Research published on Thursday in Science shows that the insects puncture the plants leaves, which causes th
21、em to flower about 30 days earlier than they otherwise would. How the technique developed and why the plants react by blooming remain unclear.Consuelo De Moraes, a chemical ecologist at the Swiss Federal Institute of Technology, says she and her teammates were observing one kind of bumblebee in an u
22、nrelated experiment when they noticed the insects were damaging plant leaves and wondered why. “At first we thought they might be feeding on the plants,” she says. And because previous research had shown stress could cause plants to flower, they also wondered whether the bees might be creating bloom
23、s on purpose.To find out, the team placed bumblebees together with tomato plants in cages. The bees soon cut several holes in the leaves of each plant. As a test, the researchers tried to copy the bumblebee damage in additional plants with a knife. Both sets of plants with injured leaves bloomed fas
24、ter, but the ones punctured by the bees flowered weeks earlier, suggesting that chemicals in the insects saliva(唾液) may be involved as well.Next, the researchers moved out of the laboratory to see whether bumblebees would continue to damage nonflowering plants near their nest even if blooming plants
25、 were available farther away. They did so. The findings suggest the bees behaviour is an adaptation that improves foodhunting efficiency.In the future, scientists could test how the behaviour may have developed and how widespread it is among other wild bumblebees, as well as what is happening in pla

30、s type of map isnt available yet. But it could be very soon. In 2014, the WorldView3 satellite was sent into space. Even though it orbits Earth at more than 370 miles (600 km) away, it can take images of objects on Earth that are just 10 inches (25 cm) across. Looking all the way from outer space, i

33、ersons knowledge. Ray Purdy of University College London told CNN that he couldnt imagine what this could mean for privacy. “Most satellites are commercially owned, so if you have money, you can have that imagery. It means anyone can spy on anyone,” he said.At the same time, live, detailed maps of t
34、he Earths surface could aid humanity in amazing ways. Satellite images can help experts track storms as they form and chart their paths. At high detail, live maps of a disaster area could quickly reveal people in need of rescue as well as the safest routes in or out. Satellite images are already hel
