Life’s most indispensable molecules are not the serene, unchanging fixtures they might appear to be. Even the proteins that ...

Scientists studying thousands of rats discovered that gut bacteria are shaped by both personal genetics and the genetics of ...

When related animals produce offspring, the young can be affected by physical abnormalities and health problems. We explain why.

In genetics, scientists must analyze the genomes of millions, if not billions, of people, each carrying millions of variants. It’s an unfathomable amount of data. Which leads us to another central ...

The team’s working hypothesis is that heifers demonstrating moderate forage intake with acceptable growth will ultimately become more forage-efficient cows. Simply put, they define an efficient cow as ...

Humans were isolated in southern Africa for about 100,000 years, which caused them to "fall outside the range of genetic variation" seen in modern-day people, a new genetic study reveals. The finding ...

A groundbreaking DNA study has unveiled a hidden chapter in human evolution, revealing that all modern humans evolved from two ancient and distinct groups. This research, published in March 2025, ...

Summary: Using full genome sequencing data from more than 347,000 individuals, researchers quantified how much genetic differences explain human traits such as height, body mass index, fertility, and ...

Imagine autism not as a single puzzle, but as a gallery of mosaics, each piece shaped by different traits, genes, and life experiences. Scientists have long known the condition is complex, but ...

Rare genetic traits are features that are uncommon within the general population. They can lead to different observable features or to rare physical abilities. Rare genetic traits are typically ...

Structural variants (SVs) are alterations in the DNA sequence that involve large-scale changes, typically longer than 50 base pairs. Advances in long-read sequencing have significantly increased ...

In a pair of papers, scientists greatly expanded our catalog of known genomic variation among humans. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...
