“#New insight into the Great Dying” Credit: CC0 Public Domain A new study shows for the first time that the collapse of terrestrial ecosystems during Earth’s most deadly mass extinction event was directly responsible for disrupting ocean chemistry. The international study, led by the University of Leeds, highlights the importance of understanding the inter-connectedness of…
“#Three ways blockchain could get the world to act against the climate crisis” The world has failed to halt global warming. Four years after the signing of the Paris Agreement, most experts predict global warming will exceed the agreed thresholds, with disastrous consequences.

Glowing spots on its belly make it nearly invisible against the sunlit waters above. But the…
“#Exploring the diversity of cell gatekeepers could be the key to better crops” Aquaporins inside the plant cell.

“#Could the answer to groundwater resources come from high in the sky?” A new technique developed by Berkeley Lab researchers pairs high-resolution images derived by satellite with advanced computer modeling to estimate aquifer volume change from observed ground deformation. The method could be particularly helpful to managing groundwater resources in drought-prone agricultural regions such as…
“#Matrix imaging: an innovation for improving ultrasound resolution” Conventional and matrix ultrasound images of a volunteer’s calf. Matrix correction of aberrations reveals structures that were previously invisible or had poor resolution in a conventional ultrasound (especially in the areas inside the white lines).
