Security concerns have prompted the federal departments of State and Homeland Security to tighten the process for issuing visas and to impose rigorous new monitoring procedures for many international students once they enter the United States. Colleges have struggled to comply with new reporting requirements and deal with admitted students whose entry into the country has been delayed by the new procedures.
One result of these problems has been a renewed discussion of the presence of substantial numbers of international students on U.S. campuses. Anecdotal reports suggest that the number of new internati6nal students entering the United States is declining.
The downward trend is consistent with data on the number of student visas being issued by the State Department. Applications by Arab and Muslim men and those of any student seeking to study science had to be sent to Washington for review, and men fro
A. There is a downward trend in the numbers of international students on U.S. campuses.
B. The number of student visas being issued by the State Department is declining.
C. Any student who is pursuing a degree of Arts in America don’t have to be sent to Washingtonfor review.
D. There are still many people in the world who are applying to study in U.S..

Most people have experienced the feeling, after a taxing mental work-out, that they cannot be bothered to make any more decisions. If they are forced to, they may do so intuitively, rather than by reasoning. Such apathy is of ten put down to tiredness; but a study published recently in Psychological Science suggests there may be more to it than that. Whether reason or intuition is used may depend simply on the decision-maker’s blood-sugar level—which is, itself, affected by the process of reasoning.
E.J. Masicampo and Roy Baumeister of Florida State University discovered this by doing some experiments on that most popular of laboratory animals, the impoverished undergraduate. They asked 121 psychology students who had volunteered for the experiment to watch a silent video of a woman being interviewed that had

Two techniques have recently been developed to simplify research and reduce the number of nonhuman primates needed in studies of certain complex hormonal reactions. One technique involves the culturing of primate pituitary (垂体) cells and the cells of certain human tumors. In the other, animal oviduct (输卵管) tissue is transplanted under the skin of laboratory primates. Both culturing techniques complement existing methods of studying intact (完整的) animals.
With an in vitro culturing technique, researchers are deciphering how biochemical agents regulate the secretion of prolactin (催乳激素), the pituitary hormone that promotes milk production. The cultured cells survive for as long as a month, and they do not require serum (血清), a commonly used culture ingredient that can influence cellular function and confou
A. scientists can study the pituitary gland for the first time
B. the procedures are simpler and require fewer laboratory animals
C. the study of intact laboratory animals has now been rendered obsolete
D. researchers were able to discover prolactin
