“Nightmare bacteria.” That’s how the CDC describes a frightening new threat spreading quickly in hospitals, communities and across the globe. FRONTLINE reporter David Hoffman investigates the alarming rise of untreatable infections: from a young girl thrust onto life support in an Arizona hospital, to a young American infected in India who comes home to Seattle, and an uncontrollable outbreak at the nation’s most prestigious hospital, where 18 patients were mysteriously infected and six died, despite frantic efforts to contain the killer bacteria.
Commonly known as “the cheese grater,” the Leadenhall Building is the pinnacle of London’s avant-garde architecture. Designed as a tapered tower with a steel exoskeleton, it’s the tallest skyscraper in the City of London and the most innovative. The teams behind the Leadenhall project had to radically rethink every aspect of the traditional building model. This program follows the monumental challenges that come with erecting this super skyscraper: it will be constructed off-site, delivered to location, and stacked and bolted together like a giant Lego set.
The dome that crowns Florence’s great cathedral of Santa Maria del Fiore — the Duomo — is a masterpiece of Renaissance ingenuity and an enduring source of mystery. Still the largest masonry dome on earth, it is taller than the Statue of Liberty and weighs as much as an average cruise ship. Historians and engineers have long debated how its architect, Filippo Brunelleschi, kept the dome perfectly aligned and symmetrical as the sides rose and converged toward the center. More than four million bricks could collapse at any moment — and we still don’t understand how Brunelleschi prevented it.
Why do some animals build structures and others don’t? And how do animals decide where to build? Animal homes need to be safe and secure, protected from predators and the weather. An eagle’s nest can weigh up to one ton, a termite mound can stand eight feet tall, and some falcon nest sites have been around for centuries. Going above ground and under, NATURE investigates just what goes into making a home when you’re wild and cost is not a factor.
