There are records of fingerprints taken many centuries ago. The ancient Babylonians pressed the tips of their fingerprints into clay to record business trade. The Chinese used ink-on-paper finger impressions for business. However, fingerprinting wasn't used as a method for identifying criminals until the 19th century.

In 1858, Sir William Herschel was working as an official of the Hooghly district in Jungipoor, India.In order to reduce fraud , he had people living in the district record their fingerprints when signing business documents. A few years later, Scottish doctor Henry Faulds was working in Japan when he discovered fingerprints left by artists on ancient pieces of clay.This finding inspired him to begin investigating fingerprints.In 1880, Faulds wrote to his cousin, the famous naturalist Charles Darwin, and asked for help with developing a fingerprint classification system.Darwin refused, but sent the letter to his cousin, Sir Francis Gallon, who was an eugenicist . Gallon began collecting fingerprints and eventually gathered some 8, 000 different samples to analyze. In 1892, he published a book called "Fingerprints", in which he outlined a fingerprint classification system--the first existence.

Around the same time, Juan Vucetich, a police officer in Buenos Aires, Argentina, was developing his own version of a fingerprinting system.In 1892, Vucetich was called in to assist with the investigation of the two boys murdered in Necoche, a village near Buenos Aires. Their mother, Francisca Rojas, accused a neighbour named Velasquez. But when Vucetich compared the fingerprints found at the murder scene to those of both Velasquez and Rojas, _ matched Rojas' exactly.She admitted her crime. This was the first time fingerprints had been used in a criminal investigation.Vucetich called his system comparative dactyloscopy . It's still used in many Spanish-speaking countries.

Sir Edward Henry, in charge of the Metropolitan Police of London, soon became interested in using fingerprints to catch criminals. In 1896, he added to Gallon's technique, creating his own classification system, the Henry Classification System. It is the primary method of fingerprint classification throughout most of the world.

London (CNN) -- What do artificial whiskers and coffee-filled balloons have in common?

The answer is that they are both tools on experimental robots -- but they are also being put forward as possible ideas to help future planetary explorations.

"Shrewbot" is the latest in a line of robots developed by teams at the UK's Bristol Robotics Laboratory (BRL) that aims to test whether artificial whiskers could help a robot find its way around.

Inspired by the Etruscan shrew -- one of the world's tiniest mammals -- scientists wanted to find out if a robot could explore its environment using touch instead of vision, just as rats, mice and shrews find food in the dark.

Team leader Martin Pearson, who works at the Biotact project, said the research was primarily to assist biologists in their understanding of how an animal's touch sensing works.

But he added: "Future robotic applications for this kind of sensing could be in search-and-rescue robots operating in smoke filled buildings or for sub-sea pipeline inspection robots in the murky depths of the sea."

The idea has also been suggested as a way to explore planetary surfaces where there is limited vision. Speaking at a space conference at the UK's Rutherford Appleton Laboratory, robotics expert and co-founder of the BRL, Alan Winfield, identified it as one of a number of advancements that might be useful to space scientists planning future missions.

"I was speculating that whiskers could provide a planetary rover with the ability to feel its way around," he told CNN. What are the answers to this following set of questions: 1. Which is a newer robot type?

SEOUL, South Korea (CNN) -- South Korea bade farewell to former President Kim Dae-Jung Sunday in a ceremony attended by thousands of citizens, dignitaries and politicians.

South Korean Buddhist monks pray in front of a portrait of former president Kim Dae-jung during his funeral Sunday.

The solemn Sunday afternoon ceremony was held outside parliament, with a large portrait of Kim placed on a shrine surrounded by flowers.

The funeral followed six days of mourning for Kim, who died Tuesday of a heart failure.

Kim's age at the time of his death was in dispute, with some reports saying he was 85 while others placing it at 83.

Kim's state funeral was the second such ever given in the country, South Korea's Yonhap news agency said.

Another president, Park Chung-hee, was also accorded a state funeral after his assassination while in office in 1979.

Kim -- who was president from 1998 to 2003 -- won the Nobel Peace Prize in 2000 for trying to foster better relations with North Korea.

The watershed moment of his presidency came in June 2000 when he met North Korean leader Kim Jong Il, becoming the first South Korean leader to do so since the Korean War unofficially ended in 1953.

But rapproachment talks between the two sides hit a wall after conservative South Korean President Lee Myung-bak took office in early 2008 with a tougher stance toward the North than Kim and his successor, Roh Moo-hyun.

Ahead of the funeral, President Lee met with a visiting North Korean delegation, who delivered a message from Kim Jong Il expressing hopes for improved relations between the two countries. What are the answers to this following set of questions: 1. Who's image was being prayed in front of?
2. On what occasion?
3. Where was it at?
4. When had he passed?
5. Of what?
6. How long had they waited to hold the service?
7. What did they do during that time?
8. Was this the first service of this magnitude?
9. How many others have their been?
10. Who was that for?
11. When did he pass away?
