Among the fields in which moving even a small distance in the wrong direction can lead to disaster: surgery and robotic operations. With recent innovations like the da Vinci Surgical System, the latter is being deployed more and more to improve accuracy in the operating room.
And now, surgeons are starting to get a bit of robotic help from above—way above. The Canadian Space Agency’s robotic Canadarm boom and manipulator has been used for decades to snatch satellites and move astronauts around during spacewalks. Some of that same technology is now being applied for surgeries on Earth.
Survival of the fittest has served humans and our ancestors well for millions of years. We have developed sophisticated defense mechanisms, like highly specialized senses and immune systems that can thwart many of our greatest threats. And for the things our immune systems can’t defeat, we have developed advanced medical techniques to combat infection and disease.
Of course, we’re not the only creatures capable of adapting. Like all other living organisms, bacteria are constantly evolving. And because they multiply quickly and in large numbers, their rate of change dwarfs our own.
