The barley–malt–beer chain: A process and food safety approach

open access: yesJSFA reports, Volume 6, Issue 5, Page 144-159, May 2026.
Abstract This review addresses the current state of knowledge on the barley–malt–beer chain and its main physical, chemical, and microbiological contaminants, with particular emphasis on spoilage microorganisms and their toxic metabolites. The barley–malt–beer production chain represents a mature and globally relevant agro‐industrial sector that ...

Martian crater counts on Elysium Mons [PDF]

open access: yes
Without returned samples from the Martian surface, relative age chronologies and stratigraphic relationships provide the best information for determining the ages of geomorphic features and surface regions.

Deep Learning Reconstruction Enables Diagnostic‐Quality 0.4T Knee and Spine MRI in One‐Third of the Time

open access: yesNMR in Biomedicine, Volume 39, Issue 5, May 2026.
The deep learning model CIRIM successfully accelerated knee and spine data up to an acceleration factor of 3, after optimizing the undersampling mask and loss function. The model demonstrated robustness and generalizability to different contrasts, matrix sizes, orientations, and anatomies. ABSTRACT There has been a growing interest in low‐field MRI due

In‐and‐Out: Algorithmic Diffusion for Sampling Convex Bodies

open access: yesRandom Structures &Algorithms, Volume 68, Issue 3, May 2026.
ABSTRACT We present a new random walk for uniformly sampling high‐dimensional convex bodies. It achieves state‐of‐the‐art runtime complexity with stronger guarantees on the output than previously known, namely in Rényi divergence (which implies TV, 𝒲2, KL, χ2$$ {\chi}^2 $$).

Tracking Microhydration of the NaCl Rocksalt Molecule by Quantum Chemical Calculations and Penning Ionization Electron Spectroscopy in Helium Nanodroplets

open access: yesSmall Structures, Volume 7, Issue 5, May 2026.
This study combines quantum chemical calculations and high‐resolution Penning ionization electron spectroscopy in helium nanodroplets to investigate NaCl microhydration. It reveals the transition from contact to solvent‐separated ion pairs and quantifies hydration shell completion at about 34 water molecules.

Greenhouse Gas Dynamics From Created Wetlands of New Brunswick and Nova Scotia (Canada)

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Beginning in the 17th century, Acadian settlers dyked and drained salt marshes along the Bay of Fundy in Eastern Canada, transforming them into agricultural fields. Over the last ∼50 years, impoundments were created by building dykes to contain freshwater.
