▲ Abstract：
Iron-based superconductors (FeSCs) are a fascinating family of materials in which several electronic bands and strong antiferromagnetic (AFM) correlations are key ingredients for competing ground states, including antiferromagnetism, electronic nematicity and unconventional superconductivity. FeTe, unlike its superconducting isostructural counterpart FeSe, has long been considered an AFM metal sans superconductivity. Here we use molecular-beam epitaxy (MBE) to grow FeTe films and perform post-growth annealing under a Te flux. By performing spin-polarized scanning tunnelling microscopy and spectroscopy (STM/S), we demonstrate that the AFM order in as-grown FeTe films is induced by interstitial Fe atoms that disrupt the ideal 1:1 stoichiometry. Notably, the removal of these interstitial Fe atoms through Te annealing yields stoichiometric FeTe films that show no AFM order and instead exhibit robust superconductivity with a critical temperature of about 13.5 K. This superconducting state is further confirmed by the observation of Cooper-pair tunnelling, zero electrical resistance and the Meissner effect. Therefore, our results demonstrate that stoichiometric FeTe is inherently a superconductor, overturning a long-held view that it is an AFM metal. This work clarifies the origin of superconductivity in FeTe-based heterostructures and demonstrates the importance of stoichiometry control in understanding the competition between antiferromagnetism and superconductivity in FeSCs.

▲ Abstract：
The characteristic tides of coastal rivers influence the distribution of estuarine and wetland habitats, the extent of fresh drinking water, carbon and nitrogen cycles, and sediment export to the ocean5. Despite the importance of riverine tides, their range is generally unknown over most of the world’s rivers because the propagation of tidal waves in channels is complex, gauging stations are scarce and conventional nadir altimetry6 has historically been too sparse for use in rivers. Here we use data from the recently launched Surface Water and Ocean Topography (SWOT) satellite to quantify tidal dynamics across 3,172 coastal rivers. Capitalizing on the wide swath coverage of SWOT, we show that over 165,000 river kilometres are influenced by tides. More than 700 million people live near and depend on these coastal transition zones. River size, slope and tidal range at the river mouth influence the extent to which tides propagate within river systems. Natural and artificial obstacles, such as dams, limit tidal propagation in an estimated 16% of all tidal rivers. The tidal dataset opens new possibilities for monitoring and modelling changes in estuarine habitats, fresh drinking water for coastal cities and riverine carbon budgets7 across annual to decadal timescales in response to sea-level rise8, megadrought9, intensifying water extraction and river regulation.

▲ Abstract：
Chemically reactive microbial natural products have enabled therapeutic development1 via their well-established anticancer, antibiotic and antioxidant activities. However, discovery of reactive metabolites is particularly challenging because they may not tolerate traditional bioactivity-guided isolation workflows. Diazo-containing natural products are a subset of highly reactive microbial metabolites that display potent bioactivity3 and enable powerful biosynthetic transformations; however, instability of the diazo group to light, heat, mild acid and mechanical shock9 has precluded their efficient discovery and application. Here we develop a reactivity-based screening approach to capture diazo-containing metabolites and facilitate their discovery by mass spectrometry. This workflow revealed two novel diazo-containing natural products, 4-diazo-3-oxobutanoic acid (1) and diazoacetone (2), from the human lung pathogen Nocardia ninae. Biosynthetic investigations revealed a distinct enzymatic logic for diazo formation involving hydrazone oxidation catalysed by the metalloenzyme Dob3, and its biochemical characterization suggests promising future applications in biocatalysis. Overall, our work highlights the power of reactivity-guided strategies for identifying reactive metabolites and facilitating the discovery of unique enzymatic transformations.
