The male reproductive system serves as a hotspot for the emergence of new genes. Perhaps that explains why more new mutations are inherited from fathers than from mothers. It doesn’t, however, clarify ...

As a psychiatric disorder with onset in adulthood, schizophrenia is thought to be triggered by some combination of environmental factors and genetics, although the exact cause is still not fully ...

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 ...

Genetic disorders can occur due to mutations in one gene (monogenic), multiple genes (multifactorial inheritance), and mutation in one or more chromosomes. Point mutations are where one nucleotide in ...

The influenza (flu) virus is constantly undergoing a process of evolution and adaptation through acquiring new mutations. Scientists at St. Jude Children's Research Hospital have added a new layer of ...

Schizophrenia (SCZ) is a psychiatric disorder with onset in adulthood, and is thought to be triggered by some combination of environmental factors and genetics. However, the exact cause of the ...

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 ...

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 ...

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 ...
