Searching for the origin of muscles
Ulrich Technau from the University of Vienna has addressed the origin of musculature. His analysis reveals for the first time that some central components of muscles of higher animals are much older than previously assumed. These results, now published in the renowned journal Nature, indicate that muscle-like cell contraction originated already very early during animal evolution, while the specialization of basal muscle cell types, such as striated muscles, occurred only later and several times independently. (2012-06-28)

Cardiac and respiratory function supported by abdominal muscles in muscular dystrophy
Using mouse models, researchers found that abdominal muscles may be severely involved in the muscular dystrophy process. The abdominal muscles are important to provide respiratory support when the diaphragm muscle has been damaged by the disease, so that additional abdominal muscle involvement can worsen the respiratory situation considerably. These findings are of great importance for understanding the progression of cardio-respiratory failure in the human disease. (2015-02-26)

One or the other: Why strength training might come at the expense of endurance muscles
The neurotransmitter brain-derived neurotrophic factor (BDNF) acts in the muscle, so that during strength training endurance muscle fiber number is decreased. Researchers at the University of Basel's Biozentrum have more closely investigated this factor, from the group of myokines, and demonstrated that it is produced by the muscle and acts on both muscles and synapses. The results published in PNAS also provide new insights into age-related muscle atrophy. (2019-07-25)
