A mouse looked through the hole in the wall to see the farmer and his wife open a pckage, and he was devastated to discover it was a mousetrap. Returning to the farmyard, he warned everyone. “There is a mousetrap in the house! There is a mousetrap inthe house! There is a mousetrap inthe house! ”

    The chicken raised her head and said, “Thanks for your warning. Mr. Mouse, but why should I be bothered by a mousetrap?” the pig sympathized, but said, “Wow, Mr. Mouse, I'm sorry for you I can tell this is a great concern to you, but it is none of my business.” The mouse returned to the house, head down and depressed, to face the farmer's mousetrap alone.

The very night a sound was heard throughthe house—-like that of a mouse trap catching its prey. The farmer's wife rushed to see what was caught. In the darkness, she did not see it was a snake whose tailwas caught by the trap, and it bit her. The farmer rushed her to the hospital and she returned home with a fever.

    The farmer killed the chicken to make fresh chicken soup for his wife, but her sickness continued. Frineds and neighbors came to visit her, and to feed them, the farmer butchered the pig. Then she died. So many people came for her funeral that the farmer had the cow cooked to provide enough meat for all of them.

    The mouse looked upon it all from his hole in the wall with great sadness.

    Green tree ants are important builders in the rainforest. They're like the worker bees of the ant world. The native forest of Thala Beach Nature Reserve is the natural home of these insects.

    They climb all over the tree that contains their nest and protect it from enemies with great fierceness. The ants are often in the fruiting trees of Tropical North Queensland. When an animal tries to help themselves to some tasty fruit, they find themselves attacked by a powerful, frightening army of green tree ants! Their bite is not very painful but many ants attacking at the same time can be extremely uncomfortable.

    The nests are large and constructed by sticking the leaves at the end of branches together to create a home looking roughly like a globe. Most of the nest construction and weaving is conducted at night. A mature colony of green tree ants can hold as many as 100,000 to 500,000 workers and may include as many as 12 trees and contain as any as 150 nests. Green tree ant colonies have one queen and a colony can live up to eight years.

    However, the ants are so busy that they fail to spot a dishonest figure. There is a spider called the Salticid spider, or the jumping spider, as they are sometimes referred to, which has excellent eyesight and is only active during daylight, weaving a protective covering of silk to spend the night in. Interestingly, the Salticid spider does not look like a green tree ant. Instead, it chemically copies green tree ants' smell. Effectively pretending to be an ant, it goes into the green tree ants' nest, enters the nursery and feasts on their babies. Green tree ants don't have good eyesight and smell everything with their antennae (two long thin parts on an ant's head). Therefore, the ants think the spider is another ant and ignore its presence within the nest.

    Next time, as you wander around Thala's native forest, keep an eye out for these busy little creatures. Look up into the trees and you'll likely spot their nests.

    Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.

    "I think we are knocking at the door of immortality(永生)," said Michael Zey, a Montclair State University business professor and author of two books on the future. "I think by 2075 we will see it and that' s a conservative estimate(保守的估计)."

    At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what has been possible in the past. "There is a great effort so that people can live from 120 to 180 years," he said. "Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years."

    However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.

    Scientists also differ on what kind of life the super aged might live. "It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?" said Leonard Poon, director of the University of Georgia Gerontology Centre. "At present people who could get to that point are not in good health at all."

    Of all the mountain gorillas that veterinarian Mike has treated in the past 18 years, a gorilla named Ijabo stands out the most. When Ijabo was three days old, an examination showed that one of his legs was badly damaged. Mike removed Ijabo's leg below the knee. Five years later, Mike says Ijabo is doing well. “I still see him every now and again,” Mike told TFK. “It's heartwarming.”

    Mike is a co-director of Gorilla Doctors. The organization provides medical care to ill and injured mountain and Grauer's gorillas. Its 16 veterinarians work in national parks in the Democratic Republic of the Congo, Rwanda, and Uganda. For years, the apes have fallen victim to habitat loss, poaching, and disease. According to their website, Gorilla Doctor's task is to save the apes “one gorilla at a time”.

    The doctors treat mostly gorillas that are accustomed to humans. Trackers, guides, and veterinarians check on habituated gorillas in the field several times each week. Sometimes, a gorilla has a medical problem that requires treatment.

    That calls for an intervention. A helper shoots the animal with a dart(飞镖). If the gorilla appears to have a serious but treatable illness, the dart contains antibiotics to fight off infection. If it appears to need surgery, the dart contains a drug that leaves the gorilla unconscious and unable to feel pain.

    Although the gorillas are critically endangered, there are signs of hope, thanks in part to Gorilla Doctors. The mountain gorilla is the only great-ape species whose population is growing.

    “Habituated mountain gorillas are increasing by 4% each year, which is as fast as the human population is growing globally,” Mike says. He notes a recent study that credits the work of Gorilla Doctors for 50% of that growth. He is proud of the role his team has played in making it happen.

    Here are some of the strangest aviation(航空)ideas in recent history.

    Double-Decker Seating

    In 2015, Airbus filed a patent for a design for a double-decker cabin seating arrangement. Passengers would sit on top of the other, with upper-tier passengers climbing steps or a small ladder to reach their seats. While the design does have some advantages, the idea of climbing a ladder during flight seems unreliable.

    Separated Cabins

    This patent was awarded to Airbus. Rather than waiting for a flight to arrive and be cleaned,passengers could simply board a ready cabin, which would be moved into the plane's body as soon as it was ready. When the plane reached its destination, the cabin would be separated again. Different cabins with different kinds of seating or levels of comfort could be used for flights of different lengths or destinations.

    Windowless Cockpits(驾驶舱)

    For ideal design, airplane noses should be long and pointy. But there's the whole "pilots have to fit in the cockpit" problem. Well, what if the cockpit didn't have to go in the nose of the plane? That's part of the thinking behind this Airbus patent application* which suggests replacing the plane's window with a digital viewing surface. Without a window, there's no reason the cockpit needs to go in the front of the plane —it could go in the middle of the plane, or even in the tail.

    Nap Straps (睡眠吊带)

    Airbus is not the only company in the strange patent contest. Boeing's got its own patent, Nap Straps. With this invention, passengers looking for a nap can find an "upright sleep system^" beneath their seat. In action, the whole thing is somewhat like a traction device for someone who's been in a terrible accident.

    It seems that electronic devices just keep getting smaller. Scientists in the United States have announced the creation of the first transistor with only two dimensions(二维).

    A transistor is a small electronic device that transfers or carries electronic current. Scientists hope these new 2D transistors will be used for building high-resolution(高分辨率)displays that need very little energy.

    Two groups of scientists created these 2D transistors. They report that the transistors are only a few atoms thick.

    Usually transistors are made with the element silicon(硅). Computer processors, memory chips, TV screens and other electronic devices contain billions of silicon-based transistors. But these very small electrical parts have certain limitations.

    Dimitris Ioannou is an electrical engineering professor at George Mason University. He says the traditional transistor has been improved as much as it can be. He adds that researchers have been looking for new materials with special features and they want transistors to be seen through and soft.

    "If the layers are very thin, the transistor can become flexible, so it doesn't have to be rigid(坚硬的), like it would be in a silicon chip. So people can think of applications like wearable electronics, television screens and other things," said Ioannou.

    These new transistors can also carry higher current. They also can move the current much faster than traditional transistors. This is important for high-definition screens.

    Dimitris Ioannou says the scientific success could prove very useful in the future. "Now, how good and how useful it will be, it's still in the stage of research, but it certainly is an advance," said Ioannou.
