Every living thing carries a set of instructions written in DNA — the double helix discovered by Watson and Crick in 1953. For half a century, reading DNA was hard enough. Changing it was harder still. Then, in 2012, a technology called CRISPR-Cas9 arrived, and everything changed. CRISPR is a syste
For years, climate scientists have warned that rising sea levels, prolonged droughts and increasingly severe storms will displace millions of people. The term often used is "climate refugees" — people forced to leave their homes because the land can no longer support them. The reality, however, is m
At the start of the 15th century, the maps of the world drawn by European scholars showed Europe, Asia and North Africa — and little else. The Americas were unknown. The Pacific Ocean was a rumour. The southern tip of Africa had never been rounded by a European ship. Within 150 years, that would cha
In 2014, a leading technology company predicted that fully self-driving cars would be on the roads by 2018. In 2016, another major manufacturer promised autonomous vehicles by 2021. By 2020, several companies were offering limited self-driving taxi services in selected cities. A decade on from the f
For decades, the message has been simple: reduce, reuse, recycle. Plastic waste, in particular, is something that consumers are told to sort carefully, rinse clean and place in the correct bin. The assumption is that once the plastic leaves the home, it will be transformed into something new — a new
Sleep has long been a puzzle. Every animal with a nervous system sleeps, or at least rests in some way, yet the exact reason remains one of the great open questions of biology. For decades, scientists assumed that sleep was simply a period of rest — a time when the brain shut down to save energy. Mo
For most of the 20th century, going to work meant leaving the house, commuting to an office, sitting at a desk for eight hours and returning home. The office was not just a place; it was a structure around which daily life, family schedules and even urban planning were organised. The pandemic of 202
Every day, about 40 per cent of the actions people take are not decisions at all — they are habits. We brush our teeth, drink our morning coffee, scroll through our phones while waiting for the bus, all without consciously choosing to do so. Understanding how habits form, and how they can be changed
Writing is so much a part of daily life that it is hard to imagine a world without it. Yet for most of human history, people lived and died without ever seeing a written word. The earliest known writing systems emerged independently in at least three places: Mesopotamia around 3400 BCE, Egypt shortl
The human body is home to trillions of bacteria, most of which live in the digestive system. Collectively known as the gut microbiome, these microscopic organisms weigh about two kilograms and outnumber human cells by at least three to one. Far from being unwelcome guests, they play a central role i
For decades, computers have followed the same basic principle: information is stored and processed as a series of ones and zeros, called bits. Every photo, every email, every piece of software is ultimately a long string of these binary digits. Quantum computing promises to upend this entirely. Ins
On a hot summer day, the air above a city can be several degrees warmer than the surrounding countryside. This difference, known as the urban heat island effect, is not an illusion. It is a measurable phenomenon caused by the way cities are built. The main culprit is concrete and asphalt. These mat
When people think of bees, they picture meadows, wildflower fields and honeycomb hives in the countryside. But a growing body of research suggests that cities — long assumed to be biological deserts — may be some of the best places for bees to thrive. In a 2025 study of ten European cities, researc
Most people believe humans are different. The reason is that Homo sapiens has evolved to be conscious. Many animals feel pain and pleasure; some appear to be self-aware. But the human mind's unique potential to exhibit a sense of self marks out every member of the species for special treatment. In
Everything about a Greenland shark's life is slow: its heart beats about once every 12 seconds; it swims at an average speed of just a foot per second; it grows at a sluggish rate of just one centimeter a year; and it does not reach sexual maturity until its 150th birthday. This sluggish living make

"Why should taxpayers fund art galleries and orchestras when hospitals need money?"

Long before the internet connected continents, there was the Silk Road — a network of trade routes that linked China, India, Persia, Arabia and Europe for over 1,500 years.

For the first time in history, more than half of humanity now lives in cities. By 2050, that figure is expected to reach 68 per cent. This migration from countryside to city is the most significant social shift of our age — and it brings both enormous opportunities and severe challenges. Cities are
