Mice who get less attention from their mothers have more copies of a common retrotransposon in the genomes of their hippocampal neurons.

No two neurons are alike. What does that mean for brain function?

Recent advances in single-cell omics and other techniques are revealing variation at genomic, epigenomic, transcriptomic, and posttranscriptomic levels.

Meet some of the people featured in the March 2015 issue of The Scientist.

How do we age, and can we slow it down?

These mobile genetic elements can wreak havoc on the genome. Researchers are now trying to understand how such activity contributes to the aging process.
