Human cells have two copies of each chromosome, and this balance is essential for genes to be expressed in the appropriate ...

Amazon mollies don't need a man, and never will. A new study finds they can purge and repair genetic mutations that would otherwise plague a self-cloning species.

A study explains how broken DNA during cell division can trigger chromoanasynthesis when two repair pathways combine, causing ...

Non-invasive prenatal testing (NIPT) is a simple blood test during pregnancy that helps detect rare genetic conditions early, ...

Delayed parenthood intersects with important biological realities. Female fertility begins to decline gradually after the age of 32 and more sharply after 37. By age 40 the chance of natural ...

The Amazon molly reproduces without sex. A genomic copy-and-paste trick called gene conversion may explain how it avoids evolutionary meltdown.

St. Patrick’s Day gets us thinking about all things green — from shamrock decorations to our lawns, which we hope will soon show signs of life.

Doctors explain why women face a higher risk of autoimmune diseases like lupus, rheumatoid arthritis and thyroid disorders, ...

Thin stretches of the human X chromosome look oddly empty when you scan for Neanderthal DNA. Geneticists even have a name for the gaps: “Neanderthal deserts.

An insightful mini-review published in Genomic Psychiatry synthesizes the rapidly expanding landscape of molecular genetic research on common epilepsies, assembling evidence from genome-wide ...

Trained on 9 trillion DNA base pairs from every domain of life, the Evo 2 model can predict disease-causing mutations, identify genomic features and generate entirely new genetic sequences.
