【推荐1】Scientists are taking the study of archaeology (考古学) to a whole other dimension: space. For the first time, researchers are examining the ways humans live on the International Space Station (ISS), more specifically how they live culturally and materially, since it began orbital operations in 2000.

The project, involving daily photography of various ISS areas, was developed in 2015 by professors Justin Walsh of Chapman University in California, and Alice Gorman of Flinders University. The Earth-based scientists are working with astronauts to monitor changes in one-meter-square areas at the space station.

According to Chris Young of Interesting Engineering, for their first experiment, the astronauts are creating the equivalent of an earthen test pit (探坑) by marking out five areas within the space station. This test will focus on the kitchen table, workstation, payload rack (载荷机架) and a wall near the washroom and a section of the laboratory module, Destiny. Astronauts will then take daily photographs over a period of 60 days to know how the different spaces are used by the crew. For the first 30 days, images will be taken at about the same time each day and then at random times for the remainder of the experiment.

The archaeologists plan to study the images to better understand how the astronauts have interacted and adapted in the space in the 20 years when the ISS has orbited Earth, and how it has affected the crew’s ability to solve technical, engineering and medical issues, reports Leonard David of Space.com.

Original plans called for the ISS crew to swab (用拭子擦拭) surfaces for biological data and make sound and video recordings, but these ideas were given up so the project could begin sooner. Walsh tells Space.com he hopes the project will help find ways for future habitat designers to do their work better.

“The advantage of archaeology is that it shows us what people actually do, rather than what they think, or say, they do,” Gorman says.

【推荐3】Leonardo DiCaprio cares about climate change and has made environmental protection his life’s work. Besides leading his own environmental organization, the film star sits on the board of several other organizations, and his efforts have been celebrated by the United Nations.

But while many Hollywood stars are environmentally aware(意识到的)off screen, a new study shows the movie industry isn’t doing nearly enough on screen to keep climate change in everyday conversation. Researchers studied 37,453 scripts (剧本), looking for 36 climate keywords like “climate change”. They found only about 2.8% had any mention of the keywords. However, the word “dog” was mentioned 13 times more than all 36 climate words.

The study was published with a guidebook, Good Energy, to help screenwriters to focus more on climate change in movies and TV shows. The book was written after discussion with over 100 screenwriters and producers, as well as climate experts. Information about climate has an important part in the book, along with suggestions on how to shape characters and offer climate solutions on screen, Katherine Oliver, who helped with the print of the book, said, “Our goal should be to bridge the gap between the world we live in and the modern world we see on TV.”

Salire(讽刺)is used in Don’t Look Up , which stars Leonardo DiCaprio and Jennifer Lawrence in a story satirizing the worlds cold reaction to climate change. Writer-director Adam McKay was among those who joined the discussion about the book. “We’ve seen how the film has created more conversation to call on people to look up,” McKay said.

Supporters of the book call this just the start and say it’s up to Hollywood to tailor scripts so that they can mirror the terrible situation the world is facing in real life. If we’re doing a scene(场景)in a supermarket, let there be people refusing to use plastic bags. Or if we’re doing scenes where we can be modeling healthy eating, then let’s have a system that can offer clean water.

【推荐1】How can a large city find water for 10 million people if it is in the desert? Fog-catching nets on hills around the city of Lima, the capital of Peru, could solve the city’s water shortages for good. A twenty-meter high net tower will soon be displayed in the city as a solution to the problem.

Peru’s capital city has just one inch of rain a year. The city sees high annual temperatures and water consumption rates. Located in a desert, the city’s temperatures are higher than world averages. However, a unique feature of Lima’s weather offers a way of meeting some of this demand. Located on the coast, Lima’s surrounding hills are constantly bathed in waves of fog coming off the Pacific Ocean, and the moisture (湿气) taken in by plants ensures they stay green year-round.

Inspired by fog nets placed by rural communities across the continent, Alberto Fernandez, a Chilean architect currently studying for a Ph.D. from University College London, has designed a series of towers and fog-catching nets. They can collect as much as 1,000 liters of water per day, amounting to 3.6 million liters per year, if enough are put into use. Their towering structure allows them to get into the clouds, collecting more vital water vapor (蒸气), and their unique shape means that no matter the direction of the wind, the moisture-rich fog will strike some part of the structure directly.

The water will largely be used for agriculture — as the water would require filtering (过滤) before consumption — helping free up resources for city residents. Cheaper than filtering water from the Rimac River, these towers and nets, which Fernandez says could be built up to 200 meters high, are part of a series of designs for the Lima 2035 project. It aims to change current desertification and create a new place for sustainable and human-centered food systems that promote healthy diets and improve incomes in the driest city on Earth.

Sometimes people call ours a “throwaway society”. That means we are always throwing away old things and buying new ones.     2     For example, if your brother is old enough not to play with his plastic bike, why not give it to another family who has a little kid so that they don't need to buy one? And one less large plastic toy doesn't need to be produced.

    3     Many organizations will pick it up right in front of your house and some towns even require(要求) it. Make sure you encourage everyone in your house to think whether things can be reused or recycled before they're thrown away.

Almost everyone likes traveling. But next time before you travel around the world, take a look at your own backyard. Is there a place where you could plant a tree or put in a little fruit or vegetable garden? If so, get there and get your hands dirty. Then you can watch with pride as your tree takes root, and your garden plants grow into big plants full of ripe, red tomatoes or tiny-juicy blueberries.     4    .

【推荐3】I’ve just asked Julie Gray, a biologist at the University of Sheffield, which species she thinks would be the last ones standing if we don’t take transformative action on climate change. “I don’t think it will be humans. I think we’ll go quite early on,” says Gray. Humans probably won’t be among the survivors, partly because humans produce young extremely slowly and generally just one or two at a time.

It may seem like just a thought experiment. But discussing which species are able to survive climate change is disturbingly concrete. As a report stated recently, one in four species currently faces extinction, which is closely linked to climate change. While the seriousness of climate change is undeniable, we can make some educated guesses about which species will have a better shot at going far.

According to Jen Lau, a biologist at University Bloomington, heat tolerant and drought resistant plants, like those found in deserts, are more likely to survive. So are plants whose seeds can be spread over long distances, for example by wind or ocean currents. Plants that can adjust their flowering times may also be better able to deal with higher temperatures.

We can also look to history as a guide. Cockroaches adapted to an increasingly dry Australia tens of millions of years ago, by starting to dig holes in soil to hide. Cockroaches also tend to not be picky eaters. Having broad diets means that climate change will be less of a threat to them.

Furthermore, species called “mobile generalists” by experts can move and adapt to different environments and are more likely to last long in face of climate change. For example, deer in the US are common in suburban areas and manage to live where forests have been removed or are regularly disturbed.

Certainly, some animals would also survive if they could find a buffer: an area that is relatively protected from climate change’s consequences, such as deep sea canyons, underground caves.
