 Student safety is forcing parents to consider all actions to ensure their children are safe when heading off to school, and that includes buying bulletproof backpacks.Sales of the backpacks are surging and a backpack insert that stops bullets is also becoming popular. The backpacks are priced from anywhere between 0 all the way up to 0. The inserts cost anywhere between 0-0.The insert weighs less than a pound and fits in a backpack along with the students' books. The students are taught during to hold the backpacks in front of their chests in the event of an active shooter -- to protect their center mass.Bullet Blocker, the company that makes the inserts, saw a large spike in sales after the 2012 Sandy Hook shooting.Parents said they'll try anything to keep their children safe."My job is to protect him and when I can't protect him when he's at school, if I can give him something that will protect him, if that's what this world is coming to then I would absolutely do that," says parent Priscilla Graham. 1048

Would you have surgery performed if it was done by a robot? Robotic surgery is now an option at more hospitals across the country.Patient Matthew Canino says the technology helped his heart.“The nature of being a SWAT officer can be very taxing on your body,” Canino says. “So, you have to be in very good physical condition.”But when Canino trained, he noticed something was off.“My heart would race, primarily when I was working out, it would race,” Canino remembers. “And I'd get short of breath. And I kind of I would just stop what I was doing, and it would go away, and I thought everything was fine.”But it wasn’t. Canino’s doctors found out a valve in his heart was leaking.“He said if it wasn't repaired it would continue to get worse and would likely lead to heart failure,” Canino recalls.He thought he’d have to get open heart surgery. However, his doctor recommended a robot instead.“We can get inside the heart through these keyhole incisions on the side of the chest, without cutting through any bones,” says Dr. Sanjay Tripathi, cardiothoracic surgeon at Swedish Medical Center.Dr. Tripathi inserted this camera and robotic arms inside Canino’s chest, and then he sat down at a console inside the operating room where he controlled the robot to do the surgery.“With the robotic technology, particularly 3D high definition imaging from the camera, we're able to see these fine details that would otherwise be a little bit more difficult,” Dr. Tripathi says.Swedish Medical Center is the only hospital in Colorado offering cardiothoracic surgeries with the aid of a surgical robot. But they’re becoming available at more hospitals around the country, and patients are seeing big benefits.“Less pain,” Dr. Tripathi says. “Faster recovery, less bleeding, fewer infections.”“By the third day I was almost completely pain free and needed no pain medication at all,” Canino says.Not all heart surgeries can be done robotically, but the hope is as technology advances, that will change. 2006

 It just got a bit harder to find the latest issue of Cosmopolitan at Walmart.The retail company said Tuesday that it's removing the women's magazine from checkout lines. The National Center on Sexual Exploitation said Walmart made the decision following conversations with the anti-pornography organization."As with all products in our store, we continue to evaluate our assortment and make changes. Walmart will continue to offer Cosmopolitan to customers that wish to purchase the magazine, but it will no longer be located in the checkout aisles," Walmart said in a statement.While the move "was primarily a business decision, the concerns raised were heard," the company added.Cosmopolitan magazine, which is published by Hearst, is known for its sex tips and advice for young women. It covers "men and love, work and money, fashion and beauty, health, self-improvement and entertainment," and reaches millions of readers each month, according to Hearst's website.Hearst did not immediately reply to a request for comment.In a statement, the National Center on Sexual Exploitation lauded the "significant policy change.""Walmart's removal of Cosmo from checkout lines is an incremental but significant step toward creating a culture where women and girls are valued as whole persons, rather than as sexual objects," Executive Director Dawn Hawkins said.The group takes issue with the magazine, and believes customers shouldn't have to see it while checking out at stores, because it "places women's value primarily on their ability to sexually satisfy a man and therefore plays into the same culture where men view and treat women as inanimate sex objects," Hawkins said.The National Center on Sexual Exploitation, which changed its name from Morality In Media in 2015, works to highlight the negative effects of pornography, which it calls a "public health crisis." 1899

 People around the U.S. experienced some internet downtime on Monday. The outage was brief and service has been restored.The culprit was a configuration issue from Level 3, a telecommunications and internet service provider owned by CenturyLink. In a statement to CNN Tech, CenturyLink said a "configuration error" disrupted service and technicians restored service in 90 minutes.CenturyLink declined to provide further details.Though Level 3 was responsible for the issue, it affected other internet providers like Comcast. That's because Level 3's infrastructure delivers content for other internet services.Comcast said the service disruption to its Xfinity internet service has been resolved.According to reports from Down Detector, a website that monitors internet outages, Comcast and Level 3 connectivity was impacted nationwide beginning around 10 a.m. Pacific.Other internet service providers including Spectrum, Verizon, and AT&T showed a spike in connectivity issues, too, though they were not as widespread. (AT&T has agreed to acquire CNN's parent company Time Warner, and the deal is pending regulatory approval.) It's unclear if the spikes were related to the Level 3 outage.The website does not provide numbers of people affected.Following public complaints of widespread outages, rumors temporarily circulated online that the outage was a coordinated hack of some sort. But, as CenturyLink confirmed, it was a misconfiguration.CenturyLink completed its acquisition of Level 3 earlier this month. 1548
