I received a call today asking if I would be willing to bring food to a family in need. The mother was having a major operation and would be lying down for several weeks. Of course, I responded with an immediate “Yes!”. As I planned the meal in my head, I reflected on how many times over the years I had been asked to prepare food. I have done so countless times with a very open heart.

    But the truly amazing thing is that I have received double over the course of my life. When my mother passed away, our house was filled with fresh dinners for weeks. A woman from the church of our community stopped by each evening with some food. The gift of food was her small way of trying to ease our pain.

    Later in my life, when I was on bed rest during my pregnancy with twins, women of the church again stepped in to help. They arranged babysitting for my two-year-old daughter, and brought lovely dinners to our house. Even when I was put in the hospital, my husband would bring cooked meals to my hospital room. How we relied on these dinners to feed my tired husband and young daughter.

    Food is all about comfort. It feeds our bodies, but it can also feed our souls. When you hear people talking about their favorite holidays, it usually includes their feelings connected with sharing food. I know that I will have many more opportunities in my lifetime to prepare food for others. It is truly a gift I want to prepare and deliver to someone in need.

    Off the coast of Hong Kong, there are numerous beautiful places that have long stay hidden, just waiting to be discovered by travelers. We've done the hunting for you.

Tap Mun

    Located north of the Sai Kung island, Tap Mun is home to a remote fishing, community with a population of less than a hundred. Tap Mun is also widely known as Grass Island, and it's easy to see why — this 1.7sq km island is an expense of grassy hill populated by wandering cows, a perfect scene to set a milk advertisement.

    Tap Mun is highly sought after as a spot for both camping and kite-flying, while also boasting several rocky beaches. For a relaxing afternoon, take a walk along the 2km footpath and slowly take in the panoramic(全景的) 360-degree view while enjoying the cool breeze.

Tung Ping Chau

    For a rugged(崎岖的) island getaway, set off for a trip to Tung Ping Chau — an offshore island sitting in splendid isolation in Mirs Bay on the northeastern side of Hong Kong. As a part of the Hong Kong Geopark, Tung Ping Chau is among the eight sites specially chosen for conservation in light of its special geological significance. Its rich marine life also led to its designation(指定) as one of Hong Kong's four marine parks.

Po Toi

    Located just three kilometers away from Hong Kong Island's southeastern tip, Po Toi is a quiet place that will make you feel completely isolated from modern life. While just a stone's throw away from the busy life of Hong Kong, Po Toi seems to be miles away from the busy city life.

    Take a leisurely stroll (闲逛) along the main path on the island, as you approach a lighthouse located on the sides of the cliff. Along the way, do not miss the dramatic and unusual rock formations as you are amazed by the glory of the famous Turtle Climbing up the Mountain, Monk Rock, and Palm Cliff.

    Childhood is a happy time, right? Not necessarily. Consider these facts.

Depression(抑郁症) may occur in as many as 1 in 33 children.

    Once a child has an episode of depression, he or she has a 50 percent chance of experiencing another episode in the next 5 years.

    Suicide(自杀) is the 6th leading cause of death for 5-to-15-year-olds.

    If your child experiences 5 or more of these signs or symptoms for at least 2 weeks, he or she may be experiencing depression or mental illness.

    Sometimes, a child who causes problems at school or at home may actually be depressed, according to the American Academy of Child and Adolescent Psychiatry.

    If you think your child may be depressed, it's important to have your child treated. Discuss your child's problems with his or her doctor. The doctor may suggest a referral to a children's psychologist or psychiatrist.

    One morning, a blind boy sat on the steps of a building with a hat by his feet. He held a sign which said, "I am blind, Please help me."

    There were only a few coins in the hat. A man was walking by. He took out a few coins from his pocket and dropped them into the hat. He then took the sign, turned it around, and wrote some words on it. He put the sign back so that everyone who walked by could see the news words.

    Soon the hat began to fill up. A lot more people were giving the money to the blind boy. That afternoon the man who had changed the sign came to see how things were. The boy recognized his footsteps and asked." Are you the one who changed my sign in the morning? What did you write?

    The man said, "I only wrote the truth. I said what you said, but in a different way." What he had written was, "Today is a beautiful day, but I can not see it."

    Do you think the first sign and the second sign were saying the same thing?

    Of course both signs told people the boy was blind. But the first sign simply told people to help by putting some money in the hat. The second sign told people that they were able to enjoy the beauty of the day, but the boy could not enjoy it because he was blind.

    The first sign simply said the boy was blind, while the second sign told people they were so lucky that they were not blind. There are at least two lessons we can learn from this simple story.

    The first is: Treasure what you have. Someone else has less. Try your best to help those who need your help.

    The second is: Be creative. Think differently. There is always a better way.

    A robot created by Washington State University (WSU) scientists could help elderly people with dementia (痴呆) and other limitations live independently in their own homes.

    The Robot Activity Support System or RAS, uses sensors installed in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities. It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owner to objects like their medication or a snack in the kitchen.

"RAS combines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected," said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.

    Currently, an estimated 50 percent of adults over the age of 85 need assistance with every day activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial strain on the healthcare system by making it easier for older adults to live alone.

    RAS is the first robot researchers have tried to incorporate into their smart home environment. They recently published a study in the journal Cognitive Systems Research that demonstrates how RAS could make life easier for older adults struggling to live independently.

    "While we are still in an early stage of development, our initial results with RAS have been promising," Minor said. "The next step in the research will be to test RAS' performance with a group of older adults to get a better idea of what prompts, video reminders and other preferences they have regarding the robot."

Tropical cyclones (热带气旋), including hurricanes and typhoons, are now moving at a slower speed than they did decades ago, new research shows.

While having a cyclone travel with less speed may seem like a good thing, it's actually just the opposite. Wind speeds within the storm remain high, but the whole system itself moves slower, allowing punishing rains to stay longer over communities. "Nothing, good comes out of a slowing storm," says James Kossin, author of the paper. "It can increase the amount of time that buildings suffered from strong wind. And it increases rainfall."

In his paper, Kossin showed that from 1949 to 2016, tropical cyclones across the globe slowed their movement by 10 percent on average. In some regions (地区), the speed of those storms slowed even more as they hit land. In the western North Pacific, the decrease was much more manifest ― almost a third. That means a storm that may already hold more moisture (水分) will have time to drop more of it in each spot.

Kossin's work was based on details of almost 70 years' worth of storms, but he didn't try to determine what was causing the slowdown. Still, the change is exactly what he and other cyclone experts said, which would be expected from climate change. With the polar regions warming fester than other parts of the globe, that is changing the pressure and reducing the winds that push these storms.

Christina Patricola, a scientist, called Kossin9s work important and new and said she found it reliable. "I was not surprised by his findings," she says. "But I was surprised by the speed of the slowdown."

Kossin hopes that scientists will begin building models that show which places are likely to face the most risk. Given that storms in some regions are moving towards polar regions and already increasing in intensity (强度), cyclones causing unusually powerful rain may threaten places not normally in their paths. Scientists must take action to make those places suffer less from the disasters.
