The World of Seven Billion The map shows population density; the brightest points are the highest densities. Each country is colored according to its average annual gross national income per capita, using categories established by the World Bank (see key below). Some nations— like economic powerhouses China and India—have an especially wide range of incomes. But as the two most populous countries, both are lower middle class when income is averaged per capita.
Snapshot from video NOTE: Some major wind projects like the proposed TWE Carbon Valley project in Wyoming are already pricing in significantly lower than coal power -- $80 per MWh for wind versus $90 per MWh for coal -- and that is without government subsidies using today's wind turbine technology. The International Clean Energy Analysis (ICEA) gateway estimates that the U.S. possesses 2.2 million km2 of high wind potential (Class 3-7 winds) — about 850,000 square miles of land that could yield high levels of wind energy.

Written in Bone - A Highly Unusual Case
In 2002, archaeologists uncovered an isolated grave just outside the log wall of a fort built on an island in the James River almost four centuries earlier. Who was buried there? Male skeleton (burial partially re-created for an exhibition) 1607, James Fort site, Jamestown Virginia.Backing out of the nanotunnel
ScienceDaily (Jan. 10, 2012) — In the world of biomolecules such as proteins and the hereditary nucleic acids DNA and RNA, three-dimensional structure determines function. Analysis of the passage of such molecules through nanopores offers a relatively new, but highly promising, technique for obtaining information about their spatial conformations.
The Very Large Array, one of the world's premier astronomical radio observatories, consists of 27 radio antennas in a Y-shaped configuration on the Plains of San Agustin fifty miles west of Socorro, New Mexico. Each antenna is 25 meters (82 feet) in diameter.

Who We Are NASA's Chandra X-ray Observatory is a telescope specially designed to detect X-ray emission from very hot regions of the Universe such as exploded stars, clusters of galaxies, and matter around black holes. Because X-rays are absorbed by Earth's atmosphere, Chandra must orbit above it, up to an altitude of 139,000 km (86,500 mi) in space. The Smithsonian's Astrophysical Observatory in Cambridge, MA, hosts the Chandra X-ray Center which operates the satellite, processes the data, and distributes it to scientists around the world for analysis. The Center maintains an extensive public web site about the science results and an education program. What We Do

The Webb Space Telescope, Hubble's successor, will see in infrared, the light emitted by the farthest objects we can detect. Learn about Webb, its technology, and the science it will reveal.

What is fracking? Fracking or hydraulic fracturing is a method utilized by oil and gas companies to increase production of oil or gas from a well that would otherwise exhibit a low flow rate usually due to the geologic rock formation being too dense to allow for the economic recovery of hydrocarbons.
