For decades, biologists have known that the instructions for life are written in DNA, yet the vast majority of those letters seemed to sit in the dark, doing little that was obvious. Now a new ...

Almost 1,500 genes have been implicated in intellectual disabilities; yet for most people with such disabilities, genetic causes remain unknown. Perhaps this is in part because geneticists have been ...

We tend to think of the DNA strands that contain our genetic code as consistent, stable units. But in reality, the cells that ...

Researchers at the Icahn School of Medicine at Mount Sinai, and collaborators at the University of Bristol, KU Leuven, and the NIHR BioResource, have identified a neurodevelopmental disorder, caused ...

Scientists cannot reliably predict whether an individual carrying certain gene variants will eventually end up obese. Put ...

Researchers at the Icahn School of Medicine at Mount Sinai and others have identified a neurodevelopmental disorder, caused by mutations in a single gene, that affects tens of thousands of people ...

Cells are defined by the genes they express. In human cells, there are thousands of different protein coding genes, and the expression of those genes is carefully orchestrated and controlled by a ...

Researchers have revealed that so-called ‘junk DNA’ contains powerful switches that help control brain cells linked to Alzheimer’s disease. When people picture DNA, they often imagine a set of genes ...

Most hypotheses suggest that earlier forms of life had partial genetic codes and used fewer than 20 amino acids. To test these hypotheses, a team from Columbia and Harvard decided to see if they could ...
