Is anybody home? Astronomers have pinpointed two planets orbiting a nearby star that meet pretty much every requirement for supporting life. They're almost exactly the same mass as the Earth, they are billions of years old (which means life could have had time to evolve), and they're orbiting their star at a distance that would support things like water flow and habitable temperatures.The two planets orbit Teegarden's star, an ancient star that is only 12-light-years away from the Earth. ("Only" is relative -- 12 light-years is equal to 70,540,000,000,000 miles.) Research on the planets and their sun, 621

It is a truth universally acknowledged that middle seats on airplanes are the worst.Being awkwardly sandwiched in between two people while fighting for elbow room is the bane of most passengers. Now a new design might actually make people want the middle seat -- or at least make the 296

In a move widely expected to revive the national media spotlight on hate crime allegations made by "Empire" actor Jussie Smollett, a Chicago judge on Friday announced the appointment of a special prosecutor to investigate how local prosecutors handled the TV actor's case.In announcing his choice of former US Attorney Dan K. Webb as the special prosecutor, Cook County Circuit Court Judge Michael Toomin now gives an independent, experienced trial attorney the authority and time to examine why Cook County State's Attorney Kim Foxx dropped 16 disorderly conduct charges against Smollett after a high-profile Chicago Police investigation that lasted several weeks using dozens of investigators.Webb will have authority to file new charges, if deemed appropriate, against Smollett following his investigation.The gay black actor claimed in January that he was the victim of a hate-fueled attack, but police in February claimed Smollett staged it.Smollett, 36, was indicted on 16 felony counts but prosecutors 1021

It was a totally normal Tuesday in Chicago's Humboldt Park until someone spotted an alligator lurking in the park's lagoon.What started as a few eyebrow-raising photos turned into an intensive search as the Chicago Police Department and the city's animal control raced to find the animal. Sure enough, gator business was afoot.The police "independently confirmed the alligator is in the lagoon," 408

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
