Sharpening our understanding of saber‐tooth biomechanics
The Anatomical Record, EarlyView.Abstract Saber‐teeth are a striking example of convergent evolution in vertebrate predators, having evolved multiple times in mammals and their early ancestors. While there is broad consensus that saber‐toothed taxa employed a distinct biting strategy compared to conical‐toothed carnivores, like the lion, the precise mechanics and variability of this ...

A remarkable recurrent nova in M 31: The 2010 eruption recovered and evidence of a six-month period
, 2015 The Andromeda Galaxy recurrent nova M31N 2008-12a has been caught in eruption nine times. Six observed eruptions in the seven years from 2008 to 2014 suggested a duty cycle of ~1 year, which makes this the most rapidly recurring system known and the ...

The Anatomical Record, EarlyView.Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

Commentary: What's so interesting about sabertooths?
The Anatomical Record, EarlyView.Abstract Sabertooth creatures are fascinating to the public and to scientists. This Special Issue on The Anatomy of Sabertooths starts with a discussion of what exactly a sabertooth is, continues with a couple of papers about other animals with extraordinarily long teeth, and then delves into analyses of fossil sabertoothed taxa—some of which are not ...

Two Step Filament Eruption During 14-15 March 2015
, 2017 We present here an interesting two-step filament eruption during 14-15 March 2015. The filament was located in NOAA AR 12297 and associated with a halo Coronal Mass Ejection (CME).

The Anatomical Record, EarlyView.Abstract Geometric morphometric analyses are used to explore variation of maxillary dental arcades of Australopithecus afarensis, expanding on the work of Hanegraef and Spoor, 2025 (Morphological variation of the Australopithecus afarensis maxilla.

The Eruption of Vesuvius [PDF]
Nature, 1906 YESTERDAY I ascended the cone of Vesuvius up to the crater, being, I suppose, one of the first climbers after the eruption. The ascent was made from Torre Annunziata witnout any difficulties, but care had to be taken to avoid the courses of the avalanches of stones and ashes rushing from the cone and spreading over the slopes more than half a mile from

Polymorphous light eruption [PDF]
Journal of the American Academy of Dermatology, 1980 The polymorphous light eruptions are idiopathic photodermatoses characterized by various clinical patterns ranging from small papules and papulovesicular lesions to large papules that coalesce to form plaques. The eruptions may begin at any time of life from young childhood to old age, and any race may be afflicted.

The Anatomical Record, EarlyView.Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Journal of Investigative Dermatology, 1987 Polymorphous light eruption (PLE) is a common photodermatosis of unknown etiology. It afflicts mainly fair-skinned patients, with a preponderance of young females. There is, however, no absolute restriction as to age, sex, or race. Clinical variants include the papular, vesiculo-bullous, and hemorrhagic variety, as well as plaque, erythema multiforme ...
