Is the Sun a Magnet?
DO Gough
Jul 05, 2017
It has been argued (Gough and McIntyre in Nature394, 755, 1998) that the only way for the radiative interior of the Sun to be rotating uniformly in the face of the differentially rotating convection zone is for it to be pervaded...

This article aims to alert the medical community and public health authorities to accumulating evidence on health benefits from sun exposure, which suggests that insufficient sun exposure is a significant public health problem....
Evidence for an iterative module in chain elongation on the azalomycin polyketide synthase.
Hui Hong, Yuhui Sun, Yongjun Zhou, Emily Stephens, Markiyan Samborskyy, Peter F Leadlay
Oct 10, 2018
The assembly-line synthases that produce bacterial polyketide natural products follow a modular paradigm in which each round of chain extension is catalysed by a different set or module of enzymes. Examples of deviation from...

Aug 08, 2022
We estimate disc-averaged RV variations of the Sun over the last magnetic
cycle, from the single Fe I line observed by SDO/HMI, using a physical model
for rotationally modulated magnetic activity that was previously...

Cross-Module Enoylreduction in the Azalomycin F Polyketide Synthase.
Guifa Zhai, Wenyan Wang, Wei Xu, Guo Sun, Chaoqun Hu, Xiangming Wu, Zisong Cong, Liang Deng, Yanrong Shi, Peter F Leadlay, Heng Song, Kui Hong, Zixin Deng, Yuhui Sun
Oct 19, 2020
The colinearity of canonical modular polyketide synthases, which creates a direct link between multienzyme structure and the chemical structure of the biosynthetic end-product, has become a cornerstone of knowledge-based genome...
An Iterative Module in the Azalomycin F Polyketide Synthase Contains a Switchable Enoylreductase Domain.
Wei Xu, Guifa Zhai, Yuanzhen Liu, Yuan Li, Yanrong Shi, Kui Hong, Hui Hong, Peter F Leadlay, Zixin Deng, Yuhui Sun
Sep 05, 2018
Detailed analysis of the modular Type I polyketide synthase (PKS) involved in the biosynthesis of the marginolactone azalomycin F in mangrove Streptomyces sp. 211726 has shown that only nineteen extension modules are required to...
The high-energy Sun - probing the origins of particle acceleration on our nearest star
Abstract As a frequent and energetic particle accelerator, our Sun provides us with an excellent astrophysical laboratory for understanding the fundamental process of particle acceleration. The...
