Monitoring of Metabolic Disorders Through Electro‐Sensing of Riboflavin by Novel Super‐Conductive Silver Ink Modified Paper

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Riboflavin (RIB), or vitamin B2, plays a key role in cellular protection against oxidative stress, and its deficiency can cause severe physiological complications, including metabolic disorders, photosensitivity, anaemia, growth delay and gastrointestinal problems.

Arianna's Palette: A Diagnostic Study of the Painting Walls of the Domus of Arianna in Pompeii

Archaeometry, Volume 68, Issue 2, Page 261-273, April 2026.
ABSTRACT The House of Arianna, also known as the House of Colored Capitals, represents, with its 1700 m2 of floor space, one of the most majestic examples of a residence within the Pompeii archaeological site. The research developed within the project “Cultural Heritage Active Innovation for Sustainable Society—CHANGES” reports the outcomes of the ...

Leaf gas exchange measurement for steady‐state stomatal conductance model calibration

New Phytologist, Volume 250, Issue 1, Page 672-690, April 2026.
Summary Stomatal conductance models are essential components of crop and land surface models, but collecting data to calibrate them remains challenging due to large leaf‐to‐leaf variability, slow stomatal kinetics, and a lack of consistent measurement protocols, leading to unknown reliability and representativeness of calibrated model parameter ...

Epigenetic Modulation of the ACE System Underlies the Slow Aerobic Muscle Phenotype and Metabolic Exercise Response

The FASEB Journal, Volume 40, Issue 6, 31 March 2026.
Weekly moderate‐to‐vigorous activity (≈6 h) induced a marked increase in ACE promoter methylation in exercised knee‐extensor muscle. In combination with the ACE I/D genotype, ACE methylation contributed to ACE gene activity regulation in ways aligning with the slow‐twitch, aerobic muscle phenotype and its metabolic response to endurance exercise ...
