Can anything live forever?
长生不老可能吗?
Yes. We are proud to introduce: the immortal jellyfish. What makes the jellyfish Turritopsis nutricula so special is that once it reproduces, it doesn't die, but transforms itself back into its juvenile polyp state. Their adult cells and the whole organism becomes "young" again. Barring any sea-borne dangers, there is no biological reason why it can't live forever.
可能。这里要介绍一种可以长生不老的水母。这种可以永生的水母叫做灯塔水母,它可以在性成熟后重新回到幼虫阶段(水螅状态)。灯塔水母的所有成年细胞和其它生理机制都可以返老还童。只要不被天敌吃掉,理论上说,灯塔水母就可以做到长生不老!
