She opened the cage and made a coaxing motion. “Come here, Einstein.” A fat, white rat dashed out the door onto her hand and scrambled up her right shoulder. His neon-blue eyes gave off an icy intelligence. The change in eye colour was one of many side effects of her tests Jane still couldn’t explain. The rat whipped its tail into her hair for balance, hopping from paw to paw.
“Settle down, boy,” she said. She carried Einstein back into the lab with its virtual maze and extended her hand. He raced down her arm to the large trackball and made little jumps in anticipation of the race. As Jane clamped him gently into the metal rig that held him in place, he stopped jumping. Einstein differed from the other rats—he never struggled when Jane locked him in place. The other rats fought against the harness, making it difficult to complete the test preparations.
A two-dimensional overview of a simple maze flashed on the screen. Without hesitating, Einstein rolled through the maze on his trackball, completing the challenge in seconds.
“Too easy,” Jane said. “You don’t even deserve a prize.” Despite this, she stroked the rat’s head and gave him a small piece of cheese. Einstein snapped it up in his front paws. As soon as he devoured it, he pulled against his harness and chattered at Jane.
“Relax, big fella.” She tapped on her keyboard to reconfigure the course before bending down to eye level with Einstein. “Now the real challenge begins.” He stared into her sea- green eyes. The small rodent had the intense focus of a fighter about to get in the ring.
A second maze flashed on the screen. There was a straightforward solution that was long and twisting. A second solution existed, but so far, none of the rats had figured it out. The second path had two tiny virtual teleportation pads. If the rats stepped onto one of the pads, they were transported to a corresponding location in a different part of the maze. For this test, the pads would save precious seconds. “Go,” Jane shouted, starting the timer. Einstein didn’t budge. Instead, he looked back and forth between the obvious path and the first teleportation pad.
“Clock’s ticking,” Jane said to herself in frustration.
Einstein shrieked as he noticed the decreasing progress bar. A tentative paw step forward cleared the maze overview and put him in a six-inch-high virtual hallway. He waddled straight to the teleportation pad but stopped short. He turned his gaze to Jane as his whiskers moved back and forth, up and down. Jane stared back, willing him to make the right move.
The rat rolled forward on his trackball across the pad. The screen flashed, and he teleported to within a few steps of the exit. With a final glance at Jane, he spun through the gate with twenty seconds left on the clock.
Jane clapped her hands. “You did it.” She reached toward him. He clambered up her arm, slower now that he was out of the virtual world. She gave him a piece of cheese and returned him to the steel table.
