Understanding how muscle cells form is crucial to developing new treatments for diseases such as muscular dystrophy and to treating muscle injuries. However, while scientists have focused on muscle cells in culture, they know little about how muscle cells form in a developing embryo.
In this months issue of the journal Developmental Cell, Clarissa Henry, assistant professor in the University of Maine Dept. of Biological Sciences, reports findings from a study of muscle cell development in zebrafish embryos. Looking at the formation of two types of muscle fibers, Henry and co-author Sharon L. Amacher of the University of California, Berkeley, describe a process regulated by a gene known as Hedgehog.
The article is titled "Zebrafish Slow Muscle Cell Migration Induces a Wave of Fast Muscle Morphogenesis." It is based on research at the University of California, Berkeley where Henry was a post-doctoral scientist before coming to UMaine.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
