a,b, Total soil C stocks (a) and the proportion of total soil C that is protected (mineral-associated) (b) as a function of the mean annual temperature (MAT) globally. Each gridcell is colored by the percentage of clay and silt minerals, and best-fit trends are depicted for fine- and coarse-textured soils; here, fine-textured soils were classified as those with >70% clay + silt content and coarse-textured soils with <20% clay + silt content.…

The news: A man with Parkinson’s disease has regained the ability to walk after physicians implanted a small device into his spinal cord that sends signals to his legs.How they did it: Marc, who has had Parkinson’s for around three decades, is the first and only person to have received the new spinal neuroprosthesis, a small device containing electrodes placed under the skin on top of his spinal cord. It works by sending bursts of electrical signals to stimulate the nerves in his spinal cord, which then activate his leg…

Left: the solution is confined by graphene. Right: the solution is confined by stishovite (SiO2).The white, gray, red, and pink balls are the hydrogen, carbon, oxygen, and silicon atoms, respectively. Credit: HKUST CO2 in the deep Earth may be more active than previously thought and may have played a bigger role in climate change than scientists knew before, according to a study by the Hong Kong University of Science and…
