Chemical Ligation of Backbone N‐hydroxylated Peptides

Chemistry – A European Journal, EarlyView.
Peptide backbone N‐hydroxylation enables sequence‐agnostic fragment ligation via hydroxamate O‐acyl capture and O→N acyl transfer in water. Broad tolerance of sterically demanding nucleophilic residues is observed, and reductive N─O cleavage restores the native amide bond.

Post‐LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor

Cytoskeleton, EarlyView.
ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit

The effects of vessel speed and size on the lethality of strikes of large whales in U.S. waters

Frontiers in Marine Science
Vessel strikes are a substantial source of mortality for large whales worldwide and may pose conservation threats for small populations. Model-based estimates of mortality rates, which inform management strategies to reduce vessel strike mortality ...

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Burrunan babble: acoustic characterization of the whistles and burst-pulse sounds of a critically endangered dolphin

Royal Society Open Science
Understanding the vocal repertoire of delphinid species is essential for effective long-term studies. In this research, we present the first quantitative analysis of whistle and burst-pulse sound characteristics for the critically endangered Burrunan ...

Biophysical processes of morphogenesis in lizard lungs

Developmental Dynamics, EarlyView.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.
