‘The big chunky belemnite’: a new relict megateuthidid from the Oxfordian (Late Jurassic) of Wyoming, USA, and its place in the evolutionary history of the group

open access: yesPapers in Palaeontology, Volume 12, Issue 5, September/October 2026.
Abstract We describe and discuss two finds of large and untypical belemnite rostra originating from the upper part of the Sundance Formation (Oxfordian) of Wyoming, USA. With a diameter reaching c. 60 mm at the anterior end, these rostra are the thickest known for belemnites so far.

Impact of geometric factors and shear stress on endothelial function: Hemodynamic insights from human cerebral arterial bifurcations

open access: yesPhysiological Reports, Volume 14, Issue 11, June 2026.
Abstract Vascular inflammation is not a random biological event but rather a process that is strictly regulated by physical forces. While biochemical mediators are well characterized, the local physical mechanisms that predispose specific cerebral vascular sites to inflammation, specifically the geometry of arterial bifurcations, remain ...

Extreme Value Analysis of Solar Green‐Line Corona During the Time Interval 1939–2025

open access: yesSpace Weather, Volume 24, Issue 5, May 2026.
Abstract Predicting the probability of extreme solar events is critical to understanding how to mitigate risks associated with space weather disasters, as their occurrence can pose a threat to life and infrastructure on Earth or in near‐Earth orbit. In the present study, extreme value theory is applied to the daily modified coronal index (MCI) for the ...

Latitudinal Dependence of the Solar Wind During Periods of High and Low Activity Through Interplanetary Scintillation

open access: yesSpace Weather, Volume 23, Issue 7, July 2025.
Abstract We present a study of the solar wind over different periods of the solar cycle, specifically focusing on the minimum between solar cycles 24 and 25, and the active, ascending phase of solar cycle 25. With the use of interplanetary scintillation (IPS) data taken by the Murchison Widefield Array (MWA) from mid‐2019 and early 2023, we have ...
