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 at the Hebrew University enhanced the Elixhauser Comorbidity Model, improving predictions for length of hospital stay, mortality, readmission, and escalated care. The study outperformed the standard Elixhauser model, offering a comprehensive view of patient complexity. These findings benefit healthcare decisions and patient outcomes, with broad implications for the field.

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.

A recent study has developed a novel method to analyze genetic variations in families with a high incidence of breast cancer. By examining 1218 genetic variants in 12 families, the research identified 80 genes linked to an increased risk of the disease. It also highlighted the significant, yet previously overlooked, roles of peroxisomal and mitochondrial pathways in breast cancer predisposition and patient survival.

A new study highlights the potential of psilocybin, a psychedelic compound, in treating obsessive-compulsive disorder (OCD) and Tourette’s Syndrome. Research conducted on mice showed that psilocybin and psychedelic mushroom extract significantly reduced OCD-like behaviors and tic-like head-body twitches. These promising results pave the way for clinical trials and offer hope for new, effective treatments for OCD and Tourette’s Syndrome.

A new perspective work reveals insights into the development of bacterial biofilms, highlighting how these communities adapt to environmental stress through complex interactions between physical and biological processes occurring in the surrounding environment. The research could have broad implications for fields such as medicine, environmental science, and industry.

New research from Hebrew University shows that how well parents understand their children and manage their own emotions greatly affects homework time. Parents who are good at understanding their kids are more supportive and help them become more independent and motivated to learn. On the other hand, parents who have trouble managing their emotions are more likely to act negatively, which can make it harder for children to stay engaged and do well in their learning.

The Hebrew University of Jerusalem proudly congratulates five of its esteemed researchers for receiving prestigious European Research Council (ERC) Starting Grants. These grants, each valued at approximately 1.5 million euros, are awarded to young researchers at the early stages of their careers, specifically those with 2-7 years of research experience since completing their PhDs.

A new study has identified key factors influencing vaccination intentions among Israeli dairy farmers. By comparing five diseases affecting dairy cattle, the research highlights the significant impact of social pressure and underscores the need for improved communication between veterinarians and farmers to optimize voluntary vaccination programs. These findings are crucial for enhancing epidemic control and ensuring the health and productivity of dairy farms.
