1 . The green, natural forest absorbs carbon dioxide from the air through photo- synthesis (光合作用). There is another way of dealing with the climate crisis. That is setting up fields of dark-colored solar panels (太阳能电池板), also known as “solar forests”, which replace power stations that use fossil fuels such as coal and gas to make electricity, thus mitigating harmful emissions (排放) of greenhouse gases.
But since they are both relatively dark, they absorb a lot of solar radiation. Some of the energy is used for photosynthesis in natural forests or to produce electricity in “solar forests”, but most returns to the atmosphere, heating it up. Then what would be the more effective land use option in terms of the climate crisis: planting a forest, or building solar panels? This issue has long been debated by decision-makers around the world. Now, we may have an answer, thanks to a new study.
First, the researchers compared the impact of a forest on the climate crisis in a dry area to that of a solar farm in a similar environment. The researchers found that the albedo effect (反射效应) of both of these “forests” was similar, but that the absorption or prevention of carbon emissions was very different. It turns out that it takes 2.5 years for the heat emitted by solar farms to be balanced by the carbon emissions that are avoided, thanks to the energy they produce. In the case of a natural forest of similar size, it would take more than 100 years of photosynthesis to balance its heating effect.
The researchers also studied how the heating-cooling relationship changed in other climates and found that in more humid environments, the heating effect of planting large numbers of trees is smaller. And the break-even point is reached within 15 to 18 years.
“In dry places, building solar forests seems far more effective in addressing the climate crisis. Meanwhile, forests absorb about a third of annual carbon emissions and play a vital role in the global rain cycle, in maintaining biodiversity and in many other environmental and social contexts. Preventing them from being cut down and planting more trees in humid areas are of great significance,” explains one of the researchers in the study.

2 . Chaudhary weaves (编织) together lengths of rope and grass collected from the nearby riverbank in her village, skillfully shaping the materials into a gift box while instructing a group of women to follow suit.
The ropes being used were once the lifeline for mountain climbers tackling Nepal’s mountains and were then cast away. Diverse measures to remove such discarded materials have rocketed since 2019, when the government launched Clean Mountain Campaign.Around 140,000 tons of waste were collected on Mt. Everest alone, which were handled accordingly, either securely buried or recycled.
Some waste is now finding fresh life, transformed by skilled hands like Chaudhary’s into items to sell, thanks to an initiative led by Acharya, an owner of a waste processing business and an advocate for sustainable waste management. She has been working with the cleaning campaign, aiming at mountains like Mt. Everest.
“Metal waste goes through the recycling process, but we weren’t capable of recycling these ropes and cooking gas cans,” Acharya says. It didn’t occur to her that the waste which couldn’t be recycled could be reused until she met Rai at an art exhibition and a solution emerged.
Rai, a businessman dealing in craftworks, helped connect Acharya with Chaudhary and her team of craftswomen in hopes of unlocking the economic value of the mountain waste. With flexible hours, the project gives the craftswomen an opportunity to earn money even as they maintain their household responsibilities.
“While this seems insignificant compared to waste in the mountains, it’s a start. We can’t supply sufficient raw material with waste sorting and cleaning processes taking plenty of time and money,” Acharya says, desperate to expand the program to involve more women and treat more waste. But progress has been slow. “We need investment to mechanize the cleaning and processing of waste in the initial phase to provide the crafting team with enough materials to meet their demand,” she adds.

3 . Increased involvement from grandparents can be crucial in a child’s development. From helping children navigate stressful situations to giving kids that little extra bit of love and care, grandparents play an important role in the well-being of a child. Now, there’s scientific data to back this up.
According to a study of over 1,500 children, conducted by Professor Ann Buchanan from the Department of Social Policy and Intervention at the University of Oxford in the United Kingdom, children who have tight-knit relationships with their grandparents tend to have fewer problems, both emotionally and when it comes to their behavior. Besides, children also have less difficulty when interacting and maintaining relationships with others.
Kimberly Agresta, the co-founder of Englewood’s Agresta Psychotherapy Group, has also noticed in a study the significant benefits of allowing grandparents to be more involved in children’s lives. “If parents regularly involve grandparents in their child’s life early on, a child can develop real emotional closeness to their grandparents and begin to see them as a source of strong social support,” she stated in an interview. “So a child will feel they have other adults, aside from their parents, who care about them in the same way, and this adds to their sense of stability and security.”
She continued, “Stressful situations are less impactful to such children because they have other people in their lives who they have these attachments to and support from.” This is because grandparents are generally not responsible for disciplining or raising the child, and they’re able to love the child a little more freely and unconditionally than a parent, Agresta explained.
“Grandparents are a wealth of knowledge and information, and not only can they pass on valuable skills from real-life experience, but they can also share the past with their grandchildren,” added Agresta. “They can serve as historians, sharing various traditions and stories about when their own children were growing up, which create s a sense of continuity for a child.” So it looks like it may be time to set up a play date for your kids with their grandparents!

4 . Ariel Procaccia has thought a lot about how to cut a cake over the last 15 years. As the father of three children, he knows how hard it is to divide a birthday cake to everyone’s satisfaction. But it’s also because Procaccia’s work focuses on exploring the mathematical rules for dividing stuff up fairly. One way to do that is to think abstractly about dessert.
For decades, researchers have been asking the seemingly simple question of how to cut a cake fairly. The answer reaches far beyond birthday parties. A mathematical problem at its heart, cake cutting connects strict reasoning to real-world issues of fairness, and so attracts not only mathematicians, but also social scientists, economists and more. “It’s a very elegant model in which you can distill what fairness really is, and reason about it,” Procaccia says.
The simplest approach is called the “divider-chooser” method, where one person cuts the cake into two equal pieces in his view, and the other person picks first. Each receives a piece that they feel is as valuable as the other’s. But when personal preferences are taken into account, even the easiest rule becomes complicated. Suppose Alice and Bob are to divide a cake, and Alice knows Bob prefers chocolate, she may knowingly divide the cake unequally so the smaller piece contains more chocolate. Then Bob will choose according to his preference, and Alice will get the larger piece. Both of them are satisfied with what they get, but the meaning of fairness changes in this situation.
The cake is a symbol for any divisible good. When cake-cutting principles are employed to settle disagreements, they are potentially helping the world find solutions. Procaccia has used fair division algorithms (算法) to model food distribution. Social scientist Haris Aziz is exploring situations ranging from how to divide up daily tasks to how to best schedule doctors’ shifts in hospitals.
Even after decades of investigation, cake cutting isn’t like a simple jigsaw puzzle (拼图) with a well-defined solution. Instead, over time, it has evolved into a kind of mathematical sandbox, a constructive playground that brings together abstract proofs and easy applications. The more researchers explore it, the more there is to explore.

5 . “The mountains are calling and I must go” — the famous quote is from John Muir(1838-1914), who is described as “the wilderness poet” and “the citizen of the universe.” He once jokingly referred to himself as a “poet-geologist-botanist and ornithologist (鸟类学家)-naturalist etc. etc.!” He is known as the Father of American National Parks.
Famed documentary filmmaker Ken Burns recently said, “As we got to know him… he was among the highest individuals in America; I’m talking about the level of Abraham Lincoln, Martin Luther King Jr., and Thomas Jefferson— people who have had a transformational effect on who we are.”
So where is the quote from? Well, John Muir was a productive writer. Whether he was writing poetry or simply letters to his family, John Muir was always putting pen to paper. The quote is from within one of his many letters written to his sister:
September 3rd, 1873 Yosemite Valley Dear sister Sarah,I have just returned from the longest and hardest trip I have ever made in the mountains, having been gone over five weeks. I am weary, but resting fast; sleepy, but sleeping deep and fast; hungry, but eating much. For two weeks I explored the glaciers of the summits east of here, sleeping among the snowy mountains without blankets and with little to eat on account of its being so inaccessible. After my icy experiences, it seems strange to be down here in so warm and flowery a climate. I will soon be off again, determined to use all the season in carrying through my work—will go next to Kings River a hundred miles south, then to Lake Tahoe and surrounding mountains, and in winter work in Oakland with my pen. Though slow, someday I will have the results of my mountain studies in a form in which you all will be able to read and judge them. The mountains are calling and I must go, and I will work on while I can, studying incessantly (永不停息地). I will write again when I return from Kings River Canyon. Farewell, with love everlasting. Yours, John |

7 . A new study shows that female academics are significantly underrepresented in winning academic prizes and having awards named after them. Analysis of nearly 9,000 awardees and 346 scientific prizes and medals published in Nature Human Behaviour has found that men win eight prizes for every one won by a woman if the award is named after a man. These awards represent almost two-thirds of all scientific prizes. Female academics are, however, more likely to win awards that have been named after other notable female scientists, with 47% of those awards going to women and 53% to men.
Dr Katja Gehmlich, Associate Professor in the Institute of Cardiovascular Science at the University of Birmingham and joint lead author of the study, said, “The gender gap between awardees in scientific prizes is sadly a product of a long, systematic issue of poor representation of women in sciences. Despite decades of efforts to rebalance this issue, our study shows that women are still poorly recognized for their scientific contributions, and men are far more likely to win prizes and awards, in particular, if those awards are named after other men.
“It seems particularly shocking to me that awards named after women still see more than half of prizes going to men. We further propose a list of actions to address and overcome these issues but are aware this will be a long process. The Nominate Her movement is one way that the scientific community can begin to address this,” said Dr Gehmlich.
Prof Stefan Krause from the School of Geography, Earth and Environmental Sciences at the University of Birmingham and joint lead author of the study said, “Our data is indicative of much wider issues of gender inequality within sciences. Our current publication is an initial attempt to understand the causes of such striking gender inequality and to promote discussion on the subject within our scientific communities.”
“Research culture has a lot to do to improve the gender prize gap, as well as efforts to address the inequality that sees almost two-thirds of prizes currently named after men. More pathways may also be needed, such as renaming or getting rid of gender names associated with some awards,” added Prof Krause.

8 . “You like pottery (陶艺) more than you like science,” a family member said. I knew the comment was made lightly, but I felt frustrated and disappointed. I had worked so hard to achieve a balance between my scientific and artistic pursuits. Why was my creative side still seen as a weakness and a disturbance, in opposition to my science?
As a little girl, I created art by breaking up eggshells, dying them, and gluing them to a cloth. I also conducted science experiments with my mom, a high school science teacher, on the back porch. In college, I loved my chemistry courses and research work, and I regarded cooking as my creative outlet, hosting weekly dinner parties for friends.
Yet I heard time and again that creative expression and science were not possible together. When my college roommate concluded with a personality test that I was the “creative” type, the rest of my friends said that couldn’t be right, because “I was a scientist and therefore was not creative.” As I was preparing for graduate school and studying for the chemistry GRE test, I realized I talked about science the same way I would paint a picture, explaining concepts in broad strokes (粗线条地) — in part because I struggled to remember technical scientific terminology. I worried my way of thinking wouldn’t fit in with “proper” scientists. In the end, though, my desire to pursue a scientific career won out. I figured I would continue to find a way to balance my research with my creative pursuits, regardless of what others thought.
When in graduate school I found pottery, which I could pursue on evenings and weekends. After my first class, I was attracted. It has inspired me to more intentionally mix my art with my science. I keep a notebook at my lab table filled with words of mug (马克杯) designs inspired by my experiments. Through the challenge of getting my paper into its core concepts in such a way that it could be displayed on a mug, I gained a better understanding of my project. Pottery has now turned into a way for me to train my brain to be creative and think outside the box.
