More Information: What’s a little confusing about the data given above is that obviously, our brains grow bigger after birth, and so do our hearts. So where is all the extra bulk coming from? In the brain, no cerebral cortex neurons are added, but research hasn’t been completed on other parts of the brain, and even if it were to turn out that no other neurons are added, lots of other kinds of cells are added. Glial cells, for example, may actually make up 90% of the cells in the brain. It used to be thought that glial cells were simply the scaffolding of the brain, with no real role in the processing of the brain. In recent years, however, it has become clear that glial cells play key roles in processing.

It’s Hot, and These First Graders Are Bothered: the Use of DocumentCloud
Beware the fury of a first grader scorched.
Document Cloud
“We need an air conditioner we are dieing pleause let us have a air conditioner,” Nicole Mei wrote. “We can’t read if we are so hot water/are going to be in our eyes. if we don’t have one I can’t write, read or listen.”

U.S. Underwrites Internet Detour Around Censors
The Obama administration is leading a global effort to deploy “shadow” Internet and mobile phone systems that dissidents can use to undermine repressive governments that seek to silence them by censoring or shutting down telecommunications networks.
The effort includes secretive projects to create independent cellphone networks inside foreign countries, as well as one operation out of a spy novel in a fifth-floor shop on L Street in Washington, where a group of young entrepreneurs who look as if they could be in a garage band are fitting deceptively innocent-looking hardware into a prototype “Internet in a suitcase.”

Professor Karen Willcox, member of the MIT faculty
Professor Karen Willcox, a member of the MIT faculty since 2001, has been teaching undergraduate courses in aeronautics and astronautics every year since she arrived at MIT.
"My sense is that OCW will really enable us to create better educational linkages, and to fully integrate the learning experience."
"I really had the impression that all the students would just be fantastic in math," explains Willcox. "When I realized this was not the case, the first thing I did was to try to understand the source of the problem. I started talking to the math faculty and I realized that there was this disconnect between the math and engineering departments."
