Overview of Trends in Plankton Communities [PDF]

, 2011
Phytoplankton and zooplankton occupy pivotal positions within marine ecosystems. These small organisms fuel and support the foodwebs upon which almost all higher organisms depend.

Technical Service - Swedish request on the production of yearly (2009–2018) swept-area ratio (SAR) values in the Swedish EEZ

, 2020
ICES has produced, as a technical service to Sweden, a time-series (2009–2018) of fishing intensity in the Swedish EEZ according to the customized gear grouping of surface and subsurface swept-area ratio (SAR) aggregate values.

Surface Charging of Jupiter’s Moon Europa

The Astrophysical Journal Letters
Europa’s surface is exposed to a constant flow of plasma from its ionosphere and Jupiter’s magnetosphere. As these particles flow onto the surface, an electrostatic surface potential forms.

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

FEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

MiR‐513a promotes human erythroid differentiation by modulating c‐Jun

FEBS Open Bio, EarlyView.
During early human erythropoiesis, miR‐513a promoted erythroid differentiation in primary human CD34+ hematopoietic stem‐progenitor cells and human TF‐1 erythroleukemic cells by indirectly decreasing c‐Jun and phospho‐c‐Jun expression, which are associated with increased GATA1 expression.

Global Distribution of the Key Species on the Surface of Europa

The Astrophysical Journal
The icy surface of Europa is continuously bombarded by ions and electrons from Jupiter’s magnetosphere. The bombardment of the particles dissociates water molecules on the surface of Europa and introduces impurities to the icy surface.

Rapid screening of staphylokinase protein variants using an unpurified cell‐free expression system

FEBS Open Bio, EarlyView.
An unpurified cell‐free protein synthesis (CFPS) platform enables rapid functional screening of staphylokinase variants. Direct plasminogen‐activation assays performed in microplate format provide real‐time activity readouts, allowing rapid identification and ranking of variants with improved or reduced fibrinolytic activity without protein ...

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Formation of All Three C2H4O Isomers—Ethylene Oxide (c-C2H4O), Acetaldehyde (CH3CHO), and Vinyl Alcohol (CH2CHOH)—in Ethanol-containing Interstellar Analog Ices

The Astrophysical Journal
Oxygen-containing complex organic molecules are key precursors to biorelevant compounds fundamental for the origins of life. However, the untangling of their interstellar formation mechanisms has just scratched the surface, especially for oxygen ...
