Scientists have traced a devastating pattern of brain cell loss in a handful of families to a single, ultra-rare mutation that sabotages one of the brain’s key protective enzymes. The discovery not ...

A microscopic flaw in the brain’s cellular scaffolding can shape brain size for life.

A vanishingly rare genetic glitch in a single enzyme can erase a newborn’s brain cells in a matter of weeks, leaving doctors with almost no way to intervene. Researchers have now traced that ...

Geneticists have sought to understand the impact of genetic mutations, and what drives and maintains changes in DNA. Researchers have now reconstructed the evolution of a set of genes, and the ...

Our DNA is compacted and arranged into chromosomes, most of which are shaped like X’s. The ends of the chromosomes arms are ...

The DNA mutations that drive evolution are generally thought to be fairly random, but a new study suggests there’s some order to the chaos. Comparing the genomes of hundreds of plants grown in a lab, ...

A new long-read sequencing technique has helped researchers investigate how DNA mutations arise in a variety of contexts. A collaboration of researchers led by NYU Langone Health and NYU Grossman ...

This produces point mutations in the DNA, which are mostly harmless but can sometimes lead to genetic disorders. In the new study, the Surrey researchers discovered that some of these modifications ...

Although previously thought to be neutral, research in yeast suggests that synonymous point mutations may have strongly nonneutral effects. A group of researchers from the University of Michigan (MI, ...

Banana and plantain are among the world's major food crops, and considered as the poor man's fruit crop in tropical and subtropical countries. The world's total banana and plantain production ranks ...
