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

NATIONAL CITY, Calif. (KGTV) - People who live next to the 8th hole at the National City Golf Course are fed up with damage from errant tee shots."It's a huge problem," says Karen Hovik. She says golf balls have broken three windshields on her car and left countless dents and scratches."I watch people, and they try to swing like Happy Gilmore while they're filming it," she says, noting that golfers take aggressive swings and don't seem to care where their ball lands.A chain link fence lines the property between the golf course and the condo complex. Hovik and her neighbors want the city or the course management company to put up tall nets, similar to the ones near the driving range."It's not just property damage," says Hovik. "Somebody could get really hurt and injured by that." Hovik says she's been hit by golf balls several times while walking near her home.A representative from the golf course told 10News they take the issue very seriously, and they've posted signs along the course telling the golfers they are responsible for any damage done by bad shots. They also say they plan a full safety review of the course this year, and that's one issue that will be addressed.Representatives from the National City Parks and Recreation Department have not returned our calls for comment. 1308

Moderator Kristen Welker, with the help of an offstage mute button, helped give Americans a substantive head-to-head debate over leadership that had been missing during the presidential campaign. The NBC News White House correspondent, in her first time moderating a general election debate, kept tight control of the discussion between President Donald Trump and Democrat Joe Biden. Trump, possibly deterred by the mute button, resisted the interruptions that led to criticism of his performance in the first debate. Welker guided the candidates through discussions about the coronavirus, climate change, health care and race in America.While Thursday marked Welker's first time moderating a debate between two nominees, she was among a panel of NBC News moderators who led a Democratic debate last year. Welker earned praise from her colleagues both at NBC News and the White House Press Corps. 905

More than 228,000 pounds of Hormel Spam and other canned meat products are being recalled because they might contain shards of metal, according to the US Department of Agriculture.The department's Food Safety Inspection Service said Saturday that the problem was discovered after four customers complained of metal objects in canned Hormel products. The FSIS did not say how the pieces of metal might have gotten into the products.Throughout the US, 12-ounce metal cans labeled "SPAM Classic" with the designation "EST. 199N" should not be eaten because of a risk of minor oral injuries, FSIS said. The cans have a "Best By" date of February 2021 and carry the following production codes: F020881, F020882, F020883, F020884, F020885, F020886, F020887, F020888 and F020889.Possibly contaminated cans of meat were also distributed in Guam. These 12-ounce metal cans contain "Hormel Food Black-Label Luncheon Loaf." The recalled cans are marked "Best By" February 2021 and carry the production codes F02098 and F02108.The products should be immediately thrown away or returned to the place of purchase, FSIS said. In a statement, Hormel said it was recalling the products "out of an abundance of caution," and that "the health and safety of consumers is our top concern."In 2016, Hormel voluntarily recalled 40 cases of Dinty Moore Beef Stew -- also because of possible contamination by "extraneous materials."The US-based Hormel Foods Corporation sells products in more than 70 countries. 1504
