Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Understanding the spacing of placodes in the eye: A comparative study across age and species

open access: yesThe Anatomical Record, EarlyView.
Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.

Clade‐wide morphological and functional variation of the sauropsid columella

open access: yesThe Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

An extremely fast fading population II dwarf nova candidate: caught spectroscopically on the rise

open access: yesMonthly Notices of the Royal Astronomical Society
ABSTRACT In the first observational run of the Kilonova and Transients Programme (KNTraP), a rapidly evolving optical transient, KNTraP2022-02a (TNS name: AT2022kak), was discovered. This interesting burst exhibited extremely fast evolution, with a large amplitude blue outburst of $m \gt $ 3.3 in a single night, and a rapid fade back ...

Milk: Nature's Unique Nutritional Package

open access: yesAnimal Research and One Health, EarlyView.
ABSTRACT Plant‐based beverages that attempt to mimic milk are increasingly popular with consumers, but there are profound differences in nutritional composition and microstructure compared to milk. A structural nutrition approach is needed to understand the effect on digestibility of microstructures, bioaccessibility and bioavailability of components ...

Interval Timing Is Altered in Male Nrxn1+/− Mice: A Model of Autism Spectrum Disorder

open access: yesAutism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is characterized by impaired social interactions and communication, and increased repetitive and stereotypical behavior. Neuroimaging shows functional abnormalities in brain areas involved in temporal processing in autistic individuals, and they also show deficits in interval timing.

V1663 Aquilae: A Fast Fe ii-type Nova that Formed Dust and Coronal Lines

open access: yesResearch Notes of the AAS
Abstract V1663 Aquilae was a rare nova that formed both dust and coronal emission lines. A spectrum from 157 days after peak brightness shows both thermal dust emission and coronal emission present at the same epoch. An earlier spectrum from 36 days post maximum captures the nova prior to the formation of either dust or high-excitation ...

Exploring the potential of ucuúba (Virola surinamensis) seed fat

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Ucuúba (Virola surinamensis) fat is an important income source for Amazonian communities. Local businesses typically process whole seeds for fat extraction; however, seed structural integrity may influence extraction efficiency and fat quality.

One‐Pot Synthesis of a Small Synthetic Ligand for Antibody Purification

open access: yesBiotechnology and Bioengineering, EarlyView.
One‐pot liquid‐phase synthesis of the synthetic ligand B1Al2A2 enables controllable ligand density and efficient capture of IgG and IgY with high recovery and purity, streamlining small‐ligand affinity purification workflows. ABSTRACT The development of synthetic affinity ligands offers a cost‐effective alternative to traditional biological ligands ...
