摘要：The human calcium-sensing receptor (CaSR) detects fluctuations in the extracellular Ca2+ concentration and maintains Ca2+ homeostasis(1,2). It also mediates diverse cellular processes not associated with Ca2+ balance(3-5). The functional pleiotropy of CaSR arises in part from its ability to signal through several G-protein subtypes(6). We determined structures of CaSR in complex with G proteins from three different subfamilies: G(q), G(i) and G(s). We found that the homodimeric CaSR of each co...

摘要：Quantum interference can deeply alter the nature of many-body phases of matter1. In the case of the Hubbard model, Nagaoka proved that introducing a single itinerant charge can transform a paramagnetic insulator into a ferromagnet through path interference2-4. However, a microscopic observation of this kinetic magnetism induced by individually imaged dopants has been so far elusive. Here we demonstrate the emergence of Nagaoka polarons in a Hubbard system realized with strongly interacting fer...

摘要：Magnetar giant flares are rare explosive events releasing up to 10(47)erg in gamma rays in less than 1second from young neutron stars with magnetic fields up to 10(15-16)G (refs. (1,2)). Only three such flares have been seen from magnetars in our Galaxy(3,4) and in the Large Magellanic Cloud(5) in roughly 50years. This small sample can be enlarged by the discovery of extragalactic events, as for a fraction of a second giant flares reach luminosities above 10(46)ergs(-1), which makes them visib...

摘要：It is well established that near-field radiative heat transfer (NFRHT) can exceed Planck's blackbody limit(1) by orders of magnitude owing to the tunnelling of evanescent electromagnetic frustrated and surface modes(2-4), as has been demonstrated experimentally for NFRHT between two large parallel surfaces(5-7) and between two subwavelength membranes(8,9). However, although nanostructures can also sustain a much richer variety of localized electromagnetic modes at their corners and edges(10,11...

摘要：Arctic and alpine tundra ecosystems are large reservoirs of organic carbon(1,2). Climate warming may stimulate ecosystem respiration and release carbon into the atmosphere(3,4). The magnitude and persistency of this stimulation and the environmental mechanisms that drive its variation remain uncertain(5-7). This hampers the accuracy of global land carbon-climate feedback projections(7,8). Here we synthesize 136 datasets from 56 open-top chamber in situ warming experiments located at 28 arctic ...

摘要：Thorium-229 (Th-229) possesses an optical nuclear transition between the ground state (Th-229g) and low-lying isomer (Th-229m). A nuclear clock based on this nuclear-transition frequency is expected to surpass existing atomic clocks owing to its insusceptibility to surrounding fields(1-5). In contrast to other charge states, triply charged Th-229 (Th-229(3+)) is the most suitable for highly accurate nuclear clocks because it has closed electronic transitions that enable laser cooling, laser-in...
