Sen. Rand Paul defended why he opted to not self-quarantine while awaiting for the results from a COVID-19 test he took last week. On Sunday, Paul's office announced that the the U.S. senator from Kentucky tested positive for coronavirus. Paul's office said he was asymptomatic and feeling fine. Paul continued to work on Capitol Hill until he learned of his positive test.Although Paul was not around many staffers, he was in close proximity of a number of fellow senators. Republican senators Mitt Romney and Mike Lee opted to self-quarantine following Paul's announcement. Paul's office said that staffers began working remotely 10 days ago and he had virtually no direct contact with his staff. “Given that my wife and I had traveled extensively during the weeks prior to COVID-19 social distancing practices, and that I am at a higher risk for serious complications from the virus due to having part of my lung removed seven months ago, I took a COVID-19 test when I arrived in D.C. last Monday," Paul said in a statement. "I felt that it was highly unlikely that I was positive since I have had no symptoms of the illness, nor have I had contact with anyone who has either tested positive for the virus or been sick."The CDC issued the following guidelines for testing:Hospitalized patients who have signs and symptoms compatible with COVID-19 in order to inform decisions related to infection control.Other symptomatic individuals such as, older adults (age ≥ 65 years) and individuals with chronic medical conditions and/or an immunocompromised state that may put them at higher risk for poor outcomes (e.g., diabetes, heart disease, receiving immunosuppressive medications, chronic lung disease, chronic kidney disease).Any persons including healthcare personnel, who within 14 days of symptom onset had close contact with a suspect or laboratory-confirmed4 COVID-19 patient, or who have a history of travel from affected geographic areas5 (see below) within 14 days of their symptom onset.Paul believed he should have been tested because of a preexisting condition."The nature of COVID-19 put me – and us all – in a Catch-22 situation," Paul said. "I didn’t fit the criteria for testing or quarantine. I had no symptoms and no specific encounter with a COVID-19 positive person. I had, however, traveled extensively in the U.S. and was required to continue doing so to vote in the Senate. That, together with the fact that I have a compromised lung, led me to seek testing. Despite my positive test result, I remain asymptomatic for COVID-19."Although Paul was the first senator with a confirmed positive test, two members of the House confirmed positive coronavirus cases last week. 2706

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

SACRAMENTO, Cali. -- A woman in California is recovering after being impaled in the leg by a large metal bar that fell off a big truck while traveling on the highway, according to officials.The unnamed victim was riding in a car on Highway 99 in Sacramento on Saturday, when the metal bar fell off of the truck in front of them, authorities said."The metal bar then bounced up and entered the right front of the Chevy, traveled through the engine compartment and entered the passenger compartment of the Chevy and impaled the right leg of the right front passenger," the California Highway Patrol's South Sacramento division said 642

Scientists have discovered a "monster black hole" so massive that, in theory, it shouldn't exist.It's a stellar black hole — the type that forms after stars die, collapse, and explode. Researchers had previously believed that the size limit was no more than 20 times the mass of our sun because as these stars die, they lose most of their mass through explosions that expel matter and gas swept away by stellar winds.This theory has now been toppled by LB-1, the newly-discovered black hole. Located about 15,000 light years away, it has a mass 70 times greater than our sun, according to 601
