Environmental transmission electron microscopy is used to reveal that mismatch dislocations modulate the interfacial transformation of copper oxide to copper metal in an intermittent manner.
Experiments in mice show that although ketamine has positive reinforcement properties, which are driven by its action on the dopamine system, it does not induce the synaptic plasticity that is typically observed with addiction.
Examination of archaeological pottery residues and modern genes suggest that environmental conditions, subsistence economics and pathogen exposure may explain selection for lactase persistence better than prehistoric consumption of milk.
Experiments and theory show that transmission peak degeneracies near exceptional points in an electromechanical accelerometer can be used to improve the signal-to-noise ratio of the sensor.
The PI3K–PANK4 axis regulates coenzyme A synthesis, the abundance of acetyl-CoA, and CoA-dependent processes such as lipid metabolism, and these regulatory mechanisms coordinate cellular CoA supplies with the demands of hormone and growth-factor-driven or oncogene-driven metabolism and growth.
An alternating stack of a candidate spin liquid and a superconductor shows a spontaneous vortex phase in the superconducting state without magnetism in the normal state. This indicates the presence of unconventional magnetic ordering independent of the superconductor.
