GALAXY WITHOUT DARK MATTER CHALLENGES CURRENT SCIENCE
Amateur stargazers like me find it hard to locate galaxies in the night sky. I guess we shouldn’t be too hard on ourselves, since the existence of other galaxies only came to light about 100 years ago.

DYING BRAINS MAY EXPERIENCE SURGE OF CONSCIOUSNESS
My mother passed away about three years ago, and we, her children and grandchildren, were at her bedside when she passed away. It was a painful, yet profound experience for everyone including, I like to believe, for my mother herself.
