An astrological mystery event that lit up the daytime sky Wednesday over parts of the upper and midwest and southern Canada may have been solved.Scientists say the fireball was likely a rock that had escaped an asteroid belt between Mars and Jupiter a million or more years ago. They think the chunk of rock has been swirling near earth for awhile.“It’s probably been crossing the Earth’s path countless times, until its time was up in 2020,” Robert Lunsford, fireball report coordinator for the American Meteor Society, told Syracuse.com. “The chance of a collision is infinitesimal, but if you do it several million times, it finally happens.”Apparently the time to finally happen was around noon on Wednesday, December 2. Thousands of people reported seeing a bright streak of light lasting a few seconds, and thousands more heard the deafening boom.Reports came in from several states, including Ohio, Michigan, New York, Pennsylvania,Virginia, as well as parts of Toronto, Ontario and southeast Canada, according to the American Meteor Society.It’s not unusual for meteors to enter Earth’s atmosphere or make it to the ground, however this one was rare because it happened in a very populated area.NASA’s analysis of the event shows the meteoroid entered Earth’s atmosphere over upper New York, roughly between Rochester and Syracuse traveling roughly 56,000 mph. Which is slow by meteor standards.It then broke into pieces roughly 22 miles in the air, which produced the bright flash of light and loud sonic boom.NASA estimates the meteor was roughly three feet across and weighed about 1,800 pounds when it entered the atmosphere.NASA reportedly has three meteor-tracking cameras in Ohio and western Pennsylvania that could have precisely tracked this event, but they were off at the time because of the time of day.“Meteor cameras don’t turn on until night because they’re too sensitive to the sun,” explained Bill Cooke, who tracks meteors for NASA. 1966

ARROYO GRANDE, Calif. (AP) — Cal Fire alleges that fast food chain In-N-Out was responsible for a 2017 wildfire in rural Arroyo Grande, according to a lawsuit filed in San Luis Obispo Superior Court.The San Luis Obispo Tribune reports that Cal Fire claims the September 2017 wildfire was caused by a tractor mowing grass on In-N-Out property, saying it was covered in “dry annual grasses and scattered brush, which created a receptive bed of flammable vegetation.” The agency also claims the tractor was improperly maintained and the driver allowed the fire to spread.Cal Fire is seeking roughly .2 million from the burger chain to recoup costs.The fire burned about 245 acres (99 hectares) in four days. In-N-Out did not respond to a request from The Tribune.___Information from: The Tribune, http://www.sanluisobispo.com 832

Artificial turf has been a staple in many pro sports stadiums for about 50 years. And while there's no doubt that AstroTurf and its modern equivalent, FieldTurf, have changed the way pro football and baseball have been played, the surfaces have generally been considered safe for athletes to play on.But on Monday, the NFL Player's Association formally called on team owners to "proactively change all field surfaces to natural grass," citing higher rates of injuries to players who are playing on artificial fields.In an open letter, NFLPA President J.C. Tretter — a center for Cleveland Browns in the midst of his eighth NFL season — claimed that most of his teammates preferred to play on grass, noting that his joints felt "noticeably stiffer" after playing on artificial turf."The unforgiving nature of artificial turf compounds the grind on the body we already bear from playing a contact sport," Tretter wrote.In his letter, Tretter wrote that real grass offers more "give," reducing the stress on feet, ankles and knees. He also noted that NFL injury data shows players have a 28% higher rate of non-contact lower extremity injuries when playing on artificial turf.Tretter also noted that despite harsh conditions, cold-weather cities like Cleveland, Green Bay and Pittsburgh still use traditional grass fields. In addition, indoor stadiums in Las Vegas and Phoenix also use grass surfaces."Agronomically, natural grass field surfaces are possible everywhere," Tretter said.As of 2020, 17 of 31 NFL stadiums use traditional grass.Tretter's letter comes weeks after the NFL was forced to inspect the artificial turf at MetLife Stadium — home of the Jets and Giants — after several high-profile players were injured in the surface in the opening weeks of the season. Among those hurt during weeks 2 and 3 of the season were 49ers players George Kittle Nick Bosa, Jimmy Garoppolo and Raheem Mostert.In 2015, Houston's NRG Stadium switched from natural grass to an artificial surface after more than a decade amid player criticism over injury concerns. Due to its retractable roof, groundskeepers grew grass in trays outdoors and then brought the trays indoors and assembled them together with forklifts to form the playing surface. Players claimed the system created seams in the playing surface which led to injuries, and the stadium even faced a lawsuit from a former player who claimed the grass led to a career-ending injury.Tretter's Browns teammate, wide receiver Odell Beckham Jr., was lost for the season this week after suffering an ACL tear while playing on an artificial surface at Paul Brown Stadium in Cincinnati on Sunday. 2649

As disinfecting wipes and sprays fly off store shelves, companies are looking for new ways to keep surfaces coronavirus-free. Some are looking at repurposing UV light technology, a cleaning solution that’s been used for decades.Ava Robotics and the Massachusetts Institute of Technology partnered on a project to create a robot that uses UV-C light to disinfect large areas.“It was about a 4,000 square foot space. It was able to disinfect that in less than 30 minutes,” said Youssef Saleh with Ava Robotics.The purpose -- cleaning large, busy spaces of virus and bacteria, specifically coronavirus.“UV is not new. Robots are not new themselves,” Saleh said.“It's actually been in practice in hospitals for probably four decades plus,” said Dr. Eric Hill, the Chair of Emergency Services at Medical Center of Aurora. It’s usually used to sterilize rooms.“Anything that the light hits, it can kill. So it has to be in direct contact with the light beam and it has to be in contact for a certain period of time,” Hill said.“There are three factors of effectiveness of UV light, the first is the power itself,” Saleh explained. “Then there's the distance to the object that you're trying to disinfect, and then there is the amount of time.”"We cannot see it, it's the same kind of UV radiation you’d get from the sun,” Hill said. “It works by destroying the DNA and the RNA of the organism. And it doesn't affect just viruses, it affects bacteria, viruses, mold, and spores.”While it can kill germs, it can also do damage to us. UV light plays a role in diseases like skin cancer. “It is dangerous for humans to be in direct contact with it,” Dr. Hill said.That’s why the project with Ava Robotics and MIT also factors in safety for humans.“Safety elements have to be part of the solution, thought through, and understood,” Saleh said. The team is working on making the robot more adaptable to changing spaces, like warehouses, and potentially other large spaces like grocery stores and schoolsBut Hill says UV light isn’t a complete replacement for traditional cleaning methods.“It does not take the place of things like wiping something down,” he said. “But after you do that...adding in a UV light system can really hit in a broad area...and get all the microorganisms that were in there.”Hill also warns consumers that are interested in this to look at products closely.“Several hundred dollars is realistic for a good UV light system,” he explained. “We have seen much more of a demand of it, if you go on Amazon the amount of UV light products I’ve seen pushed out is incredible.” 2591
