Gene

A gene is a unit of heredity in a living organism. It normally resides on a stretch of DNA that codes for a type of protein or for an RNA chain that has a function in the organism. All living things depend on genes, as they specify all proteins and functional RNA chains.

What are Genes?

Deoxyribonucleic acid (DNA) is the chemical information database that carries the complete set of instructions for the cell as to the nature of the proteins produced by it, its life span, maturity, function and death. Genes are the working subunits of DNA. Each gene contains a particular set of instructions, usually coding for a particular protein or for a particular function.

Deep-learning tissue clocks reveal how organs age and leave disease-linked signals in blood

Deep learning applied to more than 25,000 histopathology slides revealed tissue-specific structural signatures of biological aging that tracked telomere attrition, pathology, comorbidity, and molecular changes more closely than chronological age alone.

Sprint exercise sends a very different molecular signal through the body

Sprint-interval exercise triggers a much larger and faster shift in circulating proteins and metabolites than moderate-intensity exercise, revealing distinct patterns of predicted communication between organs. The findings suggest that exercise intensity shapes systemic molecular signaling, with skeletal muscle and adipose tissue emerging as potential source and target tissues linked to cardiometabolic health.
