Tea, made from the Camellia sinensis plant, is one of the most widely consumed beverages in China and globally. Beyond its cultural significance, tea is rich in bioactive compounds such as polyphenols, polysaccharides, caffeine, and especially epigallocatechin gallate (EGCG), a potent antioxidant linked to numerous health benefits.

Ultramicroporous carbon materials with Ångstrom-precise pore engineering offer a transformative solution for separating fluorinated gases like C₃F₆ (fluorinated propylene) and C₃F₈ (fluorinated propane). A team of scientists has synthesized the CO₂-activated porous carbon adsorbents derived from a precursory resin and systematically investigated their molecular sieving behavior for C₃F₆/C₃F₈ mixtures. Through controlled thermal pyrolysis and stepwise CO₂ activation, they tailored ultramicropore size distributions to selectively exclude or admit target molecules. Their work is published in the journal Industrial Chemistry & Materials on 24 Jun 2025.

Long COVID continues to affect millions, with symptoms that mirror those of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). This research highlight reveals that both conditions share common roots in cellular oxidative stress and immune dysfunction, potentially leading to long-term brain damage. It proposes that ME/CFS is a progressive neurodegenerative disorder and could serve as a useful model for understanding brain aging, energy failure, and the lasting neurological effects of viral pandemics.

To address these questions, a research team from Mansoura University, the Agricultural Research Center, and the University of Reading conducted a study in the agricultural provinces of Dakahlia, Giza, and Minya. The study involved 300 farmers using four types of plastic agriculture systems: open-field films, low tunnels, high tunnels, and net houses. Through stratified random sampling and face-to-face interviews, the team analyzed plastic usage characteristics, disposal methods, recycling barriers, and key motivations. The article was recently published in Frontiers of Agricultural Science and Engineering (DOI: 10.15302/J-FASE-2025621).

The world's first thousand-ton-scale ionic liquid-based regenerated cellulose fiber project has officially commenced operations in Henan Province, China. Developed by the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences, the project marks the first large-scale global production of regenerated cellulose fibers using ionic liquids.

This article reviews recent advances in flexible electrochromic (EC) devices for wearable electronics, offering in-depth insights into material innovations, device structures, performance metrics, and practical applications. It also highlights the key challenges and future prospects of flexible EC technologies, aiming to bridge the gap between materials research and real-world implementation in smart wearable systems.

This study systematically investigates the cytotoxicity evolution of protonated carbon nitride toward red blood cells and elucidates its underlying mechanisms, revealing that surface protonation amplifies carbon nitride nanosheet-induced phospholipid extraction and enhances cytotoxicity.

Objective

Colorectal cancer (CRC), a common malignant tumor of the digestive tract, poses a worldwide threat to human health. Methods: This study conducted a narrative literature review to assess and provide perspectives on the evolving understanding of dietary nutrients and one-carbon metabolism in the context of colorectal cancer.

Results

Certain nutrients can serve as precursor (methionine and serine) or cofactor (B vitamins) for one-carbon (1C) units, participating in 1C metabolism through a network of interrelated biochemical pathways that involve the transfer of 1C units. 1C metabolism, in turn, affects tumor cell fate through several mechanisms such as nucleotide synthesis, epigenetic modifications, redox homeostasis, and the interaction with gut microbiota, all of which are implicated in the pathogenesis and progression of CRC.

Conclusions

A deeper understanding of the intricate relationships between the three offers new insights into the mechanism of 1C metabolism in the development of CRC, the role of diet in modulating one-carbon metabolism and potential therapeutic interventions for cancer.
