New study reveals how reptiles divided up the spoils in ancient seas

While dinosaurs ruled the land in the Mesozoic, the oceans were filled by predators such as crocodiles and giant lizards, but also entirely extinct groups such as ichthyosaurs and plesiosaurs. Now for the first time, researchers have modeled the changing ecologies of these great sea dragons.

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.

Advancing carbon dioxide catalysis

(University of Delaware) Feng Jiao is a leader in the field of carbon capture and utilization, working on ways to subtract carbon dioxide from the atmosphere by capturing the greenhouse gas and transforming it into another substance altogether. And now he’s received two major Department of Energy grants, totaling $3.5 million, to advance those efforts.

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.

Is it one or two species? The case of the cluster anemones

(Universit√† di Bologna) Their scientific name is “Parazoanthus axinellae” and they are among the most fascinating corals of the Mediterranean Sea. A genetic analysis suggests they may belong to two different species and, therefore, there could be two types of cluster anemone. Researchers claim this may lead to more effective conservation strategies against the negative impact of climate change on this sea population

Untapped potential exists for blending hydropower, floating PV

(DOE/National Renewable Energy Laboratory) 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 an analysis by researchers at the US Department of Energy’s National Renewable Energy Laboratory (NREL).

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.

EU hydrogen strategy

(European Academies’ Science Advisory Council, Leopoldina – Nationale Akademie der Wissenschaften) Hydrogen is an important alternative for sectors that are stuck in the fossil fuel economy. As national governments and European parliamentarians negotiate the EU’s hydrogen strategy, EASAC issues a new commentary.

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.
