New Natural and Fused Quartz Reference Materials for Oxygen Isotope Microanalysis [PDF]

, 2020
Silicon dioxide (SiO2) occurs as both crystallized quartz and amorphous quartz, and their oxygen isotope is widely used to trace the source of hydrothermal fluids, to reconstruct paleotemperature of oceans and to provide genetic constraints on ...

Use of Flame Atomic Absorption Spectrometry in Diagnosis of Cancerous and Non-Cancerous Breast Tissues: Comparison of Metal Concentrations [PDF]

, 2010
Metals play important roles for cellular functions and also for generating oxidative DNA damages. Furthermore, they are considered to act not only as carcinogens but also as co-carcinogens which activate carcinogenic chemicals.

Gravitational atom spectroscopy

Physical Review D
Black holes in our Universe are rarely truly isolated, being instead embedded in astrophysical environments such as plasma or dark matter. A particularly intriguing possibility is that light scalar fields form bound states around black holes, producing extended “clouds” known as .

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
