Authorities say a seventh grader who died by suicide inside a northeast Ohio middle school bathroom last week planned to carry out an attack on the school.According to Jackson Township Police Chief Mark Brink, the Jackson Memorial Middle School student admired the Columbine shooters and had an eight-step plan to carry out an attack.The boy "intended to conduct a school shooting and harm others," Brink said. On Feb. 20, police responded to Jackson Memorial Middle School in Stark County after receiving a call about a student who had shot himself in the boy's bathroom.According to the medical examiner's office, the boy died from a self-inflicted gunshot wound to the head.Security cameras captured the 13-year-old on video coming out of the restroom with a .22 caliber semi-automatic rifle he had brought to school under his clothes. The boy went back inside the restroom and shot himself, police said.Investigators said it doesn't appear the boy shared his plan with anyone else, and he did not really have a presence on social media.Case of 13-year-old boy who shot himself inside Jackson Memorial Middle School has been ruled a suicide, according to the Summit County Medical Examiner. Boy passed away at Akron Children’s Hospital. @WEWS pic.twitter.com/JmlDIeLwbR— Bob Jones WEWS (@bobjonesTV) March 1, 2018 1354

As the world sputters amid a global coronavirus pandemic that may have originated from bats in China, researchers released a study on Monday indicating that pigs could transmit a pandemic-level flu strain to humans.The Chinese and British based researchers, who published their findings in the Proceedings of the National Academy of Sciences on Monday, said that G4 EA H1N1 viruses in pigs should be closely monitored in human populations, especially among workers in the swine industry.The researchers said that pigs are intermediate hosts for the strain of influenza, which researchers are concerned could spread to humans. A further concern is that humans could spread the virus to other humans, prompting a pandemic. While the study notes that the virus had spread to workers in the swine industry, it likely has not been transmitted from humans to humans.“G4 viruses have all the essential hallmarks of a candidate pandemic virus,” the team of UK researchers wrote.The researchers said G4 viruses bind to human-type receptors, produce much higher progeny virus in human airway epithelial cells, and show efficient infectivity and aerosol transmission in ferrets.While the study indicates cause for some concern, Martha Nelson, an evolutionary biologist at the U.S. National Institutes of Health’s Fogarty International Center, told Science Magazine the chances of a pandemic from G4 viruses are “low,” but added that no one knew the pandemic risk of H1N1 until 2009.“Influenza can surprise us,” Nelson told Science. “And there’s a risk that we neglect influenza and other threats at this time” of COVID-19.Nelson added to Science that given the warning, it would be ideal to produce a human G4 vaccine as the world still needs to be vigilant on other pandemics besides COVID-19.Domestically, the University of Missouri reviewed the research. 1855

Authorities say a U.S. Navy training plane traveling from Florida has crashed in an Alabama residential neighborhood near the Gulf Coast, killing both people in the plane. Navy spokesman Zach Harrell says both people in the T-6B Texan II training plane died Friday. No injuries were reported on the ground. Foley Fire Chief Joey Darby told news outlets that responders encountered and extinguished a “large volume of fire” that had engulfed a home and cars. The crash occurred near the city of Foley and the town of Magnolia Springs. A Navy spokeswoman says the plane had flown out of Naval Air Station Whiting Field, about 30 miles northeast of Pensacola. 664

August is usually an exciting time to be an educator, as Teachers start decorating their classrooms and preparing for a new group of students.This year, however, many teachers are experiencing a new set of emotions.“My colleagues are fearful,” said Tanya Kitts-Lewinski, president of the Kenosha Education Association in Wisconsin.Kitts-Lewinski says many teachers are fearful of returning to campus during the COVID-19 crisis. Now, she’s calling out the safety of teaching during this pandemic, even virtually, saying some schools are requiring teachers to teach online from inside a classroom.“We can’t serve our students if we’re sick,” she said.Now a local law firm is preparing for the worst by offering free wills to teachers returning to classrooms."People are very scared, and this is the one thing I can do to help this group, and I'm committed to doing as much as I can," said Jim Brzezinski, a partner at Tabak Law in Milwaukee, Wisconsin.Brzezinski came up with this idea after talking with his wife, who is also a teacher. After posting this service online, the response was overwhelming."Within 12 hours of opening up this to teachers, we got about 300 requests within the first 12 hours," he said.We reached out to the Kenosha Unified School District, but they wouldn't talk on camera. Off camera, they said they plan on returning to school virtually, then reassessing the status of the pandemic and determining if and when it's safe to return to in-person learning."We frankly don't have enough educators to make our classrooms small enough to follow CDC guidelines," Kitts-Lewinski said, adding she won't feel safe returning to the classroom until the virus is fully contained."If we're not alive," she said. "We can't serve our students." 1764

Bad news: There is a small chance an asteroid will collide with Earth. The good news: Mankind has more than 115 years to prepare for it. According to a Washington Post report, NASA is preparing for possible tactics to deflect the asteroid Bennu, which will approach Earth Sept. 21, 2135. As of today, NASA rates Bennu's chance of striking Earth at one-in-2,700.The asteroid is roughly 1,600 feet in diameter, and would not be an Earth-ending event if it struck. But that doesn't mean it couldn't cause damage, especially if it struck near a populated area. Bennu is likely dozens of times larger than the object that struck near Chelyabinsk, Russia in 2013, causing hundreds of injuries, and thousands of broken windows. The event caused nearly million in damage to roughly 7,000 buildings. The 2013 event shows that even small objects are capable of causing massive damage. In 2016, NASA launched OSIRIS-REx, which will land on the asteroid and bring back samples. The information gathered could help NASA decide what steps it would take to deflect the asteroid. According to the Washington Post, NASA is working on a plan called the Hypervelocity Asteroid Mitigation Mission for Emergency Response, or HAMMER. NASA's HAMMER plan could involve using a nine-ton bulk impactor to push Bennu out of Earth's path. Another idea would be straight out of the movie "Armageddon," using a nuclear-type device to move the asteroid. A NASA engineer involved in the study told the Washington Post all of these ideas are theoretical. “We’re doing these design studies to prepare ourselves, so if we do find a threatening object, we’re better prepared to deal with it,” Brent W. Barbee, NASA engineer, told the Post.To read the Washington Post's full report, click here.  1855
