The Chemistry and Biology of the Tetrodotoxin Natural Product Family

open access: yesAngewandte Chemie International Edition, EarlyView.
Tetrodotoxin is best known as the poison of the pufferfish, which is a delicacy in Japanese cuisine. Its toxicity arises from the selective blockage of NaV channels, which is depicted for the NaV1.7 pore, highlighting the DEKA motif, which permeates sodium ions.

Design of Fluorine‐Free Weakly Coordinating Electrolyte Solvents with Enhanced Oxidative Stability

open access: yesAngewandte Chemie International Edition, EarlyView.
Incorporation of silicon is systematically explored as a sustainable strategy to design weakly solvating electrolytes for lithium‐based batteries. After identifying a promising molecular structure via computational screening, coordination spheres and their correlation with electrochemical key performance indicators are compared between electrolyte ...

Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?

open access: yesThe Anatomical Record, EarlyView.
Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...

Exposed weapons: A revised reconstruction of the facial anatomy and life appearance of the saber‐toothed cat Megantereon (Felidae, Machairodontinae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Megantereon was a widespread saber‐toothed felid from the Pliocene and Pleistocene of the Old World and North America, but its rarity in the fossil record makes it complicated to restore its life appearance. Lack of complete specimens makes it necessary to combine information from fossils of different individuals to reconstruct their facial ...

Shaping the human face: Periosteal bone modeling across ontogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Facial morphology is a defining aspect of Homo sapiens that distinguishes our species from fossil ancestors and plays a central role in estimating age, sex, and ancestry in both past and present populations. Understanding how the face develops during postnatal ontogeny is essential for interpreting adult facial variation.

Meta2: A meta‐analysis and psychometric evaluation of the Metacognitive Awareness Inventory (MAI) in the context of health professions education

open access: yesAnatomical Sciences Education, EarlyView.
Abstract To keep pace with medicine's unpredictable changes, medical trainees must learn to accurately monitor and evaluate themselves via metacognition (i.e., thinking about thinking). The Metacognitive Awareness Inventory (MAI) can assess and guide the metacognitive development of trainees.
