4 . One billion people in the world are short of water. How can this problem be solved. Some suggestions have been to desalinate ocean water or to build enormous water pipelines from areas where water is abundant. (Suggestions such as these prove extremely expensive when they are actually used.) One possibility that scientists are considering is pulling icebergs from either the North Pole or the South Pole to parts of the world with a water shortage. Although many questions must be answered before such a project could be tried, moving icebergs seems a reasonable possibility in the future.
Engineers, mathematicians, and glaciologists from a dozen countries have been considering the iceberg as a future source of water. Saudi Arabia is particularly interested in this project because it has a great water shortage. Scientists estimate that it would take 128 days to transport a large iceberg (about 1/2 square mile) to Saudi Arabia. Yet the iceberg would be completely melted by the 104th day. Therefore, insulation would be essential, but how to insulate the iceberg remains an unsolved problem.
The problems in transporting an iceberg are numerous. The first problem is choosing the iceberg to pull. The icebergs that form in the North Pole are quite difficult to handle because of their shape. Only a small portion extends above the water — most of the iceberg is below the surface, which would make it difficult to pull. South Pole icebergs, on the other hand, are flat and float like table tops. Thus they would be much easier to move.
How can a 200-million-ton iceberg be moved. No ship is strong enough to pull such enormous weight through the water. Perhaps several ships could be used. Attaching ropes to an iceberg this size is also an enormous problem. Engineers think that large nails or long metal rods could be driven into the ice. What would happen if the iceberg splits into several pieces during the pulling. Even if an iceberg with very few cracks were chosen, how could it be pulled through stormy waters. Furthermore, once the iceberg reached its destination, very few ports would be deep enough to store it.
All of these problems must be solved before icebergs can become a reasonable source of water. Yet scientists estimate that it will be possible to transport them in the near future. Each year, enough icebergs form to supply the whole world with fresh water for a full year. In addition, icebergs are free and nonpolluting. As a solution to the world’s water problems, icebergs may be a workable possibility.

5 . Most animals living in crowded conditions have particularly strong immune systems, so it long puzzled researchers that honeybees do not.
Part of the answer, discovered in 2015, is that queen bees vaccinate their eggs by moving parts of proteins from disease-causing pathogens to them before they are laid. These act as antigens to trigger the development of a protective immune response in the developing young. But that observation raises the question of how the queen receives her antigen supply in the first place? Dr. Harwood wondered if the nurse bees were taking in parts of pathogens and passing them to royal jelly they were producing while eating the food brought to the hive.
To test this idea, he teamed up with a group at the University of Helsinki, in Finland, led by Dr Heli Salmela. Together, they collected about 150 nurse bees and divided them among six queenless mini hives equipped with baby bees to look after. Instead of honey, they fed the nurses on sugar water, and for three of the hives they added P. larvae, a bacterium causing a hive-killing disease, to the sugar water.
In this case, to stop such an infection happening, Dr Harwood and Dr Salmela heat-treated the pathogens and so killed them in advance. They also labelled the dead bacteria with a fluorescent dye, to track them easily. And, sure enough, it was confirmed that parts of P. larvae were getting into royal jelly released by those bees which had been fed with the sugar water containing that.
All told, these findings suggest that nurse bees are indeed, through their royal jelly, passing antigens onto the queen for vaccinating her eggs. They also mean the nurses are vaccinating baby bees as well, because baby bees, too, receive royal jelly for the first few days after they come out.

6 . On July 31, 1697, a French lawyer named Jacques Sennacques wrote a message to remind a cousin in the Netherlands to send him a relative’s death certificate. To prevent others from reading the message, the note was carefully folded, or “letter locked.” The technique was used before the invention of envelopes. However, for reasons unknown, the note never reached the recipient and was instead stored in a postmaster’s trunk, where it remained undetected for centuries. Now, a team of international researchers has deciphered (破译) the contents of the over 300-year-old sealed letter — without opening it!
The chain of events leading to this technology began in 2015 when MIT expert Jana Dambrogio got a call from Daniel Starza Smith, a researcher at King’s College London. “He asked me, ‘What would you do if I told you there was a trunk with 600 unopened letters?’”
The trunk had once belonged to 17th-century postmaster Simon de Brienne. Historians believe the post office stored the undelivered letters. That’s because, in the 17th century, it was the recipient, not the sender, who bore the postage cost. When Brienne died in 1707, he donated the trunk of letters to an orphanage. Somehow, the trunk eventually made its way to the postal museum, where it lay until recently.
Since opening the letters would destroy them, Dambrogio and her team decided to develop technology to unseal them virtually. They began by using a high-resolution X-ray scanner to create a detailed three-dimensional image of a sealed letter. While the writing inside showed up very clearly, the numerous layers of folded paper pressed close together caused the words to overlap (重叠).
To solve the issue, the researchers created sophisticated algorithm (算法) capable of deciphering the writing in the cleverly folded letter, crease by crease. The virtual opening allowed the team to read the contents “while preserving letter locking evidence.” The algorithm took almost five years to perfect. Once perfected, they used it to open four locked letters and fully decode(解码) the one from Sennacques.

7 . When the COVID-19 hit and supermarket shelves were empty, Chris Hall and Stefanny Lowey decided they no longer wanted to rely on others for food. The couple, who live on Pender Island in British Columbia, Canada, decided to start a year-long challenge where they wouldn't buy a single thing to eat. Instead they would grow, raise or catch everything—right down to sugar, salt and flour. Now, five months in, they say the challenge has changed their lives.
Chris, 38, said, “It has always been something that we have wanted to do. We have had a garden and grown vegetables for a long time already. When the COVID-19 hit, it gave us that extra push that we needed to do it. We were both out of work when we started, and with the reality check of grocery stores running out of items, it gave us even more motivation to see if we could look after ourselves.”
The pair spent the months before building a house for chickens, ducks and turkey as well as studying as much as possible to figure out where they would get all the things they needed. Chris adds, “We had to learn so many new things like how to grow mushrooms, process our Stevia plants, and harvest salt from the ocean. We spent a lot of time reading and studying online to figure out all the things we were going to need to do.”
Now after five months, they both feel its been going well but Chris admits the first few weeks were difficult. “The first three weeks were very challenging as our bodies adjusted to cutting out coffee, wine and sugar all on the same day,” he says. “After three weeks our energy levels balanced out and our wishes reduced and now we feel great.” Now February has ended. As they come through winter, they feel positive about continuing with this way of living, with their challenge officially ending in August.
