Sassolite Precipitation at the Restless Campi Flegrei Volcano in Italy Points to Hydrothermal Flashing by Deep Boron‐Rich Brines

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Studying the behavior of dormant volcanoes is a major challenge in volcanology. Here, we conducted a 10‐year survey of hydrothermal mineralization at Campi Flegrei, an active volcano near Naples in Italy, which last erupted in 1538. Our survey revealed a significant output of boric acid at the hydrothermal sulfate discharge area of Pisciarelli,

Non‐Invasive Diagnosis of Hypertrophic Cardiomyopathy by Breath

Advanced Sensor Research, Volume 4, Issue 7, July 2025.
The use of sensor technologies for the diagnosis of hypertrophic cardiomyopathy (HCM) by identification of volatile organic compounds (VOCs) in breath samples. By combining gas chromatography‐mass spectrometry (GC‐MS) and electronic nose (eNose) platforms, specific VOC patterns associated with HCM are detected and analyzed.

Numerical simulation on dynamic migration behaviour of radon of the exposed beach surface under non-isothermal conditions

Nuclear Engineering and Technology
Seasonal climate change profoundly affects radon release from uranium tailings beaches. This study evaluates radon migration in uranium tailings reservoirs by developing a non-isothermal radon migration model that incorporates freeze-thaw cycles.

Re‐assessment of the risks to public health related to the genotoxicity of styrene present in plastic food contact materials

EFSA Journal, Volume 23, Issue 6, June 2025.
Abstract The EFSA Panel on Food Contact Materials (FCM) was requested by the European Commission to re‐evaluate the potential genotoxicity of styrene after oral exposure and its safety for use in plastic FCM with a specific migration limit (SML) of 40 μg/kg food.
