SC‐550: A Sintered Calcite Reference Material for In Situ U‐Pb Geochronology

Geostandards and Geoanalytical Research, EarlyView.
Key Points New calcite reference material (SC‐550) produced by high‐temperature and high‐pressure sintering of nano‐particulate powder from a microbial limestone. Homogeneous U content (2.3 ± 0.4 μg g‐1) and U‐Pb isotope ratios (< 0.6% RSD for 207Pb/206Pb; < 3% RSD for 238U/206Pb).

Facilitating Feeling?: The Relationship between Memorials and Emotions

Sociological Inquiry, EarlyView.
This article explores if and how national memorials impact collective emotions among local residents, focusing on the National Memorial for Peace and Justice (NMPJ) in Montgomery, Alabama. This understudied question is of sociological importance given the change in federal policy regarding public memorials, particularly the removal of references to ...

Impaired Windkessel function and proximal aortic stiffness: Linking vascular ageing to cognitive decline

Experimental Physiology, EarlyView.
Abstract Central arterial stiffening, particularly of the proximal aorta, is increasingly recognised as a pivotal contributor to cardiovascular disease, dementia, and mild cognitive impairment. Loss of Windkessel function amplifies pulsatile pressure, reduces diastolic perfusion and accelerates microvascular damage in the brain.

Quantitative MRI changes in neck muscle size and composition following long‐duration spaceflight

Experimental Physiology, EarlyView.
Abstract Long‐duration spaceflight poses several challenges to human health, including muscle loss and fat deposition. To mitigate these effects, exercise countermeasures are prescribed. This study aimed to measure neck muscle size and composition changes with long‐duration spaceflight using quantitative magnetic resonance imaging (MRI) and examine ...
