    More than loo genes are related with increased risk of developing schizophrenia(精神分裂症),bipolar disorder (躁郁症)and alcoholism(酗酒),confirms a large study published in the recent issue of the British scientific journal Nature.

    The world's largest study into the genetic basis of mental illnesses was led by researchers from British universities,including University College London (UCL),Cardiff University and King's College London (KCL).

    Researchers believe that they are now much closer than before to understanding the complex biological causes, which make some people being at high risk of developing mental illnesses.They also believe that these findings could lead to new treatments.

    The researchers analyzed the DNA of about 37,000 patients with schizophrenia,bipolar disorder or alcoholism, and compared the smallest genetic changes to those found in about 113,000 healthy people.They then identified about 128 independent genetic variants(变体)at 108 locations on the human chromosomes(染色体)that contribute significantly to developing schizophrenia—83 of these sites have never before been linked to the illness,according to scientists.

    For example,people with the variant of the GRM3 gene,thought to be important in brain signaling,are around 2 to 3 times more likely to develop schizophrenia or alcohol dependence.The variant,which is found in approximately one in every 200 people,is also associated with a three times risk of developing bipolar disorder.

    "We could be looking at the next big drug target for treating mental illness,"Professor David Curtis from UCL, co-author of the paper,said."The work opens up new ways to prevent and treat mental illnesses by revealing the mechanisms involved in their development."

    I told my friend Graham that I often cycle two miles from my house to the town centre but unfortunately there is a big hill on the route. He replied, "You mean fortunately." He explained that I should be glad of the extra exercise that the hill provided.

    My attitude to the hill has now changed. I used to complain as I approached it but now I tell myself the following. This hill will exercise my heart and lungs. It will help me to lose weight and get fit. It will mean that I live longer. This hill is my friend. Finally I comfort myself with the thought of all those silly people who pay money to go to a gym and sit on stationery exercise bicycles when I can get the same value for free. I have a smile of satisfaction as I reach the top of the hill.

    Problems are there to be faced and overcome. We cannot achieve anything with an easy life. Helen Keller was the first deaf and blind person to gain a university degree. Her activism and writing proved inspirational. She wrote, "Character cannot be developed in ease. Only through experiences of suffering can the soul be strengthened, vision cleared, ambition inspired and success achieved."

    One of the main determinants of success in life is our attitude towards adversity (逆境). From time to time we all face hardships, problems, accidents and difficulties. Some are of our making but many are no fault of our own. While we cannot choose the adversity, we can choose our attitude towards it.

    Douglas Bader was 21 when in 1931 he had both legs cut off following a flying accident. He was determined to fly again and went on to become one of the leading flying aviators in the Battle of Britain with 22 aerial victories over the Germans. He was an inspiration to others during the war. He said, "Don't listen to anyone who tells you that you can't do this or that. That's nonsense. Make up your mind, you'll never use crutches (拐杖) or a stick, and then have a go at everything. Go to school, and join in all the games you can. Go anywhere you want to. But never, never let them persuade you that things are too difficult or impossible."

    The biographies (传记) of great people are full of examples of how they took steps to overcome the difficulties they faced. The common thread is that they did not become depressed. They chose their attitude. They chose to be positive. They took on the challenge. They won.

    Nevertheless, there is still the problem of how you change your attitude towards adversity.

    We took a rare family road trip to the Adirondacks in late August,and it was as refreshing and exhausting as family vacations tend to be.Toward the end of our long drive home, even the kids were leaning forward in their seats urging my lead foot on.At that point in a road trip,even sixty-five miles per hour feels slow. We have become numb to our speed and numb to the road signs flashing by.

    My family lives on the edge of Lancaster County. Only thirty miles from home,I hit the brakes,and we began to roll,slowly,behind a horse-drawn carriage. We began to open our eyes again.We saw familiar green hills and the farm with the best watermelons. I rolled down the windows, and we breathed again.Just-cut hay and a barn full of dairy cattle.

    At five miles per hour,you remember what you forget at sixty-five.You are thinking about a place,even when you are moving from place to place.

    I am a placemaker. A homemaker, too. I am a mother of a young kid at home,and also a writer and a gardener.But,for me,those roles are wrapped up with the one big thing I want to do with the rest of my life:I want to cultivate a place and share it with others.

    The place I make with my family is a red-brick farmhouse built in l880. It has quite a few nineteenth-century bedrooms and a few acres of land,and we love nothing more than to fill them with neighbors and friends. We grow vegetables and flowers,keep a baker's dozen of egg—laying chickens,and,since we moved in three years ago,we have planted many,many trees.

    Living with my life's purpose does not allow for much travel. I need to be here,feeding the chickens and watering the tomatoes. Any extra in the budget,and we spend it on trees.

    But I learned something at the end of our family road trip.Travel can help me in the task of caring for my own place.When I slow down and pay attention to the road between here and there,travel tells me the connections between my place and all the other places.

    Modern inventions have speeded up people's loves amazingly. Motor-cars cover a hundred miles in little more than an hour, aircraft cross the world inside a day, while computers operate at lightning speed. Indeed, this love of speed seems never-ending. Every year motor-cars are produced which go even faster and each new computer boasts of saving precious seconds in handling tasks.

    All this saves time, but at a price. When we lose or gain half a day in speeding across the world in an air plane, our bodies tell us so. We get the uncomfortable feeling known as jetlag; our bodies feel that they have left behind on another time zone. Again, spending too long at computers results in painful wrists and fingers. Mobile phones also have their dangers, according to some scientists, too much use may transmit harmful radiation into our brains, a consequence we do not like to think about.

    However, what do we do with the time we have saved? Certainly not relax, or so it seems. We are so accustomed to constant activity that we find it difficult to sit and do nothing, or even just one thing at a time. Perhaps the days are long gone when we might listen quietly to a story on the radio, letting imagination take us into another world.

    There was a time when some people's lives were devoted simply to the cultivation of the land or the care of cattle. No Multi-tasking there; their lives went on at a much gentler pace, and in a familiar pattern. There is much that we might envy about a way of life like this. Yet before we do so, we must think of the hard tasks our ancestors faced, they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone, Modern machinery has freed people from that primitive existence.

    At a daycare center in Texas, children were playing outside. One of the children was Jessica Mc Clure. She was 18 months old. Her mother, who worked at the daycare center, was watching the children. Suddenly Jessica fell and disappeared. Jessica's mother screamed and ran to her.

    A well was in the yard of the center. The well was only eight inches across and a rock always covered it. But children had moved the rock. When Jessica fell, she fell right into the well.

    Jessica's mother reached inside the well, but she couldn't feel Jessica. She dialed 911 for help. Men from the fire department arrived. They discovered that Jessica was about 20 feet down in the well. For the next hour the men talked and planned Jessica's rescue.

    "We can't go down into the well," they said. "It's too narrow. So, we're going to drill a hole next to the well. Then we'll drill a tunnel across to Jessica. When we reach her, we'll bring her through the tunnel and up through our hole."

    The men began to drill the hole at 11 a.m. on Wednesday, October 14, 1987. The men had a difficult job; they were drilling through solid rock. During her days in the well, Jessica sometimes asked for her mother. Sometimes she slept, sometimes she cried and sometimes she sang.

    All over the world, people waited for news of Jessica. Everyone worried about her.

    At 8 p.m. on Friday, October 16, men reached Jessica and brought her up from the well. She was soon sent to hospital. Jessica was dirty, hungry, thirsty and tired. Her feet and forehead were badly injured. But Jessica was alive.

    After Jessica's rescue, one of the rescuers made a metal cover for the well, saying, "To Jessica, with love from all of us."

When it comes to commemorating a child's first year of life, the traditional approach often involves presenting an exquisitely adorned confectionery masterpiece to the young celebrant. By simply setting this visually striking sugar creation before the infant and activating the recording devices, one can capture the ensuing delightfully chaotic scene, replete with smiles and smears of frosting.

However, this will not be the method I choose to honor my daughter's initial 12 months of existence—not because the sweet treat will be absent, but because my spouse and I have resolved to abstain from sharing her images on social platforms for an entire year, and we are determined to maintain this practice for the foreseeable future.

I understand that I am part of a select few. Research indicates that approximately seventy-five percent of parents habitually upload photographs of their offspring to the internet. Pixsy, a platform that assists photographers in identifying unauthorized usage of their work, discovered that parents in the age bracket of 20 to 25 are twice as likely as their older counterparts to disseminate images of their little ones on social media platforms.

Yet, I am not the only one who feels this way. A woman instrumental in the creation of Big Little Feelings—an Instagram account with 2.8 million followers that provides guidance to new mothers—recently decided to remove all the pictures she had previously posted of her children.

The discourse surrounding "sharenthood," or the inclination of parents to broadcast their children's lives online, has been fervently ongoing for some time. The everyday choices made by parents have a significant, yet often undervalued, impact on the digital legacy of young individuals and their subsequent life trajectory.

Technological advancements have introduced fresh challenges for parents. The latest development in artificial intelligence is the emergence of image-generating tools. By inputting a series of descriptive terms into a text field, AI can generate a visual representation of the described subject. The datasets for these AI-driven generative systems are frequently sourced from the open internet.

While it is improbable that my daughter's Instagram photos would be processed through such an AI assembly line, resulting in her likeness appearing in someone's creative AI-generated artwork, once images are disseminated on the web, they can be exceedingly difficult to eradicate completely.

I do share photographs with friends and family via secure, private messaging applications. However, these closed networks are fundamentally distinct from public postings on the open internet.
