Our Galaxy’s Supermassive Black Hole has a few Hidden Friends

Astrophysicists set out to study supermassive black holes, the close relatives of Sagittarius A*, meandering throughout our galaxy. The mysterious galactic objects known as black holes help astrophysicists test the equations of general relativity...
New Study Suggests Adult Human Brain Still Creates Nerve Cells

New Study Suggests Adult Human Brain Still Creates Nerve Cells

Researchers discovered that, contrary to previous assumptions, an adult human brain is still capable of creating nerve cells. For years, scientists believed that the adult human brain no longer produces new brain cells. However, a recent study...
