Guerrilla Gardening

Guerrilla gardening is the act of gardening on land that the gardeners do not have the legal rights to cultivate, such as abandoned sites, areas that are not being cared for, or private property.

 

Sounds like a fun concept! More info and examples can be heard in the 99 Percent Invisible podcast episode below that is one of my favourites of all time!

Peace Lines

Barricades that divide areas of Northern Ireland to help keep the peace. Also called Peace Walls as many are really walls.

 

These could apply to other places where similar barriers exist, but the term originated and is mostly associated with the complex situation in Northern Ireland. From the 99 Percent Invisible podcast episode below.

Definition: Retrovirus

Retrovirus

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!
