The Canadian superstar opened up about her life altering neurological disorder during her emotional sit down interview with NBC's Hoda Kapi Tuesday night. The 56 year old singer says she was prescribed Valium to cope with her symptoms, but began taking progressively higher doses to get her through her shows. It took more than a decade of testing and treatments for Dion to get the official diagnosis and in 20/22 she felt her fans deserve to know what she was dealing with. Singer Kevin Jonas says he's received treatment for skin cancer. Sharing his experience on Instagram, Jonas says he spotted a small mole on his forehead and was diagnosed with basal cell carcinoma.

Reliable use of PPE is of high importance when responding to disasters. New research is giving us insight into the impact of space tourism on the body.
