Laverne Renz lives alone in her home near Pittsburgh. At 85-years-old, Renz is not as independent as she used to be, but she has plenty of energy.“I have to listen to her, or she’ll beat me up,” Renz jokingly said when asked about her caretaker, Rose Shenkel. The two have a playful relationship.But Shenkel is not always around, so Renz has a back-up caretaker.“Alexa, call Susie for me,” shouts Renz.She uses Amazon’s Alexa to make phone calls and to listen to her favorite music. Alexa is even setup to give Renz important reminders.“She reminds me when to take my medicine, when to eat my lunch. She reminds me of everything. She won’t leave me alone,” jokes Renz.But Shenkel said when she’s not there to keep Renz company, Alexa can step in.“It’s companionship for her. Artificial, but it’s companionship,” says Shenkel. “She spends a lot of time alone, so I think when Alexa comes on that perks her up, even when she wants to shut her up, it perks her up.”The technology can be more than just a voice to talk to. It’s also setup to be a lifesaver. 1065

LAS VEGAS – Over the last 25 years, a Las Vegas woman has become a beacon of hope for midwestern kids with dreams of going to college. Christina Hixson’s scholarship sets aside class ranks and GPAs. Instead, it looks for students who exhibit resilience, potential and pure grit. Family photographs line Hixson's Vegas office. Although she has no children and she never married, hundreds of young people look to the sharp 92-year-old with love, admiration and gratitude."I don't have a lot of money anymore, but I still give away," said Hixson.In 1995, she established an educational fund for Iowa high school students, awarding one-half college tuition scholarships to one student in each of the 99 counties in the state."We do not look for the honor students,” said Hixson. “We're looking for ordinary people to make their lives better."The fund is geared toward those who face extraordinary hardships with courage and fortitude, offering them a chance to study at Iowa State University in Ames."She's looking for the student who's had to work their way through high school and isn't a star student," said Allison Severson, Director of the Hixson Award Program at ISU. She’s looking for students like Jackie Fisher. "I was a terrible student in high school,” said Fisher. “I got really bad grades. I never did my homework because I just didn't care."Once homeless, Fisher broke away from a household that discouraged education. Next semester, she’ll be the first in her family to graduate college and not with just one degree, but two."I got the scholarship and it just kind of gave me the opportunity to actually go," said Hixson.ISU sophomore Cinestie Olson battled through depression and anxiety to become a Hixson scholar. "That was really difficult to go through so I just had to keep reminding myself you know keep going, you have college ahead of you, like you can totally change your life after this."Perhaps most interesting is that Hixson inherited the seed money for the foundation from her boss, businessman and philanthropist Ernst F. Lied. He died without heirs or instructions on what she was to do with the money."I hope he would be pleased with what we've done," said Hixson.A small box of notecards helps keep track of just how much money she's donated to a handful of colleges and universities. "We've given away 8,238,404," said Hixson.Hixson says faith in what these students will do with their gifts is why they were chosen. "Extraordinary things are done by ordinary people given a chance,” said Hixson. 2543

In the battle between the adolescent penchant for hitting the snooze button and parental desire to rush them onto an early morning school bus, experts say science is increasingly siding with the snooze.The biological clock of teens is shifted, Dr. Mary Carskadon, director of the Sleep and Chronobiology Research Lab at EP Bradley Hospital, told CNN. That means everything influenced by the circadian timing process, including sleeping, waking and eating patterns are set later.And if teens have trouble naturally falling asleep at an early hour and don't get the recommended eight and a half to nine hours of sleep, asking them to be awake, ready and in a classroom by 7:30 a.m. can wreak havoc on their systems, Carskadon said.Students in one state have gotten a reprieve from the early morning blues. California Gov. Gavin Newsom signed legislation Sunday that pushes back start times for middle and high schools to align with teens' circadian rhythms. It's a move sleep experts hope more school districts will follow.That's especially because research suggests that when teens get a later start in the morning, they can do a better job of checking off the things on many parents' priority lists like:Paying attention and getting their homework doneFour out of five public middle and high schools in the US start before 8:30 a.m., the earliest time recommended for teens, according to the US Centers for Disease Control.Carskadon says the negative consequences of early waking on academic performance are obvious: Students have more trouble concentrating in class and retaining information, feel tired during the day, have more absences and tardiness and have a hard time doing their homework and class reading well.There isn't enough time between when their clocks tell them to go to sleep and when they need to be in class to get the sleep they need, she says. And to make matters worse, for many teens, their bodies are telling them it's still time to be in bed when they are trying to listen in class."A lot of kids will just be asleep in first period because their brains are -- almost literally -- on the pillow and not yet in the classroom," she said.Avoiding the junk foodWhen students are off of their regular sleep cycle, they often also fall off of their ideal eating cycle too, Carskadon said. Since the biological clock influences humans' eating, straying from the circadian rhythm could mean eating too much or eating the wrong food at the wrong times, she said.Who among us reaches for a healthy snack when we are tired and awake when we aren't supposed to be, asked Stacy Simera, a licensed social worker who is chair of the sleep committee for the Ohio Adolescent Health Partnership.That disruption not only means worse nutrition, but it can lead to an increased risk for Type 2 diabetes, Carskadon said.Staying out of troubleWhen it comes to impulse control, Carskadon and her colleagues say teenagers already have the accelerator pushed down without any breaks. That's because the emotional side of the brain is well developed in those years, but doesn't have a very strong link to the executive decision-making side.And neuroimaging studies showed that link is even weaker in teens without enough sleep. The result can be trouble controlling their impulses and increasingly engaging in risky behaviors like foregoing helmets, driving under the influence and abusing substances, Carskadon said.Keeping happy and safeFrom a physical health perspective, teens who get adequate sleep also are shown to suffer fewer car accidents and sports injuries, said Simera.She says teens fall asleep easiest and get the best quality sleep from 11 p.m. to 8 a.m. -- the sweet spot. And research shows that straying from that sweet spot and sleeping less is correlated to depression, anxiety and suicide, she said.One study found that for each extra hour of sleep adolescents get, 3899

Is she smiling or is she upset as she stands with one hand touching her necklace, the other clutching her phone? The last known images of Mackenzie Lueck, 23, released by the Salt Lake City Police Department on Tuesday, offer few clues.In the still shots snatched from Salt Lake City International Airport videotape, Lueck is seen wearing a black backpack and carrying a stylish handbag as she exits the airport's departure area sometime after 2 a.m. on Monday, June 17. Lueck had arrived at the airport after attending a family funeral in California. She texted her mother at 1 a.m. Monday when she landed in Salt Lake City, according to 651
