Slash and Sprawl: U.S. Eastern Forests Resume Decline
Posted by Scientific American - Energy & Sustainability on 13 April, 2010
Trees once covered almost the entire eastern seaboard of the U.S. Vast forests supported a rich ecosystem, including flocks of the extinct passenger pigeon big enough to blot out the sun. But by the 1920s at least half of this forest was gone–a victim of tree-clearing for farming, forestry or fossil-fuel extraction. [More]
Hey, Is That Me over There?
Posted by Scientific American - Energy & Sustainability on 13 April, 2010
If there is anything about your “self” of which you can be sure, it is that it is anchored in your own body and yours alone. The person you experience as “you” is here and now and nowhere else.
But even this axiomatic foundation of your existence can be called into question under certain circumstances. Your sense of inhabiting your body, it turns out, is just as tenuous an internal construct as any of your other perceptions–and just as vulnerable to illusion and distortion. Even your sense of “owning” your own arm is not fundamentally different–in evolutionary and neurological terms–from owning your car (if you are Californian) or your shotgun (if you are Sarah Palin).
More Food from Fungi?
Posted by Scientific American - Energy & Sustainability on 13 April, 2010
To feed an exploding global population, scientists have called for a doubling of food production over the next 40 years. Genetic manipulation might seem the best way to quickly boost characteristics essential to plant growth and crop yields. New findings from different laboratories, however, suggest that fungi, bacteria and viruses could be an exciting alternative to increase agricultural productivity.
Scientists have long known that microbes can work symbiotically with plants. For instance, mycorrhizal fungi, which are associated with 90 percent of land plants, extend from roots to bring in moisture and minerals in exchange for plant carbohydrates. But microbes have recently been found among plant cells themselves and seem to confer benefits, such as more efficient photosynthesis and increased ability to fix nitrogen from the air. In fact, Mary E. Lucero, a biologist at the U.S. Department of Agriculture’s Jornada Experimental Range in Las Cruces, N.M., believes that plants actively recruit these microbes rather than simply being passive hosts for them.
Diminutive, but not disappeared: Rare dwarf lemur rediscovered 100 years after last sighting
Posted by Scientific American - Energy & Sustainability on 13 April, 2010
Last week, we told you about some of the bad news in Madagascar, a nation whose political troubles have created a thriving illegal economy for rare wildlife species. But here’s some good news from that same country: a species of lemur not seen in 100 years has been rediscovered . [More]
