The statistics of Rayleigh-Levy flight extrema

Astronomy & Astrophysics
Rayleigh-Levy flights have played a significant role in cosmology as simplified models for understanding how matter distributes itself under gravitational influence. These models also exhibit numerous remarkable properties that enable predictions of a wide range of characteristics.

Mechanisms of haemoglobin mass expansion following heat stress

The Journal of Physiology, EarlyView.
Abstract figure legend Theorised mechanisms of heat stress‐induced erythropoiesis which may facilitate the expansion of haemoglobin mass. A, acute: heat stress‐induced renal ischaemia. Redistribution of blood flow away from the kidneys to facilitate thermoregulation during heat stress could reduce renal oxygen delivery, subsequently lowering renal PO2${

Characterizing Point‐Source Carbon Emissions by Combining TROPOMI CO and OCO CO2 Data

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Understanding and independently validating carbon emissions from concentrated point sources is vital to support climate policy. Satellite‐based quantifications of CO2 ${\text{CO}}_{2}$ point source emissions have been limited by the spatial coverage of current satellite instruments. We combine three different satellite instruments to determine

Integration of epigenetics into ecotoxicology: insights and fundamental research needs

Biological Reviews, Volume 101, Issue 2, Page 826-847, April 2026.
ABSTRACT Epigenetics refers to heritable changes in genome function that occur without direct alterations to the DNA sequence. A multitude of environmental contaminants can influence the epigenetic marks of a genome. Changes of epigenetic marks including DNA methylation, histone modifications, and non‐coding RNAs can induce alterations at the gene ...
