For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

Scientists have developed a theoretical model that uncovers the dual role of polyploidy -- organisms carrying extra genome copies -- in evolution. Their findings reveal that polyploidy can stabilize ...

ANN ARBOR—For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ...

When people donate blood, stem cells in the bone marrow make new blood cells to replace what was lost. This stress can drive the selection of certain clones—groups of blood cells with a slightly ...

IN THE POPULAR imagination, cancer starts with a mutation in the DNA of a normal cell. That mutation allows the cell to multiply uncontrollably, circumventing the body’s usual quality-control checks.

Researchers at the Francis Crick Institute have identified genetic changes in blood stem cells from frequent blood donors that support the production of new, non-cancerous cells. Understanding the ...

New research from the University of Kansas shows a "risk gene" linked to higher odds of developing autoimmune diseases such ...
