Video: Why study mouse lemurs?

Like humans, mouse lemurs sometimes develop amyloid brain plaques and other Alzheimer's-like symptoms as they age. Because mouse lemurs are primates, they are a closer genetic match to humans than mice or rats are.

Gene enhancers important despite apparent redundancy

Every cell in the body has the same DNA and genes, so a cell's properties and functions are determined by which genes are turned on. That's why it is critical to understand enhancers, short sections of non-coding DNA that ...
