A University of North Carolina study warns against the use of THC or CBD by women who are in the early stages of pregnancy. The study, which was published this week, tested the use of both synthetic and natural cannabinoids on mice. The results found that one-time exposure to cannabinoids early in a pregnancy can cause growth issues in a developing embryo. UNC said that this was the first time a study of this kind has been performed on mammals. Researchers said that they found the effects of CBD and THC are potentially very similar to what is seen in fetal alcohol syndrome. The researchers added that cannabinoid use disrupted signaling between molecules and cells that control growth and development. Researchers believe the results on mouse fetuses would be similar to human fetuses.“The development of the embryo in this time period is very similar across all vertebrates,” said Scott Parnell, a member of the UNC Bowles Center for Alcohol Studies. “In this study we also test a synthetic cannabinoid in zebrafish that yielded similar growth deformations as the natural CBs. Having the same results across animal models reinforces our findings.”The researchers administered enough CBD that is considered a therapeutic range for humans. The THC concentration was of similar levels to smoking marijuana. “It is concerning how little we know about the use of marijuana, its CBs, and products like CBD oil during pregnancy,” Parnell said. “We know that there is no safe period to drink alcohol during a pregnancy, and I think this research shows the same is likely true of marijuana use.”To read more on the study, click 1639

Airlines in multiple countries have suspended the use of Boeing's new 737 MAX 8 aircraft over concerns about its safety, after an Ethiopian Airlines flight of the same model crashed Sunday killing all 157 on board.Flight ET302 to Nairobi had just taken off from the Ethiopian capital of Addis Ababa Sunday when it reported technical problems and asked for permission to turn back. It crashed shortly afterwards.As the crash investigation got underway, the Civil Aviation Administration of China ordered Monday that all domestic Boeing 737 MAX 8 jets be out of the air by 6 p.m. local time, due to its principle of "zero tolerance for safety hazards."China has one of the world's largest fleets of Boeing 737 MAX 8, operating 97 of the planes, according to Chinese state-run media.The move was followed by an announcement from Ethiopian Airlines that the carrier had grounded its fleet of Boeing 737 MAX 8 jets as an "extra safety precaution." Cayman Airways also said on Monday it was grounding both of its "new Boeing 737 MAX 8 aircraft ... until more information is received."Sunday marked the second time in less than six months that a new Boeing aircraft crashed just minutes into a flight. A Lion Air Boeing 737 MAX 8 flight went down over the Java Sea last October, killing all 189 people on board.Both crashes are under investigation and there is no evidence of a link between the two, but similarities in the incidents have prompted caution among some airlines."Given in both air crashes, the aircrafts were newly delivered Boeing 737 MAX 8, and both accidents occurred during the take-off, they share certain similarities," the Chinese administration said in a statement. It added that it would contact Boeing and the US Federal Aviation Administration to confirm "flight safety" issues before allowing the planes to fly again.Mary Schiavo, a CNN aviation analyst and the former Inspector General of the US Transportation Department, called the two incidents "highly suspicious.""Here we have a brand-new aircraft that's gone down twice in a year. That rings alarm bells in the aviation industry, because that just doesn't happen," she said.State-owned Ethiopian Airlines is one of Africa's leading aviation groups, and the continent's largest carrier by number of passengers.The Kenyan and Ethiopian governments announced a joint disaster response team on Monday to investigate the crash. Kenya's Cabinet Secretary of Transport James Macharia described it as a "very complex investigation."In a statement Sunday, Boeing said it was "deeply saddened" to hear about the loss of life in the Ethiopian Airlines plane crash."A Boeing technical team will be traveling to the crash site to provide technical assistance under the direction of the Ethiopia Accident Investigation Bureau and US National Transportation Safety Board," the statement said.Investigations ongoing after crashThe Ethiopian Airlines flight to Nairobi, in Kenya, lost contact with authorities shortly after takeoff at 8.44 a.m. local time, just minutes after it left Bole International Airport.Tewolde GebreMariam, Ethiopian Airlines CEO, said at a press conference Sunday that the pilot had reported technical difficulties and had been given clearance to return to the Ethiopian capital.An eyewitness told CNN they saw smoke coming from the plane before it crashed on Sunday.GebreMariam said a routine maintenance check hadn't revealed anything before takeoff. The pilot was a senior Ethiopian Airlines employee who had flown more than 8,000 hours and had an "excellent flying record," he added."As it is a fresh incident, we have not been able to determine the cause. As I said, it is a brand new airplane with no technical remarks, flown by a senior pilot and there is no cause that we can attribute at this time," GebreMariam said.Speaking on Monday, Kenyan Transport Secretary Macharia said relatives of the victims would be given "the utmost attention," including accommodation and flights to Ethiopia, if necessary.The US National Transportation Safety Board said on Sunday it would be sending a team of four to assist in the investigation into the crash.CNN aviation expert Richard Quest said while a "final determination" on the cause of the crash might be years away, information from the flight recorders should be retrieved within a matter of weeks.Global disasterCitizens of 35 countries were among the 157 people killed in Sunday's crash, including 32 Kenyans, 18 Canadians, nine Ethiopians and eight passengers each from China, Italy and the United States.The United Nations has announced 19 of their staff members were among the dead, including employees of the World Food Programme, the Office of the High Commissioner on Refugees and the Food and Agriculture Organization.Not all victims have been named, but some details have been released.The Ethiopian government expressed its "deepest condolences to the families," in a statement from the office of Prime Minister Abiy Ahmed. 4985

A total of 37 former Ohio State students filed a lawsuit against the school Wednesday alleging the university "actively concealed" its knowledge of actions by a doctor who they say was a sexual predator.Sexual abuse allegations against Dr. Richard Strauss -- who died by suicide in 2005 -- emerged last year after former Ohio State athletes came forward to claim the doctor had sexually abused them under the guise of a medical examination.The lawsuit says Strauss sexually assaulted and abused hundreds of male students and that "OSU officials aided, abetted, and actively concealed Strauss' sexual predation" on students."We agree with OSU president (Michael) Drake that there was an 'institutional failure' on the part of Ohio State to protect these athletes," attorney Michael Wright said. "It is our hope that OSU takes full responsibility for that failure."An Ohio State University spokesman declined to comment on the lawsuit Wednesday.The litigation comes about two weeks after an independent 1013
