Sharon Roseman was five years old when her world changed forever. She was playing Blind Man's Bluff-a game of tag in which the "it" person is blindfolded-with friends outside her house. When she removed her blindfold, she couldn't recognize where she was. “My street was not my street, my house was not my house," she says. "I was in this totally unfamiliar place that I had never seen before, and it scared me to death." It was only the beginning. From that moment on, Roseman has been lost every day of her life.
Lost Even in Familiar Places
Such a turn of events might sound like an episode of The Twilight Zone. But Roseman's story is true, and she is not alone in her bizarre and frightening experience. As an adult living in Denver, Colorado, in 2008, Roseman was diagnosed with a rare and newly discovered condition called Developmental Topographical Disorientation. DTD is a disorder that dramatically affects people's abilities to navigate their environment. “It's almost as if somebody picks up the entire world, turns it, and sets it back down,” Roseman explained to the New York Times in 2013.
The condition typically first appears in childhood. People with DTD have no underlying brain condition or injury. Yet they experience severe orientation problems all their life and get lost even in places where they spend a lot of time, like their home and school. When Roseman would check on her own babies in the night, she would frequently bump into walls, not realizing they were there.
Dr. Giuseppe Iaria of the University of Calgary in Canada is credited with first identifying DTD. He confirms that odd as it sounds people with DTD have no underlying neurological conditions or brain damage. He thinks genetic factors are likely responsible for this malady.

Who's Your Cousin?
The great apes are among the most popular animals in most zoos. Their actions, facial expressions, and family life remind us so much of ourselves. Have you ever wondered, though, how we might look to them?
Is it possible to die of boredom?
To figure out if we can die of boredom, we first have to understand what boredom is. For help, we called James Danckert, a psychologist who studies boredom at the University of Waterloo in Canada.

THE LEFT OVERS
A lot has happened for modern humans to get to this point. We lost most of our hair, learned how to make tools, established civilizations, sent a person to the Moon, and invented artificial intelligence. Whew! With all of these changes, our bodies have changed, too. It’s only taken us about six million years.
SO, WHAT IS A PRIMATE?
What do you have in common with the aye-aye, sifaka, siamang, and potto? If you said your collarbone, you re probably a primatologist—a person who studies primates. If you’re not, read on.
