By studying and manipulating heart tissue in the unique low-gravity environment of space, Dr. Arun Sharma’s lab is discovering new ways to protect and repair failing hearts. He was speaking today at the 46th Annual Meeting and Scientific Sessions of the International Society for Heart and Lung Transplantation (ISHLT) in Toronto. Dr. Sharma explained that space is a yin-yang environment that promotes tissue aging and degradation and provides an ideal environment for growing more complex three-dimensional heart tissue and patches from patient-specific stem cells. Heart disease experiments conducted in space with rapid results “In microgravity, the deterioration of cardiovascular conditions…

Researchers at Brown University and their collaborators have developed a new method to measure cell properties. They say this is an important advance because accurately measuring changes in cell elasticity can help better understand diseases, diagnose patient symptoms and provide more accurate prognoses. For example, cancer cells from a tumor typically soften as they become more dangerous and spread more easily, whereas blood diseases such as malaria and sickle cell can harden red blood cells. Mechanical changes at the cellular level are also observed in neurodegenerative, cardiovascular, and chronic inflammatory diseases. As detailed in a study in the journal lab…

New research published in Journal of Sex Research It suggests that the specific words used to describe people in the commercial sex industry shape how the public views them. The findings provide evidence that terms such as ‘sex worker’ and ‘escort’ carry less stigma and are viewed more positively than terms such as ‘prostitute’ and ‘prostitute’. This suggests that changing the language used in the media and legal settings may help reduce bias against these professionals. Researchers conducted this study to better understand the powerful role language plays in shaping social prejudice. “Truth is, this study is very personal to…

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.…
