Fertilizer runoff and fossil-fuel use lead to massive areas in the ocean with scant or no oxygen, killing large swaths of sea life and causing hundreds of millions of dollars in damage
More bad news for the world’s oceans: Dead zones—areas of bottom waters too oxygen depleted to support most ocean life—are spreading, dotting nearly the [...]

Q. WHEN YOU GAVE A RECENT SPEECH AT COLUMBIA UNIVERSITY ADVOCATING GENETICALLY MODIFIED FOODS, SOMEONE SITTING NEAR ME SAID, “OH GREAT, OUR STATE DEPARTMENT IS PUSHING G.M. FOOD. SHE’S THE AMBASSADOR FROM MONSANTO.” WHAT’S YOUR RESPONSE?
A. How do I answer him? My answer is: There’s almost no food that isn’t genetically modified. Genetic modification is [...]
Drilling for oil in algae

There may be a revolution blowing our way: The Israeli company Seambiotic has found a way to produce biofuel by channeling smokestack carbon dioxide emissions through pools of algae that clean it. The growing algae thrives on the added nutrients, and become a useful biofuel.
For the last two years, the company has done something [...]
Installing a Reverse-Osmosis Water Filter

Reverse osmosis (RO) is generally recognized as the best system for purifying water while retaining good taste. The EPA recommends reverse osmosis filters for microbiologically safe water. Yet, an RO system alone will still allow certain waterborne germs to pass through. To knock out these types of contaminates, most RO systems incorporate some additional type [...]

When you flush in Santa Ana, the waste makes its way to the sewage-treatment plant nearby in Fountain Valley, then sluices not to the ocean but to a plant that superfilters the liquid until it is cleaner than rainwater. The “new” water is then pumped 13 miles north and discharged into a small lake, where [...]
Found: The hottest water on Earth – New Scientist Environment
Posted in oceans, water facts on August 4, 2008 | Leave a Comment »
Even Jules Verne did not foresee this one. Deep down at the very bottom of the Atlantic Ocean, geochemist Andrea Koschinsky has found something truly extraordinary: “It’s water,” she says, “but not as we know it.”
At over 3 kilometres beneath the surface, sitting atop what could be a huge bubble of magma, it’s the hottest [...]

‘Major discovery’ from MIT primed to unleash solar revolution – MIT News Office
Posted in energy efficiency on August 3, 2008 | Leave a Comment »
In a revolutionary leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn’t shine.
Until now, solar power has been a daytime-only energy source, because storing extra solar energy for later [...]
