General Motors’ self-driving car company will attempt to deliver on its long-running promise to provide a more environmentally friendly ride-hailing service in an unorthodox vehicle designed to eliminate the need for human operators to transport people around crowded cities.The service still being developed by GM’s Cruise subsidiary will rely on a boxy, electric-powered vehicle called “Origin” that was unveiled late Tuesday in San Francisco amid much fanfare. It looks like a cross between a mini-van and sports utility vehicle with one huge exception — it won’t have any steering wheel or brakes. The Origin will accommodate up to four passengers at a time, although a single customer will be able summon it for a ride just as people already can ask for a car with a human behind the wheel from Uber or Lyft.For all the hype surrounding the Origin’s unveiling, Cruise omitted some key details, including when its ride-hailing service will be available and how many of the vehicles will be in its fleet. The company indicated it will initially only be available in San Francisco, where Cruise has already been offering a ride-hailing service that’s only available to its roughly 1,000 employees.By eliminating the need for a human to drive, Cruise theoretically will be able to offer a less expensive way to get around — a goal already being pursued by self-driving car pioneer Waymo, a Google spinoff that has been testing robotaxis in the Phoenix area for nearly three years.Cruise had planned to have a robotaxi service consisting of Chevrolet Bolts working without human backup drivers by the end of 2019, but moved away from that last year after one of Uber’s autonomous test vehicles ran down and killed a pedestrian in the Phoenix suburb of Tempe, Arizona, during 2018.Still aware of the fallout from that deadly crash, Cruise is promising “superhuman performance” from the Cruise, which GM hopes to manufacture at half the price of comparable vehicles using fuel-combustion engines. GM also expects to announce where the Origin will be made within the next few weeks, Cruise CEO Dan Amman said.The Origin won’t be sold to consumers though. “It is not a product you can buy, but an experience you share,” Amman said.The Origin represents another significant step for Cruise, which had only 40 employees when GM bought it in 2016 as part of its effort to catch up in the race to build cars that can drive themselves. Since then, Cruise has attracted more than billion from investors, including .75 billion from Honda and .25 billion from Japanese tech investment firm SoftBank. Honda also helped develop the Origin. GM currently values Cruise at billion, fueling speculation that the subsidiary may eventually be spun off as a publicly traded company.Whenever Cruise’s ride-hailing service makes its debut, it will still be chasing Waymo, whose work on self-driving car technology began inside of Google more than a decade ago. Waymo’s Phoenix-area service already has given more than 100,000 rides, according to the company. It expanded beyond the test phase service 13 months ago with a ride-hailing app that now has about 1,500 active monthly riders, Waymo says.By comparison, ride-hailing leader Uber now boasts about 103 million active monthly users with a service that relies on human drivers — a dependence that is the main reason the company has been losing money throughout its history. Despite the fatal 2018 crash that stoked the public’s worst fears about self-driving cars, Uber is still trying to build a fleet of robotic taxis as part of its question to become profitable.Tesla CEO Elon Musk has also pledged that his company’s electric cars will be able to drive themselves without a human behind the wheel before the end of this year so they can moonlight as taxis when their owners don’t need the vehicles, but industry analysts doubt that promise will come to fruition. 3921

If President Donald Trump invokes a "national emergency" at the US border and uses emergency powers to bypass Congress and obtain funding to build his long-promised border wall, a battle in the courts over the questionable legality of spending those dollars would be virtually guaranteed.But the United States is no stranger to national emergencies.In fact, the US has been in a perpetual state of declared national emergency for four decades, and the country is currently under 31 concurrent states of emergency about a spectrum of international issues around the globe, according to a CNN review of documents from the Congressional Research Service and the Federal Register.The federal government is well into its third week of a partial shutdown over funding for the President's wall along the border with Mexico. The White House and Democrats in Congress are locked at an impasse: Trump is demanding .6 billion, while House Democrats have vowed not to give him a dollar."I may declare a national emergency dependent on what's going to happen over the next few days," Trump told reporters on Sunday morning, floating using the National Emergencies Act of 1974 to activate special power during a crisis.House Intelligence Committee chairman Adam Schiff told CNN's Jake Tapper on "State of the Union" that Trump doesn't have the authority to do so. "If Harry Truman couldn't nationalize the steel industry during wartime, this President doesn't have the power to declare an emergency and build a multibillion-dollar wall on the border. So, that's a nonstarter."But acting White House chief of staff Mick Mulvaney defended the possibility: "I'm actually heavily involved with it and have been working with all of the Cabinet secretaries to try and find money that we can legally use to defend the southern border," he said on the same program. "Presidents have authority to defend the nation."Not all national emergency declarations are so controversial. Trump has already issued three national emergency declarations during his tenure, most prominently a national emergency meant to punish foreign actors who interfere in American elections, though the move garnered bipartisan criticism for not going far enough. He's also invoked emergency powers to slap sanctions on human rights abusers around the globe and on members of the Nicaraguan government amid corruption and violent protests there.Here's a full list of the 31 active national emergencies under the National Emergencies Act, dating back to the Carter administration:1.

How does something like an x-ray become the bill that comes in the mail?It's the product of medical billing, a decades-old process that technology has recently transformed.It starts when someone gets hurt or sick and goes to the clinic or hospital. They fill out paperwork and see the doctor. Once the visit is over, administrators ship off insurance and visit details for processing.Behind the scenes, medical coders assign each service a code. Those can include diagnoses, procedures, and treatments. These codes help determine how much the insurance company will cover.They create a detailed, itemized list of services, medical codes, and co-payments and send it to medical billers.The billers use the list to create what’s called a claim for insurance companies to consider.Insurance companies can do one of three things.· Accept the claim.· Deny it and ask for corrections.· Or, reject it entirely.There are a lot of variables that go into how much insurance pays. Whatever the company doesn’t cover ends up in a bill in the mail.The process is digital now and much faster than doing everything by hand. It also reduces the risk of human error, which could save Americans money. 1195

I stand with Uber and Lyft drivers striking in LA. One job should be enough to make a decent living in America, especially for those working for multibillion-dollar companies. Drivers must be paid the wages they deserve. #StrikeUberLyft https://t.co/uyp8E0VkyR— Bernie Sanders (@BernieSanders) March 25, 2019 320
