There are species where cells and even whole organisms can go into a state called cryptobiosis where their metabolism is suspended but can be revived later. This usually happens when the conditions become too bad for survival (dry/cold etc.) and is reversed once the conditions improve again (rehydration warming up). One prominent and fascinating example are ...

Stretching the limits of what is known a bit, there is an interesting example of a phage (virus that infects bacteria) infecting a photosynthetic bacterium in the ocean that deserves mentioning. What is amazing here is that the phage has certain genes that are required for photosynthesis within its genome. Why does it have these? The phage extends the ...
