    Engineers at the University of California San Diego have developed a new method that doesn't require any special equipment and works in just minutes to create soft, flexible, 3D-prnted robots.

    The innovation comes from rethinking the way soft robots are built: instead of figuring out how to add soft materials to a rigid robot body, the UC San Diego researcher started with a soft body and added rigid features to key components. The strictures were inspired by insect exoskeletons, which have both soft and rigid parts — the researchers called their creations

    “flexoskeletons (柔性外骨骼)”.The new method allows for the construction of soft components for robots in a small bit of the time previously needed and for a small bit of the cost.

    “We hope that these flexoskeletons will lead to the creation of a new class of soft robots, ” said Nick Gravish, a mechanical engineering professor at the Jacobs School of Engineering at the UC San Diego and the paper's senior author. “We want to make soft robots easier to build for researchers all over the world.”

    The new method makes it possible to build large groups of flexoskeleton robots with little hand assembly (装配)as well as assemble a library of Lego-like components so that robot parts can be easily swapped.

    Researchers detail their work in the April 7 issue of the journal Soft Robotics. The team plans to make their designs available to researchers at other institutions as well as high schools.

    One flexoskeleton component takes 10 minutes to print and costs less than $1. Flexokeleton printing can be done on most low-cost commercially available printers. Printing and assembling a whole robot takes under two hours.

    The final goal is to create an assembly line that prints whole flexoskeleton robots without any need for hand assembly. These small robots could do as much work as one massive robot on its own — or more.

    The deadliest Ebola outbreak in history that has so far killed almost 1000 people in Guinea, Liberia, Sierra Leone and Nigeria in West Africa has caused fear around the world.

    The outbreak is unprecedented(空前的)both in infection numbers and in geographic scope. Officials from the World Health Organization (WHO) said earlier this month the outbreak “is moving faster than our efforts to control it”, reported CNN. So far, the battle against the virus doesn't appear to be slowing down.

    The Ebola virus is terrifying no matter where it strikes: It's a disease with no cure that causes headaches and fever, severe diarrhea(腹泻), vomiting and bleeding and has been known to kill up to 90 percent of its victims.

    It is understandable for people to be panicked, but those living outside Africa shouldn't be particularly concerned about contracting the virus, says a Washington Post article.

    This is because transmission of Ebola requires direct contact with an infected person's blood, vomit or other bodily fluids during the period that he or she is contagious(接触传染的). It is something that is extremely unlikely for anyone but healthcare workers. The virus is not spread by coughing or sneezing.

    Media outlets in the US and the UK are using terrifying headlines, wrongly claiming that people infected with the virus have traveled to their countries.

    James Ball at The Guardian says the Ebola outbreak in Africa is tragic, but it is important to keep a sense of proportion. Other infectious diseases, including common influenza, are far, far deadlier.

    If you've not heard that the decade-old princess-culture is causing problems—especially if you're a parent—you must be actively working to avoid it.

    The latest study adding fuel to the fire comes out of Brigham Young University and finds that the Disney princess obsession can be harmful to girls.

"I think parents think that the Disney princess culture is safe. That's the word I hear time and time again—it's safe." Lead study author Sarah M. Coyne of the Mormon institution in Utah noted in a press release. "But if we're fully jumping in here and really embracing (accepting) it, parents should really consider the long-term impact of the princess culture."

    So, what's the problem this time around? Same as always, confirmed the study, published in the journal Child Development, which involved the assessment of 198 preschoolers: Lots of engagement with princess culture (whether through moves or toys) can lead to gender-stereotypical(性别定性) behavior as well as self-critical body image.

The strict gender stereotypes can hold girls back. "They feel like they can't do some things," Coyne said, "They're not as confident that they can do well in math and science. They don't like getting dirty, so they're less likely to try and experiment with things."

On the other hand, "Disney princesses represent some of the first examples of exposure to the thin ideal," Coyne said. "As women, we get it our whole lives, and it really does start at the Disney princess level, at age 3 and 4."

So, what should a parent do? Try his or her best to avoid all princesses for the entire of a girl's childhood? I'd say, have moderation in all things, have your kids involved in all sorts of activities, and just have princesses be one of many, many things that they like to do and engage with." Coyne suggested. "This study has changed the way I talk to my daughter, the things I focus on, and it's been really good for me as a parent to learn from this study," Coyne said. "I usually can't say that my research findings have such a personal impact on my life."

    As they migrate(迁移), butterflies and moths(飞蛾) choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind.

    Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect such little creatures at such great heights.

    To their surprise, though, the insects weren't passive but active travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate(导航) directly to their wintering homes.

    Even in the spring, when most winds flowed northward, the insects didn't always go with the flow. If breezes weren't blowing in the exact direction they wanted to go, the insects changed their body positions to compensate(抵消). Many migrating birds do the same thing.

    The study also found butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications.

    With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help when farmers decide when to spray their crops.

    Camping is a good way to spend time along with your kids and to show them how wonderful nature can be. Through camping, children can discover new things about nature, such as flowers, birds, and other small animals. Camping gives kids time to get away from all the electronics (电子) of today's culture. So it is necessary to plan exciting and enjoyable family camping trips with your children while they are young.

    When planning your family camping trip, consider the activities your kids like: games, hiking, swimming, boating, bicycling, etc. Select a camping place that has some of the activities the kids are interested in. Meal planning is an important part of your camping trip. Plan the meals together, and kids love to choose what they want to eat.

    When starting to pack for your trip, let the kids pack their own items (物品) . Each person should have his/her own sleeping bag with a luggage (行李) bag to put it in. Personal items should be packed with their sleeping bags. Encourage the kids to put their items in a certain place and always return it when they have finished using it.

    When you have arrived at your campsite, make all the camping activities a family activity, which will help children to realize how important team-work is. Everyone can have his/her own job sitting up the campsite. Meal time can be a fun time. So let the older ones help with the cooking on your outdoor camping stove while the younger ones get the picnic table ready.

    A couple had a son eleven years after they married. They were a loving couple and the boy was the apple of their eye. When the boy was around four years old, one day the father was very tired after work so he asked his wife to pick up their son. The mother, who was very busy in the kitchen, totally forgot about it.

    Later the boy lost his way on the street. When the son was found missing, the mother hurried to look for him, but she didn't find him. The mother felt very sad and didn't know how to face her husband.

    When the father went to the police station after hearing that the son was missing, he looked at his wife and said just four words. What do you think the four words were? The husband just said "I love you, darling."

    The son was missing. If he had picked him up earlier, this would not have happened. There is no point in blaming (责备) anyone. His wife had also lost her only child. What his wife needed at that moment was comfort and understanding from her husband. That is what the husband gave his wife. Several weeks later, with the help of the police, the couple finally found their lost son. The family's relationship became stronger over that time.

    Sometimes we spend lots of time asking who is to blame. We miss many chances to give each other support and let each other feel the warmth of human relationships. Get rid of all your unwillingness to forgive, selfishness, and fears and you will find the world is much more wonderful.

    I was in Walt Disney World with my son, Daniel, who is autistic (患自闭症的), and at that time he was 7 years old. My wife and our three other sons were with us too. He was having one of his melt down screaming tantrums (发怒), only God knows why. So my wife and I decided I would take the bus back to the hotel, and she would stay in the park with the other three children.

After we got on the bus, the screaming continued. My son looks "normal". To the many people on the bus, he appeared to just be a kid screaming — or a spoiled child who did not get his special toy that day. It did not take long — less than a minute — before the screaming brought about stares, then glares from the other passengers.

    To my shame, I found myself losing my temper at my own son. I was embarrassed, angry, and frustrated, and felt cheated by God for not being able to enjoy a normal vacation with my family because of him. I started to wonder what life would be like without having to deal with this cross (痛苦).

    And just as the reactions of the other passengers were becoming most intense, a man seated just in front of me turned around to face me. I cheered myself up for his advice on how to raise a well-behaved child.

    He said calmly, "Is he alright?" I said, "He's autistic." Then the man said, "It's alright." And he smiled. That's all.

    And suddenly, all the anger building up inside me was gone. I almost wept for shame at how I had felt a moment before. It no longer mattered what the other people thought. My son was my gift from God.

    I will never forget that man, nor his small, simple act of kindness and understanding. I truly believe he was my son's guardian angel that day maybe mine too.
