Revisiting classical biological control of Hydrilla verticillata: historical perspective and new opportunities

Biological Control
The invasive aquatic plant Hydrilla verticillata continues to threaten freshwater systems in the USA. Management is complicated by presence of three genetically distinct subspecies, of which H. verticillata ssp. lithuanica is the most recent introduction

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

A NEW SPECIES OF EUDAMUS [PDF]

The Canadian Entomologist, 1892
Eudamus coyate: Expands 2⅛i inches. Primaries dark glossy brown, several shades darker than Eudam. bathyllus; fringes of same colour as the wings. The apices of the wings run more to a point than in other species of the genus. There are no markings on the primaries, although there are some very faint indications of markings, which are not brought out ...

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

FEBS 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 ...

Cross‐Validation of Diet Determination Methods for Seabird Conservation

Environmental DNA
Seabirds are recognized as one of the most vulnerable groups of birds, with around a third of species identified as globally threatened. The conservation of seabirds is often linked with their feeding and diet, due to undesirable interactions with human ...

A NEW SPECIES OF NEONYMPHA [PDF]

The Canadian Entomologist, 1889
Neonympha Mitchellii n. sp.Male.—Upper surface grayish wood-brown, rather dark, without spots or marks, except that the spots on the underside of the hind wings and the dark lines bordering the terminal dark yellow line on the same wings show through a little. Fringes concolorus, in certain lights a little smoky tinged.

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS 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
