The new virus is taking a broader toll on airline travel. Most airlines have already stopped flying to China.Now Delta Air Lines is sharply cutting back on flights between the U.S. and Seoul, South Korea, and Hawaiian Airlines is suspending all its flights to Seoul because of the outbreak. Delta said Wednesday it will suspend flights between Minneapolis and Seoul beginning this weekend and lasting until at least April 30. The airline will also reduce the number of flights from Korea to Atlanta, Detroit and Seattle. Delta, United and American have already suspended all flights to and from mainland China and Hong Kong for several more weeks. 660

The medical journal BMJ published a report today that links a lower risk of early death to higher levels of physical activity at any intensity in middle-aged and older people.Previous studies have repeatedly suggested that any type of sedentary behavior, such as sitting still, is not good for your health. Being sedentary for 9.5 hours or more a day, excluding sleeping time, is associated with an increased risk of death.Led by Prof. Ulf Ekelund of the Norwegian School of Sports Sciences located in Oslo, Norway, researchers analyzed studies that assessed how physical activity and sedentary time were linked with risk of an early death.Using accelerometers -- a wearable device that tracks the volume and intensity of activity -- to measure total activity, intensity levels were separated into categories of light, moderate and vigorous.Cooking or washing dishes were examples of light intensity, brisk walking or mowing the lawn were considered moderate intensity, and jogging or carrying heavy loads were used as examples of vigorous intensity.The risk of death for participants was approximately five times higher for those who were inactive compared to those who were the most active, according to the researchers.The study was conducted in the United States and Western Europe on 36,383 adults who were at least 40 years old with an average age of 62. Participants were tracked over an average of 5.8 years.However, the findings in the study may not apply to other populations and younger people.At least 150 minutes of moderate intensity or 75 minutes of vigorous physical activity each week are recommended guidelines, 1642

The Homeland Security Department is backing away from requiring that U.S. citizens submit to facial-recognition technology when they leave or enter the country.The department said Thursday that it has no plans to expand facial recognition to U.S. citizens. A spokesman said DHS will delete the idea from its regulatory agenda, where privacy advocates spotted it this week.The advocates and lawmakers accused DHS of reneging on repeated promises not to force American citizens to be photographed leaving or entering the United States, a process that is required for foreign visitors.Sen. Edward Markey, D-Mass., called the administration’s retreat “a victory for every single American traveler who flies on a plane.” He credited public pressure for the about-face. He said, however, that he still plans to introduce legislation to ban biometric surveillance of Americans.Edward Hasbrouck, a privacy advocate who pointed out the proposal, said the matter might not be settled.“Was this a trial balloon to find out whether the DHS had finally reached the limits of our willingness to be treated like criminals whenever we fly?” he said. “And if so, has the DHS partially backed off, at least for now? Maybe.”Customs and Border Protection officials say they originally considered including U.S. citizens in the biometrics program because having one system for Americans and another for foreigners adds complexity and could compromise security or make lines longer.But after meeting with lawmakers and privacy experts — including this week — it decided it was better to continue letting Americans opt out.Privacy experts have questioned the accuracy of facial recognition and warned that personal information could be vulnerable to hackers or used improperly by companies holding the data. In response to those criticisms, DHS made some changes, including shortening the time it will retain photographs from 14 days to 12 hours. Facial recognition is used to screen passengers at more than a dozen U.S. airports. Some airlines, including Delta and JetBlue, tout it as a convenience for passengers who no longer need to show boarding passes and identification. 2166

The NCAA is ruling out no contingencies when it comes to coronavirus and the NCAA Tournament. In an interview with Bloomberg News, Chief Operating Officer Donald Remy did not dismiss the possibility of games being played with no fans in arenas. The games presumably would still be televised. The NCAA declined further comment to The Associated Press on the possibility of no fans in the stands. Also, the NCAA announced it has established a coronavirus advisory panel of medical, public health and epidemiology experts and NCAA schools. NCAA Chief Medical Officer Dr. Brian Hainline will lead the group. 615

The National Weather Service routinely warns people about falling rain, snow and hail, but temperatures are dropping so low in South Florida the forecasters are warning residents about falling iguanas. NWS Miami posted Tuesday on its official Twitter that residents shouldn't be surprised if they see iguanas falling from trees as lows drop into the 30s and 40s. The low temperatures stun the invasive reptiles, but the iguanas won't necessarily die. That means many will wake up as temperatures rise Wednesday. Iguanas aren't dangerous or aggressive to humans, but they damage seawalls, sidewalks, landscape foliage and can dig lengthy tunnels. 657
