The electrocatalytic CO₂ reduction reaction (CO₂RR) serves as an effective approach to convert CO₂ into high-value chemicals and facilitate carbon cycling. Among various products, ethylene (C₂H₄), a crucial industrial feedstock, demonstrates substantial market demand and economic significance. Copper (Cu)-based catalysts exhibit remarkable advantages in CO₂RR to C₂H₄ conversion due to their unique electronic structure and optimal *CO adsorption capacity.

Seedless fruit production, known as parthenocarpy, offers major commercial advantages by improving eating quality, reducing labor costs, and stabilizing yields under poor pollination conditions.

Inspired by snake pit organs, we propose a CMOS-integrated upconverter system achieving room-temperature, 4K ultra-high-resolution short-wave and mid-wave infrared imaging. Utilizing colloidal quantum dot barrier heterojunctions and co-hosted emitting units, the device demonstrates superior luminance and upconversion efficiency. This innovation breaks visible light limitations, advancing applications in night vision, agriculture, and industrial inspection.

Wearable/implantable phototherapy devices offer advantages such as portability, ease of use, and personalized treatment. This article focuses on clinical applications, systematically reviewing the mechanisms and applications of phototherapy, as well as the key challenges faced by existing phototherapy devices. It also proposes the integration of AI and flexible sensing technologies to develop closed-loop diagnostic and therapeutic systems.

This study systematically assessed GI cancer risks during working-age period (15–64 years) across 204 countries from 1990 to 2021. Key findings: (1) In 2021, approximately 1 in 46 individuals developed and 1 in 73 died from GI cancers during working age globally; (2) Colorectal cancer showed the highest incidence risk (0.91%), while gastric cancer had the highest mortality risk (0.35%); (3) Males faced approximately twofold higher risks than females, with East Asia and Mongolia exhibiting the highest regional and national risks, and ages 40–64 representing the high-risk period; (4) Despite overall declining trends, colorectal cancer incidence risk continued to rise. These findings provide evidence-based insights for developing targeted screening strategies.

A new review in Chinese Medical Journal details progress in nanocarrier-based cancer therapy. It analyzes polymeric, lipidic, and other nanoplatforms, their roles in immunotherapy, chemotherapy, radiotherapy, and addresses translation challenges like scalability and biosafety.
