Plasticity of Gene Expression in Spaceflight and Postflight in Relation to Cardiovascular Disease: Mechanisms and Candidate Repurposed Drugs

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Spaceflight poses unique challenges to human health due to exposure to increased levels of cosmic radiation, microgravity, and associated oxidative stress. These environmental factors can lead to cellular damage, inflammation, and a range of health complications, including cardiovascular problems, immune system impairment, and an increased ...

Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten

open access: yesphysica status solidi (b), EarlyView.
This atomic‐scale study reveals how low‐to‐mid‐energy space irradiation alters tungsten's thermal and electronic behavior, even at low defect levels. Focusing on vacancy sites in bulk and near grain boundaries, it employs two novel approaches: site‐projected thermal conductivity and the N2$^{2}$ method for the thermal and electronic response analysis ...

Cosmic Ray Muon Physics

open access: yes, 2000
We present a review of atmospheric and underground muon flux measurements. The relevance of these data for the atmospheric neutrino flux computation is emphasized. Possible sources of systematic errors in the measurements are discussed, focusing on the sea level muon data. Underground muon data are also reported.

Hyperspectral Raman imaging to understand patterns in dried biofluids in Alzheimer's disease

open access: yesVIEW, EarlyView.
Raman spectroscopy is commonly used to identify biomarkers in biological fluids, often focusing on the outer ring of dried droplets due to molecular accumulation from the coffee ring effect. However, this approach may overlook important spectral information, so hyperspectral Raman mapping is used to analyze the entire droplet and identify optimal ...

A cross‐correlator‐based timing tool for FemtoMAX

open access: yesJournal of Synchrotron Radiation, EarlyView.
A novel timing tool suited for FemtoMAX is described. This will allow sub‐100 fs time‐resolved measurements at FemtoMAX.We report on the commissioning of an ultrafast timing diagnostic for measuring a time‐offset signal between two different synchronized ultrashort light pulses.

Vision at high latitudes: High sensitivity without specific boreal adaptations in photoreception in reindeer (Rangifer tarandus L.)

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

Affective assemblages of kinship and single mothers’ labour migration from a ‘climate hotspot’

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
In coastal Bangladesh, ‘affective assemblages of kinship’ produce differential abilities for landless single mothers to migrate to brick kilns, the garment industry, and the Gulf. This group of women who return to their natal homes as a response to violence or abandonment is neglected by anthropologists of kinship and migration. Thinking of assemblages
