Epigenetics: How Genes Turn On and Off Without Changing DNA
Cells with identical DNA end up wildly different — the answer lies in epigenetics, the chemical marks that switch genes on and off without touching the DNA sequence. Explore DNA methylation, histone modification, and the striking Dutch Hunger Winter case that reshaped how scientists see nature versus nurture.

From fireflies to deep-sea fish, many organisms convert chemical energy directly into light using molecules called luciferin and luciferase. Discover the mechanism behind bioluminescence and its scientific uses.

Below a critical temperature, some materials lose their electrical resistance entirely and expel magnetic fields from their interior. This article covers the discovery of superconductivity, the Meissner effect, the BCS theory of Cooper pairs, and today's applications.
