Mother Of All Humans Lived 200,000 Years AgoHouston TX (SPX) Aug 24, 2010 The most robust statistical examination to date of our species' genetic links to "mitochondrial Eve" - the maternal ancestor of all living humans - confirms that she lived about 200,000 years ago. The Rice University study was based on a side-by-side comparison of 10 human genetic models that each aim to determine when Eve lived using a very different set of assumptions about the way humans migrated, expanded and spread across Earth. The research is available online in the journal Theoretica ... read more |

The shelly fossils, found beneath a 635 million-year-old glacial deposit in South Australia, rep ... more  
Houston TX (SPX) Aug 24, 2010A new study by geochemists at Rice University finds that damming and other human activity has completely obscured the natural carbon dioxide cycle in Texas' longest river, the Brazos. "The natural factors that influence carbon dioxide cycling in the Brazos are fairly obvious, and we expected the radiocarbon signature of the river to reflect those influences," said study co-author Caroline ... more

Pakistan president warns flood recovery could take yearsKarachi (AFP) Aug 24, 2010 Pakistan's President Asif Ali Zardari warned the country could take three years or more to recover from near-month long floods as authorities battled to protect cities from rising waters. The floods have killed 1,500 people and affected up to 20 million nationwide in the country's worst natural disaster, with the threat of disease ever present in the camps sheltering survivors. "Your guess is as good as mine, but three years is a minimum," Zardari told reporters when asked how long it would take ... read more |
