Key Points

Every year, hundreds of millions of tons of petrochemical-based plastics are produced, much of which ends up in the environment or is incinerated. This exacerbates greenhouse gas emissions and the environmental crisis caused by plastic pollution. Now, a study led by the University of Barcelona has produced a biodegradable bioplastic of high industrial value—polyhydroxybutyrate, or PHB—from unprocessed potato starch in a single 24-hour step, a strategic breakthrough that could help reduce...

Trees may store less carbon than expected in the future

It's intuitive to think that if a tree is photosynthesizing, it's also growing. But that's not necessarily so—and a new study of oak trees, published in the journal Science Advances, found that even as they photosynthesize late into the year, their growth stops by midsummer.

Landscape water velocities across Europe reshape nitrogen pollution risk under climate change

Nitrate pollution is a growing global environmental challenge due to the extensive use of fertilizer. A study published in Science, led by the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) with the Helmholtz Center for Environmental Research (UFZ), shows that both the amount of water moving through landscapes and how fast it moves play a key role in nitrogen pollution risk.
