  摘要：Charge density wave (CDW) material 1T- TaS2 was proposed as a quantum spin liquid candidate, on which a cluster Mott insulator comes into being below the transition temperature. We report an experimental ultrafast generation and detection of the coherent amplitude mode (AM) of its CDW state. A salient feature emerges: The coherent CDW mode AM exhibits an unusual T3.56 temperature dependence below 65 K, in addition to the T2 temperature dependence observed in the 65 to 200 K range. This behavio...

  摘要：During cortical development, radial glial cells (neural stem cells) initially are neurogenic, generating intermediate progenitor cells that exclusively produce glutamatergic pyramidal neurons. Next, radial glial cells generate tripotential intermediate progenitor cells (Tri-IPCs) that give rise to cortical astrocytes and oligodendrocytes, and olfactory bulb interneurons. The molecular mechanisms underlying the transition from cortical neurogenesis to gliogenesis, and the subsequent fate determ...
• Robust encoding of stimulus-response mapping by neurons in visual cortex AI翻译

  摘要：Neural activity in sensory cortex is modulated by behavioral and cognitive factors, and this modulation is thought to contribute to the selection of specific sensory information needed to achieve behavioral goals. In contrast, more abstract behavioral variables that are independent of stimulus selection, such as stimulus-response mapping, are thought to be encoded by neurons outside of sensory cortex. We show that information about such mapping is robustly encoded in the responses of neurons i...
• Thiopurine therapy enhances immune checkpoint inhibitor efficacy in low- mutational burden melanoma: A promising anticancer approach AI翻译

  摘要：A key limitation of immune checkpoint inhibitors (ICI) therapy is their reduced efficacy toward cancers with a low tumor mutational burden (TMB). Since low- TMB tumors express fewer neoantigens, they are less responsive to ICI therapy like anti- PD- 1 and anti- CTLA- 4. In preclinical immunocompetent mouse models of low- TMB melanoma, we recently demonstrated that exposure to 6- thioguanine (6TG) significantly improved tumor control by increasing TMB and creating a proinflammatory tumor microe...
• Abrupt changes in algal biomass of thousands of US lakes are related to climate and are more likely in low- disturbance watersheds AI翻译

  摘要：Climate change is predicted to intensify lake algal blooms globally and result in regime shifts. However, observed increases in algal biomass do not consistently correlate with air temperature or precipitation, and evidence is lacking for a causal effect of climate or the nonlinear dynamics needed to demonstrate regime shifts. We modeled the causal effects of climate on annual lake chlorophyll (a measure of algal biomass) over 34 y for 24,452 lakes across broad ecoclimatic zones of the United ...
• Climate change is leading to an ecological trap in a migratory insect AI翻译

  摘要：Many insect migrants rely on favorable seasonal winds to carry out long- range latitudinal migrations. In East China, the annual advance and retreat of the East Asian summer monsoon produces ideal conditions for seasonal range expansion and contraction of many migratory crop pests. However, climate- induced changes in the strength, timing, and location of the monsoon are impacting wind systems which may, in turn, affect migration patterns. We investigated these questions in the rice leafroller...
• Molecular patterns of matrix protein 1 (M1): A strong predictor of adaptive evolution in H9N2 avian influenza viruses AI翻译

  摘要：The H9N2 subtype of avian influenza virus (AIV) emerges as a significant member of the influenza A virus family. However, the varying degrees of epidemiological dominance among different lineages or clades of H9N2 AIVs have not been fully clarified. The matrix protein M1, a key structural component of the virion, plays a crucial role in maintaining the viral structure and lifecycle. To elucidate the intrinsic relationship between the genetic patterns of M1 and the adaptive dynamics of H9N2 AIV...

• Boosted recovery of rare earth elements from mining wastes and discarded NdFeB magnets by tributyl phosphate-grafted ZIF-8 AI翻译

  摘要：The escalating demand for rare earth elements (REEs) highlights the necessity for their sustainable recovery from waste streams and secondary resources. However, this process requires materials with exceptional selectivity and capacity for REEs due to their low concentration and high presence of interfering ions. Herein, we synthesized zeolitic imidazolate framework- 8 (ZIF-8) and subsequently modified it with tributyl phosphate (TBP) to enhance its affinity and selectivity for the recovery of...
