20:55 ScienceDaily.comDNA origami joins forces with molecular motors to build nanoscale machines

For decades, researchers have chased ways to study biological machines.

Zebrafish are a highly regenerative species, capable of completely regrowing lost heart tissue. This is not the case in mammals, where the heart regenerates very poorly, with injury leading to scar tissue and loss of function. Thus researchers are exploring the mechanisms of regeneration in zebrafish and other highly regenerative species, such as salamanders, in search of important differences that might become the basis for regenerative therapies. The research here is an example of this sort of work. In any case where trigger mechanisms for regeneration are better mapped, there is the possibility that regeneration might be enhanced via intervention at one of the triggers. Heart muscle cells called cardiomyocytes hold on to the capacity to reprogram themselves and alter their fate in response to […]

Author(s): Ai Ikeda, Yoshiharu Krockenberger, and Hideki Yamamoto Infinite-layer CaCuO2 is an isolated essential block of high-temperature superconducting cuprates while superconductivity in this phase remains elusive. Using molecular beam epitaxy equipped with an atomic oxygen source, the authors present the growth of single crystalline electron-doped infinite-layer Ca1−xRxCuO2 (R = La3+, Nd3+, and Ce4+) thin films. The R substitution significantly enhances the coherent crystal volume and the electronic conductivity. Traces of superconductivity are observed for the Nd substitution of 0.06. Microscopic defects limit the electronic transport of the CuO2 planes, thus the suppression of superconductivity.
