Imagine you and the rest of your expedition are stranded on a distant planet. Food stores are running low, but the local trees produce a lovely chartreuse fruit. It's tasty and full of nutrients, but has the unfortunate side-effect of killing the experimental animals you've tested it on (as illustrated above). So what can you do?"Cum Grano Salis" is a good old-fashioned science fiction problem story that was originally published in a 1959 issue of Astounding Science Fiction. Since figuring out the scientific solution to the problem is the whole point of the story, I won't give it away. But if you want a few hints, you can follow the links below (mousing over the links will probably give it all away):
- chartreuse is the same color as this pigment with this structure, which can have this property.
- Cum Grano Salis means this
(Edited to make the links clearer)
