Banana, pineapple and coconut don't just belong in the fridge, they're making their way into fashion now too.

As a punishing drought continues to grip California and other areas, scientists are exploring hardy succulents as a pathway to genetically engineer plants to use less water. Agave and other succulents such as the prickly pear, pineapple and vanilla have evolved to perform a different kind of photosynthesis that enable their survival in semiarid environments. These species absorb most of their carbon dioxide at night rather than during the day, as most plants do, meaning less water evaporates off the leaves through transpiration.
