Monkeys test 'hardworking gene'

The monkeys were back to normal after 10 weeks of treatment
Scientists in the United States have found a way of turning lazy monkeys into workaholics using gene therapy.
Usually monkeys work hard only when they know a reward is coming, but the animals given this treatment did their best all the time.
Monkeys are rather like people in their approach to work - at least, those who live in a laboratory and learn to press levers for rewards of food and water.
They concentrate on their task only when the moment of delivery approaches.
"Monkeys under the influence of the treatment don't procrastinate"

Researchers at the National Institute of Mental Health near Washington DC, led by Dr Barry Richmond, have now developed a genetic treatment which changes their work ethic markedly.
The genetic treatment consists of blocking an important brain chemical - dopamine.
"Normal monkeys and people procrastinate - tend not to work very well when they have a lot of time to get the job done, and work better when the reward is nearer in time," Dr Richmond says.
