One in three UK consumers throw away food just because it reaches the use-by date, but 60% of the £12.5 billion-worth of food we throw away each year is safe to eat.

The researchers, whose findings were published in ACS Sensors, say the sensors could also eventually replace the use-by date—a widely used indicator of being fresh and eatable.

The sensors cost two US cents each to make. Known as "paper-based electrical gas sensors (PEGS)", they detect spoilage gases like ammonia (a poisonous gas with a strong unpleasant smell) in meat and fish products. The information provided by the electronic nose is received by a smart phone, and then you can know whether the food is fresh and safe to eat.

The Imperial College London researchers who developed PEGS made the sensors by printing carbon electrodes onto a special type of paper. The materials are eco-friendly and harmless, so they don't damage the environment and are safe to use in food packaging. The sensors, combined with a tiny electronic system, then inform nearby mobile devices, which identify and understand the data about spoilage gases.

Lead author Dr Firat Guder of Imperial's Department of Bioengineering, said, "Although they're designed to keep us safe, use-by dates can lead to eatable food being thrown away. They don't always reflect its actual freshness. In fact, people often get sick from food-borne diseases due to poor storage, even when an item is within its use-by date."

"These sensors are cheap enough so we hope to see supermarkets using them within three years. Our goal is to use PEGS in food packaging to reduce unnecessary food waste."

The authors hope that PEGS could have applications beyond food processing, like sensing chemicals in agriculture, air quality, and detecting disease markers in breath like those involved in kidney disease.

Another prediction on the Internet is that data transmission (传输) speed will increase globally. According to Akamai Technologies, the average global data transmission speed in late 2019 was 26.7 megabits per second. Compare that to the record for data transmission speed set by Bell Labs: 100 billion megabits per second. At that speed, you could transmit 400 DVDs worth of data every second. That's an enormous gap between what's currently possible and what's commercially available. But as time passes, the costs of producing super-high-speed networks will decrease.

In the future, people will live under the sea and the housing shortage will be solved. There will be lots of glass domes (穹状建筑物)under the sea, which allow people to look all around into the sea. Air will be provided via air pipes which lead to the open air. You can travel from one dome to another via a kind of submarine which will also be made of glass. The domes will be so beautiful and the view under the sea will be so impressive that many people will prefer to live under water, and less people will prefer to live on land. This will have a positive effect on the environment on land.

In the future we won't use oil or gas as energy any more. We will make use of sunlight, water and wind. Cars will run on water. Just fill your tank with water, and you can drive further than you could drive with the same amount of gasoline. Also, the exhaust won't be damaging to the environment, because it'll just be water vapour. So the water cycle won't change, we'll keep the same amount of water on the earth, and we won't run out of water. Also, all energy will be supplied by natural sources: sunlight, wind and water.

"Birdcage effect" means that when you get an item one day, you will prepare more things to match it. Weeks ago, I was in the company of friends engaged in shopping. One said that she wanted to buy a good writing pen to match the delicate notebook that her sister gave her, so that she would fall in love with taking notes on reading, and thus love reading, not just reading. I joked that she must have fallen for the "birdcage effect". But the friend said with a smile: "Why not use the ‘birdcage effect' instead?"

For the first time, I heard that the "birdcage effect" can be used in reverse (逆向). However, this can't help but remind me of middle school, and I seem to have used the "birdcage effect". Passing by a bookstore one day, I purchased a magazine and saw the call for contributions published in the magazine, so I started writing with eager hands, and then I fell in love with writing.

After shopping with my friends that time, I began to proceed to use the "birdcage effect". I bought a small fresh tablecloth to decorate my desk, and a beautiful notebook to record my inspiration. When everything was ready, I started writing again.

But how can we get rid of the "birdcage effect" in many things, and even use the "birdcage effect" in the opposite way? Various "birdcages" unavoidably appear in life, but we can distinguish them. If it is not in line with the actual situation, it is a "negative birdcage", then we must learn to stop losses in time and maintain a heart of abandonment and separation. If it is a "positive birdcage" that motivates us to develop upward, we can clarify our goals, shop or decorate appropriately, and motivate ourselves to move towards our goals. At this time, you will find that the "birdcage effect" is actually not so terrible!

In a small village at the foot of a towering mountain lived a young woman named Maya. She was always attracted by the mountain's beauty and often dreamed of reaching its top. Every day, she would look up at the peak (顶峰), imagining what it would be like to stand at the top and see the world from that height.

One sunny morning, Maya decided it was time to make her dream a reality. She packed a small bag with food, water, and warm clothes, and set off on her journey. As she climbed, the path became steeper and more challenging. Rocks tumbled under her feet, and the cold wind bit at her cheeks, but Maya pressed on, determined to reach the summit.

Halfway up the mountain, Maya met a group of experienced climbers who were going downhill. "Turn back," they warned. "You look like a new hand. The climb is too difficult for you. It's not worth the risk." For a moment, doubt flashed in Maya's mind. She felt tired, cold, and unsure if she could continue.

But then, Maya remembered why she had started the climb. She wanted to prove to herself that she was capable of achieving her dreams, no matter how difficult the journey. With renewed determination, she thanked the climbers for their concern but decided to continue.

As she climbed higher, the air grew thinner, and every step became a struggle. Maya's muscles ached, and her breathing became difficult, but she refused to give up. She knew that each step forward, no matter how small, brought her closer to her goal.

She thought about her village and how proud everyone would be if she succeeded. She imagined standing at the peak, feeling the wind on her face and looking down at the world below.

With these thoughts in mind, Maya pushed herself onward, one step at a time. She was tired and cold, but her heart was filled with determination. She knew she could make it, and nothing would stop her now.

The Shanghai Museum held a donation ceremony on Wednesday for artifacts (give) by a Chinese famous singer. The first batch (批) of donated items (include) 12 pieces of clothing from the past surprising netizens and earning praise.

The singer, born in 1967, is a well-known male singer in China. While he is known a singer, he is also a collector.

When he learned that the Shanghai Museum's upcoming Jiangnan Creations exhibition needed (exhibit) on Shanghai-style cheongsams (旗袍), he offered pieces from his collection of over 1,000 cheongsam dresses and donated them (fill) the gap (缺口).

After (care) selection, he picked ten cheongsams from his collection, were unique and classic. Additionally, upon learning that the museum needed more Qing Dynasty women's garments, he donated two Qing Dynasty shirts and jackets.

(former), his private collection was also displayed at the Wuhan Museum in Central China's Hubei Province. In 2023, to celebrate International Women's Day, the Wuhan Museum opened an exhibition on women's fashion on March 7. (use) over 70 pieces of old-fashioned calendar posters and cheongsams as mediums, the exhibition showcased the fashionable, intellectual, free-spirited charm of Chinese women during that period through digital display methods.

A study conducted by researchers from the UK's Wellcome Trust found that people who speak Chinese use both temporal lobes (颞叶) of their brain to understand the language. This is very different from English-language speakers who use only the left temporal lobe. Speakers of Chinese use intonation (语调) to tell between completely different meanings of particular words, which needs stronger cognitive abilities.

Besides, the practice of handwriting, especially of Chinese characters, will aid the development of motor skills, learning shapes and letters and will keep the mind sharp. Through the use of Magnetic Resonance Imaging, researchers found that neural (神经的) activity in children who practiced printing letters by hand was more strengthened than those who just looked at them. Compared with English, mostly written in line and from left to right, Chinese characters have more complex in structure (复杂的结构). Their writing involves strokes (笔画) in all four directions: up, down, left, and right. The movement of the fingers and hand helps improve neural activity in the working, thinking, and memory of the brain of the learners.

Evidence also suggests that there is a connection between the learning of Chinese and math skills. Researchers from New Zealand noticed that Asian children educated in their own languages appear to have gained a greater understanding of math ideas than English-speaking children. During the natural learning process of Chinese, the student is learning basic math ideas. Math skills are included in character writing because it includes skills such as counting, grouping, ordering, and identifying similarities and differences.

While the research on the relationship between the learning of Chinese and cognition is not yet fully clear, there is good evidence to suggest that learning Chinese tones and characters represents an added challenge to language learning.
