As scientists learn more about COVID-19, they are realizing that how people react to the virus could be based on the body's response to viruses like common colds.Meharry Medical College President Dr. James Hildreth says some studies are showing some individuals have T-cell responses to COVID-19 even though they never been exposed to it.He is talking about recent research revealing that some people may have immunity defenders called T-cells which could determine how their body reacts to COVID-19.According to the CDC, when the body fights an infection, the immune system remembers what it learned about how to protect the body against that disease.The body will retain a few specific T-cells known as memory cells - that will alert and help the immune system identify and produce antibodies to attack the foreign germ if it enters the body again."Viruses that look alike can sometimes elicit the same kinds of immune responses," said Hildreth.Hildreth says there are six strains of coronavirus that affect humans going back to the 1960s and some result in seasonal common colds.He says if you were infected with one of these viruses in the past it can determine the severity of the toll COVID-19 would take on your body now."There’s the possibility that a response to one of them gives you a partial to another because they have genetic similarities," said Hildreth.Hildreth says this doesn't mean a person has complete immunity to COVID-19."There’s strong evidence that you may not be immune to the virus, but you’ll have an immune response that recognizes SARS partially just because those two viruses look so much alike."Hildreth says this can help with treatments and even vaccinesThis story was originally reported by Kelsey Gibbs at WTVF. 1756

As the nation mourns the passing of Sen. John McCain, Arizona Republicans are holding a Senate primary Tuesday in which one of the candidates suggested the announcement that McCain was stopping medical treatment was timed to hurt her campaign.Kelli Ward, a former state senator who has courted the far-right during her campaign, suggested on Facebook Saturday that McCain's family released its statement saying the senator was ending medical treatment for brain cancer was timed to hurt her chances of winning Tuesday's primary.Ward staffer Jonathan Williams posted that he wondered whether McCain's statement was released "to take media attention off" Ward's campaign, which was beginning a statewide bus tour. "I'm not saying it was on purpose but it's quite interesting," Williams wrote."I think they wanted to have a particular narrative that they hope is negative to me," Ward responded, according to a screenshot posted by the The Arizona Republic.The news broke that McCain had died hours after Ward's comment. Ward's campaign did not respond to a request for comment on the Facebook post.On Monday, less than two days after McCain died of brain cancer, Ward tweeted, "Political correctness is like a cancer!"The attacks and insensitive remarks about McCain are just the latest in a heated primary race that has seen all three candidates align themselves with President Donald Trump, who attacked McCain relentlessly for three years, rather than McCain or retiring Sen. Jeff Flake, whose seat they are seeking to fill.Their decisions show how the path McCain cut through the Trump era -- breaking with the President on foreign policy, health care, immigration and more -- complicated his relationship with diehard Republicans in a state where the GOP electorate is now demanding fealty to Trump.Ward faces Rep. Martha McSally and former Maricopa County Sheriff Joe Arpaio in Tuesday's primary for Arizona's other Senate seat. McSally is seen as the strongest general election candidate to face likely Democratic nominee, Rep. Kyrsten Sinema.McCain fended off Ward's challenge in a 2014 primary. Since then, she's made a series of insensitive comments as McCain battled brain cancer.She called on McCain to step down last year, calling him old and near "the end of life" before his diagnosis and said afterward he should resign "as quickly as possible."Ward closed the race barnstorming the state on a bus tour with right-wing media personalities Mike Cernovich and Tomi Lahren, as well as Rep. Paul Gosar."Are we going to elect another senator cut from the same cloth as Jeff Flake and John McCain?" Ward asked the crowd at a campaign event Friday, eliciting shouts of "No!"After McCain's death, Ward tweeted: "We are saddened to hear of the passing of @SenJohnMcCain. His decades of service will not be forgotten by the men & women of Arizona. May God grant the McCain family comfort and peace during this difficult time."McSally, the Republican establishment's preference in the race, has mostly remained silent on McCain during the primary.But McSally's omission of McCain's name when touting her support for the National Defense Authorization Act, which was named in McCain's honor, when McSally joined Trump at a signing ceremony at Fort Drum in New York, angered McCain's daughter Meghan McCain.McSally's "inability to even mention my father's name when discussing the bill named in his honor is disgraceful (just as it was with Trump)," Meghan McCain tweeted. "I had such higher hopes for the next generation of leadership in my home state."Throughout the campaign, McSally has sought to avoid any distance between herself and Trump.On Thursday, McSally sought to dodge last-minute controversy that could undercut her primary campaign, repeatedly avoiding reporters' questions about whether she considers Trump honest and trustworthy. The questions came after Trump attorney Michael Cohen's guilty plea and claim that Trump knew about hush payments to alleged mistresses during the 2016 campaign. McSally refused to address Trump, saying only that Cohen was "all over the map, contradicting himself, lying in order to save his ass."After McCain's passing, McSally tweeted, "John McCain was one of Arizona's greatest Senators, one of our country's finest statesmen, and an American hero who risked his life to defend this great nation. He loved this state, and he loved this country."I pray that God comforts Cindy and the entire McCain family. My heart is with them, and Arizona grieves with them."Arpaio, who was pardoned by Trump last year after being convicted of criminal contempt related to his hardline immigration tactics, complained in a since-deleted tweet on Friday that Cindy McCain had blocked him on Twitter."I tweeted out my thoughts & prayers for" McCain, his campaign account tweeted, and Cindy "BLOCKS me on twitter?"Arpaio tagged Trump and several news outlets in the tweet.The-CNN-Wire 4934

Astronomers looking at the atmosphere in neighboring Venus see something that might just be a sign of life.In a study published Monday, researchers from Cardiff University, MIT and elsewhere say they found the chemical signature of a noxious gas called phosphine.On Earth, phosphine is associated with life. It's found at the bottom of ponds, in badger guts and in penguin guano.Venus’ phosphine was observed in a narrow, temperate band within the planet’s atmospheres, where temperatures range from 30 to 200 degrees Fahrenheit. Scientists have speculated that if life exists on Venus, this layer of the atmosphere, or cloud deck, is likely the only place where it would survive, according to MIT.“This phosphine signal is perfectly positioned where others have conjectured the area could be habitable,” said the study’s co-author and EAPS Research Scientist Janusz Petkowski.Astronomers tried to figure out other, non-biological ways it could be produced and came up empty.“It’s very hard to prove a negative,” said Clara Sousa-Silva, research scientist in MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS). “Now, astronomers will think of all the ways to justify phosphine without life, and I welcome that. Please do, because we are at the end of our possibilities to show abiotic processes that can make phosphine.”Outside experts — and the study authors themselves — say the research is tantalizing but not yet convincing. 1454

Australia is ordering automakers to recall more than two million vehicles fitted with potentially deadly airbags.The Australian government said Wednesday that the cars contain airbags made by Takata, the Japanese company at the heart of a scandal that has led to tens of millions of vehicle recalls around the world in recent years.Takata airbags have been linked to at least 23 deaths globally, including one in Australia, according to a statement by the Australian Treasury. A defect can cause the airbags to explode and blast shrapnel into drivers and passengers.Voluntary recalls in Australia have previously been announced by big car brands including BMW, Chevrolet, Honda, Nissan, and Toyota. But the government said those steps haven't been enough to deal with the danger, leaving around 2.3 million vehicles with the defective airbags still on the country's roads."The voluntary recall process has not been effective in some cases, and some manufacturers have not taken satisfactory action to address the serious safety risk which arises after the airbags are more than six years old," said Michael Sukkar, an assistant Australian Treasury minister.The new compulsory recall includes models made by major carmakers such as Ford, Mercedes Benz, Tesla and Volkswagen.The total number of affected cars in Australia is 4 million, or nearly one in five passenger vehicles on the country's roads. All the faulty Takata airbags have to be replaced by the end of 2020, according to the government.Wednesday's announcement followed an investigation by Australia's consumer watchdog, the Treasury said.Takata's faulty airbags have led to massive recalls around the world over the past decade. In the United States, more than 40 million vehicles were affected, and authorities say the recalls could take until 2023 to complete.The scandal led to the slow and painful demise of Takata, which started out as a textile manufacturer more than 80 years ago and later came to specialize in seat belts and other auto safety equipment.The company has pleaded guilty to corporate criminal charges and agreed to pay a billion fine in the U.S. It filed for bankruptcy last year and much of its operations are being taken over by Key Safety Systems, a Chinese-owned company based in Michigan. 2323

BALTIMORE — A 79-year-old New York woman lost thousands of dollars after she fell for the "grandparent scam."Earlier this week, the woman received a call from someone posing as her granddaughter. The woman on the phone said, "Grandma, I need help," then handed the phone to someone claiming to be her lawyer.Susan Mayorga's mother thought it was her eldest granddaughter on the phone and agreed to hear the man out."He said, you need to send me ,000 immediately in cash, wrapped in a magazine, here's the address, send it overnight early delivery UPS, and everything will be cleared up," said Mayorga.Mayorga's mom went straight to the bank, then to UPS where she mailed ,000 in cash to 208 South Loudon Avenue, a vacant home in Baltimore. The next day, she received another call.“[He said], 'Oh, I didn't realize there's a gun involved and gunpowder went off, so it's more than a misdemeanor, we need another ,000,'” said Mayorga.Her mom only had ,000 left, and sent it. But before it got there, Mayorga's mom discovered her granddaughter was fine. She immediately told her children and they got to work calling UPS.“I immediately got the tracking number, I called UPS, and spoke to a supervisor and told them it's a scam, there's cash in the envelope this cannot be delivered. It's a scam, please hold the envelope and have it sent back,” Mayorga said.UPS tracking history shows they received a request to place the order on hold, but it was still delivered.“Someone was outside waiting for it and signed his name at 7 a.m. and took the package and left,” Mayorga said.Last year, 1 in 5 people lost money to impostor schemes like the grandparent scam. The total loss amounted to 8 million, according to the Federal Trade Commission. And scammers get away with it because they know people will do anything for the ones they love.“It's just sad because she doesn't have a lot of money and she’s like, I would do anything, give my last penny for my grandchildren, so it's just extra sad,” said Mayorga.Mayorga’s mother called the scammer and he answered. He said he received the package but wanted to know why she tried to hold it up. When she said she knew it was a scam, he threatened her then hung up.UPS said they're investigating what happened to the package. 2315
