A good well referenced overview ... Cold Fusion, Transmutation and "Alchemy", Special Relativity Theory: Beyond Criticism, The myth of the null result of the Michelson-Morley experiment, Is the Speed of Light in Interplanetary Space a Constant?, Big Bang Cosmology - Beyond Empirical Falsification, Anti-Gravity, The Second Law of Thermodynamics."Textbooks present science as a noble search for truth, in which progress depends on questioning established ideas. But for many scientists, this is a cruel myth. They know from bitter experience that disagreeing with the dominant view is dangerous - especially when that view is backed by powerful interest groups. Call it suppression of intellectual dissent. The usual pattern is that someone does research or speaks out in a way that threatens a powerful interest group, typically a government, industry or professional body. As a result, representatives of that group attack the critic's ideas or the critic personally-by censoring writing, blocking publications, denying appointments or promotions, withdrawing research grants, taking legal actions, harassing, blacklisting, spreading rumors." 1.
