Modern biology sits at the intersection of computation, chemistry, and medicine. This hub covers genomics, gene editing technologies like CRISPR, synthetic biology, evolutionary biology, and the science informing precision medicine.

Molecules come in left- and right-handed forms, and biology responds to only one. How chemists learned to make the form they want, and why it won a Nobel.

The 2026 medicine Nobel went to optogenetics — switching individual neurons on and off with light, using a protein borrowed from a green alga.

Synthetic biology treats DNA as something you write, not just something you edit. How the design–build–test cycle works, the cell built with only 473 genes, what the field has actually delivered — and the 149 genes nobody can explain.

An mRNA vaccine doesn't deliver a drug — it delivers instructions your own cells read once and throw away. Here's what really happens, and why the same trick now targets cancer.

CRISPR lets scientists rewrite DNA with startling precision — and it's already curing a genetic disease. Here's how gene editing works, in plain English.
CRISPR-Cas9 is a gene-editing technology that allows scientists to precisely modify DNA sequences in living cells. It has applications in medicine, agriculture, and fundamental research.
Gene editing is the deliberate alteration of an organism's DNA — adding, removing, or changing specific sequences. Modern tools like CRISPR make this precise and relatively cheap, enabling everything from disease research to crops that resist drought.
Synthetic biology is the design and engineering of new biological parts, systems, or organisms — for example, reprogramming microbes to produce medicines or materials. It combines biology with engineering principles and often relies on gene-editing tools.
