The possibility of time travel is indeed attractive. Stories exploring the subject have been around for hundreds of years. Perhaps the best-known example is science fiction novel The Time Machine, written by H. G. Wells and published in 1895. It was adapted into at least two feature films of the same name, as well as two television versions, and a large number of comic book adaptations. It is generally credited with the popularization of the concept of time travel using a vehicle that allows an operator to travel purposefully and selectively. The term "time machine", coined by Wells, is now universally referred to a vehicle transporting people into the far future.

But could time travel actually be possible? Some scientists say yes, in theory. They propose using cracks in time and space called "wormholes", which could be used as shortcuts to other periods. Einstein's theory of relativity allows time travel in extreme conditions. And Stephen Hawking says you could travel into the future with a really fast spaceship, going at nearly the speed of light. Though building such a spaceship wouldn't of course be simple.

Even if you could travel into the past, there is something called the "grandfather paradox". It asks what would happen if a time traveler were to go back in time and have his own grandfather killed for some reason, and therefore prevent himself from being born. If the time traveler wasn't born, how would he travel back in time?

And would you really like to visit the future? In H. G. Wells' book, the main character travels into distant time where he arrives at a beach and is attacked by giant crabs. He then voyages 30 million years into the future where the only living thing is a black object with tentacles.

If that's what's in store, maybe we are better just living in the present day after all.

Here's the thing — I do not have a cat. And this was not the first time this particular cat had demanded my attention.

I immediately calmed down and realized my error — I had left a window open. I approached to entertain my house-guest by giving her some treats and a scratch under her collar (颈圈).

Like so many others, I shifted from working in an office to working from home. Living alone can be isolating at the best of times. It was around the one-month mark of the lockdown when I heard a meow outside my window. Sitting outside on the grass was a long-haired, golden-colored cat. I opened the window, and this beautiful cat jumped into my home. Her short visit brightened my day.

A few days later, I heard a familiar meow. I saw a name tag on her collar: Mika. On this second visit, I also noticed Mika was cross-eyed, which only made her more lovely.

Over the next few weeks, Mika would stop by occasionally. Sometimes, she only stayed for a few minutes; other times, she would wander around my apartment much longer. Each visit brightened me. Mika even helped me connect with some new neighbors, who asked if Mika was my cat. Apparently, Mika visited them as well.

While the lockdown has been awful, I suspect I might not have ever met Mika if it had not happened. But perhaps she came by at this time because she sensed a need for connection on my part.

While dogs are said to be man's best friend, a good cat can be everyone's best friend.

Visit an "abandoned" Tube station underworld and discover what secrets are hidden beneath our busy streets in our new Hidden London exhibition at London Transport Museum!

Hidden London: the Exhibition takes you on a journey of some of London's most secret spaces in the world's oldest underground system. These "forgotten" parts of the Tube network have incredible stories to tell about Britain's wartime past.

You can enjoy the largest number of rare photos and objects from disused stations that have been brought together in one location.

Discover stories about how Churchill took shelter at the height of the Blitz deep underground at Down Street station. See how shelterers lived down at Clapham South station, where they slept and how they kept entertained.

You can also explore other locations that we have recreated in our Global Gallery, including the historic abandoned ticket hall at Aldwych station with an original 1930s ticket office.

The exhibition uncovers why these "lost" parts of the underground network exist. Changes in population, economic priorities and political pressures have all led to spaces being abandoned. But they rarely stay that way. While some sections of the Tube system lie "forgotten", many have been repurposed for new activities and are used for special Hidden London tours, growing salad leaves, and for filming locations, including Charing Cross, which featured in Skyfall (2012).

The morning sun shone through the curtains as I stood in the kitchen, carefully preparing lunch for my daughter, Emma. Today was a big day — her first day of elementary school. I packed her lunch in a bright, reusable lunchbox, the same kind my mother used to pack for me when I was a student.

"Mom, why can't I use a plastic lunchbox like the other kids?" Emma asked, her small face frowning in confusion. I knelt down to her level, moving a piece of hair out of her face. "This lunchbox is part of our family tradition, sweetheart. When I was your age, your grandmother would pack my lunch in a similar container every day." "But why, Mom?" she persisted(坚持不懈). "Isn't it easier to just throw away a plastic lunchbox?"

I smiled and remembered my own school days, feeling frustrated(沮丧的)that I couldn't just use a disposable(一次性的)box like everyone else. My mother would patiently explain, "We have to start with small actions, Mija. These little things add up to make a big difference."

I remembered feeling out of place at school as my friends casually threw their plastic boxes into the trash, while I carefully saved my containers to take back home. It wasn't untill was older that I fully appreciated the lesson my mother was teaching me.

Then I patiently explained to Emma, "Your grandmother always said that we have to take care of our planet. By using these reusable lunchboxes, we help reduce waste and protect the environment. It's a small way to make a big difference."

Emma looked at the lunchbox thoughtfully. "So, do I have to wash it after I eat?" "Yes," I nodded. "It's important to take care of it and bring it back home so we can use it again. It's not just about the lunchbox, Emma. It's about learning to be responsible and thinking about how our actions affect the world around us."

Have you ever struggled to understand how someone else feels? There are some strategies to help build up your empathy.

Accept Weakness

Showing your bad side can be embarrassing, but it's a powerful way to connect with others. We all have insecurities and fears. . When someone shares their weakness with you, respond with empathy and share your own struggles when appropriate. This creates a mutual understanding and deepens the connection.

Set Aside Assumptions and Judgments

It's easy to jump to conclusions based on our own experiences, but empathy requires us to put these aside. . Listen without planning your answers or thinking about how to solve their problems. Sometimes, your friends just need to feel heard and understood, not advised or judged.

Activate (激活) Your Imagination

. Use your imagination to empathize with experiences beyond your own, like the excitement of a new discovery. Reading widely and exposing yourself to diverse life stories can also enhance your ability to empathize. , not to make up or exaggerate (夸大) your own experiences.

Practice Active Listening

Listening actively means being fully engaged (参与) in what the other person is saying without distractions. Imagine that your friends are talking to you, and give them your full attention. Make eye contact, nod to show you understand, and offer a soft smile to make them feel valued. Remember, active listening isn't just about hearing words. . Be empathy that helps them explore their own feelings more deeply.

Dr. Gilligan and his co-authors reexplain the evidence of recent discoveries in the development of clothing. "Why do we wear clothes? We think that it's part of being human. When you look at different cultures, you realize that people existed and functioned perfectly enough in society," Dr. Gilligan says. "What interests me is the change of clothing from being a physical necessity in certain environments, to a social necessity in all environments."

The earliest known eyed needles appeared about 40,000 years ago in Siberia. One of the man-made objects from the Stone Age, eyed needles are more difficult to make when compared to bone awls (尖钻), which was used for creating fitted clothing. Bone awls are tools made of animal bones that are sharpened. Eyed needles are revised bone awls, with a hole in them. As evidence suggests bone awls were already being used to create tailored clothes, the innovation of eyed needles may reflect the production of more complex (复杂的) clothing, as well as the decoration of clothes by attaching small decorative items onto them.

Dr. Gilligan and his co-authors argue that clothing became an item of decoration because traditional body decoration methods, like body painting, weren't possible during the latter part of the last Ice Age in colder parts of Eurasia, because people were needing to wear clothes all the time to survive.

The changes of clothing allowed larger and more complex societies to form, as people could relocate to colder climates while also cooperating with their community based on shared clothing styles and symbols. The skills associated with clothing contributed to a more sustainable (可持续的) lifestyle and improved the long-term survival and prosperity of human communities.

Vermillion is an architect and designer. He creates artwork of spaces. Before he started using AI to do this, Vermillion would make maybe 10 pieces in a year. Last year, though, he made around 150 works. "I can just simply tell the computer what I want in simple English," he says. "What a time to be alive!"

Many other artists, though, aren't so ecstatic about AI-generated art. Katria Raden is an independent illustrator and author. People used to hire her regularly to create art for marketing materials or to illustrate children's books. Last year, almost no one reached out about these types of jobs. The rise of AI may help explain this. "At times I think it's a bad dream," she says. "I feel scared and angry, but also pretty sad."

Using AI to create an image is quick and easy. There are many popular image generators. They are cheap or even free to use. They also pose threats to some artists' jobs.

But the problems go deeper than that. These images were scraped (勉强获得) from the Internet. Data scraping automatically pulls files from web pages. Often, no one asks permission or checks what these files contain. Thousands of artists' names and works have been found in the data set. Illegal or harmful images and people's personal photos are also among those data.

Raden doesn't like the way AI image generators were trained or how they're being used. "It will have a bad effect," she says. Many artists agree with her.

Vermillion sees their point. But for him, the rise of AI tools has been mostly positive. At design workshops he runs, he always asks people how they use AI in their works. He recalls one participant saying, "Sometimes I just need a creative partner that doesn't think like I do." AI, he feels, can play that role.
