Douglas-fir in Klamath Mountains are in ‘decline spiral,’ Oregon State research shows

CORVALLIS, Ore. – Increases in mortality among Douglas-fir in the Klamath Mountains are the result of multiple factors that have the iconic tree in a “decline spiral” in parts of the region, a new study by the Oregon State University College of Forestry and OSU Extension Service indicates.

Oregon State develops catalyst that purifies herbicide-tainted water and produces hydrogen

CORVALLIS, Ore. – Researchers in the Oregon State University College of Science have developed a dual-purpose catalyst that purifies herbicide-tainted water while also producing hydrogen.

Sea stars able to consume kelp-eating urchins fast enough to protect kelp forests, research shows

CORVALLIS, Ore. – A research team including a scientist from Oregon State University has provided the first experimental evidence that a species of endangered sea star protects kelp forests along North America’s Pacific Coast by preying on substantial numbers of kelp-eating urchins.

Researchers develop machine learning model to improve Amazon carbon storage estimates

CORVALLIS, Ore. – A collaboration led by an Oregon State University College of Forestry researcher has used very-high-resolution satellite imagery to develop a machine learning model that aims to improve climate scientists’ ability to estimate carbon stocks in the Amazon.

Feedback loops make climate action even more urgent, scientists say

CORVALLIS, Ore. – An international collaboration led by Oregon State University scientists has identified 26 global warming accelerators known as amplifying feedback loops that the researchers say aren’t being properly included in climate models.

Moisture the key to soils’ ability to sequester carbon, Oregon State research shows

CORVALLIS, Ore. – Soil is the Earth’s second-biggest carbon storage locker after the ocean, and a research collaboration has shown that it’s moisture, not temperature or mineral content, that’s the key to how well the soil carbon warehouse works.

GPS tracking, simulations show optimal locations to help desert bighorn sheep cross freeways

Desert bighorn sheep whose Southern California range is bisected by freeways may one day benefit from Oregon State University modeling designed to show where the animals would be most apt to use overpasses to safely cross the interstates.

As climate warms, drier air likely to be more stressful than less rainfall for Douglas-fir trees

CORVALLIS, Ore. – Douglas-fir trees will likely experience more stress from drier air as the climate changes than they will from less rain, computer modeling by Oregon State University scientists shows.

Oregon State University researchers take key step toward new treatment for hereditary blindness

PORTLAND, Ore. – Oregon State University College of Pharmacy scientists have demonstrated in animal models the possibility of using lipid nanoparticles and messenger RNA, the technology underpinning COVID-19 vaccines, to treat blindness associated with a rare genetic condition.

New analysis of cellular ‘vehicles’ drives a deeper understanding of ALS, Alzheimer’s

CORVALLIS, Ore. – Oregon State University scientists have taken a key step toward better understanding neurodegenerative diseases by using a suite of biophysical techniques to learn more about a motor protein whose malfunction is associated with many disorders.
