If you had to grasp a tiny delicate object such as a blood vessel, doing
so with traditional tweezers would be a very painstaking process – just
a little too much pressure, and the object could be crushed. Instead,
scientists from Iowa State University have developed miniature coiling
tentacles for doing the job. They're even capable of holding an ant
without harming it.
