In 2015, a team of scientists from the United States and China traveled to Tibet to gather samples of Earth's oldest glacial ice.
2015年，來自美國和中國的一組科學家前往西藏收集地球上最古老的冰川樣本。
Earlier this month, they published a paper on the pre-print server bioRxiv detailing their discovery of 28 new virus groups in the 15,000-year-old ice - and warning that climate change could free the ancient viruses into the modern world.
本月早些時候，他們發表了一篇關於印刷前服務器BioRxiv的論文，詳細介紹了他們在1.5萬年前的冰川中發現的28個新病毒群，並警告稱，氣候變化可能會將古老的病毒釋放到現代世界。
The team drilled 50 meters (164 feet) down into the glacier to obtain two ice cores, which then underwent a three-step decontamination protocol.
該小組向下鑽入50米(164英尺)的冰川，以獲得兩個冰芯，然後進行三步去汙方案。
After that, the researchers used microbiology techniques to identify microbes in the samples.
在那之後，研究人員使用微生物學技術來識別樣本中的微生物。
Those techniques revealed 33 virus groups - including, notably, 28 ancient viruses that scientists had never seen before.
這些技術揭示了33種病毒群-值得注意的是，其中包括科學家以前從未見過的28種古代病毒。
"This study establishes ultra-clean microbial and viral sampling procedures for glacier ice, which complements prior in silico decontamination methods and expands, for the first time, the clean procedures to viruses," the team wrote.
該團隊寫道：“這項研究建立了冰川冰的超清潔微生物和病毒採樣程序，它補充了先前的硅去汙方法，並首次擴展了病毒的清潔程序。”
As the team pointed out in their paper, climate change now threatens both our ability to exhaustively catalogue those tiny lifeforms - as well as our ability to stay safe from dangerous ones.
正如該團隊在他們的論文中指出的那樣，氣候變化現在威脅著我們對這些微小生命形式進行詳盡分類的能力，以及我們防範危險生物的能力。
