已灭绝猛犸象DNA被培育制成肉丸，有点流口水怎么回事……
据路透社报道，当地时间3月28日，一颗巨大的肉丸在荷兰国家科学博物馆亮相，它是用灭绝已久的猛犸象DNA经细胞培育而成的肉所制成的。
A giant meatball made from flesh cultivated using the DNA of an extinct woolly mammoth was unveiled on Tuesday at Nemo, a science museum in the Netherlands.
据悉，这颗肉丸的主要成分是由绵羊细胞结合猛犸象肌红蛋白的DNA序列混合而成的细胞培育结果。
其中，由于获取的猛犸象DNA序列有部分缺失，也插入了一些他们现存近亲非洲象的DNA来完善部分空白。
The meatball was created by Australian cultured meat company Vow. It was made of sheep cells inserted with a singular mammoth gene called myoglobin.
Since the mammoth's DNA sequence obtained by Vow had a few gaps, African elephant DNA was inserted to complete it.
myoglobin ['maɪəˌgloʊbɪn] n.肌红蛋白
该公司首席科学官赖亚尔解释称，肌红蛋白是赋予肉类色泽和味道的关键成分。不过，这颗带有鳄鱼肉香味的肉丸目前还不能食用。
"When it comes to meat, myoglobin is responsible for the aroma, the colour and the taste", James Ryall, Vow's Chief Scientific Officer explained.
The meatballs aren’t intended for human consumption.
赖亚尔表示，“这里面的蛋白质已经有4000年的历史了，在这个产品被推向市场前必须要进行严格的测试。”
该公司称，这不是愚人节玩笑，他们希望通过此举唤起人们对人造肉的关注，并称这会是真正肉类的可持续替代品。
Vow promises this was not an April Fools' joke - said it wanted to get people talking about cultured meat, calling it a more sustainable alternative for real meat.
