Scientists may soon be able to influence muscle formation more easily as a result of research conducted in the National Institute of Arthritis and Musculoskeletal and Skin Diseases’ Laboratory of Muscle Biology. The researchers there and at institutions in California and Italy have found that inhibitors of the enzyme deacetylase can switch the pathway of muscle precursor cells (myoblasts) from simply reproducing themselves to becoming mature cells that form muscle fibers (myotubules).
It has been known for some time that deacetylase prevents the skeletal muscle gene from being expressed, which inhibits myoblasts from forming muscle. The research team has found that under certain conditions, deacetylase inhibitors (DIs) in myoblasts enhance muscle gene expression and muscle fiber formation.
Knowledge of how DIs act against deacetylase is providing important insights on potential ways to correct problems that occur during embryonic muscle development. This research may also lead to methods to induce muscle growth, regeneration and repair in adults.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
