Earth Changes
An increasing number of companies developing new products through biological discovery or "bioprospecting" are trying to file patents on Antarctic organisms or molecules for items from cosmetics to medicines, putting new strains on the treaty.
"Biology is going through a revolution ... it's a tricky situation," Jose Retamales, head of the Chilean Antarctic Institute, said of the lack of clear rules for prospecting for animals and plants on the continent.
Researchers have found that the larvae and pupae of Maculinea rebeli - a parasitic butterfly native to western Europe, though threatened with extinction - impersonate red ants so faithfully that worker ants worship them as if they were queens, caring for the developing caterpillar even at the expense of their own lives.
Super Strong Stratospheric Warming Event to Bring More Cold and Snow as Grand Finale to 08/09 Winter
The problem is this: Parts of the nation's longest river are losing elevation. The so-called "degradation" process is not affecting the amount of water in the channel, but the water is physically lower on the Earth because the river bottom is washing away.
The water depth is not changing, and the situation is nearly imperceptible from shore. But for engineers, it's a costly headache.
"Part of the whole problem is it's not visible," said John Grothaus, chief of planning for the Army Corps of Engineers in Kansas City, where the river bed has dropped by about 12 feet over the last 50 years.
"It's not in the public eye. You can't see it on the river".

Achaea catocaloides, the caterpillar that began devouring Liberia's trees and crops in January 2009, turns into a moth that can lay 500 to 1,000 eggs if not killed beforehand. Experts fear the cycle could begin anew if the caterpillars are not contained.
In early January, when the long, black caterpillars reached the creeks that serve as the main water sources for the town of Belefanai in north-central Liberia, the creatures' feces instantly turned streams dark and undrinkable.
Moving through the forest canopy on webs, devouring the leaves as they went, the caterpillars advanced like nothing the townspeople had ever seen.
The drought gripping parts of central and northern China has sent Zhengzhou wheat futures prices CWSK9 up 5 percent this week but physical prices W-EXWZGZ-GEN have not moved, with most investors confident the country's reserves and last year's big harvest can offset any fall in wheat production this spring.
But the drought could hurt the incomes of farmers in Henan, Anhui and other populous provinces when many have lost factory and construction jobs after China's growth faltered in late 2008.

Black wolves dominate packs in the forests of North America, while white wolves are more numerous in the treeless tundra.
"Although it happened by accident, black wolves are the first example of wolves being genetically-engineered by people," said Marco Musiani, an internationally-recognized expert on wolves and a professor in the U of C's Faculty of Environmental Design. "Domestication of dogs has led to dark-colored coats in wolves, which has proven to be a valuable trait for wolf populations as their arctic habitat shrinks," Musiani said. "It also shows that human activities can help enrich the genetic diversity of wild animal populations, which is a very unexpected finding."
Buffalo State College hosts the national teach-in on Global Warming Situations today - a day the local temperature bottomed out at minus 6 degrees.
No evidence of global warming here, at least not this morning, when unofficial reports to the National Weather Service listed temperatures as low as 9 degrees below zero elsewhere in Erie County.
"We didn't have temperatures forecast to be quite that cold," weather service meteorologist David Zaff said this morning. "When you have snowpack on the ground and clear skies, temperatures can plummet. It's called radiational cooling."
That cooling phenomenon, under mockingly clear skies, posed a hardship for some morning commuters and some finger-numbing discomfort for others.
The evidence takes the form of chemical markers that are highly distinctive of sponges when they die and their bodies break down in rock-forming sediments.
The discovery in Oman pushes back the earliest accepted date for animal life on Earth by tens of millions of years.
Scientists tell Nature magazine that the creatures' existence will help them understand better what the planet looked like all that time ago.
The birds were found on January 29 and 31 on a beach on Lantau island and preliminary tests showed they had tested positive for H5 avian influenza.
Further tests confirmed it was the H5N1 strain of the virus, a spokesman for the Agriculture, Fisheries and Conservation Department said in a statement.
