Thermospheric Density Disturbances During the 2015 St. Patrick's Day Geomagnetic Storm: Model–Observation Comparisons and Analysis of Intense Polar Density Spikes

Space Weather, Volume 23, Issue 10, October 2025.
Abstract Drag affecting satellites in low Earth orbit varies significantly during geomagnetic storms due to changes in thermospheric density. While neutral density can be inferred from satellite measurements, such data sets are limited and restrict neutral density/orbit prediction capabilities.

Tropical Tropopause Layer Evolution During QBO Disruptions

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 18, 28 September 2025.
Abstract The tropical tropopause layer (TTL) is studied during 2015/16 and 2019/20 quasi‐biennial oscillation (QBO) disruption events using GNSS‐RO and SWOOSH satellite observations and the ERA5 reanalysis. By compositing temperature, water vapor, and tropical upwelling during different phases of QBO and QBO disruptions (XQBO), we show that XQBO events

Absence of Blood Chimerism in Twin Goeldi's Monkeys (Callimico goeldii): Implications for Interpreting Callitrichid Phylogeny

American Journal of Primatology, Volume 87, Issue 9, September 2025.
All Callitrichidae have twins who are chimeras, but Callimico has singletons. We examined evidence of blood chimerism in the only known surviving Callimico twins, and found that they were non‐chimeric. This represents the first report of the absence of blood chimerism in twins of any callitrichid species.

Preliminary notes on the population structure of Heterobasidion abietinum from Abies pinsapo in Spain

Phytopathologia Mediterranea, 2009
A molecular study using M13 minisatellite amplifi cation was carried out to ascertain the origin of the fungal isolates of Heterobasidion abietinum collected from Abies pinsapo in Andalucia (Spain). Isolates were compared with those from A.

Thermospheric Density, Composition, and Temperature From GOES‐R/SUVI Solar Occultations

Space Weather, Volume 23, Issue 9, September 2025.
Abstract A new data set of atomic oxygen (O) and molecular nitrogen (N2 ${\mathrm{N}}_{2}$) number density profiles, along with thermospheric temperature profiles between 180 and 500 km, has been developed. These profiles are derived from solar occultation measurements made by the Solar Ultraviolet Imager (SUVI) on the GOES‐R satellites, using the 17.1,

A Gravity Study of the Crustal Structure Beneath the Young Amagmatic Rukwa‐Tanganyika Rift Zone

Tectonics, Volume 44, Issue 8, August 2025.
Abstract The Rukwa‐Tanganyika Rift Zone (RTRZ), experiencing multiphase rifting, forms the nonvolcanic southern part of the Western Branch of the East African Rift. We investigate the crustal structure beneath the RTRZ to understand how strain migrates beneath multiphase rifts.

Seasonal Variability of the DE3 and DE2 Non‐Migrating Tides in Middle Thermospheric Temperature and Composition During October 2018–August 2021 as Revealed by GOLD

Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.
Abstract A subset of non‐migrating tides, including the diurnal eastward propagating tides with zonal wavenumbers 3 and 2, respectively, referred to as DE3 and DE2, are upward propagating waves that have been studied as phenomena that couple the lower atmosphere with the thermosphere. While the climatology of non‐migrating tides in the mesosphere/lower
