A report of the research, "A Genetic Atlas of Human Admixture History," is revealed in Science, February 13, 2014. The interactive map, produced by researchers from Oxford University and the University College London (UCL), details the histories of genetic mixing between each of the 95 populations across Europe, Africa, Asia and South America spanning the last four millennia. You can check out the admixture atlas here.

Earthquakes can come in three main forms, depending on the plate movements that occur beneath the earth's surface. They could occur on a Convergent Boundary, Divergent Boundary or a Transform Fault. Convergent boundary: Here, one plate is forced over another plate during movement creating a thrust fault.

*Creating Earthquake Heat Maps: Temperature Spikes Leave Clues in the Rock Lamont Associate Research Professor Heather Savage explains how scientists are using biomarkers and temperature to locate past earthquake activity. When you rub your hands together to warm them, the friction creates heat. The same thing happens during earthquakes, only on a much larger scale: When a fault slips, the temperature can spike by hundreds of degrees, high enough to alter organic compounds in the rocks and leave a signature. A team of scientists at Columbia University’s Lamont-Doherty Earth Observatory has been developing methods to use those organic signatures to reconstruct past earthquakes and explore where those earthquakes started and stopped and how they moved through the fault zone. The information could eventually help scientists better understand what controls earthquakes.

Survival of the ... Nicest? Check Out the Other Theory of Evolution by Eric Michael Johnson A new theory of human origins says cooperation—not competition—is instinctive. posted May 03, 2013 A century ago, industrialists like Andrew Carnegie believed that Darwin’s theories justified an economy of vicious competition and inequality. They left us with an ideological legacy that says the corporate economy, in which wealth concentrates in the hands of a few, produces the best for humanity. More Evidence that the Moon Contributes to Earthquakes An almost-full, half-pie, waxing moon hanging lopsided in the night sky has long been a symbol of things to come. Now scientists have a new symbolism for the lunar phase we call first quarter: a looming risk of earthquakes. The moon is (mostly) responsible for Earth’s tides, which are strongest when the sun and moon are aligned, during a full moon or a new moon. It’s small, the moon, but so close that its gravity stretches and compresses the water across the globe, into high and low tides called spring and neap tide, respectively. It pulls on the Earth’s crust, too, but only a tiny bit, especially compared to the breath-like rise and fall of an ocean. Still, scientists have wondered for years whether the moon might play a role in earthquakes, which are essentially movements of the Earth’s crust atop its mantle.

The 10 deadliest earthquakes in history - World news - Asia-Pacific A look at the worst earthquakes in recorded history, in loss of human life. (The March 11, 2011, earthquake and tsumani that affected eastern Japan is not included because the fatalities caused, about 15,000, are fewer than those resulting from the temblors listed below.) Sources: United States Geological Survey, Encyclopedia Britannica 1: Shensi, China, Jan. 23, 1556 Magnitude about 8, about 830,000 deaths. This earthquake occurred in the Shaanxi province (formerly Shensi), China, about 50 miles east-northeast of Xi'an, the capital of Shaanxi. More than 830,000 people are estimated to have been killed. Damage extended as far away as about 270 miles northeast of the epicenter, with reports as far as Liuyang in Hunan, more than 500 miles away.

Digital Typhoon: Typhoon Images and Information - National Institute of Informatics This site has the comprehensive archive of meteorological satellite "Himawari" images since 1978, and offers a typhoon database of about 200,000 typhoon images since 1979 and typhoon best tracks since 1951 to search by date, name, location, cloud patterns, and so on. Recently this site started to provide typhoon forecast information, but the latest typhoon information, weather forecast, advisories and warnings should be obtained from reliable sources such as "Japan Meteorological Agency: Typhoon Information" and other sites. Updates may be delayed due to the status of network between data sources. Images of past typhoons from 1979 to this year are archived. In the informatics community, there is a growing interest in discovering relevant information from the huge amount of data that is overwhelming even in our everyday life.

Can Asteroids, Meteorites or Man-Made Explosions Cause Tsunamis? - International Tsunami Information Center Fortunately, for mankind, it is indeed very rare for a meteorite or an asteroid to reach the earth. Although no documented tsunami has ever been generated by an asteroid impact, the effects of such an event would be disastrous. Most meteorites burn as they reach the earth's atmosphere. However, large meteorites have hit the earth's surface in the distant past. This is indicated by large craters, which have been found in different parts of the earth. Also, it is possible that an asteroid may have fallen on the earth in prehistoric times - the last one some 65 million years ago during the Cretaceous period.

Scientists Drill into Ancient, Underwater Coral Reef A voyage to the outer edges of Australia's Great Barrier Reef has brought back pieces of an ancient, fossilized ancestor to the vast, living ecosystem. This fossilized coral reef was alive about 20,000 years ago, during the height of the last glacial period, a time when Earth was around 9 degrees Fahrenheit (5 degrees Celsius) cooler than it is now, and the city of Chicago was buried beneath an ice sheet almost 2 miles (3 kilometers) thick. By studying this ancient coral, scientists are hoping to put together the most accurate picture yet of how sea levels have changed over thousands of years, data that can help inform projections of how sea levels may change in the future. Getting to the ancient coral, a sort of great-great-grandfather to the Great Barrier Reef, posed a challenge; it lies on and below the ocean floor. [See images from the expedition.]
