No matter how you think of it, your skin is very important. It covers and protects everything inside your body. In humans, it is the largest organ of the integumentary system.
Graphene is the most promising new material out there, likely to revolutionize the way we do or build almost anything. It’s pure carbon, and totally amazing. Trace shows us all the different ways this material could change life on Earth.
The early universe was sizzling with active galactic nuclei (AGN) — intensely luminous cores powered by supermassive black holes — most of which could outshine their entire host galaxies and be seen across the observable universe.
While our central supermassive black hole Sgr A* lies rather dormant at the moment, new evidence suggests that it too was once a powerful AGN.
