Example Input: Article: DNA tells the story of the race to discover the structure of DNA, and the scientists who changed our understanding of the world and everything in it. The five-part series, to be broadcast from Thursday July 14 at 8:30 p.m. on ABC TV, also looks at the scientists' work for the future of mankind. The scientists were a small group of pioneers who explored a world too small to see. What they found there answered some eternal questions--What is life? How is it made ? Why are children like their parents? DNA is without doubt the most powerful substance on earth. The order of its chemicals determines whether a child has her mother's eyes or her father's smile. But as DNA shows, until 50 years ago, almost no one knew of its existence. All that changed when two unknown scientists - Jim Watson and Francis Crick -ran into a pub in Cambridge shouting that they'd found the secret of life. This declaration heralded a momentous discovery, not just for the human race but for the people involved. As this program shows, it was one of the most heated scientific races the world has ever seen. Dr Watson takes us back 50 years, guiding us through the tumultuous events that led to the creation of a double helix model being built by Dr Francis Crick and himself. He tells how he and Crick try hard to find the double helix first and win the Noble Prize. The program shows others involved with the DNA story, including Maurice Wilkins, who helped create the atom bomb. He became disillusioned with the science of death and chose the science of life instead, by looking for the structure of DNA.

Example Input: Article: A new report says the number of foreign students at colleges and universities in the United States increased by three percent last year. This has been the first obvious increase since 2001. American schools last fall had 583,000 foreign students. The record is 586,000. That was set in 2002 after many years of gains. But after that the numbers fell. The terrorist attacks on September 11th, 2001 led to more visa requirements. Now stronger efforts are being made to get more foreign students to study in the United States. China remained in second place in front of South Korea but behind India, whichsent almost 84,000 students last fall. The number of Japanese fell sharply by nine percent, although it remained in fourth place. There were three percent drops from Indonesia and Kenya, the only African country in the top twenty last year. But there were obvious increases from Saudi Arabia, Nepal and Vietnam. The number of Saudi students more than doubled, rising to nearly eight thousand. For a sixth year, the University of Southern California in Los Angeles had the most foreign students. Columbia University in New York was second. Other schools in the top five were New York University, the University of Illinois and Purdue University. Unlike American students in other countries, who often choose history and language study, the leading area of study in the USA was business and management. Second was engineering. The new report also says more than 220,000 Americans studied in other countries. That was during the 2005-2006 school year. It was a record number, and an increase of eight and a half percent from the year before. But only five percent of them stayed for a full year.
