Can we improve medical devices by designing them to translate the language of the body? Materials scientist Canan Dagdeviren, who just launched a new research group at MIT, thinks so. Ever since she was a child growing up in Turkey, she’s turned tragedy and loss into research that speaks to hope.
Her inventions suggest that scientists can harvest electricity from the movements of our organs, pick up the first hints of disease from subtle changes in physiological patterns, or track changes ...read more
Our relationship with yeast is like a college friendship that grew beyond keggers and into distinguished adulthood. We’ve partied with our eukaryotic wingmen dating back to at least 7000 B.C., using them in foods and head-spinning libations. In 1680, Anton van Leeuwenhoek, godfather of microscopy, gazed upon yeast for the first time; that’s when we started moving past the party years.
We still throw down with yeast, but we’ve grown up and have jobs now. These days, the fungus i ...read more

1. Yoga today is a mainstream fitness activity; 1 in 5 American adults participates in what most people believe is an ancient practice. Surprise: The yoga you’re going to the mat for isn’t that old.
2. What we generally think of as yoga began in late 19th century India, when leaders of an anti-colonialism movement sought to rally their countrymen to their cause.
3. Some of these men saw yoga, then more of a philosophy, as a non-sectarian, indigenous symbol of India that transcended d ...read more

You're almost there.
Forget reality: In virtual reality, you can be whomever and wherever you want. VR makes the unreal real, using computer software and hardware that responds to our body’s movements to immerse us in a convincing alternate existence. There’s plenty of space to roam. VR places can be huge. In Second Life, an early pioneer of virtual worlds, you can attend university, own a blimp, have blue fur — whatever. It includes more than 600 square miles of otherworl ...read more

See the light on dark matter and dark energy.
Say the universe is a restaurant entrée. Astonishingly, everything that we can discern on the plate, so to speak — protons, paramecia, people, planets, pulsars, you name it — altogether adds up to a mere sprig of parsley. To a cosmic garnish such as ourselves, the vast majority of the universe is invisible, an empty plate dominated by “dark” matter and a “dark” energy. The effects of these phenomena are ...read more
Communities of tiny plants and organisms protect arid landscapes. Now their survival is threatened.
On a cool September morning, a caravan of international scientists rumbles past the iconic formations of Canyonlands National Park in Utah. Over the eons, wind and water have carved this landscape into a maze of stunning red sandstone arches and spires. The researchers marvel at the formations, so different from their own backyards — places as distant as China, Niger, Australia and Spai ...read more
Our early solar system was a wild place. Dust grains grew into pebbles, and pebbles became world-building planetesimals. These rocks spun around and bumped into each other in a chaotic dance that left a trail of debris in its wake. The remnants of these festivities remain strewn about our cosmic backyard. Many rocky and metallic bodies now orbit in what’s called the Main Asteroid Belt, between Mars and Jupiter.
More than just leftovers, asteroids offer clues to the earliest days of our sol ...read more
