As the coronavirus spread globally, a canceled work trip here and there turned into a worldwide shutdown for business travel by air.The global airline industry is now on the brink of collapse. And while pressing pause for a few days or a week is strange enough, a freeze on business-class travel that lasts for several weeks or months has the potential to reshape why people fly. After a decade of huge growth, airlines are preparing for a staggering drop in revenue worldwide. Concerns over the coronavirus have crippled demand for flights, which in turn has caused many airlines to ground their fleets and lay-off staff.Recently JetBlue CEO Robin Hayes called this financial situation for airlines, "at least as bad as 9/11 if not worse."But even with a bailout, it could take months for travelers to fully return to the skies. In the meantime, a lot of business will go on without air travel.With huge advances in telecommuting and a growing acceptance of working from home, businesses have taken to platforms like Slack, Zoom and Skype to carry on with meetings while many miles apart.To understand the impact of losing business class travel, you have to understand how valuable business class tickets are to airlines. It might just be a few seats, but on many flights, premium seats actually account for most of the money the flight will make. Let's explain.Let’s look at a roundtrip flight scheduled for the first week in August between JFK and LAX. The round trip fare for an economy passenger costs 9. For a business class passenger that seat is ,867. And finally for a first class passenger the cost is ,032. In total, if everyone pays full price for their ticket, the airline makes ,362.But notice the distribution. If you do the math, you see that although business and first class travelers only make up 28% of the passengers on the flight, they account for 60% of the flight's revenue. This model doesn't describe every flight. But when it comes to airline economics, business and first class passengers have an outsized impact on many airlines' revenue. "They care a lot about business class travelers," says airline pricing expert Andy Boyd. "The other part about the business class travelers is not just the seat but business travelers become very connected with their brand and they fly a lot. It’s not just the money they make from the one seat, but what they get over time."Boyd literally wrote the book on airline ticket pricing. He believes airlines could bounce back, but he also says the virus could accelerate some trends already in motion for business travel."It could be a catalyst," Boyd says. "But what is really interesting, the new generation has grown up with technology, with cell phones. The fact that you are doing what many older people would call, very informal communication is more and more accepted as formal communication. So as young people who have grown up with technology get older, they may find that they are just as happy doing things over the phone as they are getting on a plane and going somewhere."Those combined factors could spell long-term impacts for the airline industry beyond the spread of the coronavirus. "Normally I would tend to say we would just get over it and the world would just get back to normal," Boyd says. "But with this particular virus and the way that people have responded to it, we may see some actual real changes to the way that both business and economy travelers travel." 3474

As computers, tablets and cellphones have become a growing part of our lives, the exposure to blue light emitted from these devices increases. While blue light exposure has been known to cause strain in eyes, Oregon State University researchers studied the effect of blue light exposure on aging. Based on to their findings, exposure to blue light could cause aging to accelerate. For their study, researchers used common fruit flies and exposed them to 12 hours of blue LED light and 12 hours of darkness. To compare, researchers kept a group of flies in total darkness, as well as a group of flies that were exposed to light that had the blue wavelengths filtered out. The researchers said they chose fruit flies because their cellular and developmental mechanisms are similar to humans.The researchers said that flies exposed to blue LED light sustained damage to their retinal cells and brain neurons and had impaired locomotion. Even more stunning, some of the flies, which exhibited some brain damage, were mutants that did not develop eyes."The fact that the light was accelerating aging in the flies was very surprising to us at first,” said Jaga Giebultowicz, a professor of integrative biology at Oregon State. “We’d measured expression of some genes in old flies, and found that stress-response, protective genes were expressed if flies were kept in light. "We hypothesized that light was regulating those genes. Then we started asking, 'what is it in the light that is harmful to them,' and we looked at the spectrum of light. It was very clear cut that although light without blue slightly shortened their lifespan, just blue light alone shortened their lifespan very dramatically.” 1708

At its height, millions of smartphone users played along to HQ Trivia, a live trivia game show where anyone could win actual cash. Depending on the number of winners on a given night, winners could earn anything from pennies to thousands. But as of Friday, it appears the smartphone game is no more. HQ Trivia has suspended the service, the company announced on its app on Friday. CNN was first to report the news. CNN reported that HQ Trivia is laying off its remaining 25 employees. In an email obtained by CNN, CEO Rus Yusupov told employees, "Lead investors are no longer willing to fund the company, and so effective today, HQ will cease operations and move to dissolution."The service launched late in 2017, and turned its then host Scott Rogowsky into a celebrity. Rogowsky made appearances on various TV outlets, promoting the game. Rogowsky stepped down from the game in 2019. The app won a host of awards, and even was nominated for a Primetime Emmy Award for Outstanding Interactive Program. 1015

Be warned: This holiday season will be the busiest on highways in U.S. history, AAA says. This is in addition to 2019 being the busiest holiday travel period at the nation's airports in 16 years.A record 115.6 million Americans are expected to travel from Saturday, Dec. 21 through Wednesday, Jan. 1. The figure is expected to be the largest since AAA began tracking holiday travel. AAA estimates 104.8 million will travel by car, a record according to AAA, in addition to 6.97 million who will travel by plane and 3.81 million who will travel by train. AAA said there are a number of reasons why travel is expected to be high this holiday season. “Holiday cheer is at an all-time high this year, with unemployment at historically low levels, and noted improvements in both disposable income and household net worth,” said Paula Twidale, vice president, AAA Travel. “Travelers should be getting used to crowded highways and airports, as this marks the eighth straight year of new record-high travel volumes for the year-end holidays.”One bit of good news for travelers is that gas prices are expected to continue dropping through the holidays, although the national average will likely be slightly higher than last December's average of .37 per gallon. 1266
