Welcome to the Collaboration Age, where even the youngest among us are on the Web, tapping into what are without question some of the most transformative connecting technologies the world has ever seen. These tools are allowing us not only to mine the wisdom and experiences of the more than one billion people now online but also to connect with them to further our understanding of the global experience and do good work together. These tools are fast changing, decidedly social, and rich with powerful learning opportunities for us all, if we can figure out how to leverage their potential.

Most of the brain's wiring is established during the first few years of life. At birth it was only about a quarter of its eventual adult size. But by age 2, it has reached three-fourths of adult size! And by 5, the brain will be very close to adult size and volume.

Surprisingly, the brain of a 2-year-old has trillions of connections — double the number that an adult has! The brain grows connections in response to all kinds of input in order to adapt and survive. Over time, certain connections are used again and again while others fall by the wayside

For middle-aged and older adults, searching the Internet could be a boost to the brain, a new study suggests.

The new study suggests a possible association between the two, because elevated blood sugar appears to damage the dentate gyrus, Small says.
