An international team of scientists has just sequenced a protein crystal located in the midgut of cockroaches. The reason? 最近，一个国际科学家团队确定了蟑螂中肠内的蛋白质晶体的结构序列。为什么要研究这个？ It’s more than four times as nutritious as cow’s milk and, the researchers think it could be the key to feeding our growing population in the future. 因为它的营养价值是牛奶的四倍多。研究人员认为在人口不断增长的将来，蟑螂奶可以成为人类的重要食物。 Although most cockroaches don’t actually produce milk, Diploptera punctate, which is the only known cockroach to give birth to live young, has been shown to pump out a type of ‘milk’ containing protein crystals to feed its babies. 尽管大多数蟑螂自身并不产奶，但有一种斑点折翅类蟑螂，是目前已知的唯一一种胎生蟑螂，它会分泌出一种含有蛋白质晶体的“奶”来喂养下一代。 |
