Clinical research: Mice model Rett syndrome’s heart symptoms

by  /  10 February 2012

Mice engineered to carry a Rett syndrome mutation only in neurons are prone to an irregular heartbeat that can lead to sudden death, according to a study published 14 December in Science Translational Medicine.

Microscope reveals nanoscale detail in live mouse brains

by  /  8 February 2012

A new microscope allows researchers to capture the movement of tiny signal-receiving branches in the brains of adult mice at the nanoscale level. The results were published 3 February in Science.

Clinical research: Two compounds treat Rett syndrome in mice

by  /  1 February 2012

Two compounds that enhance the activity of BDNF, a protein needed for the growth of neurons, improve motor skills in mouse models of Rett syndrome and increase the mice’s lifespan.
