Speeding Up Mineral Reactions To Fight Global Warming
The more familiar method of carbon dioxide sequestration involves capturing and pumping the gas into underground reservoirs where geological traps that have sealed natural gas for millions of years will serve to lock captured CO2 for eons as well. Nature has published a paper by Jürg M. Matter and Peter B. Kelemen that proposes another method of CO2 sequestration, locking CO2 as carbonate minerals by reaction with a host rock. Anthropogenic greenhouse-gas emissions continue to increase rapidly despite efforts aimed at curbing the release of such gases. One potentially long-term s

Meteorite Impact Ended Banded Iron Formation Deposition
From the November issue of Geology: Extraterrestrial demise of banded iron formations 1.85 billion years ago; John F. Slack and William F. Cannon In the Lake Superior region of North America, deposition of most banded iron formations (BIFs) ended abruptly 1.85 Ga ago, coincident with the oceanic impact of the giant Sudbury extraterrestrial bolide. We propose a new model in which this impact produced global mixing of shallow oxic and deep anoxic waters of the Paleoproterozoic ocean, creating a suboxic redox state for deep seawater. This suboxic state, characterized by only small concentration

Arctic: Carbon Sink Or Source?
The USGS has quite an informative press release via Geology.com and a graphic depicting how warming will affect the physical structure of the soil and permafrost in the Arctic region resulting in the release of carbon dioxide and methane.

You'll Understand Homeopathy If You Understand Einstein
....Homeopathy - can it get more stupid than this...? Warning: Advanced degree in physics and chemistry required to follow this discussion: Now you know why those white pills pack so much punch! They are literally powder kegs of energy.

Teaching Human Evolution In Pakistan Can Be Dangerous
Kenneth Chang of New York Times has written an interesting summary on the teaching and acceptance of evolution across Muslim countries and among Muslim immigrants in many western nations. Atomic physicist Pervez. A Hoodbhoy went through a dramatic moment while lecturing at a university in Pakistan: Pervez A. Hoodbhoy, a prominent atomic physicist at Quaid-e-Azam University in Pakistan, said that when he gave lectures covering the sweep of cosmological history from the Big Bang to the evolution of life on Earth, the audience listened without objection to
