1:Joseph Garner, of Stanford University, thinks the answer is to keep the labs cool, but let mice cope with the low temperatures as they do in their natural habitat: not by eating more but by building nests.2:So far, though, no one has a clear idea of how much nesting material is needed to keep mice happy.3:Dr Garner and his colleagues therefore decided to find out.They have just reported their results in the Public Library of Science.

1:斯坦福大学的约瑟?加纳（Joseph Garner）认为，解决办法就是令实验室保持低温，但让老鼠们像在自然环境中一样通过筑巢（而非吃得更多）来自行应对低温。2:不过至今都没有人清楚到底需要多少材料才能让老鼠们筑一个舒适的窝。3:于是约瑟?加纳博士及其同事决定要弄清这点，他们的实验结果刚刚发表在《公共科学图书馆》上。

1:Tennessee’s bill is not unusual: since 2004 similar measures have been offered in no fewer than 13 state legislatures.2:Only in one other state has one become law.3:Many such bills, including Tennessee’s, share a common parent: a “Model Academic Freedom Statute on Evolution” written and posted by the Discovery Institute, a conservative think-tank that has long advocated intelligent design.4:This measure protects teachers’ and students’ rights to present and hear “the full range of scientific views regarding biological and chemical evolution,” but it does little in practice.5:It changes no curriculum and does not expressly lobby for creationism or intelligent design.6:Louisiana’s measure, which has been law for nearly four years, seems to have had no discernible effects.7:Instead, these bills seem a particularly successful bit of signalling.8:They let evolution sceptics express themselves in the right place: within the law and outside the classroom.

1:田纳西州的这个法案并不罕见：自2004年起，至少13个州中有人向立法机构提出类似的法案，除田纳西州外只有1个州的法案正式生效。2:这些法案中的大部分，包括田纳西州的，都有一个共同起源：由探索研究所撰写并发布的《关于进化论的学术自由法规范》。3:探索研究所这个立场保守的智囊长久以来都是宣扬智慧设计论的。4:这个法规保护了老师和学生提出、倾听“关于生物和化学进化论的所有科学观点”的权利，但并没怎么落实。5:法规并没有改变学校的课程，也没有明确地为创世说或智慧设计论进行游说。6:路易斯安娜州的法案生效已将近4年，却似乎没什么明显效果。7:相反，这些法案看来在传达信息方面尤有成效，它们让进化论怀疑者在恰当的场所表达了自己意见。8:所谓恰当，即法律之内，课堂之外。

1: Dr Garner and his team let each of their mice, 36 males and as many females from three strains commonly used in trials, roam free in two cages connected by a narrow tube. 2: One cage was kept constant at one of six temperatures between 20°C and 35°C. 3: The other was maintained at 20°C but was stocked with up to ten grams of finely shredded paper, which the mice could use to weave a nest. 4: The idea was to check whether the animals would rather build a nest in the cooler cage or move to the warmer one, possibly tugging nesting material along with them strand by strand.

1:约瑟?加纳博士及其实验小组让所有老鼠（公鼠、母鼠各36只，属于三个常用于实验的品系）在两个由一条窄通道相连的笼子里自由活动。2:其中一个笼子的温度保持在20-35摄氏度之间（总共有六档温度）。3:另一个温度保持在20摄氏度，但里面储有多达十克撕得很碎的纸条，以供老鼠们用来筑窝。4:实验目的是看看老鼠们是会在更冷的笼子里筑巢还是会移居到更暖的笼子里（可能还会将筑巢用的纸条一条条拖过去）。
