Is the Web Out of Room?

Each device that connects to the Internet is assigned an I.P. address, but we are quickly approaching the numerical 4.3 billion limit. The Daily Beast on possible solutions.

The problem boils down to a real-estate shortage. Specifically, there’s a scarcity of Internet addresses, the critical and unique numbers that are used to distinguish one computer from another. ... If you do the math, you quickly find out that system offers roughly 4.3 billion possible I.P. addresses. That’s a lot of addresses. But we’ve also been hooking up a lot of things to the Internet, all over the world. ... For companies in the U.S., IP addresses are parceled out by the American Registry for Internet Numbers.

Why is 18 the age of adulthood if the brain can take 30 years to mature?

Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.

Mind & Brain
  • Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
  • Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take pace well into one's 20s.
  • The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.
