Problem: Background: Maurice Robert "Mike" Gravel (; born May 13, 1930) is an American politician who was a Democratic United States Senator from Alaska from 1969 to 1981 and a candidate in the 2008 U.S. presidential election. Born and raised in Springfield, Massachusetts, by French-Canadian immigrant parents, Gravel served in the U.S. Army in West Germany, and he later graduated from the Columbia University School of General Studies. He moved to Alaska in the late 1950s, becoming a real estate developer and entering politics. He served in the Alaska House of Representatives from 1963 to 1966 and also became Speaker of the Alaska House.
Context: In the late 1960s and early 1970s the U.S. Department of Defense was in the process of performing tests for the nuclear warhead for the Spartan anti-ballistic missile. Two tests, the "Milrow" and "Cannikin" tests, were planned, involving the detonation of nuclear bombs under Amchitka Island in Alaska. The Milrow test would be a one megaton calibration exercise for the second, and larger five megaton, Cannikin test, which would measure the effectiveness of the warhead. Gravel opposed the tests in Congress. Before the Milrow test took place in October 1969, he wrote that there were significant risks of earthquakes and other adverse consequences, and called for an independent national commission on nuclear and seismic safety to be created; he then made a personal appeal to President Nixon to stop the test.  After Milrow was conducted, there was continued pressure on the part of environmental groups against going forward with the larger Cannikin test, while the Federation of American Scientists claimed that the warhead being tested was already obsolete. In May 1971, Gravel sent a letter to U.S. Atomic Energy Commission hearings held in Anchorage, in which he said the risk of the test was not worth taking. Eventually a group not involving Gravel took the case to the U.S. Supreme Court, which declined to issue an injunction against it, and the Cannikin test took place as scheduled in November 1971. Gravel had failed to stop the tests (notwithstanding his later claims during his 2008 presidential campaign).  Nuclear power was considered an environmentally clean alternative for the commercial generation of electricity and was part of a popular national policy for the peaceful use of atomic energy in the 1950s and 1960s. Gravel publicly opposed this policy; besides the dangers of nuclear testing, he was a vocal critic of the Atomic Energy Commission, which oversaw American nuclear efforts, and of the powerful United States Congress Joint Committee on Atomic Energy, which had a stranglehold on nuclear policy and which Gravel tried to circumvent. In 1971, Gravel sponsored a bill to impose a moratorium on nuclear power plant construction and to make power utilities liable for any nuclear accidents; in 1975, he was still proposing similar moratoriums. By 1974, Gravel was allied with Ralph Nader's organization in opposing nuclear power.  Six months before U.S. Secretary of State Henry Kissinger's secret mission to the People's Republic of China (P.R.C.) in July 1971, Gravel introduced legislation to recognize and normalize relations with China, including a proposal for unity talks between the P.R.C. and the Republic of China (Taiwan) regarding the Chinese seat on the U.N. Security Council. Gravel reiterated his position in favor of recognition, with four other senators in agreement, during Senate hearings in June 1971.
Question: What resulted after he publicly opposed the policy?

Problem: Background: Richard Charles "Dick" Lewontin (born March 29, 1929) is an American evolutionary biologist, mathematician, geneticist, and social commentator. A leader in developing the mathematical basis of population genetics and evolutionary theory, he pioneered the application of techniques from molecular biology, such as gel electrophoresis, to questions of genetic variation and evolution. In a pair of seminal 1966 papers co-authored with J.L. Hubby in the journal Genetics, Lewontin helped set the stage for the modern field of molecular evolution. In 1979 he and Stephen Jay Gould introduced the term "spandrel" into evolutionary theory.
Context: Lewontin has worked in both theoretical and experimental population genetics. A hallmark of his work has been an interest in new technology. He was the first person to do a computer simulation of the behavior of a single gene locus (previous simulation work having been of models with multiple loci). In 1960 he and Ken-Ichi Kojima were the first population geneticists to give the equations for change of haplotype frequencies with interacting natural selection at two loci. This set off a wave of theoretical work on two-locus selection in the 1960s and 1970s. Their paper gave a theoretical derivation of the equilibria expected, and also investigated the dynamics of the model by computer iteration. Lewontin later introduced the D' measure of linkage disequilibrium. (He also introduced the term "linkage disequilibrium", about which many population geneticists have been unenthusiastic.)  In 1966, he and Jack Hubby published a paper that revolutionized population genetics. They used protein gel electrophoresis to survey dozens of loci in the fruit fly Drosophila pseudoobscura, and reported that a large fraction of the loci were polymorphic, and that at the average locus there was about a 15% chance that the individual was heterozygous. (Harry Harris reported similar results for humans at about the same time.) Previous work with gel electrophoresis had been reports of variation in single loci and did not give any sense of how common variation was.  Lewontin and Hubby's paper also discussed the possible explanation of the high levels of variability by either balancing selection or neutral mutation. Although they did not commit themselves to advocating neutrality, this was the first clear statement of the neutral theory for levels of variability within species. Lewontin and Hubby's paper had great impact--the discovery of high levels of molecular variability gave population geneticists ample material to work on, and gave them access to variation at single loci. The possible theoretical explanations of this rampant polymorphism became the focus of most population genetics work thereafter. Martin Kreitman was later to do a pioneering survey of population-level variability in DNA sequences while a Ph.D. student in Lewontin's lab.
