蓝色章鱼是全新物种

2015 年在加拉帕戈斯群岛进行深海考察的科学家在查看遥控潜水器拍摄的影像时，发现了一只体型娇小、通体呈蓝色的章鱼，它位于水下约 1773 米处。科学家捕捉了这只章鱼以进行进一步分析。研究人员如今得出结论：这只体型小到可以放在手掌的可爱小生物属于一个全新物种。研究报告发表在《Zootaxis》期刊上。小章鱼被保存在储藏室中。由于它的独一无二，且极不可能采集到另一只，科学家不愿意对其解剖进行彻底的物种鉴定分析。因此研究团队选择了 mini-CT 扫描，研究表明这种生物手臂很短，臂上的吸盘很少，没有墨囊，皮肤光滑，且有一颗巨大的脊齿。他们将该物种命名为 Microeledone galapagensis。

富铁免疫细胞帮助信鸽导航

迁徒鸟、海龟等动物似乎具有感知地磁场的能力，能利用地磁场进行导航。根据发表在《科学》期刊上的一项研究，信鸽肝脏中的富铁免疫细胞可能赋予了其磁罗盘的能力。对信鸽组织薄片的分析发现，其肝脏巨噬细胞富含铁蛋白，但它在脾脏中很少，且在喙和大脑中完全不存在。电子显微镜的进一步观察发现，巨噬细胞紧邻神经元，而这些神经元都与中枢神经系统相连。研究人员设计了一个试验检验富含铁的巨噬细胞是否能像磁罗盘一样为信鸽指引方向：他们使用名为 clodronate liposomes 的药物抑制巨噬细胞的活性。研究团队训练了 34 只信鸽。白天信鸽利用太阳的位置确定方向。当阴天或完全被云层遮蔽时，它们依靠磁感应辨别方向。研究团队给 18 只信鸽注射了 clodronate，24 小时后当云完全遮蔽阳光时将它们逐一放飞。这些信鸽都佩戴了 GPS 发射器，研究团队能实时追踪其飞行轨迹。所有 18 只信鸽都迷路了，直到天空放晴才返回。16 只对照组的信鸽都没有迷路。研究人员表示，如果铁蛋白辅助导航机制得到证实，那么它可能具有普适性，适用于从蜜蜂到蝙蝠，到鲸鱼和鲨鱼等各种动物。
