Phytoremediation
The plastic mulch film and stray bottle caps that turn up in garden beds and compost piles could eventually be broken down by enzymes discovered faster thanks to this kind of AI screening.
Certain enzymes made by microbes can chew through the tough plastic used in soda bottles, turning it back into simple building blocks instead of letting it sit in a landfill for centuries. Finding and improving these enzymes used to take scientists years of slow lab work. This review explains how AI tools now help researchers scan huge databases, predict enzyme shapes, and even design brand-new enzymes much faster, which could speed up real-world solutions to plastic pollution.
Key Findings
AI enables high-throughput screening of PET-degrading enzymes from large biological databases, replacing slower traditional discovery methods
Machine learning models can predict enzyme structure and function, aiding molecular engineering to improve enzyme performance
AI-assisted de novo enzyme design is described as an emerging frontier for creating entirely new PET hydrolases
chevron_right Technical Summary
Scientists are using AI to rapidly find and design enzymes that break down PET plastic (the kind in water bottles) into reusable building blocks, speeding up a process that used to take years of trial and error in the lab.

Artificial intelligence-assisted mining of polyethylene terephthalate hydrolases.
Polyethylene terephthalate (PET) hydrolases efficiently hydrolyze the ester bonds in PET, converting it into valuable monomers or oligomers, offering a sustainable biological solution to global PET...

Street trees cut heat deaths by 39 percent in European cities
Trees in your local park or street aren't just pretty — they are literally keeping people alive during heatwaves, and planting even a modest number of the ri...
Soil health is the capacity of soil to function as a living ecosystem, supporting complex interactions between microorganisms, soil fauna, and plant communities. For plant science, soil health is critical because these biological and chemical soil properties directly control nutrient availability,
