Researchers Develop DNA Origami Platform for Stable, Secure Molecular Data Storage
Scientists have created DOCS (DNA Origami for Combinatorial data Storage), a new method that encodes information into DNA structures using enzymatic techniques, enabling data storage that is thermostable, biologically replicable, and randomly accessible. The approach addresses limitations of previous DNA storage methods by improving stability and utilizing DNA's natural copying mechanisms. This advancement could enable secure molecular data storage and authentication systems with potential capacity for files up to several hundred kilobytes.
Researchers have introduced DOCS, a DNA origami-based platform that encodes information directly into scaffold molecules through combinatorial enzymatic processes. Unlike earlier DNA storage approaches that relied on DNA hybridization—which has limited stability—DOCS achieves higher thermal stability while maintaining biological cloneability and random data access capabilities. The team demonstrated the platform's versatility by creating a stochastic molecular authentication system alongside the storage functionality. Computer simulations indicate the method could scale to store large files of several hundred kilobytes. The work bridges classical DNA sequence-based storage with DNA nanostructure approaches, offering a more robust and scalable strategy for molecular data storage and security applications.

Study Maps Somatic Mutations in B Cells of Systemic Lupus Erythematosus Patients, Linking Genetic Changes to Disease Progression
Researchers analyzed somatic mutations across B-cell subsets in 35 systemic lupus erythematosus (SLE) patients and found that double-negative B cells accumulated the highest mutational burden. These mutations were associated with disease duration and immunosuppressive therapy rather than disease activity, and some mutations resembled those found in B-cell lymphomas. The findings suggest that chronic immune stimulation and therapeutic pressure drive clonal evolution in autoimmune disease, potentially explaining disease heterogeneity and progression.
Preserving Native Cellulose-Xylan Structure Enables High-Performance Sustainable Nanofibrils
Researchers developed an optimized method to isolate holocellulose nanofibrils (hCNFs) that preserves the native architecture of cellulose and xylan, mimicking the structural design of plant cell walls. The study used multiple plant systems including Arabidopsis mutants and Brassica napus straw to systematically determine how xylan composition and structure affect nanofibril properties. The findings demonstrate that maintaining native cellulose-hemicellulose interactions produces high-performance materials without harsh chemical treatments, offering a sustainable alternative to conventional nanocellulose production.
Study Identifies Galectin-3's Role in Gastric Metaplasia Development Through Cathartocytosis
Researchers found that galectin-3, a protein upregulated in precancerous tissue changes, facilitates a cellular process called cathartocytosis that promotes the development of spasmolytic polypeptide expressing metaplasia (SPEM) in the stomach. Galectin-3 is abnormally expressed alongside sulfated mucins in high-risk precancerous conditions like Barrett's esophagus and intestinal metaplasia. The findings suggest galectin-3 may represent a therapeutic target for preventing progression from normal tissue to metaplastic and potentially cancerous states.
