Shrinking glaciers: Microscopic fungi enhance soil carbon storage in new landscapes created by shrinking Arctic glaciers      (via sciencedaily.com)     Original source 

Shrinking glaciers expose new land in the Arctic, creating unique ecosystems. Researchers studied how microbes colonize these barren landscapes. The study reveals a crucial role for specific fungal species in capturing and storing carbon in the newly formed soil. These findings suggest fungi are essential for future carbon storage in the Arctic as glaciers continue to recede.

Novel spectroscopy technique sheds light on NOx reduction      (via sciencedaily.com)     Original source 

The process that can convert pollution into benign by-products is called selective catalytic reduction, or SCR. Until now, it has been unclear how this reaction actually occurs, and contradictions have long existed between reaction models within the literature. Catalysis researchers used a technology called modulation excitation spectroscopy, or MES, to finally identify the correct pathway.

How researchers are using digital city-building games to shape the future      (via sciencedaily.com)     Original source 

Researchers have come up with exciting and sophisticated new mapping technology enabling future generations to get involved in creating their own future built landscape. They say that planners are missing a real trick when it comes to encouraging and involving the public to help shape their own towns, cities and counties for the future. They also say that games platforms can be used to plan future cities and also help the public immerse themselves in these future worlds.

Melanin from cuttlefish ink as a sustainable biomass resource      (via sciencedaily.com)     Original source 

Melanin is a ubiquitous compound in nature, produced by many organisms. However, its potential as a biomass resource to produce value-added chemicals and materials remains relatively unexplored. In a recent study, researchers investigated the chemical decomposition of melanin derived from cuttlefish ink and showcased its application in the synthesis of biopolymer films and particles. Their efforts will hopefully pave the way to the adoption of melanin upcycling.

Climate change to shift tropical rains northward      (via sciencedaily.com)     Original source 

Atmospheric scientists predict that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator. The northward rain shift would be spurred by carbon emissions that influence the formation of the intertropical convergence zones that are essentially atmospheric engines that drive about a third of the world's precipitation.
