Several reports, including those from CBC News and Gizmodo, mentioned that the study could help reveal secrets behind bats' extraordinary disease resistance and longevity. CBC News also included details about the study's methodology, such as sequencing genomes from 103 bat species and comparing them to 44 fossil bats, and quoted a study leader, Sonja Vernes, on the dispersal of bats across the planet. Gizmodo's headline, \"We Finally Know Where Bats Came From, and Dracula Would Approve,\" alluded to the popular association of bats with the fictional vampire."],"centre":["Centre-rated reports focused on the study's main finding that bats likely originated in Europe around 65 million years ago. Multiple outlets, such as Kreiszeitung, merkur.de, tz.de, hna.de, and mannheim24.de, stated that 134 researchers from 64 countries analyzed 103 bat genomes and 44 fossil finds, and that the results showed how the animals spread from Europe to Africa, Asia, America, and Australia. Channel News Asia, also rated centre, provided more detail on the study's implications, noting that bats are critical players in global ecosystems and that their evolutionary history has been a puzzle for scientists."],"right":["Right-rated reports primarily focused on the study's conclusion that bats originated in Europe approximately 65 million years ago, contradicting prior assumptions about their place of origin. Headlines from outlets like Chronicle-Tribune, The Messenger, and La Razón posed the question \"Where did bats originate from?\" and stated that new research reveals the answer. Cyprus Mail noted the participation of the University of Nicosia in the international study published in Nature. News-pravda.com mentioned that scientists uncovered the origin and secret of bat longevity, suggesting this could help
