The pilots of?Lion Air Flight 610 were engaged in a futile tug-of-war with the plane's automatic systems in the minutes before it plunged into the ocean, killing all 189 people on board.But investigators say they are at a loss to explain why the pilots didn't follow the same procedure performed by another flight crew the previous day when they encountered a similar issue.A preliminary report into the crash released Wednesday by Indonesia's National Transportation Safety Committee (NTSC) reveals more details about the final moments of Flight 610, but acknowledges many questions remain.Data retrieved from the flight recorder shows the pilots repeatedly fought to override an automatic safety system installed in the Boeing 737 MAX 8 plane, which pulled the plane's nose down more than two dozen times. 820

The man who taught thousands of kids -- and adults -- about grammar and math through song has died.Bob Dorough, the creator of 'Schoolhouse Rock' passed away at age 94.His granddaughter Corin Wolf didn't disclose his exact cause of death but told CNN that Dorough was diagnosed with cancer last year.From "Conjunction, Junction," to "I'm Just a Bill," Dorough's upbeat tunes helped educate thousands of viewers about simple math functions, rules of grammar and the legislative process.'Schoolhouse Rock' songs premiered in 1973 and ran on ABC from 12 years. The show came back on air in the 1990s for five more years. Today, the songs live on in YouTube videos -- some with millions of views. 700

The pandemic has added extra stress to our lives, but that's not stopping some of us from getting more sleep.New research from the University of Colorado Boulder and the University of Washington looked at how stay-at-home orders and social distancing guidelines have impacted college students' sleeping habits.They found that on average, students have been sleeping 30 minutes more per weekday and 24 minutes more per weekend day. They've also been keeping more consistent sleep schedules.This is similar to what a study of people ages 18 to 65 in Europe found during this same time.So, the big question now is whether these habits will continue now that stay at home orders are lifted.“One of the things we recognize is that when people who weren't getting enough sleep start to actually get better sleep because they can and they realize ‘wow that makes a difference in my life,’ a number of people choose behaviorally to go ahead and continue to get that better sleep,” said Ken Wright, integrative physiology professor at CU Boulder.As for the question about whether the quality of our sleep has improved, the study in Europe did look at that. It found on average, people have been seeing slight reductions in the quality of their sleep, but there are things you can do to help with this.“When they looked at the group as a whole, they found that those people who got exercise and got more sunlight during the COVID stay-at-home, they found that they actually had less reductions in their sleep quality,” said Wright.One negative result of the stay-at-home orders on our sleep in both studies – people have been going to bed later, both during the week and on weekends. Researchers say it will probably be healthier for us if we can start going to bed earlier now. 1776

The mother of a 14-year-old boy with autism, who was traumatized after a run-in with a Buckeye, Arizona officer, says she never expected that what happened to her son would spark a national discussion. Diane Leibel also said see police body camera video was also one of the hardest things she’s ever had to do. “It was excruciating honestly,” she said. “I’ve never heard my son scream like that before. I don’t understand how it even got there.” On July 19, a Buckeye Officer named David Grossman mistook Connor Leibel for a drug user. As he drove by a quiet neighborhood park, Grossman claimed he saw Connor putting his hand up to his face, giving him reasonable suspicion to handcuff and detain the boy. It turned out Connor was using a small string to “stim” – a coping mechanism common for people with autism.  Phoenix-based KNXV broke the story about the video on Monday afternoon. Since, reports about the incident have appeared on every local Phoenix station, some national shows, and it’s even been picked up by the New York Times. The reason: It’s sparking a debate about how officers deal and confront individuals with mental illness, other disabilities, and autism. “We were afraid that our child would be ridiculed or that something would happen somewhere along the line,” Danielle Leibel said. "I didn’t think it would be from a police officer.” COMPLAINT DISMISSEDThe day after the incident, Leibel filed a citizen’s complaint with the police department against Grossman, a “drug-recognition expert.” Weeks later, officials up and down Grossman’s chain of command cleared him of using unreasonable force and that he had reasonable suspicion to detain the boy. After the final decision, no one from Buckeye police notified Leibel, she said. “I’m every emotion I can think of. That’s my baby who was manhandled like that,” Leibel said. “I do see that would be reasonable to approach him if he saw him putting something to his face….But after he showed him what he had, that should have diffused the situation. It should end there.” Parents of other children with autism have told KNXV they are horrified by what happened and how the incident was handled by the officer. However, some people are also blaming Leibel’s parents and his caregiver for leaving him alone. His mother’s response: “He’s a 14-year-old. He’s higher functioning. He’s not a danger to himself or others…He plays in that park every week, and we’ve never had an issue.“I’ve never, in his 14 years, had an issue or have anybody suspect he was on drugs,” Leibel said. After the incident, Buckeye Police announced they are working on creating a voluntary register for people with disabilities, mental illness, and autism. They also proposed that those individuals wear bracelets. The registry would allow officer to look up specific information on people the come into contact with. Leibel and other parents of children with autism told KNXV they were disgusted by the idea. “I think it’s disgusting that you have to label someone with a disability with a special mark so they don’t have to live in fear of being hurt by police,” she said. “How would that have changed (the situation with my son) at all.” A parent of another child with autism who lives in Buckeye told KNXV the idea reminded him of the "Holocaust."  3418

The New England Journal of Medicine is one of the most popular medical journals in the world, where researchers go to share trials and information on data and science. But on Wednesday, the journal entered the world of politics.In an unusual and highly unprecedented fashion, the New England Journal of Medicine wrote a scathing rebuke of US leaders’ response to the coronavirus pandemic. While not formally offering any sort of endorsement, the journal referenced the upcoming election in its editorial. The piece did not name President Donald Trump or opponent Joe Biden by name.“Anyone else who recklessly squandered lives and money in this way would be suffering legal consequences,” the journal wrote. “Our leaders have largely claimed immunity for their actions. But this election gives us the power to render judgment. Reasonable people will certainly disagree about the many political positions taken by candidates. But truth is neither liberal nor conservative. When it comes to the response to the largest public health crisis of our time, our current political leaders have demonstrated that they are dangerously incompetent."The editorial, titled “Dying in a Leadership Vacuum,” comes just 27 days before the US election. While much of the world has been able to keep coronavirus deaths to a minimum in recent months, the US still has one of the highest death rates in the world from the virus related to the coronavirus.The United States continues to average 800 deaths per day from the coronavirus, according to Johns Hopkins University data. Only India has been averaging more deaths per day than the US in recent weeks, and India’s population is nearly quadruple America’s population.While many European nations saw a reprieve from the despair of the coronavirus over the summer, counties such as France and the United Kingdom are seeing cases jump in recent weeks, although their death counts still pale in comparison to the United States.The New England Journal of Medicine said that the US had every advantage going into the pandemic to combat the disease.“The United States came into this crisis with enormous advantages,” the journal’s editors wrote. “Along with tremendous manufacturing capacity, we have a biomedical research system that is the envy of the world. We have enormous expertise in public health, health policy, and basic biology and have consistently been able to turn that expertise into new therapies and preventive measures. And much of that national expertise resides in government institutions. Yet our leaders have largely chosen to ignore and even denigrate experts.”To read the full editorial, click here. 2657
