Medicine has come a long way since the days of using leeches to heal people. Magnetic resonance imaging (MRI) machines are one of the greatest marvels of medical science, and the way they work is something out of a sci-fi movie.

Over on my Instagram page, I share photos of my life. I keep my profile private, but I'll add you!

The trailer for "Indiana Jones and the Dial of Destiny" is out and it's turning a lot of heads. There are short glimpses of a young Harrison Ford, and it's not archival footage. It's actually a whole new CGI technology created just for this movie. But how does it work?

Magnets can lift heavy objects and create strong electrical fields. They are truly a marvel of modern science and technology. But how strong can they get? Get ready to be amazed by the strength and capabilities of the strongest magnets humans have ever made.

What does it mean for something to be the color black? Simply put, it's when light cannot be reflected by an object. You might be surprised to learn that scientists have been searching for ways to create the blackest black in the world. It turns out super black paints can change the science world.
