A new study reveals that typically developing twins consistently take on the dominant role over their nontypically developing siblings, even after developmental gaps are resolved. By highlighting how parental perceptions shape these dynamics, the research offers fresh insights into the delicate balance of twin relationships and the importance of fostering equality to support both children’s growth. 

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.

The horrific attack by Hamas on Israeli civilians on October 7, sparked the Iron Swords War and led to a widespread mobilization effort to support Israel. New survey revealed that 83% of the NGOs’ ability to provide assistance and social services was negatively impacted by the war, only 35% of organizations sought government assistance during the war, and 35% of the NGOs reported an increase in philanthropic support from abroad.

New study suggests that low-level laser therapy (PBM) offers immediate pain relief for Burning Mouth Syndrome (BMS) patients. Over 10 weeks, 30 participants experienced a significant drop in pain scores after each treatment. While efficacy decreased in the following week, a cumulative effect was observed, especially up to the third treatment. The findings highlight the potential of PBM as a promising treatment for BMS, despite some nuances in its effectiveness.

The Hebrew University has appointed Prof. Orly Sade as the new Dean of the School of Business Administration. Prof. Sade brings extensive experience and expertise to her new role, with a focus on analytical and experimental finance, financial market structure, fintech, and crowdfunding.
