A type of virus that uses RNA as its genetic material. After infecting a cell, a retrovirus uses an enzyme called reverse transcriptase to convert its RNA into DNA. The retrovirus then integrates its viral DNA into the DNA of the host cell, which allows the retrovirus to replicate.
Hear the fascinating story of how retroviruses were found and proven against the vast majority of scientific opinions that deemed the idea to have been nonsense for many years! This is like science-fiction of the nasty kind, found in this Revisionist History podcast episode below!
A reverse transcriptase (RT) is an enzyme used to generate complementary DNA (cDNA) from an RNA template, a process termed reverse transcription.
It’s a cool, but slightly complicated concept. As a result, I’ll leave it to you to read more about it in the link above, or the Revisionist History podcast episode below!
Another Groundhog Day has passed. With this year comes news of a study by Environment Canada that over the past 30 years (CBC story), groundhogs have only been correct 37% of the time in terms of being able to predict an early spring or long winter based on whether or not they see their shadows. For something that is a dichotomy like a coin flip, if you were wrong more than half the time, then flipping the interpretation of the outcomes means you’d be right more than half of the time! With that logic, I propose we reverse the interpretation of results whether or not they see their shadow.
The NEW results should be if the groundhog sees his/her shadow, it’ll be an early spring, and a long winter otherwise!
