Two flight data recorders from Ethiopian Airlines Flight ET302 have been found, as airlines around the world ground Boeing 737 MAX 8s like the one which crashed Sunday, killing all 157 people on board.The plane's Digital Flight Data Recorder (DFDR) and Cockpit Voice Recorder (CVR) were recovered from the wreckage Monday, Ethiopian Airlines said in a statement. They will enable investigators and experts piece together the last moments of the flight, and should help explain why the new plane crashed.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 after.With investigations underway, multiple countries have suspended use of Boeing's new 737 MAX 8 aircraft amid concerns about its safety.On Monday, The Civil Aviation Administration of China ordered 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 China's 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 had crashed just minutes into a flight. A Lion Air Boeing 737 MAX 8 flight went down over the Java Sea in last October, killing all 189 people on board.Both crashes are under investigation. 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 2940

WASHINGTON, D.C. -- Super Tuesday’s presidential primaries across 14 states mark the first major security test since the 2018 midterms. State and local election officials say they are prepared to deal with everything from equipment problems to false information about the coronavirus. States have been racing to shore up cybersecurity defenses, replace aging and vulnerable voting equipment and train for worst-case scenarios since it became clear that Russia launched a sweeping and systematic effort to interfere in the 2016 presidential election. U.S. intelligence chiefs have warned foreign interference remains a threat for the 2020 election. And the recent outbreak of a new virus could present a bad actor with an opening to spread false information to keep voters away from the polls. 805

U.S. health officials estimate that millions of cases of heart disease and other illnesses are linked to abuse and other physical and psychological harm suffered early in life.In a report released Tuesday, the Centers for Disease Control and Prevention tried to estimate the impact of harmful childhood experiences on health in adulthood.Health officials acknowledged the study does not prove that these experiences directly cause certain illnesses. And they were not able to rule out other possible factors, such as the stress caused by financial family problems.But the link is strong, and is bolstered by many other studies, said Jim Mercy, who oversees the CDC’s violence prevention programs.“There’s a lot of evidence connecting these things,” and it’s become clear that the more harmful incidents a child suffers, the more likely their health suffers later, he said.For at least two decades, researchers have been looking at how suffering or witnessing traumatic events as a child affects the likelihood of physical injury or illness later in life.Researchers say such stressful experiences can affect how the body develops, and can also put a child on a path to smoking, drug use, and other unhealthy behaviors.The topic has been getting more attention in recent years from public health officials. California’s recently-appointed surgeon general has made childhood trauma and what is known as 1413

  

WASHINGTON, D.C. – Three different people who protected students from gunmen in 2018 and 2019 are being celebrated by the Congressional Medal of Honor Society. The society is honoring Oregon teacher Keanon Lowe, North Carolina student Riley Howell, and Texas student Christian Garcia with its 2020 Citizen Honors Awards. The awards are given to people and organizations that exemplify the values embodied Medal of Honor: courage, sacrifice, commitment, integrity, citizenship, and patriotism.Lowe and Howell are both being honored with the society’s Single Act of Heroism Award. Lowe, a teacher and coach at Portland’s Parkrose High School, made headlines in October when he disarmed a student with a loaded shotgun and then embraced him. He’s attributed with saving the lives of the students and faculty of the school. 832
