2011 Science News of the Year: Life
Multicellular life from a test tube In less than two months, yeast in a test tube evolved from single-celled life to bristly multicellular structures. The new, snowflakelike forms act like multicellular organisms, reproducing by splitting when they reach large sizes and evolving further in response to harsh conditions, William Ratcliff of the University of Minnesota, […]

2011 Science News of the Year: Technology
Courtesy of J. Rogers Epidermal electronics Scientists have created an ultrathin electronic device that puckers, stretches, wrinkles and bends just like human skin (SN: 9/10/11, p. 10). This flexible patch could one day allow the human body to enter the digital world, enabling Internet browsing without the mouse or communication without words. The patch’s electronics […]
