PTE听力口语练习-科学60秒-Genome Donators

PTE考生目前最大的问题之一就是练习题缺乏。除了有限的基本官方书(PLUS,Testbuilder, OG)之外,就没有题了。很多英语基础不是很扎实的同学很难找到练习材料。墨尔本文波雅思PTE培训学校专门为墨尔本,悉尼PTE考生准备了适合PTE听力阅读练习的科学60秒。各位PTE同学可以练习PTE听力中的summarise spoken text和PTE口语中的retell lecture,PTE听力口语-科学60秒-Frosty Moss练习记笔记技巧和复述。废话少说,下面开始:

Using publicly available information, researchers found they could figure out the identities of 50 individuals who had loaned their genes to science. Karen Hopkin reports

Since the first human genome sequence was published, thousands of people have submitted their DNA for scientific analysis. They made these donations anonymously—or so they thought. Now, using publicly available information, researchers found they could figure out the identities of 50 individuals who had loaned their genes to science. Their results, although not the names of the people, are in the journal Science. [Melissa Gymrek et al., Identifying Personal Genomes by Surname Inference]

Biomedical research depends on the participation of human subjects, and issues of privacy have always been a concern. When scientists share genomic data, they first strip away identifying information, like the individual’s name and date of birth. But is that really enough?

Researchers looked at a specific set of markers in genomes whose sequences were in a public database. And they found that by matching up these markers with sequences that people had submitted to genealogy web sites, they could identify some of the genome donors’ relatives and, with a bit more sleuthing, come up with their actual names.

Of course, many people now post online accounts of what’s on their minds or even on their menus. But even those who are relatively relaxed about their privacy might think twice about their genomes going public.
