Feathered Predator?

The largest feathered animal, living or extinct, unearth in China is a dinosaur.

The dinosaur is a smaller and furrier cousin of the Tyrannosaurs Rex family reported Discovery News. They are the largest feathered dinosaur found and are said to be 40 times the weight of the second larges feathered dinosaur.

There have been three specimens found in good preserved condition with their feathers still around them reported The New York Times.The specimens are roughly 125-million-years-old.

Scientist think that these dinosaurs had more fuzzy feathers like baby birds instead of having actual plums of feathers. They also think that the feathers were used for insulation and show reported Discovery News.

According to The New York Times, the discovery of these specimens give insight as to the evolution of feathers.

They topic as to what specifically the feathers were used for other then insulation is still being debated along with the idea of other dinosaurs also having some feathers reported The New York Times.

This new species is called Yutyrannus huali, which translated means "beautiful featherd tryant" reported The New York Times.

China Holds the Key

China holds over 97 percent of the earth's rare earth mineral's that are used in things from car batteries to advanced energy technologies.

There are 17 elements that fall in to the rare earth minerals, but in reality they aren't rare, but quiet common. They are just found in very small amounts, which aren't cost efficient enough to mine reported National Geographic.

According to ABC News, the United States, Japan and the European Union have filed a complaint against China for the use to minerals. They feel that China needs to loosen its grip on their exports so that the price for these minerals will go down.

Many scientist are trying to find substitutes for these minerals to possible eliminate the high demand on them, reported National Geographic.

According to National Geographic, the complaint is being moved forward slowly within the World Trade Organization, and scientists from rare-mineral countries are hoping to find a substitute soon.

Poachers have killed over half of the elephants living in Bouba N'Djida National Park in Cameroon, Africa.

According to Scientific America, the National Park in the small African nation held about 450 elephants, which is roughly 80 precent of central Africa's savanna elephants.

It is believe that over 150 elephants have been killed since January reported The New York Times.

Richard Carroll, the vice president of the World's Wildlife Fund (WWF) U.S. Africa Programs, told Scientific America that the poachers, who mainly want the ivory tusks of the elephants, have to travel up to 1,000 miles through Chad and the Central African Republic to reach Cameroon's national park.

What is fueling this recent mass killing of elephants in Cameroon is the high demand for ivory in China, even though ivory trafficking has been banned since 1988 reported Scientific America.

Cameroon has sent in military forces to try and stop the poachers, but it has had little to no effect except for getting on soldier killed reported The New York Times.

According to The New York TImes, Natasha Kofoworola Quist, the head of WWF's Central Africa operations, said "This is not just a wildlife issue, and it is not just a Cameroon issue. This is a global issue."

Leonardo da Vinci's lost Mural Finally Found?

Researchers believe that they have found da Vinci's lost mural,"The Battle of Anghiari", hidden behind a wall in Florence's city hall.

In 1502 the Italian statesman Piero Soderini requested Leanardo da Vinci to paint a piece dedicated to the Italian Knights defeating the Milanese forces in 1440 on a wall of the capital reported National Geographic. Da Vinci was known for not being fond of war and, is said to have eventually given up the mural after a failed attempt at a new technique reported MSNBC.

According to National Geographic, a painter by the name of Giorgio Vasari was hired to redo the city hall in the 1550's and it is said that he could not bring himself to paint over da Vinic's mural. Vasari instead build a fake wall in front of da Vinic's mural.

Maurizio Seracini, a National Geographic Society member and an art diagnostician at the University of California, San Diego, was the first to suspect that the painting was behind Vasari's, when he found the saying "seek and you shall find" inscribed on a flag within his painting reported BBC and National Geographic.

In an effort to avoid harming the original Vasari painting that is located in front of the thought-to-be da Vinic mural, researchers were allowed to drill tiny holes through cracks or recently restored pieces of the painting reported National Geographic. They used a micro endoscopic probes and other high tech devises to examine behind the painting and discovered black pigment and red flakes of what they believe is paint reported MSNBC.

This data is still inconclusive without further research into the suspected da Vinic mural. Research has been halted for now due to outcry by the public and government officials reported National Geographic.
