Tiny Mummy’s ‘Alien’ Appearance Finally Explained
Tiny Mummy’s ‘Alien’ Appearance Finally ExplainedResearchers hope their new research will settle debate over the origins of Ata, a naturally mummified infant found in the Chilean desert. Ata is just six inches tall, with a conical-shaped head and unusually hard bones for her size. Some have claimed that she’s an alien. But a new study published today in the journal Genome Research not only continu
人為的な地震は150年間で728件発生、最新報告 | ナショナルジオグラフィック日本版サイト
8万人以上の死者・行方不明者を出した2008年の四川大地震（M7.9）、記憶に新しい2015年のネパール大地震（M7.8）も人為的な地震だったという。 地震は予測のできない天災だと考えられているが、最近ではそうとばかりは限らないようだ。 10月4日付けの学術誌「Seismological Research Letters」に発表された研究によると、過去約150年の間に、人間の活動が原因の地震が728カ所で起こったという。人間が地震活動に影響を及ぼす例があることは以前から知られていたものの、マグニチュード7.9という大地震も引き起こしたという発表は、他の研究者らを驚かせている。（参考記事：「【動画】奇怪！「呼吸」する道路を撮影」） 地震の回数は現在、世界の一部地域で明確な増加を見せている。自然に起こる地震と同じく、人為的な地震も命に関わる危険をはらんでいる。そうした地震が人間や環境に及ぼす影
If you're disgusted by small holes, you may have trypophobia
If This Photo Disgusts You, You May Have TrypophobiaA new study offers one theory for why trypophobia, or the fear of small holes, causes some people so much disgust. Trypophobia might be one of the Internet's most talked about phobias that you haven't heard of by name. The term is Greek for "boring holes"—trypo—and "fear"—phobia—and amounts to a fear of clusters of small holes. The term entered t
イヌやネコはなぜ死んだ飼い主を食べるのか
イエローのラブラドール・レトリバー。（PHOTOGRAPH BY JOEL SARTORE, NATIONAL GEOGRAPHIC PHOTO ARK） 1997年、ドイツ、ベルリンの科学捜査官が、ある珍しい事件に関する論文を学術誌「Forensic Science International」に投稿した。事件の夜、31歳の男性が母親の家の裏庭にある、物置を改装した小屋にこもっていた。彼はそこで飼いイヌのジャーマン・シェパードと一緒に暮らしていた。 午後8時15分頃、小屋のほうで銃声が鳴ったのを、近隣の人々が耳にした。 45分後、その男性が拳銃で口を撃ち抜いて死んでいるところを母親と隣人たちが発見した。男性の手にはワルサーの拳銃が、テーブルの上には遺書が置かれていた。つらく悲しい出来事ではあるものの、ここまでは特別に珍しいことでもない。ほかと明らかに違っていたのは亡きがらの状態だ。彼の顔
Would your dog eat you if you died? Get the facts.
Would your dog eat you if you died? Get the facts.You might not look at your fur baby the same way after reading this. Is this big black Newfoundland yawning—or contemplating its next meal? Cat owners often joke that their pets would eagerly eat them once they die. But forensic evidence suggests that dogs may pose a higher risk. In 1997, a forensic examiner in Berlin reported one of his more unusu
Cats Domesticated Themselves, Ancient DNA Shows
In true feline form, cats took their time deciding whether to jump into humans’ laps. In a new comprehensive study of the spread of domesticated cats, DNA analysis suggests that cats lived for thousands of years alongside humans before they were domesticated. During that time, their genes have changed little from those of wildcats, apart from picking up one recent tweak: the distinctive stripes an
