动物在长途迁徙过程中利用这一感应力给自己导航,鸟类则凭借这一感应力看到前方飞行的方向。
The complex tests involved examining the process by which light goes through a birds eye, which has intriguedthe scientific community fomore than 30 years.
这些复杂的试验包括观察光进入鸟的眼睛的过程,科学界在这方面已经研究了30余年。
In the late 1970s, the physicist Klaus Schulten concluded that birds navigate by relying on geomagnetically sensitive biochemical reactions in their eyes.
在20世纪70年代晚期,物理学家克劳斯 舒尔腾得出结论说,鸟类依靠眼睛内能够感应地磁的生物化学反应来导航。
Tests have shown that the special cells in the eye carry out this function using the protein cryptochrome.
测试表明,眼睛内部某些特别的细胞在蛋白隐色素的作用下能够实现这一功能。
Professor Repperts team used wild fruit flies and replaced their version of cryptochrome with the human equivalent then put them in a mazewith each wing wrapped in a metal coil.
里珀特教授的研究团队把野生果蝇眼内的蛋白隐色素换成人类的蛋白隐色素,然后将果蝇放在一个迷宫中,每只翅膀都用金属丝包裹起来。
They then sent a current through it so that the coil was magnetised in a way which mimicked Earths electromagnetic field.
