Accelerating the tempo of the segmentation clock by reducing the number of introns in the Hes7 gene
Somites, precursors for the segmental structures such as the vertebral column, ribs and skeletal muscles, form periodically by segmentation of the rostral parts of the presomitic mesoderm (PSM). This periodic ...

Lizard tails detach at a biological 'dotted line'
Like sheets of paper marked with perforated lines, gecko tails have unique structural marks that help them sever their tails to make a quick getaway. Though voluntarily shedding a body part in this manner ...

Six degrees of inclination
(Phys.org)—Stay in a tilted bed for weeks with your head at the lower end and your body starts to change as if it were ageing prematurely or living in space. Twelve volunteers in ESA's bedrest study are ...

Locating muscle proteins: Scientists bring the basis of muscle movement into sharper focus
Muscle contraction and many other movement processes are controlled by the interplay between myosin and actin filaments. Two further proteins, tropomyosin and troponin, regulate how myosin binds to actin. ...
