A European Union program is letting blind people experience famous paintings for the first time. It uses three dimensional(3-D) printing to re-create famous paintings so they can be touched.

    One painting printed with the new technology is Gustav Klimt's “The Kiss.” It is a popular attraction at the Belvedere Museum in Vienna, Austria. The painting shows a man and a woman standing in a field filled with flowers. They are wearing gold robes and have their arms around each other. The man leans down to kiss the woman.

    Klimt finished the painting in 1908. Until now, people who had trouble seeing could not appreciate the artwork. But thanks to the reproduction they can touch the piece and feel the ridges and depressions. Andreas Reichinger started making 3-D versions of artwork in 2010. He said this reproduction was his most difficult project because the couple's robes are so detailed.

    Dominika Raditsch is a blind museum visitor. She touched the reproduction. As she moved her hands around it she said, “Exactly, can you see these? There are so many details.” Raditsch said she can imagine what the original painting looks like when she touches the reproduction. “It's somehow round. You can feel it. You can feel it. It comes with it. And in many places it's so smooth. And then I think to myself: it probably shines too!” Raditsch said.

    The Belvedere is not the only museum to have 3-D versions of its artwork. Some of the pieces at the Prado, in Madrid, Spain, have reproductions that can be touched. But the piece in Vienna has one special part: It is made with widely available 3-D printing technology. That means one day, blind art fans anywhere in the world could download the source files and print the reproductions themselves.

    PhoneSoap: Charge and Clean Your Phone

    You may charge your phone every day, but do you clean your phone as much? Whatever your hands touch, your phones touch. It has been discovered that some phones have 18 times more bacteria and viruses than any surface in a public restroom. So it probably won't surprise you that a 2011 University of London study found that one in six of our phones have bacteria and viruses on them—specifically, the bacteria called E. coli.

    The research on bacteria and viruses led to the invention of PhoneSoap. It is not actually liquid like dishwasher soap. It is a phone charger that uses the electromagnetic radiation (辐射) used in hospitals to kill 99.9 percent of bacteria and viruses, cleaning your phone while it charges.

    “There are really certain types of bacteria and viruses that we should not be in touch with, and they are really on our phones,” says Wes Barnes, the PhoneSoap co-founder. It all started while his cousin and co-founder, Dan LaPorte, was in his cancer research lab at college. “He realized he got the idea of getting rid of bacteria and viruses on the phones,” said Barnes. “In the lab they used UV-C light for destroying them. He realized this would be the fastest, most powerful way to kill any bacteria and viruses living on electronic machines.”

    PhoneSoap looks like a little metal suitcase. Your phone rests in to charge and get cleaned at the same time. Instead of plugging your phone into the wall, you'd plug it into the PhoneSoap charger box. The process only takes a few minutes but, Barnes says, “The idea is that you can leave it in there overnight if you want to keep charging. Reflective paint keeps the light completely around the phone so it cleans the phone fully.”

    The co-founders spent 2013 finding the right companies and they started shipping the product in late November. By last week's International Consumer Electronics Show in Las Vegas, PhoneSoap was all grown-up. Both co-founders have left their previous jobs and are selling PhoneSoap nonstop. “We're shipping almost more than we can handle each day,” Barnes says. “It's been a great adventure.”

Dear Aunt Tara,

    I have a problem with my homework. We have to do it in a group. It has to be finished this Friday, but Gary, the boy in our group, has done nothing helpful. He just keeps rocking the boat.

    Every time we talk about the work with him, he always "Don't worry. I'll do it later" But he seldom does his job. And when he does it be the wrong way. Someone has to do it for him again what's is when Mas Lin asks about our group, Gary always tell her that we others don't work hard enough I'm really mad at Gary about this. We're in the same group. Shouldn't we help each other to do a better job?

Kate

Dear Kate

    It is important or students to learn how to work together in a group. Maybe you should talk to Gary about the problem and tell him you all need his help. If he still doesn't changes, go to talk to your teacher. I believe she can make Gary do his job.

Aunt Tara

    Life is difficult.

    What do you think about life? Maybe most people say that life is difficult. But life is no longer difficult once we truly understand and accept it. Most people do not fully see this truth. Instead, they complain about their problems and difficulties as if life should be easy. It seems to them that their difficulties represent a special kind of suffering especially forced upon (强加于) them or their families, their class, or even their nation.

    What makes life difficult is that the process of facing and solving problems is a painful one. Problems, depending on their nature, cause us sadness or loneliness or regret or anger or fear. These are uncomfortable feelings, often as painful as any kind of physical pain. And since life causes an endless series of problems, life is always difficult and is full of pain as well as joy.

    Yet, it is in this whole process of solving problems that life has its meaning.

    Problems are the serious test that tells success from failure. When we desire to encourage the growth of the human spirit, we encourage the human ability to solve problems, just as in school we set problems for our children to solve. It is through the pain of meeting and working out problems that we learn. As Benjamin Franklin said, "Those things that hurt instruct." It is for this reason that wise people learn not to fear but to welcome the pain of problems.

A researching team analyzed data from long-running studies conducted in Brazil and South Africa to assess whether children exposed to early adversities (逆境), such as extreme poverty, low birth weight, and pre-term birth, could reach their full learning potential by experiencing responsive caregiving and opportunities to learn in their home. They found that early life adversities matter throughout life. Teenagers who had been exposed to multiple adversities early in life had lower IQ scores, were more likely to have difficulties adjusting socially and psychologically, and achieved a lower physical height compared to teenagers exposed to fewer adversities. They also found that being raised in a nurturing (培育) environment could significantly counteract the negative effect of early adversities on IQ and help children achieve their full potential of intelligence.

Globally, more than 250 million children younger than 5 years are at risk of not reaching their developmental potential because of adversities that co-occur early in life and worsen with age. In the US, almost one in five children are raised in poverty and 15 percent do not complete high school. Exposing these children to a nurturing environment, whether at home or in daycare or pre-school settings, can lead to cognitive (认知的) benefits that last into teenage and beyond.

Parents should provide nurturing environments, which include interacting with young children in a positive way such as reading children's books from the library, singing songs together, and playing games with numbers and letters. Children who join in age-matched housework like picking up toys and clearing the table gain skills and feel good about helping. Get children involved in friendly activities as much as possible rather than park them in front of a screen. Children love to learn and in a nurturing environment, they can grow into teenagers and adults with the abilities to care for themselves, their families, and their communities.

According to a new research,the more people in a country who have a particular gene(基因),the happier the nation will be.This DNA is known as the FAAH gene.People with a particular version of it tend to be cheerier souls.There is a link between levels of the FAAH gene and the number of people who say they are very happy.

Sweden—one of the happiest countries in the world—also has lots of happy DNA.Ghana,Nigeria,Mexico and Columbia all come out near the top in the happiness league,and have high rates of the gene.In contrast,the people of Iraq,Jordan and China are among the least likely to rate themselves as very happy and also have the lowest level of the FAAH gene.

However,wealth and health are found to have little effect on happiness.The finding could help explain why some of the world's poorest nations are also the happiest.In addition,the FAAH gene and an optimistic attitude would not always go hand in hand.For example,Russians and Estonians score very low in happiness,despite having the right happy DNA.

Professor Michael Minkov said,"The climate condition is associated with the nation's happiness.We can notice the high occurrence of the FAAH gene in tropical(热带的) areas in the Americas and Africa.And the occurrence of the gene around the Mediterranean Sea is much lower than that in Northern Europe."

The social experts say that genetics is not the only determinant(决定因素) of happiness.The economic and political difficulties in some nations also contribute to the very low happiness scores.Nations that are not blessed with the right DNA aren't necessarily miserable.
