What's up in
Interest in a powerful DNA editing tool called CRISPR has revealed that bacteria are far more sophisticated than anyone imagined.
Scientists have begun to decipher the most difficult-to-read parts of the genome — the parts that don’t code for proteins. The new work reveals how errors in these genetic instructions can lead to disease.
A massive statistical study suggests that even though genetic changes happen at random, the final evolutionary outcome — fitness — is predictable.
Our bodies are a genetic patchwork, possessing variation from cell to cell. Is that a good thing?
Despite swapping DNA through interbreeding, butterflies and other animals can maintain distinct species.
An insight borrowed from computer science suggests that evolution values both fitness and diversity.
By comparing the genomes of social and solitary bees, scientists hope to uncover the basis for communal behavior.
Some organisms respond to stress by driving up their mutation rate. Are they evolving specific mechanisms to enhance evolution in times of crisis?
Mysterious episodes of genetic duplication in our great ape ancestors may have paved the way for human evolution.
