摘要：Ice surfaces are closely relevant to many physical and chemical properties, such as melting, freezing, friction, gas uptake and atmospheric reaction(1-8). Despite extensive experimental and theoretical investigations(9-17), the exact atomic structures of ice interfaces remain elusive owing to the vulnerable hydrogen-bonding network and the complicated premelting process. Here we realize atomic-resolution imaging of the basal (0001) surface structure of hexagonal water ice (ice Ih) by using qPl...

摘要：Farmed soils contribute substantially to global warming by emitting N2O (ref. 1), and mitigation has proved difficult(2). Several microbial nitrogen transformations produce N2O, but the only biological sink for N2O is the enzyme NosZ, catalysing the reduction of N2O to N-2 (ref. 3). Although strengthening the NosZ activity in soils would reduce N2O emissions, such bioengineering of the soil microbiota is considered challenging(4,5). However, we have developed a technology to achieve this, usin...

摘要：Lignocellulose is mainly composed of hydrophobic lignin and hydrophilic polysaccharide polymers, contributing to an indispensable carbon resource for green biorefineries(1,2). When chemically treated, lignin is compromised owing to detrimental intra- and intermolecular crosslinking that hampers downstream process(3,4). The current valorization paradigms aim to avoid the formation of new C-C bonds, referred to as condensation, by blocking or stabilizing the vulnerable moieties of lignin(5-7). A...

摘要：Researchers in India fought to develop what could have been the first therapy to use gene-editing to halt a rare neurodegenerative disease. The efforts hold lessons for the messy state of modern drug development.

摘要：The processes that govern human haematopoietic stem cell (HSC) self-renewal and engraftment are poorly understood and challenging to recapitulate in culture to reliably expand functional HSCs1-3. Here we identify MYC target1 (MYCT1; also known as MTLC) as a crucial human HSC regulator that moderates endocytosis and environmental sensing in HSCs. MYCT1 is selectively expressed in undifferentiated human haematopoietic stem and progenitor cells (HSPCs) and endothelial cells but becomes markedly d...
