Happy Cow app

Vegetarians do not eat animal meat. Vegans do not eat any animal products. The Happy Cow app is made for both groups. Users can search for vegetarian-vegan restaurants and stores around the world.

Local Eats app

Restaurant chains, like McDonalds, can be found almost anywhere a person might travel. But sometimes travelers want to eat like locals. The Local Eats app is designed for that. It can help you find local restaurants in major cities in the US and in other countries. It costs about a dollar.

Where Chefs Eat app

“Where Chefs Eat” is a 975 page book. Most people would not want to carry that around. But there is a much lighter app version of the same name for just $ 15. Six hundred chefs provide information on 3, 000 restaurants around the world on the Where Chefs Eat app.

Students at an elementary school in California, with the help of their art teacher, created a telephone hotline that people can call to get cheerful advice from kids during difficult times. In just days, the hotline began getting thousands of calls an hour.

The hotline is available in English and Spanish. It offers the happy voices of children of different ages sharing positive messages. For example, by pressing 3, you can hear a group of kindergartners saying together:“You can do it! Keep trying, don’t give up!” Pressing 4 triggers the sounds of children giggling and laughing—a sound certain to bring a smile to anyone’s face.

Jessica Martin, who teaches art at West Side School in Healdsburg, California, thought her students just might have the magic words needed to bring calm to people in difficult times. ”To hear the pure joy from kids is extremely comfortingshe says.

Students working on the hotline should first think of what they would like to say to encourage someone else. When they were ready, Ms. Martin recorded each one. Later, she sorted out the recordings into the different parts of the telephone hotline. Pressing 1 brings up ideas for people who are “feeling mad, frustrated, or nervous“. Helpful suggestions include: ”punch your pillow“, “jump on the trampoline”, or ”go get a cookie“. Pressing 2 results in “words of encouragement and life advice”, which includes messages like: ”The world is a better place with you in it.“ And “You are okay!”

Words of the hotline spread quickly on social media. The hotline has become incredibly popular with stressed adults, patients in hospitals, older people in homes_, and others who just want to hear the happy voices of children.

Do you like the woolly mammoths (毛猛犸象) from the movie Ice Age? Too bad they’re extinct? Thanks to recent developments in biotechnology, the stuff of science fiction may soon become a reality through an attractive process called “de-extinction”, which aims to bring the extinct species back. The resurrected (复活的) species are functionally equal to the original extinct species, but they are not exact copies.

There are three primary techniques of de-extinction. One of them is that scientists deliberately select existing species with similar characters to the extinct species to produce later generation. This is a natural method. Another is cloning. A cloned animal is created by obtaining the DNA of the extinct animal. The later generation will be an identical copy of the extinct species. This is only applied to animals that are either endangered or have recently gone extinct, as it requires well-preserved eggs. The third is the newest technique, genetic engineering (基因工程). It uses gene-editing tools to place selected genes from extinct animals in place of those present in its closest living relative.

If we refer to Jurassic Park, resurrecting extinct animals is a terrible idea. Thankfully, we don’t have to worry about dinosaurs running wildly, as their DNA has disintegrated over the 65 million years since their extinction. DNA can survive for several million years at best under certain rare conditions, but does that mean we should do that?

De-extinction is more for ecology than for tourism. Ecologist Ben Novak said, “All animals perform critical roles in their ecosystem. Woolly mammoths, for example, were excellent gardeners. Their disappearance was followed by a loss in diversity and the Arctic grassland became a cold, ice field. If a resurrected animal is always going to be a zoo animal then it shouldn’t be brought back.”
