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?526Please respect copyright.ＰＥＮＡＮＡHe0Y3HvN8n

水熊蟲(Water Bears)，就是其中一種能夠活下來的生物。526Please respect copyright.ＰＥＮＡＮＡUd7zk3jpFm

（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。526Please respect copyright.ＰＥＮＡＮＡADq5u8HhMt

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。526Please respect copyright.ＰＥＮＡＮＡxOO2dH5Xiy

（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。526Please respect copyright.ＰＥＮＡＮＡ4tbDaEsfyc

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。526Please respect copyright.ＰＥＮＡＮＡF7Z1wOD8Fj

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。526Please respect copyright.ＰＥＮＡＮＡIaLy3WEchI
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。526Please respect copyright.ＰＥＮＡＮＡx3wl8Y5tH1
