It was the 50th anniversary (周年) of the moon landing last year. Astronomy lovers are not the only ones who are excited about it; publishers(出版商) are also offering a number of books to mark the event.

This retelling of the space race begins with the Soviet Union’s Sputnik satellite in 1957 to the historic Apollo 11 program twelve years later. The book offers details about the characters of the spacemen, engineers and others who made the U. S. space program a success.

Getting to the moon required a million hours of work, this book says. Accordingly, the story centers on the engineers, project managers and others who worked long and hard to get the Apollo program off the ground.

Packed with hundreds of photos (some are published for the first time), this book reads like a photo book of the Apollo 11 program. The photos are moments from spaceman training, as well as the excitement of liftoff, the historic landing and the return home of the three men.

A space historian examines the Apollo program in different ways: as a political (政治的) machine in the Cold War and an important cultural moment. The book explores different views on the U. S. moonshot project from scientists, politicians, the media and the public during the space race and beyond.

Macinley Butson was just 16 years old when she first had the idea to try and protect women from more — than — necessary radiation during breast cancer treatments—and now, her invention could be a game-changer in the medical field.

Butson, whose father works in medical physics, has always been interested in science. But she only began researching the harmful side effects of radiation treatment after her father discussed his experience with ineffective cancer treatments in his work. Since Butson had also recently lost a relative to breast cancer, she felt inspired to conduct her own research on the subject. She tried to begin her medical research by consulting scientific journals, but she found their academic terms almost impossible to understand.

She then turned to the Internet to find videos that taught how to read scientific journals. As she went deeper in her research, she stumbled upon a key bit of information: copper （铜）has been shown to be effective at protecting skin from radiation. An idea hit this Australian teen as she was viewing a film on medieval wars in her 10th grade history class. When she saw the scaled （鳞片） patterns of the mail （盔甲）,she was inspired to create a wearable protective tool out of copper. She then headed back online and watched videos on how to put together tiny scales. She made her own flexible scale-mail which she now calls SMART: Scale Mail for Radiation Therapy.

When her invention was tested in a laboratory setting, it reduced surface exposure to unnecessary radiation by 75%. And now Butson is working on getting her SMART into clinical settings for use.

There is a famous story about how Walt Disney was inspired to build Disneyland. The story goes that during an afternoon visit to Griffith Park located near the Burbank Studios, Walt took a seat while his two young daughters rode the merry-go-round. Walt thought there should be a place where both children and their parents could enjoy spending some time together in an environment that would be both entertaining and pleasing to the eye, so with this thought came the idea for Disneyland.

Walt's original plan was to build an eight-acre park located near the Burbank Studios that would be a place for his employees and their families. Those plans were put on hold because of the start of World War II. By 1952, Walt had created a special department that was devoted to planning his dream.

Finally in 1953, the first steps in building the park happened when Walt employed the Stanford Research Institute to make a survey to determine the best possible location for the future park. Considering population growth and the future freeway construction(建设),they finally found a location in Anaheim and 160 acres of land were bought for the site of the new park.

The building of the park was very expensive and to collect money for the project, Walt developed the idea of the ''Walt Disney's Disneyland'' television show. It turned out to be a marvelous idea—not only gaining the money to build the park but also presenting the park to the American public.

Construction officially began on July 21,1954, and it was an ambitious(野心勃勃的)building schedule of less than one year to complete the new park for the projected opening day. Walt watched over the park's construction and progress continued with just a few minor hold-ups. Finally，the park was ready for the Opening Day on July17,1955.

Saltwater and dry desert climate may not seem good for growing healthy produce,but that is exactly what a group of scientists has managed to do.Researchers from the UK-based Seawater Greenhouse Company have discovered a good way to farm fruit and vegetables simply by using solar power and salt water for watering and cooling in dry areas.

The company has developed plantation(种植园)projects in dry areas such as Australia, Abu Dhabi, Somaliland, Oman, and Tenerife. Although these places are dry, the plantations are able to grow thousands of pounds of produce simply by making ''cooling houses'' out of thick walls of cardboard(硬纸板).While glass greenhouses are designed to keep gardens wet and warm, the cardboard walls use evaporative cooling(蒸发冷却)to keep the inside of the plantations wet and cool.

An exciting new study says that plants grow well down below solar panels(太阳能板)and they produce more energy. The design of the waving-cardboard panels helps to cool down the wind coming from the outside. At the same time, a small solar-powered machine offers sea water at the top of the panels so at it can drop down through the walls of the cardboard for evaporation. This evaporative cooling skill creates the perfect conditions for farming produce in the dry areas. Additionally, since the seawater is repeatedly collected, the salt can be left onto the outside of the walls. Not only does this help to make the cardboard strong, it can also be collected and sold for increasing income.

According to Seawater Greenhouse founder Charlie Paton，you would only need about 10 square miles of ''cooling houses'' to feed all of Somaliland, which is a country of about four million people. Upon completing the company's Somaliland project in November 2017, it now produces about 300 to 750 tons of tomatoes every year. Paton says that he is very excited for his company to start even more projects in dry areas around the world.
