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 Trump administration plans to raise pending tariffs on 0 billion in Chinese goods to 25% from 10%, a source familiar with discussions confirmed to CNN.The news was first reported by Bloomberg.The move, which is not finalized and could change, according to the source, comes as the United States and China remain locked in a trade war. Talks between US and Chinese officials have done little to ease tensions.The United States has already imposed 25% tariffs on Chinese goods worth billion. China immediately responded with its own tariffs on US goods worth billion.A second round of tariffs on products worth billion could take effect as soon as this week.US Trade Representative Robert Lighthizer earlier this month ratcheted up tensions when he released a list of thousands of additional Chinese exports worth 0 billion that could face 10% tariffs after a public comment period. It included fruit and vegetables, handbags, refrigerators, rain jackets and baseball gloves.Those tariffs, which might now be steeper, could go into effect as soon as September. 1108

The rescue of 11 hungry children in Amalia, New Mexico, on Friday began with a mysterious tip delivered to a detective across the country, in Clayton County, Georgia, from where young Abdul-Ghani Wahhaj vanished in November."We are starving and need food and water," read the message that provided the impetus for the raid on the rural compound near the Colorado border.New York imam linked to caseThere, authorities found the emaciated children -- the youngest 1, the oldest 15 -- in a squalid underground trailer, along with three women in their 30s, apparently the youths' mothers.After a standoff, police also took into custody two armed-to-the-hilt men -- one of them Siraj Wahhaj, 40, Abdul-Ghani's father.But they didn't find Abdul-Ghani that day. On Monday, investigators returned and found the remains of a young boy whose identity is awaiting confirmation, Taos County Sheriff Jerry Hogrefe said.Here's what we know of the youngster whose disappearance ultimately set the New Mexico raid into motion: 1018

The state of Massachusetts has ordered that children 6 months of age or older must obtain a flu vaccine by the end of December to attend any daycare, school or college in the state starting in January.The August 20 announcement was met with protest on Sunday. Hundreds held a protest in Boston, demanding the state rescind the order."They are forcing to inject something into our child and we don't agree with it,” protester Mike Megna told WBZ."I've been really stressed out about it. I am thinking of having home schooling until this gets reversed, but I am not going to let them pressure me to get the flu shot,” Jennifer Cordy also told WBZ. Cordy is the mother of 10-year-old student Xavier Cordy.But officials say that the flu vaccine is an important way for public health officials to reduce hospitalizations and deaths, even though the vaccine won’t provide protection from the coronavirus.“Every year, thousands of people of all ages are affected by influenza, leading to many hospitalizations and deaths,” said Dr. Larry Madoff, a medical director with the state's Department of Public Health. “It is more important now than ever to get a flu vaccine because flu symptoms are very similar to those of COVID-19 and preventing the flu will save lives and preserve healthcare resources.”The state is providing exemptions for medical or religious based reasons. Massachusetts is also exempting K-12 homeschoolers as well as college students who are fully off campus and do not attend in-person classes. There is not an exemption for K-12 students who are partaking in virtual learning through their school. 1620
