But, in a proof-of-concept study published in ACS' Journal of Agricultural and Food Chemistry, researchers developed a method to produce creatine, carnosine and taurine -- all animal-based nutrients and common workout supplements -- right inside a plant. The system allows for different synthetic modules to be easily stacked together to boost production.

One outcome can be an unpleasant flavor and smell of wine that is made from grapes exposed to smoke. But researchers report in ACS' Journal of Agricultural and Food Chemistry that they have developed a way to lessen this smoke taint to improve the palatability of the wine.

A pilot study found that partially replacing potting soil with glass fragments can speed up plant development and reduce unwanted fungal growth. The researchers will present their results at ACS Fall 2024.
