Correlation vs Causation
Causation is the direct relationship between two things, one thing making the other thing happen, another thing leading to something else.
Correlation is the indirect relationship between two things, the things have similar traits though you can have one without the other.
Example
As ice cream sales increase, the rate of drowning deaths increases sharply.
Therefore, ice cream causes drowning.
The drowning is actually occuring because the people are out of shape and overweight. Icecream doesnt mean people are overweight or out of shape, though the people who eat icecream tend to fit that mold.

DDDDDDDDDDDDDDDT
DDT is well a known pesticide and often viewed from a negative light for its detrimental effects on ecosystems.
A select few have announced they have changed their stance on DDT and believe it a great pesticide to use for killing mosquitoes that may carry Malaria.

Polywater?
So it looks like there was a tiny race in the sciences back in the day when Boris Derjaguin published his and Nikolai Fedyakin's findings of the existance of the water. It was proposed to have a higher boiling point and a lower melting point. As everyone wanted to find this more stable form of water, questions arose.
Eventually the whole thing was proven wrong and the hype over the matter seems to have overtaken the reasoning ability in the scientists involved.
