ATLANTA (AP) — NASA astronaut Kate Rubins told The Associated Press on Friday that she plans to cast her next vote from space – more than 200 miles above Earth. Rubins and two cosmonauts are in Star City, Russia, just outside Moscow. She's preparing for a mid-October launch and a six-month stay at the International Space Station.Texas law allows U.S. astronauts to vote from space using a secure electronic ballot. Mission Control in Houston forwards the ballot to the space station, which Rubins then emails to the county clerk. 539

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 world sputters amid a global coronavirus pandemic that may have originated from bats in China, researchers released a study on Monday indicating that pigs could transmit a pandemic-level flu strain to humans.The Chinese and British based researchers, who published their findings in the Proceedings of the National Academy of Sciences on Monday, said that G4 EA H1N1 viruses in pigs should be closely monitored in human populations, especially among workers in the swine industry.The researchers said that pigs are intermediate hosts for the strain of influenza, which researchers are concerned could spread to humans. A further concern is that humans could spread the virus to other humans, prompting a pandemic. While the study notes that the virus had spread to workers in the swine industry, it likely has not been transmitted from humans to humans.“G4 viruses have all the essential hallmarks of a candidate pandemic virus,” the team of UK researchers wrote.The researchers said G4 viruses bind to human-type receptors, produce much higher progeny virus in human airway epithelial cells, and show efficient infectivity and aerosol transmission in ferrets.While the study indicates cause for some concern, Martha Nelson, an evolutionary biologist at the U.S. National Institutes of Health’s Fogarty International Center, told Science Magazine the chances of a pandemic from G4 viruses are “low,” but added that no one knew the pandemic risk of H1N1 until 2009.“Influenza can surprise us,” Nelson told Science. “And there’s a risk that we neglect influenza and other threats at this time” of COVID-19.Nelson added to Science that given the warning, it would be ideal to produce a human G4 vaccine as the world still needs to be vigilant on other pandemics besides COVID-19.Domestically, the University of Missouri reviewed the research. 1855

Backpage.com, a popular website used to solicit sex was shut down by the feds this week. In Martin County, Florida, deputies are expecting more women to sell themselves on the street now as a result. As much as Backpage made it easier to buy and sell sex, investigations into the illegal trade would often start there. “Backpage, that was like the hub for us. We usually built a lot of our cases,” MCSO Lt. Jesse Carde told Scripps station WPTV in West Palm Beach in an interview. She took WPTV to where they’ll shift more attention as they expect pimps and prostitutes to do the same. “Not that they ever stopped the operations on the street but obviously we expect a little more for traffic,” she said. Generally the popular days for prostitutes to be out on the streets in Martin County are after payday, Friday and Saturday, but now with Backpage shut down, there could be changes. “People that live in neighborhoods that have in the past tended to be hotspots for prostitution, they’re going to probably see resurgence of it at least until the prostitutes, the sex workers, find a different way to use the internet,” MCSO Sheriff William Snyder said. “I’ll take you by the street where we’ve shut down a couple brothels in the neighborhood,” Carde said. These brothels would market themselves online, but also using old school methods such as business cards promoting a shell business and a wink. “As they’re passing out their cards well it’s ‘not really but come by, we’ll take care of you’ and people in the neighborhood already knew what kind of business it was,” she said. Detecting those will rely more on tips and undercover surveillance.With Backpage down, Lt. Carde says it will make it harder for traveling sex workers to find Johns. It will also help curb underage and girls forced into the trade. “I think it’s definitely a win for law enforcement that Backpage has been shutdown,” she said.  1986
