Tesla is disputing claims by a California man that all three models of the company’s cars can suddenly speed up on their own without the driver touching the accelerator pedal.Tesla said Monday it checks when drivers report that their car accelerated on its own, and in every case where the company has the car’s data, it drove as designed.The company also claimed the man who filed a petition with federal safety officials is a short-seller of Tesla shares, referring to investors who borrow shares in a company’s stock and try to profit by replacing them after the share price falls.On Friday, the National Highway Traffic Safety Administration said it would look into a petition filed by Brian Sparks of Berkeley, California, and decide whether to open a formal investigation. Sparks’ allegations cover about 500,000 Teslas, including Model 3, Model S and Model X vehicles in model years 2013 through 2019.Sparks said Tesla owners have lodged 127 complaints with the government, covering 110 crashes and 52 injuries.Tesla, which did not respond when asked for comment on Friday, posted a statement Monday saying its electric vehicles do not accelerate on their own.The company called the petition “completely false,” adding that “the car accelerates if, and only if, the driver told it to do so, and it slows or stops when the driver applies the brake.”Sparks said in his 69-page petition that many of the Tesla accidents happened during parking, that the complaint rate was much higher than for other vehicles, and that Tesla refused to share the car’s data with owners after incidents.The highway agency has yet to verify the complaints. The people who filed complaints were not identified in NHTSA’s database. 1726

The first participant in a clinical trial for a vaccine to protect against the new coronavirus will receive an experimental dose on Monday, according to a government official.The National Institutes of Health is funding the trial, which is taking place at the Kaiser Permanente Washington Health Research Institute in Seattle. The official who disclosed plans for the first participant spoke on condition of anonymity because the move has not been publicly announced.Public health officials say it will take a year to 18 months to fully validate any potential vaccine. Testing will begin with 45 young, healthy volunteers with different doses of shots co-developed by NIH and Moderna Inc. There’s no chance participants could get infected from the shots, because they don’t contain the virus itself. The goal is purely to check that the vaccines show no worrisome side effects, setting the stage for larger tests.Dozens of research groups around the world are racing to create a vaccine as COVID-19 cases continue to grow. Importantly, they’re pursuing different types of vaccines — shots developed from new technologies that not only are faster to produce than traditional inoculations but might prove more potent. Some researchers even aim for temporary vaccines, such as shots that might guard people’s health a month or two at a time while longer-lasting protection is developed.Also in the works: Inovio Pharmaceuticals aims to begin safety tests of its vaccine candidate next month in a few dozen volunteers at the University of Pennsylvania and a testing center in Kansas City, Missouri, followed by a similar study in China and South Korea.Even if initial safety tests go well, “you’re talking about a year to a year and a half” before any vaccine could be ready for widespread use, according to Dr. Anthony Fauci, director of NIH’s National Institute of Allergy and Infectious Diseases.That still would be a record-setting pace. But manufacturers know the wait — required because it takes additional studies of thousands of people to tell if a vaccine truly protects and does no harm — is hard for a frightened public.President Donald Trump has been pushing for swift action on a vaccine, saying in recent days that the work is “moving along very quickly” and he hopes to see a vaccine “relatively soon.”Today, there are no proven treatments. In China, scientists have been testing a combination of HIV drugs against the new coronavirus, as well as an experimental drug named remdesivir that was in development to fight Ebola. In the U.S., the University of Nebraska Medical Center also began testing remdesivir in some Americans who were found to have COVID-19 after being evacuated from a cruise ship in Japan.For most people, the new coronavirus causes only mild or moderate symptoms, such as fever and cough. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia. The worldwide outbreak has sickened more than 156,000 people and left more than 5,800 dead. The death toll in the United States is more than 50, while infections neared 3,000 across 49 states and the District of Columbia. The vast majority of people recover. According to the World Health Organization, people with mild illness recover in about two weeks, while those with more severe illness may take three weeks to six weeks to recover.___The Associated Press receives support for health and science coverage from the Howard Hughes Medical Institute’s Department of Science Education.

The global death toll from the coronavirus has now topped 2,000, but that’s little compared to the flu. In the U.S. alone this season the CDC estimates at least 14,000 flu-related deaths. Still, the fear of coronavirus may be spreading faster than the virus itself. Quarantines, lockdowns and daily death toll updates have heightened the fear of the respiratory illness.Much of it stems from the unknown. The exact mortality rate is still a big question says Dr. Emily Landon, an epidemiologist and infectious disease specialist at the University of Chicago Hospital. “If you just have a cold you just stay home, and you never get tested. And so those people don't appear in the totals which make it look like it might be more deadly than it is” she says. Dr. Landon says the virus is causing alarm for several reasons: Everyone is susceptible, there is no vaccine yet and it’s unclear whether antiviral medicines will be effective. “More people that get this new coronavirus, it looks like more of them will die than the same number of people who get the influenza virus,” says Landon. Social media misinformation, like a global air travel map that went viral – incorrectly predicting the spread of the outbreak, have not helped. “Fear has driven the Chinese response to the crisis,” says Phillip Braun, a clinical professor of finance and Northwestern University’s Kellogg School of Management.That fear-factor he says is costing global financial markets“For China it is going to be billions for the U.S. it's unclear yet,” explains Braun.Suspended flights, supply chain disruptions and factory and store closures are already hurting major U.S. companies like Wal-Mart, Starbucks and Apple. “Apple's already announced their earnings are going to be reduced because their factories in China are shut down so they're not going to have enough supply of Apple iPhones here in the states,” says Braun.Still, public health officials like Dr. Landon are quick to point out that they are being vigilant about identifying cases, quarantining and in turn isolating the virus so it can’t reproduce.“The only thing that's really going to protect you is if you clean your hands before you touch your face. Period,” she says.Economists and healthcare experts agree that while there is cause for concern so far, there is not yet reason to panic. 2346

The body of a missing Texas police chief who fell overboard while on a fishing boat was recovered Sunday morning, the US Coast Guard said.Kemah Police Chief Chris Reed was on the boat with his wife in Galveston Bay on Friday afternoon when it was hit by a wake of a passing vessel.His body was found about 8 a.m. a mile and a half north of the Texas City Dike in Texas City, the Coast Guard said.Reed's wife remained on the boat and was not injured. He was not wearing a life jacket at the time, Coast Guard Lt. Cmdr. Caren Damon told reporters.Kemah is on Galveston Bay about 40 miles from Houston.Coast Guard crews searched more than 650 square miles over some 40 hours.About 40 vessels, including 15 from the Coast Guard, searched, the Coast Guard said. An aircrew and a team of drones -- along with 12 state, local and federal agencies -- were involved, said Tom Munoz, emergency management coordinator for Texas City."Number one, he's just a great cop, just to start off with. He's been in this county a long time, working for several different agencies," said Texas City Police Chief Joe Stanton before the body was located. "We're a tight-knit group. He's one of ours. And, we're out there and we're gonna find him."In addition to his career as a police officer, Reed was a retired Army paratrooper and was on the Clear Creek Independent School District board, according to CNN affiliate 1407
