NEW YORK (AP) — Uber shares sunk even further after its disappointing stock market debut as doubts lingered over the company's ability to turn a profit and trade tensions dragged down the overall market.The ride-hailing giant's stock fell 10% and hovered around Monday afternoon on Uber's first full day of trading.The mounting losses followed Uber's disappointing initial public offering. On Friday, it took a 7 million hit — the largest loss on the first day of trading by a U.S.-based company in recent history, according to Renaissance Capital.Uber's earliest investors are still making money off the IPO, but "for late-round investors, it's possible by the time they exit they will end up with a loss," said Jay Ritter, finance professor at the University of South Florida.Among the recent big investors — and perhaps losers — is PayPal, which had disclosed plans to buy 0 million in Uber stock at the IPO price of .Uber has had no trouble convincing venture capitalists to pour money into its earlier funding rounds, but with its unclear path to profitability, it's having a more difficult time with Wall Street investors."It's clearly a high-risk, high-reward scenario. You're betting on something that may happen 10 years down the road," said Matt Kennedy, senior IPO market strategist at Renaissance Capital, a manager of IPO exchange traded funds. "Public investors are looking at profits and not seeing any, and the company's growth in the last quarter was relatively strong, but I don't think it blew anyone away."Uber's main U.S. rival, Lyft, is in a similar spiral. Its stock was trading below on Friday, down 33% from its IPO price of .It's rare to see shares in a tech company hit so hard upon going public. Over the past five years, just 10% of similar companies finished their first day of trading below their IPO price, Kennedy said.Uber's revenue last year surged 42% to .3 billion, but the company admits it could be years before it turns a profit. 2000

New research may be hard for some dog owners to accept; the study found that dogs do not understand every word a human says to them.The researchers say dogs cannot hear subtle differences between words the way humans can. For example, the difference between “dog” and “dig” sounds different to human ears, but not so different to dog ears.The researchers came to their conclusion after measuring brain activity of family dogs by taping electrodes to the animals’ heads. They then played recordings of instruction words they knew, like “sit,” then similar-sounding nonsense words, like “sut,” and finally an unrelated nonsense word or sound, like “bep.”The dogs in the study, who were not trained ahead of the study, could quickly tell the difference between the instruction words and the unrelated nonsense words."The brain activity is different when they listen to the instructions, which they know, and to the very different nonsense words, which means that dogs recognize these words," lead study author and postdoctoral researcher at E?tv?s Loránd University in Budapest, Lilla Magyari told CNN.So, the good news is, yes, dogs are listening to human words and understanding some.However, brain activity showed a similar reaction in the dogs between the instruction word and the similar nonsense word.Dogs are renowned for their auditory capacity and ability to hear words and sounds, however the results show they may not be able to distinguish between subtle speech sound differences.Magyari says more research is needed to understand why this is."They may just not realize that all details, the speech sounds, are really important in human speech. If you think of a normal dog: That dog is able to learn only a few instructions in its life," she told CNN.The study was published this week in the Royal Society Open Science journal. 1845

NEW YORK (AP) — U.S. health officials are dropping a controversial piece of coronavirus guidance and telling all those who have been in close contact with infected people to get tested.The Centers for Disease Control and Prevention (CDC) essentially returned to its previous guidance about such tests."Due to the significance of asymptomatic and pre-symptomatic transmission, this guidance further reinforces the need to test asymptomatic persons, including close contacts of a person with documented SARS-CoV-2 infection," the CDC wrote in a "clarification" posted Friday. With the change, the CDC got rid of language posted last month that said people who didn’t feel sick didn’t need to get tested.That August change set off a rash of criticism from health experts who couldn’t fathom why the nation’s top public health agency would say such a thing amid a pandemic that has been difficult to control.The New York Times reports that last month's change was not actually written by CDC scientists and was posted to the agency’s website despite their serious objections. It reportedly came from the Department of Health and Human Services.The CDC website now says testing is recommended for all close contacts of persons with SARS-CoV-2 infection. "Because of the potential for asymptomatic and pre-symptomatic transmission, it is important that contacts of individuals with SARS-CoV-2 infection be quickly identified and tested," the agency writes. 1458

NOANK, Ct. -- As a humid summer breeze blew across the bow of the oyster boat Marc Harrell was standing on, he looked out toward Long Island Sound and could see some signs that the nation’s economy is recovering.Harrell has spent most of his life fishing those waters for oysters under the guidance of Captain Jim Markow, both men are the backbone of Mystic Oysters, a family owned business that’s been around for decades.“Our business hasn’t completely rebounded yet, it’s still going to be some time before it does,” Harrell said as he dropped an oyster dredge off the side of the boat.In Noank, Connecticut, the headwaters of the Atlantic Ocean come crashing into the Mystic River. The combination of saltwater and fresh water creates what most in the coastal community say are some of the best oysters in the world.But the coronavirus outbreak has been threatening a way of life that’s been a part of this community for generations. It’s a pandemic impacting both land and sea.“We don’t know what’s going to happen and we’re still not 100% optimistic that everything is going to be the same once this is all done,” Markow said.For the better part of 40 years, Markow has operated Mystic Oysters. The small family-owned company prides itself on harvesting oysters directly from their own oyster beds and shipping them directly to restaurants and suppliers up and down the East Coast. But as countless restaurants closed because of the coronavirus, Mystic Oysters no longer had a customer base.Like so many other small businesses across the country, COVID-19 has forced Mystic Oysters to reinvent themselves. The company has started selling directly to consumers, harnessing social media and word-of-mouth to bring customers directly to the docks to buy oysters as fresh as they come. They’ve even started coordinating with other small businesses and fisherman to hold farmers’ markets and pop-up sales tents around the area.Revenue is still down considerably but Markow sees a future in their new business model.“It’s exciting to see the opportunities that are out there that we weren’t aware of,” he said. “We were forced into a situation to reinvent our business and I think in the long run it’ll be a positive, in the short run though, definitely scary.”Experts say that kind of ingenuity and creativity is something other small businesses can emulate as they try to navigate the uncertainty surrounding the virus.“That’s always been the staple of small business, finding those market opportunities and working with the resources they have to survive,” said Holly Wade, who serves as a researcher with the National Federation of Independent Businesses.As for Mystic Oysters, they see diversification as a way forward. For the first time in the company’s history they’ve even started selling fresh lobsters directly to consumers. Markow hopes other small business owners who might be struggling see what they’re doing here and find hope for a future rebound.“Don’t give up, keep thinking. There’s a lot of opportunities out there if you want to be creative.” 3071
