Math Reveals the Secrets of Cells’ Feedback Circuitry
Maintaining perfect stability through negative feedback is a basic element of electrical circuitry, but it’s been a mystery how cells could do it — until now.
The Body’s Clock Offers a Rhythmic Target to Viruses
Viruses and other parasites may sync with their host’s biological clock — or reset it — to gain an advantage.
Theorists Debate How ‘Neutral’ Evolution Really Is
For 50 years, evolutionary theory has emphasized the importance of neutral mutations rather than adaptive ones at the level of DNA. Real genomic data challenges that assumption.
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.
