Cigarette smoke causes cancer primarily by damaging the DNA. A new study that mapped the DNA damages caused by smoking, reveals that the way our DNA is organized and chemically modified can influence how cigarette smoke damages it, how well the damage is repaired and how many mutations will form. Specifically, areas of DNA that are more open and active are more prone to damage but also better at repairing themselves, which helps to prevent mutations.

Researchers have uncovered how egg cells prepare for the creation of life. Their work reveals the secrets of the Balbiani body, a remarkable structure that organizes essential molecules to guide early embryonic development. Using zebrafish models and cutting-edge imaging, the team discovered how this structure transforms from liquid droplets into a stable core, laying the groundwork for life itself. This discovery sheds light on the extraordinary precision of nature’s reproductive process. 

Israeli and Palestinian engineers from the Hebrew University of Jerusalem develop novel metamaterials for the cost-effective injection molding of whole cuts of meat. 

A study reveals that the structure of milk fat globules, rather than their chemical composition, plays a key role in their interactions with bacteria. Small globules promote the growth of beneficial bacteria like Bacillus subtilis, while larger ones trigger biofilm formation, a behavior linked to bacterial adaptation. These findings demonstrate milk’s natural protective mechanisms and highlight its potential to support gut health, offering significant implications for dairy science and nutrition.

A new study has uncovered a surprising link between Alzheimer’s disease and Herpes Simplex Virus-1 (HSV-1). Researchers found HSV-1 proteins embedded in Alzheimer’s brains, revealing how the virus is inhibited by tau protein—a key player in the disease. These insights could pave the way for innovative treatments targeting viral activity and the brain’s immune response to slow or even stop Alzheimer’s progression.

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.
