Textile artist Magda Sayeg transforms urban landscapes into her own playground by decorating everyday objects with colorful knit and crochet works.

"We all live in this fast-paced, digital world, but we still crave and desire something that's relatable," Sayeg says. "Hidden power can be found in the most unassuming places, and we all possess skills that are just waiting to be discovered."

What would it be like to have a limitless memory? Can the meaning of life be found in an infinite library? Is time a labyrinth or a single moment?

It's an incredible discovery: an abandoned alien space station filled with precursor technology. Now every species in the galaxy is in a mad dash to get there first, but you've got a problem.

In the 16th century, an anatomist named Andreas Vesalius made a shocking discovery: the most famous human anatomy texts in the world were wrong. While Vesalius knew he was right, announcing the errors would mean challenging Galen of Pergamon. Who was this towering figure?
