Como huesos gigantes plantados en la tierra, a lo largo de la bahía de Chesapeake, en la costa atlántica de Estados Unidos, están apareciendo grupos de troncos de árboles despojados de su corteza. Son bosques fantasmas: los inquietantes restos de lo que una vez fueron bosques de cedros y pinos. Desde finales del siglo XIX, una franja cada vez más amplia de estos árboles ha muerto a lo largo de la costa. Y no volverán a crecer.

科学者たちは最近、ニシオンデンザメ（Somniosus microcephalus）の全ゲノムを解読して長寿の謎を解く新たな手がかりをいくつか発見し、2024年9月に査読前の論文を公開するサーバー「bioRxiv」で発表した。この発見が人間の寿命を400歳まで延ばすことはないかもしれないが、私たちが健康に過ごせる年月を延ばす魅力的な青写真を示している。 人間の思春期は12歳前後に訪れる。しかし、ニシオンデンザメの性的な成熟が始まるのは100歳を超えてからだ。1世紀も続く子ども時代などSFのようだが、現実に、ニシオンデンザメは地球上で最も長生きする脊椎動物で、その寿命はおよそ400年と推定されている。（参考記事：「約400歳のサメが見つかる、脊椎動物で最も長寿」） このサメは、北極海や北大西洋の極寒の深海に潜りながら毎年約1cmずつ成長し、何百年もかけて巨大なおとなとなる。最大クラスの体長はトヨタのプリウス（全長4.6m）よりも大きく、体重は900kgを超える。（参考記事：「【動画】貴重！深海のニシオンデンザメ142匹を撮影」）...

Beginning in December 2020, Hill set out around Adelaide, where she scanned the streets for the vibrant white, yellow, or pink shocks of wild parrot feathers. COVID-19-related lockdowns meant it was difficult for Hill and her colleagues to visit zoos or aviaries to collect the feathers of captive parrots. Instead, they created a community-science initiative to collect feathers from the public.

Every year, the illegal wildlife trade ensnares millions of wild birds in a vast global industry. Poaching for the black market affects a huge diversity of life, including nearly half of all bird species. Songbirds and parrots are particularly popular targets, with thousands illegally caught and traded every year. Nautilus Members enjoy an ad-free experience. Log in or Join now . But proving that a bird sold as a pet was poached from the wild, rather than born in captivity, is difficult.

Like giant bones planted in the earth, clusters of tree trunks, stripped clean of bark, are appearing along the Chesapeake Bay on the United States’ mid-Atlantic coast. They are ghost forests: the haunting remains of what were once stands of cedar and pine. Since the late 19th century, an ever-widening swath of these trees has died along the shore.
