Students in Andrew's class travel 5 to 15 kilometers each day to attend his lessons. The daily4 reflects the broader barriers to5 in Zambia, where over 800,000 primary school-aged children are out of school.

Andrew6 to let these barriers limit the potential of the7 young learners who make the daily journey to his classroom. Drawing from local culture, he8 traditional games — like skipping rope. These9 helped children understand numbers and develop foundational skills in10 ways. At the same time, he11 support from the school administration and fellow teachers, even using his own funds to obtain essential teaching materials.12 to developing a sense of professionalism and13 among teachers, Andrew and his colleagues printed T-shirts decorated with "Catch-Up Program Teacher". It was a small but powerful14 that reinforced their identity as teachers dedicated to transforming learning outcomes.

One of his students15 Andrew's impact best: "My mother asked me why I go to school. I replied, to become just like my teacher when I grow up."

The researchers were exploring the advantages of scholarly culture. They were interested in an extra finding that some call the "radiation effect". "The radiation effect is a situation where children grow up around books, but they don't read books. But somehow books benefit them, even though they don't read them as much as their parents wish them to," said Joanna Sikora, a scientist in Australia. Joanna and her workmates studied information collected between 2015 and 2019 by the Organization for Economic Development. The survey tested the literacy, numeracy (计算能力) and technological abilities of more than 160,000 adults from 31 countries. And it included a question about how many books participants (参加者) had in their homes during adolescence (青春期). "What we were able to make clear was that people growing up around books had better literacy, numeracy and technological problem-solving skills than people who had fewer books growing up but had similar education levels, similar jobs, and even similar adult habits in connection with reading or working at numeracy-improving activities," she said.

In fact, teens who only made it through high school but were raised in a bookish environment did as well in adulthood as college graduates who grew up in a house without books. Now, how might a simple display lead to intellectual (智力的) improvement? "If we grow up in a house, in a home where parents enjoy books, where books are given as birthday presents and valued, this is something that becomes a wealth of knowledge and gives us this lifelong driving force (驱动力) to always come close to books and read more than we would."

So keep shelves filled with books. Your kids will not only be thankful, they'll be more likely to be able to spell "thankful" correctly as well.

The team observed over 105,000 female and male health professionals in midlife for 30 years. Participants regularly completed detailed dietary questionnaires. The researchers scored these answers based on eight different healthy dietary patterns. These patterns, such as the Mediterranean diet or the DASH diet, generally encourage high intakes of fruits, vegetables, whole grains, and healthy fats, while limiting red and processed meats. They also carefully examined the amount of ultra-processed foods participants consumed.

The results are promising. A total of 9.3% of the population aged healthily. Overall, those who stuck to any of these healthy dietary patterns were more likely to age well. The top performer was the AHEI diet. People with high scores were much more likely to live past 70 in good health than those with low scores. Another strong option was the PHDI, which emphasizes plant-based foods while considering planetary health. In contrast, eating too much processed meat and sugary drinks lowered the chances of healthy aging.

The researchers emphasize that there is no "one-size-fits-all" diet. Healthy diets can be adapted to fit individual needs and preferences. The main goal is to eat mostly plant-based foods with a moderate inclusion of healthy animal products. This flexibility helps people maintain an independent and active quality of life as they age, which is a priority for both individuals and public health.

However, the study has some limitations. The participants were all health professionals, meaning their socioeconomic status and education levels might be higher than average. To apply the results more widely, future studies should repeat the research in populations with more diverse backgrounds.

Humans have long collected objects to remember experiences. With the rise of industrialization and tourism, souvenirs became more common. Souvenirs bring back happy memories, serving as a simple way to say, "I was there." "At the heart of our actions is a desire to feel heard, seen and connected," explains Madarkal, a professor in India.

Travellers today are more aware of their impact on local community, but the problems caused by travel souvenirs are often overlooked. In a 2022 Australian report, up to 75% of souvenirs marketed as "local" are made overseas. Real goods are expensive due to time-consuming labour involved, so some shops sell cheap fakes (假货) with most customers giving little regard to their origins. While buying fakes may seem to support local sellers, it often minimizes the profit of the traditional handicrafts, creating a negative cycle.

So, how can you buy meaningful souvenirs? "Be curious... it's not just about buying or choosing carefully, it's about rejecting and explaining why," said Madarkal. Asking where an item comes from and how it is made is a good first step. Choosing unique designs over mass-produced goods at fair-trade markets helps support local communities. Intentions also matter, as souvenirs should be chosen for personal meaning rather than habit. And souvenirs don't always have to be objects — journals or skills gained can become lasting reminders.

Ultimately, there's no universal rule for a "meaningful" souvenir. But next time you're grabbing a quick airport souvenir, pause and reflect.

One Central Park (Sydney, Australia)

A park at the foot of the building literally continues up the structure, as vegetation of 250 species of Australian plants and flowers cover One Central Park. An architectural website says it has 25% less energy consumption compared with a conventional building of its size.

Shanghai Tower (Shanghai, China)

Shanghai Tower has a transparent second skin wrapped around the building which creates a zone of captured air that serves as natural ventilation (通风), reducing energy costs. Besides, 270 wind devices incorporated into the right side power its outside lights.

Marco Polo Tower (Hamburg, Germany)

Each floor of Marco Polo Tower is turned a few degrees away from the one below, around an axis (轴线). This allows for recessed (嵌入式) buildings that protect residents from direct sun. This tower also includes many other green features. There is a heat exchanger on the roof that turns warm air into a cooling system. And the natural ventilation can make residents sleep soundly without being disrupted by outside noise.

Torre Reforma (Mexico City, Mexico)

Torre Reforma rises to 807 feet and stands tall on energy-saving measures, too. The tower's slimness maximizes the amount of natural light let in, which in turn cuts down on the need for electric lights. And when the weather permits, controls can automatically open windows to let air in.

Uber Eats pilots (试行) reusable container scheme

From today (Tuesday 18 April, 2023) Uber Eats customers in Central London will be given the option to order their takeaway in reusable containers and easily return them in an attempt (address) single use packaging.

(Bring) together various businesses (企业), the project will test and measure how localized doorstep at-home collections of reusable packaging can increase the adoption rate of a reuse system and improve convenience. The system has been developed to make as easy and convenient as possible for people to take part. When placing their orders, Uber Eats customers can choose to receive their food in reusable packaging. Once they've enjoyed their meals, they need to do is to scan a QR code (二维码), select a day for collection, give the containers a simple rinse (冲洗) and await collection. All collections are low or no emissions, (make) by deliverymen using bikes, electric cars or vans.

The trial will run for six months and will be managed by Again, which operates a network of packaging cleaning facilities the reusable packaging will be cleaned and processed before being returned to the restaurants. Various promotions (test) throughout the trial to measure opt-in rate and return rate. "This pilot aims to make reusable packing (access) for customers and restaurants alike," says Matthew Price, Uber Eats General Manager. "By integrating the reuse option a delivery app used by many households and by offering doorstep collections, we hope to see a significant increase in the use of reusable takeaway packaging. The trial will help create better understanding of what works and what doesn't at a local level, and hopefully lead to wider roll out of this reuse system across more businesses and areas."

We've all heard the saying "The family that plays together stays together." Enjoying quality family time is important and working out together could be the perfect solution. It's never too early to introduce healthy lifestyle choices, whether you leave the car at home and walk to school or enjoy a family cycle at the weekend.Here are some tips when it comes to enjoying free time and working out as a family.

Set rewards for achievements. Taking the kids to the park is such a fun and easy thing to do. Try setting them tasks. If they manage to do all the tasks, allow them a certain amount of TV or gaming time if that's what they like to do!

Find a hobby they enjoy. One of the most important things is to find a healthy hobby that they love.If they enjoy it, encourage and support them to build up their confidence.

Find exercise friends. Perhaps there's a family nearby with kids the same age. See if they would like to exercise together.Besides, it sets a level of cooperation where you can't let the other family down. It's also a good excuse for a coffee and a chat with the mum or dad afterwards.

It can be easy to want your child to be the best but it's all about them having fun with fitness. Support them, but don't pressure them too much, or it might backfire!

A. This will motivate everyone.

B. Don't be a competitive Mum or Dad!

C. Support the kids with encouragement.

D. Avoid making the reward about food or drink!

E. They're more likely to be fit and healthy later in life.

F. Ask them what they fancy giving a try and, within reason, let them!

G. Working out together as a family is one of the most beneficial things you can do.

"Liming can be a carbon source or sink. Practical tests suggest this is a pretty efficient carbon sink," says Noah Planavsky at Yale University. This could offer new motivation to spread more limestone on the world's farms — but liming won't have this effect everywhere.

Currently, most crushed limestone spread on fields is counted as an emission source because its carbon is released as CO₂ when it dissolves (溶解) in acidic soil. However, Tim Jesper Suhrhoff, also at Yale, argues this accounting is incomplete. Soils are very acidic due to fertiliser use and fossil-fuel pollution, and other alkaline (碱性的) minerals in soil will release carbon even without limestone. He says added acidity, not liming, is to blame for emissions.

To accurately assess liming's emissions, researchers should compare CO₂ release and uptake with and without liming. Suhrhoff, Planavsky and colleagues studied the Mississippi river basin, calculating the net carbon effect of liming between 1900 and 2015. They used geochemical models and data on soil-acidity changes from fertiliser and liming, and compared results with Mississippi alkalinity measurements. Their new approach showed liming in this region removed about 300 to 400 million tonnes of CO₂ instead of generating emissions.

Planavsky says liming could be paired with spreading crushed volcanic rocks on farms to remove more CO₂. Wolfram Buss at the Australian National University warns that what worked in the Mississippi may not work everywhere, as liming can be a net CO₂ source in some systems.

The next step is to identify regions needing liming most. Planavsky says, "It could promote practices aiding crop yields and removing billions of tonnes of CO₂, helping low-income farmers who can't afford optimal liming."
