Geneticists Light Up Debate on Salmon Conservation
Christie Wilcox, PhD | Feb 1, 2023 | 10+ min read
Splitting Chinook salmon into two groups based on their DNA could aid conservation efforts. But some researchers argue that this would be a misuse of the data.

Certain stretches of DNA that regulate gene expression have evolved differently from protein-coding genes.
Conserved Chromatin?
Ed Yong | Dec 9, 2012 | 3 min read
Archaea packages DNA around histones in a similar way to eukaryotes, suggesting that fitting a large genome into a small space was not the original role of chromatin.

Rapidly Dividing Bacteria Coordinate Gene Expression and Replication
Kamal Nahas, PhD | Mar 15, 2024 | 4 min read
E. coli divides faster than it can replicate its genome, while simultaneously expressing its genes. Scientists recently revealed the intricate molecular coordination that makes this possible.
Insights for Conservation
A. J. S. Rayl | Jul 21, 2002 | 2 min read
Like some coevolutionary SWAT team, John Thompson, Bradley Cunningham, and colleagues have headed out every spring and summer for the last decade to the wilds of western Idaho and bordering areas in Oregon and Washington to camp out and infiltrate the world of the prairie starflower, Lithophragma parviflorum, and a little gray moth known as Greya politella. Now, their published rare case study in coevolution describes how the two species have coevolved in a variety of habitats, from open grass
