Watching flies fly may not seem like high-tech science, but for researchers using the Western Hemispheres most brilliant X-rays, located at the Advanced Photon Source at the U.S. Department of Energys Argonne National Laboratory, it not only helps explain how insects fly but also may someday aid in understanding human heart function.
The researchers, from the Illinois Institute of Technology (IIT), Caltech and the University of Vermont, merged two distinct technologies, intense X-ray beams and electronic flight simulators, to study how insect muscles can generate such extraordinary levels of power. The results are published in the British journal Nature today.
Lead researcher Tom Irving of IIT said that the research has widespread implications. “Flying insects are among the most successful species in the animal kingdom. The ways in which the wing muscles in these insects generate enough power for flight is not completely understood. Insect muscles differ from animal muscles in that they do not need a nerve impulse for every contraction but instead are activated by stretch. The means by which these ‘stretch-activated muscles are turned on and off at high speed — one wing beat takes 5/1000th of a second — has been a mystery.”

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
