A Pennsylvania school district has a different solution for tackling intruders: rocks.Buckets full of river stones have been placed in all classrooms at the Blue Mountain School District in Schuylkill County, Superintendent David Helsel said.If students at the rural school district can't evacuate during a shooting, they don't have to sit and wait."Protocol has been that students lie down, under desks and basically become passive targets on our classrooms," Helsel said. "We decided to empower our students with tools of self-defense if needed."In a video posted online, the superintendent said the district decided to bring rocks to the classrooms after staff members took the active shooter response training, ALICE -- alert, lockdown, inform, counter and evacuate.The training taught them how to barricade doors with desks and chairs, and run away from gunfire. It also encouraged students to throw everything, from pencils to staplers, at potential shooters "rather than wait passively" for them "to attack.""At one time I just had the idea of river stone. They're the right size for hands, you can throw them very hard and they will create or cause pain, which can distract," Helsel told CNN affiliate WNEP.But they only see it as a last resort."We've learned many things from these tragedies over the years," Helsel said. "One of them is that evacuating makes students the safest."And if students can't leave the building, they'll have their stones."We understand that a gun is much more deadly than a stone. It's our hope that we can somehow stop the ability of an armed intruder to enter our classrooms," he added.Parents appear to like the district's plan."At this point, we have to get creative, we have to protect our kids first and foremost, throwing rocks, it's an option," parent Dori Bornstein told the affiliate.The-CNN-Wire 1851

A San Diego bail bondsman is disputing a controversial Facebook live in which the narrator says his agents were turning in a suspected undocumented immigrant.The video, shot Monday by Ryan McAdams, shows Watkins employees turning a Latino man into central jail. McAdams, wearing a Watkins hat, narrates the video, saying the man was at risk of skipping trial and costing Watkins ,000. He added commentary that drew criticism from immigration advocates. "He's in here hiding under sanctuary status right now," McAdams says in the nine-minute video. "Let ICE (Immigration and Customs Enforcement) deal with him."Jerald Watkins, who co-owns Watkins Bail Bonds, said he watched that video in shock. He said immigration status doesn't matter. "As long as you appear at your court dates, that's all we're asking," he said. Watkins said his workers took the man in after he changed his address and phone number, plus a warning from his co-signors that he may skip trial. "The family called and said look, this guy's acting shaky, we don't want to be on the hook for ,000," he said. Watkins said McAdams isn't his employee. He simply knew the agent, who let him ride along while he broadcast it on Facebook."Yeah, I'm not happy about that," Watkins said. "That's just some private citizen doing what he's going to do."McAdams told 10News Monday he wanted to inform the public."I'm just trying to keep people up to date," he said. But Watkins says immigration status had nothing to do with the case. In the Facebook video, McAdams said the man was suspected of driving under the influence. But Watkins said he was suspected of providing false information to police.He declined to identify the man.    1758

A non-profit in California has developed a way to capture poachers who snatch sea turtle eggs - building lookalike eggs with GPS trackers constructed inside them.According to research published Monday in the journal Current Biology, the InvestEGGator is a 3D-printed life-like turtle egg that can be tracked as far away as 137 kilometers (85 miles)."It replicates the appearance, weight, and feel of a real turtle egg. It is easily deployed at low risk to investigators, can be programmed and monitored remotely using web-based and smartphone applications, and is a low cost, allowing for deployment of many units at once," the company said on its website.The decoy eggs are placed in real nests alongside real eggs, which are monitored and mapped every time they are moved, said the Ventura-based Paso Pacífico, the non-profit that developed the eggs.The research showed that the decoy eggs provide a signal once every hour."Using data provided by the decoys, we identified trafficking routes and on two occasions properties of potential interest to law enforcement," researchers said in the journal. "Decoys also yielded anecdotal information, furthering our understanding of trafficking routes." 1206

A new study about video gamers pretty much shatters the stereotype many people have about them.Researchers at the Queensland University of Technology in Australia conducted what they say is the first study on body mass index from a worldwide sample of e-sports players. What they found surprised even them.“When we went into the study, we were kind of expecting that the gamers would have a much higher BMI than the general population, but what we found was the complete opposite. We found that players tended to have up to 21% more likelihood of being a normal weight,” said lead researcher Michael Trotter.The study included hundreds of participants from 65 countries. It showed gamers were between 9% and 21% more likely to be a healthy weight. Players also drank less and smoked less than the general population.Trotter started the university's e-sports program before he started studying for his PhD. He says he was surprised that serious players focused on their health almost as much as their playing. He says players requested a personal trainer, a dietician, and a sports psychologist.The study also found the healthier players were the better players.“We found that the players who were in the top 10% of all players and we measured up to 2.5 thousand players, it wasn't a small study. We found the top 10% of all players were exercising significantly more than their lower ranked counterparts,” said Trotter.Trotter says the growth of e-sports is huge and future programs will need to look at this study and realize they must focus on the health of players.He also says future research will need to be done on the overall health of e-sports players, such as muscle mass and bone density. 1706

A new medical device promises to diagnose a concussion in under four minutes and its creators are backed by a unique partnership between the NFL's Green Bay Packers and Microsoft.The world of traumatic brain injuries and concussions is filled with gray matter. The diagnosis is subjective and every doctor manages it differently as the injury is just as complex as the brain.“When you have a heart attack and go into the ER, you get five objective tests. If you get a brain injury and you go into the ER, you get, ‘Follow my finger, what month is it, who’s the president?’ We have to do better for brain-injured patients,” Dr. Rosina Samadani, CEO of Oculogica, said.Samadani developed a device called the "Eye Box.” Her sister, a neurosurgeon, discovered the technology.“Where it really came from was noticing that when there’s a deficit in the cranial nerves, there is a deficit in eye movements and there is that same deficit that occurs in concussed patients.,” Samadani said.So, she created an algorithm based on those eye movements, which is how the Eye Box was born.“We’re looking at your pupils, we’re tracking them and having you perform a simple task,” Samadani said. “You watch a video as it moves around the screen and we watch your eyes watching that video and that’s it.”The sisters took the idea to TitletownTech.“We look for exceptional founders who are solving meaningful problem,” said Jill Enos, the managing director of TitletownTech.The venture capital fund builds and invests in startups.“TitletownTech was formed out of this improbable partnership between the Green Bay packers and Microsoft, both of whom shared a common interest in advancing the technology capabilities of the region but also in leveraging the strength of startups and founders as economic drivers in the regional economy,” Enos said.Enos says Oculogica immediately caught their attention. And that is no easy feat. In just 15 months, more than a thousand ideas have crossed their desk. They've invested in 20; several are women and minority led.“As someone who is in venture capital, which is also not a very common women focused industry, it was great to see two strong founders that we could connect with and get behind,” says Enos.“We don’t feel that we’re so different than our peers but we are. We know we are and with that, we feel there is a great deal of responsibility,” Samadani said.She wants girls to love math and science like she does. And she says to realize that the sky is the limit.“We’re also very excited to show other women and young girls they can do this and women can be great at math and science. I wake up every single day and I’m so excited about what I’m doing and we’re changing the world of brain injury. Any woman, any young girl, can grow up to do this and that’s fantastic,” said Samadani.Oculogica is already authorized by the FDA, and the insurance and reimbursement codes are being worked out now. Some clinics already have it, and more are expected.“The best feeling is when we get a call from a mom or dad who says, ‘I'm so relieved we now know what’s going on,'” Samadani said. "'I didn’t know where to turn it.’ Just relieves their anxiety that is everything- absolutely everything when we get a call like that.” 3253
