Tropical Cooling Linked To Late Ordovician Mass Extinction

Tropical Cooling Linked To Late Ordovician Mass Extinction

Apr 23 2012 | comment(s)

The second-largest mass extinction in Earth's history, the so-called Late Ordovician mass extinction, coincided with a short but intense ice age during which enormous glaciers grew and sea levels dropped.

The Late Ordovician mass extinction occurred about 450 million years ago and was related to climate change, that has been known, but exactly how the climate change produced the extinction has not. A team led by scientists at the California Institute of Technology (Caltech) has created a framework for weighing the factors that might have led to mass extinction and has used that framework to determine that the majority of extinctions were caused by habitat loss due to falling sea levels and cooling of the tropical oceans.
Solar-Grade Silicon May Get A Lot Cheaper And Generate A Lot Less CO2 From Solar Panel Manufacturing

Solar-Grade Silicon May Get A Lot Cheaper And Generate A Lot Less CO2 From Solar Panel Manufacturing

In a development that would be bad for the U.S. Department of Energy but good for solar power worldwide, a new process developed by scientists at the University of Cambridge has the potential to drive down the cost of manufacturing solar-grade silicon and boost use of photovoltaic devices.
Dark Matter Theory Takes A Hit

Dark Matter Theory Takes A Hit

Apr 18 2012 | comment(s)

Widely accepted theories of dark matter,  a mysterious invisible substance that can only be detected indirectly by the gravitational force it exerts, expect the solar neighborhood to be filled with the stuff - but it isn't, at least as far as can be detected.
What Took So Long? 200 Activists Launch Themselves Off Mt. Kilimanjaro

What Took So Long? 200 Activists Launch Themselves Off Mt. Kilimanjaro

Apr 18 2012 | comment(s)

Don't get too excited but 200 activists are going to jump off Mt. Kilimanjaro in Tanzania.

These aren't the usual pesky environmentalists, these are hang-gliding global activists, which really sounds like just an excuse to go hang-gliding but get permits to do it in cool places but it's still going to raise money for a worthy cause.

Trading Planets - How Space Is Like Baseball

Trading Planets - How Space Is Like Baseball

Billions of stars in our galaxy have acquired released planets that once roamed interstellar space. Those free agent worlds left the star systems in which they formed, and found a new home with a different sun.

If it sounds a lot like baseball, that's because it is, said Hagai Perets of the Harvard-Smithsonian Center for Astrophysics, making the most incongruent cosmological metaphor of April 17th, 2012.
Poison Becomes Food: Worm Lives On Carbon Monoxide And Sewer Gas

Poison Becomes Food: Worm Lives On Carbon Monoxide And Sewer Gas

Apr 17 2012 | comment(s)

A small marine worm, Olavius algarvensis, is faced with a scarce food supply in the sandy sediments it lives in off the coast of Elba, so it must deal with a highly poisonous menu: it lives on carbon monoxide and hydrogen sulfide.

O. algarvensis can thrive on these poisons thanks to millions of symbiotic bacteria that live under its skin. The bacteria use the energy from carbon monoxide and hydrogen sulphide to produce food for the worm, just like plants do by fixing carbon dioxide into carbohydrates - but instead of using light energy from the sun, the symbionts use the energy from chemical compounds like carbon monoxide.
