Wide and stubborn variations in longevity across Europe over past 20 years

The study analyzed 10-year survival rates among European populations aged 75-84 to see if they reached 85-94 years of age. Geographical variations in old age survival rates were found, with areas like Madrid and Salamanca in Spain showing high survival rates, while Glasgow and Manchester in the UK showed low survival rates.

Discovery lays the foundation to expand personalized chemotherapy for leukemia patients

A study led by St. Jude Children's Research Hospital scientists has identified four inherited NUDT15 gene variations that alter thiopurine metabolism, leaving patients sensitive to the drugs and at risk for treatment-disrupting toxicity. The research paves the way for personalized chemotherapy tailored to each patient's genetic makeup.
