‘Guide and Prejudice’— How Argonautes recognize targets across domains of life

open access: yesFEBS Letters, EarlyView.
Argonaute proteins use short nucleic‐acid guides to locate and regulate specific targets across all domains of life. Despite striking diversity—from human gene silencing to bacterial immune defence—all Argonautes share a conserved three‐stage recognition logic: guide‐directed sampling, progressive target pairing with a conformational checkpoint and ...

Reproductive patterns of deep-sea invertebrates related to phylogeny and energy availability

open access: yes, 2000
Reproductive strategies and their interaction with the environment play a major role in the shaping of ecosystems. However, while our understanding of the diversity, biogeography and ecology of deep-sea invertebrates has increased considerably in the ...

Design and Control Strategy for a Solar -Powered Autonomous Underwater Vehicle with an Unconventional Shape

open access: yesPolish Maritime Research
Solar-powered autonomous underwater vehicles (SAUVs) can harness sustainable natural energy, meaning that they are capable of providing long-term mission support. This paper describes ongoing development work on the overall design of a SAUV.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

open access: yesFEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Phylogenetics, systematics and biogeography of deep-sea Pennatulacea (Anthozoa: Octocorallia): evidence from molecules and morphology

open access: yes, 2008
Despite its extreme environmental conditions, the deep sea harbours a unique andspecies-rich fauna of mostly unknown age and phylogeny. Pennatulids (Anthozoa:Octocorallia) are a group whose taxonomy and phylogenetic relationships remain poorlyknown and ...

Abiotic Siliceous Botryoids on Iron Oxyhydroxide Filaments From Hydrothermal Vents in the Southwest Indian Ocean

open access: yesGeochemistry, Geophysics, Geosystems
Fe‐oxidizing microorganisms in deep‐sea hydrothermal vent environments are often used as analogs for primordial life on Earth. In fact, Earth's oldest purported microfossils are preserved as hematite filaments in a jasper rock dated between 4,160 and 4 ...

Prospecting the protein design landscape

open access: yesFEBS Letters, EarlyView.
This review outlines the current state of various protein design approaches. We discuss the current possibilities enabled by recently released tools, highlight future avenues to pursue in protein design, and underscore the crucial role of key databases and resources for successful protein design workflows.

Community structure and spatial distribution of vent fauna in the hydrothermal fields of North Fiji Basin based on ROV visual survey

open access: yes, 2018
This study was conducted to investigate the community structure and distributional pattern of hydrothermal and adjacent deep-sea fauna at two hydrothermal vent fields (KF2 and KF3) on the central spreading axis in North Fiji Basin, from November to ...
