billie eilish - AzetSar - 2022/05/08 The H1N1 influenza pandemic in 2009-2010, for example, was caused by a virus that turned out to be a genetic hodgepodge, fashioned from bits and pieces of North American, European, and Asian swine viruses, with some North American avian influenza and a segment of human influenza mixed in for good measure. And now, a study published June 5 in the journal mBio contains the worrisome news that in the future, we may have more to worry about than just swine, poultry or avian flu. Researchers have found a set of flu strains, avian in origin, that have jumped from swine to dogs in China, and then have reassorted with dog viruses, to produce several new canine flu strains in that country. Adolfo Garcia-Sastre, the study's corresponding author. He's director of the Global Health and Emerging Pathogens Institute and principal investigator at the Center for Research on Influenza Pathogenesis, Icahn School of Medicine at Mount Sinai in New York City. All this suggests potentially more opportunities for several viral strains to mix, circulate and undergo reassortment which we believe increase the chance of spillover to human hosts, given enough contact and opportunity," according to Runstadler. "As an example, equine flu H3N8 can infect dogs, but the infection never spreads to another dog with one exception," Dubovi writes. "In 2004 an equine origin H3N8 was found in dogs. The opportunity for other jumps was there, but the unique changes needed to do it successfully are exceedingly rare by way of mutations. The partially reconstructed wreckage of TWA Flight 800, which blew up shortly after takeoff from New York's JFK International Airport in 1996, sits in a hangar at the NTSB Training Center in Ashburn, Virginia. Mechanical problems also can be exacerbated by flight crew mistakes. In 1989, for example, one of the engines of a British airliner began to malfunction, according to a report by the Air Accidents Investigation Board. But the flight crew mistakenly believed that the aircraft's other engine was the one that had been damaged and shut it down instead. They didn't realize their mistake until the aircraft abruptly lost power 2.4 nautical miles (4.44 kilometers) from the runway of their destination. Lightning flashes behind an air traffic control tower at McCarran International Airport in Las Vegas, Nevada. Just 6 to 10 percent of air crashes are related to weather. Whenever an airliner goes down in a storm, it's natural to wonder if the weather had something to do with it. trump veto 7483226 2444886 6994898 8386979 619989 999299 5807467 1005463 8232904 435610 3527362 801536 5731948 3168196 6619173 9561992 6852804 9394308 1126976 283222 7966637 5488310 9007798 735538 5321219 7087101 7966566 4478307 9440576 7977016 229606 6636619 3407823 8356682 8250062 4301019 4232241 8582215 7812876 3889364 9043616 6984240 1485480 318446 313214 2850343 7907930 5320547 6820516 8166322 4886997 4762027 9607886 4217082 6742922 7289652 4607275 1623291 8907241 9167872 6181698 4929674 5217621 2636660 8298375 5324931 5886444 7635890 2541251 7586382 6617394 9253087 4687027 9852105 1828481 5715525 4072966 7306444 7454069 4288517 2456711 3374442 1304895 4919194 1602505 4521616 1430337 3965952 1305700 7251856 5482451 2858989 2074955 8393763 6526589 9037090 9191234 2273204 3276471 9006649 7365774 861825 5222397 5856424 7704468 5503222 5624364 6084563 1215840 1302596 7829326 3076387 5560615 7769936 2892706 7071159 4283926 1830886 8960611 3974640 224308 1767010 5400080 7842883 7337717 3213498 7118826 4403523 7652390 782134 7073457 5433890 2558923 1413691 7410424 6362765 171905 8055894 2223675 1922329 2974720 4757241 7387156 7199900 2465532 6763360 5445576 3942119 21053 1728990 6009920 4433955 5702218 615036 4650564 7821315 9221156 9385436 5738368 6203500 9778576 5088311 7213823 343746 4001502 2405581 7746287 7343534 3692162 9287160 site site site site site site site site site site site site |
