Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

In Vivo Imaging of the Innate Immune System in the Pancreas in New‐Onset and Long‐Standing Type 1 Diabetes

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Objective Type 1 diabetes (T1D) is an autoimmune disease, but knowledge of immune cell infiltration in the human pancreas is limited due to the risks associated with pancreatic biopsies. This study aimed to evaluate the feasibility of imaging innate immune cells in vivo using positron emission tomography (PET).

Examining the Role of Artificial Intelligence in Assessment: A Comparative Study of ChatGPT and Educator‐Generated Multiple‐Choice Questions in a Dental Exam

European Journal of Dental Education, EarlyView.
ABSTRACT Aim To compare the item difficulty and discriminative index of multiple‐choice questions (MCQs) generated by ChatGPT with those created by dental educators, based on the performance of dental students in a real exam setting. Materials and Methods A total of 40 MCQs—20 generated by ChatGPT 4.0 and 20 by dental educators—were developed based on ...

Noble gases and nitrogen in material from asteroid Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.
