At STREB Action Lab, Dance and Physics Collide
Choreographer Elizabeth Streb pushes the boundaries of Newtonian physics--with dance. In her show Forces, dancers fly, fall, and collide in mid-air. No wonder the "action architect" has her share of scientist fans, among them, big-thinking particle physicist Lisa Randall.
Eating 'Wilder' Foods for a Healthier Diet
In Eating on the Wild Side, author Jo Robinson reveals how the nutrition and flavor has been bred out of supermarket fruits and vegetables. Robinson tells us what we can do to reclaim our wild roots and the nutrition from our foods.
Annual Prizes Honor the Stranger Side of Science

When Water Flows Uphill
In the Leidenfrost Effect, a water droplet will float on a layer of its own vapor if heated to a certain temperature. This common cooking phenomenon takes center stage in a series of playful experiments by physicists at England's University of Bath, who discovered new and fun means to manipulate the movement of water.
How to Avoid 'Food Failures' This Thanksgiving
