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....
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...
Structures of apo Cas12a and its complex with crRNA and DNA reveal the dynamics of ternary complex formation and target DNA cleavage.

Unsigned Magnetic Flux as a Proxy for Radial-velocity Variations in Sun-like Stars
RD Haywood, TW Milbourne, SH Saar, A Mortier, D Phillips, D Charbonneau, AC Cameron, HM Cegla, N Meunier, MLP Iii
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...

The Eigenvalues-Based Entropy and Spectrum of the Directed Cycles
The directed cycles form a foundational structure within a network model. By analyzing the in-degree characteristic polynomial of three kinds of matrices of the directed cycles, the authors obtain the eigenvalues of the...

Annexin 1 Is a Component of eATP-Induced Cytosolic Calcium Elevation in Arabidopsis thaliana Roots
Amirah Mohammad-Sidik, Jian Sun, Ryoung Shin, Zhizhong Song, Youzheng Ning, Elsa Matthus, Katie A. Wilkins, Julia M. Davies
Jan 07, 2021
Extracellular ATP (eATP) has long been established in animals as an important signalling molecule but this is less understood in plants. The identification of Arabidopsis thaliana DORN1 (Does Not Respond to Nucleotides) as the...

Coexistence of plastic and partially diffusive phases in a helium-methane compound.
Hao Gao, Cong Liu, Andreas Hermann, Richard Needs, Christopher Pickard, Hui-Tian Wang, Dingyu Xing, Jian Sun
Apr 08, 2020
Helium and methane are major components of giant icy planets and are abundant in the universe. However, helium is the most inert element in the periodic table and methane is one of the most hydrophobic molecules, thus whether...
High strength mullite-bond SiC porous ceramics fabricated by digital light processing
Jian Sun, Jingde Zhang, Xu Zhang, Zihe Li, Jianzhang Li, Sijie Wei, Weibin Zhang, Weili Wang, Guifang Han
Jan 31, 2024
Fabricating SiC ceramics via the digital light processing (DLP) technology is of great challenge due to strong light absorption and high refractive index of deep-colored SiC powders, which highly differ from those of resin...
Water-stable porous Al24 Archimedean solids for removal of trace iodine.
