Washington is on the brink of a partial government shutdown, with funding set to expire for several key federal agencies at midnight on Friday and no guarantee that lawmakers can come up with a plan that President Donald Trump will support to extend the rapidly approaching deadline.For now, it looks like the President is unwilling to back down from his demand for 378

Uranium ore stored at the Grand Canyon National Park museum may have exposed visitors and workers to elevated levels of radiation, according to the park's safety, health and wellness manager.Elston Stephenson told CNN that he began asking officials from the National Park Service and Department of the Interior last summer to warn workers and tourists they had possibly been exposed to unsafe levels of radiation. After his requests were ignored, he said he sent an email to all park staff at the Grand Canyon on February 4."If you were in the Museum Collections Building (bldg 2C) between the year 2000 and June 18, 2018, you were 'exposed' to uranium by OSHA's definition," said the email, which Stephenson provided to CNN."Please understand, this doesn't mean that you're somehow contaminated, or that you are going to have health issues. It merely means essentially that there was uranium on the site and you were in its presence. ... And by law we are supposed to tell you."The National Park Service is investigating what happened and working with the Occupational Safety and Health Administration and the Arizona Department of Health Services, according to the Department of the Interior, which oversees the park service."Uranium naturally occurs in the rocks of Grand Canyon National Park. A recent survey of the Grand Canyon National Park's museum collection facility found radiation levels at 'background' levels -- the amount always present in the environment -- and below levels of concern for public health and safety. There is no current risk to the public or Park employees," the department said in a statement provided to CNN. The National Park Service also said there is "no current risk" to the public or park employees."The museum collection facility is open and employee work routines have continued as normal," Emily Davis, spokeswoman for the Grand Canyon National Park, said in a statement. "The NPS takes public and employee safety and the response to allegations seriously. We will share additional information about this matter as the investigation continues."Stephenson told CNN that in early June he found out about three 5-gallon buckets of uranium ore that had been stored next to a taxidermy exhibit at the park's museum for nearly two decades. He said he immediately contacted a park service radiation specialist to report the danger.According to a report from a park service radiation safety officer who responded to Stephenson's request on June 14, 2018, testing results were positive for radioactivity above background levels near the buckets, but elsewhere the radiation levels were not elevated.Still, according to the report, the park service decided to remove the buckets on June 18 and dispose of the contents in the nearby Lost Orphan uranium mine, where the ore had come from.Stephenson told CNN that park service workers were inadequately prepared to handle the radioactive material, moving the buckets wearing gardening gloves purchased at a general store, and using mop handles to lift the buckets into pickups for transport.Stephenson said that after trying and failing for months to get National Park Service officials to inform employees and the public about the possible uranium exposure, he filed a complaint with OSHA in November.The next day, Stephenson said, OSHA sent inspectors in protective suits to check the museum and found that park service workers brought the buckets back to the park facility after dumping the uranium ore."OSHA has an open investigation on the issue that was initiated on November 28," OSHA spokesman Leo Kay said in statement to CNN, declining to comment further on an active investigation.Staff for US Rep. Tom O'Halleran, D-Arizona, met with Stephenson in December, according to Cody Uhing, the congressman's communications director."We flagged this to the Natural Resources Committee, which is responsible for oversight for that area. They and we have requested the Department of the Interior's Office of the Inspector General to look into it and provide us with a report," Uhing said.The Department of the Interior's Office of the Inspector General confirmed Tuesday that it had received a letter from O'Halleran and that it would review it.Anna Erickson, associate professor of nuclear and radiological engineering at Georgia Tech, said the uranium exposure at the museum is unlikely to have been hazardous to visitors."Uranium ore contains natural (unenriched) uranium which emits relatively low amounts of radiation," Erickson said. "Given the extremely low reading (zero above background) 5 feet away from the bucket, I'm skeptical there could be any health hazards associated with visiting the exhibit."Stephenson told CNN that tours of schoolchildren often walked by the buckets at the museum, but his larger concern was for park employees and high school interns working near the uranium every day."A safe workplace really is a human right," he said. 4984

Twitter is considering labeling tweets that violate its rules but should remain on the platform because they're in the public interest.Vijaya Gadde, Twitter's head of legal, policy and trust made the announcement during an on-stage 244

WASHINGTON, D.C. – U.S. Rep. Matt Gaetz is under self-quarantine after coming in contact with a person at a conference who tested positive for COVID-19, the disease caused by the new coronavirus. The Florida congressman’s team made the announcement on Twitter Monday, 11 days after coming in contact with the infected person at the Conservative Political Action Conference (CPAC). Congressman Gaetz was informed today that he came into contact with a CPAC attendee 11 days ago who tested positive for COVID-19.— Rep. Matt Gaetz (@RepMattGaetz) 556

Warmer weather means tick season across the U.S., and a number of tick-borne disease cases has increased over the past few years.“Lyme disease is gonna be the most common disease we see,” said Nicole Chinnici, laboratory director of the Dr. Jane Huffman Wildlife Genetics Institute. Chinnici is part of the Pennsylvania Tick Research Lab.“Tick season generally starts in the spring. It’s as we're coming out of winter and getting into the warmer months,” explained Dr. Mark Montano, the medical director of CareNow Urgent Cares in Colorado.The CDC said disease cases from mosquito, tick, and flea bites more than tripled from 2004 to 2016 in the U.S.. They predict the number of infections in any given season is complicated, but to put it in perspective, the number of tick-borne disease cases increased from 48,610 reported cases in 2016 to 59,349 reported cases in 2017. “There’s a lot of factors in it,” Chinnici said. She said reasons could include how mild the winter was, how long the warmer months are, and even animal hunting and population control. Another factor is how much time people spend outside.“People are free right now. They're working from home, so they are spending more time outdoors, so that's putting them at a greater risk just because of everything else going on with COVID-19,” Chinnici said.The tick research lab is one of only a few in the U.S. “We receive ticks from people, physicians, and then we test them in the lab using molecular techniques, and then we report the results back to the customer within 72 hours,” she explained.All you have to do is send it in. For Pennsylvania residents, it’s free. For cases in other parts of the U.S., there is a fee that comes with the lab test.“We’re providing the individual that was exposed to the tick bite with early detection of whether or not they've been exposed to a tick-borne disease,” Chinnici said.A quick look at their 1918
