Welfare assessment of turkeys (Meleagris gallopavo gallopavo) on farm

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract This Scientific Opinion assesses the welfare of turkeys of all ages (Meleagris gallopavo gallopavo) on farm in relation to the type and condition of the litter, type and availability of enrichment (including covered veranda and outdoor range), space allowance, concentrations of ammonia and carbon dioxide, effective environmental temperature ...

Challenges of understanding the variability of the Van Allen radiation belts

, 2023
Understanding the variability of the Van Allen radiation belts, populations of energetic particles trapped on fairly stable orbits within the Earth’s magnetosphere, has been one of the outstanding questions in heliophysics research. NASA’s Van Allen Probes Mission (2012-2019), two identical probes in low inclination geo-transfer orbit (GTO), has been ...

Future Shoaling of the AMOC and Its Impact on Oceanic Heat Transport to the Subpolar North Atlantic

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Atlantic Meridional Overturning Circulation (AMOC) carries oceanic heat northward to the subpolar North Atlantic (SPNA), where the surface water cools and sinks to the deep ocean. According to a large‐ensemble simulation under a medium‐to‐high emission scenario, the surface cooling and oceanic heat convergence in the SPNA may decrease to ...

VLF waves from ground‐based transmitters observed by the Van Allen Probes: Statistical model and effects on plasmaspheric electrons

Geophysical Research Letters, 2017
Whistler mode very low frequency (VLF) waves from powerful ground‐based transmitters can resonantly scatter energetic plasmaspheric electrons and precipitate them into the atmosphere.

Investigation of EMIC wave scattering as the cause for the BARREL 17 January 2013 relativistic electron precipitation event: A quantitative comparison of simulation with observations [PDF]

, 2014
Electromagnetic ion cyclotron (EMIC) waves were observed at multiple observatory locations for several hours on 17 January 2013. During the wave activity period, a duskside relativistic electron precipitation (REP) event was observed by one of the ...
