Virginia Tech University: Why don’t trees ‘bleed’ to death when they get injured?
Using a powerful new type of microscope, scientists have discovered how “check valves” in wood cells control sap flow and protect trees when they are injured. The knowledge may lead to better ways of extracting natural chemicals from wood to make products ranging from medicinal polymers to sugars that are the basis for bioenergy systems.
Aarhus University (Denmark): Uphill for the trees of the world
You may need to get out your mountain boots to go for a walk in the woods in the future. A new study shows that forests are to an increasing extent growing on steep slopes all over the world.
The Earth Institute/Columbia University: Wind and Rain Belts to Shift North as Planet Warms, Says Study
As human activity continues to heat the planet, a northward shift of Earth’s wind and rain belts could make a broad swath of regions drier, including the Middle East and American West, while making monsoon Asia and equatorial Africa wetter, says a new study
Science Daily: Improving Salmon’s Success in the Wild and Aquaculture
Have you ever been stressed and forgot what you were doing? Chronic mild stress may explain why many wild salmon don´t return to our rivers and why 20% of farmed salmon production is lost every year.
National Renewable Energy Laboratory (NREL): NREL Calculates Emissions and Costs of Power Plant Cycling Necessary for Increased Wind and Solar in the West
New research quantifies the potential impacts of increasing wind and solar power generation on the operators of fossil-fueled power plants in the West. To accommodate higher amounts of wind and solar power on the electric grid, utilities must ramp down and ramp up or stop and start conventional generators more frequently to provide reliable power for their customers — a practice called cycling.
