Differential Activity of Coexisting Prochlorococcus Ecotypes

Frontiers in Marine Science, 2019
The abundance and widespread distribution of the unicellular cyanobacterium Prochlorococcus is attributed to its extensive genetic diversity. At least twelve distinct clades, or ecotypes, of Prochlorococcus have been discovered so far, and follow ...

Deuterium Isotope Probing: a potential game-changer in assessing chemical persistency in soil [PDF]

, 2023
Chemical persistency studies are crucial for the regulatory risk assessment of chemicals. One of their major challenges is the formation of so-called non-extractable residues (NERs) in soil as current analytics cannot easily differentiate hazardous ...

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

¹⁵N stable isotope probing of pulp and paper wastewaters [PDF]

, 2008
Stable isotope probing (SIP) is an established technique that can be applied to identify the metabolically active micro-organisms within a microbial population.

Organic Matter Micro-Interfaces Change Glyphosate Partitioning and Alter Active Glyphosate Degraders in Soils

Agriculture
Soil microorganisms are responsible for natural glyphosate dissipation. However, previous studies have largely focused on bulk soils, and the underlying microscale mechanisms remain poorly resolved.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

A culture-independent approach to unravel uncultured bacteria and functional genes in a complex microbial community [PDF]

, 2012
Most microorganisms in nature are uncultured with unknown functionality. Sequence-based metagenomics alone answers 'who/what are there?' but not 'what are they doing and who is doing it and how?'.

Cryogenic Deformation Behavior of TiAl and Insights Into Embrittlement After High‐Temperature Exposure Combined With Secondary Ion Mass Spectroscopy of Near Surface Chemistry

Advanced Engineering Materials, EarlyView.
Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

Stable-Isotope Probing RNA to Study Plant/Fungus Interactions

, 2016
International audienceThe use of stable-isotope probing (SIP) allows tracing specific labeled substrates into fungi leading to a better understanding of their role in biogeochemical cycles and their relationship with their environment.
