![In a study, ORNL researchers concluded that the most direct path to plastic upcycling is through designing polymers specifically for reuse, which would allow the material to be converted into high-value products.

Oak Ridge National Laboratory researchers determined that designing polymers specifically with upcycling in mind could reduce future plastic waste considerably and facilitate a circular economy where the material is used repeatedly.

Switchgrass is not known to interact with this type of fungi naturally; the added PtLecRLK1 gene tells the plant to engage the fungus.

An ORNL team has successfully introduced a poplar gene into switchgrass, an important biofuel source, that allows switchgrass to interact with a beneficial fungus, ultimately boosting the grass’ growth and viability in changing environments.

New data hosted by Oak Ridge National Laboratory is helping scientists around the world understand the secret lives of plant roots as well as their impact on the global carbon cycle and climate change.
![Scientists at Oak Ridge National Laboratory added new plant data to a computer model that simulates Arctic ecosystems, enabling it to better predict how vegetation in rapidly warming northern environments may respond to climate change.](/sites/default/files/styles/list_page_thumbnail/public/2021-08/P7040032cc_small_0.jpg?h=827069f2&itok=0cPOEjIi)

![A team of scientists found that microbes at the SPRUCE experiment in the Minnesota peatlands are increasing production of methane under warming conditions. Credit: ORNL, U.S. Dept. of Energy](/sites/default/files/styles/list_page_thumbnail/public/2021-07/spruce_0.jpg?h=c282529e&itok=VExEOgns)
Scientists studying a unique whole-ecosystem warming experiment in the Minnesota peatlands found that microorganisms are increasing methane production faster than carbon dioxide production.

A study by Oak Ridge National Laboratory, the University of Copenhagen, the National Park Service and the U.S. Geological Survey showed that hotter summers and permafrost loss are causing colder water to flow into Arctic streams, which could impact sensitive fish and other wildlife.
![Diverse evidence shows that plants and soil will likely capture and hold more carbon in response to increasing levels of carbon dioxide in the atmosphere, according to an analysis published by an international research team led by Oak Ridge National Laboratory.](/sites/default/files/styles/list_page_thumbnail/public/2020-12/Climate%20%E2%80%93%20Global%20change%20analyses.jpg?h=468b42ad&itok=lhTGb-s4)

Researchers at Oak Ridge National Laboratory were part of an international team that collected a treasure trove of data measuring precipitation, air particles, cloud patterns and the exchange of energy between the atmosphere and the sea ice.
