Axisymmetric dynamo action is possible with anisotropic conductivity

Physical Review Research, 2020
A milestone of dynamo theory is Cowling's theorem, known in its modern form as the impossibility for an axisymmetric velocity field to generate an axisymmetric magnetic field by dynamo action.

Turbulent dynamo in the terrestrial magnetosheath [PDF]

Nature Communications
Dynamo action refers to energy exchange processes through which magnetic fields are generated at the expense of kinetic energy of the plasma flows. Dynamos can generate magnetic fields across scales larger or smaller than the flows themselves.

Universal dynamo paradigm for solar activity, Higgs fields and disasters [PDF]

EPJ Web of Conferences, 2021
There is still a problem of a correct and accurate description of the dynamo and its uses in various fields of physics. To solve this problem, a special and universal representation of dynamo is proposed.

Characterization of Arabidopsis CYP79C1 and CYP79C2 by Glucosinolate Pathway Engineering in Nicotiana benthamiana Shows Substrate Specificity Toward a Range of Aliphatic and Aromatic Amino Acids

Frontiers in Plant Science, 2020
Glucosinolates (GLSs) are amino acid-derived defense compounds characteristic of the Brassicales order. Cytochromes P450s of the CYP79 family are the entry point into the biosynthetic pathway of the GLS core structure and catalyze the conversion of amino

An evolutionarily young defense metabolite influences the root growth of plants via the ancient TOR signaling pathway

eLife, 2017
To optimize fitness a plant should monitor its metabolism to appropriately control growth and defense. Primary metabolism can be measured by the universally conserved TOR (Target of Rapamycin) pathway to balance growth and development with the available ...
