Single‐Breathhold 3D MR Elastography in the Liver, With Simultaneous R2* and PDFF Mapping

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 2, Page 682-697, August 2026.
Purpose To develop a sequence for the rapid acquisition of MR elastography (MRE) parameters in 3D, with simultaneous measurement of proton‐density fat fraction (PDFF) and R2* for multiparametric assessment of liver disease. Methods The proposed sequence uses an interleaved motion‐encoding scheme to acquire 3D volumes of all motion encodings and wave ...

The Revo‐Evo Debate in the History and Philosophy of Science

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
The paper juxtaposes revolutionary and evolutionary positions in epistemology in general as well as the history of science. While it deems the evolutionary arguments more persuasive, it also stresses the dependence of our assessment of change on the language we choose to describe the theories and positions under consideration.

A Dialogue on Revolutions and Revolutionaries in Science: A Perspective From Quantum Mechanics

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT We discuss the notions of scientific revolutions and revolutionaries in the context of the Relativity Revolution and of the First, Second, and Third Quantum Revolutions. We conclude that at the core of the question of what qualifies as a revolution and revolutionary is an assessment of the gradients of knowledge accumulation over time, both at

How important are quantum mechanical effects in controlling biological functions: Enzymes, electron transfer and bird navigation

open access: yesProtein Science, Volume 35, Issue 7, July 2026.
Abstract In light of the centennial of the Schrödinger equation, this article addresses the popular idea that quantum mechanical effects play an important role in biological systems. We start by defining what is qualified as a quantum effect. We then clarify the idea that quantum mechanical tunneling is a crucial factor in enzyme catalysis.
