2023 was known as the year of artificial intelligence,and the application of large models emerged one after another.From the beginning of the year,the cognitive intelligence model represented by ChatGPT was born,which quickly detonated the market.In the second half of the year,large-scale models quickly entered a new stage.Many large-scale models moved from technology to commercialization,and each family seized the high ground of data,computing power,scenarios and applications to compete for the right to speak in the large-scale model market.

With the further improvement of the sustainable development concept,more and more Chinese enterprises are accepting the ESG(Environment,Society,Governance)concept.According to data from Mio Tech,up until the end of July,2023,A-shares enterprises with disclosure of ESG information in 2022 accounted for third fourth of the total market value of all A-shares enterprises.About one third of enterprises in the market released ESG reports in 2023,while the proportion was only a quarter in 2022.

Excess soil salinity affects large regions of land and is a major hindrance to crop production worldwide.Therefore,understanding the molecular mechanisms of plant salt tolerance has scientific importance and practical significance.In recent decades,studies have characterized hundreds of genes associated with plant responses to salt stress in different plant species.These studies have substantially advanced our molecular and genetic understanding of salt tolerance in plants and have introduced an era of molecular design breeding of salt-tolerant crops.This review summarizes our current knowledge of plant salt tolerance,emphasizing advances in elucidating the molecular mechanisms of osmotic stress tolerance,salt-ion transport and compartmentalization,oxidative stress tolerance,alkaline stress tolerance,and the trade-off between growth and salt tolerance.We also examine recent advances in understanding natural variation in the salt tolerance of crops and discuss possible strategies and challenges for designing salt stress-resilient crops.We focus on the model plant Arabidopsis(Arabidopsis thaliana)and the four most-studied crops:rice(Oryza sativa),wheat(Triticum aestivum),maize(Zea mays),and soybean(Glycine max).

Hyperosmotic stress caused by drought is a detrimental threat to plant growth and agricultural productivity due to limited water availability.Stomata are gateways of transpiration and gas exchange,the swift adjustment of stomatal aperture has a strong influence on plant drought resistance.Despite intensive investigations of stomatal closure during drought stress in past decades,little is known about how sequential signals are integrated during complete processes.Here,we discovered that the rapid Ca^(2+) signaling and subsequent abscisic acid(ABA)signaling contribute to the kinetics of both F-actin reorganizations and stomatal closure in Arabidopsis thaliana,while STOMATAL CLOSURE-RELATED ACTIN BINDING PROTEIN1(SCAB1)is the molecular switch for this entire process.During the early stage of osmotic shock responses,swift elevated calcium signaling promotes SCAB1 phosphorylation through calcium sensors CALCIUM DEPENDENT PROTEIN KINASE3(CPK3)and CPK6.The phosphorylation restrained the microfilament binding affinity of SCAB1,which bring about the Factin disassembly and stomatal closure initiation.As the osmotic stress signal continued,both the kinase activity of CPK3 and the phosphorylation level of SCAB1 attenuated significantly.We further found that ABA signaling is indispensable for these attenuations,which presumably contributed to the actin filament reassembly process as well as completion of stomatal closure.Notably,the dynamic changes of SCAB1 phosphorylation status are crucial for the kinetics of stomatal closure.Taken together,our results support a model in which SCAB1 works as a molecular switch,and directs the microfilament rearrangement through integrating the sequentially generated Ca^(2+) and ABA signals during osmotic stress induced stomatal closure.

In this work, the underlying mechanism responsible for the near-linear elastic deformation behavior of a dual-phase Ti-Nb alloy consisting of β and a''phase with large recoverable strain was systematically elucidated.Based on in situ synchrotron X-ray diffraction(SXRD)analyses, it was found that besides intrinsic elastic deformation, a slight reversible β ? a''stress-induced martensitic(SIM) transformation, which proceeded in a consecutive mode under the retarding effect of micro-defects, took place during the near-linear elastic deformation.After unloading, a small amount of residual macroscopic strain remained in the specimen due to the incomplete reverse a''→ β transformation on unloading. The high near-linear elastic deformability of the cold drawing(CD)Ti-Nb alloy has been revealed to be attributed to the coupling actions of intrinsic elasticity as well as the consecutive and reversible β ? a''SIM transformation. Our research may contribute to a new avenue for the design and development of novel dual-phase Ti-based alloys with desirable elastic deformability.

Osteoblasts are essential in the maintenance of human bone homeostasis.1 The abnormal formation and impaired differentiation ability of osteoblasts are pivotal factors leading to bone-related diseases,suggesting that an indepth study of osteoblasts can provide novel treatment strategies for these diseases.2 Human primary osteoblasts are precious experimental models in bone-related research.3 However,the isolation and culture of human primary osteoblasts still have some difficulties and limitations.Here,we refined a method to isolate and culture human primary osteoblasts by taking cancellous bone through a bone tissue sampler and pre-digesting it with pancreatin,which makes the process easier,cheaper,and more efficient.Furthermore,we compared the effects of the subtle changes in isolation and culture methods on the phenotype of human primary osteoblasts and examined the differences in morphology,proliferation,and differentiation between micro-explants cultured osteoblasts(MECOBs)and explants cultured osteoblasts(EC-OBs).
