Bacterial Movement Fuels the Spread of Antibiotic Resistance

Spinning Into Resistance: The Flagella’s Hidden Role

22 May, 2025

A new study from the Hebrew University of Jerusalem reveals that bacterial movement plays a central role in the transfer of antibiotic resistance genes. The research team discovered that the rotation of flagella in Bacillus subtilis acts as a mechanical signal that activates key conjugation genes. This enables donor bacteria to form clusters with recipients and successfully transfer DNA in liquid environments. The findings suggest that bacteria can use motion to control when and where gene sharing occurs, offering new insight into the spread of resistance across species.

How the Liver Remembers: The Science Behind Intermittent Fasting

10 December, 2024

A new study reveals how repeated fasting enhances the liver’s ability to adapt through a cellular memory mechanism. The research shows that alternate-day fasting “sensitizes” key genes and liver enhancers, boosting ketogenesis during subsequent fasting bouts. This process, driven by the transcription factor PPARα, highlights how the body adjusts to recurring nutritional challenges. These findings provide fresh insights into the metabolic benefits of fasting and its potential applications in health and dietary science.
