Taking lab mice back to their roots
Lab mice are incredibly useful for biomedical research. But they are also incredibly inbred. A new study shows that bringing wild mouse traits back could help uncover new links between genes and behavior.

HIV hides in growth-promoting genes
The discovery that HIV can trigger infected cells to divide means scientists may need to rethink strategies for treating the virus that causes AIDS.

This rare skull-thickening disease led to a 3-D-printed replacement
A skull implant made with a 3-D printer replaced the 2-inch-thick skull of a Dutch woman with the rare van Buchem disease.

One giant leap for zit-causing microbes
A bacterium that lives on humans and causes acne also hopped to domesticated grapevines and relies on the plant for crucial DNA repairs.

Cancer variants found in ‘neglected’ region of genome
Mutations outside of genes associated with disease in study using data from a thousand people.

The origin of biological clocks
Most of Earth’s creatures keep time with the planet’s day/night cycle. Scientists are still debating how and why the circadian clocks that govern biological timekeeping evolved.
- Genetics
Origin of Tibetans’ high-altitude adaptations found
Mixing genes of two ancestral populations gave modern Tibetans their ability to withstand high altitude.
- Neuroscience
All mice are the same, until they’re not
A new study shows substantial differences in how two closely related mouse strains respond to drugs. It offers new options for linking genes and behavior and may change how scientists think about the similarity of their mouse strains.

Brain chemicals help worms live long and prosper
Serotonin and dopamine accompany long lives in C. elegans worms under caloric restriction.
- Neuroscience
Gene adds wrinkle to brain development
Mutations in the gene GPR56 results in misshapen folds in the brain tied to intellectual and language disabilities.
