Technion to award the prestigious Harvey Prize to three groundbreaking researchers in cancer epigenetics

Prof. Stephen Baylin, Prof. Peter Jones, and Prof. Andrew Feinberg will receive the Harvey Prize for their groundbreaking work in cancer epigenetics, transforming our understanding of cellular function and disease progression. Their research has led to new diagnostic approaches and accelerated treatments targeting epigenetic mechanisms.

Parents’ childhood predicts future financial support for children’s education

A new study from Penn State found that parents who experienced difficult childhoods provided an average of $2,200 less for their children's college education. This suggests that intergenerational monetary exchanges could influence the next generation's success, with even parents' current socioeconomic status mattering.

New research reveals how the body clock regulates inflammation

Researchers at RCSI University of Medicine and Health Sciences have discovered that macrophages, a type of immune cell, work differently throughout the day due to the body's internal clock. This daily rhythm determines when immune cells are most efficient at detecting threats and mounts a response.
