[Q]: Article: Fatu Kekula is a hero. The 22-year-old Liberian nursing student, in her final year, managed to save the members of her immediate family from the Ebola virus, all without the help and convenience of a hospital. Kekula reduced the rate to 25 percent. Four of her family members were infected with the virus. Her father, Moses, her mother, Victoria, her sister, Vivian and her 14-year-old cousin, Alfred Winnie. Sadly, Kekula's cousin _ the virus. It's also impressive to note that while Kekula was treating her family members she managed to avoid Ebola entirely. On July 27, Kekula's father, Moses, went to a hospital in Kanata, after his blood pressure rose sharply. The only reason the hospital had a bed to offer him was because someone had just died. But the staff in the hospital didn't realize the patient died from an Ebola infection. Shortly, after he was admitted to the hospital, Moses developed a fever, started vomiting and was suffering from diarrhea. Once nurses started dying of Ebola, the hospital shut down and Moses had to leave. Kekula drove 90 minutes to Monrovia, the capital of Liberia, to seek treatment. Three hospitals turned them away because there is no spare bed for patients at all. Kekula made the drive back to Kanata to another hospital. They told Moses he had typhoid fever and did very little to treat him. So Kekula took him home. Once he was there, he infected three other family members. Her mother, sister and their cousin who was living with them. Kekula only lost one patient, her cousin. Her method proved so effective that international aid workers, including UNICEF, began teaching it to others in West Africa who may not be able to get to hospitals for treatment. Her father, mother and sister were already recovering when space became available at the JFK Medical Center on August 17. Alfred passed away at the hospital the next day. Kekula's father, Moses said, "I'm very, very proud. She saved my life through the almighty God."

[Q]: Article: A Russian legend has a story about the origins of cats. The cat's coat, it was said, was originally designed for the dog, but the dog became so impatient when coats were being handed out that he was told to wait at the back of the queue. The cat was given the fur instead of the dog. This, according to Russian folk storied, is the origin of why dogs dislike cats. A nameless cat with a taste for travel flew for three weeks between New York and Tel Aviv in 1984. It escaped from its owner's cat-box in the plane's luggage compartment on the first trip and all efforts to get it out with bowls of milk and food failed. After nearly 80,000 miles of flying the airline called in a vet who got it out. The Chinese attitude to the cat was not clear. Cats were welcome for their ability to kill mice and were considered suitable pets for women. On the other hand, they were suspected of bring bad luck into the home. In the days before the invention of the watch, it was said that they used their cats as clocks. The pupils of the cat's eyes were believed to gradually change shape with the position of the sun in the sky. At midday they were a narrow line and they gradually became rounder until sunset. Britain's cleanest cat is undoubtedly Harvey, a five-month-old Persian who climbed into his owner's washing machine. He went through a ten-minute wash cycle before someone noticed him through the glass door, and pressed the "stop" button. Harvey was soon back to his usual self. Cats seem to be able to sense earthquakes. Josie, who lives in California, warned her family of a quake in 1971. She wore her owners. Mr. and Mrs. Miller, at 5:50am by jumping onto the bed and running around. When the Miller followed her out of the house, Josie ran off. The earthquake was only a small one, but the cat raised the alarm every time there was a quake after that.

[Q]: Article: A boy won the grand prize at the 2012 International Science and Engineering Fair, the largest high school science competition in the world. The Maryland teenager Jack Andraka is the youngest winner of the $75,000 prize. He was chosen from among l,500 students in 70 countries. Jack invented a test for pancreatic cancer( ). He started to learn it after losing a close family friend to the disease. "I went on the Internet and I found that 85 percent of all pancreatic cancers are found late, when someone has less than a 2% chance of survival he says. "and I was thinking, 'That's not right and we should be able to do something."' He found that early discovery is important to increase the chances of suryiving the disease. Jack asked to work in a laboratory at Johns Hopkins University in Baltimore and was allowed. There he developed a simple paper test. which can recognize the disease in a single drop of blood. His test has proven correct 90% of the time. It also is 100 times more sensitive than other tests. "It costs 3 Jack's success wouldn't have been possible without Anirban Maitra . a professor at Johns Hopkins, who was the only person among the 200 researchers Jack wrote to and who showed interest in his project "I was very surprised that it was a 15-year-old who was writing this. I wanted to meet this clever young man and see what he wanted to talked about. so I called for him over for an interview," Maitra said. Jack worked in Professor Maitra's laboratory completing his project in 7 months. The government bas given the Maryland teenager patent rights to the pancreatic cancer test. He is now talking with companies about developing the test into a simple product .
