Image via Wikipedia This week I've been thinking about and playing with ideas for what my new world should be like. I started off with the realism and utility of a Pangaea type world. This has lots of pros: there's plenty of info available, it's a big old landmass to roam across, it's believable, without the separation of the sea even low tech cultures are capable of long range exploration and contact....

Can storms prevent nasty earthquakes? That's the suggestion of study showing that typhoons can trigger benign, "slow" quakes that ease the stress between tectonic plates. Beneath Taiwan, a tectonic plate is diving under its neighbouring plate at one of the world's fastest rates. "You can almost watch them," says study co-author Alan Linde of the Carnegie Institution in Washington...

Forty years ago this month the lunar surface reverberated with life for the first time. Forty years from now will Mars, too, come alive? President Barack Obama has affirmed the broad goals for human spaceflight that his predecessor put forward in 2004: retire the shuttle in 2010, develop a replacement line of rockets (named Ares), return to the moon by 2020, and go to Mars, perhaps in the mid-2030s...

A conundrum has long vexed geoscientists: How to reconcile convection of the Earth's mantle with observations of ancient noble gases in volcanic rocks. Solving the problem requires that the recycling of tectonic plates into the Earth's lower mantle is balanced by hot, buoyant mantle plumes that rise with little mixing to the Earth's surface, producing volcanic island chains like Hawaii.

"Scientists long have focused on how climate and vegetation allowed human ancestors to evolve in Africa. Now, University of Utah geologists are calling renewed attention to the idea that ground movements formed mountains and valleys, creating environments that favored the emergence of humanity. "Tectonics [movement of Earth's crust] was ultimately responsible for the evolution of humankind,"...

Rain Water Harvesting in Mumbai, India: Application of GIS Prakash M Apte Abstract: Surface water is inadequate to meet demands of our urban centres. While infiltration of rain water into the sub-soil has decreased, pressure of population growth and industrialization has accelerated the rate of drawing underground water in excess of the rate at which the water table gets recharged by natural means....
