1 . The parents’ interpersonal strength, such as kindness, love, and social intelligence, is one of the salient points in nurturing their children. As social psychologist John Bowlby puts it, “We do as we have been done by.”
Here is the example of my grandmother. When other children came over to play with my mother, my grandmother would fix them delicious butter sandwiches-the crusts (面包皮) delicately removed from the bread for “the guests” but unavoidably left on for her own children. This is how we ought to treat guests in our home-guests are worthy of kindness, but you are not. The kindness that my grandmother modeled and instructed her children to emulate (效仿) was not ultimately what they experienced - kindness was seen but not felt.
Generally, we often treat others the way we ourselves were treated. So much of what we learn as children and adults is experience-dependent. First-hand experience, especially when repeated over time, literally shapes the brain and nervous system, with downstream consequences for the way we engage with the world around us, deal with emotions, and behave socially.
We don’t learn to love by being instructed to love; we learn to love by experiencing love. We don’t learn kindness by being told to be kind; we learn kindness by experiencing kindness in our darkest moments. Recent research shows that children who received help while playing a game were more likely to share with another child, possibly motivated by feelings of gratitude to the person who helped them. They could learn that they don’t just repay the kindness but they need to pay it forward.
This transforms one of the key questions about raising kids: Perhaps we should ask not how to teach our children kindness, but how we want our children to experience kindness from us. If we want to create a kinder society, we might start with policies that ensure kinder treatment of kids. This means reimagining our education and foster care systems around compassion and support. Science tells us that experiences of kindness in childhood have long-term, biological, intergenerational effects on children’s development; our parenting and political systems should reflect the science.

3 . Hummingbirds occupy a unique place in nature: They fly like insects but have the bone and muscles of birds. According to Bo Cheng, a professor in Mechanical Engineering at Penn State, hummingbirds have incredible agility (敏捷) when flying through the air, which is why their flight behavior is often mimicked in the design of drones and other flying vehicles.
Using a new modeling method, Cheng and his team gained new insights into how hummingbirds produce wing movement, which could lead to design improvements in flying robots. “We essentially analyzed how the muscles and skeleton (骨骼) work in hummingbirds to flap the wings,” said Cheng. “The traditional methods have mostly focused on measuring the activity of a bird or insect during natural flight or in an artificial environment where flight-like conditions are reproduced. But most insects and, among birds specifically, hummingbirds are very small. The data that we can get from those measurements are limited.”
The researchers employed various methods to inform and adjust their model. With this model, they uncovered previously unknown methods of hummingbird wing movement. The discovery was that hummingbirds tighten their shoulder joints in both the up-and-down direction and the twisting direction using various smaller muscles.
“It’s like when we do fitness training and a trainer asks us to tighten our core to be more agile,” Cheng said. “We found that hummingbirds are using a similar kind of procedure.” They tighten their wings in the twisting and up-and-down directions but keep the wings loose along the back- and-forth direction. So their wings appear to be flapping back and forth only while their power muscles, or their flight engines, are actually pulling the wings in all three directions. In this way, the wings have very good agility in their motion.
While Cheng stressed that the results from the new model are predictions that will need confirmation, he said that it has suggestions for technological development of flying vehicles. “Even though the technology is not there yet to fully mimic hummingbird flight, our work provides essential methods for informed mimicry of hummingbirds hopefully for the next generation of agile flight systems.”

5 . In Belgium, a company called HydroVolta is improving ways to take salt water and turn it into fresh water under the Horizon-funded SonixED project.
The vast majority of the earth’s water is salt water. Only 3% is fresh water and less than one third of that is accessible, the rest being locked away in glaciers and groundwater. “We will need to treat salt water so people can drink it and industry can use it,” said George Brik, chief executive officer of Hydro Volta. “But with current technologies, desalination (脱盐) requires high operational costs. On top of that, existing technologies use high amounts of energy and chemicals.”
The basic technique now to turn salt water into fresh water is electrodialysis (电渗析), where a kind of membrane (隔膜) is used to separate salt from water. But the method has a weak point: the membrane gets dirty easily and requires chemicals and high pressure to clean. That in turn involves large amounts of energy. Under SonixED, HydroVolta has developed ultrasound technology that keeps the membrane clean in a much more efficient way.
Energy use in this field depends on pressure, which is measured in a metric unit known as bar. Existing technologies to desalinate seawater take around 50 to 80 bar, while the new desalination technology uses just one to three bar. What’s even better is that a greater amount of fresh water can now be generated. “Existing technologies waste around 60% to 65% of the seawater that’s taken in,” said Brik. “Our new technology improves the situation. If we take in 100 litres of seawater, we can produce 65 litres of drinkable water.”
HydroVolta thinks this technology will be beneficial to larger companies that generate drinkable water as well as to industrial businesses that need water to fuel their operations. Meanwhile, Brik says the new desalination technology may need a push from governments to encourage a bigger demand. “They can be the first customers,” he added.

6 . The power of human language comes not only from the precision of its signals and the complexity of its grammar but also from its links to cognition (认知). Babies as young as 3 months have begun to link language and core cognitive capacities.
Previous work in the lab had found that for babies aged 3 to 4 months, listening to both human vocalizations (发声) (their native language) and non-human primate vocalizations (calls of monkeys) boosted cognition. It remained unknown whether all human languages would have this advantageous effect.
In a new study, the researchers considered English-acquiring 3-to 4-month-old babies’ responses to two non-native languages (German or Cantonese) — in the context of the classic object categorization task. In this cognitive task, babies first viewed a series of “familiarization” images from one object category (e.g., dinosaurs). Then they viewed two new “test” images at the same time: a new example from the familiarized category (e.g., another dinosaur; “a familiar object”) and a new model from a novel category (e.g., a fish; “a novel object”). Babies’ ability to distinguish between the familiar and novel test images, measured by their looking times, indicates whether they have formed the object category.
Crucially, babies’ success in the task depends upon the sound information that accompanies the visual images presented during familiarization. “We found that German, which is phonologically (音系地) ‘near’ to English, facilitated object categorization. But Cantonese, which is phonologically ‘distant’, did not,” said Danielle Perszyk, lead author of the study.
“Babies’ responses to the two non-native languages tested, considered in combination with their responses to English and to the sounds of monkeys，are consistent with the possibility that babies’ earliest links to cognition originate from two distinct mechanisms. Only one of them is used specifically for human speech,” she added.
When babies are 3 to 4 months old, vocalizations of non-human primates may boost their cognition by engaging another system, one not specialized for speech. However, the cognitive advantage is short-lived: only lasts for 2 to 3months. The study also provides the first evidence that babies’ increasingly precise cognitive tuning to the sounds of their native language sets restrictions on the range of human languages they will link to cognition.

7 . Whales are known for their majestic (雄伟的) songs that travel through the ocean depths, but the reasons behind this behavior have long puzzled scientists. Recent research reveals this mystery, suggesting that whales possess a unique voice box that enables their powerful voice, a feature not found in other animals.
In a study published in the journal Nature, Coen Elemans and his team from the University of Southern Denmark examined the voice boxes. By conducting experiments, the researchers identified the tissues responsible for producing sound.
Whales, whose ancestors were land-dwellers around 50 million years ago, have developed their voice boxes over millions of years to adapt to underwater communication. Unlike humans and many other mammals (哺乳动物) , whales lack vocal cords and instead have a unique U-shaped tissue in their voice boxes. This specialized structure allows them to intake large volumes of air and generate sounds by pushing this tissue against a cushion of fat and muscle, a mechanism essential for their deep-sea sound.
The significance of this research is highlighted by Jeremy Goldbogen, an associate professor at Stanford University, who describes it as the most comprehensive study to date on how whales vocalize. He emphasizes the need for further exploration to these marine giants. For instance, humpback whales are known for their sound that can travel vast distances across oceans, serving as a form of communication within whales.
Joy Reidenberg, a whale expert, says, “More experiments are needed to confirm the study’s conclusions and understand how these creatures use their voice boxes to communicate in the ocean.”

8 . Early one morning, servers at an Egyptian restaurant began their usual preparations for the day. They laid out rows of desserts. But the offerings weren’t for customers. Instead, within an hour, staff from an organization called Tekeya had arrived to take away 135 portions of perfectly eatable dishes. The desserts — made a day earlier — weren’t considered fresh enough to eat.
Throughout Egypt, which boasts a rich culinary (烹饪的) history, such views aren’t uncommon. Now, though, with a global reflection on the food chain and its role in the climate crisis, attitudes in Egypt are slowly changing.
The restaurant is one of around a dozen across the Egyptian capital that Tekey’s staff visits each day in a quest to stop fit-for-consumption food from being dumped. Restaurants pay a small annual fee that allows them to alert Tekeya’s staff whenever they have unsold food. Personal users of Tekeya’s app can then buy that food at half price, or either the restaurants or the users can request Tekeya to deliver the food to a food bank or charity of their choosing. In total, up to 40 plates are saved from going to the trash each day.
“I’ve seen several platforms helping fight food waste across Europe. It’s uplifting to find one that does the same here in Egypt, ” says the manager, who has been using the app for three years.
In 2019, Menna Shahin had an idea particularly inspired by a festival, which brings about both celebration and waste. “I would put so much thought into how to deal with food responsibly without harming the environment, and how to minimize my excess (过度的) usage,” Ms. Shahin says. “I thought to myself, why not assist everyone to deal with their excess food wisely?”
Ms. Shahin ended up co-founding Tekeya along with her husband, Max Hartzen. By Tekeya’s second year, some 10, 000 discounted meals were ordered during one month, with users choosing to donate roughly a quarter of those to charities.

9 . You may have read that to stay fit and healthy, you need about 30 minutes of exercise each day, at least five days a week. New research suggests that the time we need to spend on daily workouts could be less than that.
Edvard Sagelv, a researcher at UiT The Arctic University of Norway, was part of a team that found being sedentary (久坐的) more than 12 hours a day was associated with a 38 percent higher death risk. This was only the case for individuals who managed less than 22 minutes of medium to high intensive physical activity a day, however, and it is relatively easy to achieve that minimum by taking a brisk (轻快的) walk.
“In research on physical activity, fast walking is estimated to be four kilometres an hour,” he said. Although it may not seem like a lot, it depends on a person’s fitness level. “It is interesting that 4 km/h — a pace achievable for the vast majority of the population — is what it takes to really invest in your physical health,” he added.
For a walk to positively affect your heart, which will then impact your brain and your circulation, you need to “feel it”. To feel the work your body is doing, you need to walk at 4 to 6 kilometres an hour. If you wear a fitness tracker, aim for more than 100 steps a minute.
A recent study published by researchers at the Cambridge University found that just 11 minutes a day of moderate-intensity physical activities — a brisk walk — was enough to lower the risk of diseases such as heart disease, stroke and a number of cancers.
Lead author Soren Brage was not surprised by the findings. “Doing some physical activities is better than doing none. This is also a good starting position — if you find that 75 minutes a week is manageable, then you could try stepping it up gradually to the full recommended amount,” he said. The point is that a relatively short period of high-intensity exercise isn’t just better than nothing; it has a measurable and positive impact on health.
