I had an experience some years ago, which taught me something about the ways in which people make a bad situation worse by blaming themselves. One January, I had to hold two funerals on successive (连续的）days for two elderly women in my community. Both had died “full of years”, as the Bible would say. Their homes happened to be near each other, so I paid condolence (吊唁）calls on the two families on the same afternoon.

    At the first home, the son of the deceased (已故的）woman said to me, “If only I had sent my mother to Florida and gotten her out of this cold and snow, she would be alive today. It's my fault that she died.” At the second home, the son of the other deceased woman said, “If only I hadn't insisted on my mother's going to Florida, she would be alive today. That long airplane ride, the sudden change of climate, was more than she could take. It's my fault that she's dead.”

    You see that any time there is a death, the survivors will feel guilty. Because the course of action they took turned out badly, they believe that the opposite course—keeping Mother at home, putting off the operation—would have turned out better. After all, how could it have turned out any worse?

    There seem to be two elements involved in our willingness to feel guilty. The first is our pressing need to believe that the world makes sense, that there is a cause for every effect and a reason for everything that happens. That leads us to find patterns and connections both where they really exist and where they exist only in our minds.

    The second element is the view that we are the cause of what happens, especially the bad things that happen. It seems to be a short step from believing that every event has a cause to believing that every disaster is our fault. The roots of this feeling may lie in our childhood.

    A baby comes to think that the world exists to meet his needs, and that he makes everything happen in it. He wakes up in the morning and summons the rest of the world to its tasks. He cries, and someone comes to attend to him. When he is hungry, people feed him, and when he is wet, people change him. Very often, we do not completely outgrow that childish view that our wishes cause things to happen.

    A survey has shown that what you do on a plane can be determined by which nationality is listed on your passport.

    According to the results of an international passenger survey, Australians are the biggest drinkers on board with 36 percent choosing to down the hatch, compared to 35 percent of Americans and 33 percent of Brits.

    The Airline Passenger Experience Association(APEX) spoke to around 1,500 people, aged 18 and older, who have travelled by plane at least once during the last three months and were living in the United States, United Kingdom, Germany, Japan, China, Singapore, Australia and Brazil.

The results found Chinese travelers are most likely to nod off once the seat-belt sign switches off. They are also the first to take out their credit card for some in-flight shopping and the biggest fans of gaming. Americans on the other hand like to use their time in the air more productively—- when not drinking—- choosing to work while flying at 35,000 feet.

Meanwhile, Brits and Germans are the best at making chat with random strangers—-spending 50 percent more time than any other nationality. Comparatively, Brazilians conduct their conversations online via email, messaging apps or social media.

    Despite plane food having a bad reputation, seven out of ten interviewees said they were happy to eat up on the selection of in-flight snacks and meals. In-flight magazines were also popular with four out of five passengers.

    The international flyers did however express their desire for better in-flight entertainment. “The industry has greatly improved the comfort, entertainment and onboard service, and passengers are accepting those improvements” said Russell Lemieux, APEX executive director. “At the same time, passengers are demanding more from their air travel experiences which will drive more improvements touching all aspects of the journey. ” he added.

In many ways, Providence Mount St. Vincent in Seattle is a typical senior living community. It is home to about 400 elderly people and provides them with different types of assistance. However, it is also the Inter-generational Learning Center—a preschool where children and seniors have the chance to bond（结成友好的关系）.

    Established in 1991, the ILC's purpose is to allow kids to learn about acceptance while also being nurtured. It also aims to help seniors develop a greater sense of self-worth and strengthen social interactions. Babies to prekindergarten-aged children are placed into six different classes at the ILC. The kids attend art and music classes, as well as story time and exercise time with the seniors. Marie Hoover, ILC director, said that interacting with the seniors has proven beneficial for the young ones, making them more open-minded.

    “For the ILC children, interacting with the residents is simply part of their day-to-day life here and the way aging is 'normalized', which may be the most important benefit they receive,” Hoover said.“ I've had parents call me years after their children have graduated from our program to let me know about some incidents when their child was the first to warmly greet someone who happened to be in a wheelchair.”

    As for the seniors, they're delighted by the companionship the children provide. The children bring so much energy and joy to our residents. Many of residents are widows or widowers and can become lonely. Their adult children may still be working, so they may not get to see them as often as they would like. Having the children stay with the old makes our residents feel they are still part of a community. The young and the old connect and learn from one another at this unique facility.

    Wolves travel shorter distances and move slower during snowfall events, according to new research by University of Alberta biologists. The effects were most pronounced at night, when wolves hunt, and behaviour returned to normal within a day. Wolf tracks across snow in northeastern Alberta.

    "Our findings suggest that there is something about actively falling snow that causes wolves to slow down," said Amanda Droghini, a former MSc student in the Department of Biological Science and lead author on the study. "We don't know the exact mechanism behind that. It's unlikely that they were staying still because they were feasting on a recent kill. Instead, active precipitation(降雪量)might affect wolves' hunting abilities. Like rain, snow clears the air column of scent molecules. So, maybe falling snow makes it harder for wolves to detect the smell of prey."

    Over the course of two winters, the researchers used remote cameras to disclose snowfall events and estimate snow depth. To study wolf movement, they collected telemetry(测距仪) data from 17 wolves to calculate travel speed and duration, as well as resting periods. It is the first study to examine how large flesh-eating animals respond to snowfall events.

    With the effects of climate change on precipitation in the north forest region uncertain, it is difficult to predict the implications for wolf populations. Studies such as these increase our understanding of how large mammals react to normal snowfall events, but the type and amount of winter precipitation will likely have an impact on animal behavior and the energetic cost of movement.

    "Winter is already challenging for many wildlife species because moving through snow requires more energy. Snow can also make it harder for animals to access food resources," said Droghini, who conducted the research under the supervision of Professor Stan Boutin, Alberta Biodiversity Conservation Chair.

    "Anything that increases those costs, such as increased rain-on-snow events, could lead to lacking in nutrition, poor body condition, and even starvation as animals are unable to make up for those additional costs. That is one of the worst-case scenarios(设想)but, in truth, we know very little about potential changes to precipitation patterns and how wildlife will respond to those changes."

    In the near future, IoT (Internet of Things) will drive huge innovation (革新) in the way our food is grown. Plants will have a "voice", not a human voice, but a voice based on data that can tell people, computers, and machines when, for example, they are thirsty, or need more sun, medicine, etc.

    Take vertical (垂直的) farms, for example. Farming is moving indoors where the growth of plants can be monitored and controlled. The facilities are built vertically, so growing areas can be put in piles. This greatly reduces the amount of land needed for farming.

    From an IoT point of view, vertical farms are connected in two ways. First, small sensors (传感器) in the soil or connected to plants tell a control system exactly how much light, water, and nutrients are needed to grow the healthiest crops. Sensors will also tell vertical farmers when crops are nearing their peak for harvesting at just the right time to make sure it's still fresh when it reaches its final destination.

    Second, vertical farms will be connected to other networks and information systems, including databases that track local demand. For example, local restaurants may input when they need fresh food supplies. And vertical farmers could get that information so they know which crops to grow in what quantities. This type of IoT system would have been unimaginable a generation ago.

    Today, vertical farms are being experimented. Yet, the numbers point to a bright future for the industry, especially as the world's population continues to grow. For example, Green Sense Farms in Chicago is able to harvest crops 26 times a year using 85 percent less energy, one-tenth the water, and no pesticides. A side benefit of lower energy use is lower CO₂ output of two tons per month, with the added benefit of creating 46 pounds of oxygen every day.
