1918 flu pandemic
Perhaps something useful was learned from this experiment, but the risks far outweigh the rewards. The scientists involved should be punished.
The Daily Mail:
A group of scientists is pushing to publish research about how they created a man-made flu virus that could potentially wipe out civilization.
The deadly virus is a genetically tweaked version of the H5N1 bird flu strain, but is far more infectious and could pass easily between millions of people at a time.
The research has caused a storm of controversy and divided scientists, with some saying it should never have been carried out.
