Latest Biology & Health News

The complete guide to biology in 2026: cells and genetics, evolution, the human body, neuroscience, disease, immune systems, and the future of genetic engineering.

Epigenetic clocks estimate aspects of biological aging from DNA-methylation patterns. Learn how they are built, what age acceleration means, and why a biomarker is not a personal diagnosis or a proven aging intervention.

Liquid biopsy analyzes tumor-related material in body fluids. Learn what ctDNA, circulating tumor cells and extracellular vesicles can reveal, and why blood tests do not universally replace tissue biopsy.

Organoids are three-dimensional cell models that reproduce selected features of organs. Learn how they are made, what they reveal, and why they do not equal miniature complete human organs.

Personalized cancer vaccines are experimental immunotherapies designed around tumor-specific markers. Learn how neoantigens are selected, how mRNA and peptide platforms work, and why clinical-trial evidence matters.

Single-cell RNA sequencing measures gene transcripts across individual cells rather than averaging an entire tissue. Learn the laboratory workflow, computational analysis and limitations of the method.
