(KGTV) — 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.MORE: 10News back to school resources for parentsA 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. 2803

(CNN) - Walmart is betting it can convince time-strapped customers to let strangers deliver groceries into their refrigerators while they're away from home.In a new service announced Friday, customers will be able to order groceries online, and then a Walmart worker will drive the food from a nearby store and deliver it to fridges in customers' kitchens or garages. It is Walmart's latest innovation in its grocery business, which makes up more than half of the company's annual sales.Walmart piloted its new service in New Jersey for five months and is ready to expand. The option will be available to more than a million customers this fall in Kansas City, Pittsburgh and Vero Beach, Florida. Walmart charges a fee for regular grocery delivery orders, and it did not disclose how much customers will have to pay for in-home delivery.Here's how the service works: Customers can purchase groceries online and select a delivery day. Walmart's employees will wear a camera when they enter customers' homes, allowing shoppers to watch the process live from their phones. Customers won't have to pay for a camera, but they will have to purchase a special door lock. Walmart did not say how much the lock will cost.Walmart believes it can entice shoppers with another convenient perk as part of its in-home delivery service: Later this year, customers will be able to leave their returns from Walmart's website on their counter and the employee will bring the item back to the store.In-home grocery delivery is not an entirely new concept for Walmart. The company partnered on another grocery delivery option in 2017 with smart-security company August, which makes locks that customers can monitor on their phones. That test included drivers from a crowd-sourced startup to deliver the items to customers. Amazon launched Key in 2017 that allows delivery drivers inside customers' homes when they're not around.The biggest barrier Walmart will face with its new service is that most people don't want strangers in their homes.Bart Stein, a Walmart executive who leads the in-home delivery service, acknowledged some customers during the pilot test were initially skeptical of the concept. But he said Walmart had been able to change opinions once customers tried it out."We really saw the tables turn after one delivery during our pilot testing around how people would trust a service like that," he said.One way Walmart is trying to alleviate customer concerns about the service: A biography with three fun facts about their delivery employees.Walmart workers who've been at the company for at least a year can apply for the in-home delivery position. If they get the job, they will go through training and the role will become their main responsibility.Walmart US e-commerce chief Marc Lore did not say how many employees will be diverted to these new delivery jobs, but it's another skilled position the retailer has created as new technology emerges. Walmart has also created 30,000 "personal shopper" jobs in stores who select groceries for customers' online pickup and delivery orders.Walmart's new delivery model comes out of its tech incubator, Store No. 8. The incubator develops companies, such as Jetblack, Walmart's chat-based shopping service in New York City, that help it stay ahead of future shopping trends.Related: How to solve the world's plastics problem — Bring back the milkman"We're taking it out of Store 8 and bringing it into the core business," Lore said at a presentation to reporters on Thursday. Lore emphasized that Walmart will be able to use its own store network, grocery supply chain and employees for the service. He argued that combination will help distinguish the offering from competitors.Walmart has added thousands of grocery pickup locations from stores, same-day home delivery options and introduced voice ordering for groceries off Google Assistant. 3899

(CNN) -- House Republicans on Saturday submitted a list of witnesses they'd like to testify as part of the chamber's impeachment inquiry into President Donald Trump and Ukraine.In a letter to House Intelligence Committee Chairman Adam Schiff, Republicans listed the anonymous whistleblower, former Vice President Joe Biden's son Hunter Biden, former US special envoy for Ukraine Kurt Volker, high-raking State Department official David Hale and Tim Morrison, the top Russia and Europe adviser on the National Security Council. Saturday marked Republicans' deadline to submit the request.The GOP also requested Nellie Ohr, a former Fusion GPS contractor, and Alexandra Chalupa, a former Democratic National Committee staffer, signaling that Republicans still want to focus on unsubstantiated claims related to the 2016 presidential campaign.Democrats must approve any requests submitted by Republicans and they are expected to reject the requests for Hunter Biden and the whistleblower to appear.CNN has reached out to attorneys for the whistleblower and Hunter Biden for comment.In the letter, California Rep. Devin Nunes, the top Republican on the House Intelligence Committee, bashed what he called a "sham impeachment process." Nunes wrote that Republicans were calling the witnesses to testify in an open setting to "provide transparency to your otherwise opaque and unfair process."Schiff said in a statement later Saturday that his committee is evaluating the witness requests and "will give due consideration to witnesses within the scope of the impeachment inquiry, as voted on by the House."The House inquiry, he said, "is not, and will not serve, however, as a vehicle to undertake the same sham investigations into the Bidens or 2016 that the President pressed Ukraine to conduct for his personal political benefit, or to facilitate the President's effort to threaten, intimidate, and retaliate against the whistleblower who courageously raised the initial alarm."House Democrats are moving forward with their probe into allegations that Trump pushed Ukraine to investigate Joe Biden, the former vice president's son and the 2016 election in order to help the President politically and that the White House took steps to cover it up. Trump has denied doing anything improper.Trump has pushed an unproven accusation that then-Vice President Biden improperly tried to help his son by pressuring the Ukrainian government to fire the country's prosecutor general. Hunter Biden served on the board of the Ukrainian natural gas company at the time.There is no evidence of wrongdoing by either Joe or Hunter Biden in Ukraine.The Biden presidential campaign declined to comment to CNN Saturday on the request for the former vice president's son to testify. Joe Biden was asked Friday in New Hampshire whether he himself would testify at a Senate impeachment trial if asked -- though Republicans have not yet made that request."Let's focus on the problem, here," Biden said. "The question is, did the President of the United states violate the Constitution ... And did he profit from his office." He again called on Trump to release his tax returns.Impeachment hearings are set to begin next week as Democrats prepare to take their case against Trump to the public. The open hearings will be the first time the US hears directly from the officials at the center of allegations against Trump.Schiff has said three witnesses will testify next week: US diplomat Bill Taylor and State Department official George Kent will appear on Wednesday, and former US Ambassador to Ukraine Marie Yovanovitch is set to testify Friday.A review of more than 2,600 pages of transcripts released this week from eight witnesses who have testified in the House impeachment inquiry over the past six weeks shows how controversy over Trump's Ukraine policy had been brewing inside the US government for months.It roiled efforts to bolster a key strategic alliance after Trump enlisted his own personal attorney, Rudy Giuliani, to work outside normal diplomatic channels in an apparent effort to bolster his reelection chances. 4112
