New research published in engineering Ovaclactone (OL) was revealed to be a natural tetracyclic triterpenoid. yellow leafy cortexexerts therapeutic effects on rheumatoid arthritis (RA) by promoting the degradation of acyl-coenzyme A thioesterase 1 (ACOT1) through the ubiquitin-proteasome pathway and restoring unsaturated fatty acid homeostasis. This study reveals the molecular mechanism of OL in RA intervention, identifies ACOT1 as a new potential target for RA treatment, and provides new insights into reprogramming fatty acid metabolism as a therapeutic strategy for RA. In this study, researchers established a complete Freund’s adjuvant (CFA)-induced RA rat model and treated rats with low (50 mg…

East Africa’s Turkana Rift Valley is known for both its rich record of early human fossils and intense volcanic activity caused by plate movement. Scientists now report that the region’s underground crust is much thinner than previously understood, pointing to a long-term breakup of the African continent and offering a new explanation for why so many ancient human remains were preserved there. The survey results are nature communications. Vast cracks formed by the movement of plates The Turkana Rift extends for approximately 500 kilometers across Kenya and Ethiopia and forms part of the larger East African Rift system. This huge…

New research published in engineering We provide mechanistic insights into the glycoengineering of living cells and support the rational design of next-generation adoptive cell therapy (ACT) for B lymphoma, addressing limitations such as high cost and limited antigen specificity in current treatments. Researchers from Peking University and international organizations compared β-galactoside alpha 2,6 sialyltransferase 1 (ST6Gal1)-mediated metabolic glycoengineering (MGE) and chemoenzymatic glycoengineering (CeGE) in NK-92MI cells, focusing on their molecular profiles and multiplexing capabilities. Glycoproteomic analysis revealed content-dependent customization of the NK-92MI glycocalyx. Exogenous ST6Gal1-assisted CeGE showed equivalent or higher ligand transduction efficiency than MGE, with modifications to specific immune…

Research published in engineering identified fucosylated immunoglobulin G (IgG) as a key mediator contributing to age-related adipose tissue dysfunction, providing insight into age-related metabolic disorders and potential therapeutic targets. Researchers from North China University of Science and Technology and Capital Medical University conducted transcriptomic and glycoproteomic analyzes of epididymal white adipose tissue (eWAT) from young and aged mice. RNA-seq results showed significant downregulation of adipogenic genes in aged eWAT, accompanied by increased expression of inflammatory and fibrotic markers, which was verified by quantitative polymerase chain reaction. Comprehensive N- and O-glycoproteomic profiling revealed widespread glycosylation changes in aging adipose tissue and…

Differences in brain connectivity have been linked to several neurodevelopmental disorders, but scientists are still struggling to determine what changes are common or unique to each condition. A new study analyzing brain scans from more than 2,100 people reveals a pattern of disrupted neural connections common to autism, ADHD and schizophrenia. This study also identifies distinct molecular and cellular features of each disease, providing insight into how complex psychiatric disorders arise from overlapping yet distinct biological mechanisms. Neurodevelopmental disorders and psychiatric conditions, such as autism spectrum disorder (ASD), attention-deficit hyperactivity disorder (ADHD), and schizophrenia, are typically studied as separate disorders.…

Postmenopausal women are at increased risk for both osteoporosis and depression, but their common biological basis remains poorly understood and there is no single treatment that effectively addresses both conditions. In a recent study, researchers discovered that a traditional plant extract used in traditional Chinese medicine may act on a common molecular pathway underlying both bone loss and mood disorders, paving the way for treatments that target both conditions simultaneously. For many women, menopause brings more than hormonal changes. Postmenopausal women often face two seemingly unrelated health challenges at the same time: osteoporosis and depression. Both of these symptoms are…

Antibiotic resistance is making it difficult to treat bacterial infections, and new treatment strategies are needed. A new review highlights bacterial extracellular vesicles (BEVs) as promising nanoscale tools that can kill pathogens, block infections, enhance vaccines, and deliver drugs. Researchers have demonstrated how BEVs can be turned into customizable “nanoweapons” by integrating genetic, chemical, and physical engineering. This approach has the potential to reshape infectious disease treatment by enabling safer, more targeted, and more effective alternatives to traditional antibiotics. Bacterial infections remain a major global health challenge, killing millions of people each year and becoming increasingly resistant to conventional treatments.…

Mental disorders affect millions of people worldwide, but their diagnosis still relies on clinical observations rather than standard biological tests. In an attempt to identify reliable biomarkers, Chinese scientists have now launched the Brain-Gut Health Initiative. This is a large-scale longitudinal study combining neuroimaging, electrophysiology, microbiome sequencing, blood biomarkers, and clinical assessments across major psychiatric disorders. The findings reveal coordinated changes associated with gut microbes, brain networks, and symptoms, supporting the development of AI-assisted diagnostics and personalized treatments. Mental illnesses such as schizophrenia, depression, and bipolar disorder affect approximately one in seven people worldwide. These diseases pose a major and…

A large study led by researchers at Children’s Hospital of Philadelphia, Nemours Children’s Health Hospital, and Children’s National Hospital, and involving a broad network of medical centers across the United States and abroad, found that different types of crystalloid resuscitation were equally effective in preventing the most serious kidney adverse events after treatment of pediatric patients with suspected septic shock. The results of this large-scale clinical trial are detailed in a study published today. New England Medical Journal and presented at the Pediatric Society of America (PAS) conference in Boston. Sepsis is a life-threatening reaction to infection that causes organ…

People who experience severe infections treated in hospital have an increased risk of developing dementia later in life, but this association operates independently of other underlying conditions. Researchers reached this conclusion by analyzing the vast electronic medical records of Finnish citizens. The research results were published in a magazine PLOS medicine. Medical experts have long observed a link between infectious diseases and cognitive decline. Proposed explanations revolve around how the immune system interacts with the central nervous system. Severe infections cause widespread inflammation throughout the body. This persistent inflammation can affect the blood-brain barrier, a dense cell layer that protects…
