Muscle-Repair Defect Underlies Two Muscular Dystrophies

A protein defective in two types of muscular dystrophy also appears to be important in repairing damaged muscle, according to Howard Hughes Medical Institute researchers at the University of Iowa College of Medicine. The discovery reveals the first known component of the machinery that repairs the damaged membrane in a muscle fiber. Further studies of this and related proteins could lead to a better understanding of disorders that affect cardiac and skeletal muscles.

Researchers create highest resolution optical image ever

Researchers at the University of Rochester have created the highest resolution optical image ever, revealing structures as small as carbon nanotubes just a few billionths of an inch across. The new method should open the door to previously inaccessible chemical and structural information in samples as small as the proteins embedded in a cell’s membrane. The research appears in today’s issue of Physical Review Letters.
