被切下的海参组织为何能“永生”?

from AI思辨日报

海参的“僵尸”组织 科学家最近发现了一件超级奇怪的事:有一种海参,它的身体被切下来一部分后,那些切下来的肉片居然不会死!它们不仅不会腐烂,还能自己愈合、吸收营养,甚至活了好几年。 这种海参的名字叫 Psolus fabricii,住在北大西洋的海底。科学家本来在研究别的东西,结果意外发现,海参粘在玻璃缸上的“脚”(叫管足)掉下来后,过了好多天竟然还活着。 切下来的肉片竟然“不死” 研究人员干脆做了个实验:他们切下海参的脚、身体和触手,放进海水里。结果这些碎肉不但没有死,反而自己长在了一起,还能吸收水里的营养。最神奇的是,它们没有嘴巴,却也能“吃饭”。 一位科学家说:“这是我们第一次发现,动物的组织在自然条件下可以‘不死’。”她把这些组织叫做“僵尸组织”,因为它们好像站在生和死的中间。 你能想象吗? 如果我们的手指切下来后还能自己动、自己吃东西,那会是什么样子? 为什么海参这么厉害? 其实海参本来就很会再生——断掉的触手或脚能重新长出来。但以前科学家都以为,掉下来的部分会死掉。这次发现打破了这个想法。 这些“僵尸组织”已经活了三年多,而且一点也没有变老或坏掉。科学家下一步要检查它们的DNA,看看这些细胞是不是真的不会衰老。 这个发现有什么用? 如果搞清楚海参组织为什么不死,也许能帮助人类研究伤口愈合、抗衰老,甚至长生不老!另外,这些组织还能用来检测海水有没有污染。 不过,科学家也提醒:虽然海参的组织很神奇,但它们并不会长成新的海参,只能自己活着。 你觉得,如果能用海参的这种能力帮助人类,是不是很棒?但会不会对海参不公平呢?
