Papaya is the healthiest fruit with a list of properties that is long and exhaustive. Papaya favours digestion as well as cures skin irritation and sun burns. You can munch on it as a salad, have it cooked or boiled or just drink it up as milkshake or juice. The most important of these virtues is the protein-digesting enzyme in the milky juice or latex. The enzyme is similar to pepsin in its digestive action and is said to be so powerful that it can digest 200 times its own weight in protein. It assists the body in assimilating the maximum nutritional value from food to provide energy and body-building materials.

Papain in raw papaya makes up for the deficiency of gastric juice and fights excess of unhealthy mucus in the stomach, dyspepsia and intestinal irritation. The ripe fruit, if eaten regularly corrects habitual constipation, bleeding piles and chronic diarrhea. The juice of the papaya seeds also assists in the above-mentioned ailments.

The juice, used as a cosmetic, removes freckles or brown spots due to exposure to sunlight and makes the skin smooth and delicate. A paste of papaya seeds is applied in skin diseases like those caused by ringworm. The black seeds of the papaya are highly beneficial in the treatment of cirrhosis of the liver caused by alcoholism, malnutrition, etc. A tablespoonful of its juice, combined with a hint of fresh lime juice, should be consumed once or twice daily for a month.

A team from Cornell University, which is led by a scientist from India, has begun teaching a robot to understand instructions. These instructions are given by various speakers in the robot’s own language. This experiment tries to assess how adept the robot is at adapting to its environment. AshutoshSaxena, Assistant Professor at New York’s Cornell University has developed the software that can translate simple human sentences. One of his experiments has involved the simple act of making noodles from a packet. The robot is told in sentences to fill a pan with water. Place it on the stove, and heat the water. When it is boiling, the robot is instructed to put in the noodles. It has been found that the robot not only follows instructions but is smart enough to fill in the missing steps.

Saxena’s robot is also equipped with a 3D camera which scans its environment and identifies the objects in it, using this software. The robot has also been trained to associate the objects with their capabilities. Thus it knows that a stove can have objects placed on them and can heat things.

Saxena’s team used techniques called machine learning to train the robot’s computer ‘brain’. Thus the computer brain can associate entire commands given to it with flexibly defined actions.

Now answer the following questions briefly: ( 1x5=5marks)

1. What has Ashutosh Saxena developed at Cornell University?

2. What does the experiment try to do?
