Geraniums of Love

    As the fifth of seven children, I went to the same public school as my three elder sisters and brother. Every year, my mother went to the same ceremony and had parent-child interviews（亲子交流会）with the same teachers. The only thing different was the child. And every child 1 an old

    Geraniums school tradition—the annual plant sale（拍卖会）held in early May, just in time for 2 Day.

    Third grade was the first time that I was allowed to take part in the plant sale. I wanted to surprise my mother. 3, I didn't have any money. I went to my eldest sister and 4 the secret, and she gave me some money. When I arrived at the plant sale, I carefully made my 5.

I was very afraid my mother would find it before Mother's Day, but my sister assured me that she wouldn't, and 8 she did not.

    When Mother's Day arrived, I was bursting with pride when I gave her that geranium. I remember how bright her eyes were, and how delighted she was with my 9.

    The year I was fifteen, my younger sister reached third grade. In early May, she came to me full of wonder and secrecy and told me that there was going to be a plant sale at school and she wanted to 10 our mother.

    I helped my little 15 hide that geranium on the upstairs neighbor's porch, assuring that our mother wouldn't find it before Mother's Day.

    Losing a wallet is one of those careless acts most of us have come across, at some point or the other in our lives. While most of us tend to move on after mourning over the lost necessities, there are a few lucky ones who get them back, with the help of the police or the generosity of the person who finds it.

    And then there is Hunter Shamatt, who not only got back his wallet but with some added happiness that was tagged along!

    Hunter was on his way to attend his sister's wedding on a Las Vegas-bound flight when he realized that he has misplaced his wallet, sometime during the journey. Hunter's family reached out to the Frontier flight to enquire if someone had handed it over to them. Unfortunately, there was no sign of the missing wallet.

    But wait. The story was far from over. Just a week after Hunter's sister's wedding, he received a package in his mail. And guess what? There was his wallet! Surprisingly, the wallet was not the only thing that was inside the package. It also had a handwritten note for Hunter which turned out to be a bonus! The piece of paper read,

"Hunter, Found this on a Frontier flight from Omaha to Denver — row 12, seat F wedged between the seat and wall. Thought you might want it back. All the best.

P.S. I rounded your cash up to an even $100, so you could celebrate getting your wallet back. HAVE FUN!!!"

    Moved by the touching gesture, Hunter's mom, Jeannie Shamatt, decided to write a post on Facebook giving a detailed description of the incident. She also urged everyone to share the post as she would like to meet and greet the person behind the act of kindness, personally.

    Now, thanks to the astonishing power of social media, the post finally reached the man behind the note. The man was identified as Todd Brown and it was one of his co-workers who made sure Jeannie Shamatt's post reaches his colleague. Jeannie turned to Facebook again to thank Brown and his family for restoring her faith in humanity.

    "I try to teach my children to do the right things in life, help people when you can regardless of the outcome. This story is more about restoring faith in people than anything. We hear a lot of bad news but not enough good news. I personally want to thank Todd Brown and his wife for restoring faith that there are amazing people out there."

Learning New Vocabulary during Deep Sleep

    Sleeping time is sometimes considered unproductive time. This raises the question whether the time spent asleep could be used more productively, e.g. for learning a new language? Up-to-now sleep research focused on the stabilization and strengthening of memories that had been formed during wakefulness. However, learning during sleep has rarely been examined. There is enough evidence for wake-learned information undergoing a revision by replay in the sleeping brain. The replay during sleep strengthens the still weak memory and leaves the newly acquired information in the pre-existing store of knowledge.

    If re-play during sleep improves the storage of wake-learned information, then first-play, i.e. the initial processing of new information, should also be possible during sleep.

    The research group of Katharina Henke examined whether a sleeping person is able to form new semantic（语义的）associations between played foreign words and translation words during the brain cells' active states, the so-called "Up-states." It turned out to be that what they thought was reasonable. When we reach deep sleep stages, our brain cells progressively coordinate their activity. During deep sleep, the brain cells are commonly active for a brief period of time before they jointly enter into a state of brief inactivity. The active state is called "Up-state" and the inactive state "Down-state". The two states alternate（交替）about every half-second.

    New evidence for sleep-learning challenges current theories of sleep and theories of memory. The concept of sleep that we are separated from the physical environment is no longer reasonable. "It's false that complex learning be impossible during deep sleep," says Simon Ruch, co-first-author. "In how far and with what consequences deep sleep can be applied for the acquisition of new information will be a topic of research in upcoming years," says Katharina Henke.

    The research group of Katharina Henke is part of the Interfaculty Research Cooperation (IRC). Thirteen research groups in medicine, biology and psychology are part of the IRC. The aim of these research groups is to gain a better understanding of the mechanisms（原理）involved in sleep and consciousness.

The Secret to Happiness

    A new report makes it clear that when it comes to the life satisfaction of UK citizens, the ball is in the government's court. For some time, sensible people have been arguing that governments need to focus less on economic growth and more on the wellbeing（幸福）of citizens. Be careful what you wish for.

    In response to this demand, from 2011 David Cameron instructed the Office for National Statistics to gather data on people's self-reported happiness and life satisfaction. Little practical good has come from this so far, but a new report by George Bangham for the Resolution Foundation is one of the best attempts to make useful sense of the data. He concludes: "The best prospects for policymakers targeting future increases in national wellbeing lie in raising job quality, raising incomes, particularly at the lower end, and policies to improve security in the housing market."

    The age correlation（相关）turns out to be certainly linked to politics, despite the fact that no political party can make a difference to your date of birth. The happiness of pensioners is not just a function of their age, but of policy. On average, 70-year-old boomers today are the most affluent retirees in history, often owning their own homes and in receipt of generous pensions. People of 70 are not going to be as content in 30 or 40 years' time if they are unable to retire, don't own their homes and have small incomes.

    However, there is one respect in which teens and recent retirees are remarkably similar. Compared to other age groups, they tend to inhabit a sweet spot of having high degrees of freedom. The typical 16-year-old has new freedoms without ever having had any serious responsibilities. The typical 70-year-old, having experienced a lifetime of work and family duties, has a very different kind of freedom, one born from relief.

    Besides, it should not surprise us to find that people tend to be happier when they have fewer worries. But this, too, has important political implications. If the government is really interested in raising overall national happiness, it has to make sure as many citizens as possible feel secure in their health, their housing and their incomes. Different states' records in achieving this is one important reason why Nordic countries repeatedly score highly in international life satisfaction surveys and North America underperforms relative to its GDP.

    Whichever way you look at it, there is no escaping the conclusion that increasing wellbeing across society requires joined-up, long-term policy efforts. This is exactly what the Resolution Foundation recommends.

A Diet Without Enough Protein Can Cause Depression

    Depression is a condition so common, the World Health Organization (WHO) calls it "a leading cause of disability."

    Difficulty in falling asleep, loss of appetite, and loss of ability to concentrate are just a few of the other effects of depression. WHO estimates that worldwide, at any one time, 350 million people suffer from the condition. While life events such as the loss of a spouse or a job may create a happening of depression, many cases come from within and are not caused by a life event.

    Now scientists are working on a new aspect of cure: nutrition. The Indian Journal of Psychiartry reports that both before and during a happening of depression, those with the condition will show a "poor appetite…" Many cases of depression, if not most cases, affect those who don't eat properly.

    So what does protein have to do with all this? It all comes down to amino acids (氨基酸). Proteins are made up of amino acids, chemicals known as the "building blocks of life." There are 20 different amino acids.

    Both the human brain and nervous system use amino acids as a substance that creates a signal from one brain cell to another or one nerve cell to another, thus relaying information between the cells. What the final result then?

    Since amino acids make up protein, a diet which lacks in protein will cause weaker communication between the brain cells. This lessens the signal being sent from one brain cell to the next during a thought. This is why depression can often express itself as anger or aggression.

A. The ultimate effect is how we think.

B. Don't ruin your appetite by eating between meals.

C. Skipping meals itself can create a depressed mood.

D. A new research suggests that nutrition can lessen some of the risks of depression.

E. India is perhaps the world's leader in researching the connection between diet and depression.

F. Many of them are made by the human body, but nine others, the "essential" amino acids, must be eaten in one's diet.

G. The process can lead to twisted signals, which can not only lead to depression, but also, according to many scientists, aggression.
