Regular nonstop flights between the east coast of Australia and London or New York could soon become a reality.In preparation, Australian airline Qantas has announced three test flights, with 40 people traveling directly from London or New York to Sydney, to see how the human body copes with 19 solid hours of air travel.Qantas previously announced its goal of operating direct flights between London, New York, and three Australian cities -- Sydney, Brisbane and Melbourne -- by 2023.The test flights scheduled for October, November and December will move the airline closer to that target and enable Qantas, alongside medical experts, to test the health and wellbeing impacts on passengers and crew.Bjorn Fehrm, an aeronautical and economic analyst at Leeham News, explains to CNN the appeal of the ultra-long-haul flight, as opposed to a more typical two-part journey stopping in Dubai or Singapore.There's no layovers, no extra journeys through customs and no transfer stress, he points out. "You can plan it so you fly over night, and you could arrive to actually have a productive day the next day as well," says Fehrm. "It's going to be businesspeople that fly this way."If the 19-hour flight becomes a reality, it's likely to cost travelers more. "It's cheaper for the airline to do two separate flights," Fehrm says. "But some people are prepared to pay the extra price of that ticket."Before the trials begin later this year, three Boeing 787-9 Dreamliners, fresh off the production line, will be flown from Boeing's factory in Seattle to either London or New York.After the test flights -- two from New York, one from London -- the new planes will enter commercial service. Most of the people on board the test flights will be Qantas employees, so seats won't be available for purchase.Researchers from Sydney University's Charles Perkins Centre, Monash University and the Alertness Safety and Productivity Cooperative Research Centre -- a scientific program backed by the Australian government -- will examine the impact of the long flight on those on board.Passengers in the main cabin will wear monitoring devices, and experts from the Charles Perkins Centre will study how their "health, wellbeing and body clock" are impacted by a set of variables that include lighting, food and drink, movement, sleep patterns and inflight entertainment.Monash University scientists will focus on the flight crew, recording their melatonin levels before, during and after the flights, as well as studying brain wave data from electroencephalogram devices worn by the pilots.This information will then be shared with the Civil Aviation Safety Authority "to help inform regulatory requirements associated with ultra-long haul flights," Qantas said in a 2765

Strong opioid dosage is the topic of a two-day public hearing by the Food and Drug Administration — which is trying to discern the benefits and risks.For Katrina King, her opioid addiction began with a back injury. It got so bad she spent two years behind bars after getting caught with forged prescriptions. King blames being put on high-dose medication too strong for her injury."The extended release — introducing that into the picture as such a potent dose so early in my diagnosis without trying anything else — ended up being catastrophic," she said.Some people have suggested the FDA remove high-dose opioids form the market to fight the deadly epidemic. Others argue the stronger meds are necessary to manage pain for some patients and getting rid of it could worsen pain for those people, leading to potential suicides."We don't want to cause additional suffering for people who have unmanageable pain that does make them feel they don't want to live anymore. On the other side of that, I would challenge the pharmaceutical industry and the FDA to come up with other methods of pain control," King said.The FDA will review public comments and decide whether to make change, which could include tougher regulations on reducing the use of high-dose opioids. 1276

Sen. Cory Booker, D-New Jersey, has endorsed former Vice President Joe Biden in the race for the Democratic presidential nomination.Booker made his announcement in a tweet early Monday morning."The answer to hatred & division is to reignite our spirit of common purpose. @JoeBiden won't only win - he'll show there's more that unites us than divides us. He'll restore honor to the Oval Office and tackle our most pressing challenges. That's why I'm proud to endorse Joe," Booker tweeted.Booker's endorsement is the latest boost in momentum for Biden's campaign, which has taken off since the former vice president's win in the South Carolina primary. Since that win, Biden racked up big wins in Super Tuesday primaries and picked up major endorsements from moderate candidates like Booker, Mike Bloomberg, Amy Klobuchar and Pete Buttigieg.Biden currently holds a slight delegate lead over Sen. Bernie Sanders (I-Vermont), with 664 delegates to Sanders' 573.Booker previously sought the Democratic presidential nomination and appeared in a number of debates, but dropped out prior to the Iowa caucuses. 1117

Right now, nearly 2 million people are living with limb loss in the United States. But new technology is bringing hope, with a prosthetic that responds to what a person is thinking. Whether it's picking out socks or picking up LEGO blocks, Mario Gasbarro seems to be doing it all just fine, using what his kids affectionately call his “robot arm.” “They seem to enjoy it more than my old arm,” Gasbarro jokes. At just 34 years old, Gasbarro’s doctors told him the lump that had been growing on his elbow was a malignant tumor. As it grew, his doctors determined amputation was his best option. “I don't need my left arm to be able to love my kids and love my wife and to be there for them, so that was always a priority,” Gasbarro says. Now, he’s living with this prosthesis, which moves based on how he thinks and moves his muscles. “I want to open my hand. I think, ‘OK, open my hand and move the muscles to open my hand,’ and I just need to replicate that muscle movement each time I want to try to open my hand,” Gasbarro says.Dr. David Schnur with Presbyterian/ St. Luke’s Medical Center worked with Gasbarro through the process. “Instead of the patient learning the prosthesis, the prosthesis really learns the patient,” Dr. Schnur describes of the prosthetic arm. Through a process called targeted muscle reinnervation, Dr. Schnur attached the nerves from Gasbarro’s forearm that power the hand to muscles in his elbow. “And then what happens is when Mario thinks about closing his hand, instead of causing a muscle to fire down his forearm, it causes a muscle to fire up in his in his biceps,” Dr. Schnur describes. Those signals are then picked up by his prothesis through pattern recognition. “He contracts the muscles. That makes sense for him to close the hand and the computer on the prostheses picks that up and is then able to convert that specific signal into a hand closed,” Dr. Schnur says. Gasbarro says it's not second nature just yet, but he's getting there with practice.“I’ve never felt limited, or like, I’m not able to do anything,” Gasbarro says. 2084
