科普專欄–薯不揀單 - 深入淺出–能夠對抗紫外線照射的生物

高強度的紫外光、高溫高壓無氧氣，單憑字面來看已經感受到其強大的破壞力，究竟地球上還有沒有生物可以在這嚴峻的環境生存得到?457Please respect copyright.ＰＥＮＡＮＡo7s4fr3kDd

水熊蟲(Water Bears)，就是其中一種能夠活下來的生物。457Please respect copyright.ＰＥＮＡＮＡmVzFZ18FZ5

（圖2）水熊蟲是約長0.5-1mm的小型動物，屬於緩步動物科，約有1300隻品種。457Please respect copyright.ＰＥＮＡＮＡ7iNxhgQL6d

牠們大多聚居在潮濕土壤及青苔裡頭，深海裡頭亦能找到牠們的蹤影，甚至在太空環境亦能生存得到，生命力非常頑強。457Please respect copyright.ＰＥＮＡＮＡn1cFxa3ttC

（圖3）最近有科學家發現（Fig1)，某品種對紫外光呈高抗性的水熊蟲品種，會在紫外光照射底下發出藍光。457Please respect copyright.ＰＥＮＡＮＡvruozRvNb3

他們亦嘗試抽取水熊蟲水溶性的部份，發覺裡頭的色素能夠有效為其他低紫外光抗性的水熊蟲及其他蟲類抵擋紫外光帶來的殺傷力。457Please respect copyright.ＰＥＮＡＮＡ1XU37OZBI7

除水熊蟲外，鸚鵡在紫外光下均會發出螢光，但會否為牠們帶來紫外線的抵抗力還是疑問。457Please respect copyright.ＰＥＮＡＮＡ0T66dGEMjD
而水熊蟲這種抵禦紫外角的色素科學結構，還需進一步的研究才能確立。457Please respect copyright.ＰＥＮＡＮＡGIiYFdx9q2
