Quoted: At an experimental Web site, Many Eyes, users can upload the data they want to visualize, then try sophisticated tools to generate interactive displays. These might range from maps of relationships in the New Testament to a display of the comparative frequency of words used in speeches by Senators Hillary Rodham Clinton and Barack Obama.

Quoted: Many a professor dreams of revolution. But Norman T. Uphoff, working in a leafy corner of the Cornell University campus, is leading an inconspicuous one centered on solving the global food crisis. The secret, he says, is a new way of growing rice.

click to playGlucocorticoids are steroids produced by bodies at times of stress. Prolonged stress(and exposure to the steroids) damages hippocampus neurons. PTSD and depression(ie chronic stress) can cause permanent damage to the hippocampus, slow neurogenesis and affect memory.
From studies of baboon clans, this steroid level-
(a) is generally low in high ranking males and high in low ranking males. They are high for high-ranking males when the societal hierarchy is under threat.
(b) is high when the personal threat is unpredictable and arbitrary.
(c) is higher when a baboon is unable to distinguish a real threat from a non-threat.
(d) is lower where baboons have a social outlet for anger.
(e) is lower when they are sociable and not alone.ShareViewed: 12 Times

Dr. Pausch's speech was more than just an academic exercise. The 46-year-old father of three has pancreatic cancer and expects to live for just a few months. His lecture, using images on a giant screen, turned out to be a rollicking and riveting journey through the lessons of his life.

Quoted: A nationwide trend for universities to use adjunct professors instead of a tenured faculty has become so extreme that some schools are pulling back... Several studies of individual universities have determined that freshmen taught by many part-timers were more likely to drop out.
Quoted: The lack of tenure can leave adjuncts vulnerable. In a number of cases, professors outside the tenure track have been dropped after run-ins with administrators over everything from grading to opinion articles in newspapers.

Quoted: Being poor sucks," Lisi says. "It's hard to figure out the secrets of the universe when you're trying to figure out where you and your girlfriend are going to sleep next month."
Quoted: Lisi's inspiration lies in the most elegant and intricate shape known to mathematics, called E8 - a complex, eight-dimensional mathematical pattern with 248 points first found in 1887, but only fully understood by mathematicians this year after workings, that, if written out in tiny print, would cover an area the size of Manhattan.
Here is the paper for you theoretical physicists out there- http://www.arxiv.org/abs/0711.0770

Quoted: To get a sense of swarms, Dr. Couzin builds computer models of virtual swarms. Each model contains thousands of individual agents, which he can program to follow a few simple rules. To decide what those rules ought to be, he and his colleagues head out to jungles, deserts or oceans to observe animals in action.
