13、the first robotic fly. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly.

14、d so we have to develop them all on our own，” said Robert Wood, a Harvard engineering professor. They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has lots of interdependence(互相依賴) of the individual components, each of wh

15、ich individually has to perform well，but then has to be matched well to everything it's connected to，”said Wood. While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gather

16、ing work at rescue sites, in farmers' fields or on the battlefield. “Basically it should be able to take off, land and fly around，” he said. Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board cou

Some curl up their leaves, others produce chemicals to

24、 make themselves taste bad if they sense animals drooling on them, chewing them up or laying eggs on them—all signals of an attack. New research now shows some flora can feel a plant－eating animal well before it launches an attack, letting a plant prepare a preemptive(先發(fā)制人的) defense that even works

25、against other pest species. When ecologist John Orrock of the University of Wisconsin－Madison sprayed snail slime—a liquid the animals release as they slide along—onto soil, nearby tomato plants appeared to notice. They increased their levels of an enzyme(酶) , which is known to prevent plant-eating

26、 animals. “None of the plants were ever actually attacked，” Orrock says. “We just gave them cues that suggested an attack was coming, and that was enough to cause big changes in their chemistry.” Initially Orrock found this defense worked against snails; in the latest study, his team measured the s

27、limy warning's impact on another potential threat. The investigators found that hungry caterpillars(毛蟲), which usually eat tomato leaves greedily, had no appetite for them after the plants were exposed to snail slime and activated their chemical resistance. This nonspecific defense may be a strategy

28、 that benefits the plants by further improving their overall possibilities of survival, says Orrock, who reported the results with his colleagues in March in Oecologia. The finding that a snail's approach can cause a plant response that affects a different animal made Richard Karban curious, a plan

The research was comprehensive, he adds, but he wonders how the tomato plants felt chemicals in sna
