#Plant roots increase carbon emission from permafrost soils

“#Plant roots increase carbon emission from permafrost soils” Credit: Unsplash/CC0 Public Domain A key uncertainty in climate projections is the amount of carbon emitted by thawing permafrost in the Arctic. Plant roots in soil stimulate microbial decomposition, a mechanism called the priming effect. An international research team co-lead by Frida Keuper from INRAE and Umeå…

#Immune system adaptations in cavefish may provide autoimmune disease insight

“#Immune system adaptations in cavefish may provide autoimmune disease insight” Cave and surface forms of the same fish species, Astyanax mexicanus Credit: Rohner Lab, Stowers Institute Cavefish are seemingly insignificant: They are small, they live in tucked away places humans rarely go, and they’re quite common, found on every continent except Antarctica. But researchers from…

#Scientists discover volcanoes on Venus are still active

“#Scientists discover volcanoes on Venus are still active” The 3D rendition above shows two coronae observed on the surface of Venus. The ring-like structures are formed when hot material from deep inside the planet rises through the mantle and erupts through the crust. Research by UMD’s Laurent Montesi found that at least 37 coronae on…
