They examined how nocturnal light affects the weight, body fat and glucose intolerance (the underlying cause of late-onset diabetes) of male mice.
正如他们在美国科学学术期刊上发表的，它们测试了夜间灯光怎样影响雄性老鼠的体重，脂肪和葡萄糖(糖尿病的潜在病因)。
Up out of the lampshade, startled by the overhead light, flew a large nocturnal butterfly that began circling the room.
灯罩下的一只巨大的蝴蝶，被头顶的光吓得一惊，扑扑飞起，开始在夜晚的房间里盘旋。
Design improvements and energy savers like motion detectors will also reduce the amount of light that beams skyward, which biologists increasingly say disrupts nocturnal wildlife.
设计上的改进和一些感应器之类的节能设备也减少了投向夜空的光束——生物学家们越来越多地提到，这种光干扰到了夜行生物。
When kept in 12 hours of light and 12 hours of darkness the mice - which are nocturnal - began consuming more food when the lights were on as early as the first week.
研究人员将老鼠放在光照下12小时，黑暗中12小时。在有光照的情况下，老鼠(喜欢在夜间活动)开始摄入更多的食物，这种现象早在第一周就表现出来了。
Using mice as models, they learned that intense light enhances fear or anxiety in mice, which are nocturnal, in much the same way that darkness can intensify fear or anxiety in diurnal humans.
把小老鼠当做实验品，他们发现强光增强了老鼠的恐惧和焦虑，因为老鼠属于昼伏夜出的生物，同样，因为人类通常在白天活动，黑暗就增加了他们的恐惧和焦虑。
Red light dissipates beyond about 30 feet (10 meters), so the reddish hue of this fish would appear black in deeper waters, allowing some degree of invisibility for this nocturnal hunter.
红光在10公尺以下的深处就会消散，所以这条鱼身上的红色调会在较深处呈现黑色，让这种夜行性猎食者在某种程度上能隐形。
For example insects like dragonflies make nocturnal flights to lay their eggs using horizontally polarized light as a beacon.
举个例子，像蜻蜓这样的昆虫利用水平偏振光作为夜间飞行产卵的指示信号。
Nocturnal insects, which are usually active in dim light but not in complete darkness, react to contour.
夜出性昆虫常常活动于微暗但不是完全黑暗中，对形状有反应。
