Dominant spoilage bacteria in crayfish alleviate ultrasonic stress through mechanosensitive channels but could not prevent the process of membrane destruction [PDF]
Ultrasonics SonochemistryAlthough there have been many studies on the efficacy of ultrasonic inactivation, the stress resistance mechanism of bacteria is still a challenge for complete ultrasonic inactivation. In this study, the dominant spoilage bacteria in crayfish, Shewanella

Parasite-induced shell damage in brachiopod Porambonites (Porambonites) laticaudata from the Late Ordovician (Sandbian) of Estonia [PDF]
Estonian Journal of Earth Sciences, 2023 A new type of shell damage has been described in Ordovician brachiopods in Porambonites (Porambonites) laticaudata. There is a pair of small pits with somewhat different outline in the shell surface at the anterior commissure of the brachiopod.

Ordovician climate changes in the northern subtropics: The δ18O record from the Tunguska Basin, Siberia [PDF]
Estonian Journal of Earth Sciences, 2023 Oxygen isotopes from bioapatite (conodonts) have been used for several decades to reconstruct the Palaeozoic climate history. During the Ordovician, conodont-based δ18Ophos studies have revealed a general cooling trend throughout the system.
