Big Picture Science for July 06, 2026: CRISPR Mosquitoes

A stylized DNA double helix made of blue spheres against a red background. The DNA strand is shown diagonally, with one section broken so that a short cluster of red spheres appears to be detaching from the helix. The background is mostly red and black with soft, out-of-focus circular shapes that suggest cells or viruses but are not clearly defined. The overall image gives a scientific, microscopic impression, focusing on the DNA break and the separated red fragment.









Big Picture Science: CRISPR Mosquitoes

REPEAT
The powerful gene editing tool CRISPR is already being tested on animal and plant cells. It has even been used on humans. How might this revolutionary tool change our lives? On the one hand, it could cure inherited diseases and rid the world of malaria-spreading mosquitoes. On the other hand, scientists using it are accelerating evolution and introducing novel genetic combinations that could transform our biological landscape in unforeseen ways. We explore the ramifications of this revolutionary technology.
