j7uy5 | November 26, 2009Environmental regulations have greatly reduced the amount of sulfur in
gasoline. This has created many benefits. But did you ever
wonder what happens to all that sulfur? Perhaps not, if it was
never clear to you why you should care.
The reason you should care is this: Sulfur is present in coal and
in most liquid fuels. When it is burned, it oxidized, much as the
carbon is oxidized. Carbon becomes carbon dioxide; sulfur becomes
sulfur dioxide. When sulfur dioxide enters the atmosphere, it
becomes a strong acid: sulfuric acid, which is battery acid. This
is one factor that contributes…
razib | November 20, 2009Pleistocene Megafaunal Collapse, Novel Plant Communities, and Enhanced Fire Regimes in North America:
Although the North American megafaunal extinctions and the formation of novel plant communities are well-known features of the last deglaciation, the causal relationships between these phenomena are unclear. Using the dung fungus Sporormiella and other paleoecological proxies from Appleman Lake, Indiana, and several New York sites, we established that the megafaunal decline closely preceded enhanced fire regimes and the development of plant communities that have no modern analogs. The loss of…
mikethemadbiologist | November 20, 2009...and how Levitt and Dubner fail to see that the Manure problem was not 'solved', only turned into a new problem that will also require wrenching change. First, the Great Manure Crisis of the late nineteenth century:
The standard horsecar, which seated twenty, was drawn by a pair of roans and ran sixteen hours a day. Each horse could work only a four-hour shift, so operating a single car required at least eight animals. Additional horses were needed if the route ran up a grade, or if the weather was hot. Horses were also employed to transport goods; as the amount of freight arriving at the…
aardvarchaeology | November 16, 2009Dan Simmons published a wonderful, galaxy-spanning, mind-blowing sf novel in 1989: Hyperion. Then he followed it up with three more novels of which I have read two. They're OK, but not as good as the first book.
Science fiction is of course stories where fabulous things happen and are explained by science and technology rather than magic. There are two ways to do this: either you offer an explanation that is actually in line with what we know now and sort of makes sense, or you use technobabble to cover the fact that you, the writer, do not actually have any idea of how for instance space…

When you think about it, it seems pretty obvious (rising to the level of "duh!") that if one placed a wind turbine underwater it could be more efficient and, unlike wind power, ocean currents are far more predictable (of course, like most good ideas, it's obvious after someone else thought it...). A spinoff of the Saab corporation is developing such a system:
A completely new concept of underwater wave energy using a simple 7 ton kite turbine design has been developed by Minesto; which is a spinoff from the Swedish military and aircraft design firm Saab. The Deep Green…

American Scientist Pizza Lunch convenes again at noon, Tuesday, Nov. 24 at Sigma Xi's headquarters in Research Triangle Park.
The speaker will be Alex Huang, a professor of electrical and computer engineering at NC State University. Prof. Huang is directly engaged with trying to reduce this country's dependence on carbon-emitting fossil fuels. He directs a national research center working on a redesign of the nation's power grid to better integrate alternative energy sources and new storage methods.
American Scientist Pizza Lunch is free and open to science…
pharyngula | November 12, 2009About 2½ years ago, I highlighted the environmental threats to the Australian lungfish, in particular the planned construction of a dam that would destroy their habitat.
To my surprise, Australian environmentalists won this battle!
The proposed $1.8 billion Traveston Dam in Queensland has been quashed to protect endangered species, including Mary River turtle and cod, after a landmark decision by the Environment Minister, Peter Garrett.
In explaining his decision yesterday Mr Garrett said the dam would have ''serious and irreversible effects'' on threatened species - which also include the…
gregladen | November 2, 2009The Go Green Expo is, according to its organizers, the nation's leading eco-focused, interactive and educational showcase. It will debut at the Minneapolis Convention Center this coming weekend, including talks, presentations, and exhibits from a variety of sources including "green businesses". The idea is to promote energy-efficient and environmentally-friendly products and services. The Expo will include interactive seminars featuring leaders in the green industry, local politics, and community organizations.
I'm going to be officially blogging it, so if you are going send me an email…

You know that trees store carbon, but what does that really mean? How much carbon does the tree outside your window store, and how does that compare to the carbon we emit when we travel or power our homes?
How many trees are in your yard? I don;t have a yard (I have a fire escape), but my neighborhood is being revitalized by BYC's "Million Trees" project, so roughly by the time that I leave for Germany, the city will be planting trees on the street in…
