Medical Xpress / Vitamin B3 therapy offers hope for fatal childhood disease

Scientists at Gladstone Institutes have flipped the traditional approach to finding potential treatments for deadly diseases. Instead of starting with a disease and hunting for a cure, they began with vitamins and systematically ...

Medical Xpress / Civilians face increasing harm from deadly explosive weapons, 17-country study finds

A University of Queensland study has found that almost 90% of people killed and injured by landmines and similar weapons are civilians. Dr. Stacey Pizzino from UQ's School of Public Health, together with her research team, ...

Medical Xpress / Vitamin B7 reveals a new metabolic weak spot in some cancers

A research group at the University of Lausanne (Unil) has identified a new mechanism that exposes the vulnerability of tumor cells when they are deprived of vitamin B7. The ability of cells to adapt to fluctuations in nutrient ...
