A new study finds that, in healthy women, some breast cells that otherwise appear normal may contain chromosome abnormalities typically associated with invasive breast cancer. The findings question ...

In a major leap forward for genetic and biomedical research, two scientists at the University of Missouri have developed a powerful new artificial intelligence tool that can predict the 3D shape of ...

Trisomy is a genetic condition characterized by the presence of an extra chromosome. This means that the affected person has three copies of the 21st chromosome instead of two. The most common forms ...

The herpesvirus can manipulate our DNA with far more precision than previously thought. The virus condenses and changes the shape of our genetic material to hijack the host genes needed for ...
