In 1883 the mongooses were let loose in the fields, an approach that proved to be completely uninformed (无知的). As it turns out, rats are active at night and mongooses are active in the daytime. The native rats never came in contact with their natural enemies, and native bird ...

as you can tell if you look out on the city street during an insomniac night. But after 6 a.m., the two-legged, daytime creatures of the city begin to stir; and it is they, not the rats, who bring the rat race. You might think that human beings congregate in large cities because...
In the fourteenth century, rats caused the death of one-third of the world's population by transmitting the dreadful Black Plague that mined Europe. Ironically, it is in fighting diseases that rats have been most useful to humanity. Thousands of specially bred rats are used in research laborat...
Many cities in the world are benefiting from the nocturnal (夜间活动的) activities of a group of people who call themselves guerrilla (游击队的) gardeners. Armed with trowels, spades arid a van full of flowers and plants, guerrilla gardeners turn abandoned urban land into a blaze of colon....
We have previously shown that expression of PKCδ is dynamically regulated by stress and that BNSTPKCδ cells are recruited during bouts of active stress coping. Here, we first show that in vivo activation of this population is mildly aversive. This aversion was insensitive to prior restraint ...
I've always realized that I’m always sleepy, even in the daytime after a good night’s rest. When I’m the passenger in a car, I fall asleep really easily. Even when I'm out sometimes in a large crowd in the dance club, I yawn a lot and would rather be in bed sleeping. I ...
from pale olive green to blackish, with a yellow belly. The rubber boa moves slowly and has a blunt tail. It has been called the “two-headed snake,” Bosworth said, because the blunt tail resembles a second head. This snake typically feeds at night by raiding nests of mice and rats....
Thus, we suggest that the improved EIA developed with MT-pcb-AP is a simple, convenient, and valid method for the estimation of serum melatonin in rats, sheep, and humans. Because the EIA method does not require any radioactive material, it will be available to many investigators who do ...
