Manipulating Molecules : The National Nanotechnology Initiative 스크랩

  • Michael E. Davey
  • |

The Administration has requested $495 million for nanotechnology research, a $225 million increase over FY2000. Nanotechnology is a newly emerging field of science where scientists and engineers are beginning to manipulate matter at the molecular and atomic level. Proponents argue that nanotechnology will lead to a new industrial revolution in the 21st century. Scientists note that nanotechnology is still in its infancy, with large scale practical applications 10 to 20 years away. Congressional concerns center around why the Administration requested such a large increase for the NNI, the extent to which the newly established Nano Coordinating Office can successfully fulfill its multi- agency planning and coordinating responsibilities, and what role the federal government should play in ensuring that nanotechnology fulfill its long-term potential broad- based commercial applicaitons. While the Administration requested an 84% increase for nanotechnology, Congress approved a 56% increase($422 million), or %151 million above the FY2000 $271 million finding level.

Recent actoins by the Department of Health and Human Services(HHS) and the National Institutes of Health(NIH) involving human embryonic stem cell research have rekindled debate over the difficult ethical and social issues surrounding embryo and fetal tissue research. Embryonic stem cells, which have the ability to develop into virtually any cell ini theh body, may have the potential to treat medical conditions such as diabetes, Parkinson's disease, and cancer.

Nuclear, Biological, Chemical, and Missile Proliferation Sanctions:Selected Current Law 스크랩

  • 과학기술과 인문사회

The use of sanctions specifically to stem weapons proliferation is a relatively new development in U.S. foreign policy. While earlier legislation required the cutoff of foreign aid to countries engaged iin specified nuclear proliferation activities and mentioned other sanctions as a possible mechanism for bringing countries into compliance with goals of treaties or international agressments, it was not until 1990 that Congress enacted explicit guidelines for trade sanctions related to missile proliferation. In that year a requirement for the President to impose sanctions against U.S. persons of foreign persons engagint in trade of items or technology listed in the Missile Technology Control Regime Annex (MTCR Annex) was added that year to the Arms Export Control Act and to the Export Administration Act of 1979. Subsequently, Congress legislated economic sanctions against countries that contribute to the proliferation of chemical, biological, and nuclear weapons in a broad array of laws.

Taiwan:Major U.S.Arms Sales Since 1990 스크랩

  • 과학기술과 인문사회

This CRS report discusses U.S. arms sales to Taiwan, or Republic of China, and lists sales of significant defense articles and services to Taiwan, approved since 1990. Based on unclassified notices, reports, and interviews, this list includes the date of notification, major item sold, and estimated value. The Twiwan relations Act has governed U.S. arms sales to Taiwan since 1979. Despite the unoffical nature of relations, U.S. arms sales to Taiwan have been significant. Policy issues center on how effetively the Administration is assisting Taiwan's defense and the role of Congress in determining arms sales to Taiwan.

Rapid growth in the number of subscribers of mobile wireless telecommunications services in the United States and abroad is fueling interest and developments in the next generation of wireless technology services, known as 3G. 3G services might include high-speed mobile Internet access and the ability to use the same handset anywhere in the world. Issues related to the implementation of 3G center mainly on the allocation of spectrum and adoption of technology standards by each of the countries developing this new wervice. While some steps have been taken to coordinate these activities, much work remains before 3G services will be available to the American public.
