1 . In July 2021, astronauts on board the International Space Station (ISS) planted pepper seeds as part of an experiment to test which plants could be successfully grown in space. The peppers were harvested four months later, and the team celebrated with a party and taste test.
For astronauts living mostly off prepackaged foods for months at a time on the ISS, fresh and flavourful produce is welcomed. With long missions to the Moon and Mars in focus, NASA is working to find sustainable ways for astronauts to enjoy fresh foods, which will add key nutrients to their diets and improve their state of mind.
Astronauts have grown radishes, zinnias and a variety of lettuces on board the ISS before, but this is the first time they grew peppers, which posed a new challenge, reports Elizabeth Howell for Space. com.
Biologists at the Kennedy Space Centre spent two years picking the perfect pepper. They wanted to try peppers because they’re a great source of vitamins and nutrients, and they can be eaten raw or cooked. Plus, peppers are fairly low maintenance to grow.
In June, a carrier delivered supplies to the ISS along with a package of 48 pepper seeds. Astronauts on board planted the seeds in a microwave oven-sized growing container. The conditions in it—such as lighting, watering and air circulation—were controlled by a crew based at the Kennedy Space Centre. On board, the astronauts collected data and offered feedback on the flavour of the peppers.
“This is important because the food astronauts eat needs to be as good as the rest of their equipment,” LaShelle Spencer, a plant scientist at NASA, said over the summer. “To successfully send people to Mars and bring them back to Earth, we will not only require the most nutritious foods, but the best tasting ones as well.”

3 . Public service advertising is designed to inform the public on issues that are frequently considered to be in the general best interests of the community at large. Typically, it reflects a political viewpoint, philosophical theory, religious concept or humanitarian notion (人道主义观念). It is also commonly referred to as a public service announcement (PSA) or a community service announcement (CSA). The ads are usually broadcast on radio or television, but may also appear in newspapers or magazines. They are common in industrialized countries throughout the world.
PSAs are commonly aimed at changing public attitudes by raising awareness about particular issues. Health, conservation and safety themes are prevalent in many PSAs. The public service advertising campaigns are often sponsored (赞助) by trade associations, civic (市政的) organizations, non-profit institutions or religious groups.
Most public service advertising involves joint efforts of the private and public sectors (部门). Non-profit groups and government agencies commonly team up with private mass media, promotion and advertising firms to produce spots for radio, television and print media. Most commonly, the non-profit agency creates the message and an advertising firm develops the campaign, polishes it to meet industry standards and plans its distribution, all free of charge. Television and radio stations usually broadcast these ads at no charge, and magazines and newspapers usually publish them for free as well.
In recent years, it has become commonplace for U. S. television stations to feature public service advertising spots immediately following a broadcast that has focused on an issue considered sensitive and of concern to many members of the general public. These PSA broadcasts generally offer addresses, Web sites and toll-free telephone numbers for information sources. Some of the topics focused on in the PSAs have included child abuse, AIDS and civil rights.

4 . Camps Serving Both Boys and Girls
Camps that serve both boys and girls traditionally offer programmes that separate girls and boys while at camp, yet bring them together for some activities or meals.
Cheley Colorado Camp Founded in 1921
The Cheley Colorado Camp serves young people from throughout the U. S. and several other countries. Located in and around the Estes Park Valley and surrounded by breathtaking mountain views and forests, Cheley Camp serves boys and girls, divided by gender (性别) and age group, starting at age nine years old. Campers have the opportunity to experience unforgettable fun activities, mountain biking, river rafting, horseback riding, hiking, and backpacking. Through these activities, campers learn team-building, cooperation and leadership skills and self-confidence. When the day is done, campers have the opportunity to gather around the evening campfire.
Camp Killooleet Founded in 1927
Camp Killooleet serves boys and girls who are 9—14 years of age. Camp Killooleet is located along the edge of the Green Mountain National Forest in Hancock Vermont. The owners say that nearly all the campers return to Camp Killooleet each year until they reach the age limit. Children are housed in small groups of the same gender and experience the beauty of the nearly 300 acres and private lake. In addition to bicycling at the flat campus, children can explore local nature sites, canoeing in the Adirondacks, caving and rock-climbing. Children can also choose a wide variety of sports such as basketball, soccer, horseback riding and so on.
Camp Weequahic Founded in 1953
Lying just two hours northwest of NYC and three hours north of Philadelphia, Camp Weequahic offers a traditional camping experience for campers aged 7—13. Parents and children may choose the three-week sleep-away option or can opt for the “Super Six” week camping experience. Whichever option your family chooses, Camp Weequahic features continuous fun and learning experiences for your children. In addition to traditional types of camping activities, campers can also opt for specialty camps in the arts, sports or adventure. Campers also enjoy a variety of water activities and venture out on trips to nearby venues.

5 . Almost everybody knows that sports stars can be role models to high school students. But what many do not know is the effects they may have on our kids. Researchers now have made some important findings. The first effect that professional athletes can have on high schoolers is improving their personal character.
A fine example comes from a study through the Changing-Lives programme in the UK. The authors were able to conclude “athlete mentors (导师) are able to inspire kids, change their attitudes and help improve futures”. The study looked at mentor-pupil relationships in different middle and high schools. The mentors are successful sports people and the pupils are 2,701 students from 222 schools.
The findings were able to support the popular belief that sports stars can act as role models to inspire young people. The mentors visited students three times over the six-month period. During the visits, the mentors and pupils told each other about their own difficult problems that they had to face and deal with. This was a way for the pupils to see that the athletes were once just like them, and they too could solve their difficulties and achieve great things.
Another major effect is that professional athletes as role models can influence young people’s future aspirations (愿望). In a study carried out in the USA, 662 ninth-grade students (who began their first year of high school), were surveyed about their career aspirations. When students have a career aspiration, the researchers found, it may be determined by sources such as who their role models are.
In the study, students from every background were asked about their career goals, and whom they chose as their role models. The results included 41% of black young men, 25% of Latino young men, 7% of young black women, 5% of Latino young white women; all had role models of sport professional athlete.

6 . For the last 8 years, about 200 residents of Strunino, a small town in Russia’s Vladimir Oblast region have not had to worry about buying bread, thanks to the generosity of a local grocery store owner who has been giving it away for free.
Mamoud Shavershyan came to Russia, from Armenia, 25 years ago. He worked as an engineer, before setting up his own business. But everything changed one day, 8 years ago when sitting behind the counter, Mamoud saw an old lady counting dozens of coins to pay for a couple of loaves of bread. He found it embarrassing for the old lady and ended up giving her the bread for free. That day, he made the decision to print coupons (优惠券) that the elderly in Strunino could exchange for white or black bread at his store. To make sure that people knew about his offer, he advertised it in a local paper.
But that was only the beginning. Soon, Mamoud continued his generous offer to people with disabilities, large families with low income, and the generally poor. News spread like wildfire, and soon poor people from neighbouring villages started coming by his shop to receive coupons. Today, the “Eric” grocery store in Strunino gives away around 2,000 loaves of white bread and 1,000 loaves of black bread every month. They also regularly donate gingerbread to local kindergartens, and to coupon holders during holidays.
The kindhearted Armenian says that he just wants those less fortunate than him to have a better life. “Local authorities don’t care about my initiative (计划,措施),” Mamoud says. “They have never acknowledged my work, never offered thanks, but I didn’t do it for that. I just want the people around me to have an untroubled life.”

7 . A group of researchers has developed a new material which is as soft as cotton but as strong as Kevlar and as conductive as many metals. It can be worn and washed like normal clothing and could eventually turn athletic clothes into smart “wearables”.
The so-called “carbon nanotube(纳米管)threads” work similarly to the wires in an EKG (心电图)monitoring device, which measures heart rhythms to detect heart conditions. But instead of having to be patched(贴上)onto the skin, they can be sewn into a T-shirt and worn like normal athletic clothes, according to a new study from researches at a Rice University Brown School of Engineering lab. And unlike wires. they say the threads can comfortably move with the wearer. and be washed, stretched and worn repeatedly without breaking down.
The Rice University lab first developed carbon nanotube fiber in 2013, and has studied its use in medical operations, such as in cochlear(耳蜗的) implants for hearing loss and to repair damaged hearts. But at the time, the original filaments (细丝) were too thin to be used by a standard sewing machine.
For this latest one, researchers worked with a rope-maker to weave the filaments together into a material similar to regular sewing thread that could be sewn into athletic clothes. The resulting “smart” shirt provides “soft, wearable, dry sensors for continuous” EKG monitoring, the study states.
Though likely a long way off from going into production for consumers. the material could eventually help replace heavy EKG monitors in medical settings and heart rate monitoring watches. With some changes, clothes with these fibers could eventually be able to track other vital signs, according to the researchers.
“You just don’t find soft, flexible, thread-like materials that are comfortable to the touch, that you can work with, that you can build a bridge or you can build a power line out of , but you can also run it through a sewing machine. ” said Oliver Dewy, a member of the research team. “Nothing else behaves like this. ”

9 . When I was a teenager, I knew nothing about mental health and I didn’t care about mental health. Why would I? Like my dad always used to say, “If it isn’t broke, don’t fix it!”
But, unfortunately my mental health did “break”. Aged 17 I developed anorexia(神经厌食症). I didn’t realise at the time. When I was 23, I was found severely clinically anorexic. I had fast-tracked treatment at The Maudsley Hospital and went through 2.5 years of treatment. People are always interested to know what helped me recover. Actually, it was simple: comedy.
I’m a professional talk show actor. Comedy, for me, began as a hobby and has unbelievably progressed into a job. One of the things that initially held my attention about talk show is how it plays with pain. Humour became a way of understanding things, then a way of explaining them. Now it’s become a way of helping other people.
The combination of being told to speak out about mental health and writing comedies to play jokes on myself, actually turned into the best type of treatment I could ever have had. Nothing has ever really helped normalise a thought or feeling quite like a joke that makes people openly say, “Me too!”
That’s why I’ve come up with a six-week comedy course aimed at people with mental health difficulties. It builds lasting friendships, fights against loneliness and normalises conversations around mental health; when audiences are laughing, they have to be listening, and when they’re listening, they can learn. This unique opportunity enables comedy to reach people in a completely different way to all the sob stories, shocking statistics and dry documentaries (纪录片) about mental illness, inspiring with positivity rather than turning to negativity.
Talk show was a must to my recovery. So, I want to pay that forward and show other people that your mental health doesn’t have to be “broke” before you can “fix it”.

10 . Imagine you’re moving to a new country on the other side of the world. Besides the geographical and cultural changes, you will find a key difference will be the language. But will your pets notice the difference? It was a question that nagged at Laura Cuaya,a brain researcher at the Neuroethology of Communication Lab at Eötvös Loránd University in Budapest.
Cuaya set out to find the answer. She and her colleagues designed an experiment with 18 volunteer dogs—including her two Border Collies, Kun Kun and Odin—to see if they could differentiate(区分) between two languages. Kun Kun and Odín were used to hearing Spanish;the other dogs Hungarian. The dogs sat still within an MRI machine, while listening to an adaptation from the story The Little Prince. They heard one version in Spanish,and another in Hungarian.
Then the scientists analyzed the dogs’ brain activity and they found a different activity pattern for one language versus(与……相比)the other. Andics, who leads the lab where the study took place, said, “The finding suggests that dogs’ brain can differentiate between these two languages. In terms of brain imaging studies, this study is the very first one which showed that a non-human species brain can discriminate between languages. ” They also found that older dogs brains’ showed bigger differences in brain activity between the two languages,perhaps because older dogs have more experience listening to human language.
Amritha Mallikarjun, who wasn’t involved in this study but has been working on similar research about dogs and language, said, “It is a very exciting study because it shows that the ability to grasp the sounds and rhythms of a familiar language is something accessible to non-humans.”“And while this work relied on brain imaging,” Mallikarjun said, “it would be worth investigating whether dogs could differentiate between languages in behavioural studies, too.”
