Microorganisms may provide hope that peatlands can withstand hotter temperatures in a changing climate.

Scientists at the Department of Energy’s Oak Ridge National Laboratory discovered that certain bacteria increase the climate resilience of Sphagnum moss, the tiny plant responsible for storing a third of the world’s soil carbon in peat bogs. Heat tolerant microbes transfer that protection to the plants, helping them survive climate warming.

To optimize biomaterials for reliable, cost-effective paper production, building construction, and biofuel development, researchers often study the structure of plant cells using techniques such as freezing plant samples or placing them in a vacuum. These methods provide valuable data but often cause permanent damage to the samples.

Practical fusion energy is not just a dream at the Department of Energy’s Oak Ridge National Laboratory. Experts in fusion and material science are working together to develop solutions that will make a fusion pilot plant — and ultimately carbon-free, abundant fusion electricity — possible.

Two decades in the making, a new flagship facility for nuclear physics opened on May 2, and scientists from the Department of Energy’s Oak Ridge National Laboratory have a hand in 10 of its first 34 experiments. ORNL researchers and their partners at other national laboratories and universities launched the first experiment on May 11.

Researchers at Oak Ridge National Laboratory are using state-of-the-art methods to shed light on chemical separations needed to recover rare-earth elements and secure critical materials for clean energy technologies.
