A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...
Researchers have changed the way to look at DNA. They show that DNA is much more than a linear sequence of building blocks; it has a 3D structure that influences the variation of human genome-wide ...
Despite progress in defining functional elements of noncoding DNA, it is still not fully understood. UCLA researchers, using an experiment that elucidated the function of tens of thousands of ...
What happens to the thousands of intestinal cells that have tumour-initiating DNA mutations? A study in mouse models shows that most are eliminated by strong negative selection, but those that survive ...
A single genetic mutation can lead to completely different diseases, depending on the time and location at which the mutation occurs. This finding emerged from the PhD study conducted by Rocio ...
A man sits outside and holds a slim menthol cigarette between his fingers. Close-up with focus on the cigarette. The study provided a comprehensive examination of how lifestyle and environmental ...

This rare mutation wipes brain cells, and the trigger is finally known
A vanishingly rare genetic glitch in a single enzyme can erase a newborn’s brain cells in a matter of weeks, leaving doctors ...
Scientists have revealed parts of the genome that are especially vulnerable to mutations that occur very early on in development. These areas are in the initial portions of genes, where the cell tends ...
