TolC Is Required for a Mixed‐Linkage β‐Glucan (MLG) Biosynthesis: Engineering Bacteria for MLG Overproduction

Microbial Biotechnology, Volume 19, Issue 8, August 2026.
TolC is identified as an essential component of the mixed‐linkage β‐glucan (MLG) biosynthetic machinery in Sinorhizobium meliloti, likely enabling polymer export. Co‐expression of tolC, bgsBA, and pleD* significantly enhances MLG production and enables its synthesis in non‐native bacterial hosts.

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Conservation implications of low contemporary connectivity along the Mid‐Atlantic Ridge in hydrothermal vent gastropods

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Polymetallic sulfide deposits produced at hydrothermal vent fields are targets for mining exploitation along the Mid‐Atlantic Ridge, threatening the functioning and resilience of vent ecosystems that provide multiple ecosystem services. Knowledge about connectivity between vents will inform conservation practices.

Forecasting Climate Change Using a Multivariate Cointegrated System

Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 783-802, August 2026.
ABSTRACT A cointegrated vector equilibrium correction model of key climate variables including sea surface temperature, ocean heat content, Arctic sea‐ice extent and sea‐level change is built, driven by radiative forcing in which a stochastic trend arises due to anthropogenic emissions of greenhouse gases.

Sedimentology of silica granules and haematite in the 3.47 Ga Antarctic Creek Member, Mount Ada Basalt, Western Australia

Sedimentology, Volume 73, Issue 5, Page 1842-1866, August 2026.
ABSTRACT The Paleoarchean Antarctic Creek Member of the Mount Ada Basalt, Eastern Pilbara Terrane, Western Australia, includes beds of jasper and white chert composed of sand‐sized silica granules that often contain or are mixed with silt‐sized particles of haematite.

Isentropic Mixing and Formation of the Antarctic Bottom Water

Isentropic Mixing and Formation of the Antarctic Bottom Water
P(論文) A possible effect of the isentropic mixing on the formation of the Antarctic Bottom Water is explored by using a numerical model of oceanic general circulation. The isentropic mixing increases the rate of deep and bottom water mass formation. The meridional circulation is waxed. The meridional heat transport is correspondingly increased.

Internal Tide Displacements Enhance Surface‐Interior Heat Exchange in the Indonesian Seas

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Sea surface temperature (SST) in the Indonesian Seas drives atmospheric deep convection, influencing regional and global climate. Yet, the processes controlling SST in this region remain poorly understood. Using a high‐resolution regional model that explicitly resolves internal tides, we show that tidal displacements lift cold thermocline ...

Distinct El Niño Flavors and SAM Variability Modulate Surface Melt Over the Ross Ice Shelf

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Our study investigates how different flavors of El Niño, centered on the Eastern Pacific (EP) and Central Pacific (CP), and their interaction with the Southern Annular Mode (SAM) modulate surface melt events over the Ross Ice Shelf (RIS). Using satellite‐based melt observations, ERA5 reanalysis, high‐resolution regional model simulations, and ...
