摘要：The amputation of a salamander limb triggers anterior and posterior connective tissue cells to form distinct signalling centres that together fuel regeneration1. Anterior and posterior identities are established during development and are thought to persist for the whole life in the form of positional memory2. However, the molecular basis of positional memory and whether positional memory can be altered remain unknown. Here, we identify a positive-feedback loop that is responsible for posterio...

摘要：Carbon fibre-reinforced polymers (CFRPs) are used in many applications in the global energy transition, including for lightweighting aircraft and vehicles and in wind turbine blades, shipping containers and gas storage vessels1, 2, 3-4. Given the high cost and energy-intensive manufacture of CFRPs5, 6-7, recycling strategies are needed that recover intact carbon fibres and the epoxy-amine resin components. Here we show that acetic acid efficiently depolymerizes both aliphatic and aromatic epox...

摘要：Drought is one of the most common and complex natural hazards affecting the environment, economies and populations globally1, 2, 3-4. However, there are significant uncertainties in global drought trends4, 5-6, and a limited understanding of the extent to which a key driver, atmospheric evaporative demand (AED), impacts the recent evolution of the magnitude, frequency, duration and areal extent of droughts. Here, by developing an ensemble of high-resolution global drought datasets for 1901-202...

摘要：Climate change threatens global food systems(1), but the extent to which adaptation will reduce losses remains unknown and controversial(2). Even within the well-studied context of US agriculture, some analyses argue that adaptation will be widespread and climate damages small(3,4), whereas others conclude that adaptation will be limited and losses severe(5,6). Scenario-based analyses indicate that adaptation should have notable consequences on global agricultural productivity(7, 8-9), but the...
