Biologists are now coming round to the idea that much of nature is not a product of neat family lines, but a messy mass of cross links.

现在生物学家需要重新开始到这种观念，自然界里有许多的东西，并不全是纯净家族血统的产物，恰恰是交叉藕合、杂乱无章的物种。

The molecules of this protein are more or less globular, and are held in that shape by internal cross-links between different parts of the amino-acid chain of which the protein is composed.

这种蛋白质的分子多少像个球形，构成该蛋白质的氨基酸链的不同部分之间有内部交叉联结，正是这种力量使这些分子保持那种形状。

For example, you might allow an agent that cross-links things to see all your data: it would go and add cross links to relevant things onto all the things you have created or collected.

举个例子，你允许代理看你的数据，他会添加与你已创建和收集的事情相联系的链接。

Formaldehyde cross-links proteins, so, if you treated this virus with Formaldehyde, even it was able to enter a cell, it couldn't break down anymore.

甲醛使蛋白质发生交联反应,因此,如果你对病毒使用了甲醛,即使它可以侵入细胞,它也不能够再进行分解

They grew the virus in monkey cell cultures, they purified the virus because you got to get all the other stuff from the cells that you're growing it in a way, they inactivated it by treating it with formalin which is just a formula-- it's just a mixture of Formaldehyde; Formaldehyde cross links proteins.

研究人员将病毒种植在猴细胞内,进行培养,并提纯病毒,在某种程度上,通过这种方法,可以得到所有类型的病毒,研究人员用福尔马林,处理病毒,使其灭活,福尔马林就是甲醛的水溶液,甲醛可以使蛋白质发生交联反应

These like to form cross-links between protein molecules, and thus tend to hold such molecules together.

Validea scans publications and websites, including all the major business magazines, CNBC and discussion groups, and cross-links stocks mentioned in those media with the people who mentioned them and the touters' records.
