Article Synopsis
- The study presents a new technology called temperature-adaptive radiative cooling coating (TARCC) that adjusts its color based on the temperature, inspired by chameleons, to enhance indoor comfort year-round.
- TARCC effectively reflects solar radiation in the summer, achieving significant cooling, while absorbing heat in the winter to provide warmth, resulting in a substantial temperature regulation capability.
- Real-world tests demonstrate that TARCC can save up to 20% in energy costs annually in midlatitude regions, making it a cost-effective and practical solution for sustainable living environments.

Article Abstract
The highly reflective solar radiation of passive daytime radiative cooling (PDRC) increases heating energy consumption in the cold winter. Inspired by the temperature-adaptive skin color of chameleon, we efficiently combine temperature-adaptive solar absorption and PDRC technology to achieve "warm in winter and cool in summer". The temperature-adaptive radiative cooling coating (TARCC) with color variability is designed and fabricated, achieving 41% visible light regulation capability. Comprehensive seasonal outdoor tests confirm the reliability of the TARCC: in summer, the TARCC exhibits high solar reflectance (∼93%) and atmospheric transmission window emittance (∼94%), resulting in a 6.5 K subambient temperature. In the winter, the TARCC's dark color strongly absorbs solar radiation, resulting in a 4.3 K temperature rise. Compared with PDRC coatings, the TARCC can save up to 20% of annual energy in midlatitude regions and increase suitable human hours by 55%. With its low cost, easy preparation, and simple construction, the TARCC shows promise for achieving sustainable and comfortable indoor environments.

The coordination of floral developmental stages with the environment is important for reproductive success and the optimization of crop yields. The timing of different developmental stages contributes to final yield potential with optimal adaptation enabling development to proceed without being impacted by seasonal weather events, including frosts or end of season drought. Here we characterise the role of FLOWERING LOCUS T 3 (FT3) in hexaploid bread wheat (Triticum aestivum) during the early stages of floral development.

The Berkeley comfort models are well-suited for addressing nonuniform, transient, and cold conditions owing to their comprehensible model structures. Integrating these models with thermoregulation models can aid in formulating energy-efficient local warming and heating, ventilation, and air conditioning (HVAC) operational strategies for occupant-centric winter conditioning in battery electric vehicles (BEVs)-a critical step toward their widespread adoption. However, the Berkeley local sensation (LS) model requires accurate consideration of setpoint and setpoint adaptation to ensure reliable predictions.

Understanding the stable isotope changes of soil water, hydrogen, and oxygen under different land cover in karst areas is beneficial for revealing the infiltration and transport processes of soil water, as well as the impact of different land cover on hydrological processes, providing theoretical basis for regional water resource utilization and ecological environment construction. We measured hydrogen and oxygen isotope of soil water in 0-50 cm profiles under four different land covers (bare land, cultivated land, grassland, and shrubland) at the Puding Karst Ecological Station in Guizhou Province from May 2021 to April 2022 through regular field sampling and indoor experiments. The stable isotope changes of hydrogen and oxygen in precipitation and soil water at 10, 25, and 45 cm layers under four land covers were compared and analyzed.

Climate change is disrupting the reliability of photoperiod as a cue signalling seasonal changes in temperature. Temperate and Arctic species are especially vulnerable to this mismatch between photoperiod and temperature because winters are warming more rapidly in these areas relative to the rest of the world. Organisms relying on autumn photoperiods to trigger physiological adaptations to survive winter may incorrectly time the onset of winter and exhibit maladaptive responses.
