  摘要：My phone rang after I boarded a plane at the Amsterdam airport, on my way to visit family in the Philippines. It was my former Ph.D. adviser calling to tell me a preprint had just been posted that identified flaws in a paper we'd published in Nature looking at how forestry practices affect streamflow. My stomach dropped as he told me the authors of the critique were demanding a retraction. We couldn't talk long-the plane soon took off. I spent the 16-hour flight processing a mix of emotions-di...

  摘要：Hou et al. challenged the giraffoid affinity of Discokeryx and its ecology and behavior. In our response we reiterate that Discokeryx is a giraffoid that, along with Giraffa, shows extreme evolution of head-neck morphologies that were presumably shaped by selective pressure from sexual competition and marginal environments.

  摘要：Ammonia is a critical component in fertilizers, pharmaceuticals, and fine chemicals and is an ideal, carbon-free fuel. Recently, lithium-mediated nitrogen reduction has proven to be a promising route for electrochemical ammonia synthesis at ambient conditions. In this work, we report a continuous-flow electrolyzer equipped with 25-square centimeter-effective area gas diffusion electrodes wherein nitrogen reduction is coupled with hydrogen oxidation. We show that the classical catalyst platinum...
