Novel nanoparticle enhances radiation tumor killing

Radiation kills tumors by creating oxygen free radicals that damage the tumor DNA. However, the lack of oxygen in the center of tumors blocks the production of free radicals, inhibiting radiation killing. NIBIB researchers ...

Damaged protein could be key to premature ageing

(Medical Xpress)—Scientists have found that the condition of key proteins in the mitochondria -the batteries of cells- could be used to predict, and eventually treat premature ageing. And restricting diet could be one way ...
