芭芭拉·弗雷德里克森是研究积极情绪重要性的国际领先权威，她说，人类的基因决定了寻求积极情绪，比如爱和快乐。
Barbara Frederickson, a leading international authority on the importance of positive emotions, says humans are genetically programmed to seek positive emotions such as love and joy.
他的方程序给出了一些关键的变量，比如病毒基因在细胞内的变异速率，这些可以帮助研究人员安全地杀死病毒。
Given a few key variables, such as how often viral genes shuffle inside cells, his equations can provide the minimum mutation rate to safely kill a virus.
比如，我们分析了从精神病学遗传学文献中获取的基因与疾病相关性数据，以了解在那些高估或低估基因影响力的研究之间是否存在什么共性。
For example we used data from gene-disease associations in the psychiatric genetics literature to see whether studies that overestimate or underestimate an effect have anything in common.
研究中收集到的其他基因则承担着更精细的修复工作，比如修复dna的小伤口和错误。
Other genes in the collection have more-precise repair duties, fixing small nicks and mistakes in DNA.
有了计算机的帮助，基因组学的研究人员能够预测基因的位置，并且比较两种基因组，比如黑猩猩与人类的基因组，以确定对进化具有重要意义的基因序列——进而获得关于基因组如何工作的新见解。
With their help, genomics researchers predict gene locations and compare, say, chimp and human genomes to identify sequences of evolutionary importance-deriving new insights about how genomes work.
遗传学和基因研究的重要性不断增强。基因能影响许多事情，比如会影响着我们的长相。吃什么食物可能会引起疾病，需要被治疗。
Genetics, the study of genes, is gaining increasing importance. Genes can influence many things, from whom we look like to what we eat to possible treatments for diseases.
比如细菌可以在受控制的环境中很容易的生长，允许科学家只研究一个基因的作用。
Bacteria can be grown easily in controlled conditions, allowing scientists to study the effects of just one gene, for example.
每个小组的研究者都使用若干基因组，去研究关于人类起源的不同问题，比如人类如何穿越非洲，另一些人又是如何去往澳大利亚。
Each team of researchers used sets of genomes to tackle different questions about our origins, such as how people spread across Africa and how others populated Australia.
比如，杜克大学的研究员甚至声称，基于一个叫做ERCC1的基因的存在，他们的工作是具有生物学意义的。
In one instance, the researchers at Duke even claimed that their work made biological sense based on the presence of a gene, called ercc1.
比如说，在广岛大学的一项研究就说明，我们可以通过对蚕的基因改造获得一种人体所需的胶原质。
For example, research being done at Hiroshima University has shown that your everyday silkworm can be genetically altered to produce a form of human collagen.
