2 . In 2016, Mark Raymond learned the hard way that life can change in a split second(一瞬间). One day, Raymond went boating with his friends. He jumped off the back of the boat and hit a sandbank, leading to a severe injury to his neck. He became paralyzed(瘫痪的)and spent months in the hospital receiving treatment. When he was allowed to leave the hospital, he realized that the hard part was just beginning. He still needed to exercise to recover his strength after finishing the outpatient(门诊病人)treatment.

However, when Raymond returned home, he realized there was a serious lack of accessible gyms or facilities that could help people with different abilities work out and improve their health in his community. The lack of them caused Raymond to take action. In 2018, he established the Split Second Foundation, a non-profit organization that provides treatment that takes up from where outpatient treatment left off.

“The Split Second Foundation has equipment for people who have different disabling conditions,” Raymond explained.“Our specially trained staff will evaluate(评估)disabled customers’ physical needs and limitations and then provide recovery, education, and ongoing fitness classes suitable for them. We’re able to push them in a recovery driven fitness environment to be their best selves.”

Raymond’s goal is to open more accessible gyms, not just in New Orleans where he lives. He hopes the Split Second Foundation can help even more people get their lives back after disastrous accidents. “People with disabilities should also be thought of as productive members of society,” said Raymond. “Anybody’s life can change in an instant due to some kind of injury or disabling condition, and we are providing what’s next.”

When Raymond couldn’t find the services he needed, he made some for himself and others. This is the sort of cleverness we love to see in the world.

4 . The Power of Insensitivity

Highly sensitive(敏感的)person, or HSP, is a term invented by psychologist Elaine Aron. HSPs can come with many challenges. They may find it hard to adapt to new surroundings, and easily become uncomfortable in response to certain feelings or others’ opinions.     1    

The power of insensitivity can be explained as “slow power”. Usually, people connect “insensitivity” with something bad, but indeed, it stresses the ability to keep doing something difficult without complaining.     2     It is not a weakness but an approach to winning a better life.

    3     Knowing yourself is difficult, and knowing yourself correctly is undoubtedly an excellent ability. The successful people clearly know where their strengths are, what they can do and what direction to go.

There are some ways to practice “insensitivity”: Don’t pay too much attention to the ups and downs of life at the moment.     4     Don’t get involved in other people’s lives and don’t let others affect yours. Regarding relationships, learn to view problems as two parts: One part is what you need to face and solve. The other part is the responsibility of others, which is not your business.

Everyone can gain the ability to be insensitive.     5     And the world will also be a better one if we focus on major goals and stay insensitive to something else.

6 . Have you ever imagined an insect-inspired robot, which weighs less than a gram, could one day help out in surgery (外科手术)?

Scientists have designed this small, “insect-bot” called mCLARI that can control and even change its body shape as it travels in different environments to fit through gaps. It’s 2 centimeters long, weighs less than 0.97 grams and can travel at a speed of 6 centimeters per second.It’s the smaller, faster replacement to CLARI, which was designed by the same team.

“Because of the robot’s small size and ability to change shape, we expect usage of this technology in four important areas,” the lead author Kaushik Jayaram said. These include disaster (灾害) response , check on high-value objects, environmental monitoring and medical treatment.

“In the long term, we hope such robots will be used more widely in moving through human bodies and performing surgeries that can’t be easily done at present,” Jayaram said. With mCLARI, Jayaram’s team is moving closer to creating robots that can fit in different environments—just like the insects they’re inspired by.

The mCLARI robot has four legs and can move in narrow spaces by changing between running forward and side-to-side and can use different speeds in human bodies. Its legs are joined to its body through joints (关节), which enables mCLARI to change its body shape based on the environment it is in. For example, its legs can be lengthened up to 50% in certain spaces.

As follow-up work, the scientists want to give mCLARI more power and sensing ability while helping the surgeries. “We are also excited about understanding the effect of shape change on improving functions of robots,” Jayaram said. “And this is sure a great one-step forward of the technology. The robot will have entered the market by 2025 and will bring greater benefits to mankind, especially in medical treatment.”

7 . Dusting is particularly annoying. Nearly two-thirds of household dust content comes from the outdoors, some of which may contain harmful chemicals. So, keeping your home as dust-free as possible is important to improve overall health.     1    ？

In general, you should dust your home’s most exposed surfaces on a weekly basis. This means items such as tables, shelves, beds, dressers, counter-tops and windows.     2    . Use microfiber or natural-fiber cloths that will pick up the dust.

Change your bed sheets weekly, as dust mites (螨) especially love bedding.     3    . Every three to six months, clean behind and under furniture, and wash your bedding.

Since so much dust comes in from the outdoors, you can cut down on the amount gathering in your home by keeping doors and windows closed as often as possible, and placing carpets on both sides of doors.     4    , changing them for a pair of slippers or private house shoes.

Get rid of odds and ends, which can easily attract dust, and be careful how you handle clothes. Since clothes both collects dust and sheds (掉落) fibers, regularly wash any clothes or don’t throw clothing on the ground.

When you’re getting ready to clean a room, always work from the top down.     5    , the dust on the highest surfaces will drift down to everything you’ve just cleaned.

8 . In the northernmost edge of Colombia sits the coastal town of Acandí. Access to the town is only by water or air; there is no road that leads there. The residents there are faced with the struggles of balancing livelihoods while protecting biodiversity.

In the past, traditional community fishing methods, passed down by the elders, focused on the reasonable fishing and management of resources. However, the introduction of large-scale trawling vessels(拖网渔船) decades ago gradually depleted the area’s fishing resources, leading to damage to marine(海洋的) life seriously.

Jesús Antonio Julio Cuestas, who serves in the region’s conservation and management of marine resources, stresses the bad impact of these developments and calls for new fishing techniques. “Fishing and conservation co-exist as long as we have good management practices and reasonable use of our fishing resources,” says Cuestas. He and other officials actively monitor fishing activities in Acandí. Each morning, they visit the fish markets to gather data on fishery resources—including prices and sizes—to monitor the state of the local fishing industry.

Along with Cuestas, the fishers work to reduce their impact on the marine ecosystem. By changing fishing methods and adopting new practices, they aim for a more balanced approach to fishing. “This year the local fishermen have not used the trawl net s that were causing the death of the leatherback sea turtles,” explains Cuestas proudly. Changes include the efforts of boats to protect the seagrass that serves as feeding grounds for marine life and an end to fishers throwing net s where turtles lay their eggs.

This marine reserve in Acandí, Cuestas believes, is their greatest treasure. He attaches great importance to working together with local residents to improve the quality of life while preserving the marine ecosystem. By doing so, he imagines a picture where individuals from the fishing community can pursue various careers, such as engineers or lawyers, proudly stating that they are the products of the fishing tradition in Acandí.

9 . How satisfied are you with your life? How good do you feel every day? Your answers to those two questions can show how happy you are.

It’s true that your happiness is partly affected by your genes.     1     According to experts, happiness is a choice. It’s something that you can develop with continuing practice. Following these tried-and-true tips can help you find happiness.

Don’t compare yourself to others. Everyone has different talents and abilities. It’s OK that you’re not like someone else. Comparison has been called “the thief of joy”. In addition, forgive yourself often.     2    .

    3     Yet much of what appears on social media is not real. Many people compare themselves with those images, resulting in feelings of discouragement.

Spending time with people you love and that love you is necessary for building strong connections and developing a sense of belonging. By devoting time and attention to those who matter most to you, you can create lasting memories, deepen understanding, and strengthen bonds with each other happily.

Nature helps to reduce stress. Exercise and put your health in the first place.     5     Just going on a walk can make a difference.

Stay aware of recent events. But don’t spend hours consuming news, which usually includes negative stories and events.

Since happiness is a choice, why not choose it? Life will look brighter filled with love and joy!

10 . Why do we talk the way we do? It might date back to when our ancestors left the jungle for the open plain. Between 5.3 million and 16 million years ago, Africa’s landscapes changed from thick, leafy forests to wide-open grasslands. This environmental change pushed our ancestors out of the trees and onto the ground. Along with all of the physical and behavioral changes this may have caused, researchers also believe it may have changed the way we speak.

“Open landscapes provide us with fewer objects to affect signal communication, meaning our voices can travel further compared with that in thick forests,” Charlotte Gannon, a researcher who studies language development, told Newsweek. “The move to these open spaces may have increased the effectiveness of our communication.”

By comparing the vocal calls of the orangutan (大猩猩) , Gannon and her team were able to establish how different calls could travel across different landscapes. In their study, the team played 487 calls from orangutans and measured their audibility (可听度) at set length over an overall distance of over 1,300 feet in the South African plain.

“Our results were surprising,” Gannon said, “The rule of sound spread suggests that lower-frequency (低频率) sounds (the grumphs) would have traveled further than higher-frequency sounds (the kiss squeaks). Our results actually found the opposite to this.” In these environmental settings, consonant (辅音)-like calls traveled a lot further than vowel (元音) -like calls. Actually, around 80 percent of consonant-based calls were audible at 1,300 feet, compared to only 20 percent of vowel-based calls.

Gannon said these results highlight the importance of studying living orangutan to learn about our species’ history. “We can view them as time machines that allow us to recreate key moments of our history so we can learn more about the development of our language,” Gannon said. “Despite their popularity in modern languages, consonants have often been forgotten when discussing speech development. Our research highlights not only their presence in ancient times but their importance to the development of language.”
