In the Nucleus, Genes’ Activity Might Depend on Their Location
Using a new CRISPR-based technique, researchers are examining how the position of DNA within the nucleus affects gene expression and cell function.
‘Broadband’ Networks of Viruses May Help Bacteria Evolve Faster
A newly discovered mechanism may enable viruses to shuttle genes between bacteria 1,000 times as often as was thought — making them a major force in those cells’ evolution.
Unexpected Diversity Found in 16 New Lab Mouse Genomes
The availability of 16 new mouse genomes will help accelerate research into the genetic underpinnings of human traits and diseases.
The Elusive Calculus of Insects’ Altruism and Kin Selection
How the ultra-cooperative behavior of ants, bees and other social insects could have evolved continues to challenge formal analysis. But a new theory about hedging bets against nature’s unpredictability may change the math and shift the debate.
