1 . While going to the aquarium（水族馆）is a great way to learn about sea animals, some have raised concerns about the animals' quality of life. But Edge Innovations, a company in New Zealand, has a very special way to solve the problem.

Edge Innovations is working with American creators of some of Hollywood's most famous animals to develop robot dolphins that look like almost exactly the same as real-life animals.

The ocean park industry has had falling interests for over ten years because of ethical（道德的）concerns and the cost of live animals, yet people's hunger for learning about and experiencing these animals is still as strong as ever. Developers believe that it's time to make a change in this industry and that this method shows humans' mercy and brings more interests at the same time.

One robot dolphin could cost an aquarium at least $ 26.3 million. But the robot would be controlled by humans and be able to play with humans as a regular dolphin would. The price at the moment is very high, but Edge Innovations notes that since the robots last longer than a real animal, the returns will be worth the price.

The robot dolphin weighs just about 600 pounds but is amazingly life-like. According to The Guardian, a test audience was actually not able to tell it apart from a real dolphin. As for aquarium visitors, the developers forecast that they won't mind not seeing a "real" dolphin. "For people in New Zealand, for me, I prefer natural animals," said Li Wang, the business developer for Edge Innovations. "But when we think about the new generation who spend far more time than us playing electronic games online, we think the robot dolphins will be accepted.”

The development of robot animals may be the future of zoos and aquariums, making it easier for animal lovers to enjoy nature in a kind way.

2 . A mother has taken her celebration（颂扬）of great women in history to the next level—by dressing her baby daughter up as some of the most famous women of all time. Jenelle Wexler, a hair stylist from Chicago, the USA, came up with the idea when she noticed similarities in appearance between her four-month-old baby, Liberty, and a Mexican artist Frida Kahlo.

Wexler took photos of Liberty who was dressed up as the Mexican artist. And after that, Wexler wanted to go on with what she did. "The pictures came out wonderfully, and soon after that, I thought about other women in history that contributed to the benefit of women and people as a whole," she says.

Wexler takes the photos with her iphone. Up until now, she has dressed Liberty up as a series of famous women, including Marie Curie, Coco Chanel, Madonna and Amelia Earhart.

Once she decides which woman she would like Liberty to play, she researches the person and learns about some of the historic achievements this woman has made. Wexler checks photos of each woman, which she then uses to design clothing and setting that will show their character and achievements.

It takes Wexler around 20 minutes to take each photo, and for every dress-up activity, Wexler usually takes nearly 50 pictures in total. "Liberty has acted 34 women of influence," she says. She just wants to draw people's attention to those who should really be admired in our society—there are so many great women who need to be remembered and have their stories told.

5 . While it's not impossible for birds to fly in the rain, they usually choose not to. You may see birds fly for a few seconds in poor weather, but most of them prefer to stay put on rainy days.

Why does rain make it harder for birds to fly? You might imagine that moving through the air while being pelted by raindrops would be pretty unpleasant. However, it's not the rain itself that makes flying difficult. Instead, birds are influenced by the drop in the air pressure that comes with most rainstorms. When pressure drops, the air is less thick, which makes it harder for birds to fly. Moving through the sky in areas of low air pressure takes a lot of energy.

Most birds need to eat several times a day—rain or no rain. Luckily, most birds' feathers（羽毛）are highly waterproof（防水的）, protecting the skin beneath. Many birds can also make oil that they can spread over their feathers to further protect themselves from the rain. Most birds don't like rain. In fact, in a 2010 study, a team of researchers studied birds living in a Costa Rican rainforest. They found that the birds had higher levels of stress hormone（应激激素）on rainy days. That may not surprise you. After all, many animals feel stressed out during storms. Pet owners often find that rain and thunder make their animals nervous. Some animals are so strongly influenced by nature that they almost seem to forecast the future.

No one really knows how many birds die during a storm or series of storms. But the number is certainly higher than usual. They fly into trees or windows; they get lost over the ocean or a large lake; their food sources are made more difficult to get but, at the same time, they need more food to get warm. However, if rain continues for some time, birds will have to challenge the storm.
