    What's more exciting than having a fresh hot pizza delivered to your door? How about having it brought to you by a robot? Thanks to Domino's Robotic Unit or DRU, that just became a reality! On March 8, the three-foot tall robot delivered its first pizza to some lucky residents in Brisbane, Australia.

    The fully autonomous DRU is the result of a cooperation between Domino's Pizza Australia and Marathon Robotics.The 450-pound machine that travels at a maximum speed of 12.4 miles an hour can traverse a distance of up to 12 miles and back, before requiring a battery recharge. LIDAR, a laser-based sensor technology similar to the one used in self-driving cars, enables DRU to detect and avoid obstacles, while traditional sensors, much like those used in vacuum robots ensure its path is safe as it heads to its destination.   

    The robot can fit up to ten pizzas and even has a separate cold area to accommodate drink orders.To access their fond, customers have to enter the unique code provided by the company.This is not only ensures that they pick up the right pizza, but also prevents the pies from getting stolen.

    Scientists expert additional DRU's to be ready for service in their various Queensland locations within the next six months. But don't expect these super cute robots to replace humans anytime soon. According to Domino's the DRU still needs extensive testing, which the company believes could take up to two years.

    And then there is also the issue of regulations.The public use of autonomous vehicles is still banned in most countries.But Don Meij, the CEO and Managing Director of Domino's Pizza Australia New Zealand Ltd, is not worried.He is “confident that one day DRU will become an   integral part of the Domino's family.”

    Have you ever considered all the English expressions that include words about clothes? Let's have a look.

    People wear pants to cover the lower part of their bodies. We sometimes say that people who are nervous have ants in their pants. Sometimes, people may get caught with their pants down. They are found doing something they should not be doing. And, in every family, one person takes control. Sometimes a wife tells her husband what to do. Then we say she wears the pants in the family.

    Pants usually have pockets to hold things. Money that is likely to be spent quickly can burn a hole in your pocket. Sometimes you need a belt to hold up your pants. If you have less money than usual, you may have to tighten your belt.

    I always praise people who can save their money and not spend too much. I really take my hat off to them. Yet, when it comes to my own money, I spend it at the drop of a hat, which means I instantly spend it.

    Boots are a heavy or strong kind of shoes. People who are too big for their boots think they are more important than they really are. I dislike such people.

    My father is an important person. He runs a big company. He wears a suit and tie, and a shirt with sleeves that cover his arms. Some people who do not know him well think he is too serious and never shows his feelings openly. But I know that my father wears his heart on his sleeve.

My wife and I were at a crowded grocery store not long ago. It was a weekday evening, cold and wet—and tense. People were carelessly blocking aisles, cutting one another off with their carts.

    Things got worse at the checkout line. The cashier scanned a man's discount card, but he misread the savings on her screen as an additional charge. He decided she was acting deliberately and began to argue.

    "She is being spiteful (恶意的)!" he yelled. "This is unbelievable."

    Other customers looked away as the cashier tried to reason with him. She called a manager, who accompanied him to customer service. Shaken, she moved to the next customer in line.

We've all witnessed uncomfortable scenes like this in public places. The grocery scene was another example of how our trust in others has eroded. But it was also a teachable moment on how we can rebuild our faith—starting with just one person.

    Back at the grocery store, my wife and I reached our uneasy cashier. I grabbed a bottle of water from a nearby cooler and handed it to her. "We felt bad about how that man treated you and wanted to buy this for you." I said. Her face lit up, and we talked as she scanned our items. She told us she had been working that evening through severe foot pain and would be having surgery later that week. We wished her well in her recovery, and she thanked us as we left.

    Those are the balancing acts, the moments of responding social and emotional pain with healing, which will add up to restore trust among people. You can start that pattern in someone else's life, even in a place as ordinary as the neighborhood grocery store.

    Tiny microbes(微生物)are at the heart of a new agricultural technique to manage harmful greenhouse gas. Scientists have discovered how microbes can be used to turn carbon dioxide into soil-enriching limestone(石灰石), with the help of a type of tree that grows in tropical areas, such as West Africa.

    Researchers have found that when the Iroko tree is grown in dry, acidic soil and treated with a combination of natural fungi(霉菌)and other bacteria, not only does the tree grow well, it also produces the mineral limestone in the soil around its root.

    The Iroko tree makes a mineral by combining Ca from the earth with CO2 from the atmosphere. The bacteria then create the conditions under which this mineral turns into limestone. The discovery offers a new way to lock carbon into the soil, keeping it out of the atmosphere. In addition to storing carbon in the trees, leaves and in the form of limestone, the mineral in the soil makes it more suitable for agriculture.

    The discovery could lead to reforestation(重新造林)projects in tropical countries, and help reduce carbon dioxide in the atmosphere in the developing world. It has already been used in West Africa and is being tested in Bolivia, Haiti and India.

    The findings were made in a three-year project involving researchers from the Universities of Edinburgh, Granada, Lausanne and Delft University of Technology. The project examined several microbiological methods of locking CO2 as limestone, and the Iroko-bacteria way showed best results. Work was funded by the European Commission under the Future Emerging Technologies (FET) scheme.

    Dr Bryne Ngwenya of the University of Edinburgh's School of GeoSciences, who led the research, said: "By taking advantage of this natural limestone-producing process, we have a low-tech, safe, readily employed and easily operating way to lock carbon out of the atmosphere, while improving farming conditions in tropical countries?
