Metabolic regulation at the maternal-embryo interface is essential for successful embryo implantation, yet its dynamics in humans remain poorly understood because of ethical and technical constraints. Researchers established a physiologically relevant maternal-embryo interaction model by co-culturing human blastoids with 3D endometrial assembloids, enabling analysis of metabolic changes during the implantation window. The study provides a systematic view of metabolic dynamics at the human maternal-embryo interface, identifies lipid remodeling and arachidonic acid (ARA) metabolism as key regulators of maternal and embryonic responses during implantation, and offers a mechanistic basis for diagnosis and metabolic intervention strategies in implantation failure.

Magnetic field sensors are found in automobiles, smartphones and security systems. But many of these components are made of materials that are neither health- nor environment-friendly and are complex to produce. In Nature Communications (DOI: 10.1038/s41467-026-71077-9), an international team led by researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has now presented a sustainable alternative: printed sensors composed of iron, iron oxide and bio-based materials like cellulose and starch. They measure magnetic fields reliably, are resource-saving to produce and can purportedly be disposed of safely or recycled after use.

Researchers at the Faculty of Information Technology at the University of Jyväskylä have used artificial intelligence to speed up the analysis of colorectal cancer samples and predict the functioning of the cells’ DNA repair mechanism. The AI model's analysis can help shorten diagnosis times, reduce costs, and improve the analysis's accuracy. The research was conducted in collaboration with the Central Finland Welfare Region and is co-funded by the European Union.

An Osaka Metropolitan University-led research team found that deficiencies in vitamin B₁₂ and folate lead to elevated homocysteine levels, which may be linked to fatigue and decreased motivation.

Atopic dermatitis (AD), the most common form of eczema, impacts patients’ life trajectories beyond the physical scars. A novel study shows that adults with AD, particularly those with childhood onset, report significantly greater limitations in their educational and professional choices, with up to 38% of childhood-onset patients reporting career restrictions and more than 36% reporting constrained study choices, compared to individuals whose disease began in adulthood. The findings of the new study in the Journal of Investigative Dermatology (JID), published by Elsevier, provide a scientific basis for more comprehensive, early, and multidimensional care that goes beyond symptom control for patients with AD.

A research team led by Dr. Hwi-Won Seo and Dr. Choong-Min Ryu at the Infectious Disease Research Center of the Korea Research Institute of Bioscience and Biotechnology (KRIBB), in collaboration with Prof. Doo-Jin Kim at Chungbuk National University, has now identified a specific gut microbial group that can dramatically worsen sepsis by excessively sensitizing immune cells.
