Discovery’s Edge

91��ݮ��Ƶ scientists revolutionize our understanding of land, sea, space, and the human body.

December 5, 2024

Scale is everything. Some mysteries require us to look up, toward the cosmos. Others demand we look down, into microscopic worlds. Still others ask us to look around—at our changing forests, warming oceans, and dynamic bodies. The scientists featured here pursue understanding across these vast scales, finding unexpected connections between the very large and very small. Their work reveals how tree canopies, ocean spray, black holes, and brain cells alike help tell the story of our universe and our place within it.
