Data on breeding ecology of a color-band marked population of the ground tit Parus humilis were collected in north Qinghai on the Tibetan plateau, during 2008 and 2009. In spring the birds excavated 0.8-3.2 m long nesting burrows under the ground. First-egg laying occurred between late April and late June during which a pair produced one brood. Incubation was done by female alone for 15-16 days and nestling-feeding by both sexes and helpers in any for 23-25 days. Average brood size at fledging was 5.8 （＋ 1.4 SD, 3-8） and all the 27 observed nesting attempts fledged at least one young. At the population level, brood sex ratio did not differ from 1：1. The birds are a territory-living resident, with annual resight rates being 48% （22 of 46） in adult breeders and 10% （7 of 67） in yearlings. Pairs were socially monogamous, of which 23% （9 of 40） contained one and some- times two male helpers, most likely being philopatric sons of the breeders. The formation of cooperative groups is similar to the population in central Tibet but differs from that in south Guansu where breeding ground tits exhibit a high level of annual turnover

Cyclic GMP-AMP synthase(cGAS)is a key sensor critical for the recognition of DNA in the cytosol and catalyzes the synthesis of the second messenger cyclic GMP-AMP(cGAMP),which binds to the adapter protein MITA(also known as STING,MPYS,and ERIS)to initiate the innate immune *** the binding of DNA to and the activation of cGAS are regulated remains poorly *** a biochemical purification approach,we identified poly(rC)-binding protein 1(PCBP1)as a cGAS-associated ***1 was recruited to cGAS in a viral infection-dependent ***1 directly bound to DNA and enhanced cGAS binding to its ligands,which was important for cGAS ***,PCBP1 deficiency inhibited cytosolic DNA-and DNA virus-triggered transcription of downstream effector *** findings suggest that PCBP1 plays an important role in the cGAS-mediated innate immune response to DNA virus infection by promoting the binding of cGAS to viral DNA.

Non-aqueous lithium-oxygen （Li-O2） batteries have been considered as the superior energy storage system due to their high-energy density, however, some challenges limit the practical application of Li- O2 batteries. One of them is the lack of stable electrolyte. In this communication, a novel electrolyte with ethylene sulfite （ES） used as solvent for Li-O2 batteries was reported. ES solvent showed low volatility and high electrochemical stability. Without a catalyst in the air-electrode of Li-O2 batteries, the batteries showed high specific capacity, good round-trip efficiency and cycling stability.

Gel-incorporated single-crystals provide unique combinational properties of long-range order and composite structures, which is desired for semiconducting and conducting materials. However, the reported gel-incorporated single-crystals are limited to insulating crystals. Here, we examine crystals of two typical semiconductors, lead sulfide （PbS） and lead iodide （Pbl2）, grown from both silica gels and agarose gels. In all the four crystal-gel pairs, single-crystals of the cubic phase of PbS and the hexagonal phase of Phi2 were obtained according to the X-ray diffraction analysis. Dissolution of the gel-grown crystals exposed insoluble materials with the shape similar to the original crystals, indicative of gelincorporation inside the crystals. As such, this work creates a facile strategy to construct 3D heterostructures inside serniconducting single-crystals without destroying their long-range order.
