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.

Researchers Crack the Code of How Fish Pick Their Own Birthday

10 December, 2024

New research has revealed that fish embryos actively control their hatching timing through a neurohormone, Thyrotropin-Releasing Hormone (TRH), which triggers the release of enzymes that dissolve the egg wall. This groundbreaking discovery uncovers a previously unknown neural mechanism that governs a critical life-stage transition, showing that embryos are not passive but instead actively make life-or-death decisions. The finding has significant evolutionary implications, offering new insights into neurobiology, survival strategies, and environmental adaptation in vertebrates.

Tiny Pseudoscorpion Rides on a Scorpion observed for the First Time

23 January, 2024

Researchers from the National Natural History Collections at the Hebrew University of Jerusalem and the Department of Evolutionary and Environmental Biology at the University of Haifa documented the first-ever observation of phoresy of pseudoscorpions on a scorpion host. This unique behavior sheds light on the intricate relationships of myrmecophile arachnids, particularly between the pseudoscorpion genus Nannowithius and the scorpion species Birulatus israelensis.
