show that reading, juggling or learning and practicing a musical instrument improves the organization and structure of the brain's white matter.Before the MRI, the children were given cognitive tests, while the parents filled out a new scoring system on screen time developed by the American Academy of Pediatrics.The test measures how much access a child has to a screen (allowed at meals, car, in line at store?), the frequency of exposure (age started, number of hours, at bedtime?), content (chooses own? watches fighting or songs or education?) and "dialogic" interaction (does the child watch alone or does a parent interact and discuss the content as well?).The results showed that children who used more than the AAP's recommended amount of screen time, of an hour a day without parental interaction, had more disorganized, underdeveloped white matter throughout the brain."The average screen time in these kids was a little over two hours a day," Hutton said. "The range was anywhere from about an hour to a little over five hours."In addition, the tracts of white matter responsible for executive functions were also disorganized and underdeveloped (the parts of the brain shown in blue in the image)."These are tracks that we know are involved with language and literacy," Hutton said, "And these were the ones relatively underdeveloped in these kids with more screen time. So the imaging findings lined up pretty perfectly with the behavioral cognitive testing finding."'Neurons that fire together wire together'"These findings are fascinating but very, very preliminary," pediatrician Dr. Jenny Radesky wrote in an email. Radesky, who was not involved in the study, is the lead author on the American Academy of Pediatrics 1736

That is why this concept of digital safety and security is so important: because we know that this is happening. We know that sexts are being forwarded without consent, so if parents are having conversations with their teens about sexting, they can talk about those potential risks, Madigan said. 296

Team 10 asked if that policy was updated.

That work grew into a close relationship with the businessman-turned-politician, making Hicks one of the few White House aides who has avoided the infighting that has largely defined Trump's presidency. 202

The 76-seat Horizon Air turboprop plane took off without authorization around 8 p.m. local time, with a Horizon Air employee who was not a pilot at the controls, airport officials tweeted.After "doing stunts in (the) air" -- or being flown without proper skills -- for about an hour, the plane crashed at Ketron Island, the sheriff's department said. The man was a ground service agent, a job that includes directing aircraft for takeoff and gate approach, handling baggage and de-icing planes, authorities said.Video from a witness on the ground shows the plane at one point doing a loop, putting the aircraft upside-down, then pulling up just feet above a body of water.In light of the incident, airports nationwide will look at whether their security procedures need to change, CNN safety analyst David Soucie said. For one, the man shouldn't have been able to board the plane alone, he said."There is a protocol to not allow anyone singularly to get onboard an aircraft," Soucie said. "If you're going to access the aircraft ... you make sure that you check with someone else, and that someone else (will confirm) that ... you have the right authority to get onto that aircraft."This will be a major learning event for the aviation industry, CNN aviation analyst Justin Green said. 1285
