...presence will also have a beneficent impact on the countries involved. The huge new ports that are being scooped out along the coasts of Viet Nam and Thailand should permanently boost the economies of both nations. Vast, U.S.-banked civilian-aid programs are aimed at eradicating the ancient ills of disease, illiteracy and hunger...
Riesman thinks that this problem is more acute at Harvard than at any other college in the country, because of Harvard's reputation and standards, its size, and the impact of the graduate school complex on the College. At first, Riesman says, the presence of graduate schools improved the college atmosphere and gave college a new level of seriousness. But in the middle of a graduate community an elite college such as Harvard "suffers from a surfeit of its virtues." College life becomes "dehydrated"; nothing can be done or prized for its own sake because each step is preparatory...
...change "is less a policy issue than a technical issue," Wilcox said, but he noted that it will nevertheless have a significant impact on the freshman program. He believes it will encourage advisors to regard the list as restricting freshmen to certain courses but as recommending certain courses for them. Many freshmen who would be qualified to take middle-level courses and would be welcomed by professors are discouraged from enrolling by the need to get special permission...
Whether the end result is a deadly illness or a striking change in the next generation, the impact of genetic mutations caused by radiation is not fully understood. To learn more about these effects, Cornell University Scientists Richard Holsten, Michiyasu Sugii and Frederick Steward conducted an experiment of elegant simplicity. They irradiated single carrot cells in a growth-stimulating broth of coconut milk, planning to grow them into complete plants. Thus any mutations that showed up on the complete plan could be traced back with assurance to radiation-caused changes in the chromosomes of a single microscopic cell...
...living cells, the Cornell discovery also suggests that humans who are exposed to extensive radiation may produce the questionable chemicals in their own bodies. And this suggests that some of the cellular damage that results from radioactivity may be caused by those chemicals-not only by direct impact of the high-energy particles that most scientists have held responsible for altering or destroying chromosomes. If this proves to be true, positive identification of the sugar-derived compounds might someday lead to the development of medicines that could alleviate or prevent many forms of radiation sickness...
