The human stomach operates in an environment with a lumen pH between 1 and 3, yet its own tissues remain intact. This resilience comes from a multilayered defense system: a mucus-bicarbonate barrier ...

A ketogenic diet—one that is high in fat and extremely low in carbohydrates—has been known for decades to reduce seizures in some epilepsy patients. But how the highly restrictive diet achieves these ...

Cells and tissues have a multitude of methods for intercellular communication. Nanoscale assemblies that transfer proteins and RNAs between cells are known, but the impacts of external additions or ...

A new study describes a key molecular mechanism that explains how cells exchange information through extracellular vesicles (EVs), small particles with great therapeutic potential. The results, ...

Compare the number, radius, cross-sectional area, and blood flow of blood vessels. The linear velocity of blood is lowest in the capillary because of its largest total cross-sectional area. In ...

The interaction between Hertwig's epithelial root sheath (HERS) and surrounding mesenchymal cells is crucial for root dentin formation. HERS influences tooth root development and odontoblast ...

A research team led by Professors Yixuan Wang and Shaorong Gao from the School of Life Sciences and Technology at Tongji University has made significant progress in understanding early human embryonic ...

Water makes up around 60% of the human body. More than half of this water is inside the cells that make up organs and tissues, and much of the remaining water flows in the spaces between cells. MIT ...

A new technical paper titled “Josephson Junctions in the Age of Quantum Discovery” was published by researchers at Lawrence Berkeley National Laboratory, UC Berkeley, Gwangju Institute of Science and ...

Researchers at Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, demonstrate a novel approach for nanoscopic profiling of small extracellular vesicles (sEVs) using high-speed atomic ...
