We’ve learned bees can understand zero and do basic math. Now a new study shows their tiny insect brains may be able to connect symbols to numbers.
Adrian Dyer, a professor in the RMIT University, said the research showed brains far smaller than humans’ could know numbers. “Humans learn numbers as children, but being able to recognize what numbers really represent needs a certain level of cognitive (认知的) ability,” Dyer says, “Studies have shown primates (灵长类动物) and birds have this ability, but this is the first time we’ve seen this in insects.”
It’s important for humans to do the research. There are 86 billion neurons (神经元) in humans’ brains. Bees only have less than a million. If bees have the ability to learn something difficult to understand like human-made symbolic language, this will open up exciting new paths for future communication between humans and animals.
Studies have shown that a number of animals have been able to learn symbols of numbers, including parrots and monkeys. Monkeys were taught Arabic numbers and could order them correctly. An African grey parrot called Alex was able to learn numbers and could do simple calculation.
Understanding how tiny brains of bees manage information opens paths to technology, which is good for the future design of computing (计算) systems.

I was born in Bombay, India. When I was about 6 months old, my legs became paralyzed (麻痹的). My birth mother deserted (遗弃) me. I was adopted (收养) by an American family. I was taken to Spokane, Washington. It took me a long time to be able to walk, because I had to accept a number of operations.
When I was in the business school, one of my friends was training for a marathon. One day, she introduced me to an organization called Achilles International, which was a club for athletes with disabilities. It took me four months to get the courage to make the phone call. Dick Traum, the founder of Achilles, answered the phone. He asked me to show up on Tuesday and would lend me his bike. That was the first time that I had been able to feel the wind in my long hair. I rode really slowly, but it was the coolest feeling to ride a bicycle for the first time.
Later, I decided to take part in the Ironman World Championship. I was in a lot of pain, because I had to practice swimming, biking and running for over nine months.
On the day of the marathon, it took me 14 hours and 39 minutes to finish the Triathlon. After I crossed that finish line, I cried. I made it. It was my determination that made my dream come true.
