A study published in the Proceedings of the National Academy of Sciences by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not ...

Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

Two of the traits that set modern humans apart from non-human primates are taller stature and a higher basal metabolic rate. Researchers have identified a genetic variant that contributed to the ...

How do cells know what they should become as the body develops? Biological development depends crucially on spatial patterns: the lines that eventually give rise to segments, organs, or markings like ...

A newly discovered genetic mutation unique to humans may help explain why we are significantly more vulnerable to cancer than our closest evolutionary relatives. Researchers at the University of ...

Modern HIV medicine is based on a common genetic mutation. Now, researchers have traced where and when the mutation arose -- and how it protected our ancestors from ancient diseases. Modern HIV ...

Human cells usually contain two copies of most genes, one of which comes from the mother while the other comes from the father. It's long been thought that usually these two copies, or alleles of ...

What Is the MTHFR Gene Mutation? The MTHFR gene mutation is a variation in the MTHFR gene. This gene normally tells your body how to make the MTHFR protein. You need this protein to process folate, ...

Human semen not only accumulates genetic mutations with age; as the percentage of sperm carrying potentially serious mutations increases, so does the risk of developing diseases in offspring. This is ...

A groundbreaking study published in this week’s issue of PNAS by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not randomly but more ...
