4 . Africa’s fight against poaching(偷猎) is often described as a war. Illegal killing is on the rise, fueled by the growing demand for ivory and rhino horn. Experts say that more than 35,000 African elephants are killed every year. And rhino poaching is thought to have reached its highest levels.

Some African rangers(巡逻队员) no longer just walk around to prevent poaching. South Africa is using drones(无线电遥控的无人飞机) to watch over its wildlife in national parks. Kenya plans to do the same. The fight against poaching is a modern war, and it is becoming increasingly high-tech.

Mike Chambers runs Bathawk Recon, the company that made the drones. Drones are a technological tool that can cover large areas, greatly reduce poaching and give rangers help.

Mike Chambers says that Tanzania’s rangers do not have the resources even to keep up with poachers. “With a quarter of a million square kilometers of protected area, it’s impossible with the budget that Tanzania has to cover that area, especially at the moment, where the resources for poachers are rising because of the international demands.”

In neighboring Kenya, the wildlife service is focusing on genetics to against poachers. Last month the service opened a lab where bush meat can be identified.

Philip Muruthi, Chief Scientist for the African Wildlife Foundation, says that along with ivory poaching, illegal bush meat hunting is also reducing Kenya’s wildlife population. Until now charging those who hunt illegally has been difficult. Poachers often say giraffe or zebra meat is beef, and so proving can be difficult.

Muruthi says the new lab can be able to tell the kind of animal the meat comes from. The lab also will be able to provide a genetic database of Kenya’s endangered animals. The information can help charge poachers.

5 . Experts using a high-tech laser scanner (激光扫描仪) have discovered thousands of ancient Maya buildings hidden under the thick forests of northern Guatemala, officials said Thursday. Some 60, 000 buildings were found over the past two years in a scan of an area in the northern department of El Peten between Mexico and Belize, said Marcello Canuto, one of the projects’ lead researchers.

These findings are a “breakthrough in Maya archeology(考古),” Canuto said.

The new discoveries in this Central American country include city centers with sidewalks, homes, wide steps, farming facilities and so on, said Canuto, an archaeologist at Tulane University in the United States.

Among the finds was a 30-meter high pyramid (金字塔) that had been earlier recognized as a natural hill in Tikal. Also discovered in Tikal: a series of holes and a 14 kilometer-long wall.

The Maya development reached its height in what is present-day southern Mexico, Guatemala, and parts of Belize, El Salvador and Honduras between 250 and 950 CE. Researchers now believe that the Maya had a population of 10 million, which is “much higher” than previous judgment, Canuto said.

The project depended on a remote (远程的) sensing method known as LiDAR (Light Detection and Ranging). Aircraft with a LiDAR scanner produced 3D maps of the surface by using light in the form of laser linked to a GPS system.

The technology helped researchers discover sites much faster than using traditional archeological methods. “Now it is no longer necessary to cut through the jungle to see what’s under it,” said Canuto.

Details of the research will appear in a documentary to air on February 11 on the National Geographic TV channel, said Minister of Culture and Sports Jose Luis Chea.

6 . Yangzhou paper cutting, with a history of 2,000 years, can be dated back to the Sui Dynasty, making Yangzhou one of the places where paper cutting first became popular.

In the Sui Dynasty, the people of Yangzhou would cut colourful paper or silk and satin (缎子) to celebrate festivals. It is said that Emperor Yang came to Yangzhou three times. In winter, the flowers and trees in the garden became dry and weak. The emperor ordered the gril servants to cut fine silk and satin into flowers and leaves and use them to decorate the trees and lakes. Since then, “colorful cutting” has become a popular art in Yangzhou.

In the Tang Dynasty, the paper cutting industry was highly developed and a large amount of high-quality paper was made as presents to the Court (宫廷).

In the Qing Dynasty, because of the economic development, the people of Yangzhou became interested in wearing fine clothing, especially embroidered (刺绣的) clothing. The embroidered designs were based on paper-cuts, the most well-know of them was from Bao Jun, a paper cutting master. He won a high reputation (名声) as Magic Scissors for his wonderful cutting skills.

After the People’s Republic of China was started, the Chinese government accepted the importance of paper cutting like many other arts and skills. In 2007, China Paper-cuts Museum opened to the public in the back garden of the Wang’s Residence (住所), Yangzhou, greatly helping the development of Yangzhou paper cutting.

7 . On the 100th anniversary of the Communist Party of China (CPC), red tourism has gained popularity among tourists who flood in to visit historic sites with a modern revolutionary heritage.

Jinggangshan

This is one of the most crucial and splendid chapters of history of establishing Red China as well as a unique and wonderful ecosystem, which is covered with rich forest, rugged peaks and several memorials to the Red Army. The best time to visit is between April and October, with the most temperature timing April and May when the large azaleas (杜鹃花) bloom.

Open: 8:00-17:00 (Feb. 16-Nov. 15). 8:00-16:30 (Nov. 16-Feb. 15)

Xibaipo

It is an old revolutionary base where the leadership of the Communist Party of China was stationed, drawing up the blueprint for a new country. A memorial hall was built to honor the memory of this site. The lake and the hill here add brilliance and beauty to each other and form pleasant scenery.

9 . In the Brazilian Amazon, a species of monkey called the pied tamarin（绢毛猴）is fighting for survival, threatened by habitat loss and urban development. But the severely endangered animals faces another enemy： the red - handed tamarin, a monkey that lives in the same region.

They compete for the same resources, and the red - handed tamarinds habitat range is expanding into that of the pied tamarins'. Their conflicts sometimes end in violent argument.

But in a recent study, scientists have discovered that the red - handed tamarin is changing its vocal calls to better communicate with the pied tamarin. Tainara Sobroza, an ecology Ph. D. student who worked on the study, says these calls are used to warn other species that they are invading their territory, or coming too close to a crucial survival resource. "When this happens? the two species usually engage in vocal battles," she says, which sometimes prevent the violent physical battles between the two species.

Researchers compared the change in calls to speaking with an accent, "They might need to say 'tomahto' instead of 'tomato — that's the kind of delicate difference in the accent, so that they can really understand each other," Jacob Dunn, a professor of evolutionary biology who worked on the study, told The Guardian.

When analyzing the vocal call of both species, the scientists discovered that the red - handed tamarins^, new call has a narrower bandwidth （带宽）and an increased amplitude （振幅）,making the sound clearer and the duration of the call longer. The result is a call that travels better through the thick forest.

The hope is that this work will help conservationists to better design reserves and other survival chances for the pied tamarins. And because these two species are so rarely seen physically in the same space, listening is one way to do that work. "We don't have to actually see,"   Sabroza says. "We can hear the ecological interaction. "
