A study published in the Journal of Bioresources and Bioproducts investigates how drying temperatures affect sulfoethylated kraft lignin (SEKL), a sulfonated derivative with applications in textiles, construction, and wastewater treatment. Using nuclear magnetic resonance, XPS, and chromatography, researchers revealed that freeze-drying maintains maximum solubility, charge density, and sulfonic acid group content. In contrast, oven drying induces alkylation and hydrolysis reactions that reduce functionality. The findings highlight the importance of optimizing drying conditions to tailor lignin properties for industrial applications.

Hafnium oxide (HfO₂) is a promising material for advanced semiconductors, but it is also known for its challenging etching properties. A group of researchers from Japan and Taiwan has successfully etched HfO₂ films with atomic-level precision. This process was performed without the use of halogen gases, which are often highly toxic and may act as greenhouse gases.

Do you think that Spotify's suggestions for new music becomes stranger all the time? It may be because of you. In a unique study with researchers from University of Gothenburg, 15 years of listening data shows that musical taste becomes more refined with age.

A new Genomic Press Interview explores how Professor Gerhard Andersson revolutionized psychological treatment delivery worldwide through internet-delivered cognitive behavioral therapy. The Swedish researcher, with over 900 publications and recognition as his country's most cited psychologist, discusses transforming a student's "crazy idea" about online headache treatment into evidence-based digital interventions now integrated into routine healthcare. His work demonstrates that therapist-guided online treatments match traditional therapy effectiveness while dramatically expanding access to mental health services globally.

Jay Tiley, head of the Materials Structures and Processing Section in the Materials Science and Technology Division at Oak Ridge National Laboratory, has received the 2026 Materials Processing and Manufacturing Division Distinguished Scientist award from The Minerals, Metals and Materials Society.

From Japan to the world—scientific innovation and collaboration aimed at solving global challenges will take center stage at the Science Summit, held alongside the 80th United Nations General Assembly from September 9 to 26, 2025. In response to a call from the Okinawa Institute of Science and Technology (OIST), eight Japanese institutions will present six official programs at the summit. These sessions will feature a diverse range of speakers—from PhD students and university presidents to medical professionals, scientists, and engineers—addressing topics such as food and water security, rare and common diseases, inclusive education, and research ethics.
