[漢羅] Tī 青苔頂懸 ê 水熊蟲

這敢是外星人？ 可能毋是，毋過 tī 地球頂懸所有 ê 生物內底，水熊蟲 可能是上倚外星人--ê。 這是因為咱知影講，水熊蟲 就算是無食無啉幾若十冬，嘛猶活會落去。 In tī 溫度 giōng 欲 絕對零度 到 水沸點以上 ê 範圍會當活咧，tī 氣壓 0 以上 到 比 海底 壓力閣較懸 ê 範圍會當活咧，直接 tī 危險 ê 輻射 下底嘛活會落去。 這寡 極端生物 ê 生存適應能力是遮爾強，這捌 tī 2011 年 踅地球 ê 太空船外口 試驗過。 水熊蟲 會遮爾耐操，一部份是因為 in 有法度修復 in 家己 ê DNA，而且 in kā in 身軀內底 ê 水 減到賰幾葩 嘛猶會擋。 有一寡 微型水熊蟲 差一點仔就變做外星生物矣。 Tī 2011 年 ê 時陣，in 按算欲坐火箭到火星 ê 衛星 火衛一 Phobos ，到 2021 年才送轉來到月球。 毋過 2011 年 ê 發射 煞失敗，2021 年 ê 登陸 摔歹去矣。 Tī 地球大部分 ê 所在，水熊蟲 是比 人類 閣較普遍。 這張 加強色彩 ê 電子顯微鏡相片 內底，有一隻 毫米長 ê 水熊蟲 tī 青苔 頂懸咧爬。

[English] Tardigrade in Moss

Is this an alien? Probably not, but of all the animals on Earth, the tardigrade might be the best candidate. That's because tardigrades are known to be able to go for decades without food or water, to survive temperatures from near absolute zero to well above the boiling point of water, to survive pressures from near zero to well above that on ocean floors, and to survive direct exposure to dangerous radiations. The far-ranging survivability of these extremophiles was tested in 2011 outside an orbiting space shuttle. Tardigrades are so durable partly because they can repair their own DNA and reduce their body water content to a few percent. Some of these miniature water-bears almost became extraterrestrials in 2011 when they were launched toward to the Martian moon Phobos, and again in 2021 when they were launched toward Earth's own moon, but the former launch failed, and the latter landing crashed. Tardigrades are more common than humans across most of the Earth. Pictured here in a color-enhanced electron micrograph, a millimeter-long tardigrade crawls on moss.
