Article: Have you seen a yellow-and-black salamander ? How about a scarlet frog? Scientists haven't spotted either species in more than 20 years. What happened to them? Are the creatures still out there, or are they extinct? Those are questions that scientists hope to answer. They recently set out around the world in search of those and other long-missing amphibians. An amphibian is an animal that spends part of its life in water and part on land. Frog, toads , and salamanders are amphibians. The experts are looking for about 100 species. They are searching at least 14 countries on five continents. They will look for the salamander in North America. They hope to find the scarlet frog in South America. They're also looking for species in Africa, Asia and Australia. Scientists are hopeful that they'll find the amphibians--and soon! If the creatures are out there, they may need help. Many amphibians are endangered. The animals face many dangers including pollution and diseases. People cut down the forests where they live. "If researchers can find the missing creatures, they might be able to figure out how to save them," explains expert Robin Moore. He began searching for the amphibians earlier this month. "This search will tell us a lot about how amphibians are doing," Moore told WR News. "I don't know what we will find, but that makes the search even more exciting." Lost in the Wild Scientists' hunt for missing amphibians is under way. Read about some of the species they hope to find. Turkestanian salamander This salamander is a mystery to scientists. Experts found a few of them more than 100 years ago, but none have been seen ever since. Gastric brooding frog Experts first discovered this frog in 1914 in eastern Australia. It may be extinct because of disease and habitat loss. Rio Pescado stubfoot toad Last sighting: 1995, in South America Scientists hope to find this spotted toad in rivers and rainforests in Ecuador. The animal faces threats including pollution and disease.

Article: Donald was shaken by thunder on the bed before he could count "one thousand one". Then he heard the smoke alarm go off. He went downstairs quickly to investigate. When he opened the door to the basement , flames exploded out. Donald fled back upstairs to call 911 but the phone didn't work. When he tried to go downstairs, he was stopped by a wall of flames. He had to use a towel to cover his mouth. His house was three miles off the main road and so well hidden by trees that Donald knew calling for help would be useless. Actually, he didn't even try to do that. About one mile away lived Donald's closest neighbor, Jeremie. When he heard some sounds, Jeremie jumped out of bed, holding a phone and a flashlight, and went towards the noise. He dialed 911 the instant he saw the flames. When he came close to the house, Jeremie knew he'd better wait until rescuers came. But he didn't want Donald to die in the fire. Without hesitation , he rushed into the house. He shouted, "Donald, where are you?" Then he had to run outside to catch his breath. After one more attempt , he gave up and circled around back. He saw Donald on the second-floor balcony, but there was no way to get to him. Suddenly, he noticed a ladder. He dragged it over to the balcony and pulled Donald down just when the second floor fell down. Within the year, Donald built a new two-story wood house at the site of the fire. Jeremie and Donald don't run into each other regularly, but Donald knows that if he ever needs help, Jeremie will be there.

Article: When Kathryn was 6 years old, she sat outside for three hours at her home and did not make a sound.Her parents wondered why she was so quiet, only to discover that she was drawing a picture of a flag outside. She recalled. "That's what I wanted to do that day," said Kathryn, who is now 23 years old. And in the future, she continued to do art as a hobby. Recently, Kathryn was named Lake Placid's first artist in the neighborhood. She will be there for at least four weeks and possibly more. During that time, she will teach an art class and focus on her own art. Much of her work includes creating photos. She said: "There is always something there that you haven't included, so you can never stop when painting a photo." Kathryn ended up as the first artist just by chance. She said her sister was on vacation in Florida and looking for a job in Lake Placid. The sister got the job and moved there. Kathryn said she visited her sister and was ordered to do wall paintings inside a building. Later, her sister saw a demand for an artist on line and suggested she should apply. Kathryn said she's the first artist in her family, but added that her parents are creative. Her father loves to create things from wood, she said. "Anything you can make out of wood, he has made it," she said. Her own creativity with art continued through college. While at college, she was once employed to recreate a photo of a couple on a vacation to Florida and one of a sunset in either North Carolina or South Carolina. Kathryn said she's looking at other forms of art. The time she spends here will help her to "figure out who I am as an artist," she said.
