Echoes of Selma - CNN.com They never linked arms to sing "We Shall Overcome." No one smacked them on the head with a club for trying to vote. They didn't march into a phalanx of armed state troopers who beat them like animals. But the forces that mobilized against demonstrators in Selma, Alabama, 50 years ago launched a movement of their own that relied on an audacious strategy: They blew a hole through the civil rights movement's most revered law by borrowing the same tactics protesters used in Selma. These Maps Show You How to Live, Not Just Where Data for GOOD Knowledge is the first step on the way to progress. It used to be that paper maps were the free gifts that came with your new compass, graphically representing geography via points, lines, and fire-breathing dragons—all of which indicated orientation, distance, latitude, longitude, and the sheer vastness of uncharted territory. But today’s multidimensional digital maps are comprehensive, interactive, and they’ve got the compass built right in. Plus, they’re changing the way we interact with our environments and with each other.

The Human Journey: Migration Routes When humans first ventured out of Africa some 60,000 years ago, they left genetic footprints still visible today. By mapping the appearance and frequency of genetic markers in modern peoples, we create a picture of when and where ancient humans moved around the world. These great migrations eventually led the descendants of a small group of Africans to occupy even the farthest reaches of the Earth. Our species is an African one: Africa is where we first evolved, and where we have spent the majority of our time on Earth. The earliest fossils of recognizably modern Homo sapiens appear in the fossil record at Omo Kibish in Ethiopia, around 200,000 years ago. Although earlier fossils may be found over the coming years, this is our best understanding of when and approximately where we originated.

What’s the prime of your life? Do you ever worry that the prime of your life has already passed you by – and it didn’t even have the courtesy to let you know as it flew overhead? They say that life begins at 40, or that 60 is the new 50 – but what’s the truth? What’s the best age to be? Pentagon withheld information about decades-old chemical weapons during Iraq War, report claims This photo shows the interior of a chemical weapons facility in Iraq (AP) American troops were exposed to chemical weapons multiple times in the years following the 2003 invasion of Iraq, while the Pentagon kept their discoveries of the expired or degraded weapons secret from investigators, fellow soldiers, and military doctors, according to a published report. The New York Times reported late Tuesday that American troops reported finding approximately 5,000 chemical warheads, shells, or aviation bombs in the years following the 2003 invasion of Iraq. On at least six occasions, soldiers were wounded by those weapons, which had been manufactured before 1991. In all, the paper reported that 17 U.S. soldiers and seven Iraqi police officers were exposed to chemical agents during the war.

Pollution Locator: USA Over 4 billion pounds of toxic chemicals are released by industry into the nation's environment each year, including 72 million pounds of recognized carcinogens. Scorecard can give you a detailed report on chemicals being released from any of 20,000 industrial facilities, or a summary report for any area in the country. Scorecard spotlights the top polluters in the U.S., and ranks states and counties by pollutant releases. The Origin of Humans Is Surprisingly Complicated HUMAN FAMILY TREE used to be a scraggly thing. With relatively few fossils to work from, scientists' best guess was that they could all be assigned to just two lineages, one of which went extinct and the other of which ultimately gave rise to us. Discoveries made over the past few decades have revealed a far more luxuriant tree, however—one abounding with branches and twigs that eventually petered out.

In the heart of every parent lives the tightly coiled nightmare that his child will die. It might spring at logical times—when a toddler runs into the street, say—or it might sneak up in quieter moments. The fear is a helpful evolutionary motivation for parents to protect their children, but it's haunting nonetheless. This Week in Sociology: Unintended Consequences: The Social Context of 9/11 by Mike King, University of California, Santa Cruz, September 11, 2001 is a world historic moment, a historical signpost – “9/11”. More than a deadly attack, it stands as a moment that truly changed history, and its existence--not only in memory but in remembrance—can help us understand both the past and the present. Last week marked the tenth anniversary of this moment. Of the myriad memorials, documentaries, and assorted tributes, however, few addressed the root causes of the event or the complex and contradictory context of its impact afterwards. What does 9/11 really tell us about the politics of our past and our contemporary memories?
