A new solution to the prisoner’s dilemma, a classic game theory scenario, has created new puzzles in evolutionary biology.
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.
All life on Earth is made of molecules that twist in the same direction. New research reveals that this may not always have been so.
Microscopic creatures called bdelloid rotifers have thrived without mating for millions of years. How they did it could reveal why sex is so essential for almost everyone else.
The 2014 Nobel Prize in Physiology or Medicine was awarded to three researchers who discovered how the brain navigates the world. Their work may also help illuminate how the mind stores memories.
A study of diverse colonies of spiders supports a controversial idea in evolution — that natural selection can act on communities as well as on individuals.
The movement of lizards around the Caribbean is forcing researchers to account for human activity in even their most basic ecological models.
A massive statistical study suggests that even though genetic changes happen at random, the final evolutionary outcome — fitness — is predictable.
Despite swapping DNA through interbreeding, butterflies and other animals can maintain distinct species.
