1 . Plastic is everywhere, from the Arctic ice to vital organs in the human body. In fact, previous estimates suggest that the average person swallows a credit card-worth of microscopic plastic particles(颗粒) every week. But new research shows that this could actually be an understatement.
Microplastics are plastics smaller than 5 millimeters, found in industrial waste, beauty products, and formed during the degradation of larger plastic pieces. Over time, they break down into even smaller nanoplastics. These tiny particles can pass through our intestines and lungs into our bloodstreams, reaching vital organs like the heart and brain.
While the idea of eating plastic is unsettling in itself, the major concern here is that these plastic particles contain chemicals that can interrupt our body’s natural release of hormones, potentially increasing our risk of reproductive disorders and certain cancers. They can also carry toxins(毒素) on their surface like heavy metals.
In the past, researchers have shown bottled water can contain tens of thousands of identifiable plastic fragments in a single container. However, until recently, only the larger microplastics were detectable with available measuring tools, leaving the area of nanoplastics largely a mystery.
Using Raman microscopy (显微镜学), capable of detecting particles down to the size of a flu virus, the team measured an average of 240, 000 particles of plastic per liter of bottled water, 90 percent of which were nanoplastics, a revelation 10 to 100 times larger than previous estimates.
These plastics likely originate from the bottle material, filters used to “purify” the water, and the source water itself. “It is not totally unexpected to find so much of this stuff, ” the study’s lead author, Columbia graduate student Naixin Qian, said in a statement. His team hopes to expand their research into tap water and other water sources to better inform our exposure to these potentially dangerous particles. “The idea is that the smaller things get, the more of them I reveal, ” he added.

3 . If you have a thought in mind that you can achieve the same goal within less amount of time and hard work by cheating to achieve success, then you shall feel bad later in future. You may have achieved a goal but you choose a wrong path. So, always remember that the path you choose in your life chooses your destination and then you shall not have an option to change it.
It is good to fail though it may take you to terrible feelings of life but in return, you will learn many things that life offers. The struggle is true but after that, the sweet of the fruit will build up your confidence to face any kinds of problem in the future. But if you prefer cheating, then you shall always live in fright.
Honour is like a coat, which you can wear confidently. If you cheat to achieve a goal, then you cannot hide it. Billy was lazy in hard work and used to delay all his work. He always thought of taking a fake degree to enter a big company. When the company CEO asked him to write a program for a certain topic, then he was quite shocked as he was unable to do the work, because he had no knowledge on the programming language and had faked his certificate.
Honour teaches you how to be disciplined. Being well-educated people, we should know what is good for us. It is always good to fail because at the end of the day, you will learn something new that will help you grow much stronger rather than cheating to achieve success, which will make you regret sooner or later.
All in all, success can be achieved via shortcuts but honour can never be. It’s better to live everyday with honour than to cheat.

4 . People duck responsibility for reasons ranging from simple laziness or a fear of failure, through to a sense of feeling frightened by the scale of a problem or a situation. Whatever the reason, if people fail to take responsibility, they’ll fail in their jobs, they’ll fail their teams, and they’ll fail to grow as individuals. All of this makes it important to address the issue.
Signs of not being responsible
There are several signs to watch out for. These include:
Lacking interest in their work, and in the well-being of the team
Blaming others for mistakes and failures
Missing deadlines
Avoiding challenging tasks and projects, and not taking risks
Regularly complaining about unfair treatment by team leaders and members and engaging in self-pity
Avoiding being dependent on others for work, advice and instructions
Lacking trust in team members and leaders
Ways to encourage responsibility
Start by talking
Your first step is to talk to the individuals concerned. Are there circumstances that are contributing to the situation, or problems that you can deal with?
Communicate roles, responsibilities and objectives
Your people need to know clearly what their roles and responsibilities are. Ensure that you have an up-to-date job description for each team member, and be as detailed as possible about every responsibility that they have.
Re-engage people
Your people will be more engaged if their work is supported with their values. Talk to them to find out what they are. Then, illustrate how their daily tasks and responsibilities go with those values.
Give plenty of praise
Finally, be sure to give your people plenty of praise when they do take responsibility. And help them improve by providing them with regular, effective and fair feedback.

When I was in middle school, my family moved to Seattle, where my parents started their new business — a small grocery store downstairs my house. As a girl of shy and reserved nature, I had to take a fresh start to fit into the sophisticated city life.
One sunny day, my school announced an exciting event, a talent show for the local food bank. Students were encouraged to showcase their unique talents in front of the public in the city hall on National Day. A buzz of excitement fed the school as everyone began preparing for the big day. Deep down, I felt a spark of curiosity and a desire to participate. However, my self-doubt held me back, “I don’t have any special skills to share.”
Days turned into weeks, and the talent show drew closer. I couldn’t shake the upsetting feeling until one day, Emma, one of the most popular girls in my class, came to me while I was helping in the grocery store after class. “How about singing together in the talent show?” She grinned, “I heard you singing a tune, along the way back home. I can’t help following you here.” Gosh, I couldn’t believe my ears. Emma, with personality and popularity, acknowledged my little talent. Since Emma had the world’s prettiest voice, I felt like being favoured by fortune.
“You two? The talent show for the food bank?” My mum bent towards us and her face lit up. “A big occasion.” Then a light bulb seemed to go in her head. “Why not practise right now upstairs? I bet you’ll be a perfect match.” Winking at us, she seemed to know we were thinking alike.
Emma and I embarked on rehearsing almost every single day after school. We brainstormed, exchanged ideas and rehearsed the scene. As the days rolled by, I was feeling pretty good about our act. But the day before the performance, Emma called that she had an acute stomachache and was not in any shape to perform.

A few days before New Year 1944, Patricia Krueger received a telegram from the U. S. Army. She hoped it would contain a belated birthday greeting from her husband, an army flight engineer, Charles Krueger, whom she had not heard from for 2 weeks. Instead, the message said he wasn’t coming home: His B-29 had been lost and he was later declared MIA (missing in action). Their son, John Krueger from Middleton, Wisconsin, is still in tears when he recounts this story.
Decades later, the military continues to work to bring back the remains of soldiers like Charles Krueger. The job of finding them falls to DPAA (Defense POW/ MIA Accounting Agency), created in 2015 after critics charged that the previous MIA search process was slow, and behind on innovations in science and technology. Between 1973 and 2014, the remains of only 1,849 missing service member s were returned to their families; in 2021, the agency accounted for the remains of 141 MIAs; according to DPAA figures.
To accelerate the work, Congress gave DPAA the authority to develop public-private partnerships with scientists and groups outside the government. “Teaming up with academic scientists introduces new ways of thinking,” says military historian Michael Dolski. “Working with partners allows us to tap into their technologies and capabilities in ways that we just can’t maintain.”
For scientists, the work is more than technically satisfying. “It’s the most rewarding aspect of my career,” says Mires, a scientist working with the agency. “In other archaeology sites I’ve worked on, the history is remote,” he says. “Here, you’re doing something not for a thing, but for a person, and all the people they touched.”

With a wide smile on her face, 15-year-old Sirin eagerly rushed to her mom to show off her new painting. But Mom raised her eyebrows with eyes wide open, and spoke impatiently, “No time, baby. Right now I am busy with an important talk. Just wait for some time, OK?”
Holding her oil painting, she frowned (皱眉),and then searched for her dad. “Dad, see what I have done,” Sirin exclaimed cheerfully. Her dad turned around while adjusting his tie, grinned at her, and showed his thumbs up!
Immediately, Sirin replied angrily, “Dad, you haven’t seen it yet.”
He smiled at her saying, “No time, baby. I will see it later.” He just patted her back lovingly, kissed her forehead, and rushed for his office.
She was not a kid to be pleased with simple gesture or smile. She stood there for a few seconds, and then stormed off to her own bedroom. Hot air was blowing from her nostrils (鼻孔) ; her face turned into apple red. She threw the painting on the table, slammed the door and threw herself on her bed.
“Why is everybody so busy?” She recalled thousands of incidents that hurt her in preschool, middle school and even in high school too! She assumed at least her own family members would give some values to her thoughts, but they were no exception. Unconsciously, her eyes were filled with tears.
The knocking sound on the door put a sudden stop to her thought. Her mom was calling her for dinner. Sirin deliberately (故意地) came late to join them. She kept silent and didn’t look at anyone, scratching the table mat with her nail. Her mom was puzzled at the unusual behavior. Suddenly the morning incident came to mind. Softly, she asked, “ Honey, did I do anything wrong? ”

Is It Worth Buying Organic Food?
Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious (有营养的) and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.
The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. “We did not find strong evidence that organic food is more nutritious or healthier,” says Dr. Crystal Smith-Spangler from Stanford. “So consumers shouldn’t assume that one type of food has a lower risk or is safer.”
For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.
While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.
Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The U.S. Department of Agriculture (USDA) states that “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.
