Ultrahigh-field 67Zn NMR reveals short-range disorder in zeolitic imidazolate framework glasses
The structure of melt-quenched zeolitic imidazole framework (ZIF) glasses can provide insights into their glass-formation mechanism. We directly detected short-range disorder in ZIF glasses using ultrahigh-field zinc-67 solid-state nuclear magnetic resonance spectroscopy. Two distinct Zn sites characteristic of the parent crystals transformed upon melting into a single tetrahedral site with a broad distribution of structural parameters. Moreover, the ligand chemistry in ZIFs appeared to have no controlling effect on the short-range disorder, although the former affected their phase-transition behavior. These findings revea...

New research finds infant cereal consumption is associated with improved nutrient intake
(Pollock Communications) An investigation of infant feeding patterns found infants and toddlers consuming baby cereal, such as rice cereal, had higher intakes of key nutrients of concern, such as calcium, magnesium, iron, zinc and vitamin E. The study illustrates the importance of rice baby cereal in the diets of infants and toddlers in achieving proper nutrition. (Source: EurekAlert! - Medicine and Health)

Scientists propose nanoparticles that can treat cancer with magnetic fluid hyperthermia
(ITMO University) A group of Russian scientists have synthesized manganese-zinc ferrite nanoparticles that can potentially be used in cancer treatment. Due to their unique magnetic properties, the particles can serve as deactivators of affected cells while having almost no negative impact on healthy tissues. The results have been published in the Journal of Sol-Gel Science and Technology. (Source: EurekAlert! - Cancer)

ZGLP1 is a determinant for the oogenic fate in mice
Sex determination of germ cells is vital to creating the sexual dichotomy of germ cell development, thereby ensuring sexual reproduction. However, the underlying mechanisms remain unclear. Here, we show that ZGLP1, a conserved transcriptional regulator with GATA-like zinc fingers, determines the oogenic fate in mice. ZGLP1 acts downstream of bone morphogenetic protein, but not retinoic acid (RA), and is essential for the oogenic program and meiotic entry. ZGLP1 overexpression induces differentiation of in vitro primordial germ cell–like cells (PGCLCs) into fetal oocytes by activating the oogenic programs repressed by...

Reconstructing the diet of fossil vertebrates
(Max Planck Institute for Evolutionary Anthropology) Paleodietary studies of the fossil record are impeded by a lack of reliable and unequivocal tracers. Scientists from the MPI for Evolutionary Anthropology, the MPI for Chemistry and the Johannes Gutenberg University (JGU) in Mainz have now tested a new method, the isotope analysis of zinc isotopes from the tooth enamel of fossil mammals, and found it to be well suited to expand our knowledge about the diets of fossil humans and other Pleistocene mammals.

Pulses for a Sustainable Future
By Zoltán KálmánROME, Feb 10 2020 (IPS) Reducing poverty and inequalities, eliminating hunger and all forms of malnutrition and achieve food insecurity for all – these are some of the most important objectives of the Sustainable Development Goals. Still, the rate of poverty and inequalities is increasing and over 820 million people are going hungry. In addition, 2 billion people in the world are food insecure with great risk of malnutrition and poor health. This alarming situation is further aggravated by current trends such as the rate of population growth, impacts of climate change, loss of biodiversity, soil degrad...

Putting a finger on plant stress response
(University of Tsukuba) Researchers from the University of Tsukuba have found that a PHD zinc finger-like domain in SUMO E3 ligase SIZ1 is essential for protein function in Arabidopsis. Deletion or mutation of the domain failed to complement a siz1 mutant, confirming its role in sumoylation. They also showed that the finger recognizes tri-methylated histone proteins, suggesting a role for the finger domain in SIZ1/SUMO-mediated transcriptional regulation of stress response-associated genes.

FDA: 7 Sunscreen Chemicals Enter Bloodstream After Use, But Don ’ t Abandon Sun Protection
(CNN) — After a single application, a total of seven chemicals commonly found in sunscreens can be absorbed into the bloodstream at levels that exceed safety thresholds, according to studies by the Center for Drug Evaluation and Research, an arm of the US Food and Drug Administration.
“What is most alarming about these findings is that chemicals are absorbing into the body in significant amounts and the ingredients have not been fully tested for safety,” said David Andrews, a senior scientist for the Environmental Working Group, or EWG, a consumer organization which advocates for sunscreen safety.
