1 . In looking through your social media, there’s a good chance you’ve noticed pictures accompanied by texts. The pictures are likely made possible by a text-to-image program called DALL-E. For example, Twitter user posted a tweet with the text, “To be or not to be, rabbi holding avocado, marble sculpture.” Then a matching picture appears below.
The AI models come from Google’s Imagen software as well as OpenAI. a start-up backed by Microsoft. On its website, OpenAI calls DALL-E “a new Al system that can create realistic images and art from a description in natural language.” But most of what’s happening in this area is coming from a relatively small group of people sharing their pictures. That’s because Google and OpenAI have not made the technology broadly available to the public.
The text-to-picture services identify the most important parts of a user’s text and then guess the best way to picture those terms. There’s generally a text box, a button to start the generation process and an area below to display images. To indicate the source. Google and OpenAI add watermarks in the bottom right comer of images from DALL-E and Imagen.
Engineers trained the models on various collections of words and pictures from the web. OpenAI recognizes the potential for harm that could come from a model. To avoid the risk, employees removed violent content from training data, and there are filters（筛选）stopping DALL-E from producing images if users submit（提交）violent or illegal content.
Boris Dayma, a developer from Texas spelled out the problems in an explanation of their software. Despite the risks, Dhariwal, a research scientist at OpenAI, said it could open up creative opportunities for individuals and could help with commercial applications for dressing up websites. Results should continue to improve over time.

2 . Picture the scene: you’ve spent years working towards a very specific goal. You’ve put in countless hours of work and made many efforts along the way, but now that you’ve got there it doesn’t feel quite like you imagined. Instead of celebration, you feel emptiness, confusion and doubt.
Welcome to the anti-climax. The often-experienced but seldom-discussed downside of achieving life’s biggest milestones. Many of us work tirelessly towards our goals. We may spend our lives dreaming of the day we get married, publish our first hook or buy our first home. However, oftentimes, when we achieve these things it doesn’t feel quite as expected. In fact, the achievement of these goals feels a bit of a letdown.
So why do we often experience an anti-climax with big goals, even though we’re happy to achieve them? “An anti-climax can be an unexpected by-product of a milestone achievement. Usually, the more significant the milestone, the greater the anti-climax may be. The intensity（强度）of an anti-climax often relies on what we expect of this achievement.” says Rachel Vora. a psychotherapist（心理治疗师）.“The journey to achieving a milestone can he exciting and tiring in addition to giving us a sense of purpose and focus. Therefore, when this disappears overnight. we can often feel lost and confused, in spite of feeling proud of our achievement.
When this happens it can contribute to a mixture of emotions. We often falsely believe that we’ll feel completely different afterwards or that our feelings of low self-worth will disappear, but this is rarely the case. “Clients（客户）often present to me with an extremely great sense of ‘is this it?’ and ‘what now?’.” says Vora. “These feelings of confusion and disappointment, if let ignored, have the potential to cause clients to be in low spirits, or even worse.”

3 . As a college student in Boston, I formed the habit of buying used books. I enjoy the hunt, the good price and the unrecognized treasures. I find old textbooks, ex-bestsellers, and books on subjects I’ve never heard of and now must learn all about. I don’t search for rare books, first editions, or leather-bound editions but books that are worth reading.
Rereading, for me, is a pleasure during retirement. The theater and the concert hall become less appealing to me, along with crowds. Staying alone and reading books have become extremely important to me. Literature needs the flesh of experience to have its full effect. Different books offer me insights and ways of expressing that stuck in my mind as grains of sand in an oyster now shine like pearls. My taste in books improves with age.
While packing for a move, which occurs at intervals of five to seven years, I clear my shelves and pick my books. I abandon a few, later regret my decisions, and look for them again. Several years ago, I got rid of books related to my job-architecture. Some were design guides, reference books, product catalogs, and things that went out of date. Some were historical or centered on a period or an architect. These had given me many hours of pleasure. Will I ever open their covers again? Certainly. I held on to the red bulk of Sir Banister Fletcher’s A History of Architecture and books on Paris, Rome, and Boston.
I gave away drafting equipment and instruments. I threw out rolls and rolls of paper, and old drawings of projects completed long ago, some of which had even been damaged. This time, I stay put in a cottage that suits my status and I’ve moved on in spirit. No doubt I will acquire more used books and throw away more books as passions grow and fade, like feathers changing with the seasons.

4 . As more people move into their golden years, many families are welcoming their senior parents into their homes. While most seniors claim to prefer to age in their own homes, safety and health concerns don’t always make this possible.
If you are preparing to welcome a senior parent into your home, everyone will have an adjustment period. This type of move will have physical, emotional, and mental influences for the whole family. Here’re a few tips to help you open your heart and home to your senior parents.
You may be excited about having your senior parent move in, but that doesn’t mean they will share your enthusiasm. Being asked to move out of their own home can be very upsetting for your parents. So it’s important to be patient with them and allow them the time to adjust to their new environment.
It’s also important to give your parents a space of their own. Before you decide to bring a senior parent into your home, you need to consider if you have enough space for them.
Then, for adult children, offering a senior parent a safe home is a priority. Before moving, you will need to make some changes around your home to help your parents stay safe. For example, install grab bars in the bathroom, repair all stairways, add anti-slip mats to the kitchen and so on. And arm yourself with knowledge like First Aid courses.
In addition, your senior parent will be used to being in charge of their own home and is likely to feel like a bother as they begin to settle in your home. One effective way is to assign them a household responsibility. Ask your parents to look after the dog or cook a meal to make them feel like an active and important part of the family.

5 . Europe is the perfect place for a holiday. Every corner of the continent is bursting with history, culture and sights. The countries are so very close to one another, and yet so completely different.
Sweden
Sweden is a brilliant destination for a campervan (露营车) holiday, with hundreds of well-appointed camping sites suitable for vehicles. Head north to Lapland in the Arctic Circle and you’ll find true wildernesses where you can truly get close to nature. Head here between June and mid-July and you’ll be able to take in the midnight sunshine. If you’re looking for great nightlife, head to Gothenburg, Stockholm or Malmo.
Germany
There are massive industrial cities, rolling plains, towering mountains, deep forests and long, sparkling rivers. It’s not just what’s to see that makes Germany so great, but the ease of seeing everything. All these wonderful locations are all linked by one of the world’s best road systems.
Scotland
Scotland has something for everyone: cities with rich nightlife, incredible scenery, wonderful lochs and medieval (中世纪的) castles. If you want to get away from it all, then the Highlands are one of the least populated areas in the whole of Europe. Hikers will love the Cairngorms – the largest national park in the UK.
Spain
Spain’s famous for its beach holidays, but it offers so much more than that. With a lovely climate, rich history, excellent architecture, delicious cuisine and friendly locals, Spain has long been a favoured destination for holiday.

6 . Humans have been living and working on the space station for 20 years. Their meals are packaged, though sometimes astronauts receive fresh treats from resupply missions. The longer that packaged food is stored, the more it loses nutrients like vitamin C and vitamin K.
Astronauts have successfully grown 10 different crops on the space station since 2015 and had the chance to sample each one. The International Space Station hosted a party for astronauts on Friday as they celebrated the harvest of the first Chili (辣椒) grown in space. The crew finally had a chance to taste the peppers after initially kicking off the plant experiment on the space station in July.
Plant Habitat-04 is one of the most complex plant experiments on the orbiting laboratory to date because peppers take much longer to grow than the previous experiment plants. After growing for four months, the peppers were harvested on Friday.
Peppers provide a great source of vitamin C, as well as other key nutrients. Pepper plants self-pollinate, so they are easy to grow, and they are a pick-and-eat crop that doesn’t have to be cooked. They are also safe to eat raw.
A side effect of life in zero gravity is that astronauts often lose some of their taste and smell, so spicy or well-seasoned foods are a favorite. Adding fresh greens or peppers to the menu allows astronauts to liven up their regular meals. But growing and tending to the plants can also produce other benefits.
Astronauts have described the joy from seeing—as well as smelling and caring for—leafy green plants on the space station that remind them of Earth.
“Growing colorful vegetables in space can have long-term benefits for physical and psychological health,” said Matt Romeyn, principal investigator for the experiment.” We are discovering that growing plants and vegetables with colors and smells helps to improve astronauts’ well-being.”

7 . Scientists have discovered how plants manage to live alongside each other in places that are dark and shady. Plants in the deep darkness of a thick forest, where natural supplies are not very great in amount, won’t attempt to top their neighbors in growth as those in moderate (中度的) shade do. In deep shade conditions, it would be a waste of energy and harmful to survival because green shoots would never be able to top their larger neighbors in growth.
So how do plants prevent such growth in deep shade conditions? The secret lies in the clocks insides them, say scientists from the John Ines Centre and the University of Bristol.
They have discovered that when plants notice deep shade, this changes the expression of genes parts of the circadian clock (昼夜节律时钟) — the inner daily timer found in plants and other things. These clock parts perform an additional role in preventing plants from lengthening and overtopping neighbors.
The work identifies a previously unknown role of the circadian clock in controlling plant development and the findings may have possible effects on both natural plant populations and crops. Professor Antony Dodd of the John Innes Centre said, “The biological clock of plants plays a big part in their development and fitness. This work casts new light on a new role of the circadian clock in adapting plants to competition with other plants in their environments.” “It also gives us new insights into how plants adapt to very deep shade, where resources are very limited,” said Professor Kerry Franklin at the University of Bristol.
This work provides evidence for the firmness of the circadian clock in stressful environments, and information that may be useful in developing new generations of crops in a challenging climate.

8 . Most Famous Paintings in the World
Among the millions of paintings that are created and shown in galleries and museums all around the world, a very small number of them go beyond time and make history. Below are some examples.
The Persistence of Memory — Salvador Dali. Painted in 1931, The Persistence of Memory is one of the most recognizable pieces in art history. This work is known to make people reflect on their way of life and the way they spend their time, and it is also thought that Albert Einstein’s well-known Theory of Relativity gave Dali the idea for this wonderful painting.
Girl with a Pearl Earring — Johannes Vermeer. Considered by many to be “the Dutch Mona Lisa”, this beautiful painting features an unnamed young woman looking over her shoulder to stare directly at the viewer. It was completed in 1665 and is exhibited in the Mauritshuis in The Hague, the Netherlands.
Guernica — Pablo Picasso. The famous painting by Picasso was completed in 1937. It was painted in Paris following the bombing of Guernica during the Spanish Civil War. The painting is on permanent display in the Museo Reina Sofia, Madrid, Spain.
Starry Night — Vincent van Gogh. Painted in 1889, Starry Night is one of the most famous paintings in modern culture, which is part of the permanent collection of the Museum of Modern Art in New York. It is based on van Gogh’s direct observations as well as his imagination, memories, and emotions and was the inspiration for the song Vincent (also known as Starry, Starry Night).

9 . Piñatex is made from pineapple leaves that are left over after the fruit is harvested. It is an innovative way of using a product that would otherwise be thrown away, which reduces the amount of organic waste going to landfill and thus the methane emissions (沼气排放) that would result. Tough and durable, it is commonly used as an eco-friendly material for vegan leather by fashion designers.
Piñatex was developed by Dr. Carmen Hijosa, a Spanish leather goods expert who grew horrified at the environmental impact of leather production while working in the Philippines in the 1990s. Nor did she approve of the petroleum-based alternatives that are commonly used. At the same time, Hijosa noticed how some traditional Filipino garments（服装）were made from pineapple fibers, which kickstarted her research into how such a resource could be transformed into something more widely usable.
The fabric is made by extracting (提取) fibers from the pineapple leaves after harvest. They are washed and dried in the sun, then undergo a purification process that results in a soft fiber. This is mixed with corn-based polylactic acid (PLA) and turned into a non-woven product called “Piñafelt”, which is the base for Piñatex products.
Around 480 leaves from 16 pineapple plants go into the creation of a single square meter of Piñatex, which weighs and costs less than a comparable amount of leather. Because the fabric is natural, it is breathable, as well as flexible; it can easily be printed on and sewed. It’s produced in a roll, which means less waste than when an irregularly-shaped animal hide is used. But best of all, it can replace animal leather.
Piñatex is a multi-use material that is suitable for footwear, bags, clothing, pet leashes, and more. It has already been adopted by 1,000 shoe companies, fashion labels, and hotel chains around the world, including Hugo Boss, H&M, and the Hilton Hotel Bankside. The number of partnerships is likely to grow as more designers and consumers discover its benefits.

10 . A first grade teacher from Suffolk, Virginia found a way to teach her students about black history by taking them back in time to meet celebrated black figures. For each day of Black History Month, LaToya McGriff has dressed up like a famous African-American pioneer and taught her students about their significant contributions to the U.S.
On Monday, February 3, she dressed up as Virginian native Mary Jackson and began her creative class. “She was a mathematician who worked as an aeronautical (航空的) engineer whom people referred to as a human computer,” McGriff wrote on Facebook. She shared a photo of herself in 1960s clothing, like Jackson would have worn when she worked for NASA.
Jackson was one of the three “human computers” described in the book and film Hidden Figures, which revealed the African-American female mathematicians whose efforts helped put men on the moon.
Once McGriff started dressing up, she kept going. By February 18, McGriff's Black History Month lessons were starting to gain attention online. She was interviewed by CBS News, and said she works at a majority-black school and “wanted students to see that people who look like them contribute”.
She said that the seeds for this project were planted in her years ago by a teacher who did something similar. “That’s what I remember, having a teacher come dressed as a storybook character. Well, I could dress up as a different figure, an African-American figure from the past or present so they can see themselves represented,” McGriff said.
“My students will want to know who I will be tomorrow. Today, they just said ‘Are you going to be so-and-so?’ Because they want to know and kind of prepare themselves for it so that they can tell me something they know about the person,” she said.
McGriff said bringing history alive kept her students curious and asking questions, and she’s hoping the overall project will give them the confidence to know that, like these historic figures, they can be great, too.
