1 . About 12% of the total global energy demand comes from heating and cooling homes and businesses. A new study suggests that using underground water to maintain comfortable temperatures could reduce consumption of natural gas and electricity in this section by 40% in the US. The approach is called ATES, short for aquifer thermal energy storage(含水层热能储存).
“We need storage to absorb energy from the sun and wind. It’s crucial to creating affordable, reliable, and deeply environmental-friendly electricity systems. Most people are interested in batteries and other kinds of electrical storage. But we were wondering whether there was any opportunity to use geothermal (地热的) energy storage,” said first author A. T. D Perera. “With ATES, energy can be stored for a long period of time, without adding an additional burden to the grid (输电网).”
ATES is a pleasantly simple concept that takes advantage of the heat-absorbing property of water and the natural geological features of the planet. You simply pull existing underground water up and heat it at the surface in the summer with environmental heat or energy. Then you send it back down. It stays fairly hot because the Earth is a good insulator (绝热体).
“Unlike above-ground tank-based water or ice storage systems, ATES will not need space. It’s also more efficient and can support larger communities in cooling or heating than traditional geothermal heat pump systems that rely on heat moving with the underground soil,” added coauthor Hong Tianzhen.
A major benefit of ATES is that it will become more efficient as weather becomes more extreme in the coming years due to climate change. The hotter summers and severer winters could increase the amount of free thermal energy that can be stored with ATES. “It’s very much a realistic thing to do and this work is really about showing its value,” said Perera. “This technology is ready to go, so to speak. We just need to do it.”

5 . Animal populations across the world have been reduced by 69% in less than 50 years, according to a new scientific report. The report’s authors are calling for urgent action to restore the natural world.
The Living Planet Report (LPR) is produced every two years by the World Wide Fund for Nature (WWF) and the Zoological Society of London. The most recent report, released on October 13, 2022, shows that almost 70% of the world’s monitored wildlife was lost between 1970 and 2018. The report is based on research from 195 countries around the world. Data was collected from almost 32,000 populations of 5,230 species.
Although the average global loss of wildlife is 69%, the rate is greater in the global south. Latin America and the Caribbean in particular have seen the sharpest fall, having lost 94% of their wildlife since 1970. Across the world, the biggest drop was in freshwater populations of wildlife — including almost 1,400 species of mammals, birds, fish, amphibians and reptiles — which have decreased by 83%.
The report identifies several causes for wildlife loss, including hunting, farming, the loss of forests, pollution and climate change. However, the report also promotes solutions, such as designing less destructive food production systems, urgently protecting the Amazon rainforest, limiting the use of fossil fuels, and creating new laws to protect our natural environment.
Commenting on the report, Marco Lambertini, director general of WWF International, called the figures “terrifying”, and said “we need to help nature recover and not simply halt its loss.” In December 2022, world leaders are meeting in Montreal for the 15th UN Biodiversity Conference, also known as COP 15. The authors of the LPR say that this is an opportunity for a global plan to deal with wildlife loss and restore nature. “Government leaders must step up at COP 15,” said Lambertini. “The world is watching.”

6 . To produce the classic clothing, blue jeans, producers rely on indigo dye (靛蓝染料), the only molecule known to provide jeans’ unique, beloved color. While indigo itself naturally comes from a plant, growing demand for blue jeans throughout the 20th century gave rise to synthetic (合成的) indigo, which is now more commonly used.
Indigo is the dye that makes jeans blue, but it doesn’t mix with water. To dye clothes, usually, chemicals are needed to make the color stick to the cloth. But in Denmark, scientists have created a new way to dye clothes using an enzyme (酶), which is a kind of protein that can cause chemical reactions, instead of harmful chemicals. This new method is better for the environment and doesn’t use poisonous stuff.
The chemical process for dyeing blue jeans has persisted for the last century. Workers are exposed to the poisonous chemicals, which also pollute the environment near factories. Waste water from those factories often ends up in waterways, damaging local ecosystems and even dyeing rivers blue.
Ditte Hededam Welner, the study’s lead researcher, says their new enzyme works really well and is strong enough for making lots of jeans without breaking down. This enzyme makes dyeing with indican, which is like indigo, much less harmful to the planet — about 92% better than the old way.
However, the new method doesn’t fix all the environmental problems of making jeans. Making a single pair of jeans uses a lot of water — enough to fill many bathtubs — from growing the cotton to putting the final touches on the jeans.
Even though the new dyeing process is better for the environment, it’s not always easy or cheap to change to it. Welner’s team isn’t sure if jeans companies will find it easy or affordable to switch to this method. It costs a little bit more — just seven cents extra per pair of jeans — to use the enzyme for dyeing. But Welner believes it’s worth it because it’s much better for the environment.

9 . You may have visited antique stores and found cutting-edge goods in second-hand furniture stores, but have you ever stooping? On the streets of big cities at night, some young people are “looking for something”. Obsessed with the spiritual core of the old thing recycling, they fell in love with it. But what exactly is stooping?
In fact, this English word originally meant “bending over”, and now refers to a way of life of picking up discarded items and renovating and recycling old things, which originally emerged in New York and other foreign big cities.
Since the beginning of last year, the trend of “stooping” has spread to many big cities in China and many young people look for second-hand items such as discarded furniture on the streets, take home and repurpose them with a new look. In order to make the flow of information better, some “stoopers” have also built communities where group members can share “treasures” on the street with each other.
Mikiko, 27, is reportedly one of the first people in China to get involved in practicing stooping. At first, she posted online things that people no longer use, want to throw away, or exchange at home, and slowly hundreds of messages flooded in and since then, stooping has become more and more popular among young people. Mikiko admitted that she was surprised that the concept has become a hit on social media, as older generations often stigmatize picking up things from the street or using second-hand goods. “People like my mom consider stooping as’rubbish-picking’, and people will be looked down upon by doing this.” She even created an app called “Grecycle” where people can give away or take unwanted items for free, hoping people may realize that stooping can also be about doing good and helping others.
This generation of young people has given “new life” to old things, practiced social responsibility in their own environmentally friendly ways in life, and also contributed to the circular economy and sustainable society.
