California's Joshua Tree National Park on Wednesday will become the latest casualty of the federal government's partial shutdown, closing campgrounds due to health and safety concerns over near-capacity pit toilets.With a quarter of the federal government employee workforce beginning 2019 out of work or working without a paycheck, agencies from the National Park Service to the Environmental Protection Agency and the Smithsonian museums are feeling the pinch.Unlike some previous government shutdowns, when national parks closed entirely, gates have remained opened under the Trump administration, leaving parks severely understaffed.Joshua Tree, more than 792,000 acres of national park nestled between Palm Springs to the south and the town of Joshua Tree to the north, will remain open during the shutdown but its popular campgrounds will close at noon Wednesday, according to the National Park Service."The park is being forced to take this action for health and safety concerns as vault toilets reach capacity," the park service said."In addition to human waste in public areas, driving off-road and other infractions that damage the resource are becoming a problem."The National Park Service also said the shutdown prevented it from making staff available to "provide guidance, assistance, maintenance, or emergency response.""Any entry onto NPS property during this period of federal government shutdown is at the visitor's sole risk," the park service said this week.Trash collection has stopped along with road and walkway maintenance.Rattlesnake Canyon will close to reduce the number of search and rescue events for rangers already spread thin because of the shutdown, the park service said.The shutdown has also left a stinking mess at Yosemite National Park in the Sierra Nevada mountain range in eastern California.Yosemite, the nation's third most-visited national park, remains open but various campgrounds as well as snow play areas are "closed due to human waste issues and lack of staffing," according to its website.On the Yosemite Twitter account on Sunday, officials said a "lack of the restrooms and resulting impacts from human waste" forced the closure of the campgrounds. "People entering closed areas are being cited," the tweet said.The visitor center and museum at Yosemite are closed and emergency response times may increase during the shutdown.Kristen Brengel, vice president of government affairs for the National Parks Conservation Association, said the shutdown not only hurts the parks but also surrounding communities that rely on an estimated million a day from tourism."It's really a big deal for Joshua Tree," she said of the campground closings. "This is a very popular season for people that come there."Brengel said staff shortages had created a sense of "lawlessness" in the parks."People are bringing in dogs and drones and there are instances where people aren't following the rules and it is not good for the wildlife and the environment," she said.Joshua Tree Superintendent David Smith, in a statement, thanked the "local businesses, volunteer groups, and tribal members" who have stepped up to collect trash and maintain grounds during the shutdown."This is a reflection on their efforts and the park is very fortunate to have a community that exhibits the kind of care and concern witnessed over the last week," he said.David Lamfrom, director of the California Desert and National Wildlife Programs of the National Parks Conservation Association, said the volunteer efforts can't supplant the work of the park service."People are walking off trails, bringing their dogs," he said. "People are trampling and destroying the things they want to preserve without knowing it. ... People are camping where they want or showing up really early or late at certain watering holes so animals like bighorn sheep won't come down to drink."Key parts of the federal government have been impacted by the December 22 shutdown, including the departments of Homeland Security, Justice, Interior, State and Housing and Urban Development.The shutdown began after President Donald Trump was unwilling to back down from his demand for billion for his long-promised border wall. The figure was a nonstarter for Democrats, leaving Congress at an impasse. 4336

Astronomers have detected the most massive neutron star ever, and it almost shouldn't even exist.Neutron stars are the smallest in the universe, with a diameter comparable to the size of a city like Chicago or Atlanta. They are the leftover remnants of supernovae. But they are incredibly dense, with masses bigger than that of our sun. So think of the sun, compressed into a major city.In the case of the newly detected neutron star, dubbed J0740+6620, it's 333,000 times the mass of the Earth and 2.17 times the mass of the sun. But the star is only about 15 miles across. It's 4,600 light-years from Earth.This is close to the limit of how much mass a compact object can contain before it crushes itself into a black hole.The neutron star itself is rapidly spinning, which is called a pulsar because they send out beams of radio waves from each magnetic pole. The beams mimic the sweeping motion of a lighthouse beam, hence the name "pulsar."Pulsars act like atomic clocks because they regularly pulse, so astronomers can use them to study space and time.The star was detected by the 1098

An intense and sprawling winter storm is expected to develop starting Tuesday across the Great Plains, delivering hurricane-force wind gusts, severe rain, heavy snow and floods for days across a wide swath of the central United States.The storm is forecast to rapidly intensify overnight east of the Colorado Rockies. It will then trek slowly northeast through Thursday, delivering a variety of extreme weather from New Mexico to the Midwest.Centered in Kansas as it hits its midweek peak, gusts as strong as 100 mph are possible as the storm toys with a state record low for sea level pressure, which is one indicator of storm strength.A white-out is expected in parts of the northern PlainsBlizzard and winter storm warnings are in place for portions of Colorado, Wyoming, Nebraska and South Dakota.Heavy snow is expected in portions of the Rockies and northern Plains, with a foot or more falling in many areas.Strong winds will bring white-out conditions through Wednesday evening to places including western Nebraska and northeast Colorado. Blowing snow will make travel treacherous or impossible during these times.Snow should taper off by midday Thursday, but strong winds will persist through the evening.Hurricane-like gusts may whip the southern PlainsThunderstorms overnight Tuesday across portions of the southern Plains will make way on Wednesday for sustained winds of 35 to 45 mph, akin to the strength of a low-end tropical storm. The National Weather Service has issued high wind watches for more than 8 million people.Even stronger wind gusts of 50 to 70 mph are expected Wednesday afternoon through Thursday morning across Colorado, New Mexico, Texas and Oklahoma, CNN meteorologist Monica Garrett said. Some areas could see gusts as strong as 100 mph, which is equivalent to the wind speed of a Category 2 hurricane.Widespread power outages will be a significant concern.Soaking rains and snowmelt could flood the MidwestParts of the Midwest on Wednesday are expected to see heavy rains, a big worry after recent record-setting snowfall.Flood watches have been issued across the Midwest and Great Plains amid concerns that heavy rains will melt snowpack and trigger significant flooding. Flash flooding is possible if ice jams clog rivers and streams, the weather service notes.Rain is predicted to begin turning to snow in these areas by Wednesday evening.More severe storms are due to hit the SouthFarther south, strong winds, large hail and a few tornadoes are possible overnight Tuesday from southeastern New Mexico to western Texas.As the system pushes east, another round of early spring storms is due to take shape. The primary concern is damaging winds, and brief tornado activity is possible.Portions of Louisiana and Arkansas face a slight risk for severe weather Wednesday, the Storm Prediction Center said. The risk shifts Thursday into Mississippi, Tennessee and Alabama. 2917
