Studies show that you may be lied to every day anywhere from 10 to 200 times. We say, “Nice song.” “Honey, you don't look fat in that, no.” But another study showed that strangers lied three times within the first 10 minutes of meeting each other. We lie more to strangers than we lie to coworkers. Men lie eight times more about themselves than they do about other people. Women lie more to protect other people. If you're married, you're going to lie to your wife/ husband in one out of every 10 communications. If you're unmarried, that number drops to three. But look, if at some point you got lied to, it's because you agreed to get lied to. Truth about lying: lying's a cooperative act. Not all lies are harmful. Sometimes we're willing to get lied to for social dignity(尊严), maybe to keep a private secret.

    Lying is complex. It exists in our daily and business lives. We're deeply disturbed by the truth. We explain it, sometimes for very good reasons, other times just because we don't understand the gaps between ideals and realities in our lives. We're against lying, but secretly we're for it in ways that our society has practiced for centuries and centuries. It's as old as breathing. It's part of our culture and history. Think the stories from Dante, Shakespeare, the Bible, News of the World.

    Lying has great value to the evolution of human beings. Researchers have long known that the more intelligent the species, the more likely it is to lie. We humans like to become leaders. It starts really early. How early? Well, babies will pretend to cry, pause, wait to see who's coming and then go right back to crying. One-year-olds learn hiding truth. Five-year-olds lie outright and try to control through flattery (奉承). Nine-year-olds, masters of covering up.

    So what do we do about lies? Well, there are steps we can take to guide our way through the bushes. Trained lie spotters (检测员) get to the truth 90% of the time. The rest of us, we're only 54% right. There are clever liars and stupid liars, but there're no real creative liars. While lying, we all make the same mistakes, and we all use the same techniques.

    The latest study by the University of Florida has found that eating from smaller, less beautiful, and even paper plates will help prevent overeating. Eating with a fork instead of a spoon can help you lose weight, the researchers say. Much to their surprise, they find that putting mirrors in the dining room will also help reduce weight.

    The researchers asked 185 college students to choose a chocolate cake or a fruit salad, and evaluated the taste. Those who ate in a room with a mirror scored the taste of junk food much lower than those in a room without a mirror. But the taste of fruit salad remained the same in any case.

    Lead scientist, Dr. Ata Jami, says that a glance in the mirror tells people more than just about their physical appearance. It enables them to view themselves objectively and helps them to judge themselves and their behavior in the same way that they judge other people.

    The mirrors were found to push people to compare and match their own behavior with accepted social standards. The researchers believe it proves that people don't want to look in the mirror when they feel they are following the social standards. When they look in the mirror with mouths full of junk food, feelings of discomfort and failure can be increased. Therefore, the presence of the mirror lowers the taste of unhealthy food.

    However, researchers say this is only the case if people select the food they are eating, because they are responsible for that choice. The researchers suggest that mirrors be placed in dining rooms and other eating spaces, so that people will start eating more healthily.

    A project in Gambia is empowering women and reducing dangerous waste at the same time.

    The Waste Innovation Center, funded by the European Union's Global Climate Change Alliance, shows women in the Brikama area how to recycle waste into useful materials and products, which they can then sell in local markets.

    Wood-like waste is recycled into charcoal (木炭), for example, which can be used to supersede firewood and reduce the number of trees that are cut down for firewood. Food waste is recycled into compost(混合肥料)to function as environmentally friendly fertilizers and plastic is turned into many useful things.

    Supported by Waste Aid UK and the Gambia Women's Initiative (GWI), among others, the project provides women with skills they can use to become self-sufficient (自给自足的). Women learning at the center come from five communities, and some of them travel as far as 12 miles to learn these important skills that will provide them with an income, according to The Guardian.

    Isatou Ceesay, who now leads the GWI, highlighted the need to focus on economic equality in her country, telling The Guardian, "In terms of education, women are the ones who are always behind. Boys are chosen to go to school. When we conduct our training, we find women can do a lot, but don't know who they are, or how to carry out things. "

    According to the World Health Organization's Country Cooperation Strategy 2018—2023 report, the main environmental issue facing Gambia is poor waste management in urban areas. Ndey Sireng Bakurin, executive director of the National Environment Agency, has voiced concern over health and environmental risks, such as water pollution, the increase of insects as well as flooding that occur as a result of poor waste management.

    With existing medical knowledge and skills, two-thirds of the world's 42 million, blind should not have to suffer. Unfortunately, rich countries possess most of this knowledge, while developing countries do not.

    ORBIS is an international non-profit organization which operates the world's only flying teaching eye hospital. ORBIS intends to help fight blindness worldwide. Inside a DC-8 aircraft, there is a fully-equipped teaching hospital with television studio and classroom. Doctors are taught the latest techniques of bringing sight back to people there. Project ORBIS also aims at promoting peaceful cooperation among countries.

    ORBIS tries to help developing countries by providing training during three-week medical programs. ORBIS has taught sight-saving techniques to over 3,000 doctors and nurses, who continue to cure tens of thousands of blind people every year. ORBIS has conducted 17 plan programs in China so far. For the seven to ten million blind in China ORBIS is planning to do more for them. At the moment an ORBIS is working on a long-term plan to develop a training center and to provide eye care service to Shanxi Province. ORBIS needs your help to continue their work and free people from blindness.

    For just US$38, you can help one person see; for $380 you can bring sight to 10 people; $1,300 helps teach a doctor new skills; and for $13,000 you can provide a training program for a group of doctors who can make thousands of blind people see again. Your money can open their eyes to the world. Please help ORBIS improve the quality of life for so many people less fortunate than ourselves.

    Sweet potato plants don't have spines or poisons to defend themselves. But some have evolved a clever way to let hungry herbivores (食草动物) know they aren't an all-you-can-eat buffet, a new study finds. When one leaf injured, it produces a chemical that warms the rest of the plant and its neighbors to make themselves inedible (不宜食用的)to bugs. Sweet potato breeders could potentially engineer plants to produce the chemical as an all-natural pest defense.

    Plant ecologists led by Axel Mithofer of the Max Planck Institute for Chemical Ecology in Jena, Germany, started to look into sweet potato (Ipomoea batatas) defenses after they noticed something interesting about two varieties of the plant grown in Taiwan: The yellow-skinned, yellow-fleshed Tainong 57 is generally herbivore-resistant, but its darker orange cousin, Tainong 66, is plagued (造成麻烦) by insect pests.

    To find out why, the team offered up Tainong 57 and 66 plants to hungry African cotton leafworm caterpillars (毛虫).Both plants released at least 40 airborne compounds as the caterpillars snacked on their leaves. But Tainong 57 produced a lot more of a chemical called DMNT, which has a very distinct smell, the team details this month in Scientific Reports. ("The smell is not nice," Mithofer says. "You wouldn't want it as a perfume.")

    DMNT isn't a new compound; researchers have isolated (分离出) the smelly chemical from other plants such as corn and cabbage, and it is known to induce defense responses in some species.

    To determine whether this was happening in sweet potatoes, scientists set up two experiments. First, they put two plants next to each other and wounded one so it produced DMNT. Then, they exposed healthy Tainong 57 plants to DMNT they had synthesized (合成).In both cases, the DMNT caused the exposed plants to produce more of a protein called sporamin in their leaves. (Tainong 66 did not have the same reaction.) When the caterpillar's snack on sporamin, "they immediately stop eating because they don't feel well," Mithofer says.

    Sporamin is the main protein in sweet potato tubers (块茎),and is indigestible raw, which is why sweet potatoes must be cooked for humans to enjoy them. "If the caterpillars could cook it, they could eat it," Mithofer says. Theoretically, he says, sweet potato breeders could use genetic engineering to make different varieties of sweet potato produce as much DMNT as Tainong 57, and display the same defense responses.

    Still, the research isn't ready for prime time, cautions plant ecologist Martin Heil. DMNT might work in the lab, but in the field, airborne chemicals can be "blown away in seconds," says Heil, who studies plant-insect interactions at the National Polytechnic Institute in Irapuato, Mexico.

    Mithofer himself has no plans now to create genetically engineered sweet potato plants, because they would not be a viable (能活下去的) crop in Europe, where genetically modified crops are outlawed. So for now, Tainong 66 will have to put up with being a caterpillar salad bar.
