【正文】 ld devices — like Cornell’s GPS system — that are smaller, lighter and more efficient than anything they’ve made before, they could give scientists access to entirely novel information. 109 ?It’s very difficult to measure a living anism’s internal processes without somehow restraining it and disturbing its natural behaviors. But the more scientists learn about safely fusing living animals and technology, the better they bee at monitoring the many important biological processes that happen inside those animals, without keeping them caged up or tethered in labs. ? Bionic bugs could soon provide biologists with an unprecedented ability to study insects in their natural environment. Imagine breeding cyb moths and beetles outfitted with tiny selfsufficient GPS monitors and chemical sensors — then releasing them to the skies and forests. 110 ? ―We want to monitor body temperature, metabolic rate, flight speed — we want to map where they are going, map their life history. A lot of this is really unknown,‖ said VandenBrooks, coauthor of the Berkeley study. ―Animal tracking devices and how long they last are an important issue,‖ said Cornell’s Reissman. ―Making better, longer lasting devices would be very advantageous to understanding biological systems.‖ 111 ? Focusing on the nervous systems of insects has also proven beneficial to scientists. It might seem trivial to study the brains and behaviors of bugs, but nerves — the individual cells of the nervous system — are so plicated that researchers need to tightly concentrate their efforts to make progress. ? ―It’s a very valuable way to approach and study neuroscience,‖ the University of Utah’s Harrison said. ―It turns out biology is really, really plex. A housefly has a quarter million neurons in its brain — and that’s just a housefly!‖ 112 ? ―It’s such a scifi approach that some people see no feasibility or use for this research,‖ said Reissman, ―but the truth is that each of these research areas needs advancing. We’re going to keep seeing good science e out of this.‖ 113 不會漏氣的仿蜂巢輪胎 ? 我們的身邊日夜都陪伴著大量昆蟲和蜘蛛綱動物,它們形態(tài)不一,體型各異,但由于長相恐怖,我們幾乎不會將它們作為思考的對象。 87 88 89 90 91 尺蛾 =尺蠖 92 Bionic Bugs ?
