Novel Frontiers in High-Entropy Alloys

open access: yesMetals, 2023
There is little doubt that there is significant potential for high-entropy alloys (HEAs) in cryogenic and aerospace applications. However, given the immense design space for HEAs, there is much more to be explored. This review will focus on four areas of

Seasonal transcriptomic shifts reveal metabolic flexibility of chemosynthetic symbionts in an upwelling region

open access: yesmSystems
Upwelling in the Tropical Eastern Pacific profoundly affects marine coastal ecosystems by driving drastic seasonal changes in water temperature, oxygen levels, and nutrient availability.

Morphological and molecular characterization of the trematodes (Digenea: Acanthocolpidae and Cryptogonimidae) of the black-spotted croaker (Protonibea diacanthus) (Teleostei: Sciaenidae) in northern Australia

open access: yesParasitology
Contributing to the knowledge of digenetic trematodes in northern Australia, this study uses both morphological and molecular analysis to augment the taxonomic descriptions of existing digenean trematodes from the black-spotted croaker, Protonibea ...

Friends With Benefits: Exploring the Phycosphere of the Marine Diatom Skeletonema marinoi

open access: yesFrontiers in Microbiology, 2019
Marine diatoms are the dominant phytoplankton in the temperate oceans and coastal regions, contributing to global photosynthesis, biogeochemical cycling of key nutrients and minerals and aquatic food chains. Integral to the success of marine diatoms is a

Transcriptional Mechanisms of Thermal Acclimation in Prochlorococcus

open access: yesmBio, 2023
Low temperature limits the growth and the distribution of the key oceanic primary producer Prochlorococcus, which does not proliferate above a latitude of ca. 40°. Yet, the molecular basis of thermal acclimation in this cyanobacterium remains unexplored.

Pirates and the Environment: Bajo Tribe Study in Marine Conservation [PDF]

open access: yesE3S Web of Conferences, 2020
Pirate is considered as one of the oldest professions in the world. The existence of pirates in the archipelago was first recorded in the 5th century AD. In the period of 15th to the 16th century, pirate activities increased due to political and economic

Planktonic Aggregates as Hotspots for Heterotrophic Diazotrophy: The Plot Thickens

open access: yesFrontiers in Microbiology, 2022
Biological dinitrogen (N2) fixation is performed solely by specialized bacteria and archaea termed diazotrophs, introducing new reactive nitrogen into aquatic environments.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
