanding and plans to open more rooftop greenhouses in the near future. 2053

The three wildfires currently burning in California are moving across land with a terrifying speed.At its fastest, the Camp Fire in Northern California spread at more than a football field a second, or around 80 football fields per minute. It burned through 20,000 acres in less than 14 hours on Thursday. By Friday, it had reached 90,000 acres.PHOTOS: 3 wildfires rage in CaliforniaThe Woolsey Fire in Ventura and Los Angeles counties doubled in size in a 90-minute period Friday morning, to 8,000 acres -- by Friday evening, it was up to 35,000 acres.The Hill Fire in Ventura County torched 10,000 acres in six hours Thursday.Why are the fires moving so quickly?The combination of strong offshore winds that have been gusting as high as 70 mph, humidity values in the single digits and extremely dry conditions are leading to the perfect conditions for wildfires 872

The White House on Monday blamed Hamas for the deaths of 52 Palestinians who were killed by Israeli security forces during mass protests in Gaza on Monday."The responsibility for these tragic deaths rests squarely with Hamas," White House deputy press secretary Raj Shah said. "Hamas is intentionally and cynically provoking this response and as the secretary of state (Mike Pompeo) said, Israel has a right to defend itself."Pressed repeatedly on whether Israel bears any responsibility and asked whether Israel should show more restraint, Shah again pointed the finger at Hamas -- seemingly absolving Israel of responsibility."We believe that Hamas is responsible for these tragic deaths," Shah said, adding that the terrorist group bears "responsibility for the entire situation right now."The 52 deaths on Monday came on the 70th anniversary of Israel's independence while a delegation of US officials joined Israeli leaders to mark the opening of the new US embassy in Jerusalem. Trump's decision to recognize Jerusalem as Israel's capital and move the US embassy to the city in December has ratcheted up tensions in the region, where Israelis and Palestinians have competing claims to the holy city. The city is home to holy sites from three major religions: Christianity, Judaism and Islam.Israeli forces used lethal and nonlethal means on Monday in an attempt to disperse mass protests that took place at the security fence between Gaza and Israel, which included some Palestinians attempting to cross into Israel.Tuesday marks the "Nabka," or Catastrophe, which remembers the 700,000 Palestinians who were driven from, or left, their homes during the Arab-Israeli war that came with the creation of the Israeli state. 1734
