谁认为老鼠，一些黄金和有机硅可以变成一个小的黄貂鱼？
As odd as it sounds, a team of scientists have recently conducted a research project, where they used 3D printing and genetic engineering to create a biohybrid animal.
This tiny swimmer moves by using the mesh rat heart muscle cells inside its silicone body to pulse, allowing the tiny flipper areas of its body to swim through water. It has a skeleton made from 3D printed gold, which allows it to store energy for movement.
Scientists are able to control the ‘nickel sized’ creature using light cues.
硅树脂的关键是使用大鼠心脏细胞，因为它们使其很小，同时能够自行移动。如果使用电动机，那将会大得多。除了允许它移动外，肌肉还可以充当微小黄貂鱼的控制系统。通过基因工程设计，这些细胞经过设计对光敏感，使科学家可以使用闪光灯来控制它：闪光灯的速度控制着生物移动的速度，同时在一侧闪耀光线会导致其改变方向。
细胞也被形状，以便细胞的网格与黄貂鱼的形状一起使用。
The project was lead by Harvard’s Disease Biophysics Group, which was led by Kevin Kit Parker, with a team of scientists from the University of Illinois, University of Michigan and Stanford Medical Center.
Such development is incredibly exciting to see, though it’s also slightly worrying, as plenty of Hollywood movies have made it clear that artificial creatures much like this stingray are never a good idea.
但为什么？
尽管我有点诱惑，但很害怕拥有宠物，但这个项目无疑是一项研究练习。人工动物当然对于多种应用，例如治疗和手术，尽管有多种应用也可以有用。希望获得的知识能够帮助研究发展人工心。这种微小的人造动物也可能是人造认知界的一步。
