A missile which brought down Malaysia Airlines Flight 17 in eastern Ukraine nearly four years ago was fired from a launcher belonging to Russia's 53rd anti-aircraft brigade, investigators said Thursday.The Buk missile was fired from a farm near Pervomaisk, the Joint Investigation Team into the MH17 disaster told a news conference in the Netherlands."At the time this area was under control of pro-Russian separatists," said Fred Westerbeke, chief prosecutor of the National Prosecutor's Office of the Netherlands. The Buk launcher of the 9M38 series "was transported from the territory of the Russian Federation and was returned to that territory of the Russian Federation afterwards." 695

A Massachusetts school district is waiting to see how many students test positive for the novel coronavirus after one student came to school after testing positive for the virus. Almost 30 teens had to go into quarantine. The student in question reportedly got the positive test results on Friday, Sept. 11, and still went to school the following Monday.Are there legal ramifications to knowingly going out in public spaces while infected with COVID-19?Mike Lawlor, an associate professor of criminal justice at the University of New Haven, says there are two types of law that could be at play: criminal law and civil law.If someone gets infected and you can trace it back to a specific exposure where the person knew they had COVID-19, then that would be a case of reckless endangerment."Almost every state has a law like this. On top of that, if you can show that people intentionally did this and it’s certainly conceivable that someone intentionally tried to expose people to the virus-- if you can show that they actually got the virus-- then that would be an assault," explained Lawlor.But Lawlor says whether criminally prosecuting is a good idea or not is debatable. What is more likely is a civil case in the form of negligence or willful misconduct."This does have a cost when you do it, right? There’s an emergency cleaning operation that has to take place. These other students have to be provided for in distance learning. And if anyone were to be able to demonstrate they were exposed and became positive, the health consequences of that could be very significant," said Lawlor.He says, either way, both the student and the parents run the risk of criminal prosecution. 1692

A team at the University of Kentucky is researching a possible treatment for COVID-19 and key helpers are three alpacas; Big Boy, Blue Eyes and Emperor.“It’s a powerful technology that we have at UK (University of Kentucky) and it’s something that hopefully we can develop some therapeutics with,” said Wally Whiteheart, a professor in the Department of Molecular & Cellular Biochemistry.Alpacas, along with llamas and camels, make a special kind of antibody called a nanobody. Nanobodies can be useful in cancer research and for other diseases. Researchers, led by Whiteheart and fellow professor Lou Hersh, are working with a nearby ranch to see what impact alpacas could have on COVID-19.“We, in a sense vaccinate them, and this case with viral proteins, and we make nanobodies to those viral proteins,” explained Whiteheart. “We can then go and purify and identify the nanobodies that bind to the virus and then test them to see if they can inhibit viral infection.”Making the nanobodies is just the first step. The team will see which, if any, can block virus infection and those candidates could move on to clinical trials.There’s still a lot of research and testing to go, and also still a lot of hope.“The cool thing which we’re exploring now is the fact that you might be able to use them as a nasal spray and this actually gets them to the place where the virus is affecting lung tissue,” said Whiteheart.This isn’t the first time the trio of alpacas has helped medical research. Big Boy, Blue Eyes and Emperor have contributed to the university’s nanobody research for more than three years. In that time, they have helped researchers generate more than 50 nanobodies to target proteins involved in a variety of human diseases including cancer, diabetes and neurological disorders.This story was originally reported by Alex Valverde on LEX18.com. 1869

A Philadelphia woman is hailing a Cleveland Clinic doctor a hero after he helped save her life while on an airplane. On Saturday, 28-year-old Ashley Spencer boarded an American Airlines flight in Philadelphia destined for Cleveland. But shortly after the plane took off Spencer passed out."I stopped breathing," she said. "I still had a pulse. That's when the stewardess said, 'Is there any medical professionals on the aircraft? It's an emergency.'" Spencer, who has a severe peanut allergy, was having an allergic reaction to a bag of chips she had eaten right before the flight. Her body was going into anaphylactic shock. That's when Dr. Erich Kiehl, an electrophysiology fellow from the Cleveland Clinic, and another doctor from North Carolina sprang into action. The men injected Spencer with an Epi-Pen four separate times and monitored her vitals over and over.To make matters even scarier, Spencer suffers from Eosinophilic granulomatosis with polyangiitis (EGPA), a rare auto immune disease. Because of the disease, she said her heart isn't in the best shape. She's spent the last several years in and out of the hospital undergoing several rounds of chemotherapy."When a person is going into anaphylactic shock it has to be taken seriously," she said. "Having Dr. Kiehl on board was so important. He was monitoring the heart completely." The plane made an emergency landing in Pittsburgh and Spencer was rushed to the hospital. She spent Saturday night in the ICU recovering from the reaction. Spencer said she's gone into anaphylactic shock in the past and has received treatment at the hospital, but the help she received from the men in the air was above and beyond."I would have to say the treatment I got on an aircraft was probably better," Spencer said.What's ironic is that Spencer was on the plane to Cleveland because on Monday she's scheduled to meet with doctors at the Cleveland Clinic in her search for answers about her rare disease.Spencer said she is eternally grateful for both doctors who helped her on the plane. She's already purchased plaques for both men as a way to say thank you."I am beyond thankful," she said. "I could have died up there." Spencer said she hopes the Cleveland Clinic can help her meet up with Dr. Kiehl while she's in town.  2428

A preliminary report from the autopsy on Mollie Tibbetts' body determined that her death was a homicide resulting from multiple sharp force injuries, the Iowa State Medical Examiner said.Tibbetts, a 20-year-old student at the University of Iowa, went missing after an evening jog on July 18, sparking a major search in the region. A body that officials believed to be hers was found on Tuesday in a rural area, hidden under corn stalks, and the autopsy confirmed her identity.Cristhian Bahena Rivera, a 24-year-old Mexican man who illegally came to the United States, was charged with her murder on Wednesday after he confessed to following her on her run. In an arrest affidavit, Rivera said he remembered getting mad at her; what happened afterward was "blocked" from his memory. 789
