They travel in groups, noses just inches away form GPS screen. Suddenly a boy shouts “I found it!”, grinning and walking away from the group.
The others focus on their screens. “Me. too!” shouts another a moment later, until all six kids are crowded around a tree, pulling out a plastic bottle painted to look like tree bark. It doesn’t seem like much from the outside, but everyone gathers around, eager to see what’s inside.
This is geocaching, a high-tech game played using coordinates (坐标) and global positioning systems to find hidden “treasures”.
It’s open to anyone—hiders or seekers—with a GPS and access to www.geocaching.com, where more than half a million users download and upload the coordinates of nearly 1 million hidden caches (储藏物) and write about their experiences in this worldwide hunt.
Although some adventures can take hours or even days, the contents inside the actual cache usually aren’t valuable—often just a book or a small trinket (小饰品).
But participants aren’t in it for the treasure. They say it’s a great way to exercise. Or it brings them to remote destinations or historical sites. Some consider it an extreme sport, looking for geocaches hidden in mountains or in other nearly inaccessible locations.
Jeffrey Howe, 41, sees it as an opportunity to take kids on adventures to unfamiliar places. The youths at the shelter mostly come form the city, but geocaching has taken them to parks, the suburbs, and, once, to a 498-meter-high mountain.
“Geocaching is a way to give kids the idea that there’s a whole world out there other than what they know from their home neighborhoods and video games,” he said.
How does it work? Log onto the Website and enter your zip code (邮编), then search for caches near your location. Although posted coordinates will take a GPS within about 4.5 meters of a cache, a good hide will require seekers to do a bit of hunting around. Caches can’t be buried underground, nor can they be hidden on private property (财产), in dangerous locations or in some national parks.
Posts written about the find—whether successful or unsuccessful—are an important part of the game, with users proudly recording the places to which they’ve traveled.

The UN Environment Programme says that rising temperatures could mean the end for some migrating animals.
Migrating or mobile animals move through several environments as they travel away from the cold of winter to warmer areas. Birds may fly from one part of the world to another, perhaps stopping at feeding grounds on the way. Whales and turtles (海龟) cover vast areas of ocean. The report says that changes in any one of the places which these animals use can cause serious harm. "Obviously these animals have developed their travelling patterns over thousands of years. But climate change is almost certain to be extreme over the next 25 to 50 years and it is extremely unlikely that these animals can change their habits fast enough," said the report author Dr Robert Hepworth.
Hardest hit by rising temperatures are turtles. Scientists have found that at higher temperatures, turtles produce far more female eggs than male ones. In parts of Malaysia, turtle birthing sites are producing only females, the report says. It also provides evidence that some turtles are more likely to develop cancer as the waters get warmer.
With birds, the main problem is climate-related damage to important areas at either end of the travels or at resting places along the way. About one-fifth of migrating birds are now in danger because of climate-related changes including rising sea levels, land loss and more violent storms, the report concludes.
Other animals picked out as particularly in danger include:
· the North Atlantic Right Whale, whose main food (tiny shrimp) is disturbed by the change in ocean flows and
· the White-Nose Dolphin, which is out-competed by other kinds of dolphins in warmer waters.
The report is not all bad news. Even with major climatic changes, protecting the environment can still help mobile animals to recover. "We need governments to start taking action at the national and international lever. “The clock is running.” said Dr Hepworth. And some animals are already adapting, with the report mentioning whales that are changing their feeding behaviour, finding new feeding grounds and new foods to eat.

Motorists who used to listen to the radio or their favorite tunes on CDs may have a new way to entertain themselves, after engineers in Japan developed a musical road surface.
A team from the Hokkaido Industrial Research Institute has built a number of“melody roads,”which use cars as tuning forks to play music as they travel.
The concept works by using grooves(凹槽).They are cut at very specific intervals in the road surface. The melody road uses the spaces between to create different notes.
Depending on how far apart the grooves are, a car moving over them will produce a series of high or low notes, and designers are able to create a distinct tune.
Paten documents for the design describe it as notches “formed in a road surface so as to play a melody without producing simple sound or rhythm and reproduce melody-like tones”.
There are three musical strips in central and northern Japan—one of which plays the tune of a Japanese pop song. Reports say the system was invented by Shizuo Shinoda. He scraped some markings into a road with a bulldozer before driving over them and found that they helped to produce all kinds of tones.
The optimal speed for melody road is 44kph,but people say it is not always easy to get the intended sound.
“You need to keep the car windows closed to hear well,”wrote one Japanese blogger.“Driving too fast will sound like playing fast forward, while driving around 12mph[20km/h]has a slow-motion effect, making you almost car-sick.”
