The sabertooth cat (Smilodon fatalis), one of the most iconic extinct mammal species, was likely to be a social animal, living and hunting like lions today, according to new scientific research. The species is famous for its extremely long canine teeth, which reached up to seven inches in length and extended below the lower jaw

MARYLAND, US; December 27, 2008.- Instead of relying on the bones and teeth of the sabertooths to make their findings, scientists from UCLA and the Zoological Society of London concluded that the sabertooth cat was social by using a novel technique: They compared numbers of present-day carnivores competing for kills in Africa with those of mainly extinct species found in a North American fossil deposit.

At Paper Fiber Americas, a wastepaper exporter in Portland, Ore., tons of cans, beer boxes, newsprint and plastic jugs form a huge mountain of recycling. John Dryden, who runs the exporting operation, says when he looks at the large pile of trash, he normally sees money

WASHINGTON, D.C., US; December 26, 2008.- But recently, Dryden’s business has been transformed by countless consumers who are opting to buy less. Those small, individual choices to hold off on certain purchases put fewer boxes under their Christmas trees and mean there’s less cardboard and paper to recycle.

Plants, genetically modified to ease the breaking down of their woody material, could be the key to a cheaper and greener way of making ethanol, according to researchers who add that the approach could also help turn agricultural waste into food for livestock

MARYLAND, US; December 26, 2008.- Lignin, a major component of woody plant material,, is woven in with cellulose and provides plants with the strength to withstand strong gusts of wind and microbial attack. However, this protective barrier or “plastic wall” also makes it harder to gain access to the cellulose.

Increased emissions of carbon dioxide affect more than the atmosphere. Much of the CO2 is absorbed by the oceans, causing them to become more acidic

WASHINGTON, US; December 26, 2008.- Recent research has looked at the impact of the acidification on corals and other small calcifying organisms. But increasing CO2, coupled with gradual warming of the oceans, may have other effects, and may affect bigger creatures, because there will be less oxygen at the surface and deep oxygen-poor zones will expand vertically.

In a study that challenges current ideas about the insect brain, researchers have found that honey bees on cocaine tend to exaggerate

MARYLAND, US; December 26, 2008.- Normally, foraging honey bees alert their comrades to potential food sources only when they’ve found high quality nectar or pollen, and only when the hive is in need. They do this by performing a dance, called a “round” or “waggle” dance, on a specialized “dance floor” in the hive. The dance gives specific instructions that help the other bees find the food.
