Bad actors online are gearing up for the election.Experts with the cyber security company Check Point are warning that before, during and after Election Day, you could see clever campaigns to cast doubt on accuracy and results of the election.“You know, in contrast to previous elections, where it's been about very targeted looking to gain access to things, we really think from what we've seen from a research perspective is that it will be a larger attempt to create disruption versus anything else,” said Mark Ostrowski with Check Point.The software company is warning of a flood of memes on social media. They say the goal is to get so many going and people sharing them that algorithms and admins won’t be able to keep up with taking them down.The goal is to spread false information or create disruption.Check Point is sounding the alarm so people can educate themselves and not spread these.“We even have some of our researchers and instant response folks have even seen some evidence or some type of reliable information where regardless of who wins, there are certain mean themes that are going to be saying, hey, this, this is who the victor is regardless of what the actual results are to again to create this indecision To create this division,” said Ostrowski.Obviously, you can simply report an image on any social media site and only share credible sources on election information. 1405

Asked whether President Donald Trump had ever used the N-word, White House press secretary Sarah Sanders would not definitively say, instead referring reporters to a tweet."The President addressed that question directly," she said, adding, "I've never heard him use that term or anything similar."The question comes as former aide Omarosa Manigault Newman has claimed there's a tape of Trump using the racial epithet on the set of his NBC reality show "The Apprentice" -- though there is no evidence such a tape exists.Trump tweeted Monday night: "I don't have that word in my vocabulary, and never have."Pressed specifically on whether any recording of the President using the racial epithet exists, Sanders said: "I can't guarantee anything, but I can tell you that the President addressed this question directly."She maintained that Trump is someone who is "fighting for all Americans," and that his policies are helpful "particularly for African-Americans," citing African-American unemployment statistics.Sanders also claimed Tuesday that Trump's description of his former aide as a "dog" had "nothing to do with race and everything to do with the President calling out someone's lack of integrity."The "dog" comment was one of many insults the President has used to describe prominent African-Americans, but Sanders insisted Trump insults people of other races as well."The President's an equal opportunity person that calls things like he sees it," she said. "He fights fire with fire." 1501

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

Attorney General Jeff Sessions ordered a review Friday into how the Justice Department and FBI respond to indications of potential violence after the bureau said it failed to act on a tip about the shooter in the Parkland, Florida, school massacre.A person close to Nikolas Cruz, the confessed shooter, contacted the FBI on January 5 to report concerns about him, the FBI said in a statement Friday. But the bureau did not appropriately follow established protocols in following up on the tip."The information was not provided to the Miami Field Office, and no further investigation was conducted at that time," the statement said.The stunning admission -- which prompted Florida Gov. Rick Scott to call on FBI Director Christopher Wray to resign -- is sure to raise further questions about whether the FBI could have prevented the shooting at Marjory Stoneman Douglas High School, which left 17 dead.  915
