TEXAS CITY, Texas – About 45 minutes southeast of Houston, the Texas City Independent School District (TCISD) takes school security to a different level than most districts across America."We do think we're the school of 2030," said Mike Matranga.Texas City is just 20 minutes from Santa Fe High School where, two years ago, a gunman killed 10 people “You don’t hire a plumber to fix an IT problem," Matranga said. "You don't hire someone who is an educator to fix real world, mass violence problems." Texas City hired Matranga to overhaul school safety and gave him .5 million to do it.Mantranga is a 12-year Secret Service veteran who's been to dozens of countries and war zones."I would say the pressure is equal if not greater," Mantranga said of his role in Texas City. Classroom doors in schools now have reinforced glass and special locks.The district has hundreds of cameras in its 14 schools. At any point in time, around two-dozen can have facial recognition capabilities. Matranga's security team estimates the software is accurate about seven out of 10 times there is an alert.That's not the only software TCISD has invested in.Teachers have an app to alert the security team of a problem. The entire district can be locked down with a press of a button. Students can report tips online. The district has also invested in software that searches social media and the dark web. The district has also created behavioral profiles of each school. The profiles track issues like the amount of in-school and out-of-school suspensions to give the district a better idea of which students might be at risk. Matranga has faced criticism for his methods. There have been concerns the enhanced security could racially profile, violate privacy, or mis-identify students. “People need to stop being so sensitive," Matranga said. "Facts and data are facts and data. I don’t make them up. We take it and build from it and we identify kids at risk.”"I think that our society has gotten to a point where we are too politically correct where people are getting hurt," he said. But in an era that’s seen a number of high profile school shootings, it’s something Matranga says he won't be sorry about."If you don’t like what we’re doing, education is free. It doesn’t have to be at TCISD," he said. 2303

The number of young Americans watching online videos every day has more than doubled, according to survey findings released Tuesday. They’re glued to them for nearly an hour a day, twice as long as they were four years ago.And often, the survey found, they’re seeing the videos on services such as YouTube that are supposedly off limits to children younger than age 13.“It really is the air they breathe,” said Michael Robb, senior director of research for 469

  

The Hubble Telescope can sure find some scary images of deep space in a video released by NASA on Monday. The images were of the twin galaxies AM 2026-424, which is a mere 724 million light-years away from Earth. That means the light we are seeing on Earth was emitted 724 million years ago.From Earth, the colliding galaxies appear to form the shape of a face, with two "eyes," which make up the core of the galaxies."Each 'eye' is the bright core of a galaxy, one of which slammed into another. The outline of the face is a ring of young blue stars. Other clumps of new stars form a nose and mouth," NASA said in a statement.""Although galaxy collisions are common—especially back in the young universe—most of them are not head-on smashups, like the collision that likely created this Arp-Madore system," NASA added. "The violent encounter gives the system an arresting 'ring' structure for only a short amount of time, about 100 million years. The crash pulled and stretched the galaxies' disks of gas, dust, and stars outward. This action formed the ring of intense star formation that shapes the nose and face." 1129
