姿势和摆动控制蝴蝶飞行
姿势 摆动
2016/3/21
蝴蝶利用较大的翅膀和缓慢的扑闪在空中飞行。据了解，蝴蝶每秒钟拍动约10次翅膀，而蜜蜂要拍动200次左右。一个最新模型展示了它们如何控制这种不平稳且飘忽不定的飞行：正确的姿势加上一点点摇摆。
小蜻蜓打破昆虫迁徙纪录（图）
小蜻蜓 昆虫迁徙
2016/3/8
请让开，帝王蝶。新的远距离昆虫飞行纪录诞生了：一种长度仅有4厘米但能挥舞着翅膀飞越海洋和大陆的小蜻蜓。这个名为薄翅蜻蜓的物种（如图所示），在寻找水池产卵时可能会迁徙1.4万～1.9万公里。在昆虫当中，此前的纪录保持者——帝王蝶在每年的“旅行”中总共飞越8000公里左右的路程。北极燕鸥则创下了所有动物中飞行距离最长的纪录——每年飞行约4万公里。科学家曾怀疑蜻蜓是一个能跨越全球的单独种群的成员。而一项...

冷冻三十年 水熊虫 复苏
2016/1/21
日本国家极地研究所的研究人员首次将冷冻30多年的缓步动物“水熊虫”成功复苏，这将提高人们对隐生生物体长期存活机制及条件的理解。相关研究成果发表在最新一期的《低温生物学》上。水熊虫也叫水熊，是对缓步动物门生物的俗称，有记录的约有900余种，大多是世界性分布的。它们的体型极小，最小的只有50微米，而最大的则有1.4毫米，必须用显微镜才能看清。其是地球上已知生命力最强的生物，能在冷冻、水煮、风干的状态下...
