A ‘Lobby’ Where a Molecule Mob Tells Genes What to Do
Highly repetitive regions of junk DNA may be the key to a newly discovered mechanism for gene regulation.
In Our Cellular Clocks, She’s Found a Lifetime of Discoveries
For decades, Carrie Partch has led pioneering structural research on the protein clockwork that keeps time for our circadian rhythm. Is time still on her side?
Even Synthetic Life Forms With a Tiny Genome Can Evolve
By watching “minimal” cells regain the fitness they lost, researchers are testing whether a genome can be too simple to evolve.
Selfish, Virus-Like DNA Can Carry Genes Between Species
Genetic elements called Mavericks that have some viral features could be responsible for the large-scale smuggling of DNA between species.
A Mutation Turned Ants Into Parasites in One Generation
A new genetics study of ant “social parasites” shows how complex sets of features can emerge rapidly and potentially split species.
Animal Mutation Rates Reveal Traits That Speed Evolution
The first large-scale comparison of mutation rates gives insights into how quickly species can evolve.
How a DNA ‘Parasite’ May Have Fragmented Our Genes
A novel type of “jumping gene” may explain why the genomes of complex cells aren’t all equally stuffed with noncoding sequences.
The Cause of Depression Is Probably Not What You Think
Depression has often been blamed on low levels of serotonin in the brain. That answer is insufficient, but alternatives are coming into view and changing our understanding of the disease.
