River channel response to invasive plant treatment across the American Southwest

Earth Surface Processes and Landforms, Volume 48, Issue 3, Page 569-581, 15 March 2023., 2023
We analyzed channel change following invasive riparian vegetation treatment along 13 rivers, comparing treated to untreated reaches, and changes with unit stream power. Treatment led to significant channel widening and floodplain destruction, but not floodplain formation and channel migration.

Metformin has heterogeneous effects on model organism lifespans and is beneficial when started at an early age in Caenorhabditis elegans: A systematic review and meta‐analysis

Aging Cell, Volume 21, Issue 12, December 2022., 2022
Across studies, metformin seems to prolong lifespan in nematodes fed a specific bacterial diet but not in mice and may have a larger effect if started early in life. Abstract There is growing interest in the use of metformin to extend lifespan and prevent the onset of age‐related disorders in non‐diabetic individuals.

Immature skulls of the theropod dinosaur Coelophysis bauri from Ghost Ranch, New Mexico [PDF]

Acta Palaeontologica Polonica
The theropod dinosaur Coelophysis bauri is well known from the famous Rhaetian, Late Triassic mass death assemblage from the Coelophysis Quarry at Ghost Ranch, New Mexico. This research describes the skulls of two small individuals of C. bauri.

Revisiting the Happy Jack Uraninite Reference Material: A Combined Electron Beam and Laser Ablation In Situ Study

Geostandards and Geoanalytical Research, Volume 46, Issue 4, Page 735-749, December 2022., 2022
Key Points A comprehensive in situ mineral‐chemical characterisation of a Happy Jack (HJ) uraninite RM fragment is presented. Homogeneity/heterogeneity in the Happy Jack uraninite was observed on different scales. There was an absence of discernible matrix effects of HJ uraninite relative to the silicate glass NIST SRM 610.

Modeling Dragons: Using linked mechanistic physiological and microclimate models to explore environmental, physiological, and morphological constraints on the early evolution of dinosaurs.

PLoS ONE, 2020
We employed the widely-tested biophysiological modeling software, Niche Mapper™ to investigate the metabolic function of the Late Triassic dinosaurs Plateosaurus and Coelophysis during global greenhouse conditions.

A small venomous reptile from the Late Triassic (Norian) of the southwestern United States [PDF]

PeerJ
Reptile feeding strategies encompass a wide variety of diets and accompanying diversity in methods for subduing prey. One such strategy, the use of venom for prey capture, is found in living reptile clades like helodermatid (beaded) lizards and some ...

Lonergan, Decolonization and First Nations Peoples: An Apologetic from an Insider on the Outside

Modern Theology, EarlyView.
Abstract The purpose of this article is to respond critically to a research project initiated out of the Board of the Lonergan Research Institute that seeks to expose colonialist assumptions in Lonergan's thought. Some of the initiatives seek to link Lonergan with complicity in Canadian residential schools, spiritual violence, and cultural genocide ...

Are the dinosauromorph femora from the Upper Triassic of Hayden Quarry (New Mexico) three stages in a growth series of a single taxon?

Anais da Academia Brasileira de Ciências
The lagerpetid Dromomeron romeri and the theropod Tawa hallae are two dinosauromorphs from the Norian (Upper Triassic) of the Chinle Formation, situated in New Mexico, USA. However, a recent study suggests the inclusion of the holotype of D.

Shifting the Paradigm: Redefining the Chronostratigraphy of the Triassic Rewan Group, Bowen Basin, Australia

Basin Research, Volume 38, Issue 3, May–June 2026.
New U–Pb zircon dating shows the Rewan Group was deposited between ~250 and 233 million years ago and that sedimentation shifted across the basin through time, with earlier deposition in the foredeep and later deposition in the back bulge. Testing multiple dating approaches and grain‐selection strategies improves confidence in these age estimates and ...

A new taxon of saurischian dinosaur from the Coelophysis Quarry of New Mexico, USA (Triassic: latest Norian or Rhaetian) highlights herrerasaurian diversity in the latest Triassic

Papers in Palaeontology, Volume 12, Issue 2, March/April 2026.
Abstract The most complete record of the earliest dinosaur lineages is from the Carnian from the higher latitudes of Pangea (e.g. present‐day Brazil, Argentina), but dinosaurian assemblages from the upper stages of the Upper Triassic are better known from the low latitudes of Pangea (present day southwestern USA).
