More than 170 rescue workers are trying to free 18 coal miners trapped in a tunnel in China's eastern Shandong province, according to state broadcaster CCTV.The miners were trapped after a rock burst at the Longyun Coal Mining Company in Yuncheng County at around 11 p.m. (10 a.m EST) on Saturday.The incident destroyed part of a water drainage tunnel in the coal mine, killing two and trapping another 20 workers, the official Xinhua news agency reported.Authorities say one miner was rescued Monday.Rock burst accidents are often caused by fractures in rocks due to mining.This story is developing -- more updates to come. 632

NASHVILLE, Tenn. — A spokesman with Metro Nashville Police Department (MNPD) says unless changes are made to the city’s pandemic plan, there’s very little officers can do to enforce mandates at a private residence.The party, which caught the attention of Chad Boseman and his friend Andy, happened across the street from their house on Fern Ave. in East Nashville Saturday evening.“There was just tons of everything. Whatever you can think of a party, just times 20,” Andy said.They weren’t sure what they were seeing at first when people began lining up at the door. All they knew was they wanted to see for themselves. They walked over to find a party with what they say was easily more than 200 people.“I’m still recovering from this night,” Andy said.Promoted as the big unveiling for The Fashion House intended for photoshoots, people showed up to snap pics and even get tattoos.Boseman and company say they were there from 11 P.M. to 3 A.M. before MNPD officers arrived. Boseman says once people noticed cars were being towed, people began to leave.When approached by reporters, one of the homeowners declined to comment.Later in the day, one person claiming to be a homeowner posted a Facebook message saying he contacted police beforehand, and there were no violations. The homeowner ended the statement with “nothing illegal was done or the police would have stopped it.”MNPD said officers wrote citations for those parked illegally in neighboring driveways, but they did not write any citations related to the coronavirus mask mandate.Metro Nashville Public Health says it is investigating but won’t say what rules may have been broken.Not that any of the neighbors we talked to were too concerned. For them, it was something they couldn’t miss and likely won’t forget any time soon.“I mean there’s the usual risk that you take when you’re around a group of people, just like getting trampled or something. But I didn’t see any concerns really. I was just there to have a good time,” Andy said.This story was originally published by Levi Ismail on WTVF in Nashville. 2084

NASA's OSIRIS-REx mission and the asteroid Bennu have had a date planned for two years, and just after noon ET today, they finally got to meet face to face. OSIRIS-REx fired its thrusters for a small burn, putting it about 4.3 miles from Bennu, marking the end of its journey to the asteroid.The mission -- which stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer -- is NASA's first asteroid sample return mission. It launched in September 2016 and will spend two years up close and personal with Bennu. First images of the asteroid from the spacecraft's perspective have appeared as it got closer and closer.On Tuesday, the spacecraft will fly within 5 miles of Bennu, which will help design future orbits and map the surface.Over the next year, OSIRIS-REx will survey the asteroid using five scientific instruments on board the spacecraft. These instruments will help it determine a safe location from which to collect a small sample from Bennu's surface that will be returned to Earth in September 2023."Bennu's low gravity provides a unique challenge for the mission," said Rich Burns, OSIRIS-REx project manager at NASA's Goddard Space Flight Center. "At roughly 0.3 mile in diameter, Bennu will be the smallest object that any spacecraft has ever orbited."The sample from Bennu, a near-Earth asteroid, could help scientists understand not only more about asteroids that could impact Earth but about how planets formed and life began.OSIRIS-REx has a camera suite, a laser altimeter for 3D mapping, a thermal emission spectrometer to take temperature and mineral content and spectrometers to measure X-rays, nearly infrared and visible light.An arm mechanism called TAGSAM will reach out to collect the sample from Bennu's surface, making contact with the asteroid for five seconds in July 2020. During this contact, the arm will use a nitrogen gas burst to stir up rock and other materials on the surface so it can capture them. There is enough nitrogen for three attempts if the first is unsuccessful.NASA said the estimated 2.1-ounce sample size equates to about 30 sugar packets worth of dirt and rocks.The arm has a full range of motion, with joints capable of movement comparable to shoulder, elbow and wrist joints. It was "flexed" in space for the first time on November 14."The TAGSAM exercise is an important milestone, as the prime objective of the OSIRIS-REx mission is to return a sample of Bennu to Earth," said Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, Tucson. "This successful test shows that, when the time comes, TAGSAM is ready to reach out and tag the asteroid."In 2021, it will be time for the spacecraft to essentially turn around and begin its two-year journey home. The sample will be packed into a capsule that will drop in the Utah desert in 2023.For two years after the return, the sample will be cataloged and analyzed. Afterward, 75% of the returned sample will remain at NASA's Johnson Space Flight Center so it can be used for more research by scientists from around the world.Why did NASA select Bennu out of the 780,000 known asteroids in our solar system?It was discovered in 1999, and scientists have been studying it ever since. The asteroid fits a number of criteria that make it intriguing and convenient.Bennu is relatively close to Earth, and its orbit even crosses that of our planet, making a close approach every six years. Though small asteroids can rotate very quickly, Bennu has a diameter just a bit bigger than the height of the Empire State Building and rotates relatively slowly, each 4.3 hours. This means OSIRIS-REx can match its velocity and touch down briefly.The asteroid could pass close to Earth, closer than the moon, in 2135, with even closer approaches possible in 2175 and 2195. A direct hit is unlikely, but the data gathered during this mission can help determine the best ways to deflect near-Earth asteroids.The asteroid is also old and well-preserved, full of valuable materials that may even contain clues about how life began. Bennu is essentially a leftover from the formation of our solar system billions of years ago, although some of the minerals inside it could be even older.This carbon-rich asteroid could be full of organic molecules, metals, platinum and even water -- the essential ingredients for life. It's because of objects like Bennu that these resources were delivered to Earth during its formation.Asteroids could even serve as fuel stations for robotic and human missions if we can unlock the hydrogen and oxygen inside them, NASA said.Bennu probably broke off of a larger asteroid in the asteroid belt between Mars and Jupiter a couple billion years ago. This knocked it through space until an orbit close to Earth locked it in place. And Bennu is believed to be a grouping of rocks held together by gravity rather than a single object.But its orbit drifts 0.18 miles each year toward the sun, and OSIRIS-REx will enable researchers to understand why and to predict Bennu's movements. This could also explain how it ended up as a near-Earth asteroid."The story of this asteroid is the story of the solar system," said Bashar Rizk, instrument scientist for OSIRIS-REx. "When we understand Bennu, we will understand something fundamental about our solar system."The-CNN-Wire 5356

More people are interested in growing their own food and living a more sustainable life. That can be for people living off the grid or for people living in large cities."We are 50 by 126 ft. in the neighborhood of Ruby Hill," said Sharona Thompson.Less than five miles from downtown Denver, Colorado, nestled among standard city lots, sits Thompson’s urban homestead and the Ruby Hill Tiny Farm School."We grow tomatoes, squash. We’ve got pumpkins arching over, we’ve got chickens, we’ve got rabbits, we have bees, we have worms, and a cat that guards the whole school," said Thompson.Every inch of her yard is planned out to be the most beneficial and sustainable. She has two 55-gallon rain barrels that she uses to water the plants, and she also captures rainwater from her roof."We have it go down the gutter, into this little piping system. That goes under the ground, the sidewalk, under this bed and comes out to the tomatoes over here," said Thompson.Even the housing for her chickens has multiple uses. The coop catches rainwater which leads to a cherry tree. And, since the chickens are only 3-feet tall, she built a greenhouse on one side, allowing the chickens to roam underneath."With chickens, they give us eggs, but also they give us manure, and we can actually turn that manure into the soil and have more fertile soil," said Thompson.Thompson has been growing on her lot since she moved in nine years ago. She says especially now with COVID-19, more and more people are planting on their own land. She says seeds and plants are hard to come by."That’s a good sign to me. Sometimes we need a crisis to kind of wake us up to be active and to really see where some of our vulnerabilities are," said Thompson.She says while we’re not in a food emergency right now, she feels secure knowing she could live off her yield."If there was a food supply chain kink, for whatever reason, I know I can still go outside and get my food and know how to preserve it," said Thompson.But there’s also a sense of pride in her tiny farm by doing something our ancestors did many generations ago."When I go out here, and I see the plants growing and changing from winter to the end of summer, I feel so satisfied on a deeper level that I know how to do this," said Thompson.Through her tiny farm school, she teaches kids and adults how to start and build their own urban homestead."When I bring students here and they learn, it’s beautiful. They are like, 'I want to do something like this.' I’ve had several people say that they want to start schools too to share this information. It’s empowering," said Thompson. 2619

MLB and the MLBPA jointly announced on Friday that 31 players tested positive for COVID-19 this week amid the first round of tests as players resume training ahead of this year’s shortened season.Teams began working out this week at ballparks across the US as the coronavirus-shortened season is slated to get underway in three weeks. As part of MLB’s plan to resume, players and support staff will be frequently tested for the virus.But MLB is unique insofar that other major team sports in the US are planning on resuming play in hub cities instead of traveling from city to city. Both the MLS and NBA will play out of Orlando, Florida, while the NHL will resume in the near future at two yet-to-be determined hubs..All told, MLB said it conducted 3,185 samples, with 1.2% coming back positive. In addition to 31 players testing positive, seven staff members also had a positive COVID-19 result.Nineteen of MLB’s 30 teams had at least one player or staff member test positive for the virus 999
