Trade war fears are rattling Wall Street as President Trump prepares a crackdown on China.The Dow dropped 724 points when the Dow closed on Thursday, underlining growing concerns among investors about looming tariffs on China."A global trade war, whether it's real or perceived, is what's weighing on the market," said Ian Winer, head of equities at Wedbush Securities. "There's this huge uncertainty now. If China decides to get tough on agriculture or anything else, that will really spook people." 513

This year, more than half of all U.S. states have had confirmed or possible cases of acute flaccid myelitis, the polio-like illness that can cause paralysis and mostly affects children, according to an exclusive CNN analysis.CNN reached out to health departments in every state; 48 states responded, plus the District of Columbia. Of those, 30 states said they had cases that were confirmed, suspected or being investigated -- including 15 states that said they had confirmed cases in 2018.In total, CNN found 47 confirmed cases and 49 more that were suspected or being investigated, for a total of 96.The U.S. Centers for Disease Control and Prevention, which releases only confirmed numbers, says 16 states had 38 cases as of September 30. It does not identify the states. 782

Thursday marks exactly six months since the World Health Organization (WHO) declared a global health crisis connected with the disease that was then simply known as the novel coronavirus.Half a year later, the virus has infected 17 million people on every continent and killed more than 600,000 worldwide.On Jan. 31, WHO issued a statement saying that Dr. Tedros Adhanom, the director-general of the organization, had accepted a committee's recommendation to declare the outbreak of the virus in China a "public health emergency of international concern."At the time, the outbreak was mainly concentrated in China, as the country had confirmed 7,711 cases of the virus and 170 deaths linked to the disease. While the virus had been recorded in five other countries — including five cases in the U.S. — there had been no deaths recorded outside of China.In its Jan. 31 declarations, the WHO did not recommend any travel or trade restrictions, but urged countries to prepare for containment and "place emphasis on reducing human infection, prevention of secondary transmission and international spread."The organization issued its recommendation 10 days after China reported that the virus appeared to be spreading from person-to-person, a finding that indicated the disease could have far-reaching implications. The New York Times reports that by that time, thousands had traveled out of Wuhan, the virus' place of origin, possibly spreading it around the world. China has since faced criticism for not reporting its findings sooner.That same day, President Donald Trump took action to block entry into the U.S. of any person that had been in China for the last 14 days. The order did not apply to U.S. citizens. While the move may have temporarily delayed the virus' widespread arrival, his administration's inaction for the next month would prove costly.During the next month, the CDC would face significant delays in developing a test for COVID-19, which would cause a testing backup in the months to come. The president also repeatedly downplayed the severity of the situation, declaring on Feb. 26 that the number of cases in the U.S. would go down to zero in the coming days.In the months since the WHO's declaration, 150,000 Americans have died of COVID-19, and more than 4 million have been infected. Both figures are by far the most of any other country. 2370

There is a lot of concern along the Gulf Coast right now. Two tropical systems are headed for the area at the same time, potentially impacting land on the same day.It's very rare according to the National Weather Service (NWS), something we haven't seen in decades.What's most concerning, is the amount of people in the path of the storms.“The number of people that could be impacted by these two systems is huge, you know, from the northern part of Texas, throughout the entire coast of west side of Florida and the panhandle as well,” said Joel Cline, a meteorologist and NWS Tropical Program Coordinator.Large amounts of rain, storm surge and wind are threatening the Gulf Coast early next week.So, could these systems merge? It's something called the Fujiwhara effect. It's named after a Japanese meteorologist who first described the effect. It's something that happens in the pacific with typhoons.“That’s where two come in close contact and then they move around each other counterclockwise,” said Cline. “That's not going to happen in this one.”There is another potential impact of these systems being close to each other.“So, when you have two of these in one area, then the descending air may get into the other one and help weaken it or make the other one stronger,” said Cline.There's still a lot of time for things to change. Regardless, meteorologists say people in the paths of these storms need to be hurricane ready.“Labor Day is essentially the halfway point and so we've got a lot more hurricane season left and what we’ve already been through,” said Cline. 1584

TOKYO (AP) -- The decades-old dream of zipping around in the sky as simply as driving on highways may be becoming less illusory.Japan's SkyDrive Inc., among the myriads of "flying car" projects around the world, has carried out a successful though modest test flight with one person aboard.In a video shown to reporters on Friday, a contraption that looked like a slick motorcycle with propellers lifted several feet (1-2 meters) off the ground and hovered in a netted area for four minutes.Tomohiro Fukuzawa, who heads the effort, said he hopes to turn it into a real-life product by 2023, but acknowledged that making the vehicle safe was critical. 658
