In southern Portugal, particularly across the Alentejo region, the countryside is dotted with cork oak trees. Their trunks may look rough and deeply grooved, but the material they provide is familiar to people all over the world.

Cork.

Most of us know it as the stopper in a bottle. Far fewer know the careful work involved in harvesting it.

Skilled workers remove the outer bark by hand, using specialised axes and years of experience. The task requires a steady hand: cut too deeply and the living layer beneath can be damaged. Done properly, the tree remains standing and grows another layer of cork.

The bark is not harvested every year. After a harvest, the tree needs time to regenerate, with successive harvests generally separated by nine years. A cork oak can continue producing cork over a long life.

In the Alentejo, cork trees are part of a wider landscape known as the montado. Cork and holm oaks grow among pastureland and cultivated fields, supporting farming and providing habitat for wildlife. This landscape has been shaped by generations of people who have learnt to work with the trees rather than simply clear the land.

There is something extraordinary about a material that can be gathered without felling the tree that produces it. Yet the process is not effortless or automatic. The knowledge of when and how to harvest must be passed from experienced workers to the next generation.

Portugal is the world’s leading cork producer, and the craft remains part of its rural identity.

The next time you see a cork stopper, remember that it began as living bark on a tree that may still be growing in the Portuguese countryside.

Some of the most useful things we make come not from conquering nature, but from learning how to work with it.

Have you ever walked into a room and forgotten why you went there? Or felt certain that you had replied to an important message, only to discover later that you had not?

It happens to all of us. The trouble begins when we treat memory as though it were a perfectly organised filing cabinet.

It isn’t.

Our minds are good at remembering what matters to us, but they are not equally reliable at remembering every appointment, promise, deadline and small administrative detail. When we are tired or distracted, even something important can slip away.

There is a simple way to reduce that risk: stop asking your memory to do the work of a notebook.

When you agree to a meeting, put it straight into your calendar. When someone asks you to follow up, write down the task and the date. If a bill has to be paid, set a reminder rather than relying on the comforting thought that you will remember it later.

The important part is to record the detail when it first appears. Telling yourself that you will write it down in a minute is often how the detail disappears.

This habit is not a sign of a poor memory. It is a way of protecting your attention for things that genuinely need thought.

Once a task is safely recorded, you no longer have to keep bringing it back to mind throughout the day. You can concentrate on the conversation in front of you, the work you are doing or the person who needs your attention.

We often admire people who seem to remember everything. I suspect many of the most organised people have simply learnt which things not to leave to memory.

A small notebook or a well-used calendar may not look impressive.

But it can save you from a surprising number of unnecessary worries.

Some fish wait for food to fall into the water. The archerfish has a rather different plan.

It can shoot a narrow jet of water at an insect resting on a leaf or branch above the surface. If the aim is right, the insect falls into the water, where the fish can eat it.

That sounds simple until you remember that the target is not underwater. The fish must locate its prey above the surface and compensate for the way light bends as it passes from air into water.

The archerfish has evolved a way of doing this with remarkable accuracy. It presses its mouth into a small opening and forces water through it, creating a jet aimed at the unsuspecting insect.

Young archerfish can also improve their accuracy through practice, and hitting a target may become more difficult when the insect is farther away.

Imagine being an insect, resting quietly on a leaf, and suddenly finding yourself knocked into the water by a fish you had never even noticed.

The archerfish does not leap out of the water or chase its prey across the branches. It has found a way to bring the meal to itself.

Nature is full of hunters that run, fly, pounce or lie in wait. This one takes aim.

And for a fish, that is quite a remarkable way to have dinner.

Romania lies in southeastern Europe, between Central Europe and the Balkans. Beyond its well-known castles and mountain landscapes, the country has villages where traditional crafts remain part of everyday cultural identity.

One such place is Horezu, in the region of Oltenia. Its pottery is recognised for distinctive patterns, carefully shaped forms and techniques passed from one generation of craftspeople to the next. The work is not simply about producing a useful bowl or plate. It carries the habits, designs and knowledge of a community.

A potter begins with ordinary clay. Through practice and a trained eye, the material becomes something that can be used at home, displayed with pride or passed on as a gift. The decoration may include familiar motifs drawn from the natural world, alongside patterns associated with the local tradition.

What makes Horezu especially interesting is that the craft has not survived only as an object in a museum. Skilled artisans continue to practise it, keeping the knowledge alive through making and teaching.

UNESCO recognised the craftsmanship of Horezu ceramics as Intangible Cultural Heritage in 2012. The recognition reflects something larger than the beauty of the finished pottery: the importance of the people who preserve the skills behind it.

A handmade vessel may appear modest beside a grand monument. Yet it can carry something that a monument cannot easily show—the patient knowledge of one generation, placed into the hands of the next.

When something goes wrong, our first reaction is often to ask, “Why does this always happen to me?”

It is an understandable question, especially when several disappointments arrive close together. But it rarely helps us decide what to do next. Instead, it can make one difficult incident feel like proof that everything is going wrong.

There is another question worth trying.

“What can I do about this now?”

It does not deny the problem. It does not pretend that unfairness, disappointment or bad luck can be wished away. It simply brings our attention back to the part of the situation we may still be able to influence.

Perhaps a letter has gone unanswered. We can decide when to follow up.

Perhaps a plan has failed. We can examine what went wrong before deciding whether to try again.

Perhaps somebody has misunderstood us. We can make one more honest attempt to explain, without assuming that we can control the other person’s response.

Not every problem has a neat solution. Some require patience, and others require us to accept what cannot be changed.

But there is a difference between accepting a difficult situation and surrendering our entire day to it.

The next time something upsets you, give yourself a little time to feel disappointed. Then ask what remains within your hands.

You may not be able to change what happened.

You may still be able to decide what happens next.

Imagine losing a leg and growing a new one—not a substitute, not a crude copy, but a functioning limb with bones, muscles, nerves and skin.

The axolotl, a salamander native to Mexico, can do something remarkably close to that.

When it loses a limb, the wound does not simply close over and leave a permanent stump. Cells near the injury take part in a carefully coordinated process that rebuilds the missing structures. Researchers study how the animal’s tissues know what to replace and how to restore the limb’s organisation.

The axolotl can also regenerate other body parts, including portions of its tail and certain damaged tissues. Its abilities have made it an important subject in research on regeneration.

Of course, this does not mean that humans can grow back an arm or leg. Our bodies have much more limited regenerative abilities, and scientists are still working to understand the mechanisms involved.

But the animal raises an extraordinary question: what determines whether an injury leaves a permanent scar or becomes the beginning of something new?

The answer is not simple. It involves signals between cells, the organisation of tissues and the way a developing body knows what belongs where.

For such a small creature, the questions it presents to science are enormous.

The axolotl is not trying to teach us a lesson. It is simply surviving in the way its biology allows.

Yet it reminds us how much remains to be discovered about the living world—even about something as familiar as the body’s ability to heal.

Ireland lies on the western edge of Europe, across the Irish Sea from Great Britain. In many parts of its countryside, particularly in the west, the landscape is divided by stone walls that seem to have grown naturally from the ground.

Look closely, and you discover that these walls have been built without mortar or cement.

The craft is known as dry-stone construction. Each stone must be chosen and positioned so that it helps support the stones around it. A wall that looks irregular to an untrained eye may contain the result of years of practical knowledge, passed from one generation to the next.

In Ireland, these walls have served ordinary purposes: keeping livestock within fields, marking boundaries and clearing stones from land that could then be cultivated. The work demanded patience and a feel for the shape and weight of individual stones.

The tradition is not merely a relic of the past. Farmers and skilled wallers continue to repair old structures, while community groups and training workshops help keep the craft alive. In 2024, Ireland’s dry-stone construction tradition received recognition through UNESCO’s Intangible Cultural Heritage programme.

I find something satisfying about this kind of craftsmanship. There is no machine that can simply make every decision for the builder. The person has to look, judge, adjust and try again.

A well-built wall may stand for generations, quietly doing its job while the world around it changes.

Perhaps the finest traditions are not those preserved untouched behind glass, but those people still find useful enough to practise.

Across the Irish countryside, stone by stone, that knowledge continues.

Sometimes a single word can make a difficult situation worse.

It is the word always.

“You always misunderstand me.”
“You never listen.”
“You always do this.”

Once those words enter a conversation, the original problem often disappears. The other person begins searching for exceptions, defending old decisions and remembering occasions when the accusation was unfair. Before long, two people who might have solved a small problem are arguing about the entire history of their relationship.

I have seen how easily this happens. A disagreement that could have ended in a few minutes becomes a wound that takes days to heal.

There is a simple alternative. Describe what happened today, rather than passing judgement on someone’s entire character.

Instead of saying, “You never listen to me,” try saying, “I felt hurt when I couldn’t finish what I was saying.”

The second sentence does not guarantee agreement, but it gives the other person something specific to understand. It leaves room for an explanation, an apology or even a difference of opinion.

This is not about choosing polite words to hide what we really feel. Some things need to be said firmly. But firmness and accusation are not the same thing.

As we grow older, we learn that winning an argument does not necessarily mean we have protected a relationship. Sometimes we prove our point and lose the willingness of another person to hear us again.

The next time anger tempts you to use always or never, pause for a moment. Ask yourself whether you are trying to solve the problem or simply make the other person feel the weight of your frustration.

A conversation cannot always end in agreement.

It can, however, end without leaving a fresh injury behind.

If a small creature could win a boxing match against an animal many times its size, you might suspect a mistake in the rules.

Meet the mantis shrimp.

Despite its name, it is neither a mantis nor an ordinary shrimp. Some species possess specialised appendages that strike with extraordinary speed, allowing them to crack hard shells and capture prey.

The astonishing part is how quickly the strike happens. The movement is so rapid that it can create a brief bubble of low pressure in the surrounding water. When that bubble collapses, it releases additional energy in a phenomenon known as cavitation.

In other words, the target may experience more than the direct impact.

These animals are small, but their equipment is remarkably effective. Their specialised striking limbs are built for a very particular job, and they use them with precision.

It is tempting to imagine the mantis shrimp as an angry little boxer, picking fights beneath the sea. In reality, it is simply using the tools that evolution has given it to survive.

Still, the thought is amusing. Somewhere on the ocean floor, a creature small enough to fit in your hand carries a punch that engineers have studied for its unusual mechanics.

The sea has no shortage of beautiful things. But occasionally it produces something that makes you wonder whether nature has a sense of humour.

Mongolia is a vast, landlocked country in East Asia, lying between Russia to the north and China to the south. Beyond its capital, Ulaanbaatar, stretches a landscape of open grasslands, mountains and desert, where seasonal changes can shape the rhythm of daily life.

For some Mongolian herding families, home is a ger—a round dwelling built around a collapsible wooden frame and covered with layers of felt. It is not simply a tent. It is a carefully adapted home, designed to be dismantled, transported and assembled again.

That makes sense in a place where families may move with their livestock in search of suitable pasture. A permanent building can tie a household to one location; a ger allows the home to travel with the people who live in it.

Inside, the arrangement has its own familiar order. The central stove provides warmth and a place for cooking, while the circular structure makes practical use of the available space. The thick covering helps protect the family from Mongolia’s severe winter cold and changing weather.

Yet the most interesting part may be the idea behind it. A home does not always have to be fixed to the ground to provide stability. The walls can be taken apart, the belongings packed, and the dwelling rebuilt somewhere else.

Of course, life on the steppe is not easy, and not every Mongolian lives this way today. Modern cities, schools, jobs and changing circumstances have transformed the country.

Still, the ger remains a powerful example of practical ingenuity: a home shaped around the needs of the people rather than the other way around.

Perhaps that is a useful thought to carry beyond Mongolia. We often spend years building a life around things that cannot move. There is something admirable about a home designed to adapt when life itself requires a change.
