Finding the Origins of Life

Clips from the National Geographic Channel’s TV show, Finding the Origins of Life. Follow along with scientists as they discuss theories on life, evolution, and primordial molecular biology.

Zika Virus Shell

This is a 3D print of the Zika Virus with a digital QRC code base. Green colored proteins chains and yellow active sites demonstrate the complexity and beauty of this dangerous virus. Prints available in multiple sizes (small, medium, and large) through our store. Purchase through the Biologic Models shop and take an extra 10% the medium size molecular model kit.

Glycated Hemoglobin, HbA1c, Biologic Models

Glycated Hemoglobin HbA1c

Sugar attaches to hemoglobin (Hb) and changes the protein’s shape, impairing its function. Learn more about the dangers of high blood sugar and the importance of knowing your HbA1c test scores using 3D reproductions of Glycated Hemoglobin (HbA1c).

PIP4K, Lewis Cantley, Biologic Model

PI4K II Alpha and Beta

Recently, Cornell University commissioned us to create 3D printed models of PIP4K II Alpha and Beta for the purpose of demonstrating PIP4K dimerization.

RSV Fusion F Glycoprotein

The Human Respiratory Syncytial Virus (HSV) is a major cause of lower respiratory tract infection. Deadly to newborn babies, new therapies are being developed to keep infants alive. By understanding how dynamic structural changes in the Fusion F Glycoprotein reveal and hide binding sites, new therapies more effectively target RSV and prevent infection.


This is a 3D print of CRISPR Ca9 is created in full-color sandstone. The model depicts CRISPR (purple) bound to its guide RNA (red) while editing its Target DNA (yellow and green). The subtle color variations in the CRISPR are associated with its bFactor, or atomic temperature. The darker the color, the less the protein moves with a cooler atomic temperature.
