Predator-prey interaction study reveals more food does not always mean more consumption

(NOAA Northeast Fisheries Science Center) Decades of data allow researchers at the NOAA Northeast Fisheries Science Center to look at predator-prey interactions in a different way: among multiple species throughout the water column. They have developed an unusually rich picture of who is eating whom off the Northeastern United States.

Stellar explosion in Earth’s proximity

(Technical University of Munich (TUM)) When the brightness of the star Betelgeuse dropped dramatically a few months ago, some observers suspected an impending supernova – a stellar explosion that could also cause damage on Earth. While Betelgeuse has returned to normal, physicists from the Technical University of Munich (TUM) have found evidence of a supernova that exploded near the Earth around 2.5 million years ago.

Don’t Be Fooled By China’s Phony ‘Carbon Neutral’ Pledge

China’s commitment to become ‘carbon neutral’ by 2060 has excited environmentalists but it should be seen as part of China’s strategy to become the world’s economic and military hegemon. Carbon neutrality by a date as remote as 2060 will not…

Mixing of the planet’s ocean waters is slowing down, speeding up global warming, study finds – Washington Post

The reduced up and down mixing is expected to have sweeping implications beyond just accelerating global warming. It is projected to increase energy available to hurricanes and other storms, reduce essential nutrients for fish in upper ocean layers and diminish…

Many ventilation systems may increase risk of COVID-19 exposure, study suggests

Ventilation systems in many modern office buildings, which are designed to keep temperatures comfortable and increase energy efficiency, may increase the risk of exposure to the coronavirus, particularly during the coming winter, according to new research.

Untapped potential exists for blending hydropower, floating solar panels

Hybrid systems of floating solar panels and hydropower plants may hold the technical potential to produce a significant portion of the electricity generated annually across the globe, according to a new analysis.

The key to lowering CO2 emissions is made of metal

Researchers produce malic acid, which contains 4 carbon atoms, through artificial photosynthesis by simply adding metal ions like aluminum and iron. This solves a problem with current artificial photosynthesis technology of only producing molecules with 1 carbon atom and paves the way to exploring the use of CO2 as a raw material.

Redefining drought in the US corn belt

(University of Illinois College of Agricultural, Consumer and Environmental Sciences) As the climate trends warmer and drier, global food security increasingly hinges on crops’ ability to withstand drought. But are scientists and producers focusing on the right metric when measuring crop-relevant drought? Not exactly, according to new research from University of Illinois scientists, who urge the scientific community to redefine the term.

Validating the physics behind the new MIT-designed fusion experiment

(Massachusetts Institute of Technology) MIT researchers have published seven papers outlining details of the physics behind the ambitious SPARC fusion research experiment being developed by MIT and Commonwealth Fusion Systems.
