Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Discovery of an Atypical Arp2/3 Complex in Malaria Parasites Sheds New Light on Nuclear Actin

Cytoskeleton, EarlyView.
ABSTRACT The Arp2/3 complex is a key actin nucleator essential for cytoskeletal dynamics in eukaryotes. Previously believed absent in apicomplexan parasites, we recently identified an atypical Arp2/3 complex in malaria parasites consisting of five divergent subunits and a putative kinetochore‐associated factor.

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age

Journal of Quaternary Science, EarlyView.
ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.

Amebaborne “Attilina massiliensis” Keratitis, France

Emerging Infectious Diseases, 2018
We report a case of Acanthamoeba castellani keratitis in a person who wore contact lenses. The amebae hosted an ameba-resistant bacterial symbiont, provisionally named “Attilina massiliensis,” a yet undescribed α-Proteobacterium.

Tumor Cell Migration May Be an Inherent “Foraging” Behavior

Medicine Advances, EarlyView.
Tumor cells gradually form pseudopodia, migrate to necrotic cells, make contact with them, and absorb necrotic cell debris. During this migration, small vesicles formed by dying tumor cells also gradually migrate toward living tumor cells. Once the nutrients from the necrotic cells have been completely absorbed, the living tumor cells will leave ...

Marseilleviruses: An Update in 2021

Frontiers in Microbiology, 2021
The family Marseilleviridae was the second family of giant viruses that was described in 2013, after the family Mimiviridae. Marseillevirus marseillevirus, isolated in 2007 by coculture on Acanthamoeba polyphaga, is the prototype member of this family ...

Sustainability as Justice: Making the “Leave No One Behind” Work

Sustainable Development, EarlyView.
ABSTRACT This paper critically engages with the LNOB principle of the 2030 Agenda, highlighting its conceptual, methodological, and structural limitations. Building on Amartya Sen's social choice theory and Rawlsian justice, it reconceptualizes “sustainability as justice,” emphasizing real‐world comparative assessments grounded in intersectionality. It

Cooperation and conflict in the social amoeba Dictyostelium discoideum.

International Journal of Developmental Biology, 2019
The social amoeba Dictyostelium discoideum has provided considerable insight into the evolution of cooperation and conflict. Under starvation, D. discoideum amoebas cooperate to form a fruiting body comprised of hardy spores atop a stalk.
