NASHVILLE, Tenn. - We’ve known for months about the dangers of the coronavirus spreading in crowded public places but we are now learning new information about the danger of COVID-19 spreading inside your home.The new study from Vanderbilt University Medical Center reveals how vulnerable family members can be inside a home where someone has contracted the coronavirus."What we found is COVID spreads very rapidly and very quickly inside a home," said Dr. Keipp Talbot of Vanderbilt University Medical Center.Just how fast? The study found half of all family members in a home with someone infected with COVID-19 will also get COVID-19, usually within just five days."Once it's in your house, it's very hard to keep from spreading, and you don't know who in your home will be susceptible, and they'll need to be hospitalized," Talbot said.The research adds a new dimension to public health guidelines that largely focus on social distancing outside your home -- guidelines that doctors say work if everyone in the home follows those guidelines while outside."However, if you or anyone in the family goes outside the bubble, and does anything that's risky -- large groups, bars, not wearing your mask -- they can come back into that bubble and put everyone in that bubble at risk," Talbot said.This story was first reported by Jason Lamb at WTVF in Nashville, Tennessee. 1379

MORGANTOWN, W.V. – Murder hornets have had their time in the spotlight. Now, scientists say they've discovered “zombie cicadas.”It's a playful name from researchers at West Virginia University, who say they've found that a parasitic fungus, called Massospora, can play mind games on cicadas, causing them to infect others.Researcher showed that the psychedelic fungus can manipulate male cicadas into flicking their wings like females – a mating call – which tempts unsuspecting male cicadas and infects them.The fungus contains chemicals like those found in hallucinogenic mushrooms, according to research published in the journal PLOS Pathogens.“Essentially, the cicadas are luring others into becoming infected because their healthy counterparts are interested in mating,” said Brian Lovett, study co-author and post-doctoral researcher with the Davis College of Agriculture, Natural Resources and Design. “The bioactive compounds may manipulate the insect to stay awake and continue to transmit the pathogen for longer.”The authors of the study compared the effects of the fungus to a “B-horror movie.” Massospora spores gnaw away at a cicada’s genitals, butt and abdomen, replacing them with fungal spores. Then, Lovett says they “wear away like an eraser on a pencil.”Lovett also compared the transmission of the behavior-modifying virus to rabies. He says both rabies and entomopathogenic fungi enlist their living hosts for successful “active host transmission.”“When you're infected with rabies, you become aggressive, you become afraid of water and you don't swallow,” Lovett said. “The virus is passed through saliva and all of those symptoms essentially turn you into a rabies-spreading machine where you're more likely to bite people."In that sense, Lovett says many of us are familiar with active host transmission.“Since we are also animals like insects, we like to think we have complete control over our decisions and we take our freewill for granted,” he said. “But when these pathogens infect cicadas, it's very clear that the pathogen is pulling the behavioral levers of the cicada to cause it to do things which are not in the interest of the cicada but is very much in the interest of the pathogen.”Researchers say cicada nymphs could encounter Massospora in their 17th year as they emerge from the ground to molt into adults or on their way down to feed on roots for 17 years.“The fungus could more or less lay in wait inside its host for the next 17 years until something awakens it, perhaps a hormone cue, where it possibly lays dormant and asymptomatic in its cicada host,” said co-author Matthew Kasson.As grotesque as an infected decaying cicada sounds, researchers say they’re generally harmless to humans. They also reproduce at such a rate that the fungi’s extermination of hordes of cicadas has little effect on their overall population.“They're very docile,” Lovett said. “You can walk right up to one, pick it up to see if it has the fungus (a white to yellowish plug on its back end) and set it back down. They’re not a major pest in any way. They’re just a really interesting quirky insect that’s developed a bizarre lifestyle." 3172

MILWAUKEE, Wisconsin — The parents of a 9-year-old Milwaukee girl shot and killed by her brother over the weekend have been criminally charged.Marcel Antonio Jelks, 32, and Talisha Lee, 29 both faces charges. Jelks has been charged with child neglect resulting in death and possession of a firearm by a felon. Lee has been charged with child neglect resulting in death, and furnishing a firearm to a felon.According to Milwaukee Police's preliminary investigation, Miyanna was accidentally shot by her brother — who is a minor — in their home in the 4500 block of North 38th Street just after noon on Saturday. She was brought to a local hospital where she was pronounced dead. Police say the brother was been taken to the Milwaukee County Children's Court Center. "She was a beautiful, young girl. She was smart, intelligent. She was just 9 years old," said Jay Jones, a family friend.Jones said seven children live in the house with their mom and dad and he doesn't believe the father knew their was a gun inside the house."They are not the type of people to put their kids in no type of danger or anything like that," he said.If convicted, Lee faces 25 years in prison. Jelks could be sentenced to an additional 10 years due to his criminal history. 1305

MoviePass, the struggling movie subscription service, will limit customers to three movies per month.The company is trying to burn less cash so it can stay in business.Under the previous plan, customers could see one movie per day in theaters. The change to three movies per month takes effect August 15. MoviePass says 85% of its customers already see no more than three per month.The company also announced Monday that it will keep the monthly subscription price at .99. It is backing away from a plan, announced just last week, to raise the price to .99.MoviePass CEO Mitch Lowe described the change in an interview earlier Monday with The Wall Street Journal.The stock of MoviePass's parent company, Helios and Matheson, closed last Friday at just 7 cents.The-CNN-Wire 785
