1 . Biar Kon, a 17-year-old student, whose parents were working in neighboring Sudan, moved to Nairobi, the capital of Kenya, to attend school. Once he _______, he needed to get some documents from the Sudanese embassy(大使馆). But when he went to look for the embassy, he couldn’t find it. He asked a few people for _______, and no one knew where it was. Then an older woman tapped him on the back.

The woman told Kon that she had seen him asking questions of multiple people as they _______, and she wondered if he needed money for food, or a place to stay. Then Kon realized that the woman thought he was _______.

They cleared up the _______, and the woman was able to offer her help. The woman’s _______ left a deep impression on Kon. And it inspired him to _______ five years later, when he moved to Boston, Massachusetts. One day, outside a coffee shop, he _______ a man who was begging for change. Kon _______ that moment five years earlier, when the woman in Nairobi had ________ him for a homeless person. So he went up to the man to see what he could do. “He told me why he was on the street—because he made a（n） ________ mistake when he was in high school, and he couldn’t get a ________ now,” Kon recalled. Kon bought the man some breakfast, and gave him a little bit of money.

Today, it’s an encounter he ________. For him, it is a ________ that you never know what people are going through unless you talk to them ________ — the way the woman in Nairobi made an effort to talk to him.

2 . Researchers at the Indian Institute of Technology (IIT) Madras have been working on a fascinating new way to identify people: using the ways of their breath. This idea could change how we unlock our phones and access secure places.

The key to this technology lies in the way we breathe out. Every person has a unique way of breathing air, which creates specific turbulence (涡流) patterns. The IIT Madras team, led by Prof. Mahesh Panchagnula, has developed a method of catching these unique patterns and using them as a biometric (生物特征识别的) signature, similar to how fingerprints are used today.

They conducted tests with breath samples from 94 people and found that their system could correctly confirm the person’s identity with an impressive accuracy of 97%. However, when it came to identifying someone without knowing who they were beforehand, the accuracy was around 50%. This means the technology is great at confirming if someone is who they claim to be, but it still needs improvement in recognizing people without any prior information. What makes this research exciting is its potential beyond just unlocking phones. It could play a significant role in personalized medicine. Since the way we breathe can give insights into our health, this technology could help doctors tailor treatments to individual patients more effectively.

In a similar study at Kyushu University in Japan, researchers developed an artificial system that identifies people based on how their breath smells. This system showed a high accuracy rate of 97.8% in identifying individuals. However, this method currently requires people to fast (禁食) for six hours before testing, indicating that it still needs to be improved to be more practical for everyday use.

These advancements in using human breath for identification are not just about adding another cool feature to our smartphones. They represent a significant step forward in biometric technology, which could have far-reaching implications in security, medicine, and personal technology. This research at IIT Madras and Kyushu University is pioneering a new way of using the unique patterns of our breath for identification purposes, potentially revolutionizing (变革) how we interact with technology and receive medical care.

3 . “A moth (飞蛾) to a flame” is often used to indicate an inescapable attraction, yet it is a strange example of animal behavior that continues to confuse people today. Scientists have raised a number of theories over the years to explain why. One holds that insects flying at night are following their nature to fly toward the brightest spot in their field of vision, which they mistake for the sky. Another suggests that insects are trying to warm themselves with the heat produced by the light. The most popular theory, though, is that insects are confusing lights with the moon or other celestial bodies (天体) that they normally use to navigate (导航).

To find out the real reason, the team carried out a first set of experiments in an insect flight area. The researchers used eight high-speed infrared (红外线) cameras equipped with motion-capture technologies to track 30 insects from three moth and two dragonfly species. They also flew lab-raised insects from six different insect orders that were too small for motion-capture technology, including fruit flies and honeybees, to make sure different insects all showed similar responses to light. Working with co-author Pablo Allen of the Council on International Educational Exchange in Monteverde, Costa Rica, the researchers put heavy cameras, lights and tripods in two field sites to gather behavioral data from insects in the wild.

The team was able to confirm that insects were not beelining to the light but rather circling it as they tilted (倾斜) in an attempt to turn their backs toward it. This behavior, known as a “dorsal light response”, normally helps insects to remain in an unchanging path of flight that is properly lined to the horizon (地平线). Artificial light that arrives from a point source causes them to fly in unpredictable patterns as they try to turn their backs to what they are mistaking for the sky.

Now research might have finally solved the mystery mentioned first: artificial light confuses insects’ ability to turn themselves to the horizon, confusing their sense of what is up and down and causing them to fly in circles.

4 . “Leftover roast potatoes? There’s no such thing!” shouted people on social media when I shared a suggestion for using up remaining potatoes. This response is common whenever I propose ideas for ingredients (食材) considered “delicious” or a treat: wine, Easter eggs and cream. One person’s trash is another person’s treasure, and all that—but the way we handle leftovers has to change. Because of my work creating recipes, I am constantly dealing with leftover food. I live alone, work from home and enjoy the challenge of transforming leftovers into new culinary delights.

During lockdown, I witnessed in people a growing understanding of having to make do with what was already in the cupboards, fridge and freezer. This led to an increasing confidence around making substitutions and understanding food-safety issues (such as the difference between “best before” and “use by”). I learned everything I know about food safety during my professional life.

While sharing food with neighbors, friends and the wider community is one way to deal with remaining ingredients, managing random bits and open packets requires a different approach. So in May 2022, I started a series on social media called Rollover Leftovers, showcasing daily short videos of my home cooking. Simple concepts such as refreshing rock-hard bread, freezing leftover chips or creating a “clear out the fridge” tray bake gained millions of views — a much bigger audience than I would expect for anything using tricky methods or fancy ingredients.

Use your imagination and trust yourself, and you’ll discover that leftovers can be a joy, not a chore. And if you find you have the leftovers of a great big turkey but are fed up with the sight of it, or you have more cranberry sauce than you could possibly eat alone, why not try joining forces with neighbors or friends? Not so much bring a bottle as bring a loaf, because a post-Christmas leftovers sandwich is truly the best bite of the year. Isn’t it?
