Boeing's 737 MAX jets will remain grounded for weeks after the Federal Aviation Administration said Monday afternoon that the plane maker continues to work on a software fix.Boeing had said it would submit the fix to the FAA last week, and it had gathered hundreds of industry representatives at its Seattle-area facilities last Wednesday to demonstrate the software changes.But the FAA said Monday that the company concluded "additional work" is needed."The FAA expects to receive Boeing's final package of its software enhancement over the coming weeks for FAA approval," the agency said in a statement. "Time is needed for additional work by Boeing as the result of an ongoing review of the 737 MAX Flight Control System to ensure that Boeing has identified and appropriately addressed all pertinent issues."Boeing acknowledged the new timeline, saying in a statement that the software change would be "completed in the coming weeks." It did not say why the timeline had changed."Safety is our first priority, and we will take a thorough and methodical approach to the development and testing of the update to ensure we take the time to get it right," the company said.American Airlines said Monday afternoon that it was aware the MAX "may be further delayed" in returning to service. It has been forced to cancel dozens of flights daily while the planes await a fix.American 1391

BRANDON, Fla. — A toddler has died after he was accidentally run over by his father driving an SUV in the parking lot of a Waffle House on Tuesday night. The Hillsborough County Sheriff's Office said the 3-year-old boy and his parents were leaving the Waffle House in Brandon around 9:45 p.m.According to deputies, the toddler's father and mother mistakenly thought the other had placed him inside their 2007 Chevy Tahoe. The toddler was transported to Brandon Hospital after his father struck him with the right front tire of the Tahoe, causing severe head injuries.Deputies said the toddler was pronounced dead at the hospital. Neither alcohol nor drugs contributed to the crash, according to HCSO. 712

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

Billionaire Mike Bloomberg has qualified for the next Democratic presidential debate. A new NPR/PBS NewsHour/Marist poll published Tuesday shows Bloomberg with 19% support nationally. It's the first time Bloomberg will stand alongside the rivals he has so far avoided by bypassing the early voting states and using his personal fortune to define himself through television ads. The former New York mayor will appear Wednesday in Las Vegas alongside Joe Biden, Bernie Sanders, Elizabeth Warren, Amy Klobuchar and Pete Buttigieg. His campaign says he's “looking forward” to it. The Democratic National Committee recently changed its rules for how a candidate qualifies for the debate, opening the door for Bloomberg. Tom Steyer hopes to qualify.Currently, former South Bend Mayor Pete Buttigieg and Sen. Bernie Sanders, I-Vermont lead the way in the in the 867
