Body size of male Atlantic salmon (Salmo salar L.) at introduction of a 5‐week LD12:12 winter signal influences their decision to mature early or smoltify

open access: yesJournal of Fish Biology, EarlyView.
Abstract Sexual maturation of male Atlantic salmon post‐smolts (‘jacking’) is undesired in aquaculture and seems to occur due to the intensification in modern facilities. Maturation depends on internal and external factors (temperature, photoperiod, feed availability, energy levels, body size, genetic background) that act on the brain‐pituitary‐gonad ...

Flexible Inkjet-Printed pH Sensors for Application in Organ-on-a-Chip Biomedical Testing

open access: yesBiosensors
Reliable models of the lung environment are important for research on inhalation products, drug delivery, and how aerosols interact with tissue. pH fluctuations frequently accompany real physiological processes in pulmonary environments, so monitoring pH

Early acclimatization to high altitude: Acid–base and fluid balance dynamics during the first 2 days at 3100 m

open access: yesExperimental Physiology, EarlyView.
Abstract Immediate responses to hypoxia at high altitude are hyperventilation and successive respiratory alkalosis. Alkalosis, in turn, can affect cerebrospinal fluid pH and ventilatory control. The kidneys compensate metabolically for respiratory alkalosis.

At‐Home Early Diagnosis of Mastitis: Calibration‐Free Analysis of Sodium to Potassium Ratio in Breast Milk

open access: yesAdvanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
MAMAWEL is introduced as the first calibration‐free potentiometric sensor for at‐home mastitis diagnosis. By measuring the sodium‐to‐potassium ratio in breast milk, the device reliably differentiates between healthy and mastitis‐affected samples with less than 10% error.

Integrated Flexible Zwitterionic Electrochemical Sensor Platform for Real‐Time Salivary Glucose Quantification

open access: yesAdvanced Sensor Research, Volume 5, Issue 2, February 2026.
A flexible electrochemical sensor platform can enable continuous, real‐time monitoring of salivary glucose for applications confined to spaces such as the oral cavity. Surface modifications with Prussian blue, chitosan, and zwitterionic polymers enhance sensitivity, selectivity, and antiadherent performance.

Photon‐to‐Heat Energy Harvesting Fluorescent Protein Coatings for Thermoelectrics

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
Fluorescent proteins (FPs) are used in light‐absorbing coatings on thermoelectric generators (TEGs) to convert light into heat and generate electricity. By tuning the properties of FP‐doped polymer matrices, photothermal efficiencies of up to 48% have been achieved.
