This study introduces a paper‐based biodegradable, humidity‐insensitive e‐nose for real‐time breath analysis, addressing challenges in existing technologies such as humidity interference, high costs, and environmental impact. Featuring hydrophobic polymer coatings, these sensors reliably detect VOCs even in high‐moisture environments.

Emerging roles for microRNA in the regulation of Drosophila circadian clock
Background The circadian clock, which operates within an approximately 24-h period, is closely linked to the survival and fitness of almost all living organisms. The circadian clock is generated through a negative transcription-translation feedback loop.

Cell-autonomous clock of astrocytes drives circadian behavior in mammals
Astrocytes can drive the master clock in the brain The neurons of the suprachiasmatic nucleus (SCN) of the hypothalamus function as a central circadian clock, coordinating mammalian physiology with the 24-hour light-dark cycle. Brancaccio et al.

This study introduces a controllable degradation system for Mg‐based biomaterials using sputtering technology, marking a significant advancement in nerve regeneration research. The Mg‐sputtered nerve conduits demonstrate enhanced biocompatibility, biofunctionality, mechanical compatibility, and precise magnesium release, resulting in improved axonal ...

Circadian clocks optimally adapt to sunlight for reliable synchronization [PDF]
Circadian oscillation provides selection advantages through synchronization to the daylight cycle. However, a reliable clock must be designed through two conflicting properties: entrainability to synchronize internal time with periodic stimuli such as sunlight, and regularity to oscillate with a precise period.

New Perspectives on Semiconducting Conjugated Oligomers for Neuromodulation in Hydra vulgaris
Semiconducting organic compounds, thiophene‐based, modify the rhythmic electrical activity of the cnidarian Hydra vulgaris acting on specific neuronal circuits. The ETE‐S trimer also forms electronically conducting wires in the living tissues of the animal.

Disrupting circadian homeostasis of sympathetic signaling promotes tumor development in mice. [PDF]
Cell proliferation in all rapidly renewing mammalian tissues follows a circadian rhythm that is often disrupted in advanced-stage tumors. Epidemiologic studies have revealed a clear link between disruption of circadian rhythms and cancer development in ...

The Circadian Clocks of Mice and Men [PDF]
Major strides have been made toward understanding the molecular mechanism of rodent clocks. But how far do those steps carry us toward understanding circadian clock function in humans? Practical advances in human genetics, not the least of which is the availability of a virtually complete genome sequence, now allow animal research to be complemented by

Epileptiform Activity and Seizure Risk Follow Long‐Term Non‐Linear Attractor Dynamics
This study leverages the HAVOK framework to model long‐term, nonlinear attractor dynamics underlying epileptiform activity and seizure risk in epilepsy patients. By identifying key forcing mechanisms driving chaotic transitions, the findings improve seizure risk forecasting over multi‐day cycles and provide a pathway for personalized, data‐driven ...

Circadian Rhythms in the CNS and Peripheral Clock Disorders: The Circadian Clock and Hyperlipidemia
A circadian clock controls various physiological and behavioral rhythms. In mammals, a master circadian clock exists in the suprachiasmatic nucleus of the hypothalamus, and slave oscillators can be found in most tissues.
