Giles Duffield, a biologist at the University of Notre Dame, who studies circadian rhythms.

圣母大学研究昼夜节律的生物学家贾尔斯·达菲尔德说到。

But Duffield and colleagues now collect data on the brown-throated three-toed sloth in the Atlantic Forest.

但达菲尔德和同事现在正在大西洋森林中收集褐喉三趾树懒的数据。

Many education leaders, Duffield said, do not even know about federal money meant to support homeless students.

达菲尔德说，许多教育领导人甚至不知道有用来支持无家可归学生的联邦资金。

Duffield says the sloths can stay in sight-or even in the same tree-for nearly 24 hours.

达菲尔德表示，树獭可以在人们的视线中——甚至在同一棵树上——待近24小时。

But schools now have limited time left to spend federal pandemic assistance money for homeless students, said Barbara Duffield.

但芭芭拉·达菲尔德说，学校现在只剩下有限的时间把联邦疫情救助资金用于无家可归的学生身上。

Duffield's most important piece of equipment for this research may be a comfortable chair.

达菲尔德在这项研究中最重要的设备可能是一把舒适的椅子。

Kovich, Duffield, and Dunlap flipped this morning.

科维奇 达菲尔德 邓拉普今早反转了。

Duffield cared less about whether his colleague would be delicious—that was obvious.

达菲尔德不太关心他的同事是否美味——这是显而易见的。

Duffield says it's not clear if the new schedule adopted by sloths in the Atlantic forests also affects these creatures.

达菲尔德表示，目前尚不清楚大西洋森林树懒采用的新时间表是否也会影响到这些生物。

The stigma that comes with homelessness also can lead families not to tell anyone they do not have housing, Duffield said.

达菲尔德说，无家可归带来的羞耻也会导致一些家庭不告诉任何人他们没有住房。

Duffield says there are few if any studies where researchers monitored sloths over a full 24-hour period.

达菲尔德说， 研究人员在整个 24 小时内监测树懒的研究很少（如果有的话）。

But there's one species in particular that Duffield and colleagues were focused on: Aedes aegypti.

但有一个物种特别受到 Duffield 及其同事的关注：埃及伊蚊。

Duffield: Aedes aegypti sort of evolved alongside humans and is very adept to living within human habitation.

Duffield：埃及伊蚊有点像人类一起进化，非常善于在人类居住的环境中生活。

Duffield: We feel as though this is a nice, simple assay.

Duffield：我们觉得这是一个很好的、简单的检测方法。

Duffield: So possibly the brighter the light, the larger the effect.

Duffield：所以可能光线越亮，效果就越大。

Notre Dame Professor Giles Duffield convinced a colleague to play the role of blood meal for his research on mosquito genetics and behavior.

施温：圣母大学教授贾尔斯·杜菲尔德（Giles Duffield）说服一位同事在蚊子遗传学和行为研究中扮演血粉的角色。

Duffield says there are few if any studies where researchers monitored sloths over a full 24-hour period. This study did exactly that for 29 days.

达菲尔德表示，几乎没有研究人员对树懒进行全天候的监测。而这项研究这样做了29天。

So Duffield and his colleagues created an experiment: they'd monitor the biting behaviors of mosquitoes who had been exposed to pulses of artificial light throughout the night.

因此，达菲尔德和他的同事们设计了一个实验：他们将监测整夜暴露在人造光脉冲下的蚊子的叮咬行为。

Duffield: Yeah, so that's something that we're busy trying to investigate right now: In the original experimentation, we just use broad-spectrum white light.

Duffield：是的，这就是我们现在正忙于研究的事情：在最初的实验中，我们只使用广谱白光。

If schools cannot identify homeless children, " we can't ensure that they have everything they need to be successful in school and even go to school, " Duffield added.

达菲尔德补充说，如果学校无法认定无家可归的儿童，“我们就不能确保他们拥有在学校取得成功甚至上学所需的一切。”
