1 . Brazilian scientists think they might have found a way to undo the damage caused by the cutting down of trees and turn farmland back into forest. The secret lies in ancient local knowledge of soil.
Amazonian Dark Earth (ADE) is a thick, black soil found deep in the Amazon rainforest, and it could help restore forests around the world. ADE is a kind of compost (soil made from dead plants and animals). Various kinds of compost are sold in gardening centers around the world, but ADE is unique. It was created by indigenous people from the Amazon between 2,000 and 2,500 years ago. The Amazonian people, today known as Amerindians, created ADE using charcoal from fires, animal bones, food waste and poo. It contains microbes (微生物) that help to turn chemicals in the soil into useful nutrients that feed plants and trees.
Vast areas of the Amazon have been cut down, mostly to make way for grassland for raising cattle. Scientists are looking for a way to turn grassland back into rainforest and revive forest ecosystems. These support thousands of animal and plant species, many of which are unique to the area. Forests also absorb lots of carbon dioxide.
To see if the Amazon’s special soil could help, the scientists grew grasses and trees in ADE, regular earth and a mixture of both. Trees grown in ADE were up to six times taller than those in regular soil. ADE takes hundreds of years to create, so the scientists can’t simply make more. Team member, Dr Siu Mui Tsai, said that instead they want to try and “copy its characteristics”, especially its helpful microbes, and see if it could help to restore natural habitats.

2 . Longing for the most amazing places on the planet? You can do no wrong with these lakes across the globe.
Five Flower Lake
Set in the striking karst landscape of the Jiuzhaigou Valley in Sichuan province, China, Five Flower Lake is extraordinarily clear, with visibility to a depth of 40 metres. Five Flower is one of a series of blue-, green-and sky-colored lakes blocked by rock falls, but it differs from the others as its waters change color, looking sometimes yellow, sometimes green, but usually diamond blue. In winter, Five Flower never freezes; in summer, it never dries up. Local wildlife living in the surrounding mountain forests include the rare giant panda and the golden snub-nose monkey.
Crater Lake
The deep-blue waters of Crater Lake in Oregon, US, fill the outlet of an ancient volcano that collapsed 7,700 years ago. Its strangest occupant is the “Old Man of the Lake”, a nine-metre-tall tree stump(树桩), which has stood upright in the water for more than a century. No rivers or streams enter the lake. Water loss in summer is compensated by winter snow and rain, the entire body of water being replaced every 250 years.
Lake Ohrid
Ancient Lake Ohrid has been around for about five million years and crosses the mountainous border between Macedonia and Albania. It has unique plants and wildlife, including the Ohrid “plashica”, a fish native to the lake, whose scales(鳞片) are used to make Ohrid pearls.
Lake Maggiore
Surrounded on three sides by the Lipontine Alps and touching the plain of Lombardy to the south, Lake Maggiore is Italy’s longest lake. Considered part of the country’s lake district, it is shared with Switzerland. Characterized by a Mediterranean-style climate, temperatures here are mild all year. This has given rise to some of northern Italy’s most wonderful gardens, which appear to float like flower-decked boats on the water.

5 . The Most Breathtaking Theaters in the World
Shakespeare's Globe Theater(London, UK)
The original Globe Theater was built by Shakespeare's company in 1599, but was destroyed by fire in 1613. A replica was built in 1997 just meters from the original site. The new 857-seat structure has several modern features. It has the first and only straw roof permitted in London since the great fire of 1666.

Margravial Opera House(Bayreuth, Germany)
Built in 1745, the UNESCO-listed Mareravial Opera House is regarded as the finest baroque theater in Europe. The stage has a depth of 27 meters and was the largest in Europe until 1871. Much of the original materials remain, along with original structures, such as the twin staircases.

Teatro Amazonas(Manaus, Brazil)
There can't be many theaters located in the middle of the Amazon rainforest, and the Teatro Amazonas is certainly the most breathtaking.

The NCPA includes value in both ancient traditional Chinese architecture and modern architecture. It was specially designed to improve the red walls of ancient buildings and the Great Hall of the People in order to fit in with the surroundings.

A tour along the Great Wall will enable you feel the wisdom of the ancient Chinese and the thousands of years changes.
7 . Got big plans for Friday night? That’s OK, we don’t either.
Guess we’ll all have to make do by watching the celestial (天空的)show that will take place that night.
First, there will be a full moon. That’s always fun, but this one will be a little more special. It’s known as a “snow moon.” The name comes from the fact that the heaviest snows usually fall during February, according to the Old Farmer’s Almanac.
But if that’s not special enough, there’s also an eclipse (月食)that night. It’ll be a penumbral lunar eclipse, meaning ifs a partial eclipse that leaves sections of the moon darkened by the earth’s shadow. No, it won’t be as spectacular as those “blood moon” eclipses. It’ll be subtler. The level of darkness it reached during the eclipse may or may not be apparent; it just depends on where you are when you view it.
In North America, the eclipse begins at 5:34 p.m. ET and ends at 9:53 p.m. ET, according to astronomy website EarthSky. The eclipse will be at its height around 7:44 p.m. ET.
If that’s still not enough, let’s throw in a comet (彗星)to the night’s festivities.
Comet 45P (it has a much longer name, but we won’t burden you with it here) is visible as it flies by Earth. The comet will get within 7.4 million miles of the planet as it makes its closest approach this weekend, according to Universe Today.
Comet 45P will be the most visible a couple of hours after the eclipse, so look to the skies again around 3 a.m. ET Saturday and find the greenish-blue light with a tail.
And don’t forget, a total big-time solar eclipse will streak across the United States on August 21st.
