As air temperatures stay elevated through fall months, people may still want clothes that cool them down while outside, especially if they live in cities that stay warmer than rural landscapes. Researchers who previously demonstrated a cooling fabric coating now report on additional tests of a treated polyester fabric in ACS Applied Materials & Interfaces. Fabric treated with the team’s chalk-based coating kept the air underneath up to 6 degrees Fahrenheit cooler in warmer urban environments.

Scientists have developed a bubble-printing technique that enables precise, flexible liquid metal wiring, ideal for wearable sensors and medical implants. By using lasers to guide microbubbles, this method creates ultra-thin, conductive circuits that maintain flexibility and functionality, offering promising applications in wearable and healthcare electronics.

In a review published in SCIENCE CHINA Chemistry, opportunities for industrializing Photoelectrochemical CO₂ reduction (PEC-CO₂R) by minimizing reaction energy consumption to improve reaction efficiency and selectivity are explored. This review summarizes recent advancements in developing Si-based photocathodes for PEC-CO₂R.

In a paper published in National Science Review, several international teams of scientists present a low latency carbon budget that reveals an unprecedented decline in the global land carbon sink in 2023. Using dynamic global vegetation models, satellite fire emissions data, an atmospheric inversion based on OCO-2 measurements, and emulators of ocean biogeochemical and data-driven models, the study provides a fast-track analysis of the 2023 carbon budget. The research highlights how extreme heat, wildfires, and a moderate El Niño contributed to a significant reduction in the land’s ability to absorb CO2, calling for urgent action to address this growing imbalance.
