Since the announcement of Pons and Fleischmann in 1989, cold fusion has been considered to be an example of a pathological science. [15] Two panels convened by the US Department of Energy, one in 1989 and a second in 2004, did not recommend a dedicated federal program for cold fusion research. [16]
Knowledge gained during flights proved invaluable in debunking its hypotheses. [36] Other science resulted in a greater understanding of tropical cyclones. In addition, the Lockheed P-3s were perfectly suitable for gathering data on tropical cyclones, allowing improved forecasting of these monstrous storms. [ 36 ]
He Jiankui (China), former associate professor with the Southern University of Science and Technology, was in 2019 sentenced to three years in prison and fined three million yuan (about US$430,000) for illegally carrying out human embryo gene-editing intended for reproduction. [79] The case is called the He Jiankui affair. [80] [81]

[3] The theory of general relativity predicted an expanding or contracting universe, but Einstein wanted a static universe which is an unchanging three-dimensional sphere, like the surface of a three-dimensional ball in four dimensions.
The effects of inbreeding depression, while still relatively small compared to other factors (and thus difficult to control for in a scientific experiment), become more noticeable if isolated and maintained for several generations. [395] Having sex before a sporting event or contest is not physiologically detrimental to performance. [396]
This list includes well-known general theories in science and pre-scientific natural philosophy and natural history that have since been superseded by other scientific theories. Many discarded explanations were once supported by a scientific consensus , but replaced after more empirical information became available that identified flaws and ...
