Back to school time usually means it's time for a new backpack.Nowadays there are tons of choices in how kids can lug around their belongings. Rolling backpacks, shoulder sling options, or the traditional two-strap pack. But which one is right for them?Will it support their back? Stay together through the school year? Does it look good? These are some of the questions parents grapple with in the middle of shopping aisles.A study by UC San Diego researchers found that children commonly carry about 10 to 20 percent of their body weight in backpacks, which is also the limit recommended by the American Academy of Pediatrics.UCSD researchers tested the correlation between backpack weight and a child's back pain. They tested a group of 8 children and measured spinal pressure at three different amounts of backpack weight meant to mimic 10, 20, and 30 percent of their weight.They found that as the weight of the backpack load increases, back pain in children increases and spinal disc height shrinks as lumbar asymmetry grows.Which brings us back to the original question: How do you make sure a backpack is right for a child? A graphic from the folks at RetailMeNot have outlined how a backpack should rest on a child:Safety strapsBackpack straps are more important than kids think. Shoulder straps should be wide and padded to help distribute the pack's weight evenly, according to the website Healthy Children. Abdominal straps also help distribute weight across the waist, hips, and back.It's also recommended not to wear backpacks on only one shoulder, which shifts all that weight and leads to neck and back pain.Wearing it rightThe top of a backpack should sit one to two inches below the top of the shoulders. Also, the pack should not sit more than four inches below the waistline.The bottom of the backpack should align with the curve of the lower back.Preventing injury on the goWhile at school, its important for kids to be careful while lugging around their backpack. If possible, students should stop by their lockers often to unload any unneeded gear from their backpack. If bending down, kids should use both of their knees while wearing a backpack and not bend at the waist.Learning back-strengthening exercises can also help build up muscles primarily used while carrying weight.Consult a pediatrician if necessaryTalking with your child's doctor about back health is vital. Speak with your child as well about being vocal about back discomfort. And for parents, don't ignore complaints about back pain.If may also be worth speaking with school administrators about lightening the load of work carried around or buying separate textbooks to keep at home. 2740

At least five people have been killed in a ferocious storm that hammered the Northeast with powerful winds, relentless rain and historic flooding.The nor'easter moved out to sea Saturday, but not before it knocked out power -- perhaps for days -- to more than 900,000 customers from the mid-Atlantic to New England."People in these homes need to plan for a prolonged outage," Kurt Schwartz, director of the Massachusetts Emergency Management Agency, said Friday night. "This is a multi-day restoration event."RELATED:?'Bomb cyclone' pounds east coast with heavy flooding, high winds   The flooding is "the worst that we've seen in years," said Capt. John Dougan of the Quincy, Massachusetts Police Department, which had carried out more than 250 rescues between 8 a.m. Friday and midmorning Saturday. "We're seeing homes underwater, their basements were flooded out, the electricity was off."Emergency officials urged residents on higher ground to stay indoors, even after the storm pushed out."This is not a time to be out sightseeing and gawking, so please stay at home and stay out of our way," James Boudreau, the town administrator for Scituate, Massachusetts, said Saturday.Some 19 million people were still under a coastal flooding warning early Saturday afternoon.The storm morphed Friday into a "bomb cyclone" after undergoing a rapid pressure drop known as bombogenesis. It slammed much of the Northeast with heavy snow and rain, prompting significant coastal flooding and hurricane-force gusts in New England.Winds along parts of the Massachusetts coast that whipped in excess of 90 miles per hour are due to ease Saturday, CNN forecasters said.The storm also dumped heavy snow from Ohio to New England and into upstate New York, where more than 3 feet was recorded.Weak phone connection?

Aftermath response: The governors of Maryland and Virginia issued emergency declarations, allowing state and local agencies to help those affected.? Flight cancellations: About 250 flights in the storm zone were canceled Saturday, according to the flight-tracking website FlightAware.com. That compares with more than 3,000 US flights scratched Friday, most at the busiest Northeast airports in Boston, Philadelphia and New York.? Amtrak back in service: Amtrak resumed modified service at 6:20 a.m. ET Saturday, on its Northeast Corridor between Washington and New York, and planned to resume service between New York and Boston beginning at 8:40 a.m., the provider said.Five killed by falling treesAt least five people died in the storm, all killed by falling trees, authorities said. They include: a 77-year-old woman in Kingsville, Maryland; an 11-year-old boy in Putnam County, New York; a 44-year-old man in James City County, Virginia; a 6-year-old in Chesterfield County, Virginia; and a Newport, Rhode Island, man in his 70s.The 11-year-old was in his home when a large tree came crashing down, trapping him. A responding deputy tried to free the boy, whose mother was taken to hospital.Another young boy, just 6 years old, suffered a similar fate when a tree fell through his Virginia mobile home as he was sleeping on a top bunk bed. The boy was rushed to hospital, but his mother told the station his organs were failing."Doctors say we have to let him go," she told CNN affiliate WRIC. Cynthia Creighton's son was in her car when a neighbor's tree fell on top of the vehicle in Watertown, Massachusetts."The house shook, and we heard a noise. We didn't know what it was," Creighton told CNN affiliate WHDH. "We ran out, my son was still in the car with the tree on top of it."Creighton's son, who was in the back seat, was not injured, she said.Boston under waterHigh tides on Friday powered coastal flooding in Boston and other parts of Massachusetts, leaving streets awash for the second time since a massive nor'easter in early January.Kayakers paddled down Boston streets and National Guard members rescued 50 people from their homes in nearby Quincy, sometimes carrying them to safety in the scoopers of front-end loaders, CNN affiliate WBZ reported.Boston Harbor has only seen tides above 15 feet twice -- in 1978 and in January, during the last bomb cyclone. A high tide late Friday morning came up a little short, reaching 14.67 feet, but still sent water sloshing through the streets of East Boston.More record-setting high tides might strike Boston Harbor on Saturday during the midday high tide.With the moon full, the tide is at its highest point of the month, and the storm surge could drive as much as 4 feet of water into coastal neighborhoods, CNN meteorologists said. Massachusetts emergency officials said tides "will be astronomically high" in the next few days."I encourage all residents to be mindful of the storm and encourage employers to take the weather into consideration, which will mostly impact the coastal areas of our city," Boston Mayor Marty Walsh said.In Boston, many streets were closed and city officials advised people not to drive or walk in high water.Historic flooding prompts rescuesQuincy residents who were rescued from inundated homes told CNN they'd never seen anything like this weekend's flooding."It was pretty scary," said Alyssa Fitzgerald. "Once you saw the National Guard, that's when I was like, 'OK, we should have evacuated.'"Fitzgerald and her husband hunkered down overnight after their home lost power with their 3-year-old son and 1-year-old daughter, she said."Not like anything we've had before," Fitzgerald said. "Much worse than the snowstorm we had."Only a few storms even can compare with this level of flooding, including a 1978 blizzard, a storm in 1991 and January's bomb cyclone, Dougan, the Quincy police captain, said Saturday."We've been doing evacuations all through the night and today," he said.The-CNN-Wire? & ? 2018 Cable News Network, Inc., a Time Warner Company.

At X3 Sports, trainers have a goal of bringing out the warrior within their students by building up their cardiovascular endurance and their self-confidence.After being shut down because of COVID-19 concerns, this mixed martial arts gym in Atlanta is reopening and seeing a major increase in enrollment.“Since a lot of things have been going on in our community, it has increased at least 50% than what it was,” kickboxing coach Rica Grandison said.Grandison says more people are taking these self-defense classes and citing concerns ranging from the pandemic to the protests.She added that these students enrolling represent all races, genders and sexual orientations:“I am part of the LGBTQ community,” Grandison said.“I’ve been called the 'N' word just waiting for a bus. I’ve been called the 'D' word just hanging out with my partner, my significant other at the time,” she said. “So, I have been there.”Now the X3 coaches are sharing their championship credentials with gym members like Shannon Dunlap, who joined this gym to get stronger physically and emotionally.“I am a lot more comfortable in my body; I’m a lot more self-assured,” she said. “I don’t get nervous walking down the street.”The coaches at X3 say the more someone trains, the more muscle memory they will develop. Which means if they ever become a victim of an act of violence, it’s easier to escape that situation without things getting even more physical.“If somebody’s charging you just, just give them a push kick," Grandison said. “Push them away, knock them down, run away.”While Grandison says the best fight is a fight that never happens, she also believes it best for people to have the physical skills to defend themselves. 1714

As more and more public spaces open back up, many people are finding themselves a little jumpy when they hear someone cough nearby. Are they sick, is it allergies, is it coronavirus?Chances are, we are jumping to conclusions about those “sick” sounds we find disgusting, according to a recently published study from the University of Michigan and University of California, Irvine.“We find no evidence that perceivers can reliably detect pathogen threats from cough and sneeze sounds, even though they are reasonably certain they can,” said Nicholas Michalak, the study’s lead author and a University of Michigan psychology graduate student.In other words, we humans are not very good at distinguishing the seriousness of a cough or sniffle by the sound of it. In fact, the study found that the more disgusting a person perceived the sound to be, the more likely they were to believe the sound came from an infected person, regardless of whether it did.Previous research has indicated people can accurately diagnose infection in others using other senses, like sight and smell.The research is based on four studies that had participants judge whether a cough or sneeze sound came from people infected with a communicable (easily spread) disease or not. On average, participants guessed four out of ten sounds correctly.“Moreover, there was no evidence that accuracy improved when participants knew the true number of infectious sounds in advance or when participants focused on how clear or disgusting they perceived the sounds,” Michalak said. “Despite this poor overall accuracy, perceivers consistently reported reasonable certainty in their judgments.”The study’s authors theorized that people have a belief that a sound that disgusts them is likely to represent a disease threat - this could lead them to exhibit biases to avoid interactions with others who make disgusting but noninfectious noises, according to Mickalak.The study’s co-authors are Oliver Sng, assistant professor of psychological science at UC-Irvine, and U-M graduate student Iris Wang and U-M associate professor of psychology Joshua Ackerman.Read the full study here. 2150
