01 Biology in 3D · new every week

The great world inside you.

Trillions of cells are at work in you right now. Proteins walk, tiny motors spin, DNA is read and copied without a break. We build it all in real 3D, from published science, so you can see it.

03 Shorts

One fact. Under a minute.

05 How we make it

Wonder, earned by facts.

Never hype, never health advice. Confident about what is known, honest about what is not.

  1. 01

    Real shapes

    Proteins are built from Protein Data Bank structures, one bead per amino acid. Cells follow microscopy. Real micrographs keep their own colours and their credit.

  2. 02

    Every fact sourced

    Every number in a video comes from published research and is listed with a link. When sources disagree, we say the range.

  3. 03

    Honest labels

    A small badge on every 3D shot says what you are looking at: a magnified model, something built from real data, or an explainer drawing.

New every week

Biology you can see.

Four-minute explainers and one-fact Shorts about the machines that keep you alive. Built in real 3D, checked against published research.
