Colchicine is a poison for embryo, it interfere with the separation of chromosome during the cell division
The cancer researchers see this as a potential that can be use to stop cancer growth (which made our cell multiplying at uncontrollable rate)

The theory of fluid intelligence is based on the distinction between the fluid and crystal intelligences. The crystal intelligence is based on the knowledge that one has already and the the fluid intelligence is the intelligence to respond to future and unpredictable challenges.
I think that this distinction is very fitting and that the fluid intelligence was probably the one that drove human evolution; and perhaps is the more relevant of the intelligences.
