科学美国人60秒:房间灰尘泄露地址及个人信息-托福听力下载

  科学美国人60秒中文翻译:

  The dust that accumulates in the corners of your house does more than just cause allergies and aggravation 房间角落积累的灰尘不仅会造成过敏或加重病情,

  it's also teeming with clues about where you live and who you live with. 而且还会泄露房子的地址及同你生活人的信息。

  That's the finding of a study in the Proceedings of the Royal Society B. 这是根据《英国皇家学会学报》上登载的一项研究所得出的结论。

  Researchers had volunteers at nearly 1,200 homes across the U.S. collect indoor and outdoor dust samples. 研究人员们收集了遍布美国来自1200个家庭志愿接受调查者室内及室外附近的粉尘样本。

  The average home's dust contains about 5,000 types of bacteria and 2,000 types of fungi. 房间中的平均尘埃有大约5000种细菌及2000种的真菌。

  The fungi gave away a lot about a home's location. 真菌会泄露许多房子所在地方面的信息。

  Different regions have different fungal populations, and thus so do houses within those regions. 因为不同的地区有着截然不同的真菌群,而且各个地区房间中的真菌也不相同。

  For example, dwellings around the Great Lakes had very different fungi than did homes in Arizona 比如大湖附近和亚利桑那州房子的菌群就是截然不同。

  because most household fungi originate outside and come in either on people's clothes or through windows and doors. 因为大部分家中的真菌都源自于户外,是从人们的衣物或者门窗进入屋内。

  As for the bacteria, those were strong indicators of the identity of the home's residents. 而至于细菌则会透露房间内所在住户的身份。

  Much of the bacteria was shed by the human body and was a pretty good indicator of a home's gender ratio. 大部分细菌都是从人类身体上脱落并且能够充分表明一个家庭当中的男女性别比例。

  The single-celled organisms also showed whether a pet shared the home 单个的细胞组织也会显示家中是否有宠物等的信息,

  cats and dogs make their own contributions to the indoor bacterial menagerie. 猫猫和狗狗也会在室内产生细菌群体。

  The research could inform forensic investigations and allergy studies. 这项研究能够为法医调查及过敏原研究提供信息。

  In the meantime, what can we take from these findings? 同时我们能从中了解到什么呢?

  Well, you can clean up dust but you can't change its composition. 哦,你可以进行清洁工作,但无法改变细菌的组成成分。

  That is, unless you move. 也就是说,除非你搬家。

  Or make some changes in the pets and people you live with. 或者远离猫狗及选择别人和你一起生活。
