The vast jungles of the Amazon rainforest are home to tribes(部落)mostly isolated(隔绝的)from the outside world,whose way of life,largely unchanged for hundreds of years,is now increasingly threatened by modern civilization.
Now, scientists discover they can monitor these“uncontacted tribes”using satellites,which would allow inexpensive and safe tracking of these tribes in order to protect them from outside threats.
In order to help conserve these uncontacted Indians,researchers need accurate estimates of their populations.One way to collect this data involves flying over their villages,but such overflights are both expensive and could fill these native peoples with fear.Another strategy involves meeting individuals on the ground,but among other risks,scientists could accidentally spread disease to members of the tribes.
Instead,scientists investigated whether satellite imaging could monitor uncontacted tribes. The result was inspiring.They confirmed their locations and measured the sizes of their Village,houses and gardens.“We can find isolated vinages with remote sensing and study them over time.”Walker told Live Science.“We can ask:Are they growing?Do they move?”
Surprisingly,based on the sizes of the houses and Villages,the scientists find the population densities of these isolated villages are about 10 times greater,on average,than other villages of native Brazilian peoples.This may be due to the fact that they have to live closer together because they are not as good at clearing the forest,since they lack modern devices like chainsaws and tractors,the researchers said.The tribes may also be afraid of spreading out due to fear of being attacked by outsiders,Walker said.
The researchers now plan to focus on 29 more isolated villages to“look at their ecology—that is.distance from rivers and roads—and use this to model where else we can find more isolated villages,”Walker said.

Close your eyes and picture the city of Paris.Now imagine the city without its most famous landmark:the Eiffel Tower.
The unthinkable almost happened.
When French engineer Gustave Eiffel built this tower for the Paris World’s Fair of 1889,it was controversial.The iron structure contrasted(对比)sharply with the historic stone buildings of Paris.Eiffel’s four-legged iron archway was supposed to last only 20 years.That’s when Eiffel’s permit to operate the building would expire(过期)and the city could choose to tear it down.
Yet from the beginning.Eiffel had a strategy to save his building.If the Tower was linked to important research,he reasoned,no one would dare to take it down.So he would make it a grand laboratory for science.
Scientific research began just one day after the Tower opened to the public on May 6,1889.Eiffel installed a weather station on the Tower’s third(and highest)floor.He connected instruments by wire to the French weather bureau in Paris.With these,he measured wind speed and air pressure.
In 1903,still worried that his building might be torn down,Eiffel got a clever idea.He asked the French military to conduct its own research on radio communications at the Tower.He even paid the army’s costs.
French army captain Gustave Ferrié worked from a little wooden house at the base of the Tower's southern pillar.From there,he made radio contact with forts around Paris.Convinced of the importance of radio communications,the army set up a permanent radio station at the Tower.In 1910,the city of Paris renewed the structure’s permit for another 70 years.
This year marks the iconic structure’s 125th birthday.Over the years,research conducted there has brought dramatic and unexpected payoffs.During World War I,for instance,the French army used the Tower as a giant ear to receive radio messages.It even led to the arrest of one of the war's most famous spies.

A broad smile spreads across the faces of Martyn Sibley and Srin Madipalli when asked where they were when they decided to launch an online lifestyle magazine for disabled people.“On the beach.”they reply.“We’ve both travelled a lot but we wanted a real adventure,”Sibley says of the California road trip during which Disability Horizons was conceived(设想).
Sibley,whose professional background is in marketing,has been writing his own blog since 2009“about what I got up to,everyday stuff about living with disability”,he says.He describes how while“wandering on the beach together”Madipalli suggested branching out beyond a oneperson blog.
Why did they want to create a“lifestyle”magazine for the disabled people?The pair,both in their 20s,say they wanted to produce something“positive and inspiring”that would tell about the lives of disabled people as they actually were.They were especially eager to produce something that showed young disabled people“what it was possible to do with their lives”,says Sibley.
In less than a year,Disability Horizons has had more than 50 regular contributors and attracted a reader base of more than 20,000 people,more than a third of whom are in the US.
Sibley and Madipalli have a genetic disease that causes progressive muscle wasting and loss of movement.They are wheelchair users and have been good friends since growing up in London and Cambridge.Listening to them joke,it makes perfect sense that their shared optimistic outlook has spilled over into the magazine.The site covers topics ranging from books and travel to clubbing and photography.“It’s definitely a mix.”Madipalli says.

My parents and I went to the park last Sunday. There were lots of visitor standing in front of ticket window. We waited a long time and buy three tickets. In the Tiger Mountain of the park, I was too eager to see the fierce frightening animals that I quickened their steps through the crowd. Unfortunately, I got separated from my parents. I had a hard time look for them, but I had no lucky. Wandering in the park, I felt alone without any companions. Bad still, I had no money, so I had to walk to home, covering as much as 5 kilometers.
