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

Trying to see them move is like trying to watch a soccer game taking place on the moon. Now, with DNA origami helicopters, researchers have captured the first recorded rotational steps of a molecular motor as it moved from one DNA base pair to another.

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.

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.

In order to move beyond the exfoliation-based fabrication of such devices, it will be necessary to integrate hBN growth into existing, mature epitaxial platforms. In this paper, the authors utilize ultra-high (>1600 degrees Celsius) temperature to realize the MBE synthesis of few-nanometer films of smooth, layered hBN on conventional sapphire substrates. These films additionally demonstrate a rotational alignment to the substrate, demonstrating an influence of the substrate on the growth of two-dimensional crystalline layers.
